20190168106
The present application relates generally to the field of billiards. More specifically the present disclosure relates to an interactive teaching tool including a grid configured to assist a user in lining up a shot on a billiards table.
The game of pocket billiards includes the following equipment: a pocket billiards table, a cue ball, a number of object balls, and an elongated stick. A traditional pocket billiards table is comprised of a flat-surface playing field covered in a cloth fabric, a number of raised rails surrounding the perimeter of the playing field, and a number of pockets situated about the perimeter of the playing field. Traditionally, the playing field of a pocket billiards table is rectangular in shape and there are six total pockets on the table—one pocket located in each of the four corners and one pocket located in the center of each of the two longer sides of the table. Such pockets are set within a frame of the pocket billiards table in such a way that allows for object balls located on the playing field to roll and sink into the pockets. A number of different billiard games may be played on pocket billiards tables such as 8-Ball, 9-Ball, straight pool, and snooker. While each game is made up of its own set of rules, the general objective is to sink a particular object ball into one of the table pockets by using an elongated stick to strike the target object ball with a cue ball.
Billiards is similar to pocket billiards, except that a billiards table does not include pockets. Instead, the object of billiards is to use a cue ball to push a striker ball into an opponent's cue ball.
When playing pocket billiards or billiards, it may be difficult for a player to visualize a shot and calculate a shot angle and trajectory. Therefore, a need exists for improved technology, including an interactive visual aid technology that would help players identify shot trajectories and conceptualize shot strategies necessary to proficiently pocket an object ball or strike an opponent's cue ball.

Billiard Aiming System
Referring to
The mobile device 150 may be, for example, a smartphone, a tablet, a personal digital assistant (PDA), a laptop, etc. One or more mobile devices 150 may be in communication with the billiard aiming system 1000 at any given time via any known wireless communication technology (e.g., WiFi, WLAN, Bluetooth, etc.). A user can manually enter a serial number provided on the billiard aiming system 1000 into the mobile device 150 to establish the connection, or the mobile device 150 may automatically detect the billiard aiming system 1000 and ask the user if he/she would like to connect the mobile device 150 to the billiard aiming system 1000. In some examples, the billiard aiming system 1000 may be connected to a router via a wired (e.g., Ethernet cable) or wireless connection to establish an Internet connection.
The billiard aiming system 1000 includes a housing 100 that contains a projector 110 and at least one sensor 120 configured to detect the billiards table 180 and the presence of one or more objects (e.g., a cue ball, an object ball, a striker ball, etc.) on the billiards table 180. The at least one sensor 120 may be, for example, a line sensor, a light sensor, an infrared sensor, an ultrasonic sensor, a color sensor, an image sensor (e.g., camera, digital camera, CCD camera, CMOS camera, etc.), or a combination thereof. In some examples, the housing 100 may contain an array of sensors 120. The projector 110 is configured to project an image, for example, an instructional grid 160, directly onto the playing surface 181 of the billiards table 180 and is mountable to a support surface 113, such as a ceiling or a wall, via a projector mount 112. The support surface 113 may be parallel to the playing surface 181 or at an angle that is not parallel to the playing surface 181. In some examples, the projector 110 projects the grid 160 using a light source and an optical lens. In other examples, the projector 110 projects the grid 160 directly using a laser. Referring to
The grid 160 includes an optional numbering system to facilitate learning. In the numbering system, the numbers on opposing rails vary by different increments. In the example of
The billiard aiming system 1000 further includes a computing system 170 (described in further detail below) configured to provide the mobile device 150 with information related to the presence of one or more objects on the billiards table 180. The mobile device 150 is configured to display information obtained from the computing system 170 and information related to potential shot trajectories on a user interface.
The at least one sensor 120 is configured to capture geometric and identification data of one or more objects on the playing surface 181 of the billiards table 180 such as the location of at least one indicator 182, end line 186, cue ball 183, object ball 184, pocket 185 or any combination thereof. The geometric and identification data obtained from the at least one sensor 120 are then communicated to a computing system 170 including a processor 140, a non-transitory memory 141, a logic unit 146, and a communication module 147 (i.e., a transmitter and a receiver, or a transceiver). The processor 140 is programmed to receive input data 142 from the at least one sensor 120, to follow instructions from the logic unit 146 to convert the input data 142 collected by the at least one sensor 120 into output data 143 that is sent by the communication module 147 to the mobile device 150. The communication module 147 is configured to wirelessly transmit the information to the mobile device 150 via any known wireless communication technology e Wi Bluetooth, etc.). An application on the mobile device 150 is configured to display suggested shot trajectories on a graphical user interface 151.
Method of Use
Referring to
In Step S7, the application on the mobile device 150 calculates and suggests potential shot trajectories based on the location of the objects on the playing surface 181 and various equations related to momentum, kinetic energy, angular velocity, etc. stored therein. For example, referring to the cue ball 183 as ball A for simplicity and the object ball 184 as ball B for simplicity, the general equation for conservation of linear momentum of the colliding balls may be calculated according to Equation 1:
m
A{right arrow over (V)}
1A
=m
A
{right arrow over (V)}
2A
+m
s
{right arrow over (V)}
2B (1)
where mA is the mass of the cue ball, mB is the mass of the object ball, V1A is the initial velocity of the cue ball, V2A is the velocity of the cue ball after impact with the object ball, and V2B is the velocity of the object ball after impact with the cue ball. For an elastic collision, kinetic energy is conserved according to Equation 2:
½mA(V1A)2=½mA(V2A)2+½mB(V2B)2 (2)
In general, it can be assumed that the cue ball and the object ball have the same mass, such that formula 2 simplifies to Equation 3:
(V1A)2=(V2A)2+(V2B)2 (3)
and that the object ball 184 is initially at rest (zero velocity). The initial velocity of ball A is V1A. After impact, ball A moves at velocity V2A in the direction shown, and ball B moves at velocity V2B in the direction shown. Using these equations, coupled with geometric equations such as the Pythagorean theorem, the application on the mobile device 150 provides instructions for the angle and speed at which the cue ball 183 should impact the object ball 184. For example, where the object ball 184 is hit at an angle close to zero, the cue ball needs be moving at a high speed V1A (i.e., the user should hit the cue ball 183 hard to apply a large force) because only a small fraction of the momentum (and therefore velocity) of the cue ball 183 is transferred to the object ball 184 due to the obliqueness of the impact. In cases where the cue ball 183 impacts a center of the object ball 184 (impact is head on), the momentum (and therefore velocity) of the cue ball 183 is completely transferred to the object ball 184 (V2A=0 and V2B=V1A) such that the user can hit the cue ball 183 with less force than in the previous example. The equations relied upon by the application on the mobile device 150 may also take into account friction between the cue ball/object ball and the playing surface. These equations are non-limiting examples of formulas that may be used by the application.
In some aspects of the billiard aiming system 1000, the computing device 170 includes a non-transitory memory 141 configured to store the input data 142 obtained from the sensor 120. The non-transitory memory 141 may be located inside or remotely located outside of the housing 100. Alternatively, or in addition, the output data 143 may be stored in a non-transitory memory on the mobile device 150. The stored input data 142 and/or output data 143 may be used to enhance the accuracy in calculating potential shot trajectories.
Machine learning or artificial intelligence may be used to take into account user traits, for example, a tendency of the user to hit the cue ball off-center or with too little force, to compensate for or provide additional suggestions in the suggested shot trajectories. A suggested shot trajectory is governed by a number of variables including but not limited to user input variables, variables stored in the non-transitory memory 141, identification variables, and/or geometric variables. User input variables correspond to information such as the type of game being played, the skill level of a given user, or the desired result of a user for a particular shot. Variables stored in the non-transitory memory 141 correspond to information such as the coefficient of friction of the playing surface 181 or the rebounding effect of the raised rails (i.e., the frame) surrounding the perimeter of the playing surface 181. Identification variables correspond to information that relates to the identity of billiard balls and tables elements. For example, the object balls 184 are typically identified by number, color, and marking. The two typical subsets of markings of the object balls 184 are stripes and solids. Geometric variables correspond to the location of elements contained along the playing surface 181 of the billiards table 180.
The user input variables, variables stored in the non-transitory memory 141, identification variables, and/or geometric variables may be used to calculate, among other things, the requisite shot force, shot angle relative to instructional grid 160, and linear and angular velocities of the cue ball 183. The identification of an element such as an object ball 184 for example, may be important in in different ways in different types of games. Therefore, a suggested shot trajectory may differ depending on the type of game being played or the classification of a ball as stripes or solids. Additionally, these variables also necessary to predict the effect of collisions between the cue ball 183, the object balls 184, and the end lines 186.
In some examples, the application on the mobile device 150 allows the user to connect with other users of the application. For example, the application may allow users to friend each other, chat with each other, follow each other, upload/view pictures or videos, etc. Information regarding a particular user's statistics (e.g., shots made or missed following the instructions provided by the application, common mistakes, etc.) may be uploaded to a central database that stores each user's statistics and used to enhance the predictive capabilities of the application, in particular, machine learning or artificial intelligence software.
The billiard aiming system 1000 described above projects an instructional grid directly onto the playing surface of a billiards table to facilitate teaching the basics of playing billiards. The billiards aiming system offers an interactive way to master billiards. By providing instant feedback to allow a user to quickly learn from their mistakes and to provide novices with a visual aid to facilitate learning essential techniques needed to proficiently pocket an object ball, with consistency, in a very short period of time.
