The wide availability of digital reading material online is causing a major shift in everyday reading activities. Readers are skimming instead of reading in depth [Nielson 1997]. Highlights are increasingly used in digital interfaces to direct attention toward relevant passages within texts. In this paper, we study the eye-gaze behavior of subjects using both keyword highlighting and ScentHighlights [Chi et al. 2005]. In this first eye-tracking study of highlighting interfaces, we show that there is direct evidence of the von Restorff isolation effect [VonRestorff 1933] in the eye-tracking data, in that subjects focused on highlighted areas when highlighting cues are present. The results point to future design possibilities in highlighting interfaces.
