Description

  The present invention relates to a method of remotely operating a terminal device having a configuration in which two terminals of a parent device and a child device can be combined and separated using a touch pad of the child device at the time of separation.

  When the display device is remotely operated with the touch pad on the remote control device, it is known that the aspect ratio of the touch pad on the remote control device and the display screen of the display device is the same. This can solve the problem that the aspect ratio of the touch pad and the aspect ratio of the display screen do not coincide with each other, so that a touch area where operation becomes invalid on the touch pad is generated (see Patent Document 1). .

  Further, it is known that a data processing apparatus equipped with a touch pad switches between a relative coordinate mode and an absolute coordinate mode. Thereby, the user can perform input operations such as character input and graphic drawing by a desired input method according to the work contents and individual differences (see Patent Document 2).

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
FIG. 1 is a schematic configuration diagram of a terminal system according to Embodiment 1 of the present invention. The terminal system includes a slave terminal 10 that is a first terminal and a master terminal 20 that is a second terminal. The handset terminal 10 which is the first terminal has a touch pad 11. The master terminal 20 as the second terminal is equipped with a display unit 21. As a specific example of the handset terminal 10, a mobile phone, a PDA, a smartphone, or the like that includes a touch pad is applicable. In addition, a touch panel can be used instead of the touch pad. Specific examples of the master terminal 20 may include a personal computer (PC), a notebook personal computer (PC), a television device, and the like.

  FIG. 2 is a hardware block configuration diagram of handset terminal 10 in the embodiment of the present invention. In FIG. 2, the handset device 10 includes a touch pad 11, a short-range wireless communication unit 12, a direction detection unit 13, and a control unit 14.

  The touch pad 11 is a pointing device that moves the mouse pointer displayed on the screen of the parent device terminal 20 by tracing the surface with a finger.

  The short-range wireless communication unit 12 transmits information on the direction detected by the direction detection unit 13 described later to the parent device terminal 20. Specifically, the short-range wireless communication unit 12 can transmit and receive information to and from the parent device terminal 20 by short-range wireless communication using, for example, Bluetooth, WLAN, IrDA, or the like.

  The direction detection unit 13 detects the direction of the slave terminal 10 that is the first terminal. Specifically, for example, a geomagnetic sensor can be used as the direction detection unit 13.

  The control unit 14 is a part that controls information to be transmitted to the base terminal 20 using the short-range wireless communication unit 12 based on the coordinate information acquired from the touch pad 11 and the direction information acquired from the direction detection unit 13.

  FIG. 3 is a hardware block configuration diagram of base unit terminal 20 according to Embodiment 1 of the present invention. The master terminal 20 includes a display unit 21, a short-range wireless communication unit 22, a direction detection unit 23, a control unit 24, an angle difference detection unit 25, and a coordinate correction unit 26.

  The display unit 21 displays information on the parent device terminal 20.

  The short-range wireless communication unit 22 is the short-range wireless communication using Bluetooth, WLAN, IrDA, etc., similar to the short-range wireless communication unit 12 of the child device terminal 10, and transmits / receives information to / from the child device terminal 10. It can be performed.

  The direction detection unit 23 detects the direction of the parent terminal 20 that is the second terminal. Specifically, for example, a geomagnetic sensor can be used for the direction detection unit 23.

  The angle difference detection unit 25 detects an angle difference from the direction information of the direction detection unit 13 and the direction information of the direction detection unit 23.

  The coordinate correction unit 26 corrects the coordinate information of the touch pad based on the direction information of the angle difference detection unit 25.

  The control unit 24 reflects the coordinate information corrected by the coordinate correction unit 26 on the display unit 21.

  FIG. 4 is a flowchart for explaining operation processing of the terminal system according to Embodiment 1 of the present invention.

  First, the touch pad 11 of the handset terminal 10 acquires coordinates (step S11). Next, the direction detection unit 13 of the handset terminal 10 detects the direction (step S12). Next, the detected coordinate information and direction information are transmitted from the child device terminal 10 to the parent device terminal 20 via the short-range wireless communication unit 12 (step S13). Next, the direction detection unit 23 of the parent device terminal 20 detects the direction of the parent device terminal 20 (step S14). Next, the angle difference detection unit 25 detects the angle difference from the direction information of the child device terminal 10 received in step S13 and the direction information of the parent device terminal 20 acquired in step S14 (step S15). Next, the coordinate correction unit 26 performs a threshold determination process on the angle difference detected in step S15. If the threshold determination condition is satisfied (YES in step S16), the coordinate correction unit 26 notifies the corrected coordinate axis to the control unit 24 that controls the screen, and the control unit 24 controls the screen ( Step S17). As a result, the screen control with the coordinate axis corrected is reflected on the display unit 21 (step S18). On the other hand, if the threshold determination condition is not satisfied in step S16 (NO in step S16), the coordinate correction unit 26 performs screen control in which the coordinate axis is not corrected on the display unit 21 without correcting the coordinate axis. (Step S18). In step S16, if the threshold determination condition is not satisfied, a hysteresis can be provided to prevent the coordinate axes from being frequently corrected near the threshold. For example, when the angle θ is set as a threshold value, correction is performed when the angle θ is rotated clockwise. However, the rotation angle is less than θ after rotating counterclockwise from the above state (the state rotated by the angle θ). However, if the difference from θ is less than or equal to α, correction is not performed. Here, α is set to a value that prevents the coordinate axis from being frequently corrected, and is a value smaller than θ.

  FIG. 5 is a specific example of coordinate axis correction of the terminal system according to Embodiment 1 of the present invention. This is a control method for detecting the orientation of the four sides of the housing of the handset terminal 10 and correcting so that the direction perpendicular to the side portion is always the Y axis of the coordinate axis of the touchpad. This coordinate axis correction technique makes it easy to understand the coordinates intuitively and improves operability.

In FIG. 5, the coordinate information and the direction information transmitted from the child device terminal 10 to the parent device terminal 20 are received by the parent device terminal 20. Then, θ is detected as an angle difference in the angle difference detection unit 25 based on the coordinate information and direction information received from the child device terminal 10 and the direction information detected by the parent device terminal 20. In the present invention, the correction process varies depending on the range of θ. Specifically, the following is performed (the case where the angle difference θ is positive is shown. The same applies when the angle difference θ is negative).
When 0 <θ <= π / 2, coordinate correction is not performed.
When π / 2 <θ <= π, the coordinate axis is π / 2, and correction is performed to rotate in the direction opposite to the rotated direction.
In the case of π <θ <= 3π / 2, the coordinate axis is π, and correction is performed to rotate in the direction opposite to the rotated direction.
In the case of 3π / 2 <θ <= 2π, correction is performed in which the coordinate axis is rotated in a direction opposite to the direction rotated by 3π / 2.
That is, the coordinate correction unit 26 corrects the coordinate information of the touch pad 11 so as to rotate in the direction opposite to the detected angle difference θ. This correction is a control for correcting the direction perpendicular to the side portion of the handset terminal 10 to always be the Y axis of the coordinate axis of the touchpad.

  By carrying out the above, it is possible to intuitively move the mouse cursor with the same feeling.

  As described above, according to the terminal system in the first embodiment of the present invention, care is taken about the orientation in which the slave terminal such as a portable information terminal with a touch pad and the master terminal such as an electronic device with a display are placed. In addition, the touchpad can be operated with a natural sense of direction.

  In the above description, the child device terminal 10 and the parent device terminal 20 have been described as being separated. However, the child device terminal 10 can be stored in the parent device terminal 20, and the child device terminal 10 and the parent device terminal 20 can be accommodated. When the terminal 20 is separated, the slave terminal 10 and the master terminal 20 can detect the direction and perform the above correction. In this case, the slave terminal 10 is accommodated in the master terminal 20 so as to include a sensor (for example, a proximity sensor, a contact sensor, etc.) (not shown) that detects whether or not the slave terminal 10 is accommodated. If this is detected, the correction process is not performed. Further, when the child device terminal 10 is stored in the parent device terminal 20, the child device terminal 10 and the parent device terminal 20 may not detect the direction and may not perform the above correction. In this way, usability can be further improved.

  ADVANTAGE OF THE INVENTION According to this invention, touch pad operation in a natural direction sense is attained, without worrying about the direction which sets | maintains child machine terminals, such as a portable information terminal with a touch pad, and parent machine terminals, such as an electronic device with a display. . Therefore, the present invention is useful as a terminal system including a first terminal having a touch pad and a second terminal having a display screen.
