VarTech’s Optical Imaging touch screen technology, VOI, uses scanning optical cameras to sense a 2-dimensional 'field' which, when interrupted by a touch, uses sophisticated algorithms to return a point coordinate. VOI uses no surface coating so it doesnt degrade the image quality in any way. This also means surface scratches and contamination will not affect the touch screen performance. VOI provides touch sensitivity to the entire screen, corners included, and accuracy is guaranteed. VOI requires only one calibration because there is no drift with optical imaging technology.
