Method of training physical skills using a digital motion analyzer and an accelerometer
First Claim
1. A method of teaching a physical skill to a student, comprising steps of:
- (a) creating a model for the student using a method comprising steps of;
(i) identifying and choosing a person to be used as a model;
(ii) letting said model person perform said physical skill and measuring accelerations of objects wherein said objects are chosen from a group of objects comprising parts of the body of the model and objects carried by the model;
(iii) storing the measured data in a storage area;
(iv) modifying said data to fit the student'"'"'s physical skills and limitations, by changing the speed and the corresponding acceleration by a predetermined scaling factor;
(b) playing back said model, using methods comprising audiovisual means;
(c) letting said student perform said physical skill and measuring accelerations of objects wherein said objects are chosen from a group of objects comprising parts of the body of the student and objects carried by the student;
(d) comparing the student'"'"'s motion with the model, using methods comprising audiovisual means;
(e) letting said student repeatedly execute said physical skill while monitoring his motion using audiovisual means in real time until the student'"'"'s motion substantially coincide with said model.

Abstract
A method of training and simulating physical skills using a digital motion analyzing device that measures the necessary and sufficient information to describe uniquely a rigid body motion. The device, comprising a programmable digital signal processor and a universal accelerometer, measures the acceleration and calculates the linear velocity, the angular velocity, the orientation, and the position of a moving object, and stores and plays back the motion using audiovisual means and compares it with other pre-recorded motions. The student can choose a model and try to imitate the model with the help of audiovisual means and biofeedback means. The device is portable. It can also be connected to a computer where the motion can be further analyzed by comparing it with a database comprising many other characteristic motions. If a projectile is involved, such as in a golf swing, the trajectory of the projectile is calculated.

9. A digital motion analyzing apparatus comprising a sensor unit, a signal-processor unit, and a sound-synthesizing unit wherein:
-
(a) said sensor unit comprising a plurality of acceleration sensors, signal amplifying means, signal transmission means for sending acceleration sensor signals to said signal-processor unit, and mounting means for mounting said sensor unit to a moving object; (b) said signal-processor unit comprising receiving means for receiving said acceleration sensor signals, an analog-to-digital converter for converting said signals to digital signals, a digital signal processor, a Read-Only-Memory (ROM), and a Random-Access-Memory (RAM); (c) said sound-synthesizing unit comprising digital-to-analog converters for, audio amplifiers, and speakers for synthesizing a stereophonic sound; wherein said synthesized sound uniquely and distinctly represents the motion of said moving object. - View Dependent Claims (10)
