Abstract: A tennis training simulation system is disclosed that improves both reaction time and ground stroke techniques within a limited physical training environment. This training system combines simulated service of a tennis ball from a service line over a virtual net, and delivery of real tennis ball to an awaiting tennis student. In the system of this invention, the tennis ball delivery system includes an automatic tennis ball machine equipped with an array of lights or LED's that simulate the service of a tennis ball from a service line, a simulated trajectory of the tennis ball over a virtual net, and a simulated first bounce of a tennis ball coupled immediately thereafter with real in-flight delivery of an actual tennis ball to an awaiting tennis student.

Abstract: The device allows a beginner to learn the game, or an advanced player to develop new skills by simulating ball movement from the time that the opponent strikes the ball until the first bounce of the bail in the player's court. At this time a real ball is delivered at a speed and trajectory preset by the player. This simulation allows the practicing player to interact with the device in preparing stance and having a fluid back swing and swing of the tennis racket. The real ball having been struck by the player hits a large catch net located immediately in front of the device. The devise can be used in an enclosure the size of a one car garage or small basement, allowing use during rain or winter months.
