Computers always used as tools for the design and manipulation of three-dimensional objects, may soon offer people a way to feel the texture of objects or feel how they fit together, thanks to a haptic, or tap the basic interface developed at Carnegie Mellon University. Unlike most other haptic interfaces that are based on engines and mechanical linkages to provide some sense of touch or force, the device developed by Ralph Hollis, professor of research at the Institute of Robotics Carnegie Mellons,.

Unlike most other haptic interfaces that are based on engines and mechanical linkages to provide some sense of touch or force, the device developed by Ralph Hollis, professor of research at the Institute of Robotics Carnegie Mellons, and uses magnetic levitation one moving part to give users a realistic experience. Users can receive textures, contacts feel hard and notice even slight changes in position during use an interface that responds quickly to the movements.
