[Tactile-Talk] Other tactile displays

I don’t like the name either. Years ago, I spoke with the developer who is in Germany. At that time, the product was available in the U.S. Since then, I have gotten to know an optacon user in Switzerland who was interested in the product. He got a government grant to obtain the latest version of the product and has made some videos. I asked him of the user could update the product if there was new software. He said the developer was concerned about patent infringement so the user can’t update the product. I think this is unfortunate. I doubt this product will go very far.

Yes that is the one I was trying to think of.  I have always hated the nem of it.

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
