By plugging it into your Xbox, and if you don't have the Xbox slim, you also need to plug it into an electrical outlet.
No, you must turn it on using the button or the controller
First of all, do you have the Kinect. The Kinect has a built in microphone so you can command your xbox with voice. I have an xbox 360 (slim 250 GB) and a Kinect but I don't think you can switch it on by voice.
Unplug it ... -.-
Yes. Kinect games are ONLY for the Kinect...
Kinect can come with Kinect Adventures
The Kinect for Xbox 360
No. It will include Kinect but it won't be Kinect-only.
Kinect
There is WWE on Kinect
you can only play kinect games on the kinect
No you cant, if you see games that says the word kinect on the top right corner then its a kinect game. or if you see a sticker that's purple and shows the kinect and says requires kinect sensor then its a kinect game.
Yes, but if you want to get all technical you could say that kinect is the system and the kinect sensor is, well, the sensor. But if you buy the kinect, you are buying both.
