INTERACTIVE INPUT SYSTEM AND BEZEL THEREFOR
First Claim
1. An interactive input system comprising:
- at least one imaging device having a field of view looking into a region of interest;
a bezel at least partially surrounding said region of interest and having a surface in the field of view of said at least one imaging device;
a first radiation source emitting radiation into said region of interact that is generally matched to the characteristics of said bezel so that the radiation emitted by said first radiation source is reflected by the bezel surface generally towards said at least one imaging device; and
a second radiation source emitting radiation into said region of interest that is generally unmatched to the characteristics of said bezel so that the radiation emitted by said second radiation source is not reflected by said bezel surface.

Abstract
An interactive input system comprises at least one imaging device having a field of view looking into a region of interest, a bezel at least partially surrounding the region of interest and having a surface in the field of view of the at least one imaging device, a first radiation source emitting radiation into the region of interact that is generally matched to the characteristics of the bezel so that the radiation emitted by the first radiation source is reflected by the bezel surface generally towards the at least one imaging device and a second radiation source emitting radiation into the region of interest that is generally unmatched to the characteristics of the bezel so that the radiation emitted by the second radiation source is not reflected by the bezel surface.
