Inspiration

Wanted to create something practical, helpful to a certain demographic, but with the possibility of being used by all.

What it does

Changes control of cursor from hand to now wrist, larger range of motion, finer control.

How we built it

We used an ESP32-S3 microcontroller and fed it data from a 3 axis accelerometer to output and then wrote a python program to process the serial outputs, which translate to mouse motion.

Challenges we ran into

Someone stole our accelerometer, so we had to borrow a knockoff accelerometer, and spent a lot of time trying to find the proper library that worked with it. Some outside components/circuitry interfered with the output data, certain ESP32 pins had to be off limits.

What we learned

We learned to work together in a way that maximized our strengths, dividing work consisting of both hardware and software components.
