Tetragon is an Austrian working group which started at TU Wien (Vienna University of Technology). Our mission is to improve the lives of people with visual impairments by developing innovative technology. From 2018 to 2020 the project was funded by an FFG program called Spin-off Fellowship, which sets the goal to found a spin-off company.
Wolfgang Zagler is a retired professor, who had his own working group for Assisting Technologies at TU Wien. He has decades of experience with Braille displays and was supervising two master theses in which the concept for our first product was developed. Even in his retirement he is eager to bring new assisting inventions to life.
Dominik Busse studied Mechanical Engineering, where he specialized in Lighweight Structures and Applied Machine Elements. He is engineering and building prototypes for Tetragon since his master thesis.
Michael Treml studied Media Informatics. He came up with the initial idea of combining grouped Braille dots in a rotating device and started his work on the general concept and the software behind it in his master thesis. From 2018 to 2020 he was leading the funded Spin-off Fellowship project.
Andreas Dünser studied Biomedical Engineering at FH Technikum Wien. He joined Tetragon in early 2018 to build prototypes and conduct user studies for his bachelor thesis. Currently he is studying for his master's degree in Innovation and Technology Management.
István Deák studied Mechanical Engineering and Management of Technology at the Universities of Technology in Vienna and Delft. He is already experienced as a founder and is now bringing his entrepeneurial knowledge to Tetragon.
Georg Ehrenfels learned the job of a watchmaker and is an expert in precision mechanics. He was part of Wolfgang Zagler's working group and is involved in the assembly of our mockups and prototypes since early stages.
Mike Busboom is an expert in Braille reading and Tetragon's most important connection to the blind community, because he is blind himself. He has more than 20 years of experience in Braille display marketing and was also consulting Wolfgang Zagler's working group.
