鉴于信息可视化系统的蓬勃发展，丰富的交互性是用户获取更深入和有洞察力的信息所必需的。鼠标悬停已被广泛用于提示有关悬停元素的交互或细节。然而，在我们设计的基于层次化Sankey图的鼠标悬停可视化系统中，我们观察到鼠标悬停效应干扰了用户点击项目，从而降低了交互的效率，并将信息隐藏在下一个级别。本文考察了这种情况，并研究了不同的鼠标悬停提示对邀请点击的启示的有效性。我们确定了四种类型的感知负担，并创建了七种设计，采用机械土耳其人来衡量有效性。结果显示，七个设计中有五个显著提高了用户的点击率，而超过60%的用户在没有适当的负担能力提示的情况下未能点击悬停元素以显示下一级别的信息，即使他们多次刷过这些元素也是如此。通过比较不同设计的性能，我们提出了支持可视化设计可靠性和互动性的指导方针。
Given the thriving of information visualization systems, rich interactivity is expected and essential for users to acquire further and insightful information. Mouseover has been widely used to hint interactivity or details about the hovered elements. However, in a mouseover-click visualization system we designed based on a hierarchical Sankey diagram, we have observed that a mouseover effect interfered users from clicking items and hence reduced the efficacy of the interaction and hid the information in the next levels. This paper examined this situation and studied the effectiveness of different mouseover hints on affordance for inviting clicks. We identified four types of perceived affordances and created seven designs, adopting Mechanical Turk to measure the effectiveness. Results showed that five out of the seven designs significantly improved users’ click-through rate, whereas more than 60% of users failed to click the hovered elements for revealing the next level of information without proper affordance hints, even after they brushed over these elements for multiple times. By comparing the performance of different designs, we proposed guidelines that support the reliability and motivate the interactivity of visualization design.
