Display of Feel for the Manipulation of Dynamic Virtual Objects

A system for displaying feel information, while manipulating virtual objects, which takes their dynamic behavior into account is introduced. The display is realized using multiple link mechanisms. New concept of impedance display and two ways of its realization, “measuring force and displaying motion” and “measuring motion and displaying force,” are proposed. Calculation algorithms for the driving input to the display device for the operation of both single-body and multi-body virtual objects are established. The validity of the proposed method is verified experimentally using a newly developed two-finger display device.
