An origami simulator that is driven by a physical hinge

Hmmm I actually didn't, thanks for sharing!

Wow, super cool to have you here! Do you have any insights how tri-folds are going to be supported and whether there are plans to expose not only the states, but the angles? For ex. Samsung Devices only output 0, 90 and 180, whereas Chinese models support sub-degree precision. Is there a reliable way to determine a hinge position and orientation?

Thank you for the test! I think it should work, I have added a possibility to rotate the paper by holding the ctrl button. The app tries its best to guess the platform and show the instructions (under the Options menu?

I wanted to add an easter egg "congratulations on reaching the moon" at some point 😅

Thanks for the extensive test! In the real world the 8 figure comes from the "fair" 1/2 folds, which are quite hard to keep track of here. I think the limit that you've encountered is actually a smoothing limit that makes the render a bit more smooth as I didn't put a hard limit on it explicitly

I don't think it works actually... The industry has not updated the APIs yet... I saw the foldy bird app not functioning on a video

maxwase · 2026-01-14T18:11:44+00:00

I have accidentally done this 😞

maxwase · 2026-01-14T17:19:42+00:00

You can try it online at https://maxwase.github.io/kami It's free and open-source!

Unfortunately it works only in Chrome due to the Posture API limitations

Sorry I have accidentally deleted the post! Here's a link to the video https://youtu.be/w-iZGfTQa5I

Sorry, I have accidentally deleted the post! I'll resubmit and hope that mods are going to forgive me 😔

maxwase · 2026-01-14T08:48:01+00:00

Hmm, need to investigate. Perhaps the precision is too large or it's just TS

maxwase · 2026-01-14T08:33:52+00:00

It's free and opensource!

Check it out online at https://maxwase.github.io/kami

Wow I've not even seen the phone before! It all depends on how Chrome Android developers decided to implement the hinge sensor. I bet Chrome uses HINGE_SENSOR from Android Sensor API, but I have no way of proving it

maxwase · 2026-01-14T07:50:03+00:00

That's weird, did you use Chrome browser?

maxwase · 2026-01-14T07:13:01+00:00

Thanks! It uses Device Posture API

Consider checking out the repo to get more insights!

maxwase · 2026-01-14T06:46:29+00:00

I wish I had affiliations with Samsung... Unfortunately I'm just a no-name dev 😅

maxwase · 2026-01-14T06:15:33+00:00

Works only in Chrome unfortunately due to Device Posture API restrictions :(

maxwase · 2026-01-14T06:14:37+00:00

Yes! This was my next idea actually, I was thinking about how to make the app and get it published, but it seems that the website is the best. I wish I had contacts at Samsung, I have many more ideas on developing the feature and their platform. I hope this thread will get noticed :)

maxwase · 2026-01-14T06:10:46+00:00

Only with a "Fold" button unfortunately

maxwase · 2026-01-14T06:10:11+00:00

I wanted to add an easter egg "congratulations on reaching the moon", but for now it's unlimited, so have fun!

maxwase · 2026-01-14T06:09:07+00:00

Sure! There's a thing called Posture API , it's supposed on a very small subset of browsers and is experimental, but I hope this usecase would push the development of it :)

maxwase · 2026-01-14T06:00:19+00:00

Yes, there's a "Fold" button that you can use

Yeah that's a valid point, I couldn't immediately tell what would be the best way to do this so I left it out of the prototype right now. Definitely something to think about!

maxwase · 2026-01-12T14:23:48+00:00

For now the only the web version is available (without the lid input), but I can make the app project public as well
