Abstract

A system and method is disclosed determining caloric burn via an HCI system. Using a capture device which is able to detect the thickness of a user'"'"'s arms, legs, torso, etc., the system determines a mass for each of a user'"'"'s body parts. Thereafter, in one example, the system measures caloric burn for a given body part as a function of how far the body part was displaced, a mass of the body part displaced and gravity.

Claims

1. In a system including a computing environment coupled to a capture device for capturing user motion, a method of determining caloric burn of a user of the system, comprising:

a) capturing an image of a body part of a user via the capture device;

b) determining a mass of the body part captured in said step a) via a processor of the computing environment using the image of the body part captured in said step a);

c) capturing a movement of the body part via the capture device; and

d) determining calories burned by the body part due to the captured movement of the body part in said step c) and the mass of the body part determined in said step b).

2. The method of claim 1, further comprising the step of displaying the calories burned as determined in said step d) via a display associated with the computing environment.

3. The method of claim 1, said step d) comprising the step of determining calories burned based on an upward movement of the body part.

4. The method of claim 1, said step d) comprising the step of determining calories burned based on at least one of a vertical movement, a horizontal movement, and a combination of vertical and horizontal movements.

5. The method of claim 1, said step d) comprising the step of determining calories burned based on maintaining a body part in a stationary, non-neutral position.

6. The method of claim 1, further comprising the step of performing the movement of the body part in response to one of an exercise application and a gaming application program displayed on a display associated with the computing environment.

7. The method of claim 1, said step b) of determining the mass of a body part performed by segmenting a user into limbs, head and torso from the scan of step a), determining a 3-D voxel group for a given limb, and determining a mass of the given limb based on the voxel group and a known density of the given limb.

8. The method of claim 1, said step b) of determining the mass of a body part performed by using a determined volume of the body part.

9. The method of claim 1, further comprising the step of calculating caloric burn of a user by calculating and summing caloric burn due to movement of arms, legs and torso.

10. The method of claim 9, further comprising the step of storing a running total of caloric burn of a user over one or more discrete time intervals.

11. A system, comprising:

a capture device capable of capturing an image of one or more discrete body parts of a user as the user moves within a field of view of the capture device; and

a computing environment associated with the capture device, the computing environment including a processor capable of calculating a mass of the one or more discrete body parts by a volume of the one or more body parts from one or more 3-D images of the one or more body parts captured by the capture device, and determining calories burned by the one or more discrete body parts due to the determined mass of the one or more discrete body parts and a direction and degree of movement of the one or more discrete body parts.

12. The system of claim 11, the computing environment further comprising storage for storing an aggregate total of the calories burned by the one or more discrete body parts over a period of time.

13. The system of claim 11, the computing environment calculating calories burned by one or more discrete body parts based on at least one of an upward movement of a body part, a downward movement of a body part, a horizontal movement of a body part and a combination of vertical and horizontal movements of a body part.

14. The system of claim 13, the computing environment further calculating calories burned by one or more discrete body parts based on a velocity of movement of the body part.

15. The system of claim 11, further comprising a display associated with the computing environment, the display displaying movements of the user and displaying the calories burned as determined by the processor.

16. The system of claim 11, the processor determining caloric burn of a body part when the body part moves from a neutral position to a non-neutral position, when the body part moves to a neutral position from a non-neutral position and when the body part is held in a non-neutral position.

17. A system for facilitating weight loss, comprising:

a capture device capable of capturing an image of one or more discrete body parts of a user as the user moves within a field of view of the capture device;

a computing environment associated with the capture device, the computing environment including determining a mass of the one or more discrete body parts captured by the capture device, and determining calories burned by the one or more discrete body parts due to the determined mass of the one or more discrete body parts and a direction and degree of movement of the one or more discrete body parts, the processor further running an exercise program; and

a display associated with the computing environment, the display prompting a user to perform exercises per the exercise program run by the processor, the display further displaying the calories burned as determined by the processor.

18. The system of claim 17, the computing environment calculating calories burned by one or more discrete body parts based on determined masses of the one or more discrete body parts, gravity, displacements of the one or more body parts and directions of displacements of the one or more body parts.

19. The system of claim 18, the computing environment further calculating calories burned by one or more discrete body parts based on a potential energy stored in one or more discrete body parts relative to a neutral position.

20. The system of claim 17, wherein the exercise program running on the computing environment causes the display to display an image of a person performing exercises that the user is supposed to mimic in order to burn calories.

21. A system, comprising:

a capture device capable of capturing an image of a user as the user moves within a field of view of the capture device; and

a computing environment associated with the capture device, the computing environment including a processor capable of segmenting the user into limbs, head and torso from the image of the user, determining a 3-D voxel group for a given limb, determining a mass of the given limb based on the voxel group and a known density of the given limb, and determining calories burned by the one or more discrete body parts due to the determined mass of the one or more discrete body parts and a direction and degree of movement of the one or more discrete body parts.

22. The system of claim 21, the computing environment further comprising storage for storing an aggregate total of the calories burned by the one or more discrete body parts over a period of time.

23. The system of claim 21, further comprising a display associated with the computing environment, the display displaying movements of the user and displaying the calories burned as determined by the computing environment.
