[Blindmath] Tactile Displays?

[Theodor Loots]

Hi R!

The only similar commercially available tactile device I have found is the
GFW display developed by HandyTech, but costs far more than an arm and a
leg.  The "dots" on this device are spaced 3mm apart from one another.  It
also has a tool that connects with Maple so that you can view graphs and
diagrams, however, I doubt this would be useful when dealing with a lot of
detail.  In this case something like the TIGER is "cheaper" and much more
sufficient.  But, we're moving in the right direction I guess.

Kind regards,
t

Hi all,

The recent discussion on the list regarding the accessibility of Mathematica
reminded me of the time when I was personally researching the accessibility
of same software. I came across an article about a blind physicist. I
realise that there are quite afew around these days, but this particular
physicist caught my attention. The article mentions a device used by him
that consists of a camera attached to a tactile display with vibrating pins.
My questions is: how does this device operates? Also, is this product in the
market or just a personal invention?
The article can be found here.
