“…As a result of these postural instabilities, walking in a virtual environment (VE) can lead to gait instability [17]. In addition, Riem et al [18] found that step lengths were significantly affected by VR in comparison to baseline settings (p < .05). In other studies [19], imbalance and gait disturbance in VR have also been reported.…”

<p>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. </p>

“…Therefore, we observed that gait disturbances occurred for all individuals in the absence of vibrotactile feedback, supporting our hypothesis H1. Previous research has shown that VR may produce postural instability, which may result in gait disturbances [17], [18], [19].…”
