Microsoft Surface

Microsoft Surface is a surface computing platform that responds to natural hand gestures and real world objects. It has a 360-degree user interface, a 30-inch reflective surface with a XGA DLP projector underneath the surface which projects an image onto its underside, while five cameras in the machine's housing record reflections of infrared light from objects and human fingertips on the surface. The surface is capable of object recognition, object/finger orientation recognition and tracking, and is multi-touch and is multi-user. Users can interact with the machine by touching or dragging their fingertips and objects such as paintbrushes across the screen, or by placing and moving placed objects. This paradigm of interaction with computers is known as a natural user interface (NUI).

Using the specially-designed barcode-style "Surface tags" on objects, Microsoft Surface can offer a variety of features, for example automatically offering additional wine choices tailored to the dinner being eaten based on the type of wine set on the Surface, or in conjunction with a password, offering user authentication.
