The invention relates to a design method of a visual tracking interface on a 3G (The 3rd Generation Telecommunication) mobile terminal, which is the application of a
machine vision technology on 3G mobile terminals. The interaction of motions and postures of human limbs with a 3G
mobile phone is natural, but a vision
algorithm on a traditional PC (
Personal Computer) platform has large calculation cost and cannot obtain real-time interaction effects in the application of the mobile terminals. In the method, a TMS3 20DM6467
chip based on dicaryon is adopted to share the cost of a
visual motion tracking and identifying
algorithm, which obtains interactive real time on a mobile platform. An
image sequence of limb motions is acquired by utilizing equipment such as a camera, and the like on the mobile platform on the basis of a visual user limb motion tracking
interactive technology, static or dynamic limb characteristics are extracted and limb gestures or actions are identified through a visual
algorithm so as to figure out the intention of a user and realize the man-
machine interaction. The method has wide application prospect in the fields of intelligent interaction,
recreational games, wearable computing, and the like of 3G mobile terminals.
