![]() ![]() A 3GHz clock rate, for instance, can measure distances with an accuracy of about 2 inches, enough to get a pretty good idea of how a human body is oriented and what it’s doing. Again, processor speeds only reached the point where this could be performed economically in consumer-market gear fairly recently. Kinect Teardown Reveals IR Projector, Fan. Since light travels at a very precisely-known speed (covering about a foot every one billionth of a second), measuring that time gives you the distance to the subject. The Kinect, which went on sale yesterday, is a controller-free controller for the Xbox 360. In this case, the light source flashes at regular intervals, and the individual pixels of the camera measure how long it takes the light to reach the subject at a given location, get reflected, and return - kind of like sonar. The basic hardware used in this method is very similar to the structured-light system - it just needs a light source and a camera. This model abandoned the IR-based structured light approach in favor of a time of flight camera. The Kinect for Xbox One used another method to produce data on the depth aspect of a scene. ![]()
