This feature is obsolete.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.

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The hasPosition read-only property of the VRPositionState interface returns a boolean indicating whether the VRPositionState.position property is valid (i.e. if the hardware is currently registering a valid position). If it is false, the position property will return null.


var myHasPosition = VRPositionState.hasPosition;


A Boolean.
