Ryan Phillips created a wearable technology system to provide boxers with feedback on their form during workouts. The system uses motion sensors to collect raw data on punches, which is then analyzed using machine learning algorithms to classify different punch types and detect errors. After optimizing the model and validating it with new data, the system achieved 89% accuracy in identifying punches, up from an initial 77% accuracy, by simplifying the user interface and removing noisy data for certain punch types.
