SYSTEMS AND METHODS FOR PROVIDING NORMALIZED PARAMETERS OF MOTIONS OF OBJECTS IN THREE-DIMENSIONAL SPACE
First Claim
1. A method of tracking a movement of an object in 3D space, the method comprising:
- capturing a plurality of temporally sequential images of the object within the 3D space;
defining a detection zone in the 3D space, the detection zone including at least a portion of the object;
computationally analyzing the images to determine movement parameters associated with the object portion movement within the detection zone; and
computationally scaling the movement parameters to generate normalized parameters relative to the detection zone.

Abstract
Systems and methods are disclosed for detecting user gestures using detection zones to save computational time and cost and/or to provide normalized position-based parameters, such as position coordinates or movement vectors. The detection zones may be established explicitly by a user or a computer application, or may instead be determined from the user'"'"'s pattern of gestural activity. The detection zones may have three-dimensional (3D) boundaries or may be two-dimensional (2D) frames. The size and location of the detection zone may be adjusted based on the distance and direction between the user and the motion-capture system.
