Abstract

A apparatus for recognizing a motion of an object is disclosed. The apparatus comprises a camera configured to photograph images of the object having the motion, a plurality of pressure and position sensors configured to be installed on a floor and to measure a floor contact position, a floor contact area and a floor contact pressure of the object and a motion analyzer configured to analyze the motion of the object by combining two or more among the images, floor contact position, floor contact area and floor contact pressure of the object.

Claims

1. A method of recognizing a motion of an object using multifaceted sensing, the method comprising:

photographing, by a camera, images of the object having the motion;

measuring, by a plurality of pressure and position sensors installed on a floor, at least one of a floor contact position, a floor contact area and a floor contact pressure of the object; and

analyzing, by way of a processor, the motion of the object by using the images and at least one of the floor contact position, the floor contact area and the floor contact pressure of the object.

2. The method according to claim 1, wherein the plurality of pressure and position sensors are arranged at a predetermined interval on a mattress.

3. The method according to claim 1, wherein the analyzing of the motion is performed in one of a computer, a server, and a display apparatus.

4. The method according to claim 1, wherein the analyzing of the motion is performed by combining two or more among changes in the images of the object, the floor contact position, the floor contact area, and the floor contact pressure over time.

5. The method according to claim 4, wherein the change in the floor contact position over time is used in analyzing horizontal activity of the object.

6. The method according to claim 4, wherein the change in the floor contact area over time is used in analyzing balance of the object.

7. The method according to claim 4, wherein the change in the floor contact pressure over time is used in analyzing moved height of the object.

8. The method according to claim 1, wherein a result from analyzing the motion is applied to an image of the measured object or a content object displayed on the display apparatus.

9. The method according to claim 1, wherein a result from analyzing the motion is applied to one among measurement of an object'"'"'s weight, face recognition, gesture recognition, measurement of moving speed, measurement of an exercise amount, and a game control signal.

10. An apparatus for recognizing a motion of an object, the apparatus comprising:

a camera to photograph images of the object having the motion;

a plurality of pressure and position sensors configured to be installed on a floor and to measure at least one of a floor contact position, a floor contact area and a floor contact pressure of the object; and

a motion analyzer configured to analyze the motion of the object by using the images and at least one of the floor contact position, the floor contact area and the floor contact pressure of the object.

11. The apparatus according to claim 10, wherein the plurality of pressure and position sensors are arranged at a predetermined interval on a mattress.

12. The apparatus according to claim 10, wherein the motion analyzer is provided in one of a computer, a server, and a display apparatus.

13. The apparatus according to claim 10, wherein the motion analyzer analyzes the motion by combining two or more among changes in the images of the object, the floor contact position, the floor contact area, and the floor contact pressure over time.

14. The apparatus according to claim 13, wherein the change in the floor contact position over time is used in analyzing horizontal activity of the object.

15. The apparatus according to claim 13, wherein the change in the floor contact area over time is used in analyzing balance of the object.

16. The apparatus according to claim 13, wherein the change in the floor contact pressure over time is used in analyzing moved height of the object.

17. The apparatus according to claim 10, wherein a result from analyzing the motion is applied to an image of the measured object or a content object displayed on the display apparatus.

18. The apparatus according to claim 10, wherein a result from analyzing the motion is applied to one among measurement of an object'"'"'s weight, face recognition, gesture recognition, measurement of moving speed, measurement of an exercising amount, and a game control signal.

19. A motion analysis apparatus comprising:

a processor to control one or more processor-executable units;

a first input unit to receive images of an object in motion;

a second input unit to receive at least one of a floor contact position, a floor contact area and a floor contact pressure of the object; and

an analyzer unit, to analyze, by way of the processor, the motion of the object by combining data received by the first input unit and the second input unit.

20. The apparatus according to claim 19, wherein the analyzing of the motion of the object by the analyzer unit comprises determining an amount or a type of physical exercise performed by the object.
