关于跨设备交互的 HCI 研究的很大一部分是由用户跨多个移动设备无缝地执行复杂的知识工作的愿景驱动的。这是基于 Weiserian 假设，即如果有可用的“垫”，人们将倾向于将他们的工作分配到多个“垫”上。我们观察到，即使设备非常丰富，这也不是今天的现实。我们提出了一项研究，有 24 名参与者分为 12 组，使用最多 6 台平板电脑完成协作可视化任务。他们可以选择三种不同的可视化类型来回答有关经济数据的问题。任务旨在支持同时使用平板电脑，无论是具有链接视图还是独立视图。我们发现每个用户通常只使用一台平板电脑。定量和定性分析揭示了一种“传统偏见”，它为使用更多平板电脑带来了障碍，并降低了多设备可视化的整体效益。
A sizable part of HCI research on cross-device interaction is driven by the vision of users conducting complex knowledge work seamlessly across multiple mobile devices. This is based on the Weiserian assumption that people will be inclined to distribute their work across multiple ``pads' if such are available. We observed that this is not the reality today, even when devices were in abundance. We present a study with 24 participants in 12 dyads completing a collaborative visualization task with up to six tablets. They could choose between three different visualization types to answer questions about economic data. Tasks were designed to afford simultaneous use of tablets, either with linked or independent views. We found that users typically utilized only one tablet per user. A quantitative and qualitative analysis revealed a ``legacy bias' that introduced barriers for using more tablets and reduced the overall benefit of multi-device visualization.
