## Abstract

An accelerometer is mounted on a location of a user's body, sports equipment, or other device and tracks movement. Data describing the user's movement(s) may be saved or uploaded for distribution. The user's movement(s) may be compared to previously saved or downloaded movement data and an audio, vibrational, electrical, or other alert may be activated when the movement data is outside a predetermined range from the previously saved, pre-programmed, or downloaded movement. The invention is useful at least in various forms of physical therapy, sports training, and job training, and provides synergy when utilized in conjunction with other motion help related devices.

## Claims

### Claim 1

A device comprising:
an accelerometer;
a processing device configured to receive accelerometer data from the accelerometer, identify a relevant motion in the accelerometer data, and compare the motion to previously stored motion(s); and
a feedback mechanism configured to notify a user of the device about at least one aspect of the motion derived from the comparison while the motion is occurring;
wherein:
the feedback mechanism comprises multiple points of feedback individually energized in a manner representative of a magnitude of motion error identified in the accelerometer data;
the feedback is a different pitch or tone for different variations from a desired motion;
the at least one aspect of a user motion comprises an amount of deviation from a desired motion; and
the notification of the at least one aspect occurs while the deviation is occurring.

### Claim 2 (depends on 1)

The device according to claim 1, wherein the amount of variation is communicated to the user via at least one of volume and frequency of the feedback.

### Claim 3 (depends on 1)

The device according to claim 1, wherein the amount of deviation comprises deviation in at least one of position at a predetermined portion of the motion and speed at the predetermined portion of the motion.

### Claim 4 (depends on 1)

The device according to claim 1, wherein the previously stored motion(s) comprises at least one of a motion recorded by the device via a user motion, a motion recorded by a similar device by a coach or trainer, and a motion pre-recorded and downloaded to the device.

### Claim 5 (depends on 1)

The device according to claim 1, wherein an identified motion is compared to a plurality of stored motions and wherein the comparisons are performed in order starting with a most common motion first.

### Claim 6 (depends on 1)

The device according to claim 1, wherein the motions are identified via multiple axis testing.

### Claim 7 (depends on 1)

The device according to claim 1, wherein the comparison comprises dividing each motion into a plurality of segments and applying an envelope to each segment.

### Claim 8 (depends on 1)

The device according to claim 1, further comprising recognizing initial patterns of user movement indicative of a stroke to be performed, comparing the stroke in real-time or near real time to a corresponding stored motion, wherein the initial patterns are determined from analysis of a large data set collected across multiple users.

### Claim 9 (depends on 1)

The device according to claim 1, wherein the comparison data is determined based on a location of the user such that the comparison is selected based on a motion appropriate to the location.

### Claim 10 (depends on 1)

The device according to claim 1, wherein the comparison is performed by dividing the motion into segments and applying a specialized comparison for a segment.

### Claim 11 (depends on 10)

The device according to claim 10, wherein the specialized comparison comprises a set of data fitted to a curve and applying the motion to the curve.

### Claim 12 (depends on 1)

The device according to claim 1, wherein the notification to the user is a non-alpha numeric audio or vibrational notification that is corrective in degrees such that it indicates an amount and direction of corrective action needed by the user to transform the motion in to a desired motion.
