 note = {The shoulder angle and elbow angle that are displaced during planing work, and the movement 
distance and the speed of hand plane were investigated, and verified the movements of the high-precision 
and low-precision university students. The students planed the Japanese cypress square lumber and 
photographed the work with two CCD cameras. The angle and distance of each part of the body were 
analyzed by motion capture using 3D coordinate measurement software.
As a result, in the upper group with high processing accuracy, the opening angle of the left elbow and 
the right elbow was smaller than that in the lower group, and a significant difference was observed. And 
the opening angle of the left shoulder of the upper group showed a larger value than that of the lower 
group, and a significant difference was observed. Regarding the movement distance of the hand plane, 
the upper group showed a larger value than the lower group, and a significant difference was shown in 
the comparison of the maximum value of the movement distance. The movement speed of the hand plane 
in the upper group was about 1.7 times faster than that in the lower group, and a significant difference 
was observed.},
