Human factors and aging: an overview of research needs and application opportunities.

Diversity and a potential for growth characterize the field of human factors and aging. An overview of this area is presented to complement the in-depth articles that appear in this special issue. The historical origins of human factors and aging are presented, followed by a review and evaluation of the importance of conceptual thinking for this field of inquiry. The need to assemble basic data on the capabilities and limitations of the elderly, including subpopulations, is offered as a major and critical challenge. The areas of work, retirement, mobility, and the home environment serve to illustrate applications and avenues of intervention. Throughout the paper the status of current research and directions for future research are highlighted.
