Have you ever wondered why computing experiences are still limited to specific devices such as Desktops, Laptops and Cell phones? Why the walls, tables or whiteboards around us do not function as computers which blend in our environments and we can interact with them seamlessly via touch and gestures?
Imagine a technology which can turn any flat surface in the world around you such as a wall, a whiteboard or a piece of furniture into a touch surface. Now further picture if this can be achieved with a sensor by just scanning at the surface from a distance - without adding any electronics in the surface itself?
