Abstract

This document discusses, among other things, apparatus and methods for controlling a haptic transducer. In an example, a haptic controller can include an active termination driver having a configurable output impedance. The active termination driver can be configured to drive a haptic transducer and to process back electro-magnetic force (EMF) of the haptic transducer to provide motion feedback of the haptic transducer. In an example, the haptic controller can include a processor to provide a command signal to the active termination driver and to determine a resonant frequency of the haptic device using the motion feedback of the haptic transducer.
