Later, I couldn't look at the screen at all, and I felt dizzy and nauseated when I saw the screen! ! I want to vomit! !
Let me first say that I am neither car sick nor sea sick. I have never fainted in 3D games such as Dragon Valley and first-person perspective games such as CS! !
Never thought of it! ! !
The following are the causes and symptoms of 3D vertigo in Baidu Encyclopedia. I think I am all right! ! !
[Etiology]
There are two ways for people to feel their own movement state:
1. Visual
vision can perceive changes in the environment, and feed back the signal of "self moving" to the brain center.
2. The vestibular apparatus of the inner ear The vestibular apparatus
of the inner ear is the balance receptor of the human body, which includes three pairs of semicircular canals and the utricle and balloon of the vestibule. In the semicircular canal, there are ampulla ridge, utricle, balloon, and otolith (also known as cystic plaque), which are all vestibular terminal receptors, which can sense the stimulation of various specific movement states. Stimuli such as shaking and bumping make the hair cells of the vestibular utricle and sacculus produce deformation discharges, which are transmitted and sensed to the center.
If there is a position movement in the real world, the position sensor will also transmit the movement status of the body to the brain at the same time. The feedback of these two aspects to the brain is consistent, and the brain will process the information and use it to control the next movement of the body. But in the virtual world, when playing a 3D game with a relatively high degree of fidelity, the visual perception itself is moving. The information is transmitted to the brain, but the vestibular apparatus of the inner ear does not generate vestibular electrical signals to transmit to the brain, and the information received by the brain is inconsistent, which leads to this disease.
【Clinical manifestations】
It is mostly sudden onset of rotational vertigo. Patients often feel that the surrounding objects rotate around themselves in a certain direction, often accompanied by nausea, vomiting, pale complexion, and cold sweats. In severe cases, blood pressure may drop, deep and slow breathing, and nystagmus. Severe vomiting causes water loss and electrolyte imbalance.
