Tactile sensation presentation apparatus, tactile sensation presentation method, drive signal generation apparatus, and drive signal generation method

摘要

A haptic feedback device includes: a plurality of actuators for vibrating a panel; a touch information obtaining unit for obtaining a plurality of touch positions on the panel; a haptic feedback determining unit for determining a first touch position at which to provide haptic feedback from among the plurality of touch positions; and a driving signal obtaining unit for obtaining first driving signals for driving the actuators to vibrate the panel at the first touch position according to a first haptic signal and vibrate the panel at a second touch position more weakly than at the first touch position, the first driving signals being generated using transfer functions from the actuators to the first touch position or a vicinity thereof and transfer functions from the actuators to the second touch position or a vicinity thereof.
