Window: userproximity event
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
userproximityevent is fired when fresh data is available from a proximity sensor (indicates whether the nearby object is near the device or not).
