沉浸式虚拟现实中的传统3D用户界面（3DUI）在涉及规模、视角、参考框架和维度多样性的任务中可能效率低下。本文提出了一种基于平板电脑和hmd的协调式混合虚拟环境系统的解决方案。佩戴非遮挡式头戴式头戴设备，用户可以观看并与安装在非主前臂上的平板电脑进行交互，该平板电脑提供了多点触摸交互界面，以及虚拟世界的外心上帝视图。为了减少3D交互任务和界面之间的过渡差距，提出了四种协调机制，其中两种已经实现，另一种在具有复杂关卡编辑任务的用户研究中进行了评估。基于主观评分、任务表现、访谈反馈和视频分析，我们发现，尽管学习和使用混合系统很复杂，但具有互补优势的多个交互上下文（ic）可以带来良好的性能和用户体验。结果还建议在IC之间保持3DUI任务同步，因为这可以帮助用户理解它们之间的关系，平滑任务内部和任务之间的IC转换，并激发更多创造性地使用不同的接口。
Traditional 3D User Interfaces (3DUI) in immersive virtual reality can be inefficient in tasks that involve diversities in scale, perspective, reference frame, and dimension. This paper proposes a solution to this problem using a coordinated, tablet- and HMD-based, hybrid virtual environment system. Wearing a non-occlusive HMD, the user is able to view and interact with a tablet mounted on the non-dominant forearm, which provides a multi-touch interaction surface, as well as an exocentric God view of the virtual world. To reduce transition gaps across 3D interaction tasks and interfaces, four coordination mechanisms are proposed, two of which were implemented, and one was evaluated in a user study featuring complex level-editing tasks. Based on subjective ratings, task performance, interview feedback, and video analysis, we found that having multiple Interaction Contexts (ICs) with complementary benefits can lead to good performance and user experience, despite the complexity of learning and using the hybrid system. The results also suggest keeping 3DUI tasks synchronized across the ICs, as this can help users understand their relationships, smoothen within- and between-task IC transitions, and inspire more creative use of different interfaces.
