语音和手势等输入方式允许用户在不持有或触摸物理设备的情况下与计算机交互，从而实现远距离交互。然而，将触觉反馈纳入这种交互仍然是一个悬而未决的问题。在这项工作中，我们探索了为此目的使用空气涡流环。与湍流且快速消散的标准空气射流不同，涡环可以集中移动几米并提供可感知的反馈。在本文中，我们回顾了涡流形成理论，并探索了特定的设计参数，使我们能够生成能够传递触觉反馈的涡流。应用这一理论，我们开发了一个名为 AirWave 的原型系统。我们通过客观测量表明，AirWave 在 2.5 米的距离处可以实现小于 10 厘米的空间分辨率。我们通过用户研究进一步证明，这可以用于将触觉刺激引导到人体的不同区域。
Input modalities such as speech and gesture allow users to interact with computers without holding or touching a physical device, thus enabling at-a-distance interaction. It remains an open problem, however, to incorporate haptic feedback into such interaction. In this work, we explore the use of air vortex rings for this purpose. Unlike standard jets of air, which are turbulent and dissipate quickly, vortex rings can be focused to travel several meters and impart perceptible feedback. In this paper, we review vortex formation theory and explore specific design parameters that allow us to generate vortices capable of imparting haptic feedback. Applying this theory, we developed a prototype system called AirWave. We show through objective meas urements that AirWave can achieve spatial resolution of less than 10 cm at a distance of 2.5 meters. We further demonstrate through a user study that this can be used to direct tactile stimuli to different regions of the human body.
