tactoRing is a novel smart ring that provides rich, yet subtle, discrete haptic feedback based on the high tactile resolution of the finger skin. tactoRing excites the skin by dragging a small movable actuator around the finger, directly in contact with the skin. This allows users to perceive tactile feedback in the form of motion applied to specific locations around the finger, with different speeds and directions. By controlling the ring through a separate device such as a mobile phone or a car navigation system, the ring can be used, for example, to convey street directions and caller IDs using motion.
