Gesture Recognition - (3-dimensional Movement Recognition, Gesture-based Interactivity,
3D Gesture Recognition, Gesture-driven.) - Gesture Recognition makes it possible to control devices such as TVs, computers and video games, primarily with hand and/or finger movement. With this technology you can change television channels, adjust the volume, interact with others through your TV, etc. This technology uses synchronous camera input from the viewer's movement. 3D Gesture Recognition technology relies on a camera mounted on a TV or computer screen such as a web camera or 3D camera. Nintendo Wii made this type of technology popular in the world of gaming.
