A UNIVERSAL DESIGN METHOD BASED ON MOTION ANALYSIS BY USING MOTION CAPTURE AND MUSCULOSKELETAL MODEL: CASE STUDY OF PRODUCT SHELF HEIGHT

Abstract

In recent years, many companies have focused on the concept of universal design (UD) to design products that can be easily used by users of diverse body characteristics in order to develop products that take user diversity into consideration. This study proposes the UD method that takes into account physical load in order to realize the design that is easy to use for as many people as possible, which is one of the concepts of UD. The actual motions during product use are measured by using motion capture, and the motions are applied to the musculoskeletal model for motion analysis to evaluate the load on the user’s body. This analysis results in deriving the user-friendly solution for each group and aggregating them to derive the UD solution that can be used by as many people as possible with a less physical load. The effectiveness of the proposed method is demonstrated by applying it to the design problem of a shelf height.
