Q: I know there is a large key keyboard for people with sight disability. What else is there for other disabilities?
A: There is a ton of stuff out there - DragonSpeak (voice recognition) comes to mind as well as the Accessibility options built right into Windows XP like the magnifier and narrator. Without knowing more about the disability, I can't be more specific but here is a site with a lot of information (Section 508 is a set of government guidelines for accessibility): http://www.section508.gov/index.cfm?FuseAction=Content&ID=58
