TeleSensory did a lot of research and testing before they chose the size of the Optacon display and the resolution (space between individual pins). Other fingers can be taught to read with the Optacon just as they can be taught to read braille. It does take training and practice, a sort of finger-education. Those who ever tried to read micro-braile know why it never caught on even though more content would have fit on pages. The resolution was just too close and the brain could not comprehend it. Those of us who had Cannon Optacons discovered that the smaller display provided less detail and images which were less clear and less able to be fine-tuned. There is a lot we don't know about brains and fingers, but we do know some and I think we should keep in mind what we painfully already learned. When I'm reading, I'm reading. Using other body parts besides my hands does not appeal to me personally.
