概括
虚拟现实 (VR) 视觉运动会改变姿势摇摆,但只有当个人专注于自我运动感知时. 与视野运动相比,参与者需要显著更大的VR刺激来感知自我运动.
科学领域:
- 人类的姿势控制
- 虚拟现实 (VR) 感官集成 虚拟现实 (VR) 感官集成
- 感知和运动感知和运动.
背景情况:
- 视野运动影响着姿势摇摆和自我运动感知.
- 在VR中,对自我运动的相对感知灵敏度与视觉场运动的相对感知灵敏度尚不清楚.
- 缺乏同时量化摇摆感知和实际摇摆的方法.
研究的目的:
- 为了研究相对感知灵敏度的自我运动对比视觉场运动在VR.
- 为了确定可观察到的姿势摆动是否根据感知任务 (自动运动与视野运动) 不同.
- 开发方法来量化摇摆感知与摇摆测量一起.
主要方法:
- 健康的成年人站在虚拟现实环境中,经历了虚拟的阴影形旋转.
- 参与者执行了不同的任务:检测房间运动或增加姿势摇摆.
- 追踪了头部摇摆,并使用心理测量曲线分析了运动感知反应.
主要成果:
- 对房间运动的感知需要明显较低的刺激幅度 (0.42°),而不是对姿势摇摆 (2.02°) 的感知.
- 视觉刺激期间和之后头部摇摆显著增加,但只有当参与者感知到增加的姿势摇摆时.
- 要感知自我运动变化与视野运动变化相比,需要近5倍的VR刺激幅度.
结论:
- 对视野运动的感知灵敏度高于VR中的自我运动.
- 可观察到的姿势摇摆是由VR视觉运动调节的,但这种效果取决于内部对自我运动的关注.
- 在VR运动中头部摇摆与只有当专注于自我运动,而不是外部视觉线索时才与感知有关.

Major Somatic Sensory Pathways
1.3K
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...

Equilibrium and Balance
5.1K
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...

Factors Affecting Perception
1.9K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.

The Vestibular System
40.2K
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.

Indirect Motor Pathways
1.7K
The indirect motor or extrapyramidal pathways originate in the brainstem, the lower portion of the brain that connects it to the spinal cord. They consist of several distinct tracts, each with specialized functions. The four main tracts of the indirect motor pathways are the vestibulospinal tract, the reticulospinal tract, the tectospinal tract, and the rubrospinal tract.
The vestibulospinal tract originates in the vestibular nuclei of the brainstem. The vestibular system detects changes in...

Auditory Perception
587
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...
