I did NOT know the motion sensors on my phone were THIS precise, that’s surprising

There was a project from 15 years ago where you could put an iPhone on a desk and if someone was typing, you could determine the keys being pressed via the accelerometer in the phone.

This is the full "vibe code rabbit hole" I went down, with trying to understand what is possible with the sensors. https://tautme.github.io/phone-sensors/

great idea down this thread, make a guitar tuner that listens with the accelerometer. https://tautme.github.io/phone-sensors/accel-tuner.html

intersting that phones ask for permission to camera and mic, but not always for accelerometer

The motion sensors are also usable to listen to conversations...
