Fooling the sense of touch with tactile technology
REVEL is a new wearable tactile technology that modifies the user’s tactile perception of the physical world. It can add a layer of artificial tactile texture to almost any surface or object, with very little if any instrumentation of the environment. As a result, REVEL can provide dynamic tactile sensations on touch screens as well as furniture, walls, wooden and plastic objects, and even human skin.
REVEL is based on Reverse Electrovibration. It injects a weak electrical signal into anywhere on the user’s body, creating an oscillating electrical field around the user’s skin. When sliding his or her fingers on a surface of the object, the user perceives highly distinctive tactile textures that augment the physical object. Varying the properties of the signal provides a wide range of tactile sensations.
