Configuring products or environments for the size of their human users requires the consideration of several characteristics of the target user population, including body dimensions (anthropometry) and preferred interaction. Users are both adaptable and imperfect observers, which often makes it difficult for them to distinguish between candidate designs. This insensitivity is described by a concept called “just noticeable difference”, or JND. This paper presents an implementation of JND modelling and demonstrates how its use in the sizing of products or environments for target user populations can improve expected performance.

The use of humanoid glyphs in graphs for representing human variability in the spatial design of products

Garneau, C. and Parkinson, M. (2013) Proceedings of the 2nd International Digital Human Modeling Symposium.

From simple color-coding to more intricate forms like the “Chernoff face”, glyphs are a means of visualizing multidimensional data. The spatial design of products for their users presents a unique opportunity for using glyphs as a visual metaphor for encoding data, chiefly due to the multivariate nature of many commonly encountered problems.
