In this study, we aim to develop individual sloper prototypes offering adaptive comfort to arbitrary parts of the body using personalized torso models created from symmetrized body scan data. This study is categorized by the following three features: (1) adaptive comfort that can be configured for any part of the body, (2) the use of personalized torso models, and (3) the use of two-dimensional triangular polygons rather than one-dimensional measurements. Triangular polygons encompassing the shape of the torso were used to create prototypes. The amount of space was determined by shifting the reference line and reference points on the reference line away from the torso. Personalized prototypes were sewn from sheeting and evaluated with a trial fitting. Both the trial fitting and survey results yielded positive results, confirming the efficacy of the personalized prototypes.

To obtain natural standing shapes without shoulder joint abduction motion, upper body shapes in a natural standing posture were estimated from 3D standing posture of 3D shape data using the morphing method, and the accuracy of those estimates was verified. 3D upper body shape data from 71 female subjects were used. Average shapes of 3D standing posture shapes and measured natural standing posture shapes were generated, and changes between average shapes in both postures were calculated. Changes were added to 3D standing posture shapes of individuals to generate estimated natural standing posture shapes. To verify accuracy, dimensions, regression analysis of vertex coordinate values, the distance between overlapping 3D shapes and cross-sectional shapes were compared. Although the arms tend to be misaligned, this method of estimation reproduced the body shape in a natural standing position while retaining the characteristics of individual body types.
