Extended Reality (XR) interfaces offer engaging user experiences, but their effective design requires a nuanced understanding of user behavior and preferences. This knowledge is challenging to obtain without the widespread adoption of XR devices. We introduce MineXR, a design mining workflow and data analysis platform for collecting and analyzing personalized XR user interaction and experience data. MineXR enables elicitation of personalized interfaces from participants of a data collection: for any particular context, participants create interface elements using application screenshots from their own smartphone, place them in the environment, and simultaneously preview the resulting XR layout on a headset. Using MineXR, we contribute a dataset of personalized XR interfaces collected from 31 participants, consisting of 695 XR widgets created from 178 unique applications. We provide insights for XR widget functionalities, categories, clusters, UI element types, and placement. Our open-source tools and data support researchers and designers in developing future XR interfaces.

翻译：扩展现实界面提供引人入胜的用户体验，但其有效设计需要深入理解用户行为与偏好。在扩展现实设备尚未广泛普及的情况下，获取此类知识颇具挑战。我们提出MineXR——一个用于收集与分析个性化扩展现实用户交互及体验数据的设计挖掘工作流与数据分析平台。MineXR能够从数据收集的参与者那里提取个性化界面：针对任何特定情境，参与者使用其智能手机中的应用截图创建界面元素，将之置于环境中，并同时在头戴设备上预览由此生成的扩展现实布局。借助MineXR，我们贡献了一个从31名参与者处收集的个性化扩展现实界面数据集，包含来自178个独特应用的695个扩展现实控件。我们提供了关于扩展现实控件功能、类别、聚类、UI元素类型及布局的洞见。我们的开源工具与数据支持研究人员和设计师开发未来的扩展现实界面。
