It seems like you think know everything, except you choose to ignore the technology in Project Natal. Why would you do that? Instead of aguing with me about it and stating as fact that it does not contain a 3D camera, why don't you do the basic research? You bothered to post a reply here, why not also do a quick search on the subject to get more up to speed?
I realize you are very anti-MS, but that is no reason to be in denial about the technology in Project Natal. It doesn't take much searching to find all sorts of information about the camera technology in Natal, which proves you 100% wrong. Since you refuse to do that little bit of reaserch, I'll do it for you, and hopefully you will stop being in denial.
"The 3D sensor itself is a pretty incredible piece of equipment providing detailed 3D information about the environment similar to very expensive laser range finding systems but at a tiny fraction of the cost. Depth cameras provide you with a point cloud of the surface of objects that is fairly insensitive to various lighting conditions allowing you to do things that are simply impossible with a normal camera.
But once you have the 3D information, you then have to interpret that cloud of points as "people". This is where the researcher jaws stay dropped. The human tracking algorithms that the teams have developed are well ahead of the state of the art in computer vision in this domain. The sophistication and performance of the algorithms rival or exceed anything that I've seen in academic research, never mind a consumer product."
"The device features an "RGB camera, depth sensor, multi-array microphone, and custom processor running proprietary software", which provides full-body 3D motion capture, facial recognition, and voice recognition capabilities. The Project Natal sensor's microphone array enables the Xbox 360 to conduct acoustic source localization and ambient noise suppression, allowing for things such as headset-free party chat over Xbox Live.
The depth sensor consists of an infrared projector combined with a monochrome CMOS sensor, and allows the Project Natal sensor to see in 3D under any ambient light conditions. The active depth-sensing range of the depth sensor is adjustable, with the Project Natal software capable of automatically calibrating the sensor based on the gameplay and environment conditions, such as the presence of couches."
This link shows a video demo of the depth camera that was created by 3DV Systems, which is the company MS bought to get the hardware for Project Natal. BTW, research into Project Natal was going on years before they bought 3DV Systems. It is much more than just the 3D camera.
An interview with Shane Kim, corporate vice president for strategy and business development at Microsoft’s game division:
"It uses an RGB camera (image sensor), a 3-D depth camera (which determines how far away an object is from the camera), and a multi-array microphone."
Sorry, I know it includes a "range finder". I am still skepetical this will be accurate without any information regarding how this range finder actually works. If Microsoft managed to reduce the cost of a product by an order of mangitude overnight, and doesn't explain HOW, I don't think I am being unreasonable by questioning it. If that makes me "very anti-MS" then so be it.
