Abstract  The visual gaze behavior of SERP (search engine result pages) users is important in the field of information retrieval. Specifically, as the popularity of cross-screen interaction and cross-device web searching increases, the adjustments to a user’s gaze behavior during device transition have become a hot research topic. Users will submit a series of queries when facing a complex search task, but research is lacking about the usersgaze behavior based on their perspectives of those queries. This paper collects eye movement data while performing cross-device web searches during user experiments, including basic eye movement, time dimension, and spatial dimension phenomena. The results reveal that both the gaze duration and gaze count in “information resumption” are lower than in “information preparation.” The evolution of the gaze region also changed, and both the saccade and regression counts are generally reduced. In addition, tools that support a user’s cross-device web search can effectively reduce eye movement load.
