This paper's research subject is: Captures the human body upper part plane movement to have 7 different position data, the use identification color material for the foundation method, after obtaining the coordinate, manufactures the character animation. And take the low cost way construction overall system as the consideration. The research expense only purchases the hardware equipment, may achieve the research goal. This research uses one web cam, penetrates the USB interface to input the phantom to the system main engine, by way of colored phantom coordinates processing, the sub-area principle analyzes on the identification human body the color mark position. We regarding the experimental result which picks up carry on the discussion, and realizes in the simple character animation manufacture.
