Abstract

A system in which haptic effects are generated using an actuator receives a frequency response for the actuator at a standard voltage and generates a lookup table for an overdrive voltage based on the frequency response. The system then receives a haptic signal for the haptic effect and extracts one or more frequencies for the haptic signal. The system then determines the corresponding overdrive voltage from the lookup table for each of the frequencies and, for each of the frequencies, applies the corresponding overdrive voltage to the actuator. The overdrive voltage is greater than or equal to the standard voltage.
