Alternatively, a high-frequency acceleration fluctuation component may be removed by using an appropriate low-pass filter (not shown). By providing in this way, a variable acceleration (component) that will be irregularly applied to the portable information terminal 10 due to being held and carried by a distance learning student and a gravitational acceleration that does not change 100 (display screen long side direction component 100a, display screen short side direction component 100b) can be distinguished and detected. In one embodiment, the acceleration (component) detected by the roll, pitch, and yaw movement of the portable information terminal 10 detected by the acceleration sensor 12 that is arranged offset from the center of gravity of the portable information terminal 10 is detected by gravity.

It is good also as what is provided so that it may detect. In this case, the component component of the other gravitational acceleration 100 to be compared with the detected component component of the gravitational acceleration 100 may be estimated and determined by the drawing unit 14 described in detail later.

  The estimation of another component component based on the detection of one component component of the gravitational acceleration 100 (see FIG. 2) by the acceleration sensor 12 provided in the portable information terminal 10 of the present embodiment will be described. For example, the display screen of the gravitational acceleration 100 detected along the display screen long side direction 11a (see FIG. 2) of the liquid crystal display screen 11 (see FIG. 2) by the acceleration sensor 12 included in the portable information terminal 10 of the present embodiment. The long side direction component 100a (see FIG. 2) can be compared with the value of the standard gravitational acceleration 100 on the earth (for example, 9.80665 m / s ^ 2). In this case, for example, the inclination angle θ (see FIG. 2) of the portable information terminal 10 with respect to the vertical direction can be estimated by using trigonometry (inverse cosine function). Further, the display screen short side direction component 11b (see FIG. 2) of the gravitational acceleration 100 can be simultaneously estimated by the trigonometric method (sine function) based on the estimated inclination angle θ. For this reason, only the component component of the gravitational acceleration 100 along the detection axis in either the long side direction 11a or the short side direction 11b of the liquid crystal display screen 11 is detected. Even when the acceleration sensor 12 is used, the long side direction component 100a and the short side direction component 100b of the gravitational acceleration 100 can be detected, estimated, and compared.

  A rotation detection device provided in portable information terminal 10 of the present embodiment will be described. The portable information terminal 10 according to the present embodiment takes distance learning by detecting a rotation (angular velocity, angular acceleration) 200 (see FIG. 2) around the normal axis of the liquid crystal display screen 11 (see FIG. 2). A gyro sensor 13 is provided as a rotation detection device that can detect the posture (rotation angle) of the portable information terminal 10 that is typically held and operated by one hand. The gyro sensor 13 provided in the portable information terminal 10 of the present embodiment is provided with a vibration type gyro sensor in which a rotation detection circuit for detecting an angular velocity or angular acceleration of the rotation 200 around one detection axis is incorporated in a semiconductor package. Good. The gyro sensor 13 provided in the portable information terminal 10 according to the present embodiment may be provided in a small and lightweight manner by using a MEMS (Micro-Electro-Mechanical-Systems) technology. Or the gyro sensor 13 with which the portable information terminal 10 of this Embodiment is provided measures the optical path difference of a laser beam using the mirror or optical fiber which can detect the angular velocity or angular acceleration of rotation of the portable information terminal 10 more precisely. An optical gyro sensor may be used. The gyro sensor 13 provided in the portable information terminal 10 of the present embodiment is provided so as to output detection of rotation (angular velocity or angular acceleration) 200 around the normal axis of the liquid crystal display screen 11 as digital signal information as needed. Good.

  Detection of angle (attitude) of rotation 200 of portable information terminal 10 based on detection of angular velocity and angular acceleration of rotation 200 (see FIG. 2) of portable information terminal 10 by gyro sensor 13 provided in portable information terminal 10 of the present embodiment. Will be described. The gyro sensor 13 included in the portable information terminal 10 of the present embodiment typically has an angular velocity of rotation 200 about the normal axis passing through the center of gravity (intersection of diagonal lines) of the liquid crystal display screen 11 (see FIG. 2). Alternatively, it may be provided so as to detect angular acceleration. However, since the gyro sensor 13 only needs to be able to detect the rotation 200 of the portable information terminal 10 (the liquid crystal display screen 11), the gyro sensor 13 is not limited to the center of gravity position of the liquid crystal display screen 11. The rotation (angular velocity, angular acceleration) 200 around the normal axis of the liquid crystal display screen 11 passing through a point may be detected. When the gyro sensor 13 included in the portable information terminal 10 according to the present embodiment continuously outputs the angular acceleration of the rotation 200 of the portable information terminal 10, the portable information terminal 10 integrates the output angular acceleration with time by performing second-order integration. The angle of the rotation 200 around the axis in the normal direction of the liquid crystal display screen 11 of the information terminal 10 can be detected. Alternatively, when the gyro sensor 13 continuously outputs the angular velocity of the rotation 200 of the mobile information terminal 10, the normal direction of the liquid crystal display screen 11 of the mobile information terminal 10 is obtained by integrating the output angular velocity with time. It is possible to detect the angle of the rotation 200 around the axis.

  In addition, since the portable information terminal 10 of this Embodiment is equipped with both the acceleration sensor 12 and the gyro sensor 13, it is for the detection of the angle of rotation 200 (refer FIG. 2) of the portable information terminal 10 by the gyro sensor 13. FIG. The initial value (initial angle) is preferably determined by detecting (estimating) the aforementioned inclination angle θ (see FIG. 2) by using the acceleration sensor 12. Alternatively, the rotation of the portable information terminal 10 is performed with the angle (attitude) of the portable information terminal 10 when the first information window 1 (see FIG. 2) is displayed on the liquid crystal display screen 11 by the drawing unit 14 described in detail later as an initial value ( (Angular velocity, angular acceleration) 200 may be calculated by integration.

  A drawing (display) device provided in portable information terminal 10 of the present embodiment will be described. The drawing unit 14, which is a drawing (display) device included in the portable information terminal 10 of the present embodiment, is configured by a graphic chip (graphic circuit) that can freely draw (display) information on the display screen 11. Good. The drawing unit 14 included in the portable information terminal 10 of the present embodiment includes the acceleration sensor 12 that detects the gravitational acceleration 100 (see FIG. 2) and / or the normal line of the liquid crystal display screen 11 of the portable information terminal 10 (see FIG. 2). The drawing (display) may be performed with reference to the detection result of the gravity acceleration 100 and / or the rotation 200 by the gyro sensor 13 that detects the rotation 200 around the direction axis (see FIG. 2). The drawing unit 14 included in the portable information terminal 10 according to the present embodiment displays information windows 1 and 2 on the liquid crystal display screen 11 according to the detection result of the gravitational acceleration 100 and / or the rotation 200 by the acceleration sensor 12 and / or the gyro sensor 13. (Refer to FIG. 2) is displayed, and the screen display of the liquid crystal display screen 11 is preferably switched.

  The display and switching of the information windows 1 and 2 (see FIG. 2) by the drawing unit 14 included in the portable information terminal 10 of the present embodiment will be described. As will be described in detail later, the drawing unit 14 included in the portable information terminal 10 of the present embodiment divides the liquid crystal display screen 11 (see FIG. 2) into two display areas and displays two pieces of different information. The information windows 1 and 2 can be displayed side by side D02 (see FIG. 2) (second display mode). In addition, the drawing unit 14 selects one information window D01S (see FIG. 5) according to the information window display standard D01SS (see FIG. 5), which will be described in detail later, and enlarges the selected information window to the liquid crystal display screen 11. Display D01 (see FIG. 2) can be made (first display mode). Furthermore, the drawing unit 14 changes the first display mode (enlarged display) D01 and the second display mode (two-screen parallel display) D02 according to the detection results by the acceleration sensor 12 and the gyro sensor 13 to the information window display reference D01SS. Can be displayed (drawn) on the liquid crystal display screen 11 by switching at any time according to the conditions defined by the above. For this reason, the portable information terminal 10 according to the present embodiment switches the display mode (drawing mode) of the liquid crystal display screen 11 at any time according to the operation of tilting (rotating) the portable information terminal 10 by a distance learning student. Display (drawing) can be performed.

  Another configuration provided in the portable information terminal 10 of the present embodiment will be described. In addition to this, the portable information terminal 10 of this embodiment includes a microprocessor (MPU) 20 that is a small central processing unit that performs overall information processing and control in the portable information terminal 10. In addition, a random access memory 22 (RAM) that assists each function and operation of the display screen 11, the acceleration sensor 12, the gyro sensor 13, the drawing unit 14, and the information communication unit 15 is provided. In the present embodiment, the information window display reference D01SS is recorded and stored in the recording storage unit 21, but in one embodiment, the information window display reference D01SS is recorded in the random access memory (RAM) 22. It may be stored. Alternatively, in another embodiment, the information window display reference D01SS may be built into the microprocessor (MPU) 20 and configured in hardware.

  With reference to FIG. 2 showing switching of screen display, display and switching of information windows 1 and 2 on liquid crystal display screen 11 by drawing unit 14 (see FIG. 1) provided in portable information terminal 10 of the present embodiment. Is described with an example. FIG. 2A shows an example of display and switching of the information windows 1 and 2 when the information to be displayed on the liquid crystal display screen 11 is horizontally long C01 information. FIG. 2B shows an example of display and switching of the information windows 1 and 2 when the information to be displayed on the liquid crystal display screen 11 is vertically long C02 information.

  An initial display direction determination C01 / C02 of the information windows 1 and 2 performed by the drawing unit 14 (see FIG. 1) included in the portable information terminal 10 of the present embodiment will be described. Whether the drawing unit 14 included in the portable information terminal 10 of the present embodiment should initially display information in the horizontally long C01 or display information in the vertically long C02 according to the information to be displayed. It is recommended that the display (drawing) be performed automatically. For example, the drawing unit 14 has information (designated as information to be displayed in the first and second information windows 1 and 2) that is specified by the distance learning student as the number of pixels (screen size, In the case of video information composed of images in the graphic mode), it is determined that the information is initially displayed (drawn) in the landscape C01 by comparing the aspect ratio of the number of pixels of the information to be displayed. Good. Alternatively, the drawing unit 14 may perform, for example, face detection or character detection by image analysis of information (image) to be displayed, and determine the horizontal C01 or the vertical C02 of the information to be displayed.

  Specifically, the information to be initially displayed (for example, information to be displayed in the first information window 1) is, for example, a landscape (video 1600 × length 1200 pixels) that is a video of a lecturer who performs distance learning. In the case of the video information 300 of C01 (see FIG. 9), the drawing unit 14 (see FIG. 1) decides to display the first information window 1 in the horizontally long C01 (see FIG. 2A). It is good to do. On the other hand, the information to be initially displayed (for example, the information to be displayed in the first information window 1) is, for example, document information of C02 that indicates a document of A4 standard in a portrait (1600 × 2400 pixels) C02 document information. In the case of (not shown), the drawing unit 14 may determine to display the first information window 1 in the vertically long C02 (see FIG. 2B). Note that the top / bottom direction (vertical C01 / horizontal C02) of information can typically be determined and specified by the information provider. For example, the information provider detects the top-to-bottom direction of the image by taking a picture with a digital camera (not shown) provided with an acceleration sensor 12 (see FIG. 1) that detects the gravitational acceleration 100. It can be determined and specified by the gravitational acceleration 100.

  An initial drawing direction (display mode D01 / D02) discrimination D00V (see FIG. 5) by the drawing unit 14 (see FIG. 1) provided in the portable information terminal 10 of the present embodiment will be described. The drawing unit 14 included in the portable information terminal 10 according to the present embodiment includes the gravity acceleration 100 detected by the acceleration sensor 12 (see FIG. 1) and / or the gyro sensor 13 (see FIG. 1) and / or the rotation of the portable information terminal 10. Based on the (angle) 200, it is possible to detect in which direction the distance learning student is holding the portable information terminal 10. For this reason, the drawing unit 14 determines the initial screen display (drawing direction, one-screen display D01 or two-screen display D02) of the information to be displayed in the first and second information windows 1 and 2, and determines the information by D00V. The windows 1 and 2 may be displayed.

  For example, as shown in FIG. 2A, when the information to be drawn first (information to be displayed in the information window 1) is horizontally long C01, the distance learning student puts the portable information terminal 10 in the vertically long D02. When gripped, the drawing unit 14 (see FIG. 1) may display the first and second information windows 1 and 2 side by side on the liquid crystal display screen 11 in a two-screen display D02. In this case, the drawing direction (horizontal C01) of the information to be drawn first (information to be displayed in the information window 1) does not match the holding direction (vertical D02) of the portable information terminal 10 by the distance learning student ( It can be said that it was what was shown in FIG. On the other hand, when the information to be drawn first (information to be displayed in the information window) is the horizontally long C01, and the distance learning student holds the portable information terminal 10 in the horizontally long D01, the drawing unit 14 The first information window 1 may be enlarged and displayed on the liquid crystal display screen 11 by the one-screen display D01. In this case, the drawing direction (horizontal C01) of the information to be drawn first (information to be displayed in the information window 1) coincides with the gripping direction (horizontal D01) of the portable information terminal 10 by a distance learning student ( This can be said to have been performed.

  The top and bottom direction determinations D01V and D02V (see FIGS. 5 and 6) by the drawing unit 14 (see FIG. 1) provided in the portable information terminal 10 of the present embodiment will be described. The drawing unit 14 determines whether the information is horizontally long C01 / vertically long C02, and determines whether it should be initially displayed in the first display mode D01 or in the second display mode D02 (see FIG. 5). ), The vertical direction of the portable information terminal 10 is detected and the vertical direction (one lower side) of the liquid crystal display screen 11 is determined D01V, D02V.

  For example, in the display of the horizontally long C01 information on the liquid crystal display screen 11 shown in FIG. 2A, the drawing unit 14 (see FIG. 1) includes the acceleration sensor 12 (see FIG. 1) and / or the gyro sensor 13 (see FIG. 1). The detection result (referred to) (gravitational acceleration (direction) 100 and / or rotation (angle) 200 of the portable information terminal 10) can be grasped. Therefore, the drawing unit 14 displays the information windows 1 and 2 in either the one-screen display D01 or the two-screen display D02 in any display mode. Display D01V and D02V (see FIG. 5) can be performed in combination with the lower side direction (vertical downward direction) of the liquid crystal display screen 11 included in the portable information terminal 10 held by the student.

  Similarly, using the example shown in FIG. 2 (b), for example, when the information to be drawn first (information to be displayed in the information window 1) is a vertically long C02, the distance learning student receives the mobile information. When the terminal 10 is held in the horizontally long D02, the drawing unit 14 (see FIG. 1) displays the first and second information windows 1 and 2 side by side in the two-screen display D02 on the liquid crystal display screen 11. Good. In this case, the drawing direction (vertical C02) of the information to be drawn first (information to be displayed in the information window 1) does not match the gripping direction (horizontal D02) of the portable information terminal 10 by a distance learning student ( It can be said that it was what was shown in FIG. On the other hand, when the information to be drawn first (information to be displayed in the information window 1) is the vertically long C02 and the student of distance learning holds the portable information terminal 10 in the vertically long D01, the drawing unit 14 may display the first information window 1 on the liquid crystal display screen 11 in an enlarged manner by the one-screen display D01. In this case, the drawing direction (vertical C02) of the information to be drawn first (information to be displayed in the information window 1) coincides with the gripping direction (vertical D01) of the portable information terminal 10 by the distance learning student ( It can be said that it was what was carried out).

  At this time, the drawing unit 14 (see FIG. 1) detects the detection result (gravitational acceleration (direction) 100 and / or the portable information terminal 10) by the acceleration sensor 12 (see FIG. 1) and / or the gyro sensor 13 (see FIG. 1). Rotation (angle) 200) can be grasped. Therefore, the drawing unit 14 displays the information windows 1 and 2 in the display mode of either the one-screen display D01 or the two-screen display D02. The display D01V and D02V (see FIG. 5) can be performed in accordance with the lower side direction (vertical downward direction) of the liquid crystal display screen 11 provided in the portable information terminal 10 held by the student, that is, in the vertical direction. .

  Switching of the screen display of portable information terminal 10 of the present embodiment will be described. The mobile information terminal 10 according to the present embodiment tilts the mobile information terminal 10 tilted to the left by the distance learning student D02B or the right from the state where the two-screen display D02 is initially displayed on the liquid crystal display screen 11. It is preferable that the screen display is provided so as to be switched to the single screen display D01 in accordance with the operation D02C. One information window to be displayed in the one-screen display D01 is selected depending on whether the student of distance learning performs the operation D02B for tilting the portable information terminal 10 to the left or the operation D02C for tilting to the right. The information window may be selected D01S (see FIG. 5) by the drawing unit 14 (see FIG. 5) according to the information window display standard D01SS (see FIG. 5). The distance learning student can tilt the portable information terminal 10 to the left or right is specially easy when the distance learning student holding the portable information terminal 10 with one hand mainly rotates his wrist and rotates the portable information terminal 10 200. This is an operation that can be performed. For this reason, the distance learning student can integrate the information displayed in the first and second information windows 1 and 2 or compare them with each other for reference, and select D01S. The one-screen display D01 that can be referred to in detail by enlarging the one information window can be arbitrarily switched.

  Switching of screen display (display mode) performed by tilting portable information terminal 10 of this embodiment to the left and right will be described. As described above, switching between the two-screen display D02 and the one-screen display D01 of the portable information terminal 10 of the present embodiment is performed in the direction of the long side of the display screen of the gravitational acceleration 100 detected by the acceleration sensor 12 (see FIG. 1). It may be performed by comparing the component 100a with the display screen short side direction component 100b. For example, in the case of D02B in which the portable information terminal 10 is gradually tilted to the left from the state of the two-screen display D02, for example, as shown in FIG. 2A, the display screen of the gravitational acceleration 100 detected by the acceleration sensor 12 The long side direction component 100a gradually decreases from 1G, which is a standard gravitational acceleration value on the earth. On the other hand, the display screen short side direction component 100b of the gravitational acceleration 100 gradually increases from 0G. Therefore, when the ratio of the gravitational acceleration 100 to the display screen short side direction component 100b of the display screen long side direction component 100a reaches a predetermined ratio (threshold) determined by the information window display standard D01SS (see FIG. 5), D02B (D02A ) To switch from the two-screen display D02 to the one-screen display D01.

  For example, the threshold when D02B (D02A) for switching from the two-screen display D02 to the one-screen display D01 is the information window display standard D01SS (see FIG. 1) recorded and stored by the recording storage unit 21 (see FIG. 1) included in the portable information terminal 10. 5)). The predetermined ratio (threshold value) of the display screen long side direction component 100a of the gravitational acceleration 100 determined by the information window display standard D01SS to the display screen short side direction component 100b is, for example, from a distance learning student holding the portable information terminal 10 It may be determined to be 1 at D02B when the tilt angle θ of the display screen long side direction component 100a from the viewing vertical direction to the left is 45 degrees to the left.

  In the case of C01 / D02B in which the portable information terminal 10 is tilted to the left in FIG. 2A, the ratio of the display screen long side direction component 100a to the display screen short side direction component 100b is along the cotangent function (cotangent). The threshold value is 1 because the long side direction component 100a and the short side direction component 100b become equal when D02B when the inclination angle θ of the display screen long side direction component 100a becomes 45 degrees to the left from the vertical direction to the left direction. It becomes. At this time, the drawing unit 14 (see FIG. 1) included in the portable information terminal 10 displays the first information window 1 (upper information window 1) on a single screen D01 in accordance with the information window display standard D01SS (see FIG. 5). It is good to switch to. The information window display standard D01SS is, for example, “when C01 / D02 is displayed on two screens, the mobile information terminal 10 (display screen long side direction component 100a) is tilted 45 degrees to the left from the vertical direction (inclination angle θ = 45 degrees left) When D02B, the first information window 1 should be displayed as a one-screen display D01 ”. Alternatively, the information window display standard D01SS may be determined so that the second information window 2 (lower information window 2) is enlarged and displayed instead of the first information window 1 (upper information window 1). Good.

  In the case of D02B in which the portable information terminal 10 is further tilted to the left even after the screen display is switched to the single screen display D01, the ratio of the display screen long side direction component 100a to the display screen short side direction component 100b is the mobile information. The inclination angle θ with respect to the vertical direction of the terminal 10 (display screen long side direction component 100a) further decreases from 1 at 45 degrees D02B to the left along the cotangent function, and the inclination angle θ becomes 0 at 90 degrees D01 on the left. In this state, the student of distance learning can browse the information displayed in the first information window 1 selected D01S (see FIG. 5) in detail in a state of being enlarged and displayed by the one-screen display D01.

  When the portable information terminal 10 continues to be tilted to the left from the state in which the portable information terminal 10 rolls over (tilt angle θ = left 90 degrees D01), the ratio of the display screen long side direction component 100a to the display screen short side direction component 100b is the tilt angle. Since θ exceeds 90 degrees to the left (for example, tilt angle θ = 120 degrees left), it may be defined as a negative (minus) value, for example, according to the cotangent function. Further, when the tilt is further leftward and the tilt angle θ is 180 degrees to the left (not shown), the portable information terminal 10 is turned upside down (terminal inverted state). In this case, the top and bottom of the screen display may be switched to perform the initial two-screen display (screen display upright state) D02.

  Alternatively, without changing the top and bottom of the screen display and performing the two-screen display (screen display upright state) D02, the tilt angle θ is 180 degrees to the left (screen display) while the first information window 1 is still displayed. It is also possible to convert the tilt angle θ in the case of continuing to tilt to the left beyond the rollover state) to the rightward tilt angle θ according to the cotangent function (cotangent). That is, for example, the screen display may be switched by converting the tilt angle θ = 210 degrees to the left into the tilt angle θ = 150 degrees to the right. In this case, when the portable information terminal 10 is further tilted to the left, when the tilt angle θ = 270 ° left = 90 ° right, the first information window 1 is displayed on one screen (inverted screen display). As described later in detail, the state (D01) may be switched directly to the one-screen display (screen display upright state) D01 of the second information window 2.

  When switching to the two-screen display D02 by returning the portable information terminal 10 according to the present embodiment from the state tilted leftward (the state where the first information window 1 is displayed on the one-screen display D01). Will be described. The threshold value at the time of D01A for switching from the one-screen display D01 to the two-screen display D02 may be similarly determined by the information window display standard D01SS (see FIG. 5). Also in this case, a predetermined ratio (threshold value) of the gravitational acceleration 100 detected by the acceleration sensor 12 (see FIG. 1) to the display screen short side direction component 100a of the display screen long side direction component 100a is, for example, a portable information terminal. 10 (display screen long side direction component 100a) may be set to 1 when the tilt angle θ from the vertical direction is returned to 45 degrees to the left at D01A. Thus, typically, the first threshold (first angle) for switching from the two-screen display (second display mode) D02 to the one-screen display (first display mode) D01, and one screen The second threshold value (second angle) for switching from the display D01 to the two-screen display D02 is the same value (for example, the same angle or the ratio of the component components) (for example, the inclination angle θ = left as described above) 45 degrees). However, as will be described in detail later, the first threshold (for example, the first angle) and the second threshold (for example, the first angle) are different from each other (for example, different angles or component ratios). It is good also as what is provided as.

  When the portable information terminal 10 according to the present embodiment is returned from the state tilted to the left, the ratio of the display screen long side direction component 100a to the display screen short side direction component 100b is a cotangent function (cotangent). The long side direction component 100a and the short side direction component 100b become equal again at D01A when the inclination angle θ of the display screen long side direction component 100a is returned to 45 degrees to the left from the vertical direction to the left direction. The threshold is 1. At this time, the drawing unit 14 (see FIG. 1) included in the portable information terminal 10 displays the first and second information windows 1 and 2 in the original two-screen display according to the information window display standard D01SS (see FIG. 5). It is good to switch so that it may D02. The information window display standard D01SS is, for example, “When C01 / D01 is displayed on one screen, the portable information terminal 10 (display screen long side direction component 100a) is 45 degrees to the left from the vertical direction (tilt angle θ = left 45). It is preferable that the first and second information windows 1 and 2 are arranged side by side to be displayed on a two-screen display D02 when D01A is returned to a predetermined degree.

  Alternatively, the information window display standard D01SS (see FIG. 5) is defined as, for example, “perform the two-screen display D02 by exchanging the upper and lower positions of the first and second information windows 1 and 2”. Also good. In this way, when switching from the one-screen display D01 to the two-screen display D02, the upper and lower (or left and right) positions of the first and second information windows 1 and 2 are provided so as to be switched continuously. Even when the portable information terminal 10 is tilted in the same direction, different information windows can be alternately selected D01S (see FIG. 5) and enlarged and displayed by the one-screen display D01.

  Even after the screen display is switched to the two-screen display D02, if the portable information terminal 10 is continuously raised (returned) from the left in the vertical direction, the display screen long side direction component 100a corresponds to the display screen short side direction component 100b. The ratio is that the inclination angle θ with respect to the vertical direction of the portable information terminal 10 (display screen long side direction component 100a) increases further from 1 at 45 degrees D01A to the left along the cotangent function. Return to the state before tilting. In this state, the student of distance learning can browse the first and second information windows 1 and 2 in a state where they are displayed side by side by the two-screen display D02.

  Switching of screen display performed by tilting portable information terminal 10 of the present embodiment to the right will be described. Similarly to the threshold value for switching from the two-screen display D02 to the one-screen display D01 performed by tilting the portable information terminal 10 of the present embodiment to the right, for example, the gravitational acceleration 100 according to the information window display standard D01SS (see FIG. 5). The display screen long side direction component 100a may be determined by the ratio of the display screen short side direction component 100b to the display screen short side direction component 100b. In this case as well, as in the case of D02B in which the portable information terminal 10 is tilted to the left, the tilt angle θ from the vertical direction of the portable information terminal 10 (display screen long side direction component 100a) is 45 degrees to the right. It may be set to 1 at the time. The information window display standard D01SS is, for example, “when C01 / D02 is displayed on two screens, the mobile information terminal 10 (display screen long side direction component 100a) is tilted 45 degrees to the right from the vertical direction (inclination angle θ = (45 degrees to the right) When D02C, the second information window 2 should be displayed as a one-screen display D01. "

  Similar to the case of D02B in which the portable information terminal 10 is tilted to the left as described above, the drawing unit 14 (see FIG. 1) provided in the portable information terminal 10 performs the second information window 2 (see FIG. The lower information window 2) can be selected D01S (see FIG. 5) and switched to display one screen D01. Also in this case, the information window display reference D01SS can be arbitrarily determined, or instead of the second information window 2 (lower information window 2), the first information window 1 (upper information window 1). ) May be determined to be enlarged display D01.

  By returning the portable information terminal 10 of the present embodiment from the state tilted to the right (the state in which the second information window 2 is displayed on one screen D01) (tilt angle θ = 90 degrees to the right D01), A case where switching to the two-screen display D02 is performed will be described. The threshold value at the time of D01A for switching from the one-screen display D01 to the two-screen display D02 may be similarly determined by the information window display standard D01SS (see FIG. 5). Also in this case, a predetermined ratio (threshold value) of the gravitational acceleration 100 detected by the acceleration sensor (see FIG. 1) with respect to the display screen long side direction component 100a to the display screen short side direction component 100b is, for example, the portable information terminal 10 The inclination angle θ from the vertical direction of the (display screen long side direction component 100a) may be set to 1 when D01A is returned to the right by 45 degrees. The information window display standard D01SS is, for example, “when C01 / D01 is displayed on one screen, the portable information terminal 10 (display screen long side direction component 100a) is 45 degrees to the right from the vertical direction (inclination angle θ = right 45 It is preferable to determine that the first and second information windows 1 and 2 are arranged as they are in the original state and are displayed on a two-screen display D02. The drawing unit 14 (see FIG. 1) included in the portable information terminal 10 switches the first and second information windows 1 and 2 to the original display according to the information window display standard D01SS and switches them to the two-screen display D02. Good.

  Alternatively, as in the above description, the information window display reference D01SS (see FIG. 5) may, for example, “change the upper and lower positions of the first and second information windows 1 and 2 to display the two-screen display D02. It may be determined that "do it". In this way, when switching from the one-screen display D01 to the two-screen display D02, the upper and lower (or left and right) positions of the first and second information windows 1 and 2 are provided so as to be switched continuously. Even when the portable information terminal 10 is tilted in the same direction, different information windows can be alternately selected D01S (see FIG. 5) and enlarged and displayed by the one-screen display D01.

  Further, as described above, the threshold values D02A, D02B, D02C for switching from the two-screen display D02 to the one-screen display D01 and the threshold value D01A for switching from the one-screen display D01 to the two-screen display D02 are typical. In particular, it should be provided at the same value. However, for example, both thresholds (for example, the angle or the ratio of component force components) may be set to different values due to ergonomic reasons such as the asymmetry of the movable rotation angle of the wrist of the distance learning student Good. For example, according to the information window display standard D01SS (see FIG. 5), when the two-screen display C01 / D02 is displayed, the mobile information terminal 10 (the display screen long side direction component 100a of the gravitational acceleration 100) is 30 left from the vertical direction. The first information window 1 may be displayed as a one-screen display D01 when it is tilted (tilt angle θ = 30 ° left) D02B ”(first threshold). On the other hand, according to the information window display standard D01SS, when the one-screen display C01 / D01 is displayed, the mobile information terminal 10 (display screen long side direction component 100a) is tilted to the left by 50 degrees from the vertical direction. When D01A is returned to (tilt angle θ = 50 degrees to the left), the first and second information windows 1 and 2 are displayed side by side and displayed on two screens D02 ”(second threshold value).

  Thus, by switching between the two-screen display D02 and the one-screen display D01 with different threshold values (for example, the angle or the component force component ratio), for example, the portable information terminal that is displayed on the two-screen display C01 / D02 Angular velocity of rotation 200 of portable information terminal 10 between D02B when tilting 10 from the vertical direction to the left and D01A when returning portable information terminal 10 displayed on one screen C01 / D01 from the left to the original (vertical direction) Can compensate for the difference. For this reason, the student of distance learning D02B tilts the portable information terminal 10 displayed in the two-screen display C01 / D02 from the vertical direction to the left and the portable information terminal 10 displayed in the one-screen display C01 / D01 from the left to the original. The screen display switching operation can be performed with the same operation feeling as in the case of returning to D01A (in the vertical direction). For the same reason, the threshold value for switching the screen display is, for example, when the portable information terminal 10 that has been subjected to the two-screen display C01 / D02 is tilted from the vertical direction to the left D02B or the right D02C, and the one-screen display C01 / It may be determined by different values when D01A is returned (in the vertical direction) from left or right to the portable information terminal 10 that has been D01.

  Alternatively, for example, a threshold for switching from the two-screen display C01 / D02 to the one-screen display C01 / D01 (for example, the angle or the ratio of the component components) (first threshold) and the one-screen display C01 / D01 In order to eliminate the possibility of the occurrence of control instability due to the same value as the threshold value (second threshold value) for switching from 2 to the two-screen display C01 / D02, both threshold values are different. It may be provided in the value. For example, according to the above-described example, when both threshold values are provided 45 degrees to the left from the vertical direction (inclination angle θ = 45 degrees left), for example, on the threshold value (inclination angle θ = 45 degrees left) by chance. When the D02B operation for tilting the portable information terminal 10 is performed so that the angular velocity of the rotation for tilting the portable information terminal 10 is 0, the screen display switching control may be unstable. In this case, the drawing unit 14 (see FIG. 1) tries to switch the screen display from the two-screen display C01 / D02 to the one-screen display C01 / D01, and also from the one-screen display C01 / D01 to the two-screen display C01 / Since the screen display is switched to D02, the screen display switching control may become unstable.

  In order to eliminate the possibility of such a singular point in control, for example, a threshold (first threshold) for switching from the two-screen display C01 / D02 to the one-screen display C01 / D01 is set, for example. It is good to provide at the D02B position inclined from the vertical direction to the left by 50 degrees (inclination angle θ = left 50 degrees). On the other hand, for example, a threshold value (second threshold value) for switching from the one-screen display C01 / D01 to the two-screen display C01 / D02 is set to, for example, 30 degrees from the vertical direction to the left (inclination angle θ = left 30). It may be provided at the position of D01A inclined to a degree. In this way, by providing both threshold values so as to have regions that intersect (overlap) each other, it is possible to eliminate the possibility of control instability that may occur when both threshold values are set to the same value. it can.

  Switching of the screen display of the portable information terminal 10 using the gyro sensor 13 (see FIG. 1) provided in the portable information terminal 10 of the present embodiment will be described. The screen display of the portable information terminal 10 according to the present embodiment can be switched based on the detection of the gravitational acceleration 100 by the acceleration sensor 12 (see FIG. 1), and the liquid crystal provided in the portable information terminal 10 by the gyro sensor 13. It may be provided so that it can also be performed based on the detection of the rotation 200 around the normal line of the display screen 11. Thus, when the portable information terminal 10 is placed on a horizontal surface such as a desk, for example, the gravitational acceleration 100 is applied by the acceleration sensor 12 to the long side direction 11a and / or the short side direction of the liquid crystal display screen 11. Even when it cannot be detected along the line 11b, the screen display can be switched based on the detection of the gyro sensor 13. Such a configuration can be used, for example, when a distance learning student places and operates a relatively large portable information terminal 10 such as a tablet PC (for example, ipad (registered trademark)) on a desk. 13, the rotation 200 of the portable information terminal 10 can be detected and the screen display can be switched.

  The screen display of the portable information terminal 10 according to the present embodiment is switched between detection of the gravitational acceleration 100 by the acceleration sensor 12 (see FIG. 1) and detection of the rotation 200 of the portable information terminal 10 by the gyro sensor 13 (see FIG. 1). It is good to provide according to the detection result which combined. When the portable information terminal 10 is gripped substantially horizontally, the display screen long side direction component component 100a and the display screen short side direction component component 100b of the gravitational acceleration 100 detected by the acceleration sensor 12 are both small values. Become. On the other hand, for example, when the head of a distance learning student is tilted left and right with respect to the vertical direction, the distance learning student is The portable information terminal 10 may be held so that the ten display screens 11 are aligned vertically. In this case, the portable information terminal 10 generates a component component of the gravitational acceleration 100 in the left-right direction as viewed from the distance learning student who is not intended to input to the distance learning student, and this component component is accelerated. The sensor 12 will detect. In such a case, the display screen long-side direction component 100a and the display screen short-side direction component 100b, which are small values when the portable information terminal 10 is held substantially horizontally, are generated in the left-right direction as viewed from the student. The component component of the gravitational acceleration 100 is mixed. In such a case, the acceleration sensor 12 cannot detect the difference between the display screen long side direction component 100a and the display screen short side direction component 100b in a comparable manner (see S01B).

  The drawing unit 14 (see FIG. 1) provided in the portable information terminal 10 of the present embodiment compares the difference between the long side direction component 100a and the short side direction component 100b of the gravitational acceleration 100 by the acceleration sensor 12 (see FIG. 1). In the case of S01B (see FIG. 5) that can no longer be detected, the screen display is switched based on the detection of the gyro sensor (see FIG. 1). For example, the component component of the gravitational acceleration 100 in the normal direction of the liquid crystal display screen 11 detected by the acceleration sensor 12 included in the portable information terminal 10 of the present embodiment is, for example, the information window display reference D01SS (see FIG. 5). S05 (see FIG. 6) may be used to switch the screen display according to the detection result of the gyro sensor 13 when the threshold value exceeds the threshold value determined in FIG. In this case, for example, according to the information window display standard D01SS, “when the component component of the gravitational acceleration 100 in the normal direction of the display screen 11 exceeds 0.8 G, the display screen is changed according to the detection result of the gyro sensor 13. It may be determined that “switch S05 is performed”. Thus, by using the acceleration sensor 12 and the gyro sensor 13 in combination, the detection results can be complemented with each other and the screen display can be switched appropriately.

  In one embodiment, the screen display of the portable information terminal 10 may be switched only in accordance with the detection of the gravitational acceleration 100 by the acceleration sensor 12 (see FIG. 1). In another embodiment, the detection may be performed only by detecting the rotation 200 around the normal axis of the display screen 11 by the gyro sensor 13 (see FIG. 1). By providing in this way, the portable information terminal 10 of the present invention can be configured more simply.

  As described above, switching of the screen display in the portable information terminal 10 according to the present embodiment is performed in the vertical direction on the portable information terminal 10 that has been displayed in two screens C01 / D02 based on one information window display standard D01SS / M01 (see FIG. 5). It has been described that the enlarged display D01 is performed by selecting D01S (see FIG. 5) the first information window 1 when D02B is tilted to the left and D02C when tilting to the right. In this case, the student of the distance learning uses the first information window 1 (for example, the upper information window displayed on the two-screen display D02) and the second information window 2 (for example, the upper direction information window 10) according to the rotation direction in which the portable information terminal 10 is tilted. It is possible to specify by selecting D01S which of the lower information windows) should be enlarged display D01. However, the portable information terminal 10 according to the present embodiment switches the display screen based on another information window display standard D01SS / M02 (see FIG. 5), as will be described in detail below (see FIG. 3). It is good also to do.

  Referring to FIG. 3 showing the switching of the screen display, the screen display switching of portable information terminal 10 of the present embodiment is performed based on another information window display standard D01SS / M02 (see FIG. 5). An example will be described. Switching of the screen display of portable information terminal 10 according to the present embodiment is performed based on another information window display standard D01SS / M02 different from the above-described one information window display standard D01SS / M01 (see FIG. 5). It may be provided. In this case, the selection of switching of the information window display standard D01SS may be performed by a distance learning student, for example, by performing an arbitrary touch input on the portable information terminal 10. In the information window display standard D01SS / M01 described above, the left rotation D02B and the right rotation D02C of the portable information terminal 10 are respectively associated with a specific information window selection D01S (see FIG. 5). Explained. On the other hand, other information window display standards D01SS / M02 may be provided so that information windows are sequentially displayed without questioning the direction of the rotation D02D of the portable information terminal 10.

  In the switching of the screen display of the portable information terminal 10 according to the present embodiment, for example, according to the information window display standard D01SS / M02 (see FIG. 5), the “two-screen display C01 / D02 portable information terminal 10 is It may be determined that the first and second information windows 1 and 2 are alternately enlarged and displayed D01 every D02D tilted to 45 degrees (tilt angle θ = 45 degrees left and right). In this case, for example, in the first rotation D02D in which the portable information terminal 10 displayed in the two-screen display C01 / D02 is rotated from the vertical direction to the right by 45 degrees (inclination angle θ = 45 degrees to the right) or more, One information window 1 (for example, the upper information window in the two-screen display C01 / D02) can be enlarged and displayed C01 / D01. Further, according to the information window display standard D01SS / M02, for example, “the mobile information terminal 10 on which the one-screen display C01 / D01 is displayed is tilted back to 45 degrees from the vertical direction (tilt angle θ = 45 degrees left and right). The first and second information windows 1 and 2 may be arranged side by side and displayed on a two-screen display D02 ”. In this case, for example, when the portable information terminal 10 displayed in the one-screen display C01 / D01 is returned from the tilted state to the right to 45 degrees (tilt angle θ = 45 degrees to the right) from the vertical direction to the right direction. The first and second information windows 1 and 2 can be displayed side by side for two-screen display C01 / D02.

  Further, the second information window 2 is obtained by the second rotation D02D in which the portable information terminal 10 displayed in the two-screen display C01 / D02 is rotated from the vertical direction to the right again by 45 degrees (tilt angle θ = 45 degrees to the right) or more. (For example, the lower information window in the two-screen display C01 / D02) is enlarged and displayed C01 / D01. In this way, the first and second information windows 1 and 2 displayed side by side in the two-screen display C01 / D02 can be provided so as to be alternately enlarged and displayed on the one-screen display C01 / D01. By providing in this way, for example, the screen of the portable information terminal 10 according to the operation D02D in which the distance learning student tilts the portable information terminal 10 held in the dominant hand only in one direction in which the distance learning student can easily tilt. The display can be switched.

  With reference to the flowchart of FIG. 4, switching of the screen display of the portable information terminal 10 of the present embodiment will be described. The portable information terminal 10 according to the present embodiment uses the acceleration sensor 12 (see FIG. 1) or the gyro sensor 13 (see FIG. 1) as the predetermined acceleration 100c or rotation 200c defined in the information window display standard D01SS (see FIGS. 5 and 6). 1) (see FIG. 5 and FIG. 6), the first and second information windows 1 and 2 may be replaced with the third and fourth information windows 3 and 4. . For example, the information window display standard D01SS (see FIG. 5) may be defined as “the information window is replaced when S01A (see FIG. 5) where acceleration of 2 G or more is detected in the horizontal direction”. In this case, the information windows can be replaced by shaking the mobile information terminal 10 strongly in the horizontal direction 100c. Alternatively, for example, according to the information window display standard D01SS (see FIG. 6), it is preferable to define that “the information window is replaced when S01A (see FIG. 6) in which rotation of an angular velocity of 360 degrees / second or more is detected”. . In this case, the information window can be replaced by rotating the portable information terminal 10 quickly 200c.

  Further, the screen display of the portable information terminal 10 according to the present embodiment is switched when there are a large number of information windows (for example, the fifth and sixth information windows 5 and 6) exceeding four as shown in the figure. It is preferable that all information windows are sequentially displayed. After all the information windows have been displayed, it is preferable to return to the first and second information windows 1 and 2 again and repeat the display as shown in the figure. By providing in this way, a student of distance learning who operates the portable information terminal 10 can freely replace a large number of information windows by an easy operation to give the portable information terminal 10 a predetermined acceleration 100c or rotation 200c. In addition, the information windows replaced by the distance learning students can be displayed side by side on the two-screen display D02 or enlarged on the one-screen display D01. For this reason, a distance learning student can refer to a lot of information efficiently and in detail.

  Furthermore, in the same manner as the screen display switching of the portable information terminal 10 according to the present embodiment, the portable information is received in response to an operation instructed by giving a predetermined acceleration 100 c or rotation 200 c to the portable information terminal 10. The display direction C01 / C02 of the two-screen display D02 of the terminal 10 may be switched. For example, when a predetermined acceleration 100c or rotation 200c determined by the information window display standard D01SS (see FIGS. 5 and 6) is detected in the portable information terminal 10, the first display direction (for example, the vertical display) in the two-screen display D02 is detected. The display C01 (see FIG. 2A)) and the second display direction (for example, the display C02 (see FIG. 2B) side by side) may be switched and displayed. Further, a distance learning student selects whether the screen display of the portable information terminal 10 should be switched based on the detection result of the acceleration sensor 12 (see FIG. 1) or the gyro sensor 13 (see FIG. 1). It is good to provide so that it can do. By providing in this way, a distance learning student can display and browse information on the portable information terminal 10 more arbitrarily.

  With reference to the flowchart of FIG. 5, a program for installing in the portable information terminal 10 (see FIG. 2) of the present embodiment and causing the portable information terminal 10 to perform predetermined control and execution processing will be described. The program causes the acceleration sensor 12 (see FIG. 1) to detect the display screen long side direction component 100a (see FIG. 2) and the display screen short side direction component 100b (see FIG. 2) of the gravitational acceleration 100 (see FIG. 2). (S01). When the acceleration sensor 12 cannot detect the difference between the display screen long side direction component 100a and the display screen short side direction component 100b of the gravitational acceleration 100 in comparison with the information window display reference D01SS, the gyro sensor 13 (FIG. 1) may be transferred to a subroutine program (see FIG. 6) that causes the rotation 200 (see FIG. 2) of the portable information terminal 10 to be detected.

  The program also determines whether or not the acceleration detected by the acceleration sensor 12 (see FIG. 1) is a predetermined acceleration 100c (see FIG. 4) determined by the information window display standard D01SS, for example, the microprocessor 20 (see FIG. 1). (Refer to FIG. 1) or the resource of the drawing unit 14 (see FIG. 1). If the acceleration detected by the acceleration sensor 12 is a predetermined acceleration 100c, the first and second information windows that are currently displayed on the liquid crystal display screen 11 (see FIG. 4) are displayed using the drawing unit 14. The information windows 1 and 2 (see FIG. 4) may be replaced with the subsequent third and fourth information windows 3 and 4 (see FIG. 4).

  When the program displays a new information window on the liquid crystal display screen 11 (see FIG. 2) using the drawing unit 14 (see FIG. 1), for example, as described above, the program sets the drawing size of information to be displayed. By referring to the information window, it is preferable to determine whether the information window should be a horizontally long display C01 (see FIG. 2A) or a vertically long display C02 (see FIG. 2B).

  The program also displays a first information window (for example, first information) to be displayed when a new information window is displayed on the liquid crystal display screen 11 (see FIG. 2) using the drawing unit 14 (see FIG. 1). Window 1 (see FIG. 2)) drawing direction (horizontal display C01 (see FIG. 2 (a)) or vertical display C02 (see FIG. 2 (b))) and the gripping direction of the portable information terminal 10 by a distance learning student And D00V for comparison. At this time, the drawing direction (for example, landscape display C01) of the first information window and the gripping direction (for example, the liquid crystal display screen 11 (see FIG. 2A)) of the portable information terminal 10 by the distance learning student are defined as landscape D01 ( 2), the information window may be initially displayed on the liquid crystal display screen 11 using the drawing unit 14 by the one-screen display D01 (S02). .

  The program also draws the first information window (for example, the landscape display C01 (see FIG. 2A)) and the gripping direction (for example, the liquid crystal display screen 11 (see FIG. 2) of the distance learning student). 2) (see FIG. 2A) is inconsistent with the vertically long D02 (see FIG. 2A)), the two-screen display D02 is displayed on the liquid crystal display screen 11 using the drawing unit 14 (see FIG. 1). The information window may be initially displayed (S02).

  The program also displays the acceleration sensor 12 (see FIG. 1) and / or the gyro sensor 13 (see FIG. 1) when the information window is displayed on the liquid crystal display screen 11 (see FIG. 2) using the drawing unit 14 (see FIG. 1). 1), and the detection result of the rotation 200 (see FIG. 2) of the mobile information terminal 10 (see FIG. 2) may be referred to. By referring to the detection result of the gravity acceleration 100 and / or the rotation 200 around the axis in the normal direction of the liquid crystal display screen 11 of the portable information terminal 10, the program should detect and display the attitude of the portable information terminal 10 It is preferable to display the information correctly D01V and D02V by combining the lower side direction of the information window and the lower side direction of the portable information terminal 10.

  The program also refers to the information window display standard D01SS recorded and stored by the recording storage unit 21 (see FIG. 1) when the one-screen display D01 is performed (S02), so that the information window display standard D01SS is displayed. Whether or not the gravitational acceleration 100 for which the screen display should be switched in light of is detected is determined D01A using the resources of the microprocessor 20 (see FIG. 1) or the drawing unit 14 (see FIG. 1). The program uses the drawing unit 14 when it is determined D01A that the gravitational acceleration 100 for switching the screen display is detected in light of the information window display reference D01SS when the single screen display D01 is performed (S02). The screen display may be switched from the one-screen display D01 to the two-screen display D02 (S02).

  On the contrary, when the program is switched from the two-screen display D02 to the one-screen display D01, the program displays any one information window to be enlarged and displayed on the one-screen display D01 based on the information window display standard D01SS. For example, the selection D01S may be determined by using the resources of the microprocessor 20 (see FIG. 1) or the drawing unit 14 (see FIG. 1). The program draws the selected information window D01S based on the information on the gravity acceleration 100 (see FIG. 2) and / or the rotation 200 (see FIG. 2) of the portable information terminal 10 (see FIG. 2) as described above. It is preferable to determine D01V the vertical direction of the image and cause the drawing unit 14 to display one screen D01 (S02).

  The program also terminates the program without making a determination in the second display switching determination D01A and D02A after performing the display switching determination D01A and D02A between the one-screen display D01 and the two-screen display D02 once. You should do it. The number of determinations of the display switching determinations D01A and D02A may be counted by using a flag, for example. By providing in this way, the program can quickly execute a series of processes without looping. While the distance learning student is using the portable information terminal 10 (see FIG. 2), by continuously executing the program that performs the series of execution processes, the attitude of the portable information terminal 10 is monitored. It is possible to switch the display screen by capturing a screen display switching instruction (rotation operation of the portable information terminal 10) by a distance learning student.

  With reference to the flowchart of FIG. 6, the program for installing in the portable information terminal 10 (refer FIG. 2) of this Embodiment and making the portable information terminal 10 perform predetermined control and an execution process is demonstrated. The program can be used as a subroutine program of the program shown in FIG. 5 as described above, and the rotation 200 (see FIG. 2) of the portable information terminal 10 (see FIG. 2) can be performed only by the gyro sensor 13 (see FIG. 1). In the embodiment to detect, it can use similarly to the program shown in FIG. 5 as an independent control program. The program shown in FIG. 6 has substantially the same configuration as the program shown in FIG. 5, but the program shown in FIG. 5 responds to the detection of the gravitational acceleration 100 (see FIG. 2) by the acceleration sensor 12 (see FIG. 1). However, the program shown in FIG. 6 differs in that the processing is performed in accordance with the detection of the rotation 200 by the gyro sensor 13.

  The program causes the gyro sensor 13 (see FIG. 1) to detect the rotation 200 (see FIG. 2) around the normal axis of the liquid crystal display screen 11 (see FIG. 2) of the portable information terminal 10 (see FIG. 2). 5 is different from the configuration in which the program shown in FIG. 5 causes the acceleration sensor 12 (see FIG. 1) to detect the gravitational acceleration 100 (see FIG. 2) for processing. Specifically, a process for detecting the rotation 200 by the gyro sensor 13 (S04), a process for detecting the predetermined rotation 200c (see FIG. 4) (S04A), and the one-screen display D01 or the two-screen display D02 based on the rotation 200. The process (S05) to be performed is different from the process for performing the screen display switching determinations D01R and D02R based on the rotation 200.

  With reference to FIG. 7, a method for performing distance learning for a distance learning student who operates portable information terminal 10 using portable information terminal 10 of the present embodiment will be described. In FIG. 7 (a), an image 300 of the instructor performing distance learning, which is the first information displayed in the first information window 1, is displayed on the liquid crystal display screen 11 of the portable information terminal 10 and the second information window 2. The video of the resume 400 of the distance learning content, which is the second information that complements the first information, and summarizes the main points of the distance learning content, is displayed side by side by the two-screen display D02. The remote education content resume 400 that is the second information displayed in the second information window 2 complements the video 300 of the instructor who performs the distance education that is the first information displayed in the first information window 1. The summary information may be summary information that summarizes the contents of the distance learning, or may be supplementary information that is composed of sentences or charts for supplementarily explaining the details of the distance learning contents.

  The ratio of the lengths of the sides of the illustrated rectangular first information window 1 and rectangular second information window 2 may be, for example, long side: short side = √2: 1. With this configuration, it is not necessary to change the aspect ratio of the information window between when two information windows are arranged vertically and displayed on the two screens D02, and when one information window is enlarged and displayed D01. Alternatively, when the information window is enlarged and displayed by the one-screen display D01, the ratio of the long side / short side may be displayed larger than √2. In this case, when the information window is enlarged and displayed D01, it is somewhat horizontally long, but characters and the like are displayed in a large size as in the wide screen display of the TV, and can be displayed easily. Alternatively, the aspect ratio of the information windows 1 and 2 may be displayed as a longer side: a shorter side = 4: 3, more standardly.

  The reason why the first and second information windows 1 and 2 shown in FIG. 7A are displayed in the horizontally long C01 is because the human eyes are separated from each other in the left and right directions and have their respective fields of view. This is because the display screen having a horizontally long C01 in the direction is generally easily visible. On the other hand, the liquid crystal display screen 11 of the general portable information terminal 10 is often provided in a vertically long rectangle as shown in FIG. 7A in order to improve portability. According to the portable information terminal 10 of the present invention, the liquid crystal display screen 11 of the portable information terminal 10 that is typically provided in a vertically long rectangle in favor of portability has a first and second horizontally long C01 that is easy for a human to visually recognize. When the two information windows 1 and 2 are displayed on the two screens D02, the information can be displayed as large as possible. Further, when either the first or second information window designated by the distance learning student is enlarged and displayed D01, the person on the liquid crystal display screen 11 of the portable information terminal 10 that has been rolled over D02A (see FIG. 2) is displayed. Can be further enlarged and displayed by a one-screen display D01.

  In the portable information terminal 10 of the present embodiment shown in FIG. 7A, for example, information such as images and figures that are easy to understand mainly by the function of the right brain is displayed in the first horizontally long information window 1. In the information window 2 of the second horizontally long C01, character information that can be understood mainly by the function of the left brain is displayed so that the entire information can be displayed particularly easily. Alternatively, qualitative information is displayed in the first horizontally long information window 1 and quantitative information is displayed in the second horizontally long information window 2 so that the entire information can be easily understood. It should be displayed. Or while displaying the 1st comparison information in the 1st information window 1 and displaying the 2nd comparison information in the 2nd information window 2, the difference between both can be grasped exactly. As described above, it is preferable to display the information in a particularly easy-to-understand manner.

  In the portable information terminal 10 of the present embodiment shown in FIG. 7A, the first information window 1 displays a video 300 that shows a distance education instructor performing distance education as the first information. ing. For this reason, distance learning students can comprehensively learn the contents of lectures conducted by distance learning instructors by grasping the instructor's thoughts, feelings and intentions from the expressions, gestures and gestures of the instructors. The second information window 2 displays a resume 400 that summarizes the main points of the distance learning contents, which are second information that complements the first information, and that is shown in characters and diagrams. Therefore, distance learning students can learn the main points of distance learning accurately and intensively. In addition, a distance learning student presents a video 300 (first information) of a distance learning instructor presenting comprehensive information displayed in the first information window 1 and an aggregation displayed in the second information window 2. It is possible to perform learning particularly efficiently by simultaneously comparing and referring to a resume image 400 (second information that complements the first information) of the distance learning content that presents typical information.

  Further, as described above, as shown in FIGS. 7B and 7C, only the information displayed in one of the first and second information windows 1 and 2 is displayed by the distance learning student. When it is desired to verify in more detail, a desired information window can be easily enlarged and viewed D01 by browsing the portable information terminal 10 by rotating it by 90 degrees D02A in either direction (see FIG. 2). The distance learning student visually recognizes the video 300 (first information) of the distance learning instructor by rotating one hand holding the portable information terminal 10 90 degrees to the left, for example, D02B (see FIG. 2A). It is possible to browse in detail by enlarging D01 greatly on the rectangular display screen 11 of the horizontally long C01 that is easy to perform (see FIG. 7B). On the other hand, a remote education student D02C (see FIG. 2A) that rotates one hand holding the portable information terminal 10 90 degrees clockwise, for example, can receive a video of the resume 400 of the distance education content (first information). Can be viewed in detail with a large enlargement D01 on the rectangular display screen 11 having a horizontally long C01 that is easily visible (see FIG. 7C).

  Information displayed in the first and second information windows 1 and 2 of the horizontally long C01 that is particularly easy to visually recognize by a specially easy operation of rotating one hand holding the portable information terminal 10 by a distance learning student Can be displayed side by side by the two-screen display D02 (see FIG. 7A). Further, the one-screen display D01 (see FIG. 7B) for displaying the details of the first horizontally long information window 1 in an enlarged manner and the details of the second horizontally long information window 2 in an enlarged manner are displayed. Information can be browsed in detail by freely switching between the one-screen display D01 (see FIG. 7C).

  With reference to another example of the screen display of FIG. 8, in the one-screen display D01 in the portable information terminal 10 of the present embodiment, one information window that is enlarged and other information windows that are reduced and displayed 1w and 2w And will be described. FIG. 8B shows, for example, an enlarged display of the first information window 1 by the one-screen display D01 in response to a D02B operation in which a distance learning student tilts (rotates) the portable information terminal 10 to the left. Shows the state. In the enlarged display (one-screen display) D01 of the first information window 1 shown in FIG. 8B, the selection D01S (see FIG. 5) is selected when D02A (see FIG. 5) switches from the two-screen display D02 to the one-screen display D01. The other information window (second information window 2) that has not been displayed is reduced and displayed 2w so as to overlap the first information window 1.

  By performing the screen display in this manner, the student of distance education can select the first information window 1 by selecting D01S (see FIG. 5) and refer to the enlarged display D01 to display the second information window 2. The displayed information can be grasped by referring to the reduced display 2w. Therefore, when the information in the second information window 2 is updated, the distance learning student updates the information (second information) in the second information window 2 displayed in the reduced display 2w. The change can be grasped. When the interest of the distance learning student is transferred to the contents of the second information window 2, the distance learning student can refer to the second information window 2 by the two-screen display D02 (see FIG. 8A) as needed. Can be displayed in large size for reference. Furthermore, the student of distance learning can refer to the second information window as an enlarged display D01 by tilting (rotating) the portable information terminal 10 in the right direction (see FIG. 8C).

  Note that, as in the example of the screen display of the portable information terminal 10 of the present embodiment shown in FIG. 8C, the second information window 2 that is enlarged display D01 and the first information window 1 that is reduced display 1w. May be displayed side by side. By displaying in this way, the information in the first information window 2 displayed in the reduced display 1w is not hidden from the information in the second information window 2 displayed in the enlarged display D01. The information can be suitably enlarged and displayed D01. In this case, also in the one-screen display D01 of the second information window 2, the first information window 1 and the second information window 2 are displayed side by side in a direction different from the direction displayed in the two-screen display D02. However, the display method of the information window shown in FIG. 8C essentially enlarges and displays the second information window 2 in the same manner as the display method of the information window shown in FIG. It is included in the spirit of the present invention.
