What use would this controller be in an online multi-user virtual world given the constraints of latency, bandwidth, etc.? - SuezanneC Baskerville

If you mean the camera, I guess it can work just as quick as a mouse, when it knows what to send it the server. Not sure about bandwidth, but I think it wouldn't have to use much bandwidth. But they aren't actually using a normal webcam but a 3D camera, with 2 lenses. Which will slow adoption of this specific technology. Also most of use sit behind a desk when in a Virtual world, most people wouldn't want or have the room available to stand a few meters away infront of a big screen monitor. It cool tech but I'm not sure it will be adopted quickly. Philip's snowglobe project is going to try next to use your normal webcam to send over facial expression to your avatar which is a lot more interesting because most of us have a webcam and you can just keep sitting behind your desk. - Frans
