[citation][nom]zmbcat[/nom]As blind peoples senses sharpen, maybe they could get used to sensing just the heat of braille. One way or another, i sure hope this thing gets into production lines.[/citation]
I wish that were true. It's just a matter of receptor density in the skin, something akin to the pixels on a display. If the display has a low native resolution, everything will show up in low res, regardless of the quality of the signal. It's just how our skins are made.
Sense sharpening is a matter of training an receptor to pick up signals to it's maximum capacity, not beyond. People that can see so not use their skin for Braille, they just dont use the maximum ability of their sense organ, in that case the skin.
When there is a "hardware" limitation, there is nothing one can do about it. Sorry.
However, if this idea picks up with Braille electronic displays that use raised dots, it will be a winner for sure.
