Abstract

Disclosed is an integrated sports assessment and information invention, applicable to most sports, designed to measure, calculate, derive, and analyze the resultant sport ball movement and ball-orientation characteristics in order to provide an assessment of the player'"'"'s performance and the circumstances surrounding the conduct of the sports action. The observed position and motion characteristics of the ball are continuously and empirically determined using measured data, environmental factors affecting the ball'"'"'s position and orientation are measured or derived. Related data is collected, stored, manipulated, and analyzed using 1^st, 2^nd and higher order statistics to generate output products for display of single or multiple occurrences based on any sport appropriate criteria. State-of-the-art display techniques provide the player, instructor or observer with valuable information regarding the player'"'"'s performance, the impact of the player'"'"'s action(s) or related circumstances on the ball'"'"'s travel-path that will enhance performance, understanding and enjoyment of the sport.
