I don't get car sick looking at a screen in a car, but my daughter very quickly does. Excited to set this up for her to see if it helps her, especially with our annual US Independence Day car trip coming up.

Can this same idea be extrapolated to a device that emits concentrated beams onto the surface of a book?

I'm thinking of those clip-on lights for books that allow one to read in the dark, but for this purpose explicitly. My daughter also gets car sick reading paper books while in a moving vehicle.

Very useful feature for anyone. Probably the lesser known feature because it’s under Accessibility.

It should be a frontline feature to toggle on or off from the command center. It’s there once it’s enabled, but should be there by default.

Is this from a press release? It's a substance-free product endorsement.

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.

Very interesting. I've noticed myself getting mildly car sick now that I'm a little older if I don't take breaks every so often. Does anyone know if there's a similar feature on Android?

Has worked very well for my wife who notably couldn’t look at her phone for even a few seconds without feeling ill

I love stories like these. Lots of accessibility features like these dots are sort of conceptually very simple and potentially quite weird ideas, IMHO, but when they work, they work like magic. I have a big soft spot for things that make it more comfortable or even possible in the first place to operate a device, whether a user is disabled or not.

I gave this feature a try and it didn't work for me. I was curious to see if it was effective, so I asked my wife to drive and I tried to read in the iOS "Books" app with the dots on. I think within 5 or 10 minutes I was feeling pretty sick, and stayed that way for the rest of the drive. Hopefully others have better results. I'll have to stick with audiobooks when in motion.

A relatively simple generic device, mounted on a car's interior ceiling, seems possible: It would project light 'dots' below onto everything the user looks at. Using the car's momentum, the dot movement could be mechanical, though you'd need power for the light.

Not every passenger would want to see the dots; their range could be restricted to the user's seating area or narrower - the user placing objects under the dots as needed. Also, of course the device could be turned on and off.

The dots need brightness and color visible on different surfaces, but those could be easily user-adjusted. Also, I wonder if a grid would work. (Edit: For use with screens, possibly the background reflection of the device, with its grid of lights, would work.)

The real question is, would it work? Does Apple's solution generally work or is the OP just a happy anecdote? Is there more magic to Apple's solution than dots swaying with momentum?

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.

Had no idea this was a thing. Have always gotten car sick anytime I'm not driving. They sold me lol

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

It helps, doesn't completely cure it for me but makes looking at google maps / iMessage more bearable. Not reading essays yet though.

I get really bad motion sickness, I tried reading hacker news in the car with these on when the feature first appeared. It didn't help.

> to reduce or, in my case, even eliminate the motion sickness felt when trying to use an iPhone, iPad, or MacBook inside a moving vehicle.

Does it also help people who get carsick without looking at a screen?

I get carsick in pretty much any modern car, unless I'm the one driving.

Wait can I use it for rollercoasters?

Has anyone made a Linux version of this yet? I think Framework laptops and many thinkpads have accelerometers.

I have this on 24/7. I like them even when I'm not driving.

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.

Do they have a boat version of this?

I get car sick easily but on open water I have to sit and watch the horizon or it's adios cookies.

Oh wow, this is great!
