Gesture Recognition Light and Video Image Projector
First Claim
1. A gesture recognition interface system comprising:
- a projector configured to project colorless light and visible images onto a background surface, the projection of the colorless light being interleaved with the projection of the visible images;
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; and
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.

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.

12. A method of providing device inputs, the method comprising:
-
projecting non-visible light interleaved with visible images onto a background surface; providing simulated inputs over the background surface via gestures associated with a sensorless input object; generating a plurality of images associated with the sensorless input object based on a reflected light contrast between the sensorless input object and the non-visible light; determining a plurality of three-dimensional physical locations of the sensorless input object relative to the background surface; determining if changes in the plurality of three-dimensional physical locations of the sensorless input object correspond to a given one of a plurality of predefined gestures; and providing at least one device input based on determining that the changes in the plurality of three-dimensional physical locations of the sensorless input object correspond to the given one of the plurality of predefined gestures. - View Dependent Claims (13, 14, 15, 16)

17. A gesture recognition interface system comprising:
-
means for projecting non-visible light interleaved with visible images onto a background surface; means for generating a plurality of images of a sensorless input object based on a brightness contrast between the background surface and the sensorless input object; means for generating three-dimensional location information associated with the sensorless input object based on the plurality of images of the sensorless input object; means for translating changes in the three-dimensional location information associated with the sensorless input object to a given input gesture; and means for providing device inputs based on matching the given input gesture with one of a plurality of predefined gestures. - View Dependent Claims (18, 19, 20)
