A Standing Function Evaluation System Based on Virtual Light Touch Contact and Factor Analysis.

This paper proposes a standing function evaluation system on the basis of factor analysis for indices related to standing characteristics. For this approach, five standing function factors were checked in a large-scale experiment using the results of extraction from 48 indices based on factor analysis. Five factors were extracted from these indices, and the related score radar charts indicated that most factors changed with age. The evaluation results suggest that the system facilitates intuitive comprehension of standing-related factors based on these charts.
