1. A method for tracking a first object and a second object within an area during a period of time, the method comprising: (6) (3)

obtaining magnetic field data for the first object within the area during the period of time;

obtaining magnetic field data for the second object within the area during the period of time; and

tracking positions of the first object and the second object at given times as they move about the area during the period of time based on the obtained magnetic field data for the first and the second object.

2. The method of claim 1, wherein the first object and the second object are tracked in real time as they move about the area. (0)

3. The method of claim 1, wherein the area comprises an athletic field. (0)

4. The method of claim 1, further comprising displaying a heat map that is indicative how much time the first object and the second object spent at various positions in the area. (0)

5. The method of claim 1, further comprising obtaining magnetic field data for the area. (0)

6. A method of claim 1, further comprising: (2) (2)

9. The method of claim 1, wherein the first and the second magnetic field data both comprise one of magnetic field intensity data and magnetic field direction data. (0)

10. A method for mapping a magnetic field of an athletic field area, the method comprising: (4) (2)

measuring magnetic field data at a plurality of locations within the athletic field area during a mapping session; and

generating a map of the magnetic field of the athletic field area based on the measured magnetic field data.

11. The method of claim 10, wherein the plurality of locations are equally spaced apart from one another. (0)

12. The method of claim 10, wherein at least one of the plurality of locations within the area comprises a boundary of the field of play. (0)

13. The method of claim 10, wherein at least one of the plurality of locations within the area comprises a goal. (0)

14. The method of claim 10, further comprising: (0) (2)

15. A method for determining performance information for an object located within an area, the method comprising: (5) (4)

obtaining magnetic field information for the area;

performing a statistical analysis of the variability of the magnetic field information for the area;

measuring a statistical variable of magnetic field data as the object moves within the area; and

determining performance information for the object based on the measurement of the statistical variable of magnetic field data.

16. The method of claim 15, wherein performing the statistical analysis of the variability of the magnetic field information for the area comprises determining a change in magnetic field intensity between points within the area, and wherein measuring the statistical variable of the magnetic field data as the object moves within the area comprises determining a number of changes in magnetic field intensity as the object moves within the area. (0)

17. The method of claim 15, wherein performing the statistical analysis of the variability of the magnetic field information for the area comprises determining a change in magnetic field direction between points within the area, and wherein measuring the statistical variable of the magnetic field data as the object moves within the area comprises determining a number of changes in magnetic field direction as the object moves within the area. (0)

18. The method of claim 15, wherein performing the statistical analysis of the variability of the magnetic field information for the area comprises creating a magnetic field data map. (0)

19. The method of claim 15, wherein performing the statistical analysis of the variability of the magnetic field information for the area comprises determining a distribution probability of magnetic field data within the area. (0)

20. The method of claim 15, wherein determining performance information for the object comprises determining a speed of the object as it moved within the area. (0)
