The name Surface comes from "surface computing", and Microsoft envisions the coffee-table machine as the first of many such devices. Surface computing uses a blend of wireless protocols, special machine-readable tags and shape recognition to seamlessly merge the real and the virtual world. The term "surface" describes how it's used. There is no keyboard or mouse. All interactions with the computer are done via touching the surface of the computer's screen with hands or brushes, or via wireless interaction with devices such as smart phones, digital cameras. But it has limitation of sensing the object so, we have to introduce new technology which provide better sensing mechanism. Here, We represent new type of interactive surface technology based on a switchable projection screen which can be made diffuse or clear under electronic control. The screen can be continuously switched between these two states so quickly that the change is imperceptible to the human eye.
