Abstract
Official abstract text for this publication.
A haptic output device includes an actuator that provides a haptic effect and a signal transmitter that transmits a driving signal and a braking signal to the actuator. The driving signal includes a first driving waveform in a first half cycle, a second driving waveform, following the first driving waveform, in a second half cycle, and a third driving waveform, following the second driving waveform, in a third half cycle. The braking signal includes a braking waveform following the third driving waveform. The polarities of the voltage values of the first driving waveform and second driving waveform are opposite to each other. The polarities of the voltage values of the second driving waveform and third driving waveform are opposite to each other. The braking waveform has a phase opposite to the phase of the driving signal. The third driving waveform has a higher frequency than the first driving waveform.
