Are you having problems with your golf swing and can't figure out what the problem is? Fujitsu has a mobile-phone application now in development that can help.

ETGA Golf Lesson, which was jointly developed by Fujitsu and another Japanese company, Sensing Control Lab, draws on data from an accelerometer and a compass in the mobile phone to measure and analyze a user's golf swing. The application then tells you whether your swing was good, or whether it needs improvement, assigning a score from 1 to 100 to each swing. It also keeps a running tally of your previous scores, giving you an overall score.

The application also gives you the ability to nail down exactly where in your swing any problems might be. If your swing needs work, the application offers a few tips from a golf coach to improve your technique.

Fujitsu showed off ETGA Golf Lesson at the Ceatec exhibition in Chiba, Japan, giving visitors to the show a chance to try out their swing and measure their results.

The application will be available in handsets that hit the Japanese market near the end of this year.
