The combination of virtual reality (VR) with an omnidirectional walking platform (ODWP) may have potential in rehabilitation settings. However, its use, acceptance, safety, and effectiveness are unclear. This preliminary study aims to understand the feasibility, safety, and user experience (including investigating the onset of cybersickness) while walking on the ODWP with fully immersive VR.
Participants engaged with eight immersive VR walking scenarios. The scenarios were created using 360-degree videos and were programmed to run with the ODWP. Safety modifications for the ODWP were made, with the addition of parallel bars. Quantitative feedback on the perceived safety and acceptance of using VR with an ODWP for rehabilitation was collected. Cybersickness was evaluated using the Simulation Symptoms Questionnaire (SSQ).
Thirty-five participants ( = 8 physiotherapists, = 27 healthy adults) were recruited for this study. The mean perceived safety score was 78.9/100 and acceptance was 64.5/100. Seventy-one percent of participants experienced mild to moderate symptoms of cybersickness as reported on the SSQ. The SSQ scores were not correlated to participant age or simulation exposure time.
VR while using ODWP has the potential for rehabilitation, however, more consideration is needed to address acceptance and cybersickness.
虚拟现实（VR）与全向步行平台（ODWP）相结合在康复环境中可能具有潜力。然而，其使用情况、接受度、安全性和有效性尚不清楚。这项初步研究旨在了解在使用完全沉浸式VR在ODWP上行走时的可行性、安全性和用户体验（包括调查晕动病的发作情况）。
参与者参与了八个沉浸式VR步行场景。这些场景使用360度视频创建，并编程与ODWP配合运行。对ODWP进行了安全改进，增加了双杠。收集了关于使用VR与ODWP进行康复的感知安全性和接受度的定量反馈。使用模拟症状问卷（SSQ）评估晕动病。
本研究招募了35名参与者（8名物理治疗师，27名健康成年人）。平均感知安全得分为78.9/100，接受度为64.5/100。如SSQ报告所示，71%的参与者经历了轻度至中度的晕动病症状。SSQ得分与参与者年龄或模拟暴露时间无关。
使用ODWP时的VR具有康复潜力，然而，需要更多考虑来解决接受度和晕动病问题。
