The present invention relates to two integrated billiard balls for training, which include an image ball and an object ball assembled together by a connecting means and integrated through spherical contact therebetween so that, at the time of billiard training, a trainee can figure out a situation in which the trainee can hit the object ball coupled to the image ball of the training billiard balls, with a predetermined thickness, just by accurately hitting a cue ball while aiming the center of the image ball. Therefore, the present invention enables a trainee to easily practice thickness adjustment of an object ball and thus improve his or her billiard capability.

A method for determining the likelihoods of a cue sport player completing a run of shots for each of a plurality of non-break ball patterns is provided. The method initially involves operating a computer to retrieve a non-break ball pattern of the plurality of non-break ball patterns and to then facilitate the positioning of balls on a cue sport table in accordance with the non-break ball pattern. The positioning may be accomplished by use of a projector under control of the computer that projects ball positioning patterns on the sport table. The progress of the cue sport player through a run of the balls on the table is then monitored and the outcome of that progress, e.g. the number of balls in a run that are pocketed are recorded in association with the current non-break ball pattern. The procedure is repeated for further non-break ball patterns of the plurality of non-break ball patterns and the computer is then used to determine odds associated with runs for each of the non-break ball pattern based on the recorded outcomes.

A device for determining a lag winner in billiards and method of use are provided. The method disclosed includes placing a lag winner determination device such that the device is alongside a side rail of the billiards table and closer to a head rail of the billiards table than billiard balls used in the lag. The method further includes activating an illumination source within the lag winner determination device and moving the illumination source until it provides incident light to one of the billiard balls used in the lag. The method further includes determining the winner as a player that used the billiard ball that received the incident light from the illumination source.

The present invention relates to two integrated billiard balls for training, which include an image ball and an object ball assembled together by a connecting means and integrated through spherical contact therebetween so that, at the time of billiard training, a trainee can figure out a situation in which the trainee can hit the object ball coupled to the image ball of the training billiard balls, with a predetermined thickness, just by accurately hitting a cue ball while aiming the center of the image ball. Therefore, the present invention enables a trainee to easily practice thickness adjustment of an object ball and thus improve his or her billiard capability.

A lighting system for a billiard table comprising a frame, a plurality of lights disposed in the frame, and at least one lens coupled to the frame. The at least one lens is configured to focus a light produced by at least one light disposed in the frame.

The present invention relates to a device for inputting and controlling driving state information of a billiard ball for playing a billiard game in cyberspace and, more specifically, to a device for inputting and controlling driving state information of a billiard ball, in which an actual billiard ball is fixedly mounted on a standard table, wherein the billiard ball is mounted to be freely rotatable, and is hit by an actual billiard cue stick to receive the billiard ball's effecto information, rotation speed, and rotation direction, as well as driving state information for hitting strength and movement direction, and the received information is processed through driving state information processing software to display an image result reflecting the billiard ball's movement direction and movement amount on the actual billiard table, thereby making it possible to enjoy a billiard game in cyberspace as though a real game were being played.

A training aid for a cue sport is disclosed herein. The training aid includes a target line and a plurality of shot lines disposed on either side of a flat, compact device. Particularly, the training aid uses the fractional aiming method with improved cut angles to compensate for cut induced throw, thereby helping users improve their aim in cue sports, such as billiards, pool and snooker.

A striking assist method for a ball game such as snooker on a bounded table, a striking assist system, and a portable electronic device are described. The striking assist method includes acquiring pictures or videos of a snooker table in play, analyzing positions of balls in the pictures and the videos to get positions, calculating a striking path of at least one ball according to the position, and providing a striking suggestion to a user according to the striking path. The striking suggestion can be graphically or audibly provided to the user through the portable electronic device.

A spring-loaded billiard cue assembly for shooting cue ball in billiards includes a tube that may be gripped while playing the game of billiards. A rod is slidably positioned in the tube and the rod is urged into a retracted position having the rod being positioned in the tube. The rod is biased into an extended position having the rod extending outwardly from the tube for striking a cue ball in the game of billiards. A light emitter is coupled to the tube to emit a beam of light outwardly therefrom for aiming during the game of billiards.

A billiard aiming system includes a housing configured to be mounted to a ceiling above a billiards table; at least one sensor positioned within the housing and configured to detect a position and an identity of at least one object on a playing surface of the billiards table; and a projector positioned in visual communication with the billiards table and configured to project a grid on the playing surface of the billiards table. A system for teaching billiards includes a billiards table having a playing surface; the billiard aiming system, and a mobile device having a graphical user interface. The mobile device is configured to receive geometric data and identification data from the billiard aiming system and display instructions regarding a suggested shot trajectory on the graphical user interface based on the geometric data and the identification data.
