I had the opportunity to learn how David used a BrailleNote which is made by Humanware. It is basically a computer with a braille display. The David's model had wi-fi to connect in the classroom and could print wirelessly. Some even have 3G cards for" always on" connectivity.
One thing that particularly interested me was how well suited a visually impaired person is to computer programming. A blind person has to be able to create order for everything in their mind. Which is the basics of programming.
Consider this. A blind person with one of these can communicate in very advanced ways, just like a sighted person can. And sometimes, we can communicate in ways we can hardly imagine.
