IR Touch Kits
Infrared touch technology makes use of infrared light beams to detect the touch. A matrix of infrared beams ray over the panel. When an object blocks a light beam, a phototransistor will detect that and register the location of the touch. The technology features multi touch availability, can work on larger panels and can detect wet fingers or dirty gloves. IR touch kits can detect anything that can block the lights, so it is highly susceptible for the wrong detection of dust or insects. Direct sunlight can also affect the sensing capability.
