VIDasher is a free communication system for low-vision or blind people
who cannot use a regular keyboard. For example, blind people who have
VIDasher plays a word-game known as `Convergence'. It guesses what
word you are thinking of, and you respond `earlier' or `later' if your
word is alphabetically before or after the guess, respectively. Your
responses are conveyed through two switches. (A one-switch version
could also be made.)
VIDasher can be personalized to make it efficient for writing in your
own preferred vocabulary.
The main version of VIDasher is a four-action version intended to be
used with short and long presses of two switches.
