Abstract

An apparatus for identifying a type of motion and condition of a user is disclosed. One apparatus includes a motion detection sensor operative to generate an acceleration signature based on sensed acceleration of the user, and a controller. The controller is operative to determine what network connections are available to the motion detection device, match the acceleration signature with at least one of a plurality of stored acceleration signatures, wherein each stored acceleration signatures corresponds with a type of motion of the user, wherein the apparatus distributes at least some of the acceleration signature matching processing when processing capability is available to the motion detection device though available network connections, and identify the type of motion of the user and identify a condition of the user based on the matching of the acceleration signature.

Claims

1. A method of detecting human condition and activity of a user, comprising:

generating, by a motion detection device that includes a motion detection sensor, an acceleration signature based on sensed acceleration of an object that represents motion of the user;

the motion detection device determining what network connections are available to the motion detection device;

matching the acceleration signature with at least one of a plurality of stored acceleration signatures of motions of human beings, wherein each stored acceleration signatures corresponds with a type of motion, wherein the motion detection device distributes at least some of the acceleration signature matching processing when processing capability is available to the motion detection device though available network connections;

identifying a type of motion of the user and identifying a condition of the user based on the matching of the acceleration signature with a stored acceleration signature.

2. The method of claim 1, wherein the type of motion comprises at least one of atomic motion, elemental motion and macro-motion.

3. The method of claim 1, wherein the stored acceleration signatures are stored in a common library and a specific library, and matching the acceleration signature comprises matching the acceleration signature with stored acceleration signatures of the common library, and then matching the acceleration signature with stored acceleration signatures of the specific library.

4. The method of claim 3, wherein the common library includes universal motion and activities acceleration signatures, and the specific library includes person acceleration signatures.

5. The method of claim 3, wherein the stored acceleration signatures of the common library are useable for matching acceleration signatures of motions of multiple humans, and the stored acceleration signatures of the specific library are useable for matching acceleration signatures of motions of a particular human.

6. The method of claim 1, wherein when matches are made with at least portions of particular stored acceleration signatures, then audio sensing of the object is activated.

7. The method of claim 1, wherein matching further comprises filtering the acceleration signature.

8. The method of claim 7, further comprising reducing a number of stored acceleration signature matches by identifying a previous activity of the user, and performing a time domain analysis on the filtered acceleration signal to identify transient signatures or steady-state signatures of the filtered acceleration signal.

9. The method of claim 1, wherein if the acceleration signature exceeds a threshold value, then audio sensing of the object is activated.

10. The method of claim 9, further comprising transmitting the sensed audio.

11. The method of claim 1, further comprising identifying an activity of the user based on a sequence of identified motions of the person.

12. The method of claim 1, further comprising transmitting information related to the identified type of motion when matches are made with particular stored acceleration signatures.

13. The method of claim 1, further comprising storing at least one of the plurality of stored acceleration signatures during an initialization cycle.

14. The method of claim 1, further comprising initiating a low-power sleep mode of the object when sensed acceleration is below a threshold for a predetermined amount of time.

15. The method of claim 1, wherein the motion detection device distributes the acceleration signature matching processing when the processing capability is available to the motion detection device through available network connections, and distributing the acceleration signature matching processing saves the motion detection device processing power.

16. The method of claim 1, wherein the motion detection device distributes the acceleration signature matching processing when the processing capability is available to the motion detection device through available network connections, and distributing the acceleration signature matching processing increases a speed of the motion detection device processing.

17. An apparatus for identifying a type of motion and condition of a user, comprising:

a motion detection sensor operative to generate an acceleration signature based on sensed acceleration of the user;

a controller, wherein the controller is operative to;

determine what network connections are available to the motion detection device;
