Yes. Freedom Scientific quotes prices from $2,000 to $10,000. So
it might have to be an extra cost option. On the other hand...
NIST has developed a unique refreshable Braille technology that
can reduce cost by a factor of 10 or more. It will make possible
high performance Braille displays for $1000 or less, and enable
high speed reading devices about the size of a portable CD
player. While existing displays put Braille on a linear array of
dots, this design puts the Braille on the rim of a rotating
wheel, which moves the text past the user's fingers. Users can
adjust wheel speed, or can pause the wheel for stationary
reading. Tests thus far indicate a high degree of readability.
With advice from many Braille users and accessibility
organizations, a working second-generation prototype was first
shown at the Electronic Book 2000 conference in September, 2000,
hosted by Victor McCrary.
