BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, an electronic blackboard device according to an embodiment of the present invention will be described in detail with reference to the drawings. Note that components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiments.

FIG. 1 is a block configuration diagram of an electronic blackboard device according to an embodiment of the present invention. The electronic blackboard device 100 mainly includes a writing screen 10, writing position sensing means 20, writing screen moving means 30, control means 40, and the like.

[0010] The writing screen 10 is a screen on which characters and figures are to be input by hand, and in the case of a display device with a touch panel, it indicates the display screen of the display device including the touch panel. In addition, when writing directly with a marker or chalk, the whiteboard refers to the board surface of the blackboard.

[0011] The writing position sensing means 20 is a means for sensing the input position where the operator is writing on the writing screen. In the case of a display device with a touch panel, the writing position sensing means 20 refers to the touch panel. In the case of a whiteboard or blackboard, it refers to a sensor using a piezoelectric element or an infrared element. The touch panel is detachable from the display frame and is equipped with a position sensor including an optical sensor such as an infrared ray or a contact sensor such as a piezoelectric element arranged in a sheet shape, and is brought close to or in contact with the display surface. Detects the position of the pen tip and finger.

[0012] Next, the writing screen moving means 30 is a means for appropriately moving the position of the writing screen 10, that is, the input position where the operator writes, and in the case of a display device with a touch panel, This refers to control software that moves characters, figures, and backgrounds electronically. In other words, without physical movement of the display screen of the display device, Only the image displayed on the display moves. On the other hand, in the case of a whiteboard or blackboard, for example, it refers to a drive device that physically moves the writing screen.

[0013] The control means 40 is a means for comprehensively controlling the operation of the electronic blackboard device 100. For example, the control means 40 determines the writing position on the writing screen 10 and instructs the writing screen moving means 30 to move the writing screen. Control such as to do.

[0014] Next, specific examples of the embodiment of the present invention will be described in further detail.

[0015] (Example 1)

First, as an example in the embodiment of the present invention, Example 1 when the electronic blackboard device is realized by a display device with a touch panel will be described in detail.

FIG. 2 is a diagram showing an internal configuration of the electronic blackboard device in Example 1 of the embodiment of the present invention. The electronic blackboard device 200 mainly includes a display device 50, a touch panel 60, and a personal computer 70.

The display device 50 is a display device such as a plasma display or a liquid crystal display, and includes a display control unit 51 that controls screen display, and a display unit 52 that serves as a display screen.

The touch panel 60 is attached to the display screen of the display device 50 to detect input with a finger or a pen, and reflects the input result on the display unit 52 of the display device 50. A touch panel control unit 61 that transmits input information to a personal computer 70, which will be described later, and a sensor unit 62 that detects the position of a finger or pen. The sensor unit 62 is formed of a position sensor and a contact sensor as described above, and realizes a function as “writing position sensing means” for detecting a position on the display screen, that is, an input position. Further, the display unit 52 of the display device 50 and the sensor unit 62 of the touch panel 60 are combined to realize a function as a “writing screen”.

[0018] Next, the personal computer 70 includes a CPU 71, a touch panel driver 72, application software 73, control software 74, and the like. The personal computer 70 cooperates with the display control unit 51 of the display device and the touch panel control unit 61 to form an electronic blackboard. Realizes the function as a “control means” of the equipment The operation control of the display device 50 touch panel 60 is realized by executing control software 74 installed in advance by the CPU. In addition, the control software The operation of the key 74 is controlled by application software 73 having a user interface. The operation of the touch panel 60 is controlled by the touch panel driver 72.

Next, the operation of the electronic blackboard apparatus having the above configuration will be described. FIG. 3 is a flowchart illustrating the moving operation procedure of the writing screen of the electronic blackboard device in the first embodiment.

[0020] First, the operator of the electronic blackboard apparatus inputs the optimum writing position (step S101). This is an operation for registering in advance the input on the electronic blackboard, that is, which part of the writable area is easy for the operator to input. Even in the same electronic blackboard device, for example, the position where it is easy to write depends on the height of the operator, such as the lower area for small persons (children, etc.) and the upper area for large persons (adults, etc.). . In addition, when used for presentation of materials at the time of presentation, the position where writing is easy depends on the standing position, such as whether the presentation is made on the left or right side of the display device.

FIG. 4 is a schematic diagram for explaining the outline of the input of the optimum write position. For example, the operator 300 stands in front of the display of the electronic blackboard device 200 at the position shown in the figure, and designates the optimum writing position 80 with a finger or a pen. The sensor part 62 of the touch panel 60 detects the input, and the coordinate value data of the optimum writing position is transmitted to the personal computer 70 via the touch panel control unit 61. The CPU 71 that has obtained the coordinate value of the optimum writing position via the touch panel driver 72 and the control software 74 of the personal computer 70 sets the optimum writing range 81 related to the operator 300 from the coordinate value (step S102). The optimum writing range is set under a predetermined condition with reference to the coordinates of the inputted optimum position. For example, in FIG. 4, a rectangle of a predetermined size is set with the position coordinate as the top left vertex. Note that the optimum writing range does not necessarily have to be a rectangle, and any shape / size can be used. Further, the size and shape of the range may be set freely by the operator. Furthermore, the optimum writing position 80 and the optimum writing range 81 do not need to be displayed on the screen.

[0022] Next, the operator 300 starts writing (step S103). This is an operation to draw characters and figures by driving a pen or finger on the touch panel. The input contents from the touch panel 60 are grasped, and the locus drawn by the operator is displayed on the display unit 52 of the display device 50. . The display operation corresponding to the trajectory is performed using a known method, and therefore detailed description is omitted. To do. This display operation procedure is programmed as a part of the control software 74, and the locus is displayed by executing the program by the CPU 71.

[0023] When the operator performs writing, the sensor unit 62 detects writing at any time and transmits the coordinate value data of the writing position to the personal computer 70 via the touch panel control unit 61 (step S104). ). The CPU 71 of the personal computer 70 determines whether or not the acquired writing position is out of the optimum writing range force (step S105) .If the writing position is out of the optimum writing range, the writing operation is interrupted next. It is determined whether or not it is correct (step S106). In this embodiment, the interruption of writing is determined based on whether or not a force of 1 second or more has passed since the input was interrupted, but the determination time may be arbitrarily determined.

FIG. 5 is a schematic diagram for explaining a situation where the writing position is outside the optimum writing range. When the writing position gradually moves downward and falls outside the optimum writing range, the personal computer 70 determines that “the current writing position makes it difficult for the operator to perform writing 300 0 is in an unnatural posture”. . Then, the personal computer 70 instructs the display control unit 51 of the display device 50 to move the previous writing position to the optimum writing position that was initially set, that is, to move the writing screen (step S107).

) o

FIG. 6 is a schematic diagram for explaining a situation in which the writing screen including the locus and background in which writing has been performed has moved. As shown in the figure, the display on the writing screen is moved upward as a whole by the movement amount indicated by the movement vector 82. In other words, the entire writing screen including the background was moved so that the character position of “s”, which was the previous writing position, moved to the optimum writing position 80 set first.

Note that the optimum writing position 80 and the optimum writing range 81 are absolute coordinate values, and thus do not move even if the above movement is performed. Further, as described above, since the optimum writing position 80 and the optimum writing range 81 are not normally displayed, the operator 300 recognizes only that the writing track and the background are appropriately moved upward. By the movement operation of the writing screen as described above, the operator can continue writing at a position where writing is always easy, that is, in the normal U position, according to their height. Next, personal computer 70 determines whether or not to shift to the display mode (step S108). The display mode is a mode in which the area where writing has already been performed is moved to the upper center of the screen where it is most visible. FIG. 7 is a schematic diagram for explaining the outline of the display mode. When the operator 300 selects the display mode by a predetermined operation, as shown in the figure, the rectangular area 83 including all writing is moved upward in the center of the screen to enter the display mode (step S109). Through the above movement operation of the writing screen, the operator can improve the visibility of the contents written by himself / herself, which is particularly effective at the time of presentation or explanation of classes. During presentations, etc., there may be situations where the user wants to explain the position of the display, so buttons on the touch panel or the input section (not shown) of the personal computer have a scroll function for up / down / left / right. It is preferable to place it.

[0028] Thereafter, the personal computer 70 determines whether or not to return to the writing mode.

(Step S110), if returning, return to Step S103 and repeat the above procedure. On the other hand, if the write position is out of the optimum write range in step S105, or if the write operation is being performed in step S106, or the display mode is not shifted in step S108. Return to step s103, and repeat the above procedure.

[0029] (Example 2)

Next, FIG. 8 is a diagram showing an internal configuration of the electronic blackboard device in Example 2 of the embodiment of the present invention. Compared with the electronic blackboard device 200 of the first embodiment, the electronic blackboard device 201 of the second embodiment includes an operator identification device 90 for uniquely identifying an operator and an operator identification in the personal computer 70. The difference is that an identification information receiving unit 91 that receives identification information from the device 90 by wire or wirelessly is added.

[0030] The operator identification device 90 includes elements that can individually store and transmit operator identification information such as an optimum writing position unique to the operator, such as an input pen dedicated to a touch panel and a wireless IC tag. Further, the identification information receiving unit 91 receives the identification information transmitted from the operator identification device 90, and acquires information such as the optimum write position unique to each operator.

Next, the operation of the electronic blackboard apparatus having the above configuration will be described. Figure 9 shows the results for Example 2. 6 is a flowchart showing a moving operation procedure of a writing screen of the electronic blackboard apparatus. Hereinafter, a case where a wireless IC tag is used as the operator identification device 90 will be described.

[0032] First, when the operator wearing the wireless IC tag approaches the electronic blackboard apparatus 201, the identification information receiving unit 91 of the personal computer 70 displays the optimum write position information unique to the operator stored in the wireless IC tag. Receive (step S201). The CPU 71 that has acquired the coordinate value of the optimum writing position sets the optimum writing range related to the operator from the coordinate value (step S202).

FIG. 10 is a schematic diagram for explaining the outline of automatic setting of the optimum write range.

For example, as shown in FIG. 10 (a), when an adult operator A stands in front of the display of the electronic blackboard device 201, the optimal writing position information of the operator A stored in the attached wireless IC tag 90a is personal. Sent to computer 70. Then, based on the acquired coordinate value 80a, the optimum writing range 8 la of the operator A is set. On the other hand, as shown in FIG. 10 (b), when the operator B of the child stands in front of the display of the electronic blackboard device 201, the optimum writing position information of the operator B stored in the attached wireless IC tag 90b is personal. Sent to computer 70. Then, based on the acquired coordinate value 80b, the optimum write range 8 lb for the operator B is set. In the figure, an example is shown in which a predetermined equal interval is used as the optimum writing range up and down with reference to the Y coordinate of the optimum writing position.

The subsequent procedure from step S203 to step S210 is the same as the procedure from step S103 to step S110 in the flow chart of FIG. As described above, since the operator identification device installed by the operator provides the optimum writing position information unique to the operator, the optimum writing range can be obtained even if the operator does not perform the input operation of the optimum writing position. Is automatically set.

[0035] (Example 3)

Next, FIG. 11 is a diagram showing an internal configuration of the electronic blackboard device in Example 3 of the embodiment of the present invention. Compared with the electronic blackboard device 200 of the first embodiment, the electronic blackboard device 202 of the third embodiment includes a position sensor 92 for detecting the height and standing position of the operator, and the position sensor 92 in the personal computer 70. This is different from the location information receiving unit 93 that receives the location information. [0036] The position sensor 92 is composed of an infrared sensor or the like, and detects the height and standing position of the operator approaching the electronic blackboard device. Further, the position information receiving unit 93 receives the position information output from the position sensor 92 and uses it for setting the optimum writing position and optimum writing range unique to the operator.

Next, the operation of the electronic blackboard apparatus having the above configuration will be described. FIG. 12 is a flowchart showing a moving operation procedure of the writing screen of the electronic blackboard device in the third embodiment.

[0038] First, when the operator approaches the electronic blackboard device 202, the position sensor 92 installed in the vicinity of the electronic blackboard device detects the height and standing position of the operator, and the position information is the position information of the personal computer 70. The data is transmitted to the receiver 93 (step S301). The CPU 71, which has acquired the position information regarding the height and standing position of the operator, sets the optimum writing range for the operator as the coordinate value force (step S302). Note that the above-described procedure may be used as a method for setting the optimum writing range.

FIG. 13 is a schematic diagram for explaining the outline of automatic setting of the optimum writing range.

For example, as shown in FIG. 13 (a), when an adult operator C stands on the left side in front of the display of the electronic blackboard device 202, the position sensor 92 detects the height and standing position of the operator, and the position information is Sent to personal computer 70. Then, based on the coordinate value 80c of the optimum writing position where the height is also calculated, the optimum writing range 81c of the operator C is set to the left side of the display in an appropriate rectangle.

On the other hand, as shown in FIG. 13 (b), when the operator D of the child stands on the right side in front of the display of the electronic blackboard device 202, the position sensor 92 detects the height and standing position of the operator, and the position information is Sent to personal computer 70. Then, based on the coordinate value 80d of the optimum writing position where the height is also calculated, the optimum writing range 8 Id of the operator D is set to the right side of the display in an appropriate rectangle.

[0040] For example, when the optimum writing range is set on the upper side of the writing screen, since the operator is a tall operator, the range is enlarged, and when the optimum writing range is set on the lower side of the writing screen. It is possible to set the range to be different depending on the conditions, such as reducing the range because it is a short operator.

[0041] The subsequent steps from Step S303 to Step S310 are the same as the flowchart of FIG. Since the procedure from step S103 to step S110 in Yat is the same, the description is omitted. As described above, since the information on the height and standing position of the operator is provided also with the position sensor force, the optimum writing range is automatically set even if the operator does not perform the input operation of the optimum writing position.

[Example 4]

Next, the movement operation of the writing screen when the writing input target such as a button or answer column is already displayed on the writing screen will be described. Note that the internal configuration of the electronic blackboard apparatus according to the fourth embodiment of the present invention may be any of the electronic blackboard apparatuses according to the second embodiment or the third embodiment described above. Therefore, illustration and description of the internal configuration of the electronic blackboard device are omitted.

Next, the operation of the electronic blackboard apparatus having the above configuration will be described. FIG. 14 is a flowchart showing a moving operation procedure of the writing screen of the electronic blackboard device in the fourth embodiment.

[0044] First, there is a display on the display unit 52 of the display device 50 using spreadsheet software, text editor, presentation software, etc. that is activated as the application software 73, and an input target that accepts input from the touch panel 60 therein. The personal computer 70 determines whether there is a display area (step S401). If there is a display, then the personal computer 70 indicates that the operator is present at a position where writing can be performed on the electronic blackboard device based on detection by the operator identification device 90 or the position sensor 92. It is determined whether or not power is available (step S402).

[0045] If the operator is in the vicinity of the electronic blackboard device, the optimum writing position obtained by the procedure described in the second embodiment or the third embodiment is grasped (step S403), and the input target is the optimum writing position of the operator. It is instructed to move the writing screen, that is, to change the display so as to come to (step S404).

FIG. 15 and FIG. 16 are schematic diagrams for explaining a situation where a writing input target such as a button or answer column moves to an optimal writing position for the operator. For example, as shown in Fig. 15 (a), when an adult operator stands on the right side in front of the display of the electronic blackboard device, the operator identification device 90 or the position sensor 92 detects the operator and displays a button. The writing screen is moved so that moves to the optimal writing position of the operator (see 015 (b)). This These buttons are input target buttons that operate when the operator touches the display part of the touch panel.

Further, such an input target button may always come to the optimum writing position of the operator, or may move with the background after the first automatic setting. In particular, if the button to be input is a button for adjusting the screen position, it will be difficult to operate if the button itself is moved, so it is always fixed at the optimal position regardless of the movement of the background. desirable.

[0047] Further, as shown in FIG. 16 (a), when the operator of the child stands on the right side in front of the display of the electronic blackboard device, the operator identification device 90 or the position sensor 92 detects the operator and answers. The writing screen is moved so that the column display moves to the optimal writing position for the operator (see Fig. 16 (b)). This answer column is an answer column of an input target in which an answer can be input from the operator power touch panel.

[0048] In each of the above embodiments, the input request for the optimum write position and the display mode

When performing alignment, it is preferable to use an on-screen display user interface so that the operator can input easily.

As described above, the electronic blackboard device according to the embodiment of the present invention has the writing screen 10 for inputting characters and figures, and the writing position detection for detecting the input position with respect to the writing screen 10. Means 20, writing screen moving means 30 that moves the input position by moving the writing screen 10, and a reference position where the operator can easily input are set in advance. Is within the predetermined length, or whether the input position to the writing screen 10 is within the area set based on the reference position, and exceeds the predetermined length. In this case, the control unit 40 causes the writing screen moving unit 30 to move the writing screen 10 so that the most recent input position matches the reference position when it is out of the area. In addition, the writing position adjustment method of the electronic blackboard device according to the embodiment of the present invention includes a writing screen 10 for inputting characters and figures, and a writing position detecting step for detecting the input position with respect to the writing screen; The writing screen moving step to move the input position by moving the writing screen 10, and the operator can input and easily A quasi-position is set in advance, and whether or not the distance between the input position relative to the writing screen 10 and the reference position is within a predetermined length, or the input position relative to the writing screen 10 is set based on the reference position. Judgment is made on whether or not there is an area within the area, and if the specified length is exceeded or the area is out of the area, the most recent input position matches the reference position.

The writing screen moving step includes a control step for moving the writing screen 10.

In addition, the writing position adjustment program of the electronic blackboard device according to the embodiment of the present invention is

Has a writing screen 10 for inputting characters and figures, a writing position detecting step for detecting the input position with respect to the writing screen 10, and a writing screen movement for moving the input position by moving the writing screen 10. Step and a reference position that is easy for the operator to input are set in advance, whether or not the distance between the input position to the writing screen 10 and the reference position is within a predetermined length, or input to the writing screen 10 It is determined whether the position is within the area set based on the reference position, and if the specified length is exceeded or outside the area, the most recent input position matches the reference position. In this manner, the control step of moving the writing screen 10 in the writing screen moving step is executed by the computer.

As a result, the writing screen automatically moves so that writing can always be performed at the optimum writing position.

This eliminates the need for the operator to reach a high position, take a posture that makes writing difficult, such as greatly bending his back to write to a low position, or to move left and right.

In addition, even in the case of a small operator such as a child or a wheelchair operator, it is possible to achieve both writing ease and visibility.
