[nfbcs] New Braille Displays

[majolls at cox.net]

I recently posted a reply about the "new keyboard" on touch devices that "pops up".  This was in an email that was talking about the technology's application to tablets to provide dynamic buttons that popup on the tablet surface to provide a dynamic keyboard, and was showcased at CSum.  I made the comments that this technology developed by Tactus might be used to develop a more cost effective refreshable Braille display.  I didn't hear any response to my post.  I was wondering if any of you had heard similar rumors about developing Braille displays with deformable elastic polymers?  I've heard  this could drop the price of a braille cell from $80 (currently using piezo-electric cells) to about $10 per cell.  That would be a tremendous cost savings if it can actually be done.  Im just wondering if I'm getting excited over nothing or if a more affordable unit with more usable cells could really be in the future?

Does anybody hear anything from reputable sources that they'd like to share?

Thanks
