Patent Number: 6431711 
Title: Multiple-Surface Display Projector With Interactive Input Capability 
Abstract: The present invention projects an image onto any surface in a room and distorts the image before projection so that a projected version of the image will not be distorted. The surface could be planar or non-planar. The present invention also allows for a projected image to be displayed at multiple locations along a surface or multiple surfaces. This allows a projected image to move from one location on a surface to another location on this or another surface, while the projected image remains undistorted through the move. Moreover, the present invention allows interaction between people and a projector. Interactive input, such as from mice, may be used with the versions of the present invention. Importantly, versions of the present invention can determine if an object is near an interactive item (such as a hyperlink) on the projected image. If so, the present invention can activate the interactive item. This allows a person to interact with a projected image.
