PROJECT CONCEPT

This project will help beginning tennis players learn how to swing and hit a tennis ball in the right spot. This smart tennis racquet will provide tennis players feedback in a friendly, easy-to-understand way in order to allow them to improve on their swing. Ideally this training tool could also be added to any existing racquet during restringing.

We will accomplish this by placing an embedded controller on a tennis racquet that measures that measures the pressure differential between strings during a hit in order to locate the hit and notify the player what part of the racquet was hit.

MOTIVATION

Learning the proper swing to hit the sweet spot of the tennis racquet is very challenging. It is difficult to measure why a hit was good or bad. Our enhanced tennis racquet will make the learning process a little easier for all new tennis players.
