smearsafe
a smudge-resistant authentication mechanism for touch-enabled devices; uses graphical passwords and geometric transformations.
snapapp
a novel unlock concept for mobile devices that reduces authentication overhead
behavioral biometrics
compares different touch targets regarding their suitability to identify users from their touch behavior
gravity spot
an approach to guide users to a sweet spot in the vicinity of a large display.
pedestrian cruise control
a navigation system that allows pedestrians to be controlled using electrical muscle stimulation.
midair displays investigates the concept of free-floating displays that approach the user. Scenarios include emergency evacuation, sports, and group applications.
framebox and mirrorbox

 

two low-fidelity prototyping tools to support the design and creation of 3D layered user interfaces.
looking glass investigates the efficiency of the user’s mirror image and his silhouette as an interactivity cue for large public displays.
digifieds
a digital public notice area that allow users to exchange and retrieve content on public displays; used to investigate different interaction techniques.
unidisplay
a research prototype to investigate the users’ expectations towards public displays; we are particularly interested in the moderation process.
audience funnel
a model that allows the efficiency of interactive display applications to be quantified; defined different interaction phases and thresholds to be overcome.

I am a full professor in Usable Security and Privacy at the Bundeswehr University in Munich. My research interest is in behavioural biometrics, novel threat models that emerge from ubiquitous technologies, and social engineering. Further research interests include novel interfaces on physiological sensing (in particular, eye gaze and brain-computer interfaces), automotive user interfaces, virtual reality and interaction in public space.

Before, I worked as an assistant professor in human-computer interaction at the LMU Munich, where I headed the Ubiquitous Interactive Systems Group. In addition, I was a research group leader at the HAW Munich in the context of the Biometrics++ project. I did my PhD studies at the University of Stuttgart (2011-2013) and at the University of Duisburg-Essen (2008-2011) with Albrecht Schmidt.  I was a guest lecturer for “Pervasive Computing” (Essen, 2012) and for “Unconventional User Interaction” (JKU Linz, 2013). I worked as a visiting researcher with Jörg Müller at T-Labs in 2011. I hold a Ph.D. from the University of Stuttgart (Thesis Topic: A Design Space for Pervasive Advertising and Public Displays) and a diploma in media informatics from the University of Munich (LMU München). I completed my master thesis at the Fraunhofer Institute for Intelligent Analysis and Information Systems (IAIS) and at the University of Bonn (b-it). During my studies I also worked as a web developer for Pinnacle Systems Inc. (Mountain View) for nine months in 2005. After my studies I worked for 6 months at Schreiner MediPharm LP (New York) as an IT specialist.

News

Effective 1 May 2019 I accepted a position as full professor at the Bundeswehr University, Munich.

I committed to be the general chair for MUM 2018 and program chair of Mensch und Computer 2019.

We got six papers accepted at the CHI 2018 conference, two of which received a Best of CHI Honorable Mention Award.

Lots of interesting commitments: I will serve again as AC for CHI 2019 and am a member of the editorial boards of IMWUT and IEEE Pervasive Computing.
