I design and produce 360° spatial visualizations from 2003 onwards for planetariums, VR and AR applications and interactive displays. Some recent productions are Superhelden der Ozeane (Superheroes of the Deep Sea), which uses many different media formats, including: fulldome, VR full spherical and stereographic content or the 360° film Dream to Fly, on which I consulted on and produced parts for, won the most prices in the fulldome industry. My productions have a global reach and have been awarded many industrial prizes.In my practical and research work I am interessted in visual concepts, which make the invisible visible and experiencable by using the spatial component. In my research I am compiling an extensive investigation of historical epistemic concepts in science communication. This maps the field of Geography and Cosmology used in spherical environments from the 17th century to contemporary times.These findings explore how thinking, understanding, and acting with spatial knowledge in 360° have shifted and is informed by excellent interviews with experts in the field and a strong practice based element which unifies and tests the outcome. I strongly believe that this research is valuable to every new 360 design work in Fulldome, VR, AR or MR.
