Abstract
The methods and systems of the present invention receive video or image data, for example via television broadcast, cable, or satellite television signal, or directly from a video player, and process the data to determine the geometry and material properties of various objects represented in the video image. Geometry and material property information may be deciphered from a video image by reference to various fixed data sources and/or the application of known methods for elucidating such information from video or image data, such as shape-from-motion or shape-from-shading techniques. Alternatively, all or some of this information may be provided to the system together with the video or image data via a preconfigured side channel. The system coordinates and assembles the image data with the data relating to geometry and material properties of the objects and provides a realistic haptic interaction with those objects to the user.
