不涉及腿的物理运动的虚拟行走系统具有能够在坐着或仰卧时体验的优点。通过结合视觉流和足部有节奏的振动，可以有效地产生虚拟行走的感觉。然而，姿势的影响还没有被完全理解。鉴于此，本研究试图调查的影响，姿势（站立，坐着，仰卧）的虚拟行走体验，利用脚的振动和光流。我们的假设是，即使在坐姿或仰卧位，足部振动的同步也会增强行走的感觉。我们的研究结果表明，同步脚振动产生的感觉，虚拟行走在所有三个姿势，与站立姿势引起最强的虚拟行走的感觉。坐姿和仰卧位之间没有观察到显着差异。这些结果表明，利用脚振动的虚拟行走系统有可能提供一定程度的行走体验，即使对于无法离开他们的床的个人。
The virtual walking systems that do not involve physical movement of the legs has the advantage of being able to be experienced while seated or supine. The sensation of virtual walking can be effectively elicited through the combination of optic flow and rhythmic foot vibrations. However, the effects of posture have yet to be fully understood. In light of this, the present study sought to investigate the effects of posture (standing, sitting, and lying supine) on the virtual walking experience utilizing foot vibrations and optic flow. Our hypothesis posited that the synchronization of foot vibrations would augment the walking sensation even in a seated or supine position. Our findings indicate that synchronized foot vibrations produced the sensation of virtual walking in all three postures, with the standing posture eliciting the strongest virtual walking sensation. No significant differences were observed between the sitting and supine postures. These results suggest that virtual walking systems utilizing foot vibrations have the potential to provide a certain degree of walking experience even for individuals unable to leave their bed.
