First Claim
Patent Images
1. An interactive input system comprising:
- a bezel at least partially surrounding a region of interest, said bezel having a plurality of bands thereon with at least some adjacent bands having different optical properties;
at least one imaging device looking into said region of interest and seeing said at least one bezel so that acquired images comprise regions corresponding to said bands; and
processing structure processing pixels of a plurality of said regions to detect the existence of a pointer in said region of interest.

Abstract
An interactive input system comprises a bezel at least partially surrounding a region of interest. The bezel has a plurality of bands thereon with at least some adjacent bands having different optical properties. At least one imaging device looks into the region of interest and sees the at least one bezel so that acquired images comprise regions corresponding to the bands. Processing structure processes pixels of a plurality of the regions to detect the existence of a pointer in the region of interest
