Five cameras sense nearby objects so users can interact with the machine by touching or dragging their fingertips across the screen, or by placing objects such as plates and cutlery tagged with special bar codes labels.

Unlike most touchscreens, Surface can respond to more than one touch a time. The intuitive user interface works without a mouse or keyboard, giving people direct interaction with digital content.
Some of the first Surface models are planned to help customers pick out new mobile phones. When customers place a phone down on the table, Surface will read its bar code and display information about the handset. Customer can also select calling plans and ring tones by dragging icons toward the phone. Guest sitting in some hotel lobbies will be able to cluster around the surface to play music, then buy songs using a credit card or rewards card tagged with a bar code.
In some hotel restaurants, customers will be able to order food and drinks, then split the bill by setting down a card or a room key and dragging their menu items onto the card. Visit Microsoft Surface (Site takes some time to load, so have patience)
