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.
