This study examined the use and need for assistive devices by 30 noninstitutionalized older visually impaired persons during intensive interviews in the subjects’ homes. It found a high rate of use of these devices, as well as the subjects’ expressed need for additional devices that they did not own. In addition, some of the subjects’ suggestions for the development of new devices indicated that the subjects did not have the latest information on assistive technology.
