Abstract

Example embodiments may relate to a system, method, apparatus, and computer readable media configured for prompting a user to perform an exercise, monitoring form of the user while performing the exercise, and calculating an energy expenditure estimate for the user performing the exercise based on a type of the exercise and on the form of the user.

Claims

1. A computer-implemented method comprising:

receiving, by a computer device positioned on a body of a user, first data from a first sensor integrated into an item of apparel worn by the user;

determining, by a processor of the computer device, a location of the computer device on the body of the user, based on the received first data;

receiving, by the computer device, second data from a second sensor integrated within the computer device;

receiving, by the computer device, third sensor data received from a third sensor configured to detect a pressure exerted by the user;

calculating, by the processor, from the second sensor data and the third sensor data, an initial postural assessment of the user;

prompting the user to perform an exercise selected based on the postural assessment and a likelihood of injury to the user;

calculating, by the processor, from the second sensor data and the third sensor data, an angle between a first body part and a second body part of the user, based on the determined location of the computer device on the body of the user;

determining, by the processor, a form of the user, based on the calculated angle;

comparing the determined form of the user to a desired form associated with the exercise;

calculating, by the processor, a completeness modifier based on the comparing the determined form of the user to the desired form; and

calculating, by the processor, an energy expenditure estimate for the user performing the exercise based on a type of the exercise and on the calculated completeness modifier.

2. The method of claim 1, wherein the calculating of the energy expenditure estimate is determined utilizing a metabolic equivalent of task (MET) table for the type of the exercise.

3. The method of claim 1, wherein the energy expenditure estimate is based on a basal metabolic rate of the user.

4. The method of claim 1, wherein the calculating of the energy expenditure estimate applies the following equation:

Calories burned=BMR*(activity modifier)*(completeness modifier),

wherein BMR is a Basal Metabolic Rate of the user, and the activity modifier is an adjustment corresponding to the type of the exercise.

5. The method of claim 1, wherein the determining the form of the user is based on processing of video of the user performing the exercise.

6. The method of claim 1, wherein the calculating of the angle comprises:

processing of infrared data received from the first sensor and the second sensor.

7. The method of claim 1, wherein the comparing the determined form of the user to the desired form comprises comparison of the calculated angle to one or more threshold angle values.

8. The method of claim 1, wherein the calculating of the angle comprises:

processing of acceleration data received from the first sensor and the second sensor.

9. The method of claim 1, wherein the calculating of the energy expenditure estimate comprises increasing or decreasing the estimate based on the calculated completeness modifier.

10. A tangible, non-transitory computer-readable medium comprising computer-executable instructions that, when executed, perform a method comprising:

receiving, by a computer device positioned on a body of a user, first data from a first electronic sensor integrated into an item of apparel worn by the user;

determining, a location of the computer device on the body of the user, based on the received first data;

receiving by the computer device, second data from a pressure sensor;

calculating, from the received second data, an initial postural assessment of the user;

prompting the user to perform an exercise selected based on the postural assessment and a likelihood of injury to the user;

calculating, from the received second data, an angle between a first body part and a second body part of a user;

determining a form of the user, based on the calculated angle;

comparing the determined form of the user to a desired form associated with the exercise;

calculating a completeness modifier based on the comparing the determined form of the user to the desired form; and

calculating an energy expenditure estimate for the user performing the exercise based on a type of the exercise and on the calculated completeness modifier.

11. The non-transitory computer-readable medium of claim 10, wherein the energy expenditure estimate is based on a basal metabolic rate of the user.

12. The non-transitory computer-readable medium of claim 10, wherein the calculating of the energy expenditure estimate applies the following equation:

Calories burned=BMR*(activity modifier)*(completeness modifier),

wherein BMR is a Basal Metabolic Rate of the user, and the activity modifier is an adjustment corresponding to the type of the exercise.

13. The non-transitory computer-readable medium of claim 10, wherein the determining the form of the user is based on processing of video of the user performing the exercise or based on processing of an infrared reflection of the user.

14. The non-transitory computer-readable medium of claim 10, wherein the calculating of the energy expenditure estimate comprises increasing or decreasing the estimate based on the calculated completeness modifier.

15. An apparatus configured to be worn on a body of a user comprising:

at least one processor; and

at least one memory storing instructions that, when executed, cause the apparatus at least to perform;

receiving first data from a user-worn electronic sensor integrated into an item of apparel worn by the user;

calculating, from the first data, a location of the apparatus on the body of the user;

receiving second data from a sensor integrated within the apparatus;

receiving third data from a pressure sensor;

calculating, from the second sensor data and the third sensor data, an initial postural assessment of the user;

prompting a user to perform an exercise selected based on the postural assessment and a likelihood of injury to the user;

calculating, from the second sensor data and the third sensor data, an angle between a first body part and a second body part of the user;

determining a form of the user, based on the calculated angle;

comparing the determined form of the user to a desired form associated with the exercise;

calculating, by the processor, a completeness modifier based on the comparing the determined form of the user to the desired form; and

calculating an energy expenditure estimate for the user performing the exercise based on a type of the exercise and on the calculated completeness modifier.

16. The apparatus of claim 15, wherein the energy expenditure estimate is based on a basal metabolic rate of the user.

17. The apparatus of claim 15, wherein the calculating of the energy expenditure estimate applies the following equation:

Calories burned=BMR*(activity modifier)*(completeness modifier),

wherein BMR is a Basal Metabolic Rate of the user, and the activity modifier is an adjustment corresponding to the type of the exercise.

18. The apparatus of claim 15, wherein the determining the form of the user is based on processing of video of the user performing the exercise.
