REVEL is a new wearable tactile technology that
modifies the user’s tactile perception of the physical world. Current tactile
technologies limit the experience to the interaction with instrumented devices.
REVEL can add artificial tactile sensations to almost any surface or object,
with very little if any instrumentation of the environment. REVEL can provide
dynamic tactile sensations on touch screens as well as everyday objects and
surfaces in the environment.
REVEL is based on Reverse Electrovibration and
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, such as the shape, amplitude and frequency, can provide a wide
range of tactile sensations.
