SCHEME FOR DETECTING AND TRACKING USER MANIPULATION OF A GAME CONTROLLER BODY AND FOR TRANSLATING MOVEMENTS THEREOF INTO INPUTS AND GAME COMMANDS

摘要

A method for use in obtaining information includes receiving on an image plane of a camera a projection of a geometric shape established on a controller (302), analyzing movements and deformities in the projection of the geometric shape (304), and determining position information for the controller based on the analysis of the movements and deformities in the projection of the geometric shape (306). A method for use in providing input to a system includes determining position information for a controller for the system (322), comparing the determined position information for the controller with predetermined position information associated with commands (324), and providing a command to the system if the determined position information matches predetermined position information for the command (326). A method for use in a game may include analyzing the position information to determine whether a predetermined movement of the controller associated with a command has been performed.
