  When a fast-forward or rewind instruction is given to the medium playback application using the touch panel, it is generally considered that the user selects any button with the fast-forward button or the rewind button displayed. For example, the playback position can be continuously advanced by long-pressing the fast-forward button, and the playback position can be advanced by the minimum increase / decrease step by pressing it short once. Conversely, the playback position can be returned continuously by long-pressing the rewind button, and the playback position can be returned by the minimum increase / decrease step by pressing it once.

  By the way, when fast-forwarding or rewinding is performed by pressing and holding the fast-forward button or the rewind button, it is difficult to accurately adjust the reproduction position to the desired position. For this reason, it is necessary to set the approximate playback position by long-pressing these buttons, and then press the fast-forward button and rewind button several times to make fine adjustments to the final playback position. There is a problem that a complicated operation is required to stop the operation. This operation method is the same when searching for a desired broadcast station by manually changing the reception frequency in one direction in the radio receiver, and complicated operation is required to accurately match the reception frequency. Become. In addition, these problems are not limited to the case where the operation is performed using the touch panel, but the same applies to a case where a mechanical push button is pressed to perform fast forward or rewind.

  The present invention has been created in view of these points, and its purpose is to stop forward and backward feed (fast forward / rewind of the playback position and increase / decrease of the reception frequency) at an accurate position with a simple operation. It is to provide an information device, an operation method thereof, and an operation program.

In order to solve the above-described problem, an information device according to the present invention is an information device in which forward or backward information is performed according to a user's operation instruction, and a predetermined instruction for instructing forward or backward information.

The user can fast-forward or rewind the playback position by the minimum number of steps by pressing the fast-forward key B3 or the rewind key B4 once. The touch panel 22 can detect the pressed state of the fast-forward key B3 and the rewind key B4.

  The information feed processing unit 53 corresponds to the operation keys for instructing forward feed or reverse feed (manual up key A2 or manual down key A3 shown in FIG. 2, fast forward key B3 or rewind key B4 shown in FIG. 3). However, in the following description, these operation keys will be referred to as “specific operation keys” as necessary) while the pressed state is maintained (while the key is held down). Perform forward or reverse feed.

  For example, when the user continues to press (hold down) the manual up key A2 or the manual down key A3 in the state where the operation screen shown in FIG. 2 is displayed, the information feed processing unit 53 causes the radio tuner unit 16 to The FM broadcast reception frequency is continuously shifted to a higher side or a lower side at a constant speed (or so that the speed increases in proportion to the pressing time).

  When the user continues to press (hold down) the fast-forward key B3 or the rewind key B4 while the operation screen shown in FIG. 3 is displayed, the information-forward processing unit 53 causes the AV processing unit 18 to perform fast-forwarding. And rewinding at a continuous and constant speed (or so that the speed increases in proportion to the pressing time).

  The pressed position movement determination unit 54 detects that an arbitrary position on the touch panel 22 has been pressed by the user and that the pressed position has moved while maintaining the state where the specific operation key is pressed.

  The information feed changing unit 55 changes the method of forward or backward feeding of information by the information feed processing unit 53 according to the movement state of the pressed position detected by the pressed position movement determining unit 54. Specifically, the information feed changing unit 55 sets the forward feed amount or reverse feed amount of information by the information feed processing unit 53 in proportion to the amount of movement of the pressed position. More specifically, the information feed changing unit 55 temporarily stops the forward or reverse feed of information by the information feed processing unit 53 when the pressed position movement determining unit 54 detects the pressed position, and then moves the pressed position. The information feed amount by the information feed processing unit 53 is set according to the amount.

  Further, the information feed changing unit 55 sets a forward feed amount of information when the pressed position moves rightward or upward with reference to the initial position, and the pressed position is set to the left or with reference to the initial position. Sets the amount of forward feed of information when moving downward.

  The above-described operation unit 20, touch panel 22, and display device 32 are the operation means, the information feed processing unit 53 is the information feed means, the pressed position movement determination unit 54 is the pressed position movement determination means, and the information feed change unit 55 is the information feed The display device 32 corresponds to the changing means and the display means.

  The in-vehicle device 1 according to the present embodiment has such a configuration, and next, a procedure for changing a method of forward or backward feeding of information will be described.

  FIG. 4 is a flowchart showing an operation procedure for forwardly or backwardly feeding the FM broadcast reception frequency by manual operation while the operation screen shown in FIG. 2 is displayed.

  The information feed processing unit 53 determines whether or not the specific operation key (manual up key A2 or manual down key A3) has been pressed for a long time (step 100). If the specific operation key is not pressed for a long time, a negative determination is made and this determination is repeated. If the specific operation key is pressed long by the user, an affirmative determination is made in the determination of step 100.

  Next, the information feed processing unit 53 determines whether or not the long-pressed specific operation key is the manual up key A2 (step 102). If the manual up key A2 is pressed for a long time, an affirmative determination is made. In this case, the information sending processing unit 53 sends an instruction to the radio tuner processing unit 16 to continuously shift the reception frequency to the higher side (step 104).

  FIG. 5 is a diagram illustrating a specific example in which the manual up key A2 is pressed for a long time. In the example shown in FIG. 5, the user presses and holds down the manual up key A2 with the tip C1 of the index finger of the right hand, and this state is detected by the touch panel 22.

  If the manual down key A3 is pressed for a long time, a negative determination is made in the determination of step 102. In this case, the information sending processing unit 53 sends an instruction to the radio tuner processing unit 16 to continuously shift the reception frequency to the lower side (step 106).

  In parallel with the operation of continuously changing the reception frequency in step 104 or 106, the pressed position movement determination unit 54 determines whether an arbitrary position on the touch panel 22 is pressed by the user (step 108). When the arbitrary position is not pressed (when the pressing of the arbitrary position is not detected by the touch panel 22), a negative determination is made, and the process returns to step 100 to repeat the long press determination of the specific operation key.

  If an arbitrary position is pressed, an affirmative determination is made in step 108. Next, the information feed changing unit 55 sends an instruction to the information feed processing unit 53 to stop the operation of changing the reception frequency (step 110).

  FIG. 6 is a diagram illustrating a specific example in which another position is pressed while the manual up key A2 is kept pressed. In the example shown in FIG. 6, the user presses the manual up key A2 with the right index finger for a long time and presses another arbitrary position with the tip C2 of the thumb, and this state is detected by the touch panel 22.

  Next, the pressed position movement determination unit 54 determines whether or not the pressed position has moved (step 112). If it has not moved, a negative determination is made, and the process returns to step 108 to repeat the determination of pressing an arbitrary position. If the pressed position has moved, an affirmative determination is made in step 112.

  Next, the pressed position movement determination unit 54 calculates the amount of movement of the pressed position (step 114). Further, the information feed changing unit 55 determines whether or not the moving direction of the pressed position is the right side or the upper side (step 116). An affirmative determination is made when the direction of movement is right or up. In this case, the information feed changing unit 55 determines a feed amount (a change amount for changing the reception frequency) based on the calculated movement amount of the pressed position, and this feed amount is set to the reception frequency when the frequency transition is stopped. Is added to change the reception frequency to the higher side (step 118). On the contrary, when the moving direction is the left side or the lower side, a negative determination is made in the determination of step 116. In this case, the information feed changing unit 55 determines the feed amount based on the calculated movement amount of the pressed position, and lowers the reception frequency by subtracting this feed amount from the reception frequency at the time when the frequency transition is stopped. (Step 120). These changes in the reception frequency are performed while looking at the value of the reception frequency displayed in the reception frequency display area A1 (FIG. 2). Thereafter, the process returns to step 112 and the determination of the movement of the pressed position is repeated.

  FIG. 7 is a diagram illustrating a specific example of changing the reception frequency by moving the pressed position. As shown in FIG. 7, by moving the pressed position C2 in the right direction d1 or the upward direction d2, it is possible to change the reception frequency to the higher side with the feed amount corresponding to the movement amount. On the contrary, by moving the pressed position C2 in the left direction d3 or the downward direction d4, the reception frequency can be changed to the lower side with the feed amount corresponding to the movement amount.

  The pressing position C2 does not need to be moved accurately along any one of the right direction d1, the upper direction d2, the left direction d3, and the lower direction d4. For example, if the reception frequency is increased when the pressing position C2 is moved approximately in the right direction d1, and the reception frequency is decreased when the pressing position C2 is approximately moved in the left direction d2, If the reception frequency is increased when the movement direction of the position C2 is included in the first quadrant and the second quadrant, and the reception frequency is decreased when the movement direction of the pressed position C2 is included in the third quadrant and the fourth quadrant Good. Further, if the reception frequency is increased when the pressing position C2 is moved generally in the upward direction d2, and the reception frequency is decreased when the pressing position C2 is approximately moved in the downward direction d4, the pressing frequency is If the reception frequency is increased when the movement direction of the position C2 is included in the second quadrant and the third quadrant, and the reception frequency is decreased when the movement direction of the pressed position C2 is included in the fourth quadrant and the first quadrant Good.

  As described above, in the in-vehicle device 1 of the present embodiment, when performing forward or backward information transfer according to a user's operation instruction, the user presses an arbitrary position on the touch panel 22 and sets the pressed position. By a simple operation of moving, you can change the method of information forward and backward (specifically, set the feed amount), and stop information forward and backward at an accurate position. It becomes.

  Further, when a position other than the specific operation key is pressed, the forward or reverse feed of information is temporarily stopped, and the subsequent feed amount is set, so that the stop at the accurate position is further facilitated. In addition, by changing the direction in which the pressed position is moved, it is possible to arbitrarily adjust the amount of forward or backward feeding of information. It becomes possible to make adjustments while visually checking the amount of information to be fed, and it is possible to more easily stop forward feed and approximate feed at an accurate position.

  In addition, since the above-described detection of the specific operation key is performed using the touch panel 22, it is not necessary to provide a special key by hardware, and an inexpensive configuration can be obtained by using multi-touch detection of the touch panel 22. .

  Moreover, it is desirable that the information device of the present invention is mounted on a vehicle. By applying the present invention to the in-vehicle device 1 as an information device mounted on a vehicle, it is possible to stop forward and backward information at an accurate position with a simple operation, and a narrow and restrained posture. The operability can be improved.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation implementation is possible within the range of the summary of this invention. For example, in the above-described embodiment, the case where the reception frequency of the FM broadcast to be received is forward (changed to the higher side) or reverse (changed to the lower side) has been described using the operation screen shown in FIG. However, the present invention may be applied to the case where the playback position when playing back audio data or the like is forward-forwarded (fast forward) or reverse-forwarded (rewinded) using the operation screen shown in FIG. Alternatively, the present invention may be applied to information forward or backward using other operation screens.

  In the above-described embodiment, the manual up key A2 and the manual down key A3 (FIG. 2) as the specific operation keys, the fast forward key B3, and the rewind key B4 (FIG. 3) are displayed on the display device 32. Although the presence or absence of pressing is detected by the touch panel 22, these specific operation keys may be assigned to hardware keys included in the operation unit 20.

  In the above-described embodiment, the present invention is applied to the in-vehicle device 1, but the present invention may be applied to other information devices using a touch panel such as a portable terminal device, a desktop or a notebook personal computer.

  As described above, according to the present invention, when performing forward or backward information transfer according to a user's operation instruction, the user presses an arbitrary position on the touch panel and moves the pressed position. By a simple operation, it is possible to change the method for forward and backward feeding of information (specifically, to set the feed amount), and to stop the forward and backward feeding of information at an accurate position.
