Microsoft's new virtual accessory for xbox 360 where unlike the wii, you actually move your WHOLE body. The kinect device has two camaras, a laser, and a motor so it can move its head up and down to look at you. it detecs your motion and body. don't listen to what any of the other insulting definitions say.
Microsoft's next accessory (or necessity) for their newest gaming console, Xbox One (ton). It can recognize your voice (probably as good as Windows voice recognition can), Skype someone (while you're trying to watch a movie), and detect your movements so you can play games or navigate with it! (Probably really crappy games and an even crappier Windows 8 styled User Interface) It will probably become the NSA's new mastuerbation machine.
Kinect 2.0? Hmm...I should consider getting a job at the NSA.
