Scanpath Comparison using ScanGraph for Education and Learning Purposes: Summary of previous educational studies performed with the use of ScanGraph

∗ The short paper describes the summary of previous studies from the area of education where a developed tool for scanpath comparison called ScanGraph has been used so far. This paper aims to introduce this freely available online tool to the community of eye movement researchers focusing on eye-tracking in education. ScanGraph allows calculation of similarity using Levenshtein and Damerau-Levenshtein algorithms and the Needleman-Wunsch algorithm (similar to ScanMatch). The results are visualized in a simple graph showing similarities among individual participants. The tool allows exporting similarity matrix, which might be further used for more detailed analysis. Moreover, it is possible to visualize similarity data calculated using the MultiMatch method. In the article, the tool’s functionality is described and introduced on the examples of case studies from the field of geographic education and physics.
