How Microsoft surface configured?

Surface computing is the term for the use of a specialized computer GUI in which traditional GUI elements are replaced by intuitive, everyday objects. Instead of a keyboard and mouse, the user interacts directly with a touch-sensitive screen. It has been said that this more closely replicates the familiar hands-on experience of everyday object manipulation.

1)) Screen:

A diffuser turns the surface's acrylic tabletop into a large horizontal " Multi touch " screen, capable of processing multiple inputs from multiple users. The surface can also recognize objects by their shapes..

 2)) Infrared :

Surface's "machine vision" operates in the near-infrared spectrum, using an 850 nanometer wavelength LED light source aimed at the screen. When objects touch the tabletop, the light reflects back and is picked up by multiple infrared cameras with a net resolution of 1280 * 960.

3)) cpu :

Processor: Core 2 Duo processor

RAM : 2GB

Graphics card : 256MB

Wi-fi

Bluetooth

Operating system is modified version of Microsoft Vista

4)) Projector :

Microsoft’s Surface uses the same DLP light engine found in many rear-projection HDTVs. The footprint of the visible light screen, at 1024 * 768 pixels , is actually smaller than the invisible overlapping infrared projection to allow for better recognition at the edges of the screen.
