Abstract
A system for defining a bounding box include one or more image projectors; one or more optical beam generators; a display surface; a computing element; and a digital image sensor. The digital image sensor is configured to sense a location of image orientation indicators generated by the optical beam generators. The computing element is configured to communicate with the digital image sensor to determine a bounding box defined by the locations of the image orientation indicators and to control the one or more image projectors to project an image in, and corresponding to, the bounding box on the display surface.
