Shadow Sense Touch (SST)
ShadowSense™ touch technology is an innovative and patented optical position sensing technology. ShadowSense designs use high-performance sensors operating in the analog domain to provide unprecedented performance, stability, and accuracy.
The best analogy for ShadowSense technology lies in the 6,000-year-old sundial. The shadow cast by a sundial instantly and accurately responds to the position of a light source without the use of lenses, with an infinite depth of field, and without the need for exposure control. ShadowSense technology exploits the same characteristics for touch applications, resulting in one of the highest performance, most robust optical sensing solutions available.
YouTouch utilizes the following shadowsense range from Baanto for their touchscreen displays
