Lcd Touch

Abstract:

We were interested in recent developments of multi-touch screens. So far, these screens use video projection (front or rear). We propose a new technology to reduce the volume significantly and increase the resolution of multi-touch screens. For this purpose, we use an LCD matrix identical to that used on modern computer monitors and one or more cameras with infrared (s) wide-angle lenses (up to 180°).
