XRHand is returned byXRInputSource.hand.

Instance properties

sizeRead onlyExperimental

Returns25, the size of the pair iterator.

Instance methods

TheXRHand object is a pair iterator. It can directly be used in afor...of structure.for (const joint of myHand) is equivalent tofor (const joint of myHand.entries()).However, it's not a map-like object, so you don't have theclear(),delete(),has(), andset() methods.

entries()Experimental

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

forEach()Experimental

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

get()Experimental

Returns aXRJointSpace for a given hand joint orundefined if no such hand joint key is in the map.SeeMap.prototype.get() for more details.

keys()Experimental

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

values()Experimental

Returns an iterator with all theXRJointSpace values.SeeMap.prototype.values() for more details.

Hand joints

TheXRHand object contains the following hand joints:

Examples

UsingXRHand 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);}
