1. An interactive system comprising:
- an source assembly for illuminating an exposed interface surface that is exposed to a user, with substantially uniform illumination;
a diffuser for diffusing illumination;
an detection system for capturing an image of said exposed interface surface through said diffuser, said detection system providing image data that is representative of illumination intensity of said exposed interface surface; and
a data filter for filtering said image data to provide filtered image data that identifies areas that include rapid transitions in intensity at their edges.

Abstract
An interactive system is disclosed that includes an infrared source assembly for illuminating an exposed interface surface that is exposed to a user with substantially uniform infrared illumination, a diffuser for diffusing infrared illumination, and an infrared detection system for capturing an infrared image of the exposed interface surface through the diffuser. The infrared detection system provides image data that is representative of infrared illumination intensity of the exposed interface surface.

11. An interactive system comprising:
-
an interface surface through which a user may interact with said interactive system from an exposed side of said interface surface;
an infrared source assembly for illuminating said interface surface with substantially uniform infrared illumination from an interior side of said interface surface; and
an infrared detection system for capturing an infrared image of said exposed surface from said interior side of said interface surface, said infrared detection system providing filtered image data that is representative of infrared illumination intensity of said exposed surface in areas that include rapid transitions in intensity at their edges. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A method of providing an interactive system, said method comprising the steps of:
-
providing an exposed interface surface through which a user may interact with said interactive system illuminating said exposed interface surface with substantially uniform infrared illumination;
capturing an infrared image of said exposed surface and producing captured infrared image data;
filtering background data from said captured infrared image data; and
applying a high pass filter to said captured image data to provide filtered image data that identifies areas that include rapid transitions in intensity at their edges. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 30)
