Kinect Technology
The Kinect technology was developed by Microsoft as "Project Natal" and was based upon a sensory system created by PrimeSense, a company in Tel Aviv.
A projector floods the room with near-infrared light and captures the reflected rays. Complex algorithms then convert the data into a three-dimensional mapping of the area. It then processes this information with data collected from other sensors to identify and recognize everything in the room.
Although this technology may be the ultimate in game gadgets, Microsoft believes it is the just the beginning of something even more innovative.
Electromagnetic fields permeate our homes, our vehicles, and our neighborhoods because of electricity. Researchers have discovered a way for electromagnetic field frequencies to identify and recognize us.
What this means is that you may soon be able to control anything electrical in your home with the wink of an eye, flick of a finger, uttering of a word, or whatever gesture you prefer.
