In September 2017 the 1st Braunschweiger HoloHack took place at the Technical University of Braunschweig. Student teams from all over Germany competed against each other and developed mixed reality applications for the city of the future and the production of the future in 24 hours. The importance of visualization, communication and collaboration in these areas was obvious.
The five applications developed represent innovative solutions that can be applied in the context of urban factories. The connection between factory and city was particularly sought in two applications: Q. BE allows to close building gaps and derelict areas in cities with holographic ideas and suggestions in a playful way. In EmVis it is possible to walk through a digital, scaled-down model of a city and move through inter-atkive representations of different data such as noise maps.
