Abstract

A system and method for teaching a student physical skills. The system includes a processing means for producing and displaying a model of the student. The processing means includes a computing means for generating the model. The model having the exact physical dimensions of the student and superiorly performs the skill. A video imaging means captures the movement of the student attempting to perform the skill and generates a video signal for effecting input into the processing means. The processing means coordinates the movement of the model with the movement of the student and generates a pixel image representation of the model overlayed on the student. The model is generated from a plurality of elite performers capable of superior performance. The model is enhanced with superior chacteristics of performing the skill, but constrained to human capabilities.

Claims

1. A method for teaching a physical skill to a person, said method comprising the steps of:

permitting the person to perform the physical skill without attaching radiation emissive devices to the parts of the person'"'"'s body involved in the skill;

capturing a video image of the person performing the physical skill without detecting radiation emissions from devices attached to the parts of the person'"'"'s body involved in the skill;

projecting onto a video display a first video image of the person endeavoring to accomplish the skill;

projecting simultaneously on the same video display a second video image of a model accomplishing the same skill while scaling the second video image of the model to the physical dimensions of the first video image of the person;

comparing the second video image of the model to the first video image of the person; and

attempting to correct the person'"'"'s performance of the physical skill to coincide with that of the model.

2. The method of claim 1, wherein the center of gravity of said model is balanced for the demands of the physical activity.

3. The method of claim 1, wherein said second video image is representative of a plurality of persons chosen from a predetermined group of persons who perform the skill in a superior manner.

4. The method of claim 3, further including the steps of:

identifying superior characteristics in the performances of the persons in the group; and

adding representations of the superior characteristics to the second video image for generating a representation of superior model performance.

5. The method of claim 1, further comprising the step of superimposing the second video image on the first video image with the physical dimensions of the second video image representing the model coinciding with the physical dimension of the first video image representing the person.

6. The method of claim 5, further including the step of coordinating the first and second video pictures representing the movements of various parts of the model'"'"'s body and the person'"'"'s body simultaneously at the same video display rate.

7. The method of claim 6, wherein the physical skill comprises running.

8. The method of claim 6, wherein the physical skill includes a manipulation of equipment and wherein said method further includes the step of coordinating a representation of the manipulation of the equipment by the model in the second video image with a representation of the manipulation of the equipment by the person in the first video image.

9. The method of claim 8, further including the step of superimposing the second video image of the equipment manipulation of the model to coincide with the first video image of the equipment manipulation by the person.

10. The method of claim 9, wherein the physical skill comprises an athletic event such as the swinging of a golf club.

11. The method of claim 9, wherein the physical skill comprises swinging a baseball bat.

12. The method of claim 1, further comprising the steps of:

initially recording the first video image of the person prior to simultaneously projecting the first and second video images; and

thereafter

simultaneously projecting the recording of the first video image with the second video image, so that the person can view and compare his or her recorded performance with that of the model.

13. A system for teaching a physical skill to a student, said system comprising:

a video camera;

a decoding means;

a processing means;

a storage means for storing a representation of a model accomplishing the skill;

a display means;

said video camera positioned for generating a video signal to provide a sequence of video images representative of the movement of a student attempting to perform the physical skill without radiation emissive devices attached over that part of the student'"'"'s body involved in the skill;

said decoding means converting said video image signal to pixel image data for effecting an input into said processing means;

said processing means simultaneously matching the movement of the student to an output from said storage means representing the model accomplishing the skill, said processing means generating a pixel image representation of the movement of the model and the movement of the student, wherein the model'"'"'s physical characteristics coincides with the student'"'"'s physical characteristics; and

said display means displaying said pixel image for comparing the student'"'"'s movement to the model'"'"'s movement whereby the student, learns the skill by attempting to duplicate the model'"'"'s movement.

14. The system of claim 13, wherein said processing means includes a digital computation means for computing the orientation and position of the model and providing digital signals representative thereof.

15. The system of claim 14, wherein said processing means includes an image processing means responsive to said digital signals and said pixel image data from said decoder for combining said digital signals with the pixel image data for generating a pixel image of the model and the performer.

16. The system of claim 15, wherein said computation means includes:

a central processing unit means for performing arithmetic operations on information in said processing means; and

a memory means for controlling the sequence of operation of said processing means and for storing information.

17. The system of claim 14, further including a means for providing input information to said image processing means.

18. The system of claim 13, further including a first video recorder for recording the video signal from said camera and adapted to playback said video signal for repeating the movement of the student.

19. The system of claim 13, further including an encoding means for converting the pixel image data to a video signal.

20. The system of claim 19, further including at least one video monitor for converting said video signal to a video image.

21. The system of claim 13, wherein said encoding means is a RGB to NTSC converter.

22. The system of claim 13, wherein said decoding means is an NTSC to RGB connector.
