A touch panel (111) includes: a touchpad unit (111a) that repeatedly detects a touch position touched by operation body; a speed calculation unit that calculates movement speed of the operation body; a vibrator (111f); and a region setting unit (111c), when the speed at first time is less than threshold, sets first reaction region to be anterior in movement direction of the operation body, and when the speed is equal to or greater than the threshold, sets second reaction region that is smaller than the first reaction region to be anterior in the direction; and a vibration control unit (111e) that judges whether the operation body is inside the reaction region at second time after the reaction region setting, when the operation body is inside the reaction region, controls the vibrator to vibrate, and when the operation body is not inside the reaction region, controls the vibrator not to vibrate. |

1. An input device that vibrates to inform a user of that an operation body touches a region on a screen, the region being for receiving an operation instruction allocated to the region, the input device comprising:
a touch position detection module configured to repeatedly detect a touch position on the screen touched by the operation body while the operation body is in touch with the screen; a speed calculation module configured to calculate a movement speed at each detected touch position, the movement speed indicating a speed at which the operation body moves on the screen while being in touch with the screen; a vibrator; a region setting module configured to compare the movement speed at a touch position detected at a first time point with a threshold value, (i) when the movement speed is less than the threshold value, set a first reaction region on the screen so as to be positioned anterior to the detected touch position in a movement direction of the operation body, and (ii) when the movement speed is equal to or greater than the threshold value, set a second reaction region on the screen so as to be positioned anterior to the detected touch position in the movement direction, the second reaction region being smaller than the first reaction region; and a vibration control module configured to judge whether the operation body is positioned inside the set reaction region, with use of a touch position detected at a second time point after the reaction region is set, when the operation body is positioned inside the set reaction region, control the vibrator to vibrate, and when the operation body is not positioned inside the set reaction region, control the vibrator not to vibrate. |
