When it comes to teaching basketball players how to execute a winning drive to the hoop, a tactic board can be a coach's best friend. But this top-down view of the court has a major limitation: It doesn't reveal how the opposing team will respond. A new program powered by artificial intelligence (AI) could change that. A coach sketches plays on a virtual tactic board on their computer, representing their own players as red dots and the defending team as blue dots. Once they drag their virtual players around to indicate movements and passes, an AI program trained with player movement data from the National Basketball Association converts these simplified sketches into a realistic simulation of how both offensive and defensive players would move during the play.
