Abstract

A complete closed-loop system of capture, analysis, and corrective feedback uses small unobtrusive, strategically placed sensors on the ear, hip, knee, wrist, and/or ankle that communicate wirelessly to a base unit. The sensors capture movement during an activity to be analyzed, such as a golf swing, and send data to a base unit, which processes and transmits the data to a smart phone or other suitable portable and wireless communications device. The wireless communications device, in turn, transmits the processed data to a data base in the cloud (centrally based Internet software) where software instantly analyzes the motion represented by the processed data, then provides immediate feedback for improvement to the user.

Claims

1. A method of training in order to improve in the performance of a particular repeatable activity, comprising:

placing a motion sensor in a desired location;

activating a software application on a personal communications device for receiving data from said motion sensor, and transmitting the data to a remote processor;

conducting one repetition of a particular activity involving a repetitive motion;

using the remote processor to process the data received from said motion sensor, compare the received data to stored data, determine proposed corrective action based on the comparison, and generate processed feedback data representing the proposed corrective action; and

providing immediate visual feedback to a user by transmitting the processed feedback data to a display separate from the personal communications device and visible to the user while in position to conduct a next repetition, during the particular activity, regarding said proposed corrective action, so that the user may use the displayed processed feedback data to make adjustments before conducting a next repetition of the particular activity.

2. The method as recited in claim 1, and further comprising a step of activating a ground unit/system controller for receiving data collected by said motion sensor and transmitting said data to the personal communications device.

3. The method as recited in claim 1, wherein the particular activity comprises swinging a golf club.

4. The method as recited in claim 1, and further comprising activating an instructor website application portal having a data connection to said remote processor for viewing and evaluating the transmitted data.

5. The method as recited in claim 1, and further comprising a step of also providing immediate aural feedback to the user by transmitting aural suggestions regarding adjustments to be made before conducting a next repetition of the particular activity, wherein the aural feedback is received through an earpiece worn by the user while conducting the activity.

6. The method as recited in claim 1, wherein the placing step comprises placing the motion sensor on an instrument held by the user.

7. The method as recited in claim 1, wherein the placing step comprises placing a plurality of motion sensors in a plurality of desired locations.

8. The method as recited in claim 1, wherein the personal communications device comprises a smart phone.
