Systems and methods for measuring and/or analyzing swing information
In a first aspect, a system for monitoring a swing is provided that includes a wireless device adapted to couple to a swinging object and to provide information indicative of a characteristic of the swinging object. The wireless device is a cellular telephone or personal digital assistant (PDA). Numerous other aspects are provided.
1. A method for monitoring a tennis swing comprising:
providing a cellular telephone having one or more accelerometers and a program that allows the cellular telephone to:
monitor acceleration of the cellular telephone as the cellular telephone swings;
collect acceleration information based on the monitored acceleration of the cellular telephone as the cellular telephone swings;
analyze the collected acceleration information to determine one or more characteristics of a tennis swing based on the collected acceleration information; and
output information regarding the one or more characteristics of the tennis swing on a display of the cellular telephone;
coupling the cellular telephone to an arm or wrist of a user; and
employing the cellular telephone coupled to the arm or wrist of the user to:
monitor acceleration of the cellular telephone as the cellular telephone swings while the user swings a tennis racquet;
collect acceleration information based on the monitored acceleration of the cellular telephone as the cellular telephone swings;
analyze the collected acceleration information to determine one or more characteristics of the tennis swing based on the collected acceleration information; and
output information regarding the one or more characteristics of the tennis swing on the display of the cellular telephone.
2. The method of claim 1 wherein the cellular telephone includes a program that determines one or more of acceleration of the tennis racquet, velocity of the tennis racquet, and speed of the tennis racquet.
3. The method of claim 1 wherein the cellular telephone includes a program that determines one or more of ball-racquet contact, ball-racquet contact timing and ball-racquet contact force.
4. The method of claim 1 wherein the cellular telephone includes a program that determines number of swings of the tennis racquet.
5. The method of claim 1 wherein the cellular telephone includes a program that determines one or more of predicted ball travel distance and predicted ball position.
6. The method of claim 1 wherein the cellular telephone includes a program that detects wirelessly transmitted signals from multiple users.
7. The method of claim 1 wherein the cellular telephone includes a program that transmits swing information over the Internet.
8. The method of claim 1 wherein the cellular telephone includes a program that converts acceleration information into an audio signal and provides an audio signal indicative of swing tempo.
9. The method of claim 1 wherein the cellular telephone includes a program that compares a current swing to an ideal swing and outputs a cue if the current swing varies from an ideal swing in real time.
10. The method of claim 1 wherein the cellular telephone includes a program that tracks swing statistics of a group a tennis players.
11. The method of claim 1 wherein the cellular telephone includes a program that detects wirelessly transmitted signals from multiple users and tracks swing statistics of a group of tennis players.
12. The method of claim 1 wherein the cellular telephone includes a program that prompts the user to indicate when a swing is a practice swing.
13. The method of claim 1 wherein the cellular telephone includes a program that prompts the user to indicate when a swing is a practice swing by speaking a command.
14. The method of claim 1 wherein the cellular telephone includes a program that graphs swing information.
15. The method of claim 1 wherein the cellular telephone includes a program that compares current swing information to historical swing information of the user.
16. The method of claim 1 wherein the cellular telephone includes a program that compares current swing information to historical swing information of a tennis pro.
17. The method of claim 1 wherein the cellular telephone includes a program that compares current swing tempo information of the user to historical swing tempo of the user or a tennis pro.
18. The method of claim 1 wherein the cellular telephone includes a program that compares current swing speed information of the user to historical swing speed of the user or a tennis pro.
19. The method of claim 1 wherein the cellular telephone includes a program that compares current ball-racquet contact force information of the user to historical ball-racquet contact force of the user or a tennis pro.
