头戴式显示器（HMD）系统使得有可能在物理和虚拟世界旋转之间引入差异。小的并且希望不被注意的差异对于重定向行走算法可能是有用的，重定向行走算法寻求允许用户探索大的虚拟空间，同时被限制在小的真实的空间。以前的工作已经检查了人们是否可以检测到固定的差异（例如当虚拟世界的旋转速率被放大一个固定值时）。在这项工作中，我们进行了一项实验，参与者在真实的世界中转动360度，并指出虚拟世界的旋转速率在转动过程中是否增加或减少。我们的研究结果表明，旋转增益，瞬间从一个值跳到另一个相比，在360度转弯的过程中缓慢变化的增益之间没有区别。我们还发现，启动增益影响主观平等点。最后，我们的工作表明，可靠的可检测的增益变化的范围是一致的起始增益为1和起始增益为2。
Head-mounted display (HMD) systems make it possible to introduce discrepancies between physical and virtual world rotations. Small and hopefully unnoticed discrepancies can be useful for redirected walking algorithms which seek to allow a user to explore a large virtual space while confined to a small real space. Previous work has examined if people can detect discrepancies which are fixed (such as when the virtual world rotation rate is amplified by a fixed value). In this work, we conducted an experiment where participants turn 360 degrees in the real world and indicate if the virtual world rotation rate increased or decreased over the course of the turn. Our results show no difference between rotational gains which instantaneously jump from one value to another compared to gains which slowly change over the course of a 360 degree turn. We also found that the starting gain influenced the point of subjective equality. Finally, our work indicates that the range of reliably detectable gain changes is consistent for starting gains at 1 and starting gains at 2.
