Introduction of the Research Group

At the CHI 2004 conference, the Research Group of the Department of Ergonomics and Psychology, BME, presented the Human-Computer Interaction Research Group, looking back at its already colourful experience. The members of the group have since carried out research and development projects on the usability of software for industrial partners and a series of experiments on human behavior in a framework of projects with international partners. The partners of our software usability projects included Magyar Telekom, Ericsson, Generali-Providencia Insurrance, and Graphisoft. In our international research projects, a frequent partner is the University of Maryland Baltimore County (UMBC), including researches on the interactions of users in a virtual reality (VR) environment. The strength of the research group is the application and development of a wide palette of empirical usability testing methods including eye-tracking, measurement of heart rate variability to examine mental effort, team-level usability testing.

Achievements

- Complex application and methodological development of empirical usability testing in various application areas from video and behavioral coding -based methods to eye-tracking and measurement mental effort based on heart rate variability
- Achieving better time resolution than others measuring mental effort based on heart rate variability: in practice, we can indicate the required effort or easiness of interactions of a 5-6 second time-frame, not only in the laboratory, but even in a noisy work environment
- Application of the eye-tracking -based usability testing method in non-traditional areas: e.g., testing 3D software, virtual reality (VR), tangible (non-IT) products
- Development of team-level usability testing methodology
