摘要

We introduce a visualization technique called color bands for showing the time-varying eye movement behavior of eye-tracked people. Our contribution is the clutter-free representation of time-varying x- and y-positions of gaze data. We map these coordinates to vertical positions from left to right as in traditional line plots. On top, we display the differences between the x- and y-coordinates by the thickness of the band. Fixation durations are visually encoded as circles of varying diameters. Color coding is used to additionally enhance the distance values and the durations in order to perceptually benefit from pattern recognition for an individual participant but also to compare the eye movement behavior of several participants. We illustrate the usefulness of our technique in a case study investigating eye movements from a formerly conducted eye tracking study on the readability of node-link tree diagrams.
