I actually trained on this device for a while when I was in the 6th and 7th grades. It was called the StereoToner (pronounced "stereo toner" though I'm not sure if I've got the spelling correct). It was pretty compact, much smaller to carry than an optacon. The cammera was cylintrical in shape with the aperature at the "bottom" end of the cylinter and the connecting cable coming out of the other end. A flat rotary knob controling the contrast was located at the "top" end of the cylinder and, I believe, there was another, slider type control along the side of the cylinder whose use I do not remember. I found it very possible to read using the tones and stereo representation of the characters.

An auditory Opticon! I'm sure I could never have mastered anything like that. But I have one friend who probably could--and not only that but he's one of the few people I know who lost all of his vision in infancy but can visualize very complex objects. I think a person would almost have to be audio-visually synesthetic to use such a device because even if you had perfect pitch, characters would probably almost always be slightly different so you couldn't just memorize a particular chord for each letter. This might give rise to a crazy new art form--drawing or writing something such that the result created an Opticon symphony! Kellie
