AI 中文摘要
虚拟现实（VR）通过在任何地方创建扩展显示屏为生产力工作提供了潜力，但当前系统通常依赖外部输入设备，限制了移动VR的即时使用。我们引入了HandPad，这是一套利用不对称双手协调和自我触觉支持优势的裸手交互技术。HandPad将非优势手（NDH）用于建立空间框架和交互上下文，而优势手（DH）进行细粒度操作。用户可以使用NDH手势作为输入修饰符来更改DH交互的模式和目标，包括多窗口导航、窗口内内容交互和窗口管理。NDH的手掌表面还用作物理触摸表面，为有效的DH触摸交互提供被动触觉反馈。双手及其交互在空间上重新映射到窗口表面，实现与虚拟内容的舒适直接交互。一项探索性研究表明，HandPad实现了高效且符合人体工程学的交互，证明了其作为VR中无设备知识工作方法的潜力。
英文摘要
Virtual Reality (VR) offers potential for productivity work by creating expansive displays anywhere, yet current systems often rely on external input devices that limit the on-the-go use of mobile VR. We introduce HandPad, a suite of bare-hand interaction techniques that leverage the benefits of asymmetric bimanual coordination and self-haptic support. HandPad assigns the non-dominant hand (NDH) to establish spatial frames and interaction contexts, while the dominant hand (DH) performs fine-grained manipulation. Users can use NDH gestures as an input modifier to change the mode and target of DH interactions, including multi-window navigation, in-window content interaction, and window management. The palm surface of the NDH also serves as a physical touch surface, providing passive haptic feedback for effective DH touch interaction. Both hands and their interactions are spatially remapped to the window surface, enabling comfortable and direct interaction with virtual content. An exploratory study showed that HandPad enables efficient and ergonomic interaction, demonstrating its potential as a device-free approach for knowledge work in VR.
