BrailleRing: The Braille Revolution

Tetragon is developing an innovative refreshable Braille display that will be small and, nevertheless, be capable of showing long lines of text. This is achieved by a ground-breaking technology which presents the Braille characters on the inside of a rotating ring.

Once again we were invited to present at this year's Zero Project Conference and we were also invited to join a small group of startups that work on Assistive Technology. To present our current challenges and future plans at the conference, we produced a new video that can now also be viewed on our website and on YouTube.

Today's FFG Spin-off Demo Day marked the official end of the Spin-off Fellowship, the funding program that supported our development in the last two years. Participants of the program presented their final results as well as their further plans and the event was accompanied by panel discussions. The whole online event was recorded by "der brutkasten" and can be viewed on YouTube.

The EXPO office of the Austrian Federal Economic Chamber (Wirtschaftskammer Österreich) asked us to borrow prototypes for an exhibition. These prototypes (not the newest ones) will be on display together with other innovative projects in a display cabinet at the Ars Eletronica Center in Linz for a period of two months. The goal is to raise awareness for iLab, an exhibition area at the upcoming EXPO in Dubai.

Due to the Corona crisis—and therefore limited access to buildings of TU Wien (Vienna University of Technology) and long delivery times—our prototype development is currently massively slowed down. However, our current sponsor, FFG (Austrian Research Promotion Agency), has granted a further extension of the funding period until the end of July to compensate for some of these inconveniences.

For the last three days we exhibited our work at the Zero Project Conference at the Vienna International Centre. We met several experts who gave us useful input on upcoming challenges and the market for Braille technology.

Today we participated at the START:IP Matching Day, which was initiated by INiTS, one of Europe's top business incubators. Our main goal was to find partners with experience in the business field of niche markets. We gathered some interesting contacts and will have further meetings with three companies.
