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. |

1. A haptic output device, comprising:
an actuator configured to generate a haptic effect; and a processor configured
to communicate a driving signal to the actuator, wherein the driving signal comprises at least one cycle of a periodic signal, wherein the driving signal is communicated to the actuator during the at least one cycle, and wherein the driving signal has a first frequency that is different than a resonant frequency of the actuator,to determine, based on the first frequency of the driving signal, a starting time of a braking signal, wherein the braking signal has a reverse phase to a phase of the driving signal, and wherein a frequency of the braking signal is the resonant frequency of the actuator,to determine, based on the first frequency of the driving signal, an amplitude of the braking signal, andto communicate the braking signal to the actuator at the determined starting time and at the determined amplitude. |
