Tennis Stroke Consistency Analysis Using Miniature Wearable IMU

Abstract

This paper presents research made on the topic of how consistent a tennis player is when hitting a stroke. The analysis is made preliminarily only for the most common tennis stroke, which is forehand. The analysis results can be very useful for the tennis coaches and other experts on the evaluation of a tennis player's current shape and performance stability. For swing movement acquisition a miniature wearable device is used. It is positioned on a player's forearm above the wrist and uses accelerometer and gyroscope to record acceleration and angular velocity in all three axes. A wearable device is a part of the system-in-a-cloud service where complex and more detailed game/performance analyses can be performed.
