ABSTRACT
Hand capture is very difficult and at the same time very valuable. Emotions can be conveyed with subtle movements of hands and fingers. When dealing with motion capture, however, fingers give very small areas to place markers on, which create some interesting issues and challenges. There are several ways to rig a hand for motion capture. Each rigging method calls for a certain number and configuration of markers. All the marker sets for the hand are relatively simple and there are a couple of important criteria that apply to all the hand marker sets. The first one is that all the markers should be placed on the backside of the hand, not on the palm side. Markers are more visible to cameras on the back side. The second one is that markers placed on a finger should be as centered as possible on the finger. The rig needs a chain of joints to control the finger motion.
