Claim One:
1. A gesture recognition method comprising: capturing images using imaging sensors having fields of view aimed generally across or at an input surface from different vantages; processing the captured images to detect a pair of hands brought into contact with said input surface and for each detected hand calculating a bounding box, the calculated bounding box surrounding either a cluster of proximate touch points resulting from multiple fingers of the hand being in contact with said input surface or a single large touch region exceeding a threshold size resulting from a palm region of the hand being in contact with said input surface; creating an observation for each bounding box in each captured image, each observation in each captured image defined by the area formed between two straight lines, one line of which extends from the focal point of the imaging sensor that captured the image and crosses the right edge of the bounding box and the other line of which extends from the focal point of the imaging sensor that captured the image and crosses the left edge of the bounding box; in response to relative movement of the hands over the input surface, recognizing a gesture based on corresponding relative movement of the created observations; executing a command associated with the recognized gesture; and updating an image displayed on said input surface in accordance with the executed command.
