Motion Sensing Data Analysis for Racket Sports

Monday, April 10, 2017

Racketware has launched a motion sensing solution for racket sports, with a small lightweight sensor that clips to the racket and records the match as it is played. It uses analysis of the data to provide full electronic coaching for every match.

Racketware tracks the position and orientation of the racket around the court 500 times a second. This provides information on exactly where the player is on the court, and exactly how they are moving, and – most importantly – where they are hitting the ball.

With this extra information it's able to build artificial intelligence routines to analyze the data and help players improve their play. It does this by detecting the player’s specific faults from a number of typical faults that coaches see in real play. Then tracks their progress and feeds it back to them as they work on improving the faults detected.

Dr Paul Mellor, founder of Racketware said: "Sport sensors today are almost literally “in the dark”, in that they can sense the racket moving but they don’t know where it is in the court or what the player is doing with it.

"Consequently they can only provide some basic stats like shot by shot analysis of racket head speed and a breakdown of forehand and backhand. It’s often the case that the data is often not very accurate as they don’t have a view of the court and what is happening in the match.

"We’ve built our initial product around squash, but it’s very adaptable to all racket sports: tennis, badminton, racquetball and the like. It’s aimed at players who want to improve their game. Some will want to use the product in tandem with a real human coach, but others won’t necessarily want to make the time or financial commitment required to work with a coach, and will use Racketware as an e-coach."
