Pseudo-Haptic

ph0.jpg
A pseudo-torsional torque rendering method based on a motion equation of a virtual object is proposed.

A prototype system consists of a monitor, a PC, and a haptic interface. The interface has a haptic knob for sensing a user ’s twist motion and generating a real torque if necessary.

The pseudo-torsional torque is calculated based on a physical model of interaction between a virtual object and the user's ngertip. When the user rotates the virtual object, the user can feel the pseudo-torque. By adding the real torque generated by the interface, the intensity of the torque, which is felt by the user, is increased.
