Try this out---alternative text entry system
I just read about this free software on the qiat listserve and thought I would give it a try. Dasher is a free software that allows for text entry by using one continuous motion of the mouse. Think of it as driving through a dictionary. By "steering" the mouse you can zoom in on a word or letter. It's tricky, but I can see the potential for people who can't manipulate a keyboard. It is even available for eye gaze users. See what you think. Enjoy the "gaming" experience.
