Natural User Interface (NUI)

According to Wikipedia, "In computing, a natural user interface, or NUI, or Natural Interface is the common parlance used by designers and developers of human-machine interfaces to refer to a user interface that is effectively invisible, and remains invisible as the user continuously learns increasingly complex interactions. 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 quickly transition from novice to expert. While the interface requires learning, that learning is eased through design which gives the user the feeling that they are instantly and continuously successful. Thus, “natural” refers to a goal in the user experience – that the interaction comes naturally, while interacting with the technology, rather than that the interface itself is natural. This is contrasted with the idea of an intuitive interface, referring to one that can be used without previous learning.".

Kinect is a device that is oriented to the NUI (Natural User Interface), because it helps users to interect to the Xbox (and computer) with gestures that they can do with their hands, head, arms, and the body in general. This technology can work even if there are other people in the room or if the lights are low (or there are no light).

Today, there are a few companies and developers that are doing applications for the Windows computers in several areas:

• Voice recognition
• Fashion
• Medical
• Music creation
• Education
• Marketing
