Abstract
A haptic output device includes an actuator to generate a haptic effect, and a signal transmitter to transmit a driving signal and a braking signal to the actuator. After stopping the driving signal, the signal transmitter transmits no signal for a blank time period, and thereafter transmits the braking signal. The braking signal has a frequency equal to that of the driving signal, and a phase of the braking signal is opposite to that of the driving signal.
