Abstract
The present invention is a system and method for detecting and analyzing motion patterns of individuals present at a multimedia computer terminal from a stream of video frames generated by a video camera and the method of providing visual feedback of the extracted information to aid the interaction process between a user and the system. The method allows multiple people to be present in front of the computer terminal and yet allow one active user to make selections on the computer display. Thus the invention can be used as method for contact-free human-computer interaction in a public place, where the computer terminal can be positioned in a variety of configurations including behind a transparent glass window or at a height or location where the user cannot touch the terminal physically.
