A similar thing happened to a friend who was over for game night. We were playing the Monopoly Deal card game when he put a brown and a red card next to each other with kind of a confused silence. Look at this:

(Pictured: Three red property cards next to two brown property cards.) They use only color to indicate property group. I was surprised that such a recognizable brand would allow this to get through. About one in twelve men cannot play this game without assistance.

Seems pretty straightforward.

1. Be a developer and you (or a spouse/child/friend) get motion sickness when looking at the phone while travelling.

2. We’ve known the mechanisms of motion sickness (looking at something static while your inner ear indicates you’re moving) from before smartphones were a thing.

3. We already have a ton of information on the phone to know when we’re in a vehicle, how fast we’re moving, direction, so on.

4. Try adding something to the static screen so it moves in tandem with you and thus reduce the cause of motion sickness.

5. Get the people who get sick to try it out.

If anything, I’m surprised it took a decade and a half to come up with it.

Motion sickness person here. iPhone’s stock one doesn’t work for me. Haven’t tried that on Android. Will see if something similar is available on iOS as third party app.

I use KineStop and it works better than Apple's version on iOS did for me. Hopefully AOSP implements one because you do have to give KineStop rather invasive permissions.

Eventually I will try the open source offerings.

Worth checking first whether your phone already has this natively. My one year old Android by Honor has it built in and exposed in the quick settings (sliding the right down). I know a couple others also have it, but not all of them as discoverable

Very cool that apple made it

I wonder if any other laptops have IMUs that can be used to implement this on Linux/Windows

It works great on Macbook. I don't know why they don't suggest it to folks when car or train movement is detected! I have a feeling a lot of people don't know it exists.

I wish my Pixel 9 had it but I guess it hasn't trickled down yet. I think it's in the latest Android on latest Pixel devices though.

I tried this and it did nothing for me. For a start, the white dots disappear on a white background, so not a good start. The main thing, though, is while it picked up on the vehicle turning it didn't pick up on acceleration much, which is what actually gives me motion sickness.

Honor phones have this in the quick settings (the thing that opens when you slide the right side of the top bar down), labeled "Motion Sickness". Felt well-explained and discoverable.

But the beauty and pain of Android is every brand having slightly different UI. This might well be a manufacturer-specific feature. Or maybe it's a common Android thing that some brands just expose better than others

I think two accelerometers would do it at different ends of the phone. Normal hand-based motion will rarely include a sustained exact acceleration in one direction on both of these at the same time e.

I always assumed this is triggered by Bluetooth connection to the car?

Were a lot of people rawdogging their Thinkpads while driving back in the day? Plugged into an inverter into the cigarette lighter to trickle charge? :-)

It absolutely is working on a ship. At least for me it helps e.g. when traveling on a big ferry etc. but I guess everybody has a different level of tolerance.

Not technically "Accessibility" but Android has a "developer" setting called "Show Touches" which puts little dots on screen when you touch it.

I find it acts a little like being able to see the cursor on a desktop or laptop; it provides a little bit of immediate feedback that the system recognized your intent, and helps make it clear whether it's the OS or just the app when things are getting laggy.

Under "Display & Text Size": "on/off labels" and "increase contrast". "Reduce transparency" is a bit of a mixed bag but is worth trying out.

Under "Audio & Visual", "background sounds" is a built-in 'white noise' generator and can be useful for relaxing / sleeping. You wouldn't want to leave it on all the time, of course.

Under "Touch": "Back Touch" lets you map a double/triple tap on the back of the phone to various actions.

There's a lot of other neat features in iOS Accessibility (eye-tracking control! automatic captions! sound recognition!) and I'd encourage you to poke around to see what's available.

I use the magnifier on iOS to examine small electronics on a PCB, or other small detailed things.

Similarly, on MacOS I use the Zoom feature (Command Key + mouse scroll) to pixel peep when doing graphical work.

Bit of a niche, but I use inverted colors and the camera app to find ticks on my dog. Enabled by triple-clicking the lock button under Settings -> Accessibility -> Accessibility Shortcut -> Classic invert

What do you mean useful to everyone?

Do you think everyone gets motion sickness?

On Android I use super dim, as someone who enjoys low light situations, even the darkest brightness setting can be too bright sometimes

It did for me, but n=1.
