Energy savings mode for silent haptics

Abstract:

A method and system for energy savings with silent haptics is presented. A haptically-enabled device includes a processor that executes a haptic track containing haptic instructions. The haptic track is analyzed to determine the presence of a zero-force interval, also known as a silent haptic. The duration of the zero-force interval is determined, and if the duration exceeds a pre-determined threshold, then the system or method enters an energy savings mode. An overhead time associated with the terminating of the energy savings mode is determined. And, the energy savings mode is terminated at the conclusion of the zero-force interval less the overhead time.
