"Mouseless is a project by Pranav Mistry of the MIT Fluid Interfaces Group. He calls it an "invisible computer mouse" that creates the feeling of using a mouse without actually having a physical device. This is achieved via an infrared beam and sensor, which will help detect the hand's position. So all that's left for the user to do is move a cupped hand as if it were holding a mouse and the system will detect its movement and clicks." - Lit

Yeah, somebody might also be working on developing a monitor-less monitor that will only become visible when you touch it. I just love these kind of high-sci-fi concepts. - Avinash

Haha, did you check out the video? It's somewhat similar to the motion technology Sony and other gaming platform makers are working on/releasing. - Lit

Currently from the video the lag is a little much, but this is an interesting idea... - Chieze Okoye

Yeah, I know - Lit
