Waist Markers

Note that the waist markers are the key markers in modeling the pelvis bone, which is the major segment governing the other subsequent Skeleton segments. For best results, avoid placing the waist markers in a rectangle shape. When tracking multiple actors with similar proportions, introduce an offset to one of the WaistBack marker, or the WaistCMarker (included only with the 13 additional Marker Set), to create an asymmetrical arrangements.

Label	Related Segment	Description
WaistLFront WaistRFront	Pelvis	Placed the marker on the protruding bone located on the front of the pelvis (left/right anterior iliac spine bone). The prominence can be palpated from left and right side of the waist.
WaistLBack WaistRBack	Pelvis	Place the WaistLBack and WaistRBack markers above left/right hip; about 10 cm above the hip joint.

Leg Markers

Label	Related Segment	Description
LThighFront RThighFront	Upper Leg	Place the marker on the front side of the thigh, along the midline. For best results, slightly offset the height of the left and right markers to introduce the asymmetry.
LKneeOut RKneeOut	Upper Leg	Place the marker on the outer prominence of the knee joint; on the lateral epicondyle of the femur. Palpate the knee for the protruding bone from the upper leg, and place it right on the axis. Ask the actor to flex and extend the knee few times to confirm that the markers are placed along the axis and maintain stationary throughout the range of motion cycles.
LShin RShin	Lower Leg	Place the marker on the shin bone; on the midline of the lower leg. For best results, slightly offset the height of the left and right markers to introduce the asymmetry.

Foot Markers

Label	Related Segment	Description
LAnkleOut RAnkleOut	Lower Leg/Foot	Place the marker on the protruding bone outside of the ankle joint; on the lateral end of the malleolus bone.
LToeOut RToeOut	Foot	Place the marker just before the little toe joint; on the distal end of the fifth metatarsal bone.
LToeIn RToeIn	Foot	Place the marker just before the big toe joint; on the distal end of the first metatarsal bone.

Hinged Toe Markers

Hinged toe Marker Sets create toe segments in the Skeleton. Two additional markers are added to each foot, one on the toe-tip and another on the heel. The hinged toe markers are included in all baseline Marker Sets except for Baseline (37) and Upper Body Marker Sets.

Label	Related Segment	Description
LHeel RHeel	Foot	Place at the center of the heel.
LToeTip RToeTip	Toe	Place the marker on the tip of the second toe; next to the big toe.
