Existing approaches to 3D input on wall-sized displays include tracking users with markers, using stereo- or depth-cameras or have users carry devices like the Nintendo Wiimote. Markers makes ad hoc usage difficult, and in public settings devices may easily get lost or stolen. Further, most camera-based approaches limit the area where users can interact.
