Are arranged.
- the control unit 15 determines whether or not the pressing load detected by the load detection unit 12 still satisfies a predetermined load standard (Ste S21).
- step S21 when it is determined that the pressing load no longer satisfies the predetermined load criterion, the control unit 15 changes the display mode of the object that has been pressed and displayed by accepting the input from the operator, and displays the pressing display. It returns to the original object before being displayed on the display unit 14 (step S27).

- the release tactile sensation with respect to the click tactile sensation can be presented by vibrating with the vibration pattern. Therefore, combined with the click tactile sensation during the operation accompanied by the pressing force, a release tactile sensation closer to the push button switch can be presented to the operator.
- step S21 if it is determined in step S21 that the pressing load still satisfies the predetermined load criterion, the control unit 15 moves the pressing position outside the key area based on the position information from the touch sensor 11. It is determined whether or not (step S22). That is, in this case, the control unit 15 causes the position of the contact detected by the touch sensor 11 to move from the key region to the outside of the key region while the pressing load detected by the load detection unit 12 satisfies a predetermined load standard. It is determined whether the user has left.
- the position corresponding to the object other than the key or the like from the position corresponding to the inside of the object such as the key or the like while the pressing load satisfying the predetermined load standard is applied to the touch panel 11. This corresponds to an operation of moving the position of a finger or the like that is operated by applying a pressing force on the touch panel 11.
- step S22 when the pressing position has not shifted to the outside of the key area, the control unit 15 returns to step S21 and determines whether or not the pressing load still satisfies a predetermined load standard. If it is determined in step S21 that the pressing load no longer satisfies the predetermined load standard, the operations of steps S27 and S28 are performed as described above.
- step S23 the control unit 15 determines whether or not the pressed position shifts into the key area of the key adjacent to the key area. That is, in step S23, the position of the contact detected by the touch sensor 11 is the key area of the object for which the current contact is detected while the pressing load detected by the load detection unit 12 satisfies the predetermined load standard. From this, it is determined whether or not the key area of the object adjacent to this has been transferred.
- step S23 when the pressed position does not move into the key area of the key adjacent to the key area, the control unit 15 performs the operations of step S27 and step S28.
- the case where the process proceeds from step S23 to step S27 is a case where the pressed position has moved out of the key area (Yes in step S22) but has not moved into the key area of the adjacent key (No in step S23). Yes, that is, when the pressed position moves to a position where the key object does not exist. Therefore, in this case, the control unit 15 restores the original display of the object that has been received and pressed (step S27), and drives the tactile sensation providing unit 13 with a predetermined drive signal to present the release tactile sensation. (Step S28).
- step S23 when the pressed position shifts to the key area of the key adjacent to the key area, the control unit 15 changes the display mode of the object that was originally received and pressed to display the pressed key area. The original object before being displayed is restored (step S24). Next, the control unit 15 changes the display mode of the object in the adjacent key area corresponding to the previous position to which the pressing position has shifted and displays the object on the display unit 14 (step S25).
- the control unit 15 drives the tactile sensation providing unit 13 with a predetermined drive signal to vibrate the touch sensor 11 with a predetermined vibration pattern set in advance, and clicks on step S15.
- a tactile sensation different from the tactile sensation and the release tactile sensation in step S28 is presented (step S26).
- the tactile sensation presented in step S26 is not a click tactile sensation that informs the operator that the pressed position has moved into the key area, or a release tactile sensation that has moved out of the key area.
- the tactile sensation indicates that the area has shifted from the area to the key area of another adjacent key.
- Such a tactile sensation is preferably a tactile sensation that is easily distinguishable from other tactile sensations for the operator, for example, a stimulus that repels the sense of touch.
- the tactile sensation presented in step S26 is not limited to this “flick” tactile sensation, and the tactile sensation different from the above-mentioned click tactile sensation and release tactile sensation by appropriately setting the strength and frequency of vibration. Any tactile sensation can be provided.
- the tactile sensation presented in step S26 may be a different tactile sensation depending on the form of the object before and after the transition when the pressed position transitions to the adjacent key area in step S23.
- it can be set so that a large tactile sensation is presented when the area of the transferred object is relatively large when the pressed position moves to an adjacent key area in step S23.
- different tactile sensations can be made.
- different tactile sensations can be set according to the shape of the object before and after the transition (appearance, that is, shape, pattern, color, etc.) rather than the size of the object before and after the slide operation transitions.
- the control unit 15 when the control unit 15 detects that the pressing position that satisfies the predetermined load standard has moved out of the predetermined area and has moved into another predetermined area, the first tactile sensation ( For example, the drive of the tactile sensation providing unit 13 is controlled so as to present a tactile sensation different from the second tactile sensation (for example, release tactile sensation).
