Zusammenfassung:An apparatus for detecting user interaction or another input with a projected display includes a boundary definition mechanism and a scanning mechanism. The boundary definition mechanism is capable of defining at least one input region. The scanning mechanism is capable of scanning the at least one input region for any objects therein. An input identification mechanism may identify the input identified by the object, movement of the object, or a change in the object's position. That information may be used to alter the projected display.
