Microsoft Surface,an emerging user experience

Surface computing brings an idea to use gestures, touch and physical objects to interact with the touch sensitive screen, that’s take input for further processing instead traditional mouse and keyboard.
User can interact directly with digital information and device recognizes many points of contact simultaneously and it also provides multi-User interaction opportunity.

Surface computing is attributed to Microsoft Corporation and released surface computing enable device say “Microsoft Surface”.

“Microsoft Surface turns an ordinary tabletop into a vibrant, interactive surface. It's the first commercially-available surface computing platform from Microsoft. The product provides effortless access to digital content through natural gestures, touch and physical objects. Today, it's a 30-inch diagonal display in a table-like form factor that's easy for individuals or multiple people to interact with in a way that feels familiar, just like in the real world”.

Simple to understand, how does it work?

(1)Screen There is a diffuser which turns the Surface’s acrylic tabletop into a large horizontal “multitouch” screen, which is capable of processing multiple inputs from multiple users. The Surface is so far advanced than we could imagine that it can recognize objects by their shapes or by reading coded “domino” tags when placed on the table.
(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 x 960.
(3)CPU Surface uses many of the same components found in everyday desktop computers — a Core 2 Duo processor, 2GB of RAM and a 256MB graphics card. Wireless communication with devices on the surface is handled using WiFi and Bluetooth antennas (future versions may incorporate RFID or Near Field Communications). The underlying operating system is a modified version of Microsoft Vista.
(4)Projector Microsoft’s Surface uses the same DLP light engine found in many rear-projection HDTV’s. The footprint of the visible light screen, at 1024 x 768 pixels, is actually smaller than the invisible overlapping infrared projection to allow for better recognition at the edges of the screen.

Today, Microsoft Surface is available in the retail, hospitality, automotive, banking and healthcare industries.
