Scientific Services

Dr. Stein develops concepts for knowledge transfer games, Serious Games and Gamification. He is also involved in software development, implementation and testing. He also offers workshops on VR and games as a cultural technique.

The following software projects were all developed iteratively and agilely in an academic context according to Dr. Stein's conception. In addition, they were tested and published under his leadership and represent a significant part of his publications.

Mein Objekt

  • Mein Objekt

    is an innovative museum game that enables visitors to engage in dialogue with objects, seeking to transform digital habits into cultural interest. Using machine learning and adaptive language, an adaptation of the application to the individual visitor is ensured, resulting in a personalized, interest-driven museum tour. The project was developed for the Humboldt Forum as part of museum4punkt0 and will be used there for the first time when it opens. It is developed in React Native and is used BYOD for Android and iOS.

 Diary

  • Diary is a tool for exploring scientific interdisciplinary work and has been developed for the Experimantalzone of the Cluster of Excellence Image Knowledge Gestaltung to better understand interdisciplinary collaboration. It is developed for macOS in Objective-C and can record, visualize and synchronize activities such as software usage, keystrokes, activity cycles and more with a server. It is used to explore digital working practices and habits across disciplines and also benefits users in terms of self-reflection on their working practices.

iWrite

  • iWrite is a gamified tool to improve scientific writing processes. It is developed for macOS in Objective-C and allows the user to organize writing processes into focused sessions, eliminate distractions, visualize progress, and schedule writing sessions. It also unlocks step-by-step tips and videos from writing experts.

BWG VR

  • BWG VR is an interactive, stereoscopic 360° experience for virtual reality headsets that shows the Cluster of Excellence Image Knowledge Gestaltung in its various spaces and presents actors of the cluster exemplarily in their working environments. The connection between space, objects and people is presented and the complex configuration of different actors is made tangible.

Singleton

  • Singleton is a game for integrating personal goals into everyday life and individual development based on self-imposed priorities based on theoretical principles from psychology and game studies. It is developed in Unity Mobile for Android and iOS and allows entertaining and goal-oriented microinterventions in a level system based on individually generated card decks. It is based on the Big 5 character traits and dynamically assigns specific card packs individually to the user.

ID+Lab

  • ID+Lab is the prototypical front-end of a publication platform designed to publish interdisciplinary research as a network and to show connections that otherwise remain hidden. It is developed as a web application and is based on Semantic Web technologies with GraphDB in the background. Publications are modeled here as a semantic network and visualized dynamically and intuitively. A DFG research proposal to deepen the project is currently under review.

Reading Revisited

  • Reading Revisited is a VR application that tests reading in virtual reality and dynamically integrates various texts into moving landscapes. It explores the question of what influence reading environments have on comprehension and memorization and whether text can be thought of as a combination of environment and reading. Texts from the cooperating publisher Merve Verlag can be read and experienced in VR and can be received in a specially developed environment.

Bee Virtual

  • Bee Virtual is a collaborative VR application in which two subjects control virtual bees by gaze direction and steer them through a virtual space. It was developed in Unity 3D for Oculus Rift. This is modeled on the physical space of the Central Laboratory Room of the Cluster of Excellence Image Knowledge Gestaltung. In an experimental setting, it was investigated how objects are remembered in VR, how virtual spaces can be transferred to physical ones, and to what extent communication among the test subjects influences the remembering of environmental properties.

PlosOne Metadata Extractor

  • PlosOne Metadata Extractor is a browser plugin that extracts metadata in lists of PlosOne publications including abstracts, making them processable and analyzable for text mining.

Decide & Survive

  • Decide & Survive is a game that makes it possible to experience decision-making processes in foreign policy contexts and aims to investigate the influence of user interfaces on player decisions by using both aggressive and neutral interfaces and sounds. It is developed in Java with JavaFX and runs server-side via PHP.

OncoLogg

  • OncoLogg is a game designed for multiple myeloma patients and their families to educate them about therapies, risks and side effects. It lets the player experience different therapy cycles and refocuses from healing to achieving life goals. The game was developed together with the Charité in Java for Android.

iglos

  • iglos, or the Intelligent Glossary, is a semantic network design application intended to identify and facilitate terminology and comprehension problems in interdisciplinary academic projects. It is browser-based developed with web technology and RDF/OWL compatible.

Expertise

Prof. Weidlich is a professor at the Department of Computer Science, where he leads the Process-Driven Architectures research group. The goal of his team is to support and improve the design and the analysis of process-oriented information systems (POIS) and event-driven systems (ES). POIS are software systems that help to automate, monitor, and control processes. These systems are established in various domains, from logistics, through healthcare, to infrastructure monitoring. The team’s research focuses on formal methods for behavioural modelling and verification, event-driven approaches to monitor and control processes, as well as questions related to process-driven data integration. The group further works on techniques that optimise the run-time behaviour of event-driven systems. In particular, the evaluation of event queries over streams can be designed more efficiently once regularities within event streams have been detected. In 2016, Prof. Weidlich was named Junior Fellow of the German Informatics Society (Gesellschaft für Informatik, GI) and awarded with the Berlin Research Prize (Young Scientist) by the Governing Mayor of Berlin.

Our daily life more and more depends on computational systems embedded in common appliances. Just think of advanced driver assistance systems in cars, medical devices, or indsutrial supervisory control and data acquisition systems. Since such systems also realise safety-critical tasks, it is all the more important to provide effective and efficient quality assurance for them. The specification, verification and testing theory group researches methods for model-based development and model checking, logical verification, and automated testing of safety-critical software. Prog. Schlingloff is chief scientist of the system quality center at Fraunhofer FOKUS, Berlin, and chairman of the boards of GFaI e.V. and ZeSys e.V.

Expertise

The structure research and electron microscopy group at the HU of Berlin actively develops and applies a broad spectrum of techniques for the analysis of small volumes of material by transmission electron microscopy (TEM), scanning transmission electron microscopy (STEM), scanning electron microscopy (SEM), and also light microscopy. Know-how which we can offer to external partners is based on the development of radically new electron diffraction techniques for ab-initio determination of atomic structure in (nano-) crystalline materials, and also the development of inline holographic techniques for the TEM as well as the optical microscope. The inline holographic techniques developed within the group are applied in the TEM for mapping electrostatic potentials, charge density distributions, and also strain in semiconductors and ceramics. In the optical microscope we apply these techniques for quantitative phase microscopy of living cells or mapping the topography of surfaces with nm resolution along the optical axis.

Model-driven Software Engineering

Expertise

Model-driven engineering raises the level of abstraction in software engineering by using models as primary development artifacts. In particular, domain-specific modelling languages can ease the transition between informally sketched requirements or designs and implementations by supporting high-level yet formal representations as a starting point for automation. Moreover, using a model-based development approach, critical system properties can be analyzed, validated and verified even before the system is actually built. Model-driven development thus leads to an increase in both productivity and quality. To some extent, model-driven engineering has made its way into industrial practice, most notably for the development of embedded systems in various domains. However, model-driven engineering does not suffice to successfully manage all challenges of modern software engineering, and actually creates new problems. Research conducted at the Chair of Model-driven Software Engineering is particularly driven by relevant challenges and problems arising from the adoption of the model-driven engineering paradigm in industrial practice.

Scientific Services
  • Experience in implementing model-based development engineering methods, techniques and processes
  • Know-how regarding the set-up of model-based transformation chains (domain-specific modeling languages, model transformation and interpretation, code generation) and development environments (collaborative modeling, (co-)evolution of models, model repair and synchronization)
