Revel: Programming the Sense of Touch

Revel: Programming the Sense of Touch: Reverse-Electrovibration.



 '' Revel is a new wearable tactile technology that modifies the user’s tactile perception of the physical world. Current tactile technologies enhance objects and devices with various actuators to create rich tactile sensations, limiting the experience to the interaction with instrumented devices. ... Revel is based on Reverse-Electrovibration. It applies a weak electrical signal anywhere on the user’s body, creating an oscillating electrical field around the user’s skin. When sliding one's 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, such as the shape, amplitude and frequency, can provide a wide range of tactile sensations. ''
