Summary: We developed a haptic display that drives the skin via a lightweight belt with a DC motor. AC signals to the two DC motors generated vibration of the belt, and the vibration is directly presented to the skin in contact with the belt, while DC signals to the motors wind up the belt, and force sense is presented by causing skin deformation. By combining these two driving modes, high-fidelity vibration and directional force sensation can be presented simultaneously, with compact and low energy setups, which can be extended to various parts of the body.
