A burgeoning area of investigation in the wake of advances in in-home technology has been the application of those new technologies to enhance the health and independence of older adults without the constraints and expenses of the traditional health care system. Increasingly, researchers are using home monitoring and assistive technologies to identify changes in health and behavior in home settings, and to facilitate successful adaptation to those changes. The successful application of assistive and monitoring technologies depends on receptivity of potential users, i.e. the older adults, family members, health care providers and others. In this chapter, we will review the current state of research in older adults' perceptions, attitudes, and priorities regarding in-home technology designed for health monitoring and/or maintenance of independence. Further, we will summarize current thoughts regarding ethical issues in the application of these technologies to older adults as end users.
