摘要

重定向行走技术可以通过比现实世界行走空间大得多的沉浸式虚拟环境实现自然运动。然而,引导用户的最有效策略仍然是一个悬而未决的问题,因为大多数先前提出的算法只是将用户重定向到物理空间的中心。在这项工作中,我们提出了一个理论框架,该框架计划通过虚拟环境的行走路径,并计算结合平移,旋转和曲率增益的参数,以便用户可以基于效用函数有效地遍历一系列定义的路径点。该函数最大限度地减少了明显的重新定向的数量,以避免引入潜在的中断。这种方法的一个显著优点是,它利用物理和虚拟环境的布局知识来增强转向策略。

An enhanced steering algorithm for redirected walking in virtual environments
Redirected walking techniques enable natural locomotion through immersive virtual environments that are considerably larger than the available real world walking space. However, the most effective strategy for steering the user remains an open question, as most previously presented algorithms simply redirect toward the center of the physical space. In this work, we present a theoretical framework that plans a walking path through a virtual environment and calculates the parameters for combining translation, rotation, and curvature gains such that the user can traverse a series of defined waypoints efficiently based on a utility function. This function minimizes the number of overt reorientations to avoid introducing potential breaks in presence. A notable advantage of this approach is that it leverages knowledge of the layout of both the physical and virtual environments to enhance the steering strategy.
