Kinect 2.0 (Xbox One)
All Xbox One consoles will be shipped with a new and updated version of Kinect. The new device has a 1080p camera and processes 2 gigbits of data per second to read the enviroment. The new Kinect has greater accuracy with three times fidelity of the previous 1.0. It even has the abilty to see in the dark, thanks to a new IR sensor. It has a 60% wider field of vision; which can detect the user up to 3 feet from the sensor. It will also have the ability to detect six players at once. The new device can also detect the players heart rate, facial expression, 25 joints (including thumbs) and the precise rotation of such joints. In early 2013, the Xbox One was said to require the Kinect 2.0 to be connected at all times to operate. However, due to a large amount of critisim, Microsoft later decided to change this policy.
