如果您是第一次听到 Cybersickness这个词，如果您经常使用 PC，请不要担心。 Cybersickness与(Cybersickness)VR Sickness密切相关，简单来说可以将其与现实生活中的Motion Sickness进行比较。(Motion Sickness)您是否经常在乘车时感到头晕或在公共汽车上呕吐？这被称为晕动(Motion)病。这种不平衡导致内耳认为您需要平衡自己，从而导致结果。当您的身体失去平衡时，内耳负责发送反射信号以保护您的身体免受伤害。在这篇文章中，让我们了解一下Cybersickness或VR Sickness. 我们将研究它的定义、原因、症状和治疗方法。
什么是网络病(Cybersickness)或VR 病(VR Sickness)
在玩 VR 游戏时，也会发生同样的事情。大多数 VR 游戏都涉及大量运动、随机跌倒、玩游戏需要采取的动作，让你内心深处觉得你需要平衡你的身体。虽然你的大脑知道你在 VR 中，但当你戴上 VR 耳机时，你的眼睛会认为这是现实，并且会出现同样的晕动病。
网络病(Cybersickness)或VR 病(VR Sickness)的原因
但是，从未感到晕车的人很容易患上Cybersickness或VR Sickness。这有一个合乎逻辑的原因。VR头显使用三种感觉系统——视觉、前庭和本体感受。如果系统是完美的，并且虚拟世界中发生的动作与现实世界中发生的动作相同，那么事情就不会造成问题。但这不会发生。
如果我们的眼睛感知到一个不同步的时刻，即使是几毫秒，身体的反应就会延迟，或者说很匆忙，即身体没有及时做出反应。假设你想从一辆移动的公共汽车上下来，但如果你意识到公共汽车已经在几秒钟后移动了，你就会失去平衡。任何镜头刷新率低的 VR 头戴设备都会出现问题。
购买 VR 耳机时，您需要聪明。以下是您需要检查的常见事项列表：
- 高分辨率显示 VR。
- OLED 显示器优于 LCD 显示器。
- 跟踪器具有亚毫米头部跟踪，以最大限度地减少延迟。
- 每秒帧数 ( FPS ) 应与刷新率匹配以获得最佳体验。
- 使用具有高图形和硬件支持的 PC，因为它会影响帧速率。
网络病的症状
如果你不能长时间玩 VR 游戏并且需要经常休息，你就会患上这种病。很多时候，在游戏中环顾四周时，尤其是在非平坦地形中，您将无法玩像过山车或生病一样简单的游戏。
(Precautions)VR 疾病(VR Sickness)的预防和 治疗(Treatment)
除了选择正确的硬件、VR 耳机、超高速 PC 之外，您还需要采取某些预防措施来帮助您解决此问题。但是，请记住，如果您经常使用错误的硬件，疾病会再次出现。
在 VR 中休息一下：(Take breaks when in VR:) 许多 VR 游戏都有不需要采取任何行动的情况。它可能是一个休息，一个过场动画或任何类似的东西。在这些情况下，您可以闭上眼睛。这样，你的眼睛和你内心的一年就会同步。
保持呼吸： (Keep Breathing: )玩游戏时错过一些呼吸并不是什么大不了的事。我玩了几场激烈的 Xbox游戏(Games)，玩完之后，我会长长地深吸一口气。通常，当你匆忙时，身体会选择浅呼吸，你在 VR 中也需要注意这一点，就像在锻炼中一样。深呼吸在这里很重要。
Sit & Play： 许多 VR 游戏不需要你站着玩。他们所需要的只是手部运动或最小的身体运动。 坐在舒适、安全的椅子上玩这些游戏。(Play)确保(Make)正确选择您的椅子。您不想拿起容易失去平衡的塑料椅子。相反，看看你是否可以坐在沙发上，并确保地板不会受到太大伤害。在 VR 中，您将不了解现实世界。
更改视距或 FOV： (Change View distance or FOV: )不要近距离玩 VR 游戏。保持远处的视野。VR 耳机确实允许您更改此FOV的视距并找到适合您的距离。稍微移动一下，看看你的身体反应是否是积极的，如果没有进一步调整，直到你找到它。
凉爽舒适的环境：(A cool comfortable environment: )在 VR 中玩游戏时，请将其设置在让您感到舒适的地方。空调房是首选，因此当您的身体变高时，外部凉爽的温度可以照顾它。你不想在一个让你流汗和发热的环境中玩耍。
定期休息：(Take regular breaks:) VR 会让人上瘾，就像任何游戏一样，你需要像玩游戏一样定期休息。任何长时间的事情都会从身心中汲取过多的能量。你需要回到现实世界才能找到平衡。在激烈的比赛后稍作休息、暂停游戏、较长时间的休息会有所帮助。
专注一点： (Focus on a point: )玩密集型游戏时，你需要看看这里，那里。这会导致头晕。比如说(Say)，过山车 VR 游戏可以做到这一点。战胜头晕的最好方法是专注于这一点几秒钟甚至一分钟。如果您周围的场景不断变化，也许可以低头看看您的腿或鞋子。这将减少头晕。
让您的身体为 VR 做好准备：(Get your body ready for VR:)如果您是 VR 新手，请不要跳入高强度游戏。慢慢开始(Start)，给你的身体一些时间来适应它。下载(Download)一些对您有帮助的免费 VR 游戏，您的身体就会了解 VR 中发生的事情。你仍然需要遵循我上面所说的一切。
问专家：(Ask the experts:)这几乎适用于生活中的一切，任何生活，无论是虚拟的还是真实的。有一个超级 Reddit 线程(super Reddit thread)，消费者通过在他的视图中添加覆盖来修复他的 VR 疾病。那些不透明/半透明的边界减轻了他的恶心和头痛。更多信息请访问ncbi.nlm.nih.gov。
最后，如果没有任何帮助，请寻求医生(Doctor)。不要(Don)害怕，这主要是在最坏的情况下。您可能需要采取预防措施几天，但一切都会好起来的。

What is Cybersickness or VR Sickness? Symptoms Precautions Treatment
If you аre hearing the term Cybersickness for the first time, don’t be worried if you use PC a lot. Cybersickness closely relates to VR Sickness which in simple words can be compared to Motion Sickness in real life. Have you often felt getting dizzy when traveling in a car or felt vomiting when on a bus? This is called Motion sickness. This imbalance causes the inner ear to think that you need to balance yourself and hence the result. The inner ear is responsible to send a reflex signal to safeguard your body from injury when your body goes out of balance. In this post, let’s learn about Cybersickness or VR Sickness. We will look into its definition, reasons, symptoms, treatments.
What is Cybersickness or VR Sickness
When playing VR games, the same thing happens. Most VR games involve a lot of movement, random falls, actions you need to take to play games, make your inner year feel that you need to balance your body. While your mind knows you are in VR, when wearing VR headsets, your eyes perceive this as reality, and the same kind of motion sickness kicks in.
Reasons for Cybersickness or VR Sickness
However, people who never felt motion sickness can get Cybersickness or VR Sickness quite easily. There is a logical reason for it. VR headset uses three sensory systems–visual, vestibular, and proprioceptive. If the system is perfect, and the actions happening in the virtual world are the same as in the real world, things would not have caused a problem. But that doesn’t happen.
If our eyes perceive a moment which is out of sync, even by a few milliseconds, the response taken by the body is delayed, or rushed i.e. body doesn’t respond timely. Say if you want to get out of a moving bus, but you will be out of balance if you realize that the bus was already moving only a few seconds later. Any VR headset which has a poor refresh rate for its lenses will cause problems.
You need to be smart when buying a VR headset. Here is the list of common things you need to check:
- High-Resolution Display VR.
- OLED displays over LCD displays.
- Trackers have sub-millimeter head tracking to minimize the delay.
- Frames-per-second (FPS) should match the refresh rate for the best experience.
- Use a PC with high graphics and hardware support as it affects framerates.
Symptoms of Cybersickness
If you are not able to play VR games for long and need to take constant breaks, you are suffering from the sickness. Many a time you won’t be able to play the games which are as simple as a roller coaster or sickness feeling while looking around in the game, especially in a non-flat terrain.
Precautions & Treatment for VR Sickness
Apart from choosing the right hardware, both VR headset, a superfast PC, you need to take certain precautions which will help you fix this problem. However, do remember that if you are constantly involved in the wrong hardware, the sickness will show up again.
Take breaks when in VR: Many VR games have situations where you don’t need to take any action. It could be a break, a cutscene or anything similar. You can close your eyes during these scenarios. That way, your eyes, and your inner year will come into sync.
Keep Breathing: It’s not a big deal to miss some breathing when playing a game. I played a few intense Xbox Games, and after finishing, I would take a long deep breath. Usually, the body chooses to take a shallow breath when you are in a rush, and you need to take care of this in VR as well, as you do in a workout. Deep breathing is important here.
Sit & Play: Many VR games don’t need you to stand, and play. All they need is hand movement or minimal body movement. Play those games while sitting in a comfortable, and safe chair. Make sure to choose your chair correctly. You don’t want to pick up a plastic chair which gets out of balance easily. Instead see if you can get on a sofa, and make sure the floor doesn’t hurt much. You will have no idea of the real world when in VR.
Change View distance or FOV: Don’t play the VR games up close. Keep the view at a distance. VR headsets do allow you to change this view distance of FOV and find a distance which is comfortable for you. Move around a bit, and see if your body response is positive, if not further adjust till you find it.
A cool comfortable environment: When gaming in VR, set it up at a place which comforts you. An AC room is preferred so when your body gets high, the external cool temperature can take care of it. You do not want to play in an environment which makes you sweat, and heats you up.
Take regular breaks: VR is addictive, just like any gaming, and you need to take regular breaks just like in gaming. Anything which is pro-longed draws too much energy from body and mind. You need to come back to the real world to find your balance. A small break, pause games, a longer break after an intense session of the game helps.
Focus on a point: When playing intensive games, you need to look here, and there. This causes dizziness. Say, for example, a roller coaster VR game can do that. The best way to beat the dizziness is to focus on the point for a few seconds or even a minute. Maybe look down at your leg or shoes if the scenes are constantly changing around you. This will reduce dizziness.
Get your body ready for VR: If you are new to VR, then don’t jump into a game of high intensity. Start slow, and give your body some time to adjust to it. Download some free VR games which help you, and your body understands what’s going around in VR. You will still need to follow everything I had said above.
Ask the experts: This applies to almost everything in life, any life, virtual or real. There is this super Reddit thread where a consumer fixed his VR sickness by adding overlay in his view. Those opaque/semi-transparent borders reduced his nausea and headache. More on this on ncbi.nlm.nih.gov.
Lastly, if nothing helps, seek a Doctor. Don’t be scared, and it’s mostly in a worst-case scenario. You may have to take precautions for a few days, but things will be alright.
