String-based haptic interface device for multi-fingers

We propose a novel two-handed multi-finger haptic interface device. This system is another kind of string based hand haptic display system. DC motors, rotary encoders, pulleys, and strings are used to measure the position of eight fingertips of the user in real time. When any fingertip comes into contact with any virtual object, the system will control the tension of the strings pulled by the motors to display force feedback at that fingertip of the user. We briefly describe the system as well as the methods used for calculation of the fingertip positions and the generation of force feedback
