Abstract:

A football interactive simulation trainer for quarterbacks and kickers provides true perspective views of a simulated playing area during practice plays, as would be seen by a training player on a regulation size football field during an actual play. The trainer includes a sonic tracking system which has a plurality of ultrasonic transducers spaced apart around the perimeter of an actual playing area for detecting positions of the training player and motion of the football during a practice play. The transducers are selectively grouped and directed in selected directions to establish regions of overlap so that several of the transducers will simultaneously detect the positions of the training player and several of the transducers will simultaneously detect the motion of the football. A data processing system receives data signals from the transducers, and determines the positions of the training player and the trajectory of the football within the actual playing area. Reactions of the simulated players to the different positions of the training player are determined, and video images are projected onto the video display wall with changing values of magnification and lines of sight to provide the training player with the true perspective views of the simulated playing area.
