Abstract:
A system, method, and computer program product for automatically providing a haptic stylus based interface for enhanced user interaction with touch screen devices are disclosed. The stylus communicates with the touch screen device to report stylus operating information from onboard sensors, and to receive application program instructions defining feedback and friction forces to be applied by onboard actuators. The applied feedback and friction forces may be independently controlled. Friction forces are provided via a rolling contact ball gripping mechanism that mimics varying physical engagement between the contact ball and a touch screen display surface by controlling the relative rotational freedom of the contact ball. Embodiments of the invention enable a haptic stylus to mimic three-dimensional interactions for gaming, object manipulation and sculpting, and non-contact proximity-based stylus operation scenarios.
