Sparkle

Hover Feedback with Touchable Electric Arcs

Abstract


Sparkle stimulates the fingertip with touchable electric arcs above a hover sensing input device. We use a high voltage resonant transformer and a self-resonating circuit for which we control the electric discharge to create in-air tactile and thermal sensations up to 6 mm in height, and combined this technology with infrared proximity sensing. Sparkle is the first step towards providing a new type of in-air feedback for hover input without requiring users to wear tactile stimulators.
