Fields

Name	Value	Description
Palm	0	The center of the palm. Coincides with the grip position represented by this hand's SpatialInteractionSourceLocation, reoriented to align with the forward direction of the other joints.
Wrist	1	The center of the wrist.
ThumbMetacarpal	2	The joint in the base of the hand that poses the thumb's metacarpal bone.
ThumbProximal	3	The first knuckle that poses the thumb's proximal phalanx.
ThumbDistal	4	The second knuckle that poses the thumb's distal phalanx.
ThumbTip	5	The point on the surface of the thumb at the tip.
IndexMetacarpal	6	The joint in the base of the hand that poses the index finger's metacarpal bone.
IndexProximal	7	The first knuckle that poses the index finger's proximal phalanx.
IndexIntermediate	8	The second knuckle that poses the index finger's intermediate phalanx.
IndexDistal	9	The third knuckle that poses the index finger's distal phalanx.
IndexTip	10	The point on the surface of the index finger at the tip.
MiddleMetacarpal	11	The joint in the base of the hand that poses the middle finger's metacarpal bone.
MiddleProximal	12	The first knuckle that poses the middle finger's proximal phalanx.
MiddleIntermediate	13	The second knuckle that poses the middle finger's intermediate phalanx.
MiddleDistal	14	The third knuckle that poses the middle finger's distal phalanx.
MiddleTip	15	The point on the surface of the middle finger at the tip.
RingMetacarpal	16	The joint in the base of hand that poses the ring finger's metacarpal bone.
RingProximal	17	The first knuckle that poses the ring finger's proximal phalanx.
RingIntermediate	18	The second knuckle that poses the ring finger's intermediate phalanx.
RingDistal	19	The third knuckle that poses the ring finger's distal phalanx.
RingTip	20	The point on the surface of the ring finger at the tip.
LittleMetacarpal	21	The joint in the base of hand that poses the little finger's (pinky's) metacarpal bone.
LittleProximal	22	The first knuckle that poses the little finger's (pinky's) proximal phalanx.
LittleIntermediate	23	The second knuckle that poses the little finger's (pinky's) intermediate phalanx.

Remarks

All joints except for tip joints are interior to the hand. Finger joint poses represent the base of the named bone. Joints are oriented with forward (-z) pointing towards the tip of each finger, up (+y) pointing out of the back of the hand or finger, and right (+x) pointing perpendicular to forward and up.
