论文摘要
这项研究旨在研究虚拟现实（VR）中各种颤振反馈技术对步态（即步行模式）的影响。先前的研究表明，VR使用者的步态障碍是显着的可用性障碍。但是，尚未进行足够的研究来解决这个问题。在我们的研究中，有39名参与者（有流动性障碍：18，没有移动性障碍：21）在现实世界中的环境和相同的活动中执行了定时的步行任务，并具有不同形式的颤振反馈（空间，静态，静态和节奏）。组内结果表明，相对于患有和没有迁移率障碍的人的VR中的NO颤振条件，每种形式的颤振反馈反馈都显着提高了VR的步态性能（P <.001）。此外，与其他纤维骨架条件相比，两个参与者组的空间颤振反馈显着提高了步态性能（P <.001）。这项研究的发现将有助于使有或没有移动性障碍的人更容易进入VR。
This research aims to examine the effects of various vibrotactile feedback techniques on gait (i.e., walking patterns) in virtual reality (VR). Prior studies have demonstrated that gait disturbances in VR users are significant usability barriers. However, adequate research has not been performed to address this problem. In our study, 39 participants (with mobility impairments: 18, without mobility impairments: 21) performed timed walking tasks in a real-world environment and identical activities in a VR environment with different forms of vibrotactile feedback (spatial, static, and rhythmic). Within-group results revealed that each form of vibrotactile feedback improved gait performance in VR significantly (p < .001) relative to the no vibrotactile condition in VR for individuals with and without mobility impairments. Moreover, spatial vibrotactile feedback increased gait performance significantly (p < .001) in both participant groups compared to other vibrotactile conditions. The findings of this research will help to make real walking in VR more accessible for those with and without mobility impairments.
