Instance properties

size Read only Experimental

Returns 25, the size of the pair iterator.

Instance methods

The XRHand object is a pair iterator. It can directly be used in a for...of structure. for (const joint of myHand) is equivalent to for (const joint of myHand.entries()). However, it's not a map-like object, so you don't have the clear(), delete(), has(), and set() methods.

entries() Experimental

Returns an iterator with the hand joints/XRJointSpace pairs for each element. See Map.prototype.entries() for more details.

forEach() Experimental

Runs a provided function once per each hand joint/XRJointSpace pair. See Map.prototype.forEach() for more details.

get() Experimental

Returns a XRJointSpace for a given hand joint or undefined if no such hand joint key is in the map. See Map.prototype.get() for more details.

keys() Experimental

Returns an iterator with all the hand joint keys. See Map.prototype.keys() for more details.

values() Experimental

Returns an iterator with all the XRJointSpace values. See Map.prototype.values() for more details.

Hand joints

The XRHand object contains the following hand joints:

Examples

Using XRHand objects

const wristJoint = inputSource.hand.get("wrist");
const indexFingerTipJoint = inputSource.hand.get("index-finger-tip");
for (const [joint, jointSpace] of inputSource.hand) {
  console.log(joint);
  console.log(jointSpace);
}
