Featured Projects
SUS.tools (2022 – Present)
The SUS tools constitute the most comprehensive usability evaluation toolkit that supports practitioners and researchers working with the System Usability Scale (SUS). It provides tools for creating SUS questionnaires in over 20 languages, calculating and benchmarking SUS scores, visualizing results, contextualizing data based on scientific literature, and calculating inferential statistics for entire SUS study datasets.
All tools of the toolkit are web-based, free, open-source, secure, and GDPR-compliant.
The Heb@AR App (2019 – 2022)
The Heb@AR App is an award-winning Augmented Reality (AR) training application that my team and I developed during BMBF Project Heb@AR. It offers five midwifery-specific training scenarios and is currently being deployed for self-directed and curricular on-site learning in several midwifery degree programs in Germany.
The app is available as an Open Educational Resource for handheld Android & iOS devices, and supplementary material is made available as open-source on GitHub.
TrainAR (2021 – Present)
TrainAR is a threefold combination of interaction concept, visual scripting-based authoring tool and didactic consideration toolkit for procedural Mobile Augmented Reality trainings. I developed TrainAR during my PhD project, and it was already used by several universities for teaching and research projects on Augmented Reality trainings and games like the Heb@AR, MarLab and Maries' ChemLab.
It is available open-source on GitHub, including comprehensive documentation.
Some more Mixed Reality and Usability projects I've worked on in research, industry, during hackathons, for startup programs, or in my spare time to open source them
Molly the Molecule
(2024)
“Molly the Molecule: The Acid Base Adventure” was a category-winning Mixed Reality prototype I worked on during the Global XR Hack. The idea was to have a chemical lab for pupils which lets them perform an experiment in AR and then “dive into” the molecular level in VR and interactively experience the chemical reactions. All this while “Molly”, an LLM-based AI agent, explains, guides and answers questions.
Ready Worker One
(2024)
I explored “Ready Worker One” during the EdTech Next Academy #5 of the Founders Foundation. The idea was to create a digital simulation of challenging oral language exams that all medical doctors coming to Germany have to take: the “Fachsprachprüfung”.
The project made it to the finals, and we pitched the idea to investors and a jury.
SUS Statistics Calculator
(2024 – Present)
The SUS Statistics Calculator is part of the SUS Analysis Toolkit, and an open-source web-based statistics tool that allows calculating the inferential statistics for System Usability Scale study results for common study designs with parametric and non-parametric statistics.
It is available at statistics.sus.tools,
for free and fully open-source.
SUS PDF Generator
(2022 – Present)
The SUS PDF Generator is part of the SUS Analysis Toolkit, and an open-source web-based PDF generator for System Usability Scale Questionnaires. With it, users can create interactive PDF questionnaires for 20 languages and variants of the SUS.
It is available for free at pdf.sus.tools, including the entire open-source code.
SUS Analysis Toolkit
(2022 – Present)
The SUS Analysis Toolkit is an open-source web-based analysis toolkit for the System Usability Scale, the most widely used Usability questionnaire today. It provides the most comprehensive functionality in terms of SUS calculation, plotting, interpretation and contextualization utility to date.
The toolkit is completely open-source and freely available at analysis.sus.tools.
Raumtänzer Flux XR
(2024)
Flux XR is a specialized Android, iOS and web Augmented Reality solution, developed by the Raumtänzer GmbH. It's designed for the machinery and plant engineering sectors, with the goal of elevating customer service as part of the company's Flux Suite. I was the Tech Lead for the Augmented Reality components of the solution and a member of the initiative's strategic steering committee in 2024.
GEMIT Mixed Reality Lab (2023)
As a Postdoctoral Researcher at the GEMIT Institute of the Niederrhein University of Applied Sciences, I conceptualized and designed the universities state-of-the-art Mixed Reality Laboratory, including didactic considerations, interactive 3D prototypes, and a research roadmap.
The concept included installations ranging from AR Assistance, over students working stations, to a Mixed Reality green screen cave.
AR Hydraulics Training
(2023)
During my time at the SMS group GmbH, I designed and developed an interactive AR hydraulics training. Through the combination of geometry processing of real components, hydraulic schematics, and interactive formula visualizations, it provides users with hands-on, interactive experiences that clearly demonstrate the inner workings of hydraulic systems used in large manufacturing machinery. This potentially improves understanding and operational efficiency.
Raumtänzer Flux Remote (2019 - 2022)
Flux Remote is a handheld Augmented Reality remote assistance application that is part of Flux Suite of the Raumtänzer GmbH and is available for Android & iOS Devices. It allows for interactive, Augmented Reality-based assistance video calls for industrial machinery and maintenance use cases. I conceptualized and developed early versions of Flux Remote during my time as a Software Developer at the Raumtänzer GmbH and accompanied its further development as a Scientific Consultant.
„Sonnensegel nach
Maß“ AR App (2021)
“Sonnensegel nach Mass AR”, an interactive Android & iOS Augmented Reality app that allows for in-situ sun sail visualization and customization, is a project I worked on during my time as a Scientific Consultant at the Raumtänzer GmbH. Here, I was responsible for the authoring aspects of Sail generation, customization and their in-situ placement.
LeARn: AR Programming serious game (2018)
“LeARn” was a prototype I worked on as the Tech Lead of a developer team during the 2018 Founders Hackdays at CITEC. The idea was a Microsoft HoloLens-based learning game that teaches basic programming concepts to children by connecting common programming logic blocks to cute animations.
ADAMAAS AR Glasses
(2017–2019)
The ADAMAAS Smartglasses were a research prototype for head-mounted Augmented Reality glasses (Microsoft HoloLens & Epson Moverio) to provide adaptive cognitive task assistance to elderly or impaired people. During my time as a Research Assistant in the Neurocognition and Action Group, I worked on the software implementations of the AR components of the ADAMAAS AR Glasses.
