How Does a Pool Table Recognize the Cue Ball?

A cue ball is not magnetic, but the innards of a pool table have a magnet that prevents it from falling into the cue ball hole. The magnet keeps the ball from falling into the hole and prevents the player from winning the game. This process is called ‘bounce detection’.

Coin-operated pool tables

Coin-operated pool tables can recognize the cue ball by a variety of methods. Some use oversized balls, while others use magnetic balls. Either way, coin-operated tables recognize the cue ball and automatically return it to the glass. Magnetic balls, on the other hand, tend to shatter and interfere with the game of advanced players.

Coin-operated pool tables are common in bars and pubs. They have mechanisms that separate the cue ball from the object balls and direct them to the exit. To play, you must first place a coin or token in the coin chute. To keep the table in good condition, it must always be clean and free of moisture. If you do not keep the balls clean, you will risk damaging them. DIY enthusiasts may attempt to force open the coin chute by drilling through the lock. If you do this, be sure to remove the slate and lock.

The standard size of a pool ball is 2 1/4 inches in diameter. However, the cue ball on a coin-operated table may be larger. Coin-operated tables use balls that are 2 3/8 inches in diameter. These balls are slightly larger than standard pocket billiard balls. The oversized balls can throw off a player’s shots. Some players complain about the size of the balls on coin-operated tables.

Coin-operated pool tables recognize the cuer ball by its size and magnetic center. A magnetic detector separates the cue ball from the numbered balls, and a deflecting device sends the ball into an opening on the side of the table.

Magnetic cue balls

Magnetic cue balls are used on many coin-operated pool tables. These balls contain a small magnet in the core, preventing them from falling down the chute and triggering a deflection device. This feature eliminates the need for large cue ball dispensers. However, it also has its detractors. The magnetic cue ball does not roll as smoothly as other balls, and this can be a problem for some players.

Magnetized balls can also disrupt the play of advanced players because they tend to lack a true roll. Magnetized balls have a higher tendency to shatter and are less durable than standard cue balls. However, there are a few advantages to using them. Despite their benefits, magnetic balls are not recommended for all players.

Magnetic systems were first patented by a company called Valley. Later, other manufacturers had to create their own designs. The magnetic system requires specially made metal cue balls. Magnetic coin-operated tables feature a slightly sloped trench with two ball tracks. A magnet on one side of the trench pulls the cue ball onto one track. The object balls travel down the second track.

Magnetic cue balls are a great alternative to conventional balls, and are also an excellent choice for coin-operated tables. Because they have a rough surface, the magnetized balls have a unique rolling motion. These balls are also known as mudballs, due to their irregular surfaces.

Ivory cue balls

The first step in determining whether a pool table uses ivory cue balls is to determine whether the ball is ivory. You can do this visually or by using a blacklight test. If you can’t determine the authenticity of the ball yourself, an expert’s opinion may be necessary. One way to tell whether a ball is ivory is to examine the pattern of the spider lines. If these lines are curved, the ball is probably ivory. A similar pattern can be found on mammoth and elephant tusks.

Another method of determining whether a cue ball is ivory is to examine the surface with a blacklight or a magnifying glass. If the ball is discolored, it probably isn’t ivory. This is because ivory is organic, and it will fade over time. If you have an ivory cue ball, you’ll be able to identify it from a sun-faded or old synthetic one easily.

Another way to determine whether a cue ball is ivory is to check for the Schreger lines. These lines look like small cross-hatched lines. If the lines are larger than 115 degrees, the ball is ivory. If they are shorter or longer, it’s probably not ivory.

An ivory cue ball should show up yellow under a blacklight test. While ivory is more expensive than plastic, it is not the only sign of an ivory ball. It will also be yellow if it’s made from bone or ivory dust.


The size of a cue ball on a pool table has a big impact on the gameplay of the game. Different sized balls make different shots easier or harder. However, if you play in a league, you’ll rarely find different-sized balls. In this article, we’ll take a look at how the cue ball compares to the other balls.

A standard pool ball is about two and a half inches in diameter and weighs about six ounces. The cue ball on a coin-operated table can be a little bigger. Coin-operated pool tables typically use a cue ball that’s 2 3/8 inches in diameter and weighs around six ounces.

The size of a cue ball on a pool table is usually determined by the table size and the nature of the game. Most blackball and pool tables are six or seven feet, and the object balls are smaller than the cue ball. In both games, the size of the cue ball on a pool table can make or break a shootout.

Some of the world’s best pool players prefer a shorter cue. They can have as much as twenty-four inches of clearance on the table. A 36-inch cue, however, is not commonly used by adult players, but is perfect for kids’ games. I personally prefer the Trouble Shooter cue over most other shorty cues because it has a better weight-to-length ratio.


A cue ball that hits the table will have a particular shape, a property called geometry. The shape of a cue ball is made up of three basic components: its length, backspin, and topspin. In most cases, the cue ball will strike the table at an angle of approximately 90 degrees. This angle can be broken by unusual spin or unequal mass. In these cases, a cue ball will have a different shape, requiring a stronger stroke.

First, the table needs to recognize the shape of the cue ball. The cue ball must be smaller than the table’s standard size. This means that larger balls will not fit through the table’s return chute. It will also refuse to accept anything larger than this. If you don’t want to ruin your game by trying to return an oversized ball, consider using a magnetic cue ball.

The gauging mechanism recognizes the shape of a cue ball by its radius. A smaller ball will pass through this mechanism, but a larger one will not. The gauging mechanism then separates the oversized ball from the normal ball. The smaller balls will fall through one chute, but the bigger ball will be directed through another chute and into the table’s head.

Despite the advantages of using a magnetic cue ball, pool tables need to be able to recognize the shape of a cue ball to play the game. The size of the cue ball and the magnetic properties of the ball are also important in recognizing the shape of the cue ball.


A computerized direction for pool table cue ball recognition system generates a signal to scan the playing surface of a pool table. The computer then breaks down the playing surface into a grid-coordinate system. This grid-coordinate system is used to determine where a ball is located on the playing surface.

In this experiment, fifteen examinees watched a demonstration of the system and subsequently were asked to identify a way to hit the cue ball. Twelve of the fifteen examinees failed to identify a shot way and commented that they knew how to hit the cue ball, but were not able to recognize the direction that the ball was pointing. The other twelve examinees said that they had learned the way to hit the ball from the system.

To implement a direction system, the computer must first detect the ball. Once this step is completed, the system will display the ball’s location in the right pool table image. The user will then click the center of the ball area. After clicking this area, the system will then use the projection matrix to estimate the ball’s location.

Another embodiment of the invention utilizes a video-based system to track the position of the billiard balls. This technology allows it to project the optimum ball paths onto the playing surface.
