The Chinese abacus uses two upper beads to represent the 5s and 5 lower beads to represent the 1s, the 7 beads can represent a hexadecimal digit from
Hand-Over markers and high resolution cameras. However, if the cameras cannot see the markers then they are unable to measure them.

The traditional method of adding hand and finger motion is to key frame the fingers. This is a process similar to the old claymation process; move the finger, record the frame, move the finger again, record the frame. Key framing is easier using animation software where a beginning and an ending position can be set up, then the
