Consider a large tabletop brailleboard-- it's too expensive to make all those pins in hardware, so how about virtual-ware? Is the technology for finger pressure pads sophisticated & small enough to produce a braille image on a fingertip? What about tracking a fingertip-- can we monitor the position of a fingertip (perhaps on a special table, but still cheap) on a table with enough precision to give the illusion that the braille is actually on the table surface? Is this already being investigated, and by whom? Considering that very little money is available for the handicapped (compared to defense or industrial applications), this system would need to be produced inexpensively. The brailleboard is good for scanning a page (or more?) of text-- something voice readers are lousy at summarizing. Even so, it'd be great to be able to skim, point and have the computer start talking; for example, some voice readers read the entire mail/news header before they get to the body. (e.g. date colon F R I comma fourteen december ninety fourteen colon fourty-eight colon twenty three dash zero eight zero zero from colon swanny open paren dave swan close paren-- we're not even through half a mail header yet...and imagine this with NO inflections.) Clearly a brailleboard would be really useful to skim/skip past the junk headers. This is just one useful application. Thanks, George Forman
