“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 what is happening. All this while having “Molly”, an LLM-based AI agent, explain, guide and answer questions.

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 all common study designs with parametric and non-parametric statistical tests.

It is available at statistics.sus.tools,
for free and fully open-source.

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 am currently the Tech Lead for the Augmented Reality components of the solution and a member of the initiative's strategic steering committee.

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 sus.tools

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.

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.

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.

“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.

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.

“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.

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.
