On-body menus present a novel interaction paradigm within Virtual Reality (VR) environments by embedding virtual interfaces directly onto the user's body. Unlike traditional screen-based interfaces, on-body menus enable users to interact with virtual options or icons visually attached to their physical form. In this paper, We investigated the impact of the creation process on the effectiveness of on-body menus, comparing first-person, third-person, and mirror perspectives. Our first study ($N$ = 12) revealed that the mirror perspective led to faster creation times and more accurate recall compared to the other two perspectives. To further explore user preferences, we conducted a second study ($N$ = 18) utilizing a VR system with integrated body tracking. By combining distributions of icons from both studies ($N$ = 30), we confirmed significant preferences in on-body menu placement based on icon category (e.g., Social Media icons were consistently placed on forearms). We also discovered associations between categories, such as Leisure and Social Media icons frequently co-occurring. Our findings highlight the importance of the creation process, uncover user preferences for on-body menu organization, and provide insights to guide the development of intuitive and effective on-body interactions within virtual environments.

翻译：体表菜单通过在用户身体上直接嵌入虚拟界面，为虚拟现实（VR）环境提供了一种新颖的交互范式。与传统基于屏幕的界面不同，体表菜单使用户能够与视觉上附着于其身体形态的虚拟选项或图标进行交互。本文研究了创建过程对体表菜单效能的影响，比较了第一人称、第三人称及镜像视角。我们的第一项研究（$N$ = 12）表明，相较于其他两种视角，镜像视角能带来更快的创建速度和更准确的记忆召回。为进一步探究用户偏好，我们开展了第二项研究（$N$ = 18），采用了集成身体追踪的VR系统。通过合并两项研究（$N$ = 30）的图标分布数据，我们证实了基于图标类别（例如，社交媒体图标被一致地放置于前臂）的体表菜单布局存在显著偏好。我们还发现了不同类别之间的关联性，例如休闲类与社交媒体类图标常同时出现。本研究结果强调了创建过程的重要性，揭示了用户对体表菜单组织的偏好，并为指导虚拟环境中直观高效的体表交互设计提供了见解。
