The linearVelocity read-only property of the VRPose interface returns the linear velocity of the VRDisplay at the current VRPose.timestamp, in meters per second.

In other words, the current velocity at which the sensor is moving along the x, y, and z axes.


var myLinearVelocity = VRPose.linearVelocity;


A Float32Array, or null if the VR sensor is not able to provide linear velocity data.
