Patent ID: 8493189

Claim:
A haptic feedback controller for controlling controlled equipment in response to a pointing operation performed by a user's finger along a predetermined pointing path, and for imparting haptic feedback corresponding to the pointing operation to the finger, the haptic feedback controller comprising: a pointing position detecting sensor which is arranged along the predetermined pointing path and is configured to detect a pointing position of the finger when the pointing operation is performed; a haptic feedback imparting device including an elastic body arranged along the predetermined pointing path and a piezoelectric element fixed to the elastic body for generating a vibration corresponding to a high frequency voltage when the high frequency voltage is applied to the piezoelectric element, and the haptic feedback imparting device configured to impart the haptic feedback to the finger through the vibration generated by the piezoelectric element by the intermediary of the elastic body; and a piezoelectric element control device which is configured to control the piezoelectric element based on feedback information outputted from the controlled equipment.
