Abstract

Background

The redirected jumping (RDJ) technique is a new locomotion method that saves physical tracking area and enhances the body movement experience of users in virtual reality. In a previous study, the range of imperceptible manipulation gains in RDJ was discussed in an empty virtual environment (VE).

Methods

In this study, we conducted three tasks to investigate the influence of alley width on the detection threshold of jump redirection in a VE.

Results

The results demonstrated that the imperceptible distance gain range in RDJ was not associated with the width of the alleys. The imperceptible height and rotation gain ranges in RDJ are related to the width of the alleys.

Conclusions

We preliminarily summarized the relationship between the occlusion distance and manipulation range of the three gains in a complex environment. Simultaneously, the guiding principle for choosing three gains in RDJ according to the occlusion distance in a complex environment is provided.

在有小巷的虚拟场景中重定向跳跃

在虚拟现实中，重定向跳跃(RDJ)技术是一种节省物理跟踪面积，增强用户身体运动体验的新型运动方法。在之前的一项研究中，在一个空的虚拟环境(VE)中讨论了RDJ中难以察觉的操作增益的范围。方法本研究通过三个实验研究了通道宽度对VE中跳转重定向检测阈值的影响。结果RDJ的不易察觉距离增益范围与小巷宽度无关。RDJ的不易察觉高度和旋转增益范围与巷道宽度有关。结论初步总结了复杂环境下三种增益的遮挡距离与操作范围的关系。同时，给出了在复杂环境下根据遮挡距离选择RDJ中三个增益的指导原则。
