XRHand

The XRHand interface is pair iterator (an ordered map) with the key being the hand joints and the value being an XRJointSpace.

XRHand is returned by XRInputSource.hand.

Instance properties

size Read only

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()

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

forEach()

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

get()

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()

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

values()

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);
}
