Ergonomic motion and athletic activity monitoring and training system and method
First Claim
1. A method for executing an ergonomic action monitoring program, the method comprising the steps of:
- a. receiving a first image, the first image having luminous intensity information associated therewith;
b. storing luminous intensity information from the first image associated with a box corresponding to a subset of the image;
c. receiving a second image, the second image having luminous intensity information associated therewith;
d. storing luminous intensity information from the second image associated with the box;
e. comparing the luminous intensity information from the first image associated wit the box to the luminous intensity information from the second image associated wit the box; and
f. where the difference between the luminous intensity information from the first image associated with the box and the luminous intensity information from the second image associated with the box exceeds a predetermined threshold, actuating an alarm.

Abstract
This invention includes a system for teaching and learning a preferred ergonomic motion. The system includes a video camera for capturing successive images of a person executing an ergonomic motion. The system includes a threshold definition system that allows a user to define a spatial region of the video image through which motion should or should not interfere. If the spatial region is interfered, the system actuates an alarm, thereby providing feedback so the user may alter the technique of the next attempted motion. In one preferred embodiment, the system is used in teaching a golfer to execute a preferred golf swing. The golfer adjusts the spatial region to define a space through which neither the golfer'"'"'s body nor club should pass. If the spatial region is intruded upon, an alarm is actuated. For example, the golfer may define the region such that if the club moves off plane during a swing, a tee removal system causes the ball to disappear. In this manner, the golfer is only able to hit the ball when the club stays on plane. The invention works with reverse logic as well, and may equally be applied to any number of ergonomic activities.

7. A system for monitoring an ergonomic motion, the system comprising:
-
a. an image receiving circuit; b. a processor coupled to the image receiving circuit, wherein a spatial region of a video image corresponding to a preferred execution area of the ergonomic motion may be defined, wherein the processor; i. stores information associated with the spatial region of a first image; ii. stores information associated with the spatial region of a second image; iii. compares the information associated with the spatial region of the first image to the information associated with the spatial region of the second image; and iv. triggers an alarm when the information associated with the spatial region of the first image differs from the information associated with the spatial region of the second image by at least a predetermined threshold. - View Dependent Claims (8, 9, 10)
