Method and apparatus for localization of haptic feedback

摘要

In an embodiment, a haptic feedback system includes a plurality of actuators to provide tactile feedback associated with an input surface. Each actuator is adapted to be activated independently of the other actuators. The system further includes a controller to activate a first actuator of the plurality of actuators to induce a first vibration at a selected input location of the input surface and to activate one or more additional actuators to induce at least a second vibration to localize the first vibration at the selected input location.

1. A controller in communication with an actuator of a haptic feedback system, the controller comprising:
a waveform generator in communication with the actuator and configured to:
apply an activation waveform to the actuator to produce a haptic output;generate a suppression waveform based at least in part on vibrations propagating along or through a surface to which the actuator is coupled; andapply the suppression waveform to the actuator to dampen the vibrations propagating along or through the surface.
