Surface wave touch screen Elo TouchSystems SAW, IntelliTouch, SecureTouch
Using surface wave technology as its foundation, Elo has created a breakthrough in touch technology-iTouch. In Elo's new iTouch touch-on-tube technology, surface waves (also known as surface acoustic waves) are directed onto the cathode ray tube (CRT) surface itself for unhindered touch sensing-eliminating any glass overlay on the CRT and delivering the highest quality image possible.
