Abstract

An instrument gathers and processes data from one or more capture devices. The data can thereafter be processed using one or more classification techniques to properly detect and/or reproduce motions for an application. The present invention can be used both outdoors and indoors.

Claims

1. A computer-readable medium storing instructions that, when executed by a computing device, cause the computing device to perform a method comprising:

a. obtaining one or more signals from at least one motion capture device; and

b. using a classification technique to classify a movement.

2. The computer-readable medium of claim 1, wherein the motion capture device is coupled a body part.

3. The computer-readable medium of claim 1, wherein the one or more signals are obtained wirelessly from the at least one motion capture device.

4. The computer-readable medium of claim 1, wherein the method further includes filtering the one or more signals obtained from the at least one motion capture device.

5. The computer-readable medium of claim 1, wherein the using classification technique includes:

a. interpolating the one or more signals using previously collected data from a history record to thereby determine a movement class; and

b. mapping the movement to at least one input event recognized by a primary application.

6. The computer-readable medium of claim 5, wherein the interpolating the one or more signals includes averaging a subset of values in a history record.

7. The computer-readable medium of claim 5, wherein the mapping the movement includes:

a. for each motion category, calculating a probability that the movement corresponds to that motion category based on the one or more signals and a history record;

b. based on calculated probabilities, determining a type of the movement; and

c. outputting the type of movement.

8. The computer-readable medium of claim 7, wherein the method further comprises storing the type of movement and corresponding information in the history record.

9. The computer-readable medium of claim 1, wherein the classification technique is one of a probabilistic network and a deterministic method.

10. A gaming kit comprising:

a. at least one pad, each configured to be in contact with a foot, includes;

1. one or more sensors for capturing motion data; and

2. a transmitter for transmitting the data to a computing device; and

b. a software application configured to be accessed by the computing device, wherein the software application uses the data.

11. The gaming kit of claim 10, wherein the software application is configured to retrieve information from an external source.

12. The gaming kit of claim 11, wherein the external source is the Internet.

13. The gaming kit of claim 11, wherein the external source is an external storage device coupled to the computing device.

14. The gaming kit of claim 10, wherein the computing device is a mobile device.

15. A system to map physical motion data to an action within a primary application, the system comprising:

a. a motion interpretation unit; and

b. an action mapping unit, wherein the motion interpretation unit and the action mapping unit are in communication with the primary application.

16. The system of claim 15, wherein the motion interpretation unit includes:

a. a signal processor configured to encode motion data into at least one of one or more states and one or more state transitions, and to pass motion data to the action mapping unit to be directly mapped to one or more actions within the primary application; and

b. at least one finite state machine configured to interpret the motion data and to communicate with the action mapping unit a working knowledge of each of the at least one finite state machine.

17. The system of claim 15, wherein the action mapping unit includes an action dictionary configured to map at least one of one or more states and one or more state transitions to one or more input events recognized by the primary application.

18. The system of claim 15, wherein the action mapping unit is at least partly integrated with the primary application.

19. The system of claim 15, wherein the motion interpretation unit is configured to periodically sample raw motion data from one or more motion capture devices.

20. The system of claim 15, further comprising a motion sensing unit, wherein the motion sensing unit includes one or more sensors.
