AI 中文摘要
按需详情是可视化设计中常见的设计模式，在与视觉饱和或小型显示屏交互时尤其有用。除可视化外，针对饱和显示屏的另一种常见方法是整合其他模态，例如触觉反馈。虽然可视化中的触觉渲染主要针对无障碍需求，将触觉作为视觉反馈的替代方式，但在可视化语境之外使用触觉的研究已显示其在体验因素方面的价值，例如在模糊语境中提升信心、增强参与度。我们探索将振动反馈作为补充信息通道，用于传达触摸屏上按需详情工具提示中的趋势。我们通过一项研究确定了触觉编码的首选参数配置，该研究中参与者识别出他们认为最准确反映工具提示中折线图动态的参数配置。在第二项研究中，我们评估了参与者在配对比较任务中的表现，发现加入振动编码可提升参与度且不影响准确性。我们讨论了这些发现对未来可视化设计的启示，并提出了应用方向和未来研究的方向。
英文摘要
Details on demand is a common design pattern in visualization design, especially useful when interacting with visually-saturated or small displays. Beyond visualization, another common approach for saturated displays is to incorporate other modalities, such as haptic feedback. While haptic rendering in visualization has primarily targeted accessibility needs, with haptics as a substitute for visual feedback, studies using haptics outside of a visualization context have shown value in experiential factors, such as increased confidence in ambiguous contexts and higher engagement. We explore vibrotactile feedback as a reinforcing information channel for communicating trends in details-on-demand tooltips on touchscreens. We identify preferred parameter configurations for our haptic encoding, informed by a study where participants identified parameter configurations that they perceived to most accurately reflect the dynamics of line charts appearing in tooltips. In a second study, we evaluated participant performance in a pairwise comparison task, finding that incorporating vibrotactile encoding improves involvement without affecting accuracy. We discuss the implications of these findings for future visualization design, and propose directions for applications and future studies.
