Abstract
An active stylus includes a haptic feedback subsystem, an accelerometer, and a controller that controls the haptic feedback subsystem to generate a haptic pulse having predefined haptic characteristics. The controller receives a detected acceleration profile from the accelerometer. The detected acceleration profile is caused at least partially by propagation of the haptic pulse through a stylus body of the active stylus, and caused at least partially by attenuation of the haptic pulse by an external object contacting the stylus body. A current usage state of the active stylus is identified based at least in part on a comparison between the detected acceleration profile and a acceleration context model.
