ScanGraph: A novel scanpath comparison method using graph cliques visualization
Original language description
The article describes a new tool for analysing eye-movement data. Many different approaches to scanpath comparison exist. One of the most frequently used approaches is String Edit Distance, where gaze trajectories are replaced by sequences of visited Areas of Interest. In cartographic literature, the most commonly used software for scanpath comparison is eyePatterns. During an analysis of eyePatterns functionality, we found that the tree-graph visualisation of its results is not reliable. Thus, we decided to develop a new tool called ScanGraph. Its computational algorithms are modified to work better with sequences of different length. The output is visualised as a simple graph, and similar groups of sequences are displayed as cliques of this graph. This article describes ScanGraph's functionality on a simple cartographic eye-tracking study example. Differences in the reading strategy of a simple map between cartographic experts and novices were investigated. The paper should aid researchers who would like to analyse the differences between groups of participants, and who would like to use our tool, available at www.eyetracking.upol.cz/scangraph.
