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

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.
