Why virtual reality makes a lot of us sick, and what we can do about it.
Posted this reply in another instance, but several years ago researchers found that adding a virtual nose dramatically decreased motion sickness. However, I haven’t seen any developers adding one in games. I wonder if it’d help.
When the camera movies without me physically moving, I am throwing up immediately. Do you mean a virtual nose would fix that?
Potentially, yeah. Here’s an article I found talking about the research: https://www.purdue.edu/newsroom/releases/2015/Q1/virtual-nose-may-reduce-simulator-sickness-in-video-games.html
Ok that sounds interesting. I just though that glasses wearer might not have motion sickness as often due to the glasses being similar to the VR(or keeping the glasses under the Headset
I wear glasses (which I keep inside the helmet) and have mild motion sickness when moving in VR. The faster I move in-game, the worse it gets. Racing games are OK because I don’t move inside the car, I suspect having a static dashboard is similar to a virtual nose.
Glasses wearer here, I still see my nose with the glasses on. VR gives me mild motion sickness but only when moving around in a “smooth” way (Teleporting or walking irl is fine but using regular controller movement makes me want to throw up after ~30 minutes)
Findings showed the virtual nose allowed people using the Tuscany villa simulation to play an average of 94.2 seconds longer without feeling sick, while those playing the roller coaster game played an average of 2.2 seconds longer.
Yeah instead of throwing up immediately, you won’t throw up until 2.2 seconds in. Problem solved!
The “Tuscany Villa” is an ancient demo that I tried in the Oculus DK1 in like 2014 or so, and it made me sick for hours. It uses very fast continuous movement instead of teleport, and it has a set of stairs that will make you instantly throw up if you try to climb them.
It’s is perfectly possible to create VR experiences that will not make anyone nauseous, Moss being a good example.
So you are saying that 90s is a remarkable improvement?
I would expect a huge difference in the usefulness of a simulated nose, depending on the content. In a roller coaster the movement of your head (rotation) and the movement of the carriage (translation) are separate and clearly defined this way. You control the Rotation while the game controls the translation. I don’t know what this villa demo is, but depending on how the movement is controlled, an unintuitive and unnatural system is bound to make almost everyone nauseous.
Any app that moves the camera (or thw whole world) without user input will make people sick, it’s just a law of good VR. Any app that doesn’t render at a stable 72fps+ will make people sick. Any app that simulates things that make people sick in real life, will also make people sick in VR.
On the other hand, any app that keeps a stable 90fps, that uses teleport with a very short fade instead of thumbstick movement, and that never messes with the camera position, will not make people sick.
Most people who have tried VR and have felt sick, were basically victims of awful, non-optimized VR experiences, and awful VR hardware like Google Cardboard and variants.
What about those, um, VR videos you can find online? I think 94 seconds is all I really need.
I don’t think you want a nose for those videos.

Eagle Flight uses it, but it is a beak instead of a nose.
40-70% and 80% for women sounds insanely high. I got a used HTC Vive to have beat saber parties with people and so far none out of about 20 people have experienced nausea even with heavy drinking.
I tried a vr headset at a convention where they had it just giving you a virtual tour of a farm to show off what the headset could do.
I had to take it off in less than 30 seconds because it was giving me a migraine and making me feel sick.
HTC, Valve, and Oculus (well before the Facebook buyout) established very early on that frame rates of 90 fps or higher with a response time of <1 ms were critical factors for preventing motion sickness. Meta either hasn’t gotten the memo or just doesn’t care.
Even with well-established VR legs, I start feeling unpleasant if my FPS starts dropping below 75 for extended periods of time.
Aside from that, it’s also down to game development. I’ve been seeing newer, inexperienced VR developers creating scenes that don’t take into consideration how our brains perceive motion; and they end up creating some nausea-inducing scenes or game mechanics, in addition to doing things like shoving your head onto the floor or through an object. The easiest example is pressing into a wall or table, and the colliders shove your head and body back when you’re not expecting it.
As much as I want VR to be awesome, I’ve had motion sickness from playing Portal while sitting at a desk. Consequently, I think this is just one of those technologies that I have to be happy for other people to enjoy.
Just FYI, I can’t play FPS games without puking, but VR games work for me. The fact that my inner ear matches what I’m seeing in the game makes the difference.
Huh, suppose I’ll have to give it more of a chance. Which VR games have you particularly enjoyed?
Beatsaber obviously, alyx, in death unchained, superhot. Some of the notable ones I can think of offhand. There’s a pretty wide variety of genres though, so depending on if you like action, puzzlers, etc is going to matter a lot. It’s also been a year since I’ve played due to lack of space.
I couldn’t play portal 2 either (never tried 1). Made me sad knowing how awesome it’s supposed to be.
I managed to make it through both in a weekend or so, but it was rough.
I went on a a VR rollercoaster with my new girlfriend (asian) at a amusement park where they move the cart according to the movement in VR.
She was totally OK, and I was totally wet of sweat, down to my underwear. I really almost puked.
But I have that problem even on a bus and in a car as a passenger (so I basically always drive if possible). Big ships, trains and airplanes are totally ok.
When I was about 9 I had to puke on the bus and my dad didn’t want to have to clean the buss so he let me puke into the pocket of his jacket 🤪
What does your gf being Asian have anything to do with this?
Because the article said that women have a higher chance to feel sick and Asian people have also a higher chance, and she is the combination of being a woman and being Asian, and despite that not having any problems. I thought it was noteworthy.

First person shooters already make some people feel nauseous. It’s the disconnect between your vision telling you that you’re moving while everything else, especially your balance centers, saying you’re not.
VR kinda makes it even worse if you’re not on some 2D treadmill
I am a victim of this. It sucks.
So not a problem at all?
Ikr? Lmao
I’m young and have played computer games since childhood, I never bought a VR headset cause anything more than 20 minutes and I feel dizzy as fuck.
VR needs an overhaul for me to actually buy into it, I honestly just think the headsets aren’t going to work, I don’t think a higher refresh rate will fix this
I’m not sold on the gaming side of it but I loved my quest for movies. I’m planning to buy another one one day and it’s something that I’ll consider essential for old age retirement.
Today l learned that some people get motion sickness from playing flatscreen games. How do you even survive a car? Let alone an airplane?
Being in a car or aeroplane is totally different from playing a game, VR or otherwise. The motion sickness is a result of a mismatch between the sense of your own motion from what you are seeing, and the sense of your own motion from your inner-ear (which is basically an accelerometer).
In a car or an aeroplane, as long as you are looking at the window then there is no problem. (But often people get car-sick if they try to read a book or something, because then they can’t see the motion - they can only feel it.) But in a game, you can see the motion but not feel it - so that can also give motion sickness.
Many modern first-person games have an option for ‘mouse smoothing’ (or something similar), and that generally help reduce or eliminate motion sickness.
The problem is in a car, your body is actually moving and your sense of movement aligns with what your eyes are seeing. I’m not an expert but there’s something about fluid in your ears moving?
When it comes to gaming on a flat screen, your eyes are interpreting movement but you are not moving. This, from my understanding is what causes the motion sickness.
I can’t use these VR headsets because they make me sick and give me migraines. I’m just fine playing on a TV or monitor though.
I would get so incredibly sick when playing the original wolfenstein and Doom. But I could play halo for hours. Really weird
Some people don’t. That’s why air sickness bags exist.
I only play standing games that stick within the confines of room scale, that way all my movements are natural.
When I play other games, it’s teleport or nothing, no other locomotion form works for my, my sense of balance is to sensitive, and I haven’t had the time to work to get used to it… and swinging on vines is way out no.
Curiously I also get severe motion sickness when I drive go karts, but not when I drive cars. Although, sitting in the passenger seat, especially the rear seats, however can be a problem sometimes if I’m going around windy roads)
I’m super glad I’m not one of them… I will baselessly credit the Nintendo 3DS with developing that skill
“… and that’s a huge problem for the companies behind it.”
Thank you for clarifying.
They could market it to anorexic people and make a profit. Puking while having fun.
Sorry, I’ll let myself out.
its an issue of refresh rate tbh.
I went from vr at 90fps/90hz to 144fps/144hz and i went from motion sick to acceptable.
The frame rate doesn’t matter if I start moving with a controller while I am sitting down IRL. I don’t get the motion sickness if I have to actually walk to move in the game, but the disconnect between moving in the game not matching the movement of my body is what really causes motion sickness for me.
But that’s something you can get used to, I fly FPV drones and that feeling was overwhelming in the beginning (way more intense than any VR I tried), but if you keep at it eventually you get used it.
I kept at it for 5 years; I never got rid of that kind of nausea. Only the nausea induced by the visual effect which I had even just playing, like, Work Simulator, at first.
For me it’s the way the motion trackers map head movements, somewhat depends on how it’s implemented in the game, but there’s a way I can move my head that will give me instant nausea in any VR game. I’m not predisposed to motion sickness either, fine on rollercoasters etc.
The Fresnel lenses give me eye fatigue.
I used to get sick but it goes away with time.
I’m in the other camp. The first time I squeezed my 155m spaceship through the tiny mouth of a rotating space station in VR, I wept like a baby. (An Anaconda in Elite: Dangerous)
