You can use Kinect gestures to control the Xbox Dashboard instead of using a controller. To get the best Kinect experience, make sure that you have the latest console software.
Use gestures with the Xbox Dashboard
Hold your arm straight out to the side and bend your elbow upward.
Now wave your hand by moving your forearm left and right (Wave to Kinect).
Once you wave at the Xbox Dashboard, a hand cursor appears and you can now use gestures to navigate the Dashboard instead of a controller.
Point the palm of your hand toward the screen and move the on-screen hand over the item you want to select. To select an item, keep your hand over the item until the circle completes.
To move to the next area of the Xbox Dashboard, move your hand to the edge of the screen and “swipe” across your body.
How to start the Kinect Guide
Similar to the Xbox Guide, the Kinect Guide is a quick and easy way to start Kinect activities. You can view your friends, messages, achievements and troubleshoot Kinect sensor problems from the Kinect Guide.
Use the Guide gesture to start the Kinect Guide. Here's how:
Wave to Kinect to activate motion control.
Position both arms at your sides.
Now move your left arm straight out at a 45 degree angle from your body.
