摘要
知识地图的可获取性是近年来越来越被重视的评价指标。采用E-Prime呈现视觉刺激材料,ASL眼动仪采集30名被试者的眼动实验数据,考察被试者的首视点在不同界面以及隐含分区的分布,用实验的手段证实了信息出现在界面的不同位置带给使用者的认知负荷不同。针对信息密集的知识地图,合理降低认知负荷是增强知识地图可获取性的有效途径。
The availability of knowledge map is paid more and more attention to by researchers in recent years.We provide visual stimulated matter by E-Prime,collect data of 30 subjects by ASL eye-tracker,and observe the distribution of first fixation point in different page layout and implicit partition.By the data and distribution,the paper discusses different location at which information appear can bring different cognitive load to the user.To knowledge map which is information-intensive type,reasonably reducing cognitive load is an effective way to improve the availability of knowledge map.
