Natural user interface

Natural User Interface (NUI) is a way of interacting with technology using your body. It's like talking to a computer without using a mouse or a keyboard. Instead, you use gestures like waving your hand or pointing at the screen to tell the computer what to do. For example, when you play the Xbox Kinect game, you don't need a controller. You can use motions like jumping, running, or punching to control the game.
