A recent research article summarizing a study designed to update the anthropometry data for US based truck drivers reveals some interesting statistics about truck driver size and safety, and also brings to light the fact that ergonomists and designers often don't have accurate data, even if such data is critical to a design outcome. In this article Peter Budnick reviews the study and also shares some thoughts on the importance of human-centered design, up-to-date anthropometry data, as well as new developments in the way it is used to create more accommodating designs.
