Systems and methods for measuring and/or analyzing swing information

1. A method for monitoring a golf swing comprising:

providing a mobile telephone having one or more accelerometers and a program stored therein that when executed by the mobile telephone causes the mobile telephone to:

monitor acceleration of the mobile telephone as the mobile telephone swings;

collect acceleration information based on the monitored acceleration of the mobile telephone as the mobile telephone swings;

analyze the collected acceleration information to determine one or more characteristics of a golf swing based on the collected acceleration information; and

output information regarding the one or more characteristics of the golf swing on a display of the mobile telephone;

coupling the mobile telephone to a golf club; and

generating, by the one or more accelerometers, a corresponding one or more electrical signals as the mobile telephone swings while a user swings the golf club, the one or more electrical signals indicative of an acceleration of the mobile telephone;

executing the program stored in the mobile telephone coupled to the golf club to:

monitor the acceleration of the mobile telephone as the mobile telephone swings while the user swings the golf club to produce acceleration information;

collect the acceleration information as the mobile telephone swings;

analyze the collected acceleration information to determine one or more characteristics of the golf swing based on the collected acceleration information; and

output information regarding the one or more characteristics of the golf swing on the display of the mobile telephone.

2. The method of claim 1 , further comprising executing the program to determine one or more of acceleration of the golf club, velocity of the golf club, and speed of the golf club.

3. The method of claim 1 , further comprising executing the program to determine one or more of ball-club contact, ball-club contact timing and ball-club contact force.

4. The method of claim 1 , further comprising executing the program to determine a number of swings of the golf club.

5. The method of claim 1 , further comprising executing the program to determine one or more of predicted ball travel distance and predicted ball position.

6. The method of claim 1 , further comprising executing the program to detect wirelessly transmitted signals from multiple users.

7. The method of claim 1 , further comprising executing the program to transmit swing information over the Internet.

8. The method of claim 1 , further comprising executing the program to convert acceleration information into an audio signal and provides an audio signal indicative of swing tempo.

9. The method of claim 1 , further comprising executing the program to compare a current swing to an ideal swing and output a cue if the current swing varies from an ideal swing in real time.

10. The method of claim 1 , further comprising:

receiving at least one swing statistic for each one of a group of golfers to provide received swing statistics; and

executing the program to track the received swing statistics.

11. The method of claim 1 , further comprising executing the program to detect wirelessly transmitted signals from multiple users and track swing statistics of a group of golf players.

12. The method of claim 1 , further comprising executing the program to prompt a user to indicate when a swing is a practice swing.

13. The method of claim 1 , further comprising executing the program to prompt a user to indicate when a swing is a practice swing by speaking a command.

14. The method of claim 1 , further comprising executing the program to graph swing information.

15. The method of claim 1 , further comprising executing the program to compare current swing information to historical swing information of a user.

16. The method of claim 1 further comprising executing the program to compare current swing information to historical swing information of a golf pro.

17. The method of claim 1 , further comprising executing the program to compare current swing tempo information of a user to historical swing tempo of the user or a golf pro.

18. The method of claim 1 , further comprising executing the program to compare current swing speed information of a user to historical swing speed of the user or a golf pro.

19. The method of claim 1 , further comprising executing the program to compare current ball-club contact force information of a user to historical ball-club contact force of the user or a golf pro.

20. The method of claim 1 , wherein coupling the mobile telephone to a golf club includes coupling the mobile telephone to a shaft of the golf club.
