Will gesture recognition technology point the way?

When playing most video games, speed is of the essence. Manipulating a joystick, mouse, or other input device slows a player's reaction time. Players prefer to control game activities by movements or gestures. Gesture-recognition systems identify human gestures and use them to convey information such as input data or to control devices and applications such as computers, games, PDAs, browsers, cell phones, and MP3 audio players. Researchers continue to improve gesture-recognition technology - for example, by making algorithms faster, more robust, and more accurate.
