Interactive combat game between a real player and a projected image of a computer generated player or a real player with a predictive method

Abstract

A method for engaging a player or a pair of players in a motion related game including the steps of attaching plural colored elements onto selected portions of the player(s) garments and processing a video stream of each of the players to separately identify the positions, velocities an accelerations of the several colored elements. The method further comprises generation of a combatant competitor image and moving the image in a manor to overcome the player. In a further approach, two players are recorded and their video images are presented one screens frontal to the other of the players. The same colored elements are used to enable computer calculations of fighting proficiency of the players.
