交互在视觉网络探索期间起着至关重要的作用，因为用户需要参与视图中的两个元素（例如，节点，链路）和接口控制（例如，滑块、菜单）。特别是随着网络的大小和复杂性的增长，支持多模态输入的交互式显示器（例如，触摸、语音、笔、凝视）表现出在视觉网络探索和分析期间促进流体交互的潜力。虽然多模态交互与网络可视化似乎是一个很有前途的想法，但仍然存在许多悬而未决的问题。例如，用户是否真的更喜欢多模态输入而不是单峰输入，如果是，为什么？它是否使他们能够更自然地交互，或者多种输入模式是否使用户感到困惑？为了回答这些问题，我们进行了一个定性的用户研究的背景下，网络可视化工具，比较语音和触摸为基础的单峰界面，多模式界面相结合的两个。我们的研究结果证实，参与者强烈喜欢多模态输入超过单峰输入归因于他们的偏好：1）的表达自由，2）语音和触摸的互补性，和3）集成的互动提供的两种模式的组合。我们还描述了互动模式的参与者进行常见的网络可视化操作，并强调未来的多模态网络可视化系统考虑的主题。
Interaction plays a vital role during visual network exploration as users need to engage with both elements in the view (e.g., nodes, links) and interface controls (e.g., sliders, dropdown menus). Particularly as the size and complexity of a network grow, interactive displays supporting multimodal input (e.g., touch, speech, pen, gaze) exhibit the potential to facilitate fluid interaction during visual network exploration and analysis. While multimodal interaction with network visualization seems like a promising idea, many open questions remain. For instance, do users actually prefer multimodal input over unimodal input, and if so, why? Does it enable them to interact more naturally, or does having multiple modes of input confuse users? To answer such questions, we conducted a qualitative user study in the context of a network visualization tool, comparing speech- and touch-based unimodal interfaces to a multimodal interface combining the two. Our results confirm that participants strongly prefer multimodal input over unimodal input attributing their preference to: 1) the freedom of expression, 2) the complementary nature of speech and touch, and 3) integrated interactions afforded by the combination of the two modalities. We also describe the interaction patterns participants employed to perform common network visualization operations and highlight themes for future multimodal network visualization systems to consider.
