  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram illustrating a configuration example of a mobile device according to the first embodiment.

  The mobile device 11 is a processing device realized by, for example, a mobile phone. The portable device 11 includes an execution unit 11A, a non-contact detection unit 11B, and a control unit 11C. The control unit 11 </ b> C includes a CPU (Central Processing Unit) 12 and a memory unit 13.

  Execution unit 11A can generally be referred to as execution means.

  The execution unit 11 </ b> A executes a predetermined operation (display operation in the present embodiment) among the operations of the mobile device 11. The execution unit 11A includes an input control unit 14, an operation key 15, a display control unit 18, a display 19, a communication processing unit 20, a wireless unit 21, and a bus 22.

  The operation key 15 is a device operated by the user of the portable device 11.

  The input control unit 14 receives an instruction input from a user using the operation keys 15.

  The radio unit 21 communicates with an external communication device using radio.

  The communication processing unit 20 performs predetermined processing on data for the wireless unit 21 to communicate.

  Display 19 can be generally referred to as display means.

  The display 19 is a display device that performs a display operation as a predetermined operation. The display 19 is disposed on the front surface of the mobile device 11 and is realized by, for example, a liquid crystal panel or an organic EL (Electro Luminescence) device.

  The display control unit 18 controls an image displayed on the display 19 in accordance with an instruction from the CPU 12. For example, the display control unit 18 switches the display state of the display 19 in accordance with an instruction from the CPU 12. In addition, the display control unit 18 scrolls, enlarges, or reduces the display on the display 19 in accordance with an instruction from the CPU 12.

  Non-contact detection unit 11B can be generally referred to as detection means.

  The non-contact detection unit 11 </ b> B detects a detection target that is a part of the user of the mobile device 11 in a non-contact manner. The non-contact detection unit 11B detects the detection object in a non-contact manner and outputs a detection result.

  In the present embodiment, the non-contact detection unit 11B outputs a detection signal whose signal level changes according to the distance from the portable device 11 to the detection target to the control unit 11C as a detection result. The non-contact detection unit 11B includes a sensor control unit 16 and proximity sensors 171 to 173.

  Proximity sensors 171-173 can generally be referred to as a plurality of detection means.

  Each of the proximity sensors 171 to 173 detects the user's face as a detection target in a non-contact manner, and outputs a detection signal to the sensor control unit 16.

  In this embodiment, as the proximity sensors 171 to 173, a capacitance sensor that is a capacitance type proximity sensor is used. Each of the proximity sensors 171 to 173 detects a change in the relative distance between the proximity sensor itself and the user's face in a non-contact manner. Therefore, the proximity sensors 171 to 173 output a detection signal having a larger detection value (signal level) as the distance from the user's face is shorter.

  The proximity sensors 171 to 173 are realized by, for example, JIS standard proximity switches. The proximity switch of the JIS standard is a proximity switch that conforms to the low switching device and processing device, the fifth part control circuit device and switching device, and the second node proximity switch (JIS C 8201-5-2). This proximity switch of the JIS standard is planned in conformity with the non-contact type position detection switch of the international standard IEC 60947-5-2. The proximity sensors 171 to 173 are not limited to JIS standard proximity switches, and may be any sensors that can detect a detection target in a non-contact manner.

  In the present embodiment, it is desirable that the proximity sensors 171 to 173 are arranged so that all the proximity sensors 171 to 173 do not line up on one straight line.

  FIG. 2 is a diagram illustrating an arrangement example of the proximity sensors 171 to 173 provided in the portable device 11.

  The proximity sensors 171 to 173 are arranged on the outer peripheral portion of the display 19 provided on the front surface of the mobile device 11.

  The proximity sensor 171 is disposed at the center of the upper portion of the display 19. The proximity sensor 172 is disposed near the center of the left side portion of the display 19. The proximity sensor 173 is disposed at the same height as the proximity sensor 172 in the right portion of the display 19.

  The user of the portable device 11 visually recognizes information displayed on the display 19 while operating the operation keys 15.

  Returning to FIG. 1, the sensor control unit 16 instructs the proximity sensors 171 to 173 to execute or stop the detection. Moreover, the sensor control part 16 receives each detection result from the proximity sensors 171-173 for every predetermined period. The sensor control part 16 will output each detection signal to CPU12, if each detection signal is received from the proximity sensors 171-173. Note that the sensor control unit 16 may output the detection signal to the CPU 12 when the level of the detection signal exceeds a predetermined output threshold.

  Control unit 11C can be generally referred to as control means.

  11 C of control parts control the display operation of the display 19 based on the combination of the detection result in the different timing of the non-contact detection part 11B. The control unit 11C switches the display on the display 19, for example, based on combinations of detection results at different timings of the non-contact detection unit 11B.

  Specifically, the control unit 11C determines whether the detection target is approaching or leaving the portable device 11 according to the level of the detection signal. In this case, when the control unit 11C receives the detection signal from the non-contact detection unit 11B, the detection target is detected when the level of the detection signal is higher than a predetermined signal threshold with respect to the level of the detection signal received immediately before. Is determined to have approached. On the other hand, when the level of the detection signal is smaller than a predetermined signal threshold with respect to the level of the detection signal received immediately before, the control unit 11C determines that the detection target has left.

  Then, for example, the control unit 11C instructs the execution unit 11A to switch the display 19 when the detection target approaches, and cancels the display switching when the detection target leaves.

  In addition, the control unit 11C performs non-contact detection on a detection result indicating an operation in which the level of the detection signal becomes smaller than a second detection threshold that is smaller than the first detection threshold by a predetermined variation amount after exceeding the first detection threshold. When a predetermined number of times is received from the unit 11B within a predetermined time, the speed of scrolling the display 19 may be increased. For this reason, when the user repeats a predetermined number of movements after moving the face closer to the portable device 11, scrolling of the display image displayed on the display 19 becomes faster. In this case, the first detection threshold, the second detection threshold, and the predetermined fluctuation amount are stored in the memory unit 13 in advance.

  In the present embodiment, the control unit 11 </ b> C performs display processing on the display image displayed on the display 19 based on the combination of detection signal patterns output from the proximity sensors 171 to 173. For example, the control unit 11C performs display processing for scrolling the display image on the display 19 up and down or left and right, and display processing for enlarging or reducing the display image, based on a combination of detection signals output from the proximity sensors 171 to 173. Do.

  The memory unit 13 includes, for each of a plurality of display processes, identification information for identifying the display process and specific information for specifying a combination of detection signal patterns output from the proximity sensors 171 to 173. It is stored in association. The specific information is used to specify the movement of the user's face. For example, in the memory unit 13, identification information indicating display processing for enlarging a display image, and specification indicating each detection signal pattern when the proximity sensors 171 to 173 detect the movement of the user to bring the face closer to the display 19. Information is stored.

  The memory unit 13 stores a control program executed by the CPU 12. Further, the memory unit 13 stores data that is temporarily required when the CPU 12 executes arithmetic processing or the like. The memory unit 13 is a computer-readable recording medium.

  The CPU 12 is a central processing unit that controls each of the memory unit 13, the input control unit 14, the sensor control unit 16, the display control unit 18, and the communication processing unit 20 via the bus 22.

  In the present embodiment, the CPU 12 scrolls, enlarges, or reduces the display 19 based on a combination of patterns of detection signals specified by specific information in the memory unit 13.

  The CPU 12 collates each detection signal received from the sensor control unit 16 with each detection signal pattern indicated by the specific information in the memory unit 13 to identify the movement of the user's face relative to the display 19. For example, the CPU 12 calculates the correlation degree indicating the correlation between each detection signal received from the sensor control unit 16 and the pattern of each detection signal indicated in the specific information in the memory unit 13 for each specific information. When the value exceeds a predetermined correlation threshold, identification information associated with the specific information is specified. The CPU 12 executes a display process identified by the identification information.

  The CPU 12 is a computer that controls each of the execution unit 11A and the non-contact detection unit 11B according to a program stored in the memory unit 13.

  Next, the operation of the mobile device 11 will be described.

  FIG. 3 is a diagram illustrating a state in which the user 31 moves the face of the user 31 from the right to the left with respect to the portable device 11 while viewing the display 19 in front.

  FIG. 4 is a diagram showing changes in the detection signals output from the proximity sensors 171 to 173 when the face of the user 31 moves as shown in FIG. FIG. 4 a shows the change in the detection signal output from the proximity sensor 171. FIG. 4 b shows the change in the detection signal output from the proximity sensor 172. FIG. 4 c shows the change in the detection signal output from the proximity sensor 173.

  When the face of the user 31 is on the right side of the mobile terminal 11, the detection value of the detection signal output from the proximity sensor 173 that is closest to the face of the user 31 is the largest.

  When the face of the user 31 moves to the left and the face of the user 31 moves to the center front of the mobile device 11, the detection value output from the proximity sensor 173 decreases, and the distance from the face of the user 31 is increased. The detection value output from the nearest proximity sensor 171 is the largest. That is, the proximity sensor 173 outputs a detection signal, and then the proximity sensor 172 outputs a detection signal.

  When the face of the user 31 further moves to the left and the face of the user 31 moves to the left of the portable device 11, the detection value output from the proximity sensor 172 that is closest to the face of the user 31 is the largest. The detection value output from the proximity sensor 173 that increases and is the farthest from the face of the user 31 is the smallest value among the proximity sensors 171 to 173. That is, after the proximity sensor 172 outputs the detection signal, the proximity sensor 172 outputs the detection signal.

  In FIG. 4, the change of each detection signal when the face of the user 31 moves from the right to the left with respect to the display 19 is shown in time series, but the face of the user 31 moves from the left to the right. Each detection signal in this case shows a pattern opposite to the pattern shown in FIG. That is, each of the detection signals output from the proximity sensors 171 to 173 has the maximum detection value in the order of the proximity sensor 172, the proximity sensor 171, and the proximity sensor 173.

  FIG. 5 is a diagram illustrating a state in which the user 31 moves the face of the user 31 from below to the portable device 11 while looking at the display 19 in front.

  FIG. 6 is a diagram showing changes in the detection signals output from the proximity sensors 171 to 173 when the face of the user 31 moves as shown in FIG. FIG. 6 a shows a change in the detection signal output from the proximity sensor 171. FIG. 6 b shows the change in the detection signal output from the proximity sensor 172. FIG. 6 c shows the change in the detection signal output from the proximity sensor 173.

  When the face of the user 31 is on the lower side of the mobile terminal 11, the detection values of the respective detection signals output from the proximity sensors 172 and 173 that are closest to the face of the user 31 are the largest.

  When the face of the user 31 moves upward and the face of the user 31 moves to the upper front of the portable device 11, the detection values output from the proximity sensors 172 and 173 decrease, and the face of the user 31 The detected value output from the proximity sensor 171 having the shortest distance is the largest. That is, the proximity sensors 172 and 173 each output a detection signal, and then the proximity sensor 171 outputs a detection signal.

  In FIG. 6, the change of each detection signal when the face of the user 31 moves from the bottom to the top with respect to the display 19 is shown in time series, but the face of the user 31 moves from the top to the bottom. Each detection signal in this case shows a pattern opposite to the pattern shown in FIG. That is, when the face of the user 31 is on the top, the detection value output from the proximity sensor 171 is the largest, and output from the proximity sensors 172 and 173 as the face of the user 31 moves from top to bottom. Each detected value increases equally with each other.

  FIG. 7 is a diagram illustrating a state in which the user 31 brings the face of the user 31 closer to the portable device 11 while viewing the display 19 in front.

  FIG. 8 is a diagram illustrating changes in detection signals output from the proximity sensors 171 to 173 when the face of the user 31 approaches as shown in FIG. FIG. 8 shows changes in each detection signal when the face of the user 31 approaches in the center of the proximity sensors 171 to 173. FIG. 8 a shows the change in the detection signal output from the proximity sensor 171. FIG. 8 b shows the change in the detection signal output from the proximity sensor 172. FIG. 8 c shows the change in the detection signal output from the proximity sensor 173.

  As the face of the user 31 approaches the mobile terminal 11, the detection value of the detection signal output from the proximity sensors 171 to 173 increases. That is, the proximity sensors 171 to 173 output detection signals at the same timing. Thereafter, the proximity sensors 171 to 173 present detection signals at the same timing.

  In FIG. 8, the change of the detection signal when the face of the user 31 is brought closer to the portable device 11 is shown in time series, but the detection signal when the face of the user 31 is moved away is shown in FIG. The reverse pattern is shown. That is, the detection value output from each of the proximity sensors 171 to 173 decreases as the distance between the face of the user 31 and the mobile device 11 increases.

  As shown in FIGS. 4 to 8, when the face of the user 31 moves in the vertical, horizontal, and perspective directions with respect to the display 19, the proximity sensors 171 to 173 output for each movement direction. The detection value of each detection signal changes in a specific pattern.

  For this reason, in the portable device 11, specific information indicating the pattern of each detection signal for each moving direction is stored in the memory unit 13 in advance, and the CPU 12 stores each detection signal output from the proximity sensors 171 to 173 and the memory. The direction of movement of the user's face is specified using the pattern of each detection signal indicated in the specific information in the unit 13.

  For example, the memory unit 13 stores specific information indicating the order of the proximity sensors 171 to 173 in which the level of each detection signal exceeds a specific threshold within a predetermined period. The CPU 12 specifies the moving direction of the user's face relative to the display 19 based on the order in which the levels of the detection signals output from the proximity sensors 171 to 173 exceed the specific threshold. That is, when the proximity sensors 171 to 173 detect the user's face in order, the CPU 12 controls the display operation of the display 19 according to the order in which the proximity sensors 171 to 173 detect the user's face.

  In the present embodiment, the proximity sensors 171 to 173 have described an example in which the user's face is detected as a detection target in a non-contact manner, but the detection target is not limited to the user's face. For example, the proximity sensor 171 to 173 may detect the user's hand in a non-contact manner.

  When detecting the user's hand as a detection target, the memory unit 13 stores specific information for specifying a detection signal pattern indicating a time-series change of the detection value for each movement direction of the hand with respect to the display screen. The CPU 12 specifies the moving direction of the hand with respect to the portable device 11 using the specific information in the memory unit 13 and the detection signals output from the proximity sensors 171 to 173. CPU12 will set the display area of a display image according to the movement direction, if the movement direction of a user's hand is specified.

  For example, the CPU 12 executes display processing for rotating the display image to the right or left, or display processing for scrolling the display image in an oblique direction according to the moving direction of the hand with respect to the display 19. Or CPU12 will perform the function displayed on the display 19, if the pattern of each detection signal when a user's hand moves to right and left is received from the proximity sensors 171-173 repeatedly predetermined times. Further, when the CPU 12 repeatedly receives the detection signal patterns when the user's hand moves up and down from the proximity sensors 171 to 173 a predetermined number of times, the CPU 12 cancels the execution of the function displayed on the display 19.

  FIG. 9 is a flowchart illustrating a processing procedure example of the processing method of the mobile device 11.

  In FIG. 9, in the memory unit 13, specific information for specifying the movement of the detection target object in the right direction with respect to the display 19 and the specific information for specifying the movement of the detection target object in the left direction of the display 19 are specified. Specific information for identifying the movement of the detection object moving upward with respect to the display 19, identification information for specifying the movement of the detection object moving downward with respect to the display 19, and the detection object of the display 19 Specific information specifying the movement moving in the direction approaching the image and identification information specifying the movement moving the detection object in the direction moving away from the display 19 are associated with identification information indicating different display processes. Is remembered.

  In FIG. 9, the power is supplied to the mobile terminal 11 by the user, and an image such as a map or a photograph is displayed on the display 19. The user is browsing the image displayed on the display 19.

  First, in the portable device 11, the proximity sensors 171 to 173 detect the detection target object on the front surface of the portable device 11 in a non-contact manner (step S901). The portable device 11 records the pattern of each detection signal output from the proximity sensors 171 to 173 in the memory unit 13 (step S902).

  Thereafter, the CPU 12 analyzes the pattern of each detection signal recorded in the memory unit 13 and the pattern of each detection signal indicated in the specific information in the memory unit 13 for each specific information and stores the pattern in the memory unit 13. It is then determined whether there is specific information corresponding to the pattern of each detected signal (step S903).

  When the CPU 12 specifies the specific information for specifying the movement of the detection target in the right direction (step S904), the display on the display 19 is performed as a display process identified by the identification information associated with the specific information. Display processing for scrolling the image to the right is executed (step S905).

  CPU12 specifies the specific information which specifies the movement to which a detection target object moves to the left direction (step S906), As a display process identified by the identification information matched with the specific information, display of the display 19 is performed. Display processing for scrolling the image to the left is executed (step S907).

  Further, when the CPU 12 specifies the specific information for specifying the movement of the detection target to move upward (step S908), the display 19 is displayed as the display process identified by the identification information associated with the specific information. The display process for scrolling the display image upward is executed (step S909).

  Thereafter, when the CPU 12 specifies specific information for specifying the movement of the detection target to move downward (step S910), the display 19 is displayed as the display process identified by the identification information associated with the specific information. Display processing for scrolling the display image in the downward direction is executed (step S911).

  Further, when the CPU 12 specifies the specific information for specifying the movement of the detection target (step S912), the display image of the display 19 is displayed as the display processing identified by the identification information associated with the specific information. A display process for enlarging the image is executed (step S913).

  Further, when the CPU 12 specifies the specific information for specifying the movement of the detection target object (step S914), the display image on the display 19 is displayed as the display process identified by the identification information associated with the specific information. The display process to reduce is executed (step S915).

  And when the specific information applicable to each detection signal recorded on the memory part 13 does not exist, the portable terminal 11 returns to step S901, and repeats the process of step S901 thru | or S915.

  According to 1st Embodiment, the non-contact detection part 11B detects a user's face as a detection target object non-contact. The non-contact detection unit 11B is composed of a capacitance sensor.

  For this reason, the portable device 11 can detect the user's face in a non-contact manner without performing a complicated process of detecting the user's face in the image based on the image captured by the camera. It becomes.

  Further, in the first embodiment, the execution unit 11A has a display 19 that executes a display operation as a predetermined operation, and the control unit 11C has a pattern of detection signals that are detection results at different timings of the non-contact detection unit 11B. The display operation of the display 19 is controlled based on the combination. For example, the control unit 11 </ b> C performs scrolling and enlargement or reduction of the display 19 as the display operation of the display 19.

  For this reason, the portable device 11 specifies the display operation of the display 19 for each combination of detection signal patterns at different timings, and executes the specified display operation. Therefore, in the mobile device 11, the user can operate the mobile device 11 in a non-contact manner without performing complicated processing.

  In addition, the mobile device 11 not only determines whether the detection object is approaching or leaving according to the level of the detection signal, but can also identify the repetitive operation of the detection object using a combination of detection signal patterns. It is also possible to control display operations of three or more different displays 19. For this reason, the mobile device 11 can increase the number of display operations that can be performed in accordance with the number of combinations of detection signal patterns.

  In the first embodiment, the non-contact detection unit 11B is provided with three proximity sensors 171 to 173, and each of the proximity sensors 171 to 173 detects a user's face in a non-contact manner. The control unit 11C scrolls, enlarges, or reduces the display on the display 19 based on the combination of the detection signal patterns output from the proximity sensors 171 to 173.

  The portable device 11 also uses the three proximity sensors 171 to 173 to specify the vertical and horizontal movements of the user's face relative to the display 19. Therefore, the display 19 can be scrolled in the vertical direction according to the vertical movement of the user's face, and the user can adjust the image displayed on the display 19 according to the movement of the user's face. It becomes possible to operate.

  In the first embodiment, the example in which the mobile device 11 executes the operation of the mobile device 11 using the three proximity sensors 171 to 173 has been described. However, the mobile device 11 uses two proximity sensors. Alternatively, four or more proximity sensors may be used. In the portable device 11, it is also possible to increase the number of proximity directions of the detection target object by increasing the number of proximity sensors. In general, one proximity sensor detects movement in the perspective direction, two proximity sensors change in one direction, three proximity sensors change in two directions, four proximity sensors change in three directions A change in motion is detected.

  FIG. 10 is a block diagram illustrating a configuration example of the mobile device 31 according to the second embodiment. In FIG. 10, the same components as those of the mobile device 11 are denoted by the same reference numerals.

  The portable device 31 has basically the same configuration as the portable device 11 except for the non-contact detection unit 31B.

  The non-contact detection unit 31B corresponds to the non-contact detection unit 11B of the first embodiment.

  The non-contact detection unit 31B detects the detection object in a non-contact manner. While detecting the detection target object in a non-contact manner, the non-contact detection unit 31B outputs a detection signal indicating the distance from the portable device 31 to the detection target object as a detection result. The non-contact detection unit 31B includes a sensor control unit 16 and proximity sensors 371 to 373.

  An infrared sensor is used as the proximity sensors 371 to 373. The infrared sensor is an infrared reflective proximity sensor. The proximity sensors 371 to 373, for example, emit pulsed light, measure the time from when the pulsed light is emitted until the pulsed light reflected by the detection target is received, and use the measured time for proximity. The distance from the sensor to the detection target is obtained. The proximity sensors 371 to 373 output a detection signal indicating the obtained distance.

  The control unit 31C corresponds to the control unit 11C of the first embodiment.

  The control unit 31C controls the display operation of the display 19 based on a combination of detection signal patterns output from the proximity sensors 371 to 373.

  For example, the control unit 31C changes the page displayed on the display 19 when the user's face moves in the left-right direction based on the combination of detection signal patterns output from the proximity sensors 371 to 373. If the user's face moves up and down, the display image is scrolled. When scrolling the display image, the control unit 31C may change the scrolling speed for each change amount of the detection signal per unit time.

  Further, the control unit 31C instructs the execution of the function displayed on the display 19 when the user's face approaches based on the combination of the detection signal patterns, and when the user's face moves away. The function displayed on the display 19 is canceled.

  According to 2nd Embodiment, the portable apparatus 31 has the non-contact detection part 31B implement | achieved by the infrared sensor. The control unit 31C controls the display operation of the display 19 based on a combination of detection signal patterns output from the proximity sensors 371 to 373.

  For this reason, the non-contact detection unit 31B can measure the distance from the portable device 31 to the detection target with higher accuracy than the capacitance-type non-contact detection unit 11B. Therefore, the portable device 31 can accurately specify the moving direction of the detection target with respect to the display 19 and can accurately control the display operation of the display 19 according to the movement of the user.

  In the second embodiment, the example in which the mobile device 31 controls the operation of the mobile device 31 using the three proximity sensors 371 to 373 has been described. However, the mobile device 31 uses two proximity sensors. Alternatively, four or more proximity sensors may be used. In the portable device 31, it is possible to increase the number of infrared reflection type proximity sensors to increase the number of movement directions in which the detection target can be specified. In general, one proximity sensor detects a change in movement in one direction, two proximity sensors change in two directions, three proximity sensors detect a movement in three directions, and four proximity sensors. Then, changes in movement in three directions are detected with higher accuracy than in the case of three proximity sensors.

  In each embodiment, an example in which a proximity sensor is used as the non-contact detection unit has been described. However, a camera that images a detection target may be used. In this case, the detection target in the image is specified based on the image captured by the camera, and the movement of the detection target is detected. Alternatively, a detection system including a transmitter that transmits radio waves and a receiver that receives the radio waves may be used as the non-contact detection unit. In this case, the transmitter is attached to the user's finger, the receiver is provided in the portable device, and the distance from the portable device to the user's finger is measured using the oscillator and the receiver, and according to the distance. User movement is detected.

In each embodiment described above, the illustrated configuration is merely an example, and the present invention is not limited to the configuration.
