Last night saw the midnight release of Microsoft's Kinect, the Xbox 360's much-advertised motion-sensing peripheral. Fans lined up days in advance at some locations, with a flagship launch event held in Times Square. Offering a "controller-free gaming experience," the sensor unit utilizes motion capture as well as facial and voice recognition to provide hands-free control of the Xbox. A standalone unit retails for $149.99 or comes bundled with a console for $299.99, and initial preorders and sales away from the launch, it is not uncommon in webcams to have facial detection issues. Especially when using low-resolution cameras, dark skin tones can be harder to detect and track, something that has troubled other webcam makers in the past. Microsoft is asking for anyone experiencing a problem to contact them via email and stresses that the system is designed to work with people of all shapes and ethnicities.
