Abstract
Abstract An arrangement for use in training players of a game during a simulated game session in the correct use of a game implement that has to be moved properly during an actual game to encounter a ball and impart to the latter a desired trajectory of movement after impacting the same includes light-emitting devices that emit at least one initial and two subsequent detection light beams from locations arranged at the corners of a triangle into substantially vertically oriented upwardly conically diverging spatial sectors. A reflective surface associated with the implement reflects the light of the respective detection light beam back to the respective location as the implement passes through the respective spatial sector with an intensity that is in a predetermined functional relationship when reaching the respective location to the distance of the reflecting means from the same location and to the degree of penetration of the reflecting means into the respective spatial sector. Respective photosensors are provided at each of the locations and sense the intensity of the detection light returning to the location substantially only from the spatial sector after having been reflected from the implement as it moves through the respective spatial sector. The thus detected peak of the intensity of the returned light and the time at which such peak had occurred at each of the locations are then used to determine the respective distances of the implement from all of the locations and the times of passage thereof past such locations and from that various parameters of the movement of the implement including its speed and various angles assumed thereby while moving in a path above the arrangement towards a ball encounter location.
