This touchscreen monitor, based on technology from TouchKo was recently demonstrated at the CeBIT show. The touchscreen monitor basically works without actually touching it. Basically, users swipe their hand from a distance of up to 15cm away and the built-in sensors translate that movement into a command like flipping pages, etc. So, clearly this is meant for medical purposes.
