Abstract
A system and method is provided for a gesture recognition interface system. The system comprises a projector configured to project colorless light and visible images onto a background surface. The projection of the colorless light can be interleaved with the projection of the visible images. The system also comprises at least one camera configured to receive a plurality of images based on a reflected light contrast difference between the background surface and a sensorless input object during projection of the colorless light. The system further comprises a controller configured to determine a given input gesture based on changes in relative locations of the sensorless input object in the plurality of images, and being further configured to initiate a device input associated with the given input gesture.
