基于脚的手势最近作为一种替代交互机制而受到关注，该机制可用于手部忙于或无法使用的情况。本文研究了现实世界中合适的脚部手势映射，以调用命令并与虚拟工作空间交互。我们的第一项研究确定了用户将常见移动设备命令映射到手势的偏好。我们根据离散和连续命令输入来区分这些手势。虽然基于脚的离散输入需要控制的参数相对较少，但连续输入需要仔细设计考虑如何将用户的输入映射到控制参数（例如媒体播放器的音量旋钮）。我们通过三项用户研究进一步调查这个问题。我们的结果表明，与基于位移的交互相比，基于速率的技术明显更快、更准确，并且目标交叉次数要少得多。我们讨论这些发现并确定设计建议。
Foot-based gestures have recently received attention as an alternative interaction mechanism in situations where the hands are pre-occupied or unavailable. This paper investigates suitable real-world mappings of foot gestures to invoke commands and interact with virtual workspaces. Our first study identified user preferences for mapping common mobile-device commands to gestures. We distinguish these gestures in terms of discrete and continuous command input. While discrete foot-based input has relatively few parameters to control, continuous input requires careful design considerations on how the user's input can be mapped to a control parameter (e.g. the volume knob of the media player). We investigate this issue further through three user-studies. Our results show that rate-based techniques are significantly faster, more accurate and result if far fewer target crossings compared to displacement-based interaction. We discuss these findings and identify design recommendations.
