Described by Microsoft personnel as the primary innovation of Project Natal, the software technology enables advanced gesture recognition, facial recognition, and voice recognition. The skeletal mapping technology shown at E3 2009 was capable of simultaneously tracking up to four users for motion analysis, with a feature extraction of 48 interest points on a human body at a frame rate of 30 hertz. Depending on the person's distance from the sensor, Project Natal is capable of tracking models that can identify individual fingers.
