Research and development

The Interactive Systems group provides different services within our areas of expertise. Our research, development and consulting services aim at both industry and research partners, and we have an extensive track record of R&D cooperations. Our areas of service include (but are not limited to):

Eye Tracking Analysis

The usability lab of the Interactive Systems research group features an eye tracking system, which measures eye positions and eye movement. Based on the data the system is able to generate gaze plots of single persons or heatmaps and gaze plot visualizations of groups of test subjects. Moreover, areas of interest can be defined and evaluated in terms of observation time, time to first fixation or the number of fixations. The eye tracking system can be used for web usability and software testing, market research and advertising impact, product placement and within the area of interface design and adaptive systems.

Interactive Application Development and Consulting

The development of interactive applications offers a huge variety of challenges: Which platform shall the development focus on? What will be the technical foundation of the application? Which interaction paradigms fit best for the chosen target group and application context? Our team will help and guide you through the process of developing your interactive application and support your decision-making process by providing our expertise within this area.

User Experience and Usability Testing

The common method of usability testing is a well-established technique in the area of user-centered design to evaluate a product through user tests. At our usability lab we provide usability tests with e.g. video tracking, keyboard and mouse input logging, eye tracking and audio feedback recording. We can provide help with the design of the study, recruit test subjects, conduct the study and provide detailed results and an analysis afterwards. Next to the user experience testing within the area of traditional software engineering our team has extensive knowledge in the evaluation of interactive entertainment products and performs player experience tests, collects and analyzes game metrics and offers evaluations based on game usability heuristics.

User Interface Design and Prototyping

Our group has a longtime experience within the area of user interface design and prototyping and provides services alongside the whole development cycle of a software product. We support software developers and researches within the requirements or stakeholder analysis, generate mock-ups, paper and software prototypes and offer different usability engineering methods to evaluate the user experience throughout the design and development process.
