Designing universal access: Web-applications for the elderly and disabled

Throughout a person’s life they are likely to experience some degree of impairment. What must be ensured is that these individuals can benefit from the opportunities afforded by technology in the same way as those who are able bodied. With the Internet becoming an increasingly popular medium for organizations to deliver information and services to the public many of these technological benefits are provided through web applications. However, due to possible visual, physical or cognitive impairments, older users and those with disabilities are more likely to experience difficulties. This paper addresses issues relating to usability of web applications for elderly and disabled users and investigates ways in which it can be improved, and whether doing so will affect usability for younger and more able users. Results from experiments undertaken indicated that it was possible to develop a web application for elderly and disabled users without degrading usability for other users.
