Computer systems have the potential to assist older adults by supporting independence, enhancing social communication, and enabling healthcare activities. Yet older adults' adoption rates continue to lag behind younger and middle-aged adults. We report data from 249 older adult computer users (65-93 years of age) that identify the details of their perceptions of computer usefulness for a range of everyday activities. Participants rated the importance of activities to their quality of life and the usefulness of current computer systems for supporting those activities. These experienced computer users indicated that computers were meeting their needs for some activities (e.g., social communication, games) but not for other activities (e.g., calendaring, healthcare, recreation and learning). Our data provide guidance for (a) introducing the potential of computer systems to current non-users and (b) designing systems targeted to meet the needs of older adults and enhancing computing functionality for them.
