Braille for the World

TETRAGON develops innovative Braille products, in particular refreshable Braille displays. One of our priorities is to make these products available to as many people as possible. To achieve this goal, we are also working on a new co-creation and distribution concept with partner companies in Africa.


Today, some parts of our hardware prototypes were presented at a workshop in Kenya, and members of a local makerspace successfully assembled them as an early proof of concept for future partnerships. Tetragon participated online to provide information and guidance. We thank the people from FH Technikum Wien (Austria's University of Applied Sciences for Technology and Digitalization), who were physically present in Kenya, for including us in this workshop.

Out of 376 submitted projects, Tetragon was ranked first for Eureka's Innowwide funding. The funded project will run for 6 months, starting in May, and consists of a pilot of our co-creation concept with iZone Hub, a partner in Harare, Zimbabwe.

Today we participated in a co-creation workshop with experts and potential partners from Africa. The workshop was hosted by the Vienna Business Agency and resulted in a collection of topics and insights that could be important for bringing our technology to Africa.

In the context of the upcoming re:publica in Germany, a festival for the digital society, we present our concept of cooperation with companies in Africa to potential partners. For this purpose, we have also created a video presentation and two folders with recent photos of our Braille displays. You can find all this information on a new subpage:
