Granit team is working with Ericsson company and M2S Lab (Moves, Sports, Health) on a connected tennis project. The aim is to design a mobile and low cost wireless system able to provide to the player or his staff, in real time, many useful information such as localization on the court and analysis of his different shots. A demo was organized on April 16th during the final week-end of Aziza Open and Ericsson Trophee. Please find it at http://www.trophee-ericsson.com/events/
