Abstract

Described herein are embodiments for reducing haptic vibrations for electronic devices. Embodiments of an oscillation reduction scheme learned offline are disclosed for minimizing the acceleration for a haptic vibrator. A pattern and braking generation module outputs a pattern signal for amplification and then for driving the haptic vibrator. An accelerometer measures acceleration induced by vibration from the haptic vibrator. The pattern and braking generation module adjusts the pattern signal based on the measured acceleration to identify an optimal amplitude for a braking signal at each time frame. Such a closed-loop braking optimization process may be implemented to achieve an optimal or desired braking scheme for enhanced user haptic feedback.
