Looks like a decent list to me and remember folks, were it possible/practical (economical)to build a device with all the transparency of the true optacon, newer technology should indeed allow the results to be available in a final device which should be very much smaller and lighter. We now have mysterious chips capable of managing tasks such as audio amplification once requiring entire circuit boards--and way , way back, things called tubes. I remember my upgrade board for the total talk PC in 1986 to give me 640K of memory--on reflection, the size and intricacy of the thing was truly frightening. Now we're talking 4 GB contained in a device smaller than my pinkie finger--and affordable too. Fact is, I imagine, if the old platform is entirely discarded, a totally portable device, possibly with the tactile array and camera in one unit, perhaps sliding over the reading finger like a ring with the processing unit, if necessarily separate, strapping onto the wrist like a watch. Remember James Bond with the shoe phone? Doug: available in pocket-sized versions too! Hi Jerry, good point. Way back when Jim Bliss was president of TSI, I posed that question, this was when the original lens were still glass; I dropped the camera a few times & required a lens replacement, costing $500 each time. Fortunately, they soon began producing plastic lenses. The answer to my question of course, was that wireless cameras would add greatly to the already exorbitant Optacon cost.
