As anyone knows those high-tech canes which tell you what is ahead or above
you cost too much for poor people to afford. So did the Optacon in its
glory days. I wanted one badly, but in the 1970's, VR in Illinois forbade
blind people from using it. It made me very unhappy, because I wanted to
learn how to read very much. I just couldn't do it until 1994.
