Hacky but working sensory substitution on my phone.
been hacking away at sensory substitution cause that shit is cool. (Sensory substitution is a change of the characteristics of one sensory modality into stimuli of another sensory modality.) Cool shit and my first experiment is working pretty well and gives some really rich information about the local magnetic fields just using my phones magnetometer, Whether i can understand it all yet is another thing xp
The basic setup runs an app on my phone that takes the axis of my phones magnetometer and converts them into a unique tone within a certain range. This information is passed into a pair of bone induction headphones that communicate that information to you through sound (or vibration on the lower frequencies but that can be kinda hard to feel accurately)
Plus sides: only requires off the shelf bits, no soldering or wiring needed to get it working all that you need to do is install the app. Bone induction headphones provide a really high sensory resolution and could be a way to encode sensors which are more information dense like visual information.
Downsides: Hard to use your phone for phone things while using it for sensory substitution. The only thing worse than my soldering skills is my coding skills and my app is a real horror show that sucks down battery life crazy fast.
