Concept: The prosthesis markers are tracked with the camera integrated into the AR glasses. This enables the evaluation of relative movements between the AR glasses and the prosthesis. A ray perpendicular to the glasses, defines the direction of view and is used as a pointer in the virtual command window attached to the prosthesis. The user can enter commands by moving the pointer over the command window.
