You might ask why motion sickness even exists in the first place. Why do nausea and vomiting make sense when your body is in a car or on a boat? Nobody knows for sure, but there's a convincing theory.

Zillions of years ago, we were foragers. We ate what we found. And if we ate something bad, like a poisonous berry, we could die. One of the first symptoms of neurotoxin ingestion is that your eyes lose their tracking ability. And an easy way for your body to detect this is when your eyes and ears (vestibular system) disagree about your body's position and motion in space.

So we presumably evolved a simple rule:

    if (eyes != ears) { vomit(); }

Which gets that bad berry right back out of the system.

This is why these Android and Apple gadgets work: they restore visual cues helping your eyes match what your ears are telling you. It's why looking at the horizon on a boat helps. And it's why reading in the car gets some people so horribly sick.

My partner got some goofy glasses with liquid in them to help him use his phone in the car.

He only had to wear them for a week or two before his motion sickness from cars was completely cured. Now he can just use his phone, without the glasses, in the car whenever he wants

Never knew this feature existed! I’ve gotten this type of motion sickness my whole life, so I’m excited to try it out. It would be nice if it’s effective for me.

I get the same type of nausea described by the author. I can’t read a book or look at a screen for too long without a feeling awful. I can also get it just from sitting in a rear passenger seat, especially if vehicle has poor visibility, and even worse with a bad driver. I have to really focus on looking outside the vehicle at the moving world.

Interestingly, I think there are people that have the opposite type of motion sickness. For example, my mom could never play arcade racing games without getting nauseous. The issue being focusing on a screen with rapidly moving objects and everything else in the peripheral being fixed, versus focusing on a fixed object and everything in the peripheral moving. She never had any issue reading a book in a moving car

As a kid I didn't get carsick at all. I could work on my laptop, read, whatever while my parents drove. As an adult, at some point I started to barely be able to do anything but keep my eyes on the road without feeling bad.

Turned these on recently, and they work bizarrely well...unfortunately. Downside is that I feel like I lost an excuse to avoid devices for a few minutes while traveling.

Seems like there's a few android equivalents:

And even one that claims to work with sound:

EDIT: Actually there's an enormous number of apps like this, many released very recently with similar style etc. Weird.

During long road trips, back before iPhones and the like, my mom would have us pick out a book and buy it for us to read to keep us entertained while driving.

That worked fine for me, I've never gotten carsick, but for my sister could never do that; after reading for not much time, she would start feeling nauseous. Initially I think my parents thought she was exaggerating to get attention, but eventually she puked in the car because of it and they suddenly had no issue believing her.

It eventually led to them buying a cheap TV/VCR combo and a cheap power inverter for the cigarette lighter and using that for road trips, which didn't seem to bother her very much.

Dunno if they work, but these glasses [1] supposedly help with motion sickness as well

I find using something that puts a display right in front of me also works, like Xreal glasses. I'm not super susceptible to car sickness, but it has hit me in the past. However, with a "heads up display", I never even feel the early warning signs.

I can unfortunately report that these dots have not helped me in cars or trains; anything more than a few seconds looking at a screen during a journey will ensure I feel awful until I have an opportunity to sit or lie still for quite a while after. To be fair, even facing backwards on a train usually makes me sick rather rapidly.

I wonder if this could work on computers, not just smartphones/tablets. Presumably so, assuming they have enough motion sensors. Could a third party dev build it, or is it something that only Apple can build?
