Aging Algorithm for Anthropometric Digital Humans: Quantitative Estimation for Ergonomic Applications

This paper introduces an approach to estimate the effect of aging on surface anthropometry, articulation limits and physical strength for digital humans at joint level. By making use of an anthropometric database, physical characteristic database and prioritized Inverse Kinematics architecture, the developed simulation system could be a core engine for ergonomic analysis at the conceptual design stage of a product development cycle. The proposed system could be an efficient tool for helping designers more quickly and easily identify ergonomic flaws. The results have been validated with real human subjects indicating the practical implication of the total system as an ergonomic design tool. .
