Abstract: A training device to enhance hand-eye coordination includes an illumination device for determining the proper time for an individual to strike a ball and to collect practice information for later evaluation. The device allows an individual to practice hitting a ball with a racket or bat, providing an immediate indication whether the ball has been properly struck. Also, an individual is provided with a record of his/her performance reviewable by a professional. The device includes a ball affixed to a flexible support assembly, the support and the ball reciprocating or pivoting when the ball has been struck. The location of the ball is constantly monitored each time the ball is struck. The amount of force applied to the ball when struck by an individual or implement can also be determined. Information relating to the manner in which the ball has been struck is recorded and is analyzed in real time.
