Hi,
You might be interested in a device called the OPTACON: Optical to Tactile
Converter. I am totally blind and I use my OPTACON to read all kinds of
printed material. Unfortunately, for a variety of reasons, the OPTACON,
which was first manufactured in the early 1970's, is no longer produced. I
have a few used units available for sale. I acquired these a while ago to
use for spare parts but I could part with one or two and still be covered.
You, may contact me directly at [log in to unmask]

Bill
