Force display systems are important in virtual reality and other applications. For force display system, it is the most important thing to ensure the safety mechanically in order to prevent operators from hurting. The conventional force display systems are active systems with actuators but these systems may become dangerous when going out of control. On the other hand, passive force display systems with only passive elements are thought to an effective method for assuring the inherent safety. In this paper, we evaluate force display ability about a 2-D passive-type force display system using fast-response MR (Magneto-Rheological) fluid brakes in order to apply this system to the virtual reality techniques and so on.
