DualPanto is a haptic device that enables blind users to track moving objects while acting in a virtual world.
As shown in above figure (b), the device features two handles. Users interact with DualPanto by actively moving the me handle with one hand and passively holding on to the it handle with the other. DualPanto applications generally use the me handle to represent the user’s avatar in the virtual world and the it handle to represent some other moving entity, such as the opponent in a soccer game.
