Abstract
A haptic output device having an actuator and a processor is presented. The actuator is configured to generate a haptic effect. The processor is configured: (i) to communicate a driving signal to the actuator, wherein the driving signal comprises at least one cycle of a periodic signal, and wherein the driving signal has a first frequency that is different than a resonant frequency of the actuator; (ii) to determine, based on the first frequency of the driving signal, a starting time of a braking signal, wherein a frequency of the braking signal is the resonant frequency of the actuator; (iii) to determine, based on the first frequency of the driving signal, an amplitude of the braking signal; and (iv) to communicate the braking signal to the actuator at the determined starting time and at the determined amplitude.
