Abstract
An electronic device receives inputs using images of input devices and scanning sensors that detect user interaction with those images. For example, an image of a mouse may be projected and the user's interaction with that image may be scanned using digital video cameras. These user movement images may then be analyzed to determine, for example, the direction, extent and rate of movement of the user to provide pointer position command signals. Similarly the user's movement relative to a virtual keyboard image may be analyzed and converted into key actuation signals for responding to the actuated virtual keys.
