INTERACTIVE INPUT SYSTEM AND METHOD
First Claim
Patent Images
1. A method of resolving ambiguities between at least two pointers within a region of interest comprising:
- capturing images of the region of interest and at least one reflection thereof from different vantages using a plurality of imaging devices;
processing image data to identify a plurality of targets for the at least two pointers;
for each image, determining a state for each target and assigning a weight to the image data based on the state; and
calculating a pointer location for each of the at least two pointers based on the weighted image data.

Abstract
A method of resolving ambiguities between at least two pointers within a region of interest comprises capturing images of the region of interest and at least one reflection thereof from different vantages using a plurality of imaging devices, processing image data to identify a plurality of targets for the at least two pointers, for each image, determining a state for each target and assigning a weight to the image data based on the state, and calculating a pointer location for each of the at least two pointers based on the weighted image data.

6. An interactive input system comprising:
-
an input surface divided into at least two input areas; at least one mirror positioned with respect to the input surface and producing a reflection thereof, thereby defining at least two virtual input areas; a plurality of imaging devices having at least partially overlapping fields of view, the imaging devices being oriented so that different sets of imaging devices image the input area and virtual input areas; and processing structure processing image data acquired by the imaging devices to track the position of at least two pointers adjacent the input surface and resolving ambiguities between the pointers. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)

15. An interactive input system comprising:
a plurality of imaging devices having fields of view encompassing an input area and a virtual input area, the imaging devices being oriented so that different sets of imaging devices image different input regions of the input area and the virtual input area. - View Dependent Claims (16, 17, 18, 19)
