Abstract
A haptic feedback controller of the present invention includes: a pointing position detecting sensor which is arranged along a fingertip pointing path and detects a pointing position of a fingertip when a pointing operation is performed along the fingertip pointing path; a haptic feedback imparting device which has a piezoelectric element arranged along the fingertip pointing path and generates vibrations depending on a high frequency voltage when the voltage is applied thereto and an elastic body which is fixed to the piezoelectric element, and imparts predetermined haptic feedback to the fingertip due to vibrations generated by the piezoelectric element; and a piezoelectric element control device which controls the piezoelectric element based on feedback information outputted from controlled equipment. According to the present invention, it is possible to provide a haptic feedback controller which is suitable for controlling controlled equipment in response to a pointing operation performed by a user with his/her fingertip and, at the same time, is suitable for equipment such as portable equipment deemed necessary to satisfy demand for reduction of thickness and miniaturization.
