This is pretty cool! A laser beam and infrared camera produce an invisible mouse! In the words of the inventor Pranav Mistry:
“Mouseless is an invisible computer mouse that provides the familiarity of interaction of a physical mouse without actually needing a real hardware mouse”.
Professor Randy says: I personally love the mouse that I am currently using (Microsoft Wireless Mouse 5000), but I think that this concept is interesting and should develop into bigger and better things!
