针对虚拟球拍运动，提出了一种非接地、方向力反馈的感知建模和设计方法。使用压缩空气推进喷气机提供定向冲击力，我们反复为三项流行的运动设计，这三项运动的力量范围很大：乒乓球、羽毛球和网球。为了解决非接地力反馈技术的力大小有限的问题，我们进行了一项感知研究，发现了一种新的错觉，即用户感知到的冲击力大小与影响持续时间越长，平均系数为2.57倍。通过一系列形成性、知觉性和用户体验研究，总共72名独特的参与者，我们探索了几种知觉设计，使用力量大小缩放和持续时间缩放方法来扩大知觉力量大小的动态范围。我们的用户体验评估显示，对于不接地的力反馈系统，感知设计可以显著提高真实性和偏好，而不是基于物理的设计。
We present AirRacket, perceptual modeling and design of ungrounded, directional force feedback for virtual racket sports. Using compressed air propulsion jets to provide directional impact forces, we iteratively designed for three popular sports that span a wide range of force magnitudes: ping-pong, badminton, and tennis. To address the limited force magnitude of ungrounded force feedback technologies, we conducted a perception study which discovered the novel illusion that users perceive larger impact force magnitudes with longer impact duration, by an average factor of 2.57x. Through a series of formative, perceptual, and user experience studies with a combined total of 72 unique participants, we explored several perceptual designs using force magnitude scaling and duration scaling methods to expand the dynamic range of perceived force magnitude. Our user experience evaluation showed that perceptual designs can significantly improve realism and preference vs. physics-based designs for ungrounded force feedback systems.
