ABSTRACT
Our goals in this chapter are to provide a brief introduction to human factors and to the Center for Research and Education on Aging and Technology Enhancement (CREATE) approach for ensuring adequate person-environment fit, as well as to provide an overview of normative changes in perception, cognition, and psychomotor functioning with age that should influence product design considerations. We look at some example products and outline how modeling can provide a useful alternative to traditional usability testing when trying to decide on the relative merits of alternative designs.
