Abstract

Methods for determining performance information for an object located within an area include obtaining magnetic field information for the area, measuring first magnetic field data when the object is located at a first position within the area, and determining performance information for the object within the area based on the magnetic field information for the area and the first magnetic field data.

First claim

What is claimed is:

1. A method for determining performance information of an object located within an athletic field area, the method comprising, in order:
obtaining local magnetic field map data for the athletic field area at a plurality of locations in a grid-like pattern during a mapping session;
measuring magnetic field data when the object is located within the athletic field area;
filtering the measured magnetic field data; and
determining performance information of the object within the athletic field area based on the magnetic field map data and the filtered measured magnetic field data.

2. The method of claim 1 , wherein the magnetic field map data comprises data about a location of a field feature of the athletic field.

3. The method of claim 1 , wherein filtering the measured magnetic field data comprises factoring in physical space constraints of the athletic field.

4. The method of claim 1 , wherein filtering the measured magnetic field data comprises factoring in motion dynamics constraints of the object.

5. The method of claim 4 , wherein the object comprises a human and the motion dynamics constraints are based on human motion dynamics.

6. The method of claim 4 , wherein the object comprises a ball and the motion dynamics constraints are based on ball motion dynamics.

7. The method of claim 1 , wherein the measured magnetic field data comprises magnetic field intensity data and magnetic field direction data.
