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.
