: The growing number of robotics application fields, mainly in services, has led to the increase of new needs as well as the development of new facilities for teleoperation. Research in the design of more efficient and easy to use human-machine interfaces has propitiated the development of friendly communication systems such as those based on voice or gesture recognition. This work describes a vision based human-machine communication system that allows a computer or a control unit to "see and track" the position of the hands of a human. Thus, the vision system can be used as a virtual exoskeleton for simple telemanipulation tasks.
