Fight analysis system

Abstract

A fight analysis system to objectively determine the quality and quantity of strikes in a fight. In one exemplary embodiment, one fighter wears a plurality of passive RFID tags at different locations that are read by a striking module (e.g., a knife) when the striking module lands on, or comes in proximity to, the fighter, to provide the location of a strike. Force sensors in the striking module enable determination of the type and force of a landed strike. In another exemplary embodiment, force sensors (e.g., pressure sensors used with fluid bladders) are used to determine both the location and the force associated with a landed strike. A graphical user interface module displays information gathered by the fight analysis system.
