Neonode started as a mobile phone company in Sweden and now focuses on developing, licensing, and selling their patented optical touch technology called zForce. ZForce uses an invisible grid of infrared light beams to detect touches on any surface like a finger or stylus. It provides advantages over other touch technologies by working with any screen shape and material and detecting touches from any object. The technology senses touch location, size, pressure, and speed using infrared emitters, detectors, and control software to calculate touch positions.
