1. An electronic input device comprising:
- a sensor system capable of providing information for approximating a position of an object contacting a surface over an active sensing area; and
a projector capable of displaying an image onto a projection area on the surface, wherein the image indicates one or more input areas where placement of an object is to have a corresponding input; and
wherein at least one of the sensor system and the projector are oriented so that the image appears within an intersection of the active sensing area and the projection area.

Abstract
A light-generated input interface is provided using a combination of components that include a projector and a sensor. The projector displays an image corresponding to an input device. The sensor can be used to detect selection of input based on contact by a user-controlled object with displayed regions of the projected input device. An intersection of a projection area and an active sensor area on a surface where the input device is to be displayed is used to set a dimension of an image of the input device.
