I am post-doctoral researcher at the Innovative Retail Laboratory (IRL) led by Prof. Dr. Antonio Krüger at the German Research Center for Artificial Intelligence (DFKI) in Saarbrücken, Germany. My main research is in the field of human-computer interaction, 3D user interfaces and ubiquitous sports technologies.
At DFKI, I am working in the EIT ALIGRE project. The ALIGRE project investigates how lighting can help to attract shoppers to certain areas in grocery stores. It project provides new, more advanced retail lighting solutions, using light zoning and semantic lighting. The benefits are supported by real-life test installations and accompanying user study in an operational grocery store.
I was Marie Curie Early Stage Researcher at the School of Computing and Communications in Lancaster, UK. At the School of Computing and Communications I was working on in the group of Prof. Hans Gellersen. Besides developing a post-doc research profile I explored gaze-based interaction.
In 2015, I defended my doctoral thesis on "Interaction with Stereoscopic Data on and above Interactive Surfaces". In 2008, I received a diploma in geoinformatics at the Institute for Geoinformatics, University of Münster, Germany.
I have working experience in organizing different workshops and conferences, e.g. the "CHI SIG Touching the 3rd Dimension" and was also involved in the follow-up CHI workshop "The 3rd dimension of CHI (3DCHI)" and the Dagstuhl Seminar "Touching the 3rd dimension". I organized the Tutorial and Workshop on Interactive Surfaces for Interaction with Stereoscopic 3D (ISIS3D) at ITS 2013. In the context of my Ubiquitous Sports Technology research I organized the UbiMount Workshop at UbiComp 2016 and I am co-organizer of the CHI 2017 SIG on Interactive Computing in Outdoor Recreation.
I was Web and Social Media Chair at the ACM Symposium on Spatial User Interaction (SUI) 2014 and ACM Symposium on User Interface Software and Technology (UIST), Publication Chair at UbiComp 2016 and PC Member at the ITS 2015, IUI 2015 and IUI 2016. Currently, I am Poster Chair at the SUI 2017 PC and serve as a PC Member at CHI PLAY 2017.
This doctoral thesis project evaluated multi-touch and gestural 3D interaction on and above interactive surfaces and explores the design space of interaction with stereoscopic data.

Affective lighting for novel grocery retail experiences
This ALIGRE project will test and validate the effect of the new lighting solutions on the shopping experience using highly advanced sensor and data analytics tools, thereby creating the necessary quantitative proof points to commercialize the propositions. The benefits are supported by real-life test installations and accompanying user study in an operational grocery store.
Touching the 3rd Dimension
Although stereoscopic multi-touch enabled surfaces induce several perceptual conflicts, e.g. visual-haptic or accommodation-vergence conflicts, it is reasonable that they will further dominate future user interfaces in various settings due to their potential as well as attractiveness for human users. So far most approaches have not taken into account the mentioned perceptual conflicts and are in most cases limited in their focus on the actual moment of touch (i.e. when the finger touches the surface), whereas the essential time period before the touch is rarely considered. Obviously - in the case of stereoscopic display - these moments are particularly important since most virtual objects are rendered not on the surface, but before or behind it. Hence, usually touching virtual objects and touching the physical surface occur at different moments during the interaction. The benefits, challenges and limitations of using this combination have not been examined in-depth and are so far not well understood.
The project Touching the 3rd Dimension (T3D) therefore aims to address these questions by analyzing the perceptual aspects during the lifetime of a touch, i.e. the pre-touch, as well as the actual touch phase. On the one hand we intend to design and evaluate different interaction concepts for stereoscopic multi-touch enabled surfaces based on perceptual limitations of the user, and on the other hand we will exploit our setup to gain novel insights into the nature of touch and perception in the real world. In addition we will explore potential application areas, in particular 3D modeling in the domains of city modeling and computer-aided design (CAD).
Multi-modal interaction with distant objects using eye gaze and multi-touch input
Interscopic Multi-touch Surfaces
Multi-touch interaction has received considerable attention in the last few years, in particular for non-immersive, natural 2D interaction. Some multi-touch devices even support three degrees of freedom (DoF) in terms of 2D position on the surface and varying levels of pressure. Since multi-touch interfaces represent a good trade- off between intuitive, constrained interaction on a touch surface providing tangible feedback, and unrestricted natural interaction without any instrumentation, they have the potential to form the fundaments of the next generation 2D and 3D user interfaces. Stereoscopic display of 3D data provides an additional depth cue, but until now challenges and limitations for multi-touch interaction in this context have not been considered. In this project we aim to develop interscopic multi-touch user interfaces. An interscopic multi-touch surface (iMUTS) will allow users to interact intuitively with stereoscopically displayed 3D objects and with usually monoscopically displayed 2D content.
Service-orientierte ArchiteKturen zur Unterstützung von Netzwerken im Rahmen Oeffentlicher Sicherheit (Service-Oriented ArchiteCtures Supporting Networks of Public Security)
SoKNOS developed data-based solutions that particularly shorten the structuring phase, i.e., the phase after the occurrence of the disaster. SoKNOS aimed to support a cross-organizational collaboration – in real-time and on all levels between local, regional, national, and international organizations.
