ABSTRACT:
A method and system is provided which is particularly designed for board, lane or field games in which balls, pucks or the like are rolled, slid or otherwise propelled by a player over a horizonal support surface. Radiant energy emitters and detectors are providing along opposite sides of the support surface to detect crossings by the of detection lines including a first pair of lines perpendicular to a central reference line midway between such opposite side and a second pair of lines crossing the first pair of lines at points in the central reference line. Signals are developed which are applied to display a representation of the object which moves in a path and at a speed determined by the movement of the propelled object. Crossings of additional detection lines are detected to detect and display changes in speed and curvatures in the path of movement of the propelled object.
