XRJointSpace: jointName property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The read-only jointName property of the XRJointSpace interface contains the name of the joint it tracks.

Value

A string indicating the name of the joint. See the list of hand joints on the XRHand page.

Examples

Getting the `jointName`

Given a XRJointSpace, the jointName property will contain the hand joint name.

js

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

function renderFrame(session, frame) {
  // …

  for (const inputSource of session.inputSources) {
    if (inputSource.hand) {
      const indexFingerTipJoint = inputSource.hand.get("index-finger-tip"); // XRJointSpace
      indexFingerTipJoint.jointName; // "index-finger-tip"
    }
  }
}
