Abstract

A motion tracking system monitors the motions performed by a user based on motion data received from one or more sensors. The motion tracking system may include a motion tracking device with one or more sensors, a smart device with one or more sensors and/or a server. As the user interacts with the motion tracking system or smart device the motion data generated by one or more sensors is processed by a software application. The software application generates interpreted data based on the motion data and contextual data such as the equipment being used by the user. Feedback is then provided to the user during and/or after the user has performed a motion or a set of motions. The feedback provided to the user may be visual, audio or tactile. The application may be used to monitor a routine in a sporting, fitness, industrial or medical environment, for example.

Claims

1. A computer based method for interpreting repetitive movements performed by a user of a motion tracking device as part of updating a physical therapy treatment, the method comprising:

receiving motion data from the motion tracking device, the motion data representing motions performed by the user of the motion tracking device associated with a repetitive movement associated with the physical therapy treatment;

determining, by the computer, based on the motion data and the repetitive movement, a form with which the user performs the repetitive movement having the steps of;

identifying, by the computer, repetitive features in one or more signals of the motion data;

comparing, by the computer, the repetitive features with correct movement data associated with the repetitive movement; and

determining, by the computer, based on the comparison, the form with which the user is performing the repetitive movement including the steps of;

identifying, by the computer, repetitive features in one or more signals of the motion data;

comparing, by the computer, the repetitive features with correct movement data associated with the repetitive movement; and

determining, by the computer, based on the comparison, the form with which the user is performing the repetitive movement;

generating, by the computer, based on the determined form with which the user performs the repetitive motion, feedback, the feedback representing the form with which the user is performing the repetitive movement;

receiving an updated physical therapy treatment based upon the determined form.

2. The computer based method of claim 1, wherein determining, based on the repetitive features, the type of improper form being performed by the user comprises:

comparing the repetitive features with one or more improper movement data associated with the repetitive movement; and

determining, based on the comparison, the type of improper form being performed by the user.

3. The computer based method of claim 1, wherein the updated physical therapy treatment is modified to provide the user with better therapy options in response to the motion data.

4. A non-transitory computer-readable storage medium storing a computer program having instructions encoded thereon that, when executed by a processor, cause the processor to:

receive motion data from the motion tracking device, the motion data representing motions performed by the user of the motion tracking device associated with a repetitive movement associated with the physical therapy treatment;

determine, based on the motion data and the repetitive movement, a form with which the user performs the repetitive movement comprising;

identify repetitive features in one or more signals of the motion data;

compare the repetitive features with a correct movement data associated with the repetitive movement; and

determine, based on the comparison, the form with which the user is performing the repetitive movement including;

identify repetitive features in one or more signals of the motion data;

compare the repetitive features with a correct movement data associated with the repetitive movement; and

determine, based on the comparison, the form with which the user is performing the repetitive movement;

generate, based on the determined form with which the user performs the repetitive motion, feedback, the feedback notifying the user of the form with which the user is performing the repetitive movement; and

receive an updated physical therapy treatment based upon the determined form.

5. The non-transitory computer-readable storage medium of claim 4, wherein determine, based on the repetitive features, the type of improper form being performed by the user comprises:

compare the repetitive features with one or more improper movement data associated with the repetitive movement; and

determine, based on the comparison, the type of improper form being performed by the user.

6. The non-transitory computer-readable storage medium of claim 4, wherein the updated physical therapy treatment is modified to provide the user with better therapy options in response to the motion data.
