Abstract

Anderson and Rogers [1] have described a set of modifications which convert a standard model 33 tele-type into a device which produces embossed braille characters. Thus, blind computer users can communicate with a computer without the help of a sighted person to read the output. The disadvantage of this terminal alone is that either the applications program or the operating system of the host computer must have special software to map each output character into a sequence of three characters necessary to emboss its braille equivalent. Such software modification can be expensive and has to be done for each applications program or operating system the blind person wants to use.
