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.
