The realism of any virtual environment in which physical objects and forces are rendered depends on the fidelity of haptic displays.
Haptic displays provide information to a human user through the sense of touch.
For example, remote surgery via telerobot Dr. Dov Adelstein of Code IHH recently invented and patented a unique parallel mechanism suitable for high-fidelity haptic displays and controls. Unlike previous designs, Dov s mechanism uses a novel spatial linkage with a minimum number of rigid links an Research on human factors of virtual environments and haptic interfaces is a core element of the Human Factors Division.
