Ask HN: How to determine body position while sleeping?

1 points by yohann305 ↗ HN
Hello, I need help figuring how to tell in which position someone is sleeping using a camera (and ML i guess?), i.e sleeping on left/right side, back, sleeping on your stomach.

Is there such a ting that already exists?

Any help to point me in the right direction is greatly appreciated, thank you!

I saw a 2 Minute Papers video that talks about the paper [0] I linked below. Basically the AI segments up the human body in to pieces.

Using that data you could create a classifier for either pre-defined postures/positions or let it create its own classes (naive classification, I think?)

Source [1] is a different kind of segmentation.

I think your biggest obstacle will be training sets (assuming you want to use AI/ML). Once you've got training sets, the presence of obstacles (sheets/blankets) might not be so much of an issue.

you can try to use the camera on your computer. Just put it on the right place where can shoot your sleeping bed, open it and turn on the camera to start video shooting.
