ABSTRACT
Healthcare is an important individual, societal, and economic issue and is receiving much attention with the aging of the population. Healthcare situations are often fraught with stress as individuals may be receiving information about diagnoses or treatment options, or engaged in treatment protocols. The use of technology and devices within the healthcare domain typically necessitates the need for just-in-time learning. Patient stress is an even more important concern with respect to healthcare technology because of the likelihood that the technology is being introduced to deal with a new and potentially troubling diagnosed condition, such as diabetes. Another important design consideration within the healthcare domain is in defining the “user group". Older adults in the United States use a wide range of technologies in the context of healthcare. One important function of a healthcare device is to provide users with information about their health status, such as body temperature, blood glucose levels, or blood pressure.
