Examples

Using getJointPose()

Call getJointPose() with an XRJointSpace and an XRReferenceSpace to get an XRJointPose object.

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");
        frame.getJointPose(indexFingerTipJoint, referenceSpace); // XRJointPose
      }
   }
}
