1. A method for analyzing eye tracking data, the method comprising:
- receiving the eye tracking data at a path analysis system, wherein the eye tracking data comprises a plurality of scanpaths, each of the plurality of scanpaths representing a sequence of visual fixations on a stimulus image;
generating, with the path analysis system, a sequence of tokens corresponding to the sequence of visual fixations;
generating a dotplot, with the path analysis system, using the sequence of tokens; and
identifying, with the path analysis system, one or more patterns of sequentially matching tokens within the eye tracking data based on the dotplot.

Abstract
Embodiments of the invention provide systems and methods for analyzing eye tracking data. The eye tracking data can represent a number of different scanpaths and can be analyzed, for example, to find patterns or commonality between the scanpaths. According to one embodiment, a method of analyzing eye tracking data can comprise receiving the eye tracking data which can include a plurality of scanpaths, each scanpath representing a sequence of regions of interest on a stimulus image. A dotplot can be generated and can include each of the plurality of scanpaths. One or more patterns within the eye tracking data can be identified based on the dotplot.
