范例

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
  }
