Microcomputers could help reduce two of the principal fears of the elderly: inadequate income and loss of independence; yet there are indications that the elderly do not use computers very extensively because they see them as too complicated or because some of the physical impairments of advancing age make using standard systems too difficult for them. Previous research has shown a high degree of interest in computers among the aging, even in those over 85; however, the research has not focused on the elderly's special needs in the human-computer interface. Research is required on alternative input devices, such as the touchscreen and voice recognition, on menus and screen design, and on the use of color for coding or display background.
