A visual analytics tool especially suitable for analyzing eye tracking data generated from dynamic stimuli. Gaze data of multiple viewers can be visualized and compared using the so called (gaze-guided) slit-scan technique. In the slit scan technique, individual strips of a visual stimulus are cut out and joined together along a timeline. The result is a compact and easily interpretable representation of the gaze behavior of a person. For more information about this technique, we refer to this publication:
Kurzhals, Kuno, and Daniel Weiskopf. "Visualizing eye tracking data with gaze-guided slit-scans." Eye Tracking and Visualization (ETVIS), IEEE Second Workshop on. IEEE, 2016.
- Visualization of gaze data based on the (gaze-guided) slit-scan technique and gaze-replay.
- Comparing gaze data with similarity measures.
- Data-mining methods and auxiliary visual components for better interpretation of similarity values.
- Comparing results of clustering based on dendrogram similarity.
Currently I only can recommend Linux (Arch-Linux and Ubuntu worked) for running this application. One reason is that the QT5-MultimediaModulue seems to have major problems on MacOS. For Windows systems I can not speak at this moment, but I'll give it a try in the future.
Things you need to have installed on your system:
- CMake (version >= 2.8).
- Qt5 application framework. Please make sure that your Qt version contains the Qt5Multimedia, Qt5MultimediaWidgets and Qt5Charts modules.
- OpenCV library (version >= 3.0).
Simply execute cmake . && make in the root directory of this project. If the build process succeeded, you can
find the exectuable in the gui/ folder.

This project emerged as a part of a bachelor thesis at the Visualisation Research Centre (VISUS) which is a central institution of the University of Stuttgart. Many thanks goes to Kuno Kurzhals for his great supervision.
