Abstract

A training device for a person performing a physical activity wherein the proper performance thereof is related to the proper movement by the person. The device comprises a movement sensor, a trigger event sensor for sensing the occurrence of a specific physical trigger event, a processor, an electronic memory, and a protective enclosure. The movement sensor provides movement signal values to the processor, which is able to store these movement signal values in the memory. The trigger event sensor provides trigger event signal values to the processor, such trigger event signal values corresponding to the occurrence of the specific physical trigger event near the device. The processor is able to store the trigger event signal values in the memory and evaluate the trigger event signal values to determine if the specific trigger event has occurred. Upon detection of the trigger event, if the movement signal values are not within a first pre-defined range, the processor takes a first notification action. Otherwise, the processor takes a second notification action. A notification transducer is included for signaling the notification actions of the processor to the person, who is thereby notified of the correctness of his performance of the physical activity relative to the occurrence of the particular trigger event. The processor may also evaluate other characteristics of the trigger event signal values to determine the correctness of the performance of the physical activity.

Claims

1. A training device for a person performing a physical activity comprising:

means for sensing a trigger event, such trigger event being related to the interaction of the person directly or indirectly with an object,

means for sensing and recording a movement of the person as data, said movement data being sensed and recorded for a time duration, said time duration beginning at least before the occurrence of the trigger event and ending either a short duration after the trigger event or after the occurrence of a predetermined amount of time;

means for programmed processing of the data, including a memory means for recording the data;

and means for presenting processed results to the person.

2. A device as claimed in claim 1 wherein the movement is sensed at least during two of the predetermined times, the predetermined times being during, and before or after the trigger event.

3. A device as claimed in claim 1 wherein the movement is sensed at predetermined times being during, before and after the trigger event.

4. A device as claimed in claim 1 including comparator means, the comparator means being for comparing a measure of the trigger event and a measure of the movement with predetermined data relating to the trigger event.

5. A device as claimed in claim 1 wherein the presentation means is selectively at least one of a visual, an audible or tactile presentation of at least one of the trigger event or movement.

6. A method for a person performing a physical activity comprising the steps of:

sensing a trigger event, such trigger event being related to the interaction of the person directly or indirectly with an object,

sensing and recording a movement of the person as data, said data being sensed and recorded for a time duration, said time duration being at least before the occurrence of the trigger event and ending either a short duration after the trigger event or after the occurrence of a predetermined time;

processing of the data through a set program;

recording the data in a memory means;

and presenting the processed remits of the data to the person.

7. A method as claimed in claim 6 wherein the movement is sensed at least during two of the predetermined times, the predetermined times being during, and before or after the trigger event.

8. A method as claimed in claim 6 wherein the movement is sensed at predetermined times being during, before and after the trigger event.

9. A method as claimed in claim 6 including comparing a measure of the trigger event and in measure of the movement with predetermined data relating to the trigger event.

10. A method as claimed in claim 6 wherein the presentation is selectively at least one of a visual or tactile presentation of at least one of the trigger event or movement.

11. A training device for a person performing a physical activity, a proper performance of the physical activity being related to the movement of a movable entity by the person, the training device comprising:

electronic evaluation means including movement sensing means, trigger event occurrence sensing means for sensing the occurrence of a specific trigger event, processing means, and memory means, the movement sensing means providing movement signal values to the processing means, the processing means storing the movement signal values in the memory means, the trigger event sensing means providing trigger event signal values to the processing means, the trigger event signal values corresponding to the occurrence of the specific trigger event near the device, the processing means evaluating the trigger event signal values to determine if the specific trigger event has occurred, and;

a protective enclosure for housing the electronic evaluation means, the enclosure fixed to the movable entity;

the processing means having means for evaluating the movement signal values stored in the memory means to determine if the stored movement signal values are within a first pre-defined range of values relative to the occurrence of the trigger event, such that if the stored movement signal values are not within the first pre-defined range of values, the processing means takes a first pre-defined notification action, and such that if the stored movement signal values are within the first pre-defined range of values, the processing means takes a second pre-defined notification action.

12. The training device of claim 11 further including an electrical switch means that causes the processing means to begin storing the movement signal values in the memory means.

13. The training device of claim 12 wherein the processing means stops storing the movement signal values in the memory means a first pre-defined time after the particular trigger event has occurred.

14. The training device of claim 13 wherein the processing means stops storing the movement signal values in the memory means a second pre-defined time after the processing means begins storing the movement signal values in the memory means.

15. The training device of claim 11 wherein the trigger event sensing means includes a microphone and the particular trigger event causes an audible characteristic signal.

16. The training device of claim 15 wherein the characteristic audible signal is the sound of a golf ball being struck by a golf club, and the movable entity is the head of the person.

17. The training device of claim 15 wherein the characteristic audible signal is the sound of a ball being struck by a racquet, and the movable entity is the racquet.

18. The training device of claim 15 wherein the characteristic audible signal is the sound of a ball being struck by a bat.
