ABSTRACT
Effective and safe use of biomedical products requires, among other capabilities, knowledge, interpretive reasoning, attention, and memory. Biomedical products are not alone in these requirements. The integration of information technology (IT) into communications, manufacturing, transportation, power, and medical systems has shifted the predominant activities of many human-performed tasks from manual to cognitive. However, biomedical products support health systems and their successful use is often critical. Designers need to understand and accommodate the knowledge and cognitive abilities of users in product design. As a result, data, models, and metrics for describing and understanding cognitive tasks

and the cognitive capabilities of persons performing them have become very important to engineering design.
