Abstract
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 Analysis
Total Claims: 24
Claim 1
Independent Claim
159 words
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.
Claim 2
Independent Claim
159 words
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.
Claim 3
Dependent Claim
22 words
The method of claim 1, wherein the center of gravity of said model is balanced for the demands of the physical activity.
Claim 4
Dependent Claim
32 words
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.
Claim 5
Dependent Claim
42 words
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.
Claim 6
Dependent Claim
45 words
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.
Claim 7
Dependent Claim
38 words
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.
Claim 8
Dependent Claim
11 words
The method of claim 6, wherein the physical skill comprises running.
Claim 9
Dependent Claim
57 words
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.
Claim 10
Dependent Claim
36 words
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.
Claim 11
Dependent Claim
