PostureFix is a Python-based application designed to help users maintain good posture while working at their desks. It uses a webcam to monitor posture, alerting users when they slouch or adopt bad posture habits. The program is customizable, allowing users to adjust sensitivity thresholds, alert methods, and more, making it a versatile tool for ergonomic improvement.
I've been struggling with bad desk posture, which has started to affect my comfort and productivity. I made PostureFix to give myself a bit of a push to get better and build healthier habits while working. If you're in the same boat, I hope this tool helps you too!
