概括

长时间的虚拟现实 (VR) 光流显著影响站立平衡,更高的速度和频率导致更大的响应. 尽管在延长VR暴露期间感到疲劳,但保持了平衡稳定性.

科学领域:

神经科学是一个神经科学.
生物力学生物力学
人类因素工程人类因素工程

背景情况:

短期虚拟现实 (VR) 光流对平衡的影响是已知的,但长期暴露的影响还没有得到充分研究.
了解姿势控制中的感官集成对于VR应用至关重要.

研究的目的:

为了研究长时间VR光流暴露对立式平衡的影响.
为了确定光流参数 (速度,频率) 如何影响平衡响应.
评估在延长VR沉浸期间习惯光流的潜力.

主要方法:

20名健康成年人接受了长时间的VR光流暴露,速度和频率各不相同.
使用力板测量平衡,分析前后压力中心 (CoP) 速度 (AP-Vel) 和平均功率频率 (MPF).
在90秒的试验和总40-60分钟的实验中评估了习惯性.

主要成果:

与非VR条件相比,VR光流显著增加了AP-Vel和MPF (P < 0.0001).
更高的光流速度和频率导致更大的平衡响应 (P <0.05).
在长期暴露期间没有观察到对光流的习惯 (P > 0.2110),尽管报告了疲劳.

Equilibrium and Balance

Equilibrium and Balance

The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

The Vestibular System

The Vestibular System

The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.
