Audio enhanced simulation of high bandwidth haptic effects

Abstract:

A system generates haptic effects using at least one actuator and at least one speaker. The system receives a high definition ("HD") haptic effect signal and a corresponding audio signal if audio is to be played. The system generates a standard definition ("SD") haptic effect signal based at least on the HD haptic effect signal, and generates an audio based haptic effect signal based at least on the HD haptic effect signal. The system mixes the audio signal and the audio based haptic effect signal, and then substantially simultaneously plays the SD haptic effect signal on the actuator and plays the mixed signal on the speaker.
