Active Finger Marker Set

This page briefly goes over the active finger marker set and how it needs to be set up.

Overview

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 page.

Requirements

  • The Active Base Station

  • Active Tag(s) with active markers.

Creating the hand

Steps for creating an active finger Marker Set is the same as the other skeleton Marker Set:

  1. Open the and select the desired hand Marker Set under the drop-down menu.

  2. 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.

  3. Once the markers have been placed, ask the subject to strike the .

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.
