A six degree of freedom force reflecting haptic interface includes three powered axes and three free axes, all of which are tracked so that the position of a user connection element in the work volume can be determined. The interface includes cable drives with polymer composite or metallic cables, automatic cable tensioning devices, and grounded actuator capstans. A nested hub and transfer drive provide a compact, weight balanced interface. User comfort and safety features are also provided.

Force reflecting haptic interface

A trophotropic response system which aids a user in achieving a relaxation response. In one embodiment the system includes a control unit and an audio-visual unit. The control unit includes a processor and associated hardware and software to control the audio-visual unit. The audio-visual unit includes a light producing unit having a pair of earphones coupled thereto. The light producing unit includes a plurality of light sources which direct light toward a diffuser screen disposed between the eyes of a user and the light sources. This arrangement permits the user to see light from the light sources diffused over a large visual angle. The light sources produce light and the earphones produce sound in response to audio and light control signals provided by the processor of the control unit. The signal characteristics of the light and sound control signals may be varied within predefined limits to aid the user in performing a relaxation exercise.
