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.

I had a few years (from 9-12, maybe) where I became carsick very easily, otherwise it hasn't been an issue for me*. In that same time period, I was extremely sensitive to the harsh florescent lights in my classroom, and had to read through a coloured plastic sheet and try my best to cover everything in shadow.

Remembering things like that makes you really thankful when they've just went away. Things do sometimes get better through for no clear reason!

* Except "simulation sickness" from certain 3D games like Minecraft.

> And it's why reading in the car gets some people so horribly sick. As a kid, I was told to turn 90° so that the back and forth of my eyes reading were in line with the motion of the car. This was soooo before any kind of electronic devices. Hell, the radio in the car still had the giant push buttons for saving stations.

Those giant “push” buttons, which automatically unpushed the other buttons when one is pushed, are called…. Get ready… radio buttons. Now you know why radio buttons are called that in modern UIs.

In (post)communist countries there is a common name - ISOSTAT switch.

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.

Mine was not that severe. I would get mildly nauseous during normal commercial airplane turbulence, although very nauseous in small planes and the worst nausea of my life after a glider session, very seasick to the point of being debilitated, and then probably a 6 or 7 out of 10 when reading in the car for more than a few minutes.

Definitely worth a shot IMO.

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.

Gets me both ways--can't read in a car, can't play most FP games (shooter or not.)

With FPS I can clearly tell which ones are going to be a problem. Anything where the whole viewport moves at all rapidly is an issue, especially if it is something other than a straight scroll. But I'm fine with pretty much anything where my cursor moves within the viewport, the viewport only scrolling when I reach the limits.

Seems like there's a few android equivalents: https://play.google.com/store/apps/details?id=com.panshen.mo... https://play.google.com/store/apps/details?id=com.urbandroid... And even one that claims to work with sound: https://play.google.com/store/apps/details?id=com.samsung.a1... EDIT: Actually there's an enormous number of apps like this, many released very recently with similar style etc. Weird.

Read the reviews on that first one. They seem to have gone over to the dark side.

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…

It works in a plane, so it’s somehow able to detect the higher rate of speed, maybe by integrating, but I think it does use signals from CarPlay as well.

From an accelerometer's point of view, there is no observable difference between standing "still" (on earth's surface, moving some km/s around its axis, which also moves around the sun, which also moves around the milky way, which...) and being in an airplane. Both feel ~9.8m/s/s acceleration in the same direction because both are in a moving reference frame that stands still with respect to the accelerometer. The 'absolute' speed of the airplane (relative to the ground or air) is not something the accelerometer can measure, so it couldn't not work at 'higher rates of speed'. (If I understood your comment correctly!)

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 a…

Seems unlikely/strange that all these clones would miss this little thing of using the derivative instead of the accelerometer directly so that it 'actually works'

> 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.

That's the same as being pulled towards the earth at 1 gee. Both are acceleration from the accelerometer's point of view. I'm not sure how to convey this well in text, but maybe try installing a sensor reader (e.g. https://f-droid.org/en/packages/de.rwth_aachen.phyphox/) and looking at how the accelerometer values change when you move it in various ways
