Abstract
Computing devices and methods for adjusting a driving signal for a haptic trackpad are disclosed. In one example, a computing device comprises a trackpad that comprises a printed circuit board. An accelerometer is affixed to the printed circuit board and a haptic actuator is coupled to the trackpad. A memory stores instructions executable by a processor to drive the haptic actuator to cause a first trackpad acceleration. The accelerometer measures the first trackpad acceleration, and an acceleration variance is determined by comparing the first trackpad acceleration to a target acceleration. The acceleration variance is used to adjust a 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 acceleration different from the first trackpad acceleration.
