Natural user interface (computers)
From Conservapedia
A natural user interface, often called a NUI, is a type of computer interface design that interacts with the user. Unlike the physical actions needed to control a GUI, the NUI optically recognizes objects and can display content based on voice and gestures. Surface computing is an example of a NUI interface. Microsoft Xbox Kinect is a platform for motion-based gestures that a NUI can interpret.
