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 orientation read-only property of the VRPositionState interface returns the orientation of the sensor at the current VRPose.timestamp, as a quarternion value.
The orientation yaw (rotation around the y axis) is relative to the initial yaw of the sensor when it was first read or the yaw of the sensor at the point that VRDisplay.resetPose() was last called.
Syntax
var myOrientation = VRPose.orientation;
Value
A Float32Array, or null if the VR sensor is not able to provide orientation data.
Examples
TBD.
Note: An orientation of { x: 0, y: 0, z: 0, w: 1 } is considered to be "forward".
