Haptic Display and Virtual Coupling

(1) The proposed virtual coupling was a virtual mechanical system interposed between the haptic interface and the virtual environment to limit the maximum or minimum impedance presented by the virtual environment in such a way as to guarantee stability.

(2) Haptic display: is a manner to transfert force or displacemnt information to users.
two classes: admittance and impetance based haptic display. 

(3) Just as we need a visual model for visual display,  a "Haptic Model" is necessary for haptic display.

There are three types of haptic rendering techniques:
  (1) Point-based haptic rendering;
  (2) Ray-based haptic rendering;
  (3) Oject-based haptic rendering.
