WHY KINECT?
Full Body Gaming.
Something For Everyone.
It’s All About You.
WORKING OF KINECT
The Kinect uses structured light & machine learning .
Inferring body position is a two-stage process: first compute a depth map (using structured light), then infer body position (using machine learning)
Stage 1: The depth map is constructed by analyzing a speckle pattern of infrared laser light.
The technique of analyzing a known pattern is called structured light .
The Kinect uses an infrared projector and sensor; it does not use its RGB camera for depth computation.
The Kinect combines structured light with two classic computer vision techniques: depth from focus, and depth from stereo.
Depth from stereo uses parallax .
If you look at the scene from another angle, stuff that is close gets shifted to the side more than stuff that is far away .
The Kinect analyzes the shift of the speckle pattern by projecting from one location and observing from another .
CONCLUSION
By integrating all these techniques to a single console, kinect act as a perfect device for creating a virtual reality for the user.
Several project researches are now carried out using Kinect as the main tracking device.
Kinect is not just a gaming console, but also an eye to a computer.
