The Movie Landscape application uses a 3D interface representing a landscape metaphor to enhance user preference elicitation in large information spaces.
We regularly develop custom applications or prototypes for research purposes. Some of them are listed below. These developments are often inspired by our funded research projects. On the respective detail pages, you will find more detailed information such as related publications or contact persons.
Move My Day is an Android app, counting steps in daily life and serving as a tool for investigating issues related to motivation for physical activity. It is available in Google Play Store.
An overview and experience-based advise for concrete methods and tools we found helpful in the Gameful Design Process.
The Gamification Engine Kinben is a RESTful service meant to support engineers gamifying working processes. This project open source project is available on GitHub.
An interactive recommending approach that combines the beneﬁts of user-generated tags with those of automatically derived latent factors and that allows users to control recommendations via tags.
Hootle is a hotel recommender system developed to study an approach to group recommendations from the point of intersection of traditional group recommenders and group decision making theory.
MyMovieMixer is an interactive movie recommender that demonstrates the approach of Blended Recommending by integrating interactive information filtering and algorithmic recommender techniques.
The cognitive training environment Merobrixx is a serious game, based on traditional mental rotation training methods. Players interact with the game by means of a Tangible User Interface, which consists of three-dimensional objects.
The BFBC2 Persona Visualizer is a prototypical tool for displaying the tendency towards certain play styles of people playing the video game Battlefield: Bad Company 2.
X3S defines a workflow that requests data from a SPARQL endpoint, restructures the result into a hierarchical XML structure, transforms this structure via XSLT into HTML and styles the HTML document with CSS.
MIA is a collection providing tools for improving and personalizing the in-car navigation. Therefore web-based services are used in order to support the driver with additional information incorporated in the route guidance. Furthermore, it contains utilities that take the drivers spatial knowledge of the environment into account and adapts the verbal driving instructions according to this knowledge.
To develop games in a rapid, easy and efficient way is the goal of the 2DGree game protoyping framework. The framework supports game designers who are in the need of rapid game prototyping tools to test their ideas in early project stages as well as interested gamers who like to play around with their ideas and bring them to life.
Hybreed is a software framework for building complex context-aware applications including a set of components for developing recommender systems. It is based on a concept for processing context that we call Dynamic Contextualization.
With ChainGraph we present a new approach to graph visualization that displays resources and their shared properties in chains to prevent dense graphs and to better support the exploration of relationships.
DISCOVR is a showcase of a shopping portal that aims at providing the visitor with better user- and context-aware recommendations for products and events than is possible with traditional recommendation algorithms such as collaborative filtering. In contrast to SPREADR, however, DISCOVR does not focus on spreading activation-based recommendation generation.
RelFinder extracts and visualizes relationships between given objects in RDF data and makes these relationships interactively explorable.
gFacet is a new approach to explore RDF data by combining graph-based visualization with faceted filtering techniques. Facets are represented as nodes in a graph visualization and can be interactively added and removed by the users in order to produce individual search interfaces.
SPREADR is a prototype of a context-aware shopping portal incorporating a series of spreading activation-based adaptation techniques to recommend products to the user that would not only fit to his or her personal preferences, but also to the current usage context. Starting with a set of automatically determined internal or external context factors like the user’s click history, the current season or upcoming holidays, the system spreads ‘activation energy’ to related concepts that are modeled using a pre-defined vocabulary in an ontology.
Grimmix is a Java computer game abot the fairy tales of the Brothers Grimm, which is connected to a storytelling engine based on Prolog and Bayesian Networks.
AR Tierchen is an interactive game, demonstrating the potential of augmented reality that uses an intuitive tangible user interface that is intuitive for the users as well as algorithms for image recognition.
