Patent ID: 7961174

Claim:
A processor-implemented method for tracking multiple people in a motion capture system, comprising the processor-implemented steps of: using the motion capture system, tracking at least one group which includes a first group, the first group comprises peoples' bodies in a field of view of the motion capture system, the tracking includes detecting the peoples' bodies, including sizes of the peoples' bodies, in the field of view; based on the tracking, detecting representative locations of the peoples' bodies in the field of view, detecting a point location of the first group as a first unitary entity based on the representative locations of the peoples' bodies in the field of view, and determining movement of the point location of the first group as the first unitary entity based on movement of the representative locations of the peoples' bodies in the field of view; and providing inputs to an application which are based on the movement of the point location of the first group, the application displays a virtual space on a display, and updates the display based on the inputs.
