Remember my blogpost at the end of may about the Microsoft Research innovation called Surface. Let me refresh your memory, Surface is a 30 inch tabletop which allow people to work without using any mouse or keyboard but just their hands. Wouldn't it be great to have this kind of technology on a laptop?
Steve Hodges from Microsoft Research in Cambridge might have the solution by using some infrared sensors on the back of his laptop screen.
