Network-based accessibility services for people with disabilities

Most assistive technologies (AT) are based on hardware and/or software installed and used by individuals. For example, a screen reader is installed on a single computer so that a single user can hear spoken output of the information on the display. However, it is possible to share such technologies among several users over a network of one kind or another. A network-based screen reader, for example, would enable everyone in an organization (both with and without disabilities) to have access to the necessary text-to-speech and navigational capabilities on every computer, and to use them seamlessly with personalized settings. Network-based technologies can take advantage of certain economies and flexibility typically associated with thin-client environments. This article will describe such a system, now undergoing late-stage development.
