Computer Input Devices and the Elderly: A Musculoskeletal Disorder Focus

The aging process carries important implications for the design of human-computer interfaces. Decreases in vision, motor control and muscle force combined with a higher vulnerability to musculoskeletal disorders and to degenerative diseases should be taken in consideration when designing and selecting computer input devices for the elderly. This study reviews the recent research literature on computer input devices and their adequacy to the elderly user. Significant findings from evaluative studies are summarized, and recommendations are provided.
