Potential Application of Temporal 3D (4D) Scanning to Ergonomic Design: State-of-the-art and its Perspectives

Abstract

Objective: This study aimed to provide a comprehensive review of literature on 3D and 4D scanning technologies and potential applications of 4D scanning techniques in ergonomic product design. Background: Dynamic anthropometric data is needed to consider the changes of human body dimensions while using a product in the product design process. Method: A literature review was conducted on 34 papers which were selected by the process of title screening, abstract screening, and full text screening. Results: 3D scanning techniques can be classified into three catalogs: laser, structured light, and stereo photogrammetry. Though still challenging, 4D scanning systems self-built or commercialized have been developed. 4D scanning systems have been applied to understanding foot-shape changes and foot kinematics during walking, analyzing human facial movements, and evaluating the fit of sportswear design. Conclusion: 4D scanning systems have great potential in design and evaluation of ergonomic products. Application: The literature survey results can be of help to understand 4D scanning systems and their applicability in ergonomic design and evaluation.
