About the project

The project 'Gaze sharing to support social navigation and guidance' is associated with the DFG Research Training Group - User-Centred Social Media, at the University of Duisburg-Essen. Innovative man-machine interfa-ces that also utilise the recording, evaluation and mirroring back of eye tracking are considered.

Within this project the development and testing of algorithms for the analysis of eye tracking data is essential. The necessary knowledge and data are obtained in realistic scenarios within empirical studies. The starting point is the domain of computing education research into source code comprehension. The observation and analysis of students in solving comprehension tasks, based on Java source code, is a realistic scenario not only for universities. It is also highly relevant in the current situation of teaching of computer science and computer science-related study programs.

The studies carried out to date prove that learners may encounter a variety of difficulties in understanding the structure and content of a source code. The parts to be problematic for an understanding of the code may be provoked, for example, by so-called “code smells”, in which certain constructs in the source code do not correspond to the stan-dard of the respective language. Another study shows that the structure and the manner in which the source code is being presented (visualization), can lead to obstacles in understanding the source code. A further study proves that different help systems will lead to a better understanding and to practical applications by test persons, as was shown in interviews and by performance data (see fig.).
The data achieved in the conducted studies show that test persons can develop an understanding for a variety of obstacles, that the source code may be perceived very individually and that support systems may be used very differently. The gained data and findings can be used in studies and research projects beyond the dissertation project to create and explore systems that support a comprehension of programmes.

The research work is the object of the dissertation by Fabian Deitelhoff with the title “Developing Eye Tracking Methods for Detecting Course Code Comprehensive Strategies”. Fabian Deitelhoff successfully defended his cooperative dissertation with the University of Duisburg-Essen in December 2020.
