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.

The slides from our presentation at IKT-Forum are now available on the hosts website. We enhanced these image-heavy slides by adding comments, so even people who did not attend the conference can get a good impression of our current state of development.

We will give an update on our project on July 9th at the upcoming IKT-Forum in Linz, a conference for people with and without disabilities. Following our presentation, there will be an opportunity to see our current mockups. The conference will be held in German.

Today we had a first meeting with Resch GmbH, an Austrian company from Styria specialized on prototyping and production. It was a very pleasant meeting and Resch will immediately start to manufacture some parts for our next prototypes, hopefully marking the beginning of a long-time collaboration to make our BrailleRing reality.

We were invited to present our project at an event called Venturepreneurship Aula at the University of Graz. Today's Venturepreneurship Aula had a focus on social entrepeneurship. In a short pitch we asked for contacts to manufacturers as possible consulters for the prototyping and as future producers of our BrailleRing. A lot of people were willing to help and shared their contacts with us.

For the past three days we showed our mock-ups and our upscaled prototype to a broad audience at the Vienna Research Festival. The working prototype was refined for this event, so we were able to show it in action for all three days. Children loved to type in their names on our laptop and then watch our BrailleRing forming the letters in Braille.

Today, the Vienna Business Agency held an event about Social Tech, where we showed our prototypes to a small but curious audience. It was the second time we attended one of these so called "Business Treffs". The first one was in October 2017 and was directly aimed at technologies for blind people.

This week we attended the International Conference on Computers Helping People with Special Needs (ICCHP), presenting our paper "BrailleRing: The Shortest Long Braille-Display in the World – A Review of the State-Of-The-Art and a New Approach". Among other interesting people we also met Michael Curran, who started the popular screen reader NVDA. He would love to include support for our device in his software.
