It is a very interesting application area. Facebook will be flooding with tennis playing data. ;)
Sooner or later, the technology will apply to golf and golf ball will be GPS tracked. You'll never lose a golf ball anymore. ;)
This is great stuff for athletes and enthusiasts as well as professionals. I just can't help but wonder if sports on "technical steroids" can't but take away fair comparisons of athletes' prowess. Worth watching for that at the upcoming Olympics in London: http://bsr.london.edu/blog/post-79/index.html
Fascinating idea!! Truly appreciate the Babolat team that came out with this marvelous idea. Although I think I have a little doubt on the idea of "share" for a professional tennis player. Will the key contenders for the major tournaments be ready to share their performance data with others, especially their opponents? ;-)
This will help the trainers and learners. They can fine tune their skills. Especially on the shots power and the shots type. The net result is more number of professional talent generation and lot of thrill to the viewers.
