I am a Human–Computer Interaction Researcher and Augmented & Mixed Reality Developer. Currently, I am the Mixed Reality Tech Lead for the Raumtänzer GmbH. Previously, I was a Postdoctoral Researcher at the Niederrhein University of Applied Sciences, a Research and Development Engineer at the SMS group GmbH and a Research Associate at the University of Applied Sciences Emden/Leer. I studied Cognitive Informatics (B.Sc.), Intelligent Systems (M.Sc.) and Computer Science (Ph.D.) at Bielefeld University.My interests are Mixed Reality approaches for prototyping, training and assistance in work environments and educational settings. In my Ph.D. thesis, I was especially interested in the development and design space of Augmented Reality authoring tools, enabling (non-programmer) domain experts with varying levels of media competency to develop their own Augmented Reality Apps.As I am an open science and open-source advocate, I am trying to share as much as possible of my work as open source on GitHub (See: https://github.com/jblattgerste) and through scientific open-access publications (See: https://www.researchgate.net/profile/Jonas-Blattgerste).
