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.
Michael Treml (Dipl.-Ing.)
Software Engineering
Michael Treml studied Media Informatics. He came up with the initial BrailleRing idea of combining grouped Braille dots in a rotating ring for his master thesis. Today he is working on his doctoral thesis in the field of technologically supported braille teaching.
