Parallel scan-path visualization

Abstract

Eye tracking analysis is the state of the art technique to study questions of usability and cognition of graphical user interfaces. This paper presents a new technique for the visualization of eye tracking data, the Parallel Scan-Path Visualization. A key feature is the visualization of eye movements of many subjects on a single screen in a parallel layout. The visualization presents various properties of scan-paths, such as fixations, gaze durations and eye shift frequencies at one glance. The paper concludes with an example of use of the Parallel Scan-Path Visualization technique.

A visual comparison of gaze behavior from pedestrians and cyclists

“…With the parallel scan path technique [Raschke et al 2012[Raschke et al , 2014, we found the longest sequence with five AOIs in the eye movement data of the pedestrians: junction right -shoulder check left -junction right -pavement far -parking line. Figure 4 shows this sequence.…”

“…This allows us to receive more detailed and accurate data. Additionally, we use the parallel scanpath visualization by Raschke et al [2012; to search for common sequences in the eye movement data.…”

“…Additionally, we analyze common sequences of AOIs using the parallel scan path method [Raschke et al 2012[Raschke et al , 2014. This parallel visualization of video recordings and eye movement data allows us to identify interesting sections for different traffic situations visually.…”

Towards visualizing eye movement data from interactive stimuli

“…Furthermore, different visualization techniques for eye movement data have been developed at the institute. Some examples are the parallel scan path visualization technique [Raschke et al 2012], AOI rivers [Burch et al 2013], the circular heat map transition diagram [Blascheck et al 2013a] (cf. Figure 2), or time compensated heat maps [Kurzhals and Weiskopf 2013].…”

Space-Time Visual Analytics of Eye-Tracking Data for Dynamic Stimuli

“…Tsang et al [43] provide a tree-like visualization for the exploration and comparison of sequential gaze orderings. Raschke et al [32] introduced the parallel scan-path visualization to facilitate the comparison of eye-tracking data between several users. In the context of visual analytics, Andrienko et al [5] provide a detailed methodology for eye-movement data.…”
