1. A system for generating performance metrics for a user comprising:
- at least two arm sensors operable to sense user arm movement in an x, y, and z direction and/or at least one head sensor operable to sense user head movement in an x, y, and z direction; and
at least one processor operable to determine performance metrics for the user based on the movement sensed by the arm and head sensors.

Abstract
A method and system relates to locating or otherwise generating positional information for an object, such as but not limited generating positional coordinates for an object attached to an athlete engaging in an athletic event. The positional coordinates may be processed with other telemetry and biometrical information to provide real-time performance metrics while the athlete engages in the athletic event.

17. A method of identifying a swimming stroke performed by a swimmer to be one of a crawl, back, breast, and butterfly stroke, the method comprising:
-
receiving a signal from each of one or more sensors attached to at least one of a head and one or more arms of the swimmer, each signal representing movement of the corresponding sensor relative to an x, y, and z axis; processing the signals to identify the swimming stroke to be the crawl stroke in the event at least one of; (i) the signals indicate the head to be orientated head-up and the swimmer'"'"'s arms to be alternating; and (ii) the signals indicated the head to be orientated head-up and rolling side-to-side; processing the signals to identify the swimming stroke to be the back stroke in the event the signals indicate the head to be orientated head-down; processing the signals to identify the swimming stroke to be the breast stroke in the event at least one of; (i) the signals indicate the swimmer'"'"'s arms to be alternating and the swimmer'"'"'s hand angle moves to a vertical position when swimming; and (ii) the signals indicate the head to be orientated head-up, the head is not rolling side-to-side, and a stroke pattern best-fits with a known breast stroke pattern; processing the signals to identify the swimming stroke to be the butterfly stroke in the event at least one of; (i) the signals indicate the swimmer'"'"'s arms to be alternating and the swimmer'"'"'s hand angle remains in a flat position when swimming; (ii) the signals indicate the head to be orientated head-up, the head is not rolling side-to-side, and a stroke pattern best-fits with a known butterfly stroke pattern.

18. A method of counting a number of strokes performed by a swimmer based a movement signal generated by at least one of an arm sensor and a head sensor during a swum lap, the method comprising:
-
identifying a dominate stroke period of the swum lap from the movement signal; selecting a portion of the movement signal coinciding with one of the dominate periods to be a first reference stroke; filtering the movement signal based on the first reference stroke to identify a number of potential strokes; and determining the number of strokes based on the identified number of potential strokes. - View Dependent Claims (19, 20)
