Considering Secular and Demographic Trends in Designing Long Lifetime Products for Target User Populations

In Publications

de Vries, C., Garneau, C. J., Nadadur, N., and Parkinson, M. (2011). ASME Journal of Mechanical Design 133(8).

The objective of this study is to investigate the effects of design decisions on the accommodation afforded by long lifetime products over extended periods of time, and to then make recommendations to improve accommodation. Phenomena such as rising obesity rates, aging, and changes in user demography can affect the spatial and the physical requirements of the user population. As a result, products with long lifetimes must be robust to these secular and demographic trends. Continue reading…

Preliminary validation of a tool for visualizing anthropometric data

In Publications

Garneau, C. J. and Parkinson, M. B. (2011). Proceedings of the First International Symposium on Digital Human Modeling.

Accurate representations of anthropometry are necessary for effective digital human models. It has been known for decades that inappropriate application of univariate anthropometric data to multivariate problems yields suboptimal design performance. However, traditional design tools including textbooks and univariate data tables do not foster an understanding about appropriate means for solving multivariate problems. Continue reading…

Probability of user fit for spatially optimized products

In Publications

Garneau, C. J. and Parkinson, M. B. (2011). Proceedings of the 2011 ASME International Design Engineering Technical Conferences and Computers and Information in Engineering Conference. Washington, DC.

This study offers a new method for understanding the likelihood of acceptable fit for users of adjustable products and environments and is a useful tool for aiding the designer in making decisions about problems involving human variability. Continue reading…

Simultaneous consideration of user acceptability and regulatory compliance in vehicle seat design

In Publications

Parkinson, M.B. and Garneau, C.J. (2011). International Journal of Vehicle Design 55(2): 162-173.

The success of a vehicle seat is defined in large part by its acceptability to users and compliance with applicable regulations. Simultaneously satisfying both of these objectives can be challenging, and it is the goal of the designer to balance the requirements of each to optimize the design. Continue reading…

A comparison of methodologies for designing for human variability

In Publications

Garneau, C.J. and Parkinson, M.B. (2011). Journal of Engineering Design 22(7): 505-521.

In the design of artifacts that interact with people, the spatial dimensions of the user population are often used to size and engineer the artifact. The variability in anthropometry indicates the fixed allocation of space, adjustability requirements, or how many sizes are needed to accommodate the intended user population. Various tools are used to achieve this goal, including boundary manikins, digital human models, prototypes and population models, and hybrid methods that combine the approaches. The present work explores each of these and their relative strengths and weaknesses. Continue reading…
