Finger markersets include extra markers on the fingers, and the finger tracking is done by analyzing the kinematics of the hand and estimating the pose of each finger. The WristIn marker is removed and replaced by a forearm marker. Attaching finger markers uses mocap Velcro gloves and hand markers, which can be found from our webstore.

LFArm RFArm
Forearm
Place the marker on the front side of the forearm while in T-pose. For best results, slightly offset the left and right forearm markers to introduce the asymmetry on each side.
LFArm RFArm
Forearm
Place the marker on the backside of the forearm along the ulna between the wrist and the elbow.
LWristOut RWristOut
Fore Arm / Hand
Place the marker on the outside (lateral side) of the wrist axis. (distal end of the radius bone). Note that the wrist axis is not always located on the protruding bone but 1-2 cm more towards the hand.
LWristIn RWristIn
Fore Arm / Hand
Place the marker on the inner prominence (medial side) of the wrist axis (distal end of the ulnar bone).
LHandOut RHandOut
Hand
Place the marker slightly below the pinky knuckle. More specifically, between distal end of the fifth and fourth metacarpal bones.
LHandIn RHandIn
Hand
Place the marker slightly below the forefinger knuckle. More specifically, between distal end of the second metacarpal bones.
Fingers
Place a marker on the tips of each finger and the thumb.
This page briefly goes over the active finger marker set and how it needs to be set up.
The active finger Marker Set utilizes the tracking capability of active markers and its active labeling features to accomplish tracking of both the hands and the fingers. These Marker Sets require the active marker tracking solution and the Tag(s). Wired from an active Tag, each active marker must attach to the expected locations. For each hand, 10 active markers are needed for each hand.
Manus VR Gloves
Alternatively, you can also use Manus VR Gloves for tracking the fingers. For more information, refer to the Manus Glove Setup page.
The Active Base Station
Active Tag(s) with active markers.
A way to attach active markers onto the hands (e.g. gloves).
Baseline + Active Fingers (57)
Core + Active Fingers (62)
Right Hand + Active Fingers (10)
Left Hand + Active Fingers (10)
Total 10 markers will be attached on each hand (8 Active markers and 2 passive)
The 8 Active markers will be placed on the hand and the 2 passive markers will be on either side of the wrist.
Tags: Attach Tags to each hand for the active LEDs.
Active Markers (10): Each Tag connects up to 8 active markers. Position the wired active markers at the tip of all five fingers (5), one each on the knuckle of the index finger and the pinky finger (2), and lastly, place the remaining active marker on the inside of the bottom thumb joint.
Steps for creating an active finger Marker Set is the same as the other skeleton Marker Set:
Open the Builder pane and select the desired hand Marker Set under the drop-down menu.
Make sure all of the markers are placed in the correct positions. For the Core + Active Fingers (62) Marker Set, please make sure the passive full body tracking markers are also placed on the person's body.
Once the markers have been placed, ask the subject to strike the calibration pose.
Select the finger markers in the 3D viewport.
The Marker Detected must match Marker Required in the Builder pane.
Click Create.
