The brain localizes body parts in their perceived visual locations. The brain can, however, be easily fooled. By making use of the Rubber Hand Illusion (RHI), a feeling of ownership of the rubber hand can be evoked. The influence of this illusion on grasp force has not yet been researched, but it might well prove promising for grasp control during...
Conference Paper
During laparoscopic grasping, excessive grasp forces and tissue slippage may well lead to tissue damage. Because surgeons have difficulty gauging the force exerted on the grasped tissue, it is desirable to train them in applying the right degree of force in order to prevent tissue damage. Previously it was demonstrated that grasp force control can...
