Abstract
Obesity is a growing issue in western societies with consequences for the field of human centered design. Most anthropometric data sources assume the data follow the Gaussian distribution, with population data symmetrically distributed above and below the mean value. This assumption is often true in length measurements like body heights, but may not be true for measurements more sensitive to body mass, like body weight, hip width, elbow-to-elbow width, and body depth. While length measurements have remained relatively stable over time in western societies, mass related measurements are increasing. The authors have experience in providing data via an interactive website DINED, which seeks to make anthropometry accessible without requiring expert knowledge about anatomy and statistics. Currently all DINED dimensions are assumed Gaussian, including those related to body mass. This might not work when designing for plus size people. Future additions in DINED will be about design for obesity and about how to implement 3D scanning into the design process in order to redress these defects.
