Design for Human Variability (DfHV) is the practice of designing artifacts, tasks, and environments that are robust to the variability in their users. Designs often incorporate adjustability and/or offer several sizes to account for the different requirements of the target user population. There are several situations where DfHV can provide platforming opportunities that might otherwise be overlooked. This chapter provides a brief introduction to DfHV, outlines some basic techniques, and provides a description of scenarios where platforming and modularity might be a good approach.
