18-549: Team BrightGoal

BrightGoal is a real time foot tracking system meant to help athletes (or anyone) improve footwork. The system consists of a hardware module strapped to the users foot, a laptop which is wirelessly connected to the foot module, and a whole host of software on both the computer and the foot module to handle data collection, streaming, and computation.

Technology in sports is an ever growing field which is aimed at improving player performace and safety by employing the vasts amount of data technology can provide us about a player in the game. Using real time motion and orientation tracking of a player's feet, we aim to create a system which can help players see what their feet are doing on the field and suggest areas of improvement to help the players increase their performance as well as minimize chances for injury.
