AI 中文摘要
随着扩展现实（XR）成熟为普适计算平台，2D与3D输入模态间的脱节仍是实现无缝工作流的关键障碍。频繁在用于2D精度的鼠标与用于3D操作的手势间切换，会引发显著的身体疲劳和认知负荷。为解决这一问题，我们提出PlanePivoting，一种多模态交互技术，通过利用注视-鼠标对齐将标准鼠标输入扩展到3D空间。该技术会根据注视与鼠标光标间的空间重叠动态调整平移平面，无需进行物理输入模态的切换。为系统探索注视-鼠标协同的基础设计空间并优化关键变量，我们开展了一项用户研究，在两种平移映射配置文件和两种注视光标孔径下，将PlanePivoting与标准3D Gizmo界面进行对比。结果表明，PlanePivoting在效率指标上优于Gizmo，同时保持相当的精度并产生更高的主观满意度。本研究证明了注视-鼠标对齐在2D与3D环境间实现高效空间操作的潜力。
英文摘要
As XR matures into a ubiquitous computing platform, the disconnect between 2D and 3D input modalities remains a critical barrier to seamless workflow. Frequent transitions between the mouse for 2D precision and hand gestures for 3D manipulation induce significant physical fatigue and cognitive load. To address this, we introduce PlanePivoting, a multimodal interaction technique that extends standard mouse input into 3D space by leveraging gaze-mouse alignment. This technique dynamically modulates the translation plane based on the spatial overlap between the gaze and mouse cursor, eliminating the need for physical input modality switching. To systematically explore the foundational design space of gaze-mouse coordination and optimize key variables, we conducted a user study comparing PlanePivoting with a standard 3D Gizmo interface across two translation mapping profiles and two gaze cursor apertures. Results demonstrate that PlanePivoting outperforms the Gizmo on efficiency metrics while maintaining comparable precision and yielding higher subjective satisfaction. This study demonstrates the potential of gaze-mouse alignment for efficient spatial manipulation between 2D and 3D environments.
