Make some art with your phone sensors
tautme.github.ioIn 2024 I made something similar to this for Playdate, with mirroring and dynamic pen width and dithering based on speed of movement. It is fun https://gingerbeardman.itch.io/rorschach
I tried it out on a whim and it was really fun actually.
The only immediate improvement I could think of (which may be is there in the settings) is to change the zero point so I don't have to have the camera pointed at the floor.
Edit: can "zero" by clicking "begin" with phone pointed forward.
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...
2021:
Is there a reliable way to trigger percussion?
tap the side of the phone, it responds to accelerometer sensor.
Tapped very hard, never worked once. Using android on pixel phone.
Same, also on a pixel
does this work on pixel?

Everything works expect the drums
Even just the plain etch-a-sketch using motion sensing is cool enough.
I suppose this might have been done already?
here is the full list, of trying something out with all the sensors. https://tautme.github.io/phone-sensors/
change paint brush size -> whistle
change color -> put finger in front if camera
make drum sound -> tap side of phone
A digital theremin! Very fun.
which reminds me of building breadboard RF sensors (using fixed caps with variable for calibrating parasitic capacitance) and since these are just oscillators you can calibrate a beat frequency (heterodyne mix) in audible range that has the theremin timbre of a squarish sine wave that you can plug straight to a speaker
It seems to make the user dance, would fun to see video of people using it for the first time. haha
it's cool lol
