Abstract
An actuated stylus conditionally occludes or exposes a reflector. The actuation mechanism may be mechanical, electrical, or a combination. When the reflector is occluded and the stylus is in the field of view of an interactive projection, no light is reflected back to the projection system. When the reflector is exposed, light is reflected back to the projection system. The reflector may be exposed in a time coded sequence to encode information such as a stylus ID and user action.
