查询式序列视角下跨设备搜索信息准备与重用阶段的眼动变化研究

Change of Gaze Behavior in Information Preparation and Resumption of Cross-Device Search Based on Query Lists

在信息检索领域中,用户在搜索引擎结果页面的眼动行为一直受到研究者的关注;特别是在跨设备搜索、跨屏交互日益普遍的背景下,用户发生设备转移后在SERP上的眼动行为分析已成为一个研究热点。在复杂搜索任务中,用户会提交多个查询式,而现有研究缺乏基于查询式序列的角度分析用户SERP 眼动行为。本文通过在实验室环境下,开展用户实验,收集用户在跨设备搜索任务中的信息准备和信息重用两个阶段的眼动数据,从基本眼动现象、时间维度现象、空间维度现象三个层次,分析实验用户在SERP上眼动注视行为的变化。研究发现“信息重用”阶段中,用户在SERP 上的注视时长、关注点数量,相比“信息准备”阶段都有所降低;注视区域的演化规律也发生了变化;眼跳次数、回视次数等指标也普遍降低;支持用户跨设备网络搜索的工具能够有效降低用户的眼动视觉负荷。

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 users ?? gaze 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.
