About me

From late 1999 until early 2006, I studied Computervisualistics at the University of Magdeburg, with a minor in psychology and educational science. My studies focused on usability and human computer interaction; other areas of interest included visualisation & graphics, databases, project management and creativity. I wrote my project thesis about interaction in augmented reality at the Human Interface Technology Lab New Zealand and his Diplom thesis about emotions in the human-computer-interaction at the Fraunhofer-Institute for Graphics Research in Rostock. I received my Diplom degree in Computervisualistics in early 2006. After graduation I worked in the Requirements and Usability Department of the Fraunhofer Institute for Experimental Requirements Engineering as usability engineer and consultant for almost 2 years. My main project was about how to design joy-of-use into the human-computer interaction. Before joining CoSy, Christian was a member of the "International Graduate Research Group for Cross-Modal Interactions in Natural and Artificial Cognitive Systems" at the University of Hamburg from 2008 for two years.


01/2002 – 09/2005 Stipendiat der Friedrich-Ebert-Stiftung
2008 Reisekostenstipendium der Gesellschaft für Kognitionswissenschaft
01/2008 – 12/2009 Stipendiat des Graduiertenkollegs CINACS


From my PhD work the startup HAPTOMAI was formed in late 2013. With our expertise in orientation, accessibility and tactile mapping, we help companies and organizations to develop products that are inclusive in the sense that they are designed-for-all.


Navigation support with tactile media, human-computer interaction, novel interfaces paradigms, HCI, interaction design.

Ph.D. Project

The goal of the ongoing doctoral research is to develop a concept of Cognitively-adequate Tactile Orientation Maps (CaTOM). Factors of geometry and topology that have an effect on tactile reading and comprehension of the underlying information were be identified and investigated. The result were recommendations how to abstract/generalize geographical data to produce better tactile environmental maps. For more information see See a complete list of publications from 2008 onwards at my project site. See my blog about my PhD project.

The "Workshop on Spatial Knowledge Acquisition with Limited Information Displays" at Spatial Cognition 2012 had successfully attracted interest. The workshop went very well which agrees with the feedback we received. The proceedings with all papers are published at and are available to anyone.

Previous & Current Work

After I had finished my first university studies, I worked for the Fraunhofer Gesellschaft as Usability Engineer in the FUN and the ReDSeeDS project as consultant and researcher at the IESE in 2006 and 2007. My main project was about how to design joy-of-use into the human-computer interaction. From 2008 on, I was engaged in the International Graduate Research Group on "Cross-Modal Interaction in Natural and Artificial Cognitive Systems" (CINACS) at the University of Hamburg. From summer 2010 until summer 2013 I was a doctoral student in the COSY group at the University of Bremen.

Aside from my research work to obtain a PhD, I work as usability engineer and information architect. I write about it in my blog about interaction design and user experience, for example when Donald A. Norman visited CoSy.


Now and then I teach courses on usability engineering and idea facilitation (creativity) techniques.
