导视地图界面维度差异下的视觉搜索效率研究

Research on Visual Search Efficiency under the Difference of Interface Dimension of Guide Map

图像的维度差异会对用户的信息获取及视觉交互效率产生一定程度的影响,以导视地图界面设计为例,建立三种不同维度的地图样本,利用眼动追踪实验收集用户搜索指定目标时的眼动数据进行分析,同时基于SUS系统可用性量表收集用户主观感受数据。结合定性与定量方法,比较分析了不同维度的地图呈现下用户的视觉搜索效率高低与规律差异,结果表明:在2D的呈现方式下,用户的综合搜索效率最高,而随着界面维度的升高,用户的搜索行为因受到透视因素干扰,综合搜索效率逐渐降低。

The dimensional difference of images will have a certain degree of impact on the user's information acquisition and visual interaction efficiency.This paper takes guide map interface design as an example,establishes map samples of three different dimensions,uses eye tracking experiment to collect the eye movement data of users searching for a specified target for analysis,and collects user's subjective feeling data based on the SUS system usability scale.Combining qualitative and quantitative methods,this paper compares and analyzes the user visual search efficiency and rule differences in map presentation with different dimensions.The results show that user comprehensive search efficiency is the highest in 2D presentation mode,while with the increase of interface dimension,the user's search behavior is affected by perspective factors,and the comprehensive search efficiencygraduallydecreases.
