This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The DeviceOrientationEvent provides web developers with information from the physical orientation of the device running the web page.
Warning: Currently, Firefox and Chrome do not handle the coordinates the same way. Take care about this while using them.
Constructor

DeviceOrientationEvent.

DeviceOrientationEvent.betaRead only- A number representing the motion of the device around the x axis, express in degrees with values ranging from -180 to 180. This represents a front to back motion of the device.
DeviceOrientationEvent.gammaRead only- A number representing the motion of the device around the y axis, express in degrees with values ranging from -90 to 90. This represents a left to right motion of the device.

[1] Before version 50, Chrome provided absolute values instead of relative values for this event. Developers still needing absolute values may use the ondeviceorientationabsolute event.
[2] Firefox 3.6, 4, and 5 supported mozOrientation instead of the standard DeviceOrientationEvent interface
