Abstract
The device for evaluating the efficiency of a ballplayer is provided with a target generator to control means whereby a visible target is rendered visible in a goal surface; the device further comprises means for measuring a parameter in relation with the speed of a ball going toward the goal surface and means for measuring the distance separating the target from the impact of the ball on the goal surface and computing means for determining the efficiency of the player in relation with the speed and position reached by the ball.
Claims6
A ball game practice and computing system in which a ball is thrown by a player from a normal rest position towards a goal surface and reches the goal surface with an instantaneous speed, said system comprising:
- a target generator for providing a visible target on the goal surface;
- means to control said target generator, whereby the visible target appears in a selected area of the goal surface;
- means for measuring the distance between the visible target and a point on the goal surface which is impacted by the ball thrown by the player;
- means for measuring a parameter related with the instantaneous speed of the ball at said impact point;
- means connected to the two said measuring means for computing a given relation between the parameter related to said speed and said distance, whereby the ratio of said parameter and of said distance is a data characterizing efficiency of the player.
