Digital Human Modeling for Design and Evaluation of Human-Machine Systems

Digital Human Modeling is an emerging area that bridges computer-aided engineering design, human factors engineering and applied ergonomics. Especially for ergonomics questions, digital humans are already being used. The paper describes different fields for the application of digital human modeling in product design, assembly and manufacturing. Current research on digital human modeling in training, risk assessment of workplaces, hand-object interaction, modeling eye movement, and the assessment of comfort is highlighted. The case is made for a combination of anthropometric models and cognitive models. In addition, the consequences of a wider application of digital human modeling in product design, assembly and maintenance are discussed, especially with regard to the education of engineers and human factors specialists.
