Instructions
Place moving pads underneath the legs of your chairs and sofa. This will allow you to slide them easily out of the way, to make more room for you to play Kinect.
Move a coffee table or any other items away from the middle of your room. A table or other object will interfere with the Kinect sensor and take up vital playing area.
Mount your television on the wall, if it's a flat screen. This allows you to free up a large amount of space in your room, giving you a much bigger area to use.
Use a Kinect zoom device, placing it over the Kinect sensor. This will zoom the lens, making your room dimensions seem bigger to the sensor than they actually are. So you can play on the Kinect with a much smaller space.
