[Tactile-Talk] Other tactile displays

[Keith Shaw]

There is an "optacon alternative" from a German developer called the
videoTIM, with a website here:
http://abtim.de/home__e_/the_videotim/the_videotim.html

It works with a hand-held camera and has an array of 16x16 pins with a
uniform spacing of 2.5mm. The display is based upon piezo actuators  which
allows fast refreshing - 24 frames (all 256 pins) per second.

It is built to order, similar to the situation with the Graphiti, and was
priced at 9,500EU when introduced in 2020. However, I'm not aware of anyone
in the US having experience with this particular display.

If there is real interest, I could go back into a database that has an
accumulated 100+ worldwide projects tackling the deceptively difficult
challenge of developing a low cost alternative to the ubiquitous piezo
bimorph actuator.

Best,
Keith
