Lift: Millimeter-level finger tracking with Arduino and light sensors

Friday, April 21st, 2017

Researchers at the UC Irvine and the FX Palo Alto Laboratory present Lift, a visible light-enabled finger tracking: By projecting encoded visible patterns onto an object’s surface (e.g. paper, display, or table), and localizing the user’s fingers with light sensors, Lift offers users a richer interactive space than the device’s...
