Modern graphical user interfaces (GUIs) have made
computers accessible to millions of people, but they have had the
unfortunate side effect of preventing some people from using
computers at all. A slight hand tremor can be enough to stop
someone positioning a mouse with accuracy and then making a click,
while a person with one useable hand can find reaching across a
keyboard a tiring and offputting chore - and that's before they
have to hold down the shift or control keys. For people with very
limited movement, the modern GUI is an impossible barrier. Skipper (screenshot
here) is a
new open source accessibility package which makes the best use of
whatever people with severe movement impairment can move. It
removes the barrier to GUI use for the disabled.
