Hi all.

The most sophisticated talking tactile system is as provided by the Royal
National College for the Blind of Hereford UK.

The T3 system gives infinite reproduction of all forms of visual image using
Zychem swell paper, in this format colour can be added for the VI and unlike
Tiger embossers the line width and texture infills are of a very wide variety
of options.

T3 is already being used at University level in Biology and Neuroscience

The RNC has a department dedicated to talking tactiles, contact Elaine
Edwards on +44 [0] 1432 265725 or email ee@xxxxxxxxxx

More information can be seen at www.rncb.ac.uk/t3

Hi John,

Thank you for your email.
We're currently trying to get samples of brain images to tiger embosser
manufacturers to assess how much detail I can get from them, but this
technology looks really promising.  With regard to the IVEO technology,
we're not really sure how useful this might be, as I'm trying to find ways
to access neuroimaging as independently as possible, and my understanding
of the IVEO touchpad is that I'd require sighted assistance to assign
labels and descriptions to an image.  The VOICE software also sounds very
interesting, and we'll definitely try this too, but I was just wondering
how easy it might be to build up a mental image spatially.  With a line
graph for example, is it possible to quantify or work out the scale, e.g.
from the no. of seconds the tone sounds for.   We've also come across the
Audiographing calculator-do you think this might be more useful to us?
Also, do you happen to know how far research has managed to get in terms
of producing tactile diagrams in real-time?

Many thanks
