The new Kinect is using a time of flight camera to improve motion sensing. This was from a MS blog. It seems reports are somewhat scarce about the new Kinect, they are slowly building the hype on this.
A time-of-flight camera emits light signals and then measures how long it takes them to return. That needs to be accurate to 1/10,000,000,000 of a second—remember, we’re talking the speed of light here. With such measurements, the camera is able to differentiate light reflecting from objects in a room and the surrounding environment. That provides an accurate depth estimation that enables the shape of those objects to be computed.
That speed-of-light capability would be a major advancement for the Kinect sensor portion of Xbox One
“Motion blur,” Acharya explains, “is a parameter that needs to be minimized and is not technology-specific. The time-of-flight camera uses global shutter, which has helped reduce motion blur significantly—from 65 milliseconds in the original Kinect to fewer than 14 milliseconds now.”
They mentioned this in the Reveal back in may, but it was drowned out by the parade of TVTVTSHPAWTZTVDOG memes. They also mentioned that it was Patented too... Which I am sure they must have some bloody good lawyers if they want to pull off a speed-of-light patent :p --- Purveyor of pixelated pornography since 1984 http://cdn.list25.com/wp-content/uploads/2011/11/aboss.gif
