  Next, the external appearance of the touch panel operating device 10 will be described with reference to FIG. The touch panel operation device 10 illustrated in FIG. 2 is a device that can be carried by a user. The display unit 400 is integrally provided on one surface of a rectangular shape, and the touch panel operation unit 401 is provided on the display unit 400. Yes.

  The touch panel operation device 10 illustrated in FIG. 2 includes an operation unit 104 on one or a plurality of surfaces of a rectangular housing. In FIG. 2, the operation unit 104 is illustrated on the same surface as the display unit 400, but may be provided on another surface. Further, the operation unit 104 may be a remote control device (not shown), or may be a device including only the touch panel operation unit 401 without including the operation unit 104 on each surface of the touch panel operation device 10. Furthermore, the acceleration sensor 301 may function as the operation unit 104 so that a predetermined operation is performed based on the acceleration received by the touch panel operation device 10.

  As illustrated in FIG. 2, the y-axis direction and the x-axis direction are defined on the same surface as the display unit 400 in the touch panel operating device 10, and the z-axis direction is defined with respect to the depth direction of the display unit 400. The acceleration sensor 301 detects acceleration applied in each direction of the touch panel operating device 10, and the rotation detection unit 310 extracts the acceleration in the x-axis direction and the y-axis direction from the accelerations in the respective directions detected by the acceleration sensor 301. By doing so, it is possible to detect the rotation of the touch panel operating device 10 in the xy plane which is the same surface as the display unit 400.

  Next, an operation example of the touch panel operating device 10 according to the first embodiment of the present invention will be described with reference to FIGS. 3 and 4. FIG. 3 is a flowchart showing an operation example of the touch panel operating device 10 according to the first embodiment of the present invention, and FIG. 4 shows a screen display example of the touch panel operating device 10 according to the first embodiment of the present invention. It is a conceptual diagram.

  In FIG. 3, as the rotation detection step, first, the rotation detection unit 310 determines whether or not the rotation of the display unit 400 is detected (step S100). In the case where the display unit 400 is an apparatus integrated with the touch panel operation device 10 as shown in FIG. 2, the determination in step S <b> 100 has the same meaning as the determination of the rotation detection of the touch panel operation device 10. Hereinafter, in another embodiment in addition to the present embodiment, the rotation of the display unit 400 can be replaced with the rotation of the touch panel operation device 10 depending on the form of the touch panel operation device 10.

  The determination in step S100 may start the process using any one of the directions on the same plane as the display unit 400 as a reference angle. An example of the state of step S100 is shown in FIG. The state shown in FIG. 4A is a state in which, for example, the rectangular touch panel operating device 10 is used in the horizontally long direction, and display contents such as images and documents are displayed on the display unit 400 in the horizontally long direction. In this state, for example, it is assumed that the touch panel operating device 10 is rotated clockwise on the same surface of the display unit 400.

  In step S100, when it is determined that the rotation of the display unit 400 is not detected (step S100: No), the determination in step S100 is performed again. That is, the rotation detection unit 310 sequentially detects the rotation of the display unit 400. In step S100, when it is determined that the rotation of the display unit 400 is detected (step S100: Yes), the rotation detection unit 310 continuously detects the rotation of the display unit 400, thereby rotating the rotation angle of the display unit 400. It is determined whether or not the angle exceeds a threshold value (step S101).

  For example, when the display unit 400 rotates on the display surface when the display unit 400 rotates on the display surface, the threshold angle in step S101 is, for example, a rotation reference angle in the state of FIG. The rotation angle at which the unit 211 changes the display direction of the display content.

  As a specific example, as shown in FIG. 4A, the touch panel operating device 10 uses its display surface in a horizontally long direction, and a state in which gravitational acceleration is applied in a downward direction on the paper surface is set as a reference angle. From this state, when the touch panel operating device 10 is rotated to the right, for example, the angle rotated 45 degrees in the right rotation direction becomes the threshold value. For this reason, when the image is rotated rightward beyond the threshold angle, the display orientation change control unit 210 rotates the display content 90 degrees counterclockwise as shown in FIG. Display suitable for use in The same applies to the left rotation of the touch panel operating device 10, and the angle rotated 45 degrees to the left is the threshold value.

  In step S101, when it is determined that the rotation angle of the display unit 400 exceeds the threshold value (step S101: Yes), the display orientation change control unit 211 detects the display unit 400 detected in step S100 and step S101. The display direction of the display content is changed to a direction corresponding to the rotation angle (step S102). In the process of step S102, the display direction of the operation display unit 402 is similarly changed in accordance with the change of the display content direction, and the touch detection range 403 associated with the operation display unit 402 is also operated, although not shown here. The orientation is changed simultaneously with the display unit 402.

  In step S101, when it is determined that the rotation angle of the display unit 400 does not exceed the threshold value (step S101: No), the process proceeds to step S100 to sequentially detect the rotation of the display unit 400.

  In step S102, when the display orientation of the display content is changed, the display orientation is changed and the operation control unit 202 invalidates the touch operation on the touch panel operation unit 401 (step S103). The invalidation of the touch operation in step S103 means that the touch operation received in the touch detection range 403 in terms of software, although the touch detection range 403 corresponding to the operation display unit 402 is set in the touch panel operation unit 401. This is a process to invalidate.

  FIG. 4B shows a state where the touch operation between step S103 and step S106 is invalidated. In FIG. 4B, the display angle of the display content including the operation display unit 402 is changed because the rotation angle of the touch panel operation device 10 exceeds the threshold value of 45 degrees. Even if the user performs a touch operation on the operation display unit 402 in this state, the process by the operation is not performed.

  In step S103, at the same time that the touch operation is invalidated, the operation control unit 202 starts counting a timer that measures the invalid time of the touch operation (step S104).

  In step S104, when the timer count starts, the operation control unit 202 determines whether or not a predetermined time has elapsed in the timer (step S105). When it is determined in step S105 that the predetermined time has not elapsed (step S105: No), the process of step S105 is repeated. If it is determined in step S105 that the predetermined time has elapsed (step S105: Yes), the operation control unit 202 cancels the touch operation invalidation process executed in step S103 (step S106), and performs this process. finish.

  The time measured in step S <b> 105 is a case where the display orientation of the display content is changed with the rotation of the display unit 400 when the user starts an operation for performing a touch operation on the operation display unit 402. In addition, it is preferable that the time is equal to or longer than the time for which the user can respond to the touch operation on the operation display unit 402 whose display direction has been changed by the user's recognition of the change in the display direction of the display content. Specifically, about 1 to 2 seconds is appropriate.

  FIG. 4C shows a state where the invalidation of the touch operation is canceled in step S106. In FIG. 4C, since the rotation angle of the touch panel operating device 10 exceeds the threshold value of 45 degrees, the display direction of the display content including the operation display unit 402 has been changed. When the operation display unit 402 is touched, processing corresponding to the touch operation is executed. FIG. 4C shows a state where the “Music” icon is touch-operated as an example of the operation display unit 402.

  By such processing, the display position of the icon or the like at the touch position where the user intended the touch operation is changed to the display direction by changing the display direction of the display content accompanying the rotation of the direction of the touch panel operation device 10 or the display unit 400. It is possible to prevent an erroneous operation due to a touch at a position unintended by the user due to a change caused by the change. Specifically, the touch operation is invalidated for a predetermined time from when the orientation of the touch panel operation device 10 or the display unit 400 exceeds a threshold value for changing the rotation direction of the display content. Can be prevented.

  It is also conceivable that the rotation angle of the display unit 400 changes before the predetermined time elapses in step S105. The processing from step S100 to step S101 is sequentially performed. For example, in a state where step S105 is No, the display unit 400 has not exceeded the threshold value determined to have exceeded in step S101 due to the reverse rotation detected in step S100. When the angle is reached, the processing from step S102 to step S106 may be executed from that point.

Even when the display unit 400 further rotates in the same direction from the threshold value determined to be exceeded in step S101 in the state where step S105 is No, even when the angle exceeds the next threshold value, Further, the processing from step S102 to step S106 may be executed.

  Next, an operation example of the touch panel operating device 10 according to the second embodiment of the present invention will be described with reference to FIGS. FIG. 5 is a flowchart showing an operation example of the touch panel operation device 10 according to the second embodiment of the present invention, and FIG. 6 shows a screen display example of the touch panel operation device 10 according to the second embodiment of the present invention. It is a conceptual diagram. In FIG. 5, the same processes as those in FIG. 3 describing the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  In step S102, when the display orientation of the display content is changed, the display orientation is changed and the operation control unit 202 erases the touch detection range 403 in the touch panel operation unit 401 (step S111). The erasing of the touch detection range 403 is a state in which the touch detection range 403 corresponding to the operation display unit 402 is not set and a touch operation by the user cannot be accepted.

  FIG. 6A shows the state up to the processing in step S102. In FIG. 6A, a touch detection range 403 is set for the operation display unit 402, and the user touches the position of the operation display unit 402, thereby the touch detection range 403 corresponding to the operation display unit 402. The touch operation is detected, and processing associated with the touch detection range in which the touch operation is detected is executed.

  FIG. 6B shows a state where the touch detection range 403 is erased in step S111. FIG. 6B shows a state in which the rotation angle of the touch panel operating device 10 exceeds the threshold value. In actuality, in the case of rightward rotation with respect to FIG. In a state of being rotated 45 degrees or more. In FIG. 6B, the display direction of the display content is changed by the process of step S102, and the touch detection range 403 is not set for the operation display unit 402 whose display direction is changed. Even if the user touches the display position of the operation display unit 402 in this state, the touch operation is not detected.

  When the touch detection range 403 is erased in step S111, the touch detection range 403 is erased, and at the same time, a timer that measures the passage of a predetermined time is activated (step S104). When it is determined that the time has elapsed (step S105: Yes), the operation control unit 202 sets the touch detection range 403 for the operation display unit 402 whose display orientation has been changed in step S102 (step S112), and this processing Exit.

  FIG. 6C shows a state where the touch detection range 403 is set in the operation display unit 402 whose display orientation has been changed in step S112. In FIG. 6C, the touch detection range 403 is set at the display position of the operation display unit 402, and the user touches the display position of the operation display unit 402 so that the touch operation is detected. The process associated with is executed. FIG. 6C shows a state where the “Music” icon is touch-operated as an example of the operation display unit 402.

  By such processing, the display position of the icon or the like at the touch position where the user intended the touch operation is changed to the display direction by changing the display direction of the display content accompanying the rotation of the direction of the touch panel operation device 10 or the display unit 400. It is possible to prevent an erroneous operation due to a touch at a position unintended by the user due to a change caused by the change. Specifically, the touch operation is performed by erasing the touch detection range 403 for a predetermined time from when the orientation of the touch panel operation device 10 or the display unit 400 exceeds a threshold for changing the rotation direction of the display content. Therefore, the above-described erroneous operation can be prevented.

  It is also conceivable that the rotation angle of the display unit 400 changes before the predetermined time elapses in step S105. The processing from step S100 to step S101 is sequentially performed. For example, in a state where step S105 is No, the display unit 400 has not exceeded the threshold value determined to have exceeded in step S101 due to the reverse rotation detected in step S100. When the angle is reached, the processing from step S102 to step S112 may be executed from that point.

Even when the display unit 400 further rotates in the same direction from the threshold value determined to be exceeded in step S101 in the state where step S105 is No, even when the angle exceeds the next threshold value, Further, the processing from step S102 to step S112 may be executed.

  Next, an operation example of the touch panel operating device 10 according to the third embodiment of the present invention will be described with reference to FIGS. FIG. 7 is a flowchart showing an operation example of the touch panel operating device 10 according to the third embodiment of the present invention, and FIG. 8 shows a screen display example of the touch panel operating device 10 according to the third embodiment of the present invention. It is a conceptual diagram. In FIG. 7, the same processes as those in FIG. 3 describing the first embodiment and FIG. 5 describing the second embodiment are denoted by the same reference numerals and the description thereof is omitted.

  In step S101, when it is determined that the rotation angle of the display unit 400 exceeds the threshold value (step S101: Yes), the display orientation change control unit 211 detects the rotation of the display unit 400 detected in step S100 and step S101. The display direction of the display content is changed to the direction corresponding to the angle (step S121). In the process of step S121, only the direction of the display content is changed, and the display direction of the touch detection range 403 corresponding to the operation display unit 402 in the display content is not changed.

  If the display orientation of the display content is changed in step S211, the operation control unit 202 starts counting a timer that measures the time until the touch detection range 403 is erased at the same time when the display orientation is changed. (Step S122).

  In step S122, when the timer count starts, the operation control unit 202 determines whether or not a predetermined time has elapsed in the timer (step S123). If it is determined in step S123 that the predetermined time has not elapsed (step S123: No), the process of step S123 is repeated. If it is determined in step S123 that the predetermined time has elapsed (step S123: Yes), the operation control unit 202 erases the touch detection range 403 in the touch panel operation unit 401 (step S111).

  FIG. 8B shows a state in which the display orientation of the display content is changed in step S121 and the display orientation of the touch detection range 403 is not erased until the predetermined time has elapsed in step S123. FIG. 8B shows a state in which the rotation angle of the touch panel operating device 10 exceeds the threshold value. In actuality, in the case of the clockwise rotation with respect to FIG. In a state of being rotated 45 degrees or more. In FIG. 8B, the display direction of the display content is changed by the process of step S121, and the display direction of the operation display unit 402 as the display content is changed, but corresponds to the operation display unit 402. The orientation of the touch detection range 403 is not changed.

  When the user performs a touch operation on the position of the touch detection range 403 in the state of FIG. 8B, not the operation display unit 402 in the state of FIG. 8B but the operation display unit in the state of FIG. Processing corresponding to 402 is executed. The reason for setting such a time is that when the user starts an operation for performing a touch operation on the desired operation display unit 402 in the state of FIG. When the display orientation of the display content is changed, the user cannot immediately respond to the change in the display orientation, and touches the operation display unit 402 in FIG. 8A despite the change in the display orientation. Resulting in.

At this time, by setting the touch detection range 403 at a position corresponding to the operation display unit 402 in FIG. 8A for a predetermined time, an operation intended by the user can be executed. The time measured in step S123 may be set to the time from when the user visually recognizes that the display orientation of the display content has been changed to when the touch operation on the operation display unit 402 after the change of the display orientation can be executed. More specifically, about 0.2 seconds is appropriate.

  After step S111, providing an erase time for the touch detection range 403 is the same as in the second embodiment. If the predetermined time counted in step S105 is the first predetermined time and the predetermined time counted in step S123 is the second predetermined time, the second predetermined time is shorter than the first predetermined time. Is preferred. Thereby, the user can perform a touch operation appropriately without an erroneous operation.

  By such processing, the display position of the icon or the like at the touch position where the user intended the touch operation is changed to the display direction by changing the display direction of the display content accompanying the rotation of the direction of the touch panel operation device 10 or the display unit 400. It is possible to prevent an erroneous operation due to a touch at a position unintended by the user due to a change caused by the change. Specifically, the display direction of the display content including the operation display unit 402 is determined for a predetermined time from when the orientation of the touch panel operation device 10 or the display unit 400 exceeds a threshold value for changing the rotation direction of the display content. The direction of the touch detection range corresponding to the operation display unit 403 is not changed. For this reason, the user can prevent the touch operation intended immediately before the change of the display direction from being executed due to the change of the display direction, and can prevent the above-described operations.

  The embodiment of the present invention can be variously modified without departing from the gist thereof. For example, as an example of the touch panel operation device 10 in each of the above embodiments, the display unit 400 is described as an example integrated with the touch panel operation device 10, but only the display unit 400 rotates as shown in FIG. It may be a simple device.

  The touch panel operating device 10 shown in FIG. 9 has a structure in which only the display unit 400 provided with the touch panel operating unit 401 can rotate with respect to the main body, and the rotation sensor 301 provided in the display unit 400 or The rotation of the display unit 400 is detected by a mechanical, electrical, optical sensor, or the like provided in a coupling unit between the display unit 400 and the main body. 9A is used in the landscape direction as an example of the reference angle of the display unit 400. When the user rotates the display unit 400, the display unit 400 rotates 90 degrees as illustrated in FIG. 9B. Can be used. Even with such a touch panel operating device 10, similar effects can be obtained by realizing the various embodiments described above.

  Further, a program to which the operation flow in each of the embodiments described above is applied may be installed and operated on a computer that operates the touch panel operating device 10. Specifically, a program that causes the control unit 200 to execute and operate the program is stored in a RAM (not shown) or the like in the control unit 200. The computer that executes the program may be a computer that externally controls the touch panel operating device 10 in addition to the control unit 200, and the program may be stored in the storage unit 103 or another device other than the RAM. Further, the program to be installed may be distributed via a telecommunication network or may be distributed via a recording medium.
