Abstract
A computing device comprises a microphone, a trackpad, and a haptic actuator coupled to the trackpad. A memory stores instructions executable by a processor to drive the haptic actuator with a driving signal to generate a first trackpad sonic output. The first trackpad sonic output is measured using a signal from the microphone of the computing device. A sonic variance is determined by comparing the first trackpad sonic output to a target trackpad sonic output. The sonic variance is used to adjust the driving signal for the haptic actuator to an adjusted driving signal. The haptic actuator is driven with the adjusted driving signal to cause a second trackpad sonic output from the trackpad different from the first trackpad sonic output.
