I had motion sickness for the first ~38 years of my life, and had it cured. Posting here because I went the majority of my life without knowing that such a treatment existed. About a year ago I flew to the University of North Dakota and spent an hour a day over 3 days sitting in a simulator that would spin faster and faster while the facilitator talked to me over the headset and kept me distracted. Was nowhere near a…

Wow That’s amazing, how bad was your motion sickness before you went? This would be life changing for me, I have to take dimenhydrinate when I fly or else I’ll get nauseous to the point of vomiting.

Good point and thanks for the heads up. Mostly asking it as a question, given that graphene runs Google play services (optionally) as a normal, sandboxed service with no special permissions might help a bit, but I guess unless you disable networking for every other service installed, this is sort of impossible to plug 100%? IPC can be quite the security hole.

Only if the other services provide a network proxy right? You'd need to find an exploit in the app otherwise. Edit: although, I just remembered that it's actually as simple as sending "open this URL" intents to the Android equivalent of sensible-browser, which everyone will have installed. That does rely on users not understanding or caring about what's happening or it only works for the first user

Yeah, there are endless holes unfortunately with IPC. It has been hardened by more recent android versions https://developer.android.com/guide/topics/manifest/queries-...

but even something like "share via Chat app" can be used to leak information, e.g. it will have the link preview loaded".

Off topic (but helpfully hopeful to someone!): In the rare cases where I get motion sick I can usually "hack" my way out of it by closing my eyes and imagining myself skiing down a mountain avoiding obstacles in an erratic path that matches the patterns of motion I'm feeling (calculated JIT). Presumably you have to have a lot of experience skiing for this to work, but there are probably isomorphic activities (weaving…

This doesn't work for everyone, for example, if I get motion sick, closing my eyes makes it far worse, almost immediately.

The article mentions this, but it works on Macbooks as well! You can set up a shortcut key (press the fingerprint button 3x) to enable and disable it. I have a work shuttle I take and this makes it so much more tolerable to use my computer on the bus.

What's the setting called? I haven't been able to find it. Is it only on Tahoe or something?

Accessibility -> Motion -> Vehicle Motion Cues.

This is on Tahoe, not sure about earlier versions.

I think what he means is that the iPhone dots seem to move based on vehicle acceleration and deceleration, whereas the android ones use all phone motion. If I move my iPhone around in my hands the dots don't move, but on my android they do (ie are simulating a stable horizon as the phone tilts, immediately). I don't know which is more effective. I thought the iPhone one was broken at first and didn't have the best re…

That's strange, any idea how it could be able to differentiate? My only guess is some sort of processing, like wait and see if it follows the expected acceleration pattern (moderate initial acceleration from the unexpected-to-the-user car motion, followed by a stronger acceleration in the same direction as one's hands push the phone to keep it in the same visual place) but I'd assume such lag is precisely the issue V…

The difference is very simple:

Apple uses the derivative (i.e. rate of change) of acceleration, while all the other (ineffective, in my experience) third-party apps simply use acceleration.

People with motion sickness can deal with speed just fine. While relaxing on an equatorial beach, you’ll have no qualms hurtling around the poles at 1600 km/h.

Acceleration is also perfectly fine for motion sickness. Most people are being pulled towards the centre of the earth at 1.0 G with no complaints whatsoever.

But the significance during motion sickness is the rate of change of the rate of change. That thing where the vehicle slows down, turns a corner, goes over a bump.

This is why Apple’s motion cues actually work, because they use what actually matters for motion sickness.

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 a…

The worst motion sickness that I ever got was from an early VR set, hacked together at someone's home.

With regular motion sickness, the eyes say "you're standing still", while the inner ears say "you're moving".

With VR, it's the other way around.

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…

I have the same issue your mom does. First-person shooters give me motion sickness (which is why I never got past the first level of Wolfenstein back in the day). Maybe the newer FPS games would be better for my brain, but I don’t have much interest in trying.

One of the other key issues (besides FOV which was mentioned) is the size of the virtual space relative to the speed your character moves at. So for example, Half Life 2 has you moving around in a lab building pretty quickly > instant nausea for me. Meanwhile running around outdoors in Skyrim might not bother you at all.

Visual complexity ups the ante. Think of walking through a grocery store with high shelves filled with a variety of products -- this can cause migraine in some people and, to a lesser extent, also affects vertigo. So you may not want to play, say, grocery store simulators (although I have no idea who actually does anyway, why are those things popular!?).

I'm skeptical that this kind of tech can fully counteract serious motion sickness, like many hours or days on a boat. From personal experience, I know that even if you go out onto the deck and look out on the ocean, so that you have a visual reference to the horizon, it doesn't help. You can look out of the window of the car and still get motion sickness; it doesn't only happen to people who are engaged with somethin…

The apps are targeted at a very specific but common use case: being unable to read while in a moving vehicle. It's not going to help you if you're on a sailboat in heavy seas for a day.

I dunno, I was wondering about this .. if maybe there were a projector on the mast or from a cabin-ceiling mounted project, which always gave a local physical reference to the Earth, no matter the condition of the boat on the sea, it might kind of produce the same effect - albeit instead of applying dots to the screen, its dots to the hull. I really wonder if a polka-dot locator would be effective in addressing sea sickness..

Unfortunately, I get car sick just sitting in the back. No need to look at a phone. So I guess I'll have to wait until Apple Glasses to come out.

That's physically impossible.

Yeah, probably could have phrased that better. They are using completely different approaches. Apple seems to be mostly using the accelerometer, to draw dots and visualize inertia. The Android apps are using the gyroscope, to draw a horizon.

Ah, ok. Thanks for the clarification.
