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 stageParameters
read-only property of the VRDisplay

object containing room-scale parameters, if the VRDisplay
is capable of supporting room-scale experiences.
Syntax
var myStageParameters = vrDisplayInstance.stageParameters;
Value
VRStageParameters
object containing the VRDisplay
's room-scale parameters, or null
if the VRDisplay
is not capable of supporting room-scale experiences.
Examples
var info = document.querySelector('p'); var vrDisplay; navigator.getVRDisplays().then(function(displays) { vrDisplay = displays[0]; var stageParams = vrDisplay.stageParameters; // stageParams is a VRStageParameters object if(stageParams === null) { info.textContent = 'Your VR Hardware does not support room-scale experiences.' } else { info.innerHTML = '<strong>Display stage parameters</strong>' + '<br>Sitting to standing transform: ' + stageParams.sittingToStandingTransform + '<br>Play area width (m): ' + stageParams.sizeX + '<br>Play area depth (m): ' + stageParams.sizeY } });
