Sculpted Waveforms with no or reduced unforced response
Abstract
An electronic device may generate a canceling component that reduces or eliminates the unforced response for a base waveform applied to a component haptic output device of the electronic device. The electronic device may create a sculpted waveform that has no or reduced unforced response and may store the created sculpted waveform. The electronic device may apply the sculpted waveform to the component haptic output device. In one embodiment, a space of at least possible parameters may be defined. Canceling component corresponding to points in the space may be iteratively tested. A heat map may be generated based on the unforced response cancellation or elimination of the canceling components corresponding to the points. Based at least on the heat map, a canceling component may be selected. A sculpted waveform may then be generated by combining the base waveform with the canceling component.
