The Data Analysis on the Variation of Human Body in Movement

Based on the data collected by 3D body scanner, the research on body surface variations were conducted. The shoulders, the elbows, the waist-to-hip area, and knees were selected as key objects of the study. The appropriate actions and the movement scope were determined according to the dynamic features of different parts. The dynamic changes of body surface were investigated by regress analysis, and the significance and goodness of fit were tested to obtain the meaningful regression equations. Taking the lateral raise of back as case study, the paper revealed the methods of data analysis on the variation of human body in movement.
