Microsoft has allowed the public to get their hands on its new hands-free games controller for the first time.
The US firm showed off the "Natal" technology, designed for use with its Xbox 360 console, at the European games convention gamescom in Germany.
The controller uses a microphone combined with visual and infrared cameras to control the onscreen action.
It was first unveiled at the E3 Expo in Los Angeles in June this year, but had not been on public display until now.
Kudo Tsunoda, Xbox 360's general manager and creative director of Natal, said that as consoles evolved from being a dedicated games machine into "living room entertainment", it was important to develop a new control interface.
