Simulating Textured Surfaces
Called the WHaT (Wireless Haptic Texture Sensor), the pen-like device allows the user to "feel" the texture of surfaces that it is run over. Corduroy, sandpaper, beard stubble, polished surfaces and other distinctive textures can all be transmitted through the WHaT.
The possibilities for such haptic technology are endless. Telemedicine is one of the first to come to mind, as well as computing interfaces for visually impaired users.
