Examples

Using `XRJointSpace` objects

You can use an XRJointSpace object and an XRReferenceSpace to get an XRJointPose by calling XRFrame.getJointPose().

navigator.xr.requestSession({optionalFeatures: ["hand-tracking"]}).then(
  // ...
);

function renderFrame(session, frame) {
   // ...

   for (inputSource of session.inputSources) {
      if (inputSource.hand) {
        let indexFingerTipJoint = inputSource.hand.get("index-finger-tip"); // XRJointSpace
        indexFingerTipJoint.jointName; // "index-finger-tip"
        frame.getJointPose(indexFingerTipJoint, referenceSpace); // XRJointPose
      }
   }
}
