Abstract
A haptic output apparatus includes a vibration system having one or more resonance frequencies, the vibration system including an actuator configured to vibrate in accordance with an input signal, and including an object coupled to the actuator and configured to be excited in response to the vibration of the actuator. The haptic output apparatus includes a controller configured to control driving of the actuator. The controller corrects a drive signal using at least one correction model to output the corrected drive signal to the actuator as the input signal, the correction model being preliminarily generated based on the resonance frequencies. Alternatively, the controller outputs a control signal to the actuator as the input signal, the control signal being preliminarily generated using the correction model.
