This paper describes a Pseudo-Haptic rendering method for presenting torsional torques with a haptic interface. The pseudo-haptic torque is calculated based on a motion equation of a virtual object, which includes a viscous resistance when the virtual object is rotated. We have developed a one degree-of-freedom haptic interface equipped with a DC servomotor and a rotary encoder as a prototype system. Through experiments for comparing the pseudo-haptic rendering method, real haptic method, and, combination of these haptic rendering methods, effectiveness of the proposed method was verified.
