Surface Computing Using Htm: a Gesture Recognition and Tracking Framework Saad Aftab

Natural user interface, or NUI, is the common parlance used by designers and developers of computer interfaces to refer to a user interface that is effectively invisible, or becomes invisible with successive learned interactions, to its users. The word natural is used because most computer interfaces use artificial control devices whose operation has to be learned. A NUI relies on a user being able to carry out relatively natural motions, movements or gestures that they quickly discover control the computer application or manipulate the onscreen content. The most descriptive identifier of a NUI is the lack of a physical keyboard and/or mouse.
