Abstract
An example wearable device includes a haptic actuator to produce a haptic vibration in response to a target input waveform, a haptic effect sensor to measure a haptic vibration corresponding to the haptic vibration and to output a measured haptic vibration waveform and a feedback circuit to modify the target input waveform to reduce a difference between the haptic vibration and a measured haptic vibration waveform.
