Abstract:
A laser beam pool ball teaching method employs a laser-beam generator () on a pool table () to direct a laser beam () from the laser-beam generator to beam a desired laser-beam spot () on a pool ball () on the pool table to be impacted by a cue ball () that is impelled from a cue-ball position on the pool table by a cue with which the cue ball is struck by a pool player for causing the pool ball to travel to a pool-table target () intended by the pool player. For beaming the desired laser-beam spot, the laser-beam generator is placed on the pool table at a position from which the laser beam can be directed to the desired laser-beam spot and be seen effectively by the pool player from a player position from which the pool player impels the cue in accordance applicable pool-playing rules. The desired laser-beam spot is determined by experience, skill, vector analysis and computer-aided calculation selectively. Computer controls can be applied with a computerized controller () in computer communication with the laser-beam generator.
