The method of driving the haptic feedback device and a haptic feedback device
2013
When providing a tactile feedback device, for operating the operation target image to make become three-dimensional model of the operation target of the rotation by the rotation of the operation target image to the situation will tactile prompt to enable a user to sense the feedback operation. The haptic feedback device includes a determination unit (105), distance sliding on the touch screen (101) as the sliding distance calculated; a display control unit (106), the sliding distance transformation as the operation target image (3) of the rotation angle of the the operation target image (3) after rotating the display unit (103); vibration control unit (107), when rotating the operation target image (3) starts to drive waveform a predetermined amplitude and frequency to drive the vibration unit (102 ), with the increase in sliding distance of the amplitude of the drive waveform is reduced, and the vibration control unit (102), so that the operation target image (3) to stop rotation of the drive after a predetermined period of time passes waveform amplitude is 0 , thereby reducing the resistance of the sense of rotation of the operating time of the target image (3) is feedback.
