Evaluating Fit by Using Animated Body Scan Avatars and Digital Coveralls

Abstract

Digital garment simulations can be very useful for technical design teams when evaluating the fit of the functional or protective garments, especially when 3D body scanning technology is unable to fully capture certain poses. In this study, we tested a method of creating animated coverall simulations and using the obj files of three poses, i.e., A-pose, reaching front, and stepping front, for objective and subjective fit analyses. We used 29 body scans that were rigged in Mixamo to analyze ease amounts of digitally stitched coveralls in each pose. Pattern outlines were visible in the digital coveralls Circumferences, cross sections, volumes, as well as crotch heights, were measured from the obj files of the clothed and minimally clothed digital bodies. Results showed that our method was effective in creating realistic wrinkles/folds that indicate tightness. There were significant differences in the overall ease across the three poses. A-pose yielded the highest overall ease followed by reaching front and stepping front. Crotch ease was significantly the lowest in the stepping front pose. Animations were found to be signaling additional fit clues.
