For the talking book reader that Thomas has here, a company called HumanWare, just outside of Montreal, sells these devices internationally for $350 to $400 a pop.
The KNFB Reader was around $100 the last time I checked. Some of the more sophisticated reading machines, closer to TV readers, where you place printed material underneath a camera that then blows it up, based on the person's ability to read or to see, are in the thousands of dollars. Braille display machines that Mr. Rae talked about, the refreshable Braille displays, are in excess of $3,500.
Prototypes are coming onto the market. CNIB participated in something called the Orbit Reader. It's just coming to fruition now, selling for $500, but it's still first generation. Just think back to microwaves; they were clunky, and they sort of worked.
It will get better. As these devices go through their life-cycle development, they will get better, and they will become cheaper and do more.
