Abstract

A system and method are disclosed for providing a touch interface for electronic devices. The touch interface can be any surface. As one example, a table top can be used as a touch sensitive interface. In one embodiment, the system determines a touch region of the surface, and correlates that touch region to a display of an electronic device for which input is provided. The system may have a 3D camera that identifies the relative position of a user's hands to the touch region to allow for user input. Note that the user's hands do not occlude the display. The system may render a representation of the user's hand on the display in order for the user to interact with elements on the display screen.
