ABSTRACT

Multiple-view visualisation leads to additional switching cost on attention management between viewports. In this study, we compare the cueing effect of chromatic and achromatic colours on mitigating viewport switching cost in multiple-view visualisations through the dual-task paradigm. There is a concurrent need for managing attention within and between viewports, and performing a three single-digit mental addition task, which poses challenge for the capacity-limited working memory (WM). Response time and total fixation count support the benefit of chromatic colours in within-viewport attention management. First-pass progressive fixation time reveals that chromatic colours lead to better coherence within the viewport than achromatic colours, and there exist a correction process for attention misguidance in invalid cueing conditions. We employed re-visitation count and duration as direct measures of WM reinstatement. Fewer re-visitation count and shorter duration in the valid chromatic cueing condition indicate that more WM resources were freed up for the primary task, and reduced resources were depleted on overcoming the viewport switching cost. The positive role of valid chromatic colour cues become increasingly evident when more viewports presented simultaneously. The study provides eye movement evidence that chromatic cues can effectively lessen the switching cost on attention management in multiple-view visualisations.

摘要

多视图可视化导致视口之间注意力管理的额外切换成本。在这项研究中，我们通过双任务范式比较了彩色和非彩色对减轻多视图可视化中视口切换成本的提示效果。同时需要管理视口内和视口之间的注意力，并执行三个个位数的心理加法任务，这对容量有限的工作记忆 (WM) 提出了挑战。响应时间和总注视计数支持彩色在视口内注意力管理中的优势。首过渐进固定时间表明，彩色比无彩色在视口内具有更好的连贯性，并且存在针对无效提示条件下的注意力误导的校正过程。我们采用重访次数和持续时间作为 WM 恢复的直接衡量标准。在有效色彩提示条件下，更少的重访次数和更短的持续时间表明更多的 WM 资源被释放用于主要任务，并且减少的资源在克服视口切换成本时被耗尽。当同时呈现更多视口时，有效彩色提示的积极作用变得越来越明显。该研究提供了眼球运动证据，表明色彩线索可以有效地降低多视图可视化中注意力管理的转换成本。并且减少的资源在克服视口切换成本时被耗尽。当同时呈现更多视口时，有效彩色提示的积极作用变得越来越明显。该研究提供了眼球运动证据，表明色彩线索可以有效地降低多视图可视化中注意力管理的转换成本。并且减少的资源在克服视口切换成本时被耗尽。当同时呈现更多视口时，有效彩色提示的积极作用变得越来越明显。该研究提供了眼球运动证据，表明色彩线索可以有效地降低多视图可视化中注意力管理的转换成本。
