在本文中，我们提出了一种潜在的晕车缓解技术--重定向倾斜，并进行了一项探索性的虚拟现实(VR)研究，以确定在虚拟运动中是否有可能在视觉上诱导头部倾斜。重定向倾斜包括将虚拟环境(VE)旋转到围绕VR头戴式耳机滚动轴的旋转方向，我们假设这可能会导致用户将他们的身体朝同一方向倾斜，并在弯曲的路径中保持平衡。与之前的技术不同，如视野(FOV)限制或静止帧，这种方法可能通过操纵自我中心的自我运动而不是改变VE的视觉特征来潜在地减少晕厥。作为初步探索，我们对30名参与者进行了一项受试者内研究，以评估重定向倾斜对姿势行为的影响。结果表明，虽然旋转的幅度没有我们预期的那么大，但所提出的技术成功地引起了头部倾斜。我们的结论是，需要进一步的研究来了解重定向倾斜的机理、理想参数和应用。
In this paper, we propose a potential cybersickness mitigation technique, redirected tilting, and conduct an exploratory virtual reality (VR) study to determine whether it is possible to visually induce head tilt during virtual locomotion. Redirected tilting involves rotating the virtual environment (VE) towards the turning direction around the VR headset’s roll axis, which we hypothesize could lead users to tilt their bodies in the same direction and maintain balance during curved paths. Unlike previous techniques, like field of view (FOV) restriction or rest frames, this method could potentially reduce cybersickness by manipulating egocentric self-motion rather than modifying visual characteristics of the VE. As an initial exploration, we conducted a within-subjects study with 30 participants to evaluate the effect of redirected tilting on postural behavior. The results showed that the proposed technique was successful in eliciting head tilt, although the magnitude of rotation was not as large as we had expected. We conclude that further investigation is needed to understand the mechanics, ideal parameters, and applications of redirected tilting.
