  let source = event.inputSource;
  if (source.handedness == user.handedness) {
    if (source.targetRayMode == "tracked-pointer") {
      let targetRayPose = event.frame.getPose(source.targetRaySpace, myRefSpace);
      if (targetRayPose) {
        myHandleSelectWithRay(targetRayPose);
      }
    }
