Abstract

Sensors capable of sensing the proximity of a golf club head and of generating a sensor signal in response thereto are provided. The sensors include control sensors used to communicate user commands and club-head data sensors used to analyze a golf club swing. A computer program is provided to direct a computer to analyze signals generated by the control sensors to interpret commands from a training system user. The computer also analyzes signals generated by club-head data sensors to determine the path, height, impact speed, and face impact angle of the golf club head as a function of the user commands. Analyzed club-head data sensor signals are used to calculate and graphically represent the resulting flight path of the struck golf ball with respect to a graphically simulated fairway and green presented on a video display unit. The simulated fairway and green are defined by data stored within the data storage device. The computer determines faults in the club swing, and outputs to the video display unit and a speaker appropriate recorded audio-visual responses that contain appropriate advice and demonstrations by a well-known golf professional for correcting the faults. A user can also play a simulated golf game on a simulated golf course. A calibrator is also provided to compensate for sensor misalignment.

Claims

1. A computer-based, interactive sports training system, comprising:

a plurality of sensors, each sensor being capable of sensing the proximity of a golf club head and of generating a sensor signal in response thereto wherein the sensors include a sensor for identifying a club selected by a user;

a multiplexer connected to the sensors to format sensor signals received therefrom for communication to a computer; and

a computer program for directing the computer to analyze, as a function of a training system user'"'"'s prior club selection, lesson selection and readiness indication, sensor signals received from the multiplexer during a golf club swing to identify faults therein and to select and output to a video display unit and at least one speaker recorded audio-visual responses that contain appropriate information for correcting the faults.

2. The training system as defined by claim 1, wherein each of the plurality of sensors includes a matched, infrared, integrated emitter-detector pair.

3. The training system as defined by claim 2, wherein the plurality of sensors are supported by a resilient pad.

4. The training system as defined by claim 1, wherein the plurality of sensors include control sensors and club-head data sensors.

5. A computer-based, interactive sports training system, comprising:

a plurality of sensors, each sensor being capable of sensing proximity of a golf club head and of generating a sensor signal in response thereto, wherein the sensors include a club sensor, a next sensor and a ready sensor;

a multiplexer connected to the sensors to format sensor signals for communication to a computer; and

a computer program for directing the computer to analyze, at least as a function of a training system user'"'"'s club selection, lesson selection and readiness indication, sensor signals received from the multiplexer during a golf club swing to identify faults therein and to select and output to a video display unit and at least one speaker recorded audio-visual responses that contain appropriate information for correcting the faults.

6. The training system as defined by claim 5, wherein the computer program contains instructions to direct the computer to operate according to club, lesson and ready commands selected by a user of the training system by positioning the golf club head proximate an appropriate control sensor.

7. The training system as defined by claim 6, wherein the computer program contains instructions to direct the computer to determine, from the pattern, order and relative timing of club-head data signals, the path, height, impact speed, and face impact angle of the golf club head and the right-handedness or left-handedness of the user.

8. The training system as defined by claim 7, wherein the video display unit is a computer monitor.

9. The training system as defined by claim 8, further including a data storage device, the computer program being stored within the data storage device, and further including instructions to direct the computer to display, on the computer monitor, a simulated flight path of a golf ball struck by the golf club head, the flight path being within a displayed environment defined by data also stored within the data storage device.

10. The training system as defined by claim 9, wherein the data storage device includes a compact disk read-only memory.

11. The training system as defined by claim 10, wherein the computer program further includes instructions to direct the computer to display, on the video display unit, a simulated golf course upon which a simulated golf game can be played by a user of the training system, the simulated golf course being defined by data stored within the data storage device.

12. The training system as defined by claim 10, wherein the plurality of sensors are disposed in a plane, the training system further including a calibrator bar guidably translatable across the plane of the club-head data sensors, differences in the times that the passing calibrator bar is detected by the sensors being stored in a calibration table for comparison with future golf club head detection times to compensate for sensor misalignment.

13. A method for training a golfing student using a computer-based, interactive sports training system, the method including the following steps:

identifying a selected golf club using a club sensor which detects proximity of the golf club prior to a swing thereof;

sensing the proximity of a golf club head during a swing thereof;

multiplexing sensor signals generated by the sensors in response to the passage of the golf club head and communicating formatted signals to a computer;

directing the computer to analyze, as a function of a training system user'"'"'s prior club selection, lesson selection and readiness indication, sensor signals received from the multiplexer during a golf club swing to identify faults therein; and

selecting and outputting, to a video display unit and at least one speaker, recorded audio-visual responses that contain appropriate information for correcting the faults.
