Device Orientation

The device orientation events are useful for knowing what is the user doing with the device. You can use them for developing games or creating motion patterns.

Here's a little example that can be tested on your device using cordova or other webview.

  acceleration.x = e.gamma;
  acceleration.y = e.beta;
