the Glossary by Sun Microsystems defines accessibility as follows: The degree to which software can be used comfortably by a wide variety of people, including those who require assistive technologies like screen magnifiers or voice recognition. (Sun Microsystems, 2000, Sun Global Glossary Collection). Often the term is defined more narrowly to mean ease of use for the disabled or elderly people in particular. I'm myself sight impaired and have been using Windows since 95. Therefore we'll concentrate on screen readers in particular.
