Articles about hand held a Braille ebook.  So far it seems the screen is set up for Braille cells - that means it will also be able to take graphics.
Would be nice if it has the possibility to for having the cells closer  - or letting the spaces between the cells also include dots for more dots resolution for  graphics.



Braille e-reader concept can't be far from reality
The technology's already here<http://www.engadget.com/2009/03/31/researchers-develop-braille-for-vibrating-touchscreen/>, we just need a venture capital firm and a determined entrepreneur to make it happen. A foursome of designers -- Seon-Keun Park, Byung-Min Woo, Sun-Hye Woo and Jin-Sun Park -- have banded together to create the above pictured concept, an e-reader for those with limited or no vision. Their Braille E-Book concept theoretically relies on electroactive polymers in order to change the surface's shape as pages are turned, and while we fully expect the battery life to suffer due to all the necessary commotion, it's definitely a start that needs to happen.


Vibrating touch screen puts Braille at the fingertips
TOUCH-SCREEN devices like the iPhone are great when you can see them, but not much good if you are blind. Now a new way of presenting Braille characters on a mobile device could be the first step towards a Braille-ready touch-screen phone.
In Braille, letters are encoded using a two-by-three matrix in which each character is represented by a different configuration of raised and absent dots at the six locations. To display these dots on a touch-screen device, Jussi Rantala of the University of Tampere in Finland and colleagues used a Nokia 770 Internet Tablet, which has a piezoelectric material built into the touch screen that vibrates when an electric signal is applied to it. The team installed software that represents a raised dot as a single pulse of intense vibration, and an absent dot as a longer vibration made up of several weaker pulses (see diagram).
