From On-Court Battles to Social and Memorable Learning. Zennis will revolutionize the amateur tennis playing experience. We provide an affordable solution for tracking and recording the movement of the ball and the players during a tennis match, which enables us to gather a huge amount of interesting match data and statistics. The data is uploaded to a social media platform, where players can analyze their performance in detail to follow their development and identify areas they need to work on in their game. They can also share the data with their fellow players and friends in an online sports community. Our solution also functions as an automatic referee and score keeper during the match.
