Abstract
The purpose of this study is to clarify the motion characteristics of some transport (reach) movements by measurement of three-dimensional motions with V.T.R.
Experiment has been carried out by following procedure; (a) Six right-handed male students aged 21 to 23yr (mean 21.7yr) served as subjects, (b) Each motion picture from two direction (Frontal and Lateral planes) was recorded on V.T.R. and the three-dimensional coordinates of the marked points were read from the synthesized picture by Position Analyzer. And displacement, velocity, acceleration, joint angle and three-dimensional motion path were calculated.
The result can be summarized in the following points;
(1) The mean overall motion path length for all experimental condition is found to be about 115 % of the linear distance.
(2) The ratio of the movement along the height axis to the short linear distance is larger than that of the long linear distance.
(3) Upper extremity joint function used each motion are different by motion distance and direction.
