说明书全文 | In soccer, to be in control of the ball is of importance to every level of player. The ability to control an awkward bouncing ball quickly and effectively gives the player with the ball the immediate advantage. First touch is often the difference between success and failure in most situations during the match. As players get older, the game gets faster and demands more speed. Consequently, there is a greater need for first-time passes and a precise first touch on the ball. Often, players cannot always play a first-time ball; therefore, they must trap the ball or may have to dribble if no teammates are in position to receive a first-time pass. A player will typically do one of four things when controlling the ball: shield the ball by putting their body between the ball and the opponent, pass the ball, shoot the ball, or dribble the ball. The space and time a player has to do these things can depend on how good the player's first touch is when receiving the ball. Players can improve by developing a better touch or feel for the ball. A fine touch enables a player to be comfortable touching the ball with all parts of the foot as well as other parts of the body. It is helpful for players to practice controlling balls on the ground and balls in the air. Good ball control involves the ability to take the ball with one touch in such a way that a player can play the ball with his next movement without having to chase or reach for it. The document The document The invention relates to a ball throwing system as claimed in claim 1 and to a method of controlling a ball throwing device as claimed in claim 8.

Certain aspects, advantages and novel features of the inventions are described herein. It is to be understood that not necessarily all such advantages may be achieved in accordance with any particular embodiment of the inventions disclosed herein. Thus, the inventions disclosed herein may be embodied or carried out in a manner that achieves or selects one advantage or group of advantages as taught herein without necessarily achieving other advantages as may be taught or suggested herein. The features disclosed herein are described below with reference to the drawings. Throughout the drawings, reference numbers are re-used to indicate correspondence between referenced elements. The drawings are provided to illustrate embodiments of the inventions described herein and not to limit the scope thereof.
As described above, a soccer player's first touch of the ball is an important core skill to develop. A touch can be as simple as receiving a slow pass on the ground or as difficult as taking a top speed knuckling ball out of the air and straight down onto one's foot. Touch enhancement is a continual process; youth and professionals alike perpetually train to ever improve their first touch and ball handling skills. The skill of touch is typically trained by players forming pairs and passing the ball to one another. This training method can produce results but tends to fall short in providing a disciplined approach to training that enables progress measurement and goal-oriented improvement. Further, this technique requires a player to find another individual with which to practice, which is not always practical, particularly for serious athletes who devote significant time to their training. This disclosure describes a specialized ball throwing machine that can be used to improve a player's first touch and ball control, among other benefits. The ball throwing machine can be designed to throw, lob, pitch, or otherwise eject soccer balls toward a player, who can trap the balls or practice other ball control skills. The ball throwing machine may be controlled using a controller in the form of a handheld computing device or the like. The controller can include software and hardware that enables the player to remotely control the machine, for example, wirelessly. The controller can include functionality for recording a player's progress with ball training, and the player can upload this progress information to a software network application, which may be a web site or the like. The soccer network application can provide functionality for a remote coach to analyze the player's progress and provide a customized training program to the player based on the player's progress. As a result, the ball throwing machine can enable the player to track progress and receive remote coaching to improve that progress. These and other features of the ball throwing machine, controller, and associated soccer network application are described in detail below. The game of soccer is commonly known in some countries as "football" or "association football." For convenience, this specification refers solely to the term "soccer," although such usage should be considered synonymous with "football" and "association football." Further, embodiments of the ball throwing machine, controller, and soccer network application described herein can be used or adapted for sports other than soccer, some examples of which are described below. It should also be noted that although this specification refers primarily to using a ball throwing machine to train ball trapping skills, the ball throwing machine can be used to train other skills. For example, the ball throwing machine can be used to train passing, shooting, and stopping a soccer ball, among other ball skills. A ball throwing machine 10 is shown in The illustrated ball throwing machine 10 includes an outer housing 12 with an upper section 14 and a lower section 16. The ball throwing machine 10 can be that can be easily movable. For example, the ball throwing machine can include one or more motorized or non-motorized wheels 18. Some embodiments may also include one or more handles for securing the ball throwing machine while moving the same. As can be seen in Many different styles and types of hoppers can be used. As shown, the hopper 30 is a gravity-type hopper with a spiraling ramp 32 located around an internal tube 34. The tube 34 can be used to impart structural strength to the hopper and can also provide appropriate spacing such that balls within the hopper are able to properly rotate and move downward in the hopper. Alternatively, the tube 34 is not included in some embodiments. Rather, the hopper 30 merely includes the spiraling ramp 32. In another embodiment, the spiraling ramp 32 is omitted and the hopper 30 includes a tube 34 that holds a plurality of balls. In some embodiments, the hopper 30 can be transparent. For example, the outer material of the hopper may be clear Plexiglas or plastic, or a thin mesh-like fabric. This transparency can allow the user to view the balls in the hopper 30 and identify when the hopper 30 needs to be reloaded. The hopper 30 can have a top portion 36 and a bottom portion 38. The top portion 36 can be configured for receiving one or more balls into the hopper 30 and in some embodiments, can hold additional balls. The bottom portion can be configured to transition balls from the hopper 30 into a ball staging area 22. The hopper 30 can be used for storing balls when the ball throwing machine 10 is in use and/or when the ball throwing machine 10 is not in use. In some embodiments, the hopper 30 can be collapsible or detachable to decrease the size of the ball throwing machine 10, such as when the ball throwing machine is not in use. In some embodiments, the tube 34 can be a telescoping tube and the outer material of the hopper 30 can be fabric, such that the hopper 30 can increase or decrease in size. In some embodiments with the collapsible hopper 30, the top portion 36 can be collapsed to sit on top of the bottom portion 38. Alternatively, the tube 34 can be configured to be removable to remove structural support separating the top portion 36 from the bottom portion 38. Advantageously, in certain embodiments, the ball throwing machine 10 is designed to deliver soccer balls that are smaller than adult regulation size soccer balls to thereby enable more effective training of ball trapping skills. The smaller surface area of such balls can make the smaller balls harder to trap than regulation size balls (such as size "5" soccer balls). Training with smaller balls can therefore benefit a player using a larger, regulation-size ball in a match because the player may have obtained skills that transfer over to the easier-to-trap, larger ball. In some embodiments, the balls used with the ball throwing machine 10 are about half the size of regulation size 5 balls, about a third of the size of regulation size 5 balls, about a quarter of the size of regulation size balls 5, or some other size. For youth players who may already be using a smaller ball than an adult ball in matches, the ball throwing machine 10 can employ even smaller balls than the youth players use in their matches. For instance, if youth player is used to using size 4 soccer balls, the ball throwing machine can throw size 3 soccer balls or smaller, etc. However, in other embodiments, regulation size balls are used instead of smaller balls. The size of the balls used by the ball throwing machine 10 can be smaller than a regulation size 3 ball, even for older youth and adult players. For example, in one embodiment, the balls are preferably about 152 mm in diameter. However, in other embodiments the balls can range in size from about 132 mm to about 172 mm in diameter while still providing some or all of the benefits of the balls described herein. In still other embodiments, the balls can range in size from about 115 mm to 215 mm in diameter while still providing at least some of the benefits described herein. A ball that may be used herein may have any of the following characteristics: a rubber construction, a butyl bladder, one or more nylon plys (such as 1, 2, 3, or 4 or more nylon plys), spiral winding of the nylon plys, and the like. These and other characteristics of the balls, among others (including size, texture, weight, cover type, etc.) can be selected to achieve a desired liveliness or bounciness of the ball. Different balls may be provided with different liveliness for different levels of difficulty. For instance, a ball that has more bounce may be harder to trap and thus appropriate for a higher level of difficulty, while a ball with less bounce may be easier to trap and thus appropriate for a lower level of difficulty. Moreover, the colors of the balls can be selected to target foot-eye coordination. For example, the balls may be blue, green, or red, or a combination of the same, as these colors can be the easier to see than other colors. Alternatively, colors may be selected that are less easy to see so as to increase the difficulty of training. Different colors may be provided for boys and girls, who may perceive colors slightly differently. In one embodiment, the balls are not actual soccer balls. For example, a ball having a smaller size than a regulation size ball can be considered to be a ball other than a soccer ball. Counter intuitively, it can be beneficial to train soccer skills (such as trapping) using balls that are not soccer balls, such as any of the balls described herein. Balls used in other sports can also be thrown by the ball throwing machine 10 for the purposes of training soccer skills. Tennis balls, racquet balls, and squash balls, for instance, can be beneficially used to train trapping skills. Moving now to the bottom portion 16 of the outer housing 12, the bottom portion 16 is shown housing the ball staging area 22, as well as the ball delivery device 40. As can be seen in For example, as shown, the ball staging area 22 includes three ball stops 26. In some embodiments, the ball stops 26 can include a solenoid configured to advance and/or retract a rod or other member in front of a ball. The three balls stops 26 can allow the ball throwing machine 10 to control the projection of the ball completely with the ball delivery device 40. For example, separating the balls with multiple ball stops 26 can allow the ball delivery device 40 to pitch a ball without the influence of other balls acting or pushing upon the ball. It will be understood that the balls in the hopper may be pressing down on one another by gravity and could have an influencing effect on the trajectory of the ball, if allowed to contact the ball being pitched. However, fewer than three ball stops 26 may be included in the machine 10 instead. As is shown, the bottom portion 16 of the outer housing also includes at least one opening 20. The opening 20 can provide space for the ball to be thrown through to the user. The opening 20 can be one of many different shapes, such as oval, elliptical, rectangular, triangular, or any other desired shape. In some embodiments, the bottom portion 16 of the outer housing 12 includes a minimal amount of material, such that a majority, or at least a substantial portion, of the ball delivery device 40 is exposed and not enclosed. In such embodiments, little to no portion of the outer housing may be between the ball delivery device 40 and the user. Turning now to As illustrated, the ball delivery device 40 includes one or more wheels or balls 42 which are used to impart speed, spin, and/or other features of trajectory to a ball. The ball delivery device 40 can also include one or more motors 44 which are connected to the wheels 42 to thereby deliver speed and direction to the wheels 42. The ball delivery device 40 can also include a control unit 46 and a power source 48, such as batteries. The control unit 46 can include various features that can be used to control the ball delivery device 40. For example, the control unit 46 can include electronic circuitry, a processor, and memory having program instructions stored thereon for controlling the various electrical features of the ball delivery device 40, such as the motorized wheels 18 and actuators (described below). Further, the control unit 46 can include a wireless network interface card (NIC) and antenna or wired NIC for communicating with a controller device that sends commands to the ball throwing machine 10, as described below with respect to The ball delivery device 40 may also include one or more actuators 50. The actuator 50 can be used to control an angle of the ball delivery device, including the wheels 42. The ball delivery device 40 can include a frame having one or more brackets 52, 54. The brackets 52, 54 can be positioned in fixed relationship with one another. As shown, the actuator 50 is connected to at one end to bracket 52 and at an opposite end to bracket 56. The bracket 56 can be attached to the wheels and in some embodiments, the motors 44. The bracket 56 can also be hingedly attached to bracket 54. The actuator 50 can move to increase or decrease the length of the actuator. In the illustrated position of Moving now to Moving the actuator 50 illustrated in It will be understood that the ball delivery device 40 can function in many different ways, including ways different from those described herein. For example, rather than including an actuator, the ball delivery device 40 can be moved or positioned with one or more stepper motors connected directly between two rotating brackets. Further, although described as being primarily used for pitching soccer balls, the ball delivery device 40 can also be adapted to pitch other types of balls, such as baseballs, softballs, tennis balls, racquet balls, squash balls, cricket balls, lacrosse balls, volleyballs, and the like. A controller 120 is also shown and is in wireless communication with the ball throwing machine 10. The controller 120 can be a computing device of the player 130 (or the player's coach or parent), and may be, for example, a smart phone, tablet, laptop, personal digital assistant (PDA), or other wireless handheld device, or even a desktop in some embodiments. The controller 120 can communicate wirelessly with a wireless module in the ball throwing machine 10 (e.g., in the control unit 46). Alternatively, the controller 120 can be coupled with the ball throwing machine 10 using a cable or a docking station installed in the ball throwing machine 10. The controller 120 can include functionality for controlling the training programs that run on the ball throwing machine 10. For example, the controller 120 can include functionality for a user thereof, such as the player 130, coach, or a parent, to select training programs to be communicated to the ball throwing machine 10. Each training program can include a set of drills, commands, or instructions to be executed by the ball throwing machine 10, such as how many balls to throw in a given period of time, how fast, and with what trajectory. The training programs can be selected and customized by the player 130, a coach, or a parent. An optional camera 140 is shown in communication with the ball throwing machine 10 via a cable 142. The camera 140 can take pictures or video of the player 130 during training sessions. The camera 140 can transmit the pictures and/or video to the ball throwing machine 10 over the cable 142 (or a wireless link). In turn, the ball throwing machine 10 can provide the pictures and/or video to the controller 120 wirelessly. Alternatively, the camera 140 can communicate directly with the controller 120, for example, by wirelessly sending pictures and video to the controller 120. Further, in some embodiments, images or video can be taken of the player 130 using a camera in the controller 120 or a built-in camera in the ball throwing machine 10 (not shown) instead of or in addition to the camera 140. In addition, in some embodiments, the camera 140 can communicate with player recognition software running in a processor or controller of the ball throwing machine 10. This player recognition software can locate a player and cause the ball throwing machine 10 to automatically throw a ball to the player. The player recognition software can include facial recognition software but may also detect a player from features of the player other than the face. Advantageously, in some embodiments, the player 130 can use the controller 120 to submit pictures, video, or other player training data to a remote web site or network application (described below with respect to By way of overview, the ball throwing machine 10 communicates with the controller 220, for example, wirelessly using Wi-Fi (IEEE 802.11x), Bluetooth, Zigbee, or any other standard protocol(s). The controller 220 is a more detailed example of the controller 120 of In the depicted embodiment, the controller 220 includes a ball machine control module 222, a training module 224, and a safety module 226. Each of these components can be implemented with hardware and/or software. In one embodiment, the modules 222, 224, 226 are part of a controller application installed on the controller 220. The controller application may be obtained for installation on the controller 220 from an application store (such as the iTunes™ application store or Android™ Market application store), via computer-readable media (such as a USB key or DVD), or the like. In some embodiments, the controller 220 is sold or otherwise provided together with the ball throwing machine 10 with the controller application preinstalled. Other functionality may also be provided with the controller 220 in some implementations. The ball machine control module 222 of the controller 220 can provide functionality for a user (such as a player, coach, or parent etc.) to control the ball machine 10. For instance, the ball machine control module 222 can output a user interface that provides options for a user to select different types of training programs or individual ball throwing characteristics to be implemented by the ball throwing machine 10. This user interface can be implemented on a touch screen display of the controller 220 in some devices, although other types of controller 220 displays may also be used. In response to receiving user input regarding a desired training program or throwing pattern, the ball machine control module 222 can send instructions or commands to the ball throwing machine 10. A processor or other circuitry in the ball throwing machine 10 (such as the control unit 46) can receive and execute these instructions. The ball machine control module 222 can therefore enable a user to control any functions of the ball throwing machine 10, including but not limited to ball velocity, ball delivery (e.g., air, ground, line, lob, or bounce), ball trajectory (e.g., angled, curved, or straight), ball oscillation (e.g., side-to-side or middle-to-side), ball throwing frequency (e.g., every user-specified number of seconds), and the like. The training module 224 can provide functionality for a user to record data regarding the player's usage of the ball throwing machine 10. For example, the training module 224 may provide a training user interface that enables a user to record this player training data (see, e.g., The safety module 226 can provide a user interface that enables users to manage safe use of the ball throwing machine 10. For instance, the safety module 226 can provide parental controls or the like that enable a parent, coach, or other responsible person to manage access to the ball throwing machine 10 or features thereof. It can be desirable to have such features to prevent accidents that can occur, for example, from setting the ball velocity or throwing frequency too high for younger players. These parental controls can include an authentication mechanism (such as a username/password or other credential) for enabling access to the machine 10, control over ball-throwing parameters such as velocity, and an idle or timeout feature that can shut down the controller 220 and/or ball throwing machine 10 after a timeout period of inactivity (such as 30 seconds, a minute, or some other time). Any of these safety features can also be implemented directly in the electronics of the ball throwing machine 10, rather than in the controller 220. The soccer network application 260 can store player training data received from the training module 224 in a data repository 270. The data repository 270 can include any form of physical computer data storage, as well as logical computer storage. For instance, the data repository 270 can include one or more databases, associated physical storage media, and the like. The soccer network application 260 can include hardware and/or software for providing players (via the controllers 220 or other devices), coaches, and recruiters with access to the player training data, among optionally other data and features. The soccer network application 260 includes, in the depicted embodiment, a coaching module 262, a social network module 264, and a recruiting module 266. These modules represent at least some of the functionality that the soccer network application 260 may provide to players, coaches, recruiters, and others. Each of the modules 262, 264, 266 can provide user interfaces for users to access features of the modules 262, 264, 266. For instance, the coaching module 262 can provide one or more user interfaces that enable a coach to access and analyze player training data for a plurality of players associated with that coach. If the player training data includes video, for instance, the coaching module 262 can provide functionality for the coach to view videos of players. The coaching module 262 can also provide functionality through one or more user interfaces for a coach to provide feedback to players. This feedback may be in the form of textual feedback, video feedback, or training program feedback. A coach may, for instance, respond to the uploading of a player's training data with comments on the player's form and suggest adjustments to the player's training program. Beneficially, in some embodiments, the coaching module 262 also enables a coach to select or create a training program to provide to a player as homework or the like. The coaching module 262 may provide a user interface for creating a custom training program for a specific player (see Moreover, the coaching module 262 can enable a coach to better leverage his or her time when training players. In the past, a coach has typically spent a few hours per week with an entire team of players, and the coach's ability to provide individual attention to those players has been limited. Further, a coach is typically not present when a player is practicing at home or with friends. However, with the soccer network application 260, a coach can evaluate player training data for several players and provide individualized feedback and training program recommendations to those players, without leaving his or her home. Thus, the soccer network application 260 can enable coaches to focus more individual attention on the development of players' ball control and trapping skills. The social networking module 264 can provide functionality for different players, coaches, and the like to interact together in an online soccer community. For example, the social networking module 264 can provide user interfaces for creating player or coach pages, discussing soccer training with teammates and friends, uploading pictures and video, linking to web sites regarding soccer or other topics, and other features that may be found in any social network. Generally, the social network provided by the social networking module 264 can enable users to keep track of each other's progress in training with the ball throwing machine 10 and encourage each other in their progress. The social network module 264 may also provide an event user interface that enables users to coordinate events, such as impromptu soccer games, among other features. The recruiting module 266 can provide a recruiting user interface that enables recruiters to examiner player data and/or for players or coaches to upload player data to recruiters. Some examples of recruiters that can use such features include high school recruiters, college recruiters, and professional recruiters. In one embodiment, the recruiting user interface enables recruiters to view player training data obtained with respect to the ball throwing machine 10. Advantageously, in certain embodiments, player training data obtained in conjunction with the ball throwing machine 10 can provide a standardized approach to reviewing player performance. Other player data may also be stored in the data repository 270 and made available to recruiters via the recruiting user interfaces, such as in-game data, coach reviews, scout reports, and the like. It should be noted that the soccer network application 260 can be implemented as one or more physical servers. These servers may be geographically dispersed or co-located. In addition, in some embodiments, the soccer network application 260 is implemented as a cloud-computing platform. For example, the soccer network application 260 can be implemented as one of a plurality of virtual machines executing on a hypervisor, which can be a thin layer of software executing on a physical machine. Accordingly, the modules 262, 264, 266 of the soccer network application 260 can be implemented in hardware and/or softwa re. Further, it should be noted that although the features of The process 300 begins at block 302, where the ball machine control module 222 of the controller 220 establishes communication with a ball throwing device. The ball machine control module 222 can establish communication in one embodiment according to a wireless or other network protocol. At block 304, the ball machine control module 222 causes the ball throwing machine to perform an initial training program. The performance of this initial training program is described in more detail below with respect to At block 306, the training module 224 of the controller 220 records playing training data. There are many ways that this training data may be recorded, and many possible forms that the training data may take. Player training data can be recorded by the training module 224 automatically in one embodiment. For example, the training module 224 can log the commands issued by the controller 220 to the ball throwing machine, or may log the commands actually executed by the machine. For instance, the machine can report to the controller 220 which commands executed successfully and which did not execute successfully. Successful execution of a command can mean, in one embodiment, that the ball throwing machine performed a throw. The amount of data that the training module 224 collects regarding issued or executed commands can vary as well. This data can include characteristics of a throw, such as the ball's velocity (or desired velocity), delivery (or desired delivery), trajectory (or desired trajectory), oscillation (or desired oscillation), and/or frequency (or desired frequency). Any subset of this information may be collected and stored by the training module 224 in computer storage. Alternatively, the training module 224 merely records that a throw command was issued or occurred. In yet another implementation, the training module 224 records the target area or target zone on the player's body that the throw is aimed at (see As described above, the training module 224 may provide a user interface or voice recognition that enables a user to record whether a trap was successful. The player training data may include this success/lack of success information in addition to, or instead of, the more detailed throw or ball characteristics described above. In some embodiments, the training module 224 obtains an electronic indication of whether a player successfully trapped a ball or at least came in contact with the ball. This electronic indication can come from one or more sensors embedded in or placed on a players' clothing. Sensors can be placed or embedded anywhere on or in a player's clothing or on a player's person. Some example areas where sensors may be placed include the chest area, legs, thighs, feet, on the player's head, or any other location on the player's clothing or body. The sensors can be pressure sensors, contact sensors, or any other form of sensor that can produce an electronic output responsive to contact with a ball. For example, a player's shoe may have sensors embedded in one or more surfaces of the shoe to track whether the ball came into contact with such surfaces. Further, in some implementations sensors may be placed in a goal net (and/or on the posts) to determine whether the player has shot a ball in the goal. The sensors may communicate wirelessly with the controller 220 and/or ball throwing machine to provide sensor data to the training module 224. The training module 224 can incorporate the raw sensor data or processed versions thereof into the player training data. Accordingly, the player training data can include automatic indications of whether a trap was successful, or at least whether the ball came into contact with a player. One or more sensors can also be embedded in any of the balls described herein to track trapping, shooting, and other soccer skills. The player training data may also include video data as described above. Further, the training module 224 can record any subset of the training data described herein. At block 308, the training module 224 submits the player training data to the soccer network application 260 with a request for feedback from a coach. This request for feedback may be explicit or implicit. For instance, a player can access a feature of the training module 224 that enables submission of player training data to the soccer network application 260. The soccer network application 260 may in turn make this player training data available to a coach of the player, or to a pool of coaches from which one is assigned or who picks the player training data for analysis. In another example scenario, the player can explicitly request the feedback of a particular coach when submitting the player training data to the soccer network application 260. At block 310, the training module 224 receives a customized training program from the coach through the soccer network application 260. The customized training program can have any characteristics of any of the training programs herein. In one embodiment, the customized training program received includes a set of commands that the ball machine control module 222 can transmit to the ball control machine. In another embodiment, the coach can provide textual, verbal, or video instructions to the player regarding how to customize the player's training. The coach may also provide both an actual training program (including drills or machine commands) and textual, verbal, and/or video feedback. It should be understood, however, that the coach may not actually provide machine-level commands to the controller 220 (although this can be done in some embodiments). Rather, the soccer network application 260 can provide one or more user interfaces that enable a coach to select or define a training program having one or more drills. In response to that selection or definition, the soccer network application 260 can generate the appropriate commands that can be executed on the ball throwing machine. At block 312, the ball machine control module 222 causes the ball throwing device to perform the customized training program. Thus, the ball machine control process 300 can enable a player to receive individualized attention from a remote coach on ball trapping skills or other soccer skills. At block 402, the ball machine control module 222 receives a user selection of training mode. A variety of training modes may be provided. These training modes may include, for example, the ability to access a stored program (or a program over a network), and the ability to perform custom training. This custom training can be a "free-play" type of training, where a user can define each ball's throwing characteristics as they are thrown. Although not shown, a random play mode is also available in some implementations, enabling a user to select a random series of throws having random characteristics (such as random velocity, angle, trajectory, and so forth). The custom training can also involve the user creating his or her own training program, which the user may subsequently store in memory of the controller 220 or ball throwing machine. The controller 220 may also provide functionality (such as a user interface or user interface control) for users to uploads custom training programs created with the controller 220 to the soccer network application 260, where other players or coaches can download the custom training programs. Further, the soccer network application 260 can provide user interface options to comment on and/or rate custom training programs, thereby enabling users to better decide which custom training programs to download. At decision block 402, the ball machine control module 222 determines whether the user selection is for a stored program or custom commands. If the selection was for a stored program, the ball machine control module 222 accesses the stored program at block 406. The stored program may be a program created by the user and saved as a "favorite" program or the like. Alternatively, the stored program can be a training program provided by a coach. If the user selection was for a custom program, the ball machine control module 222 receives a user selection of custom commands at block 408. The ball machine control module 222 of the controller 220 sends the commands to the ball throwing device at block 410, which executes the commands at block 412. At block 502, the coaching module 262 receives player training data from a plurality of controllers of ball throwing machines, such as any of the controllers or machines described above. At block 504, the coaching module 262 electronically generates a remote coaching interface having options for selecting or defining training programs (see Referring specifically to More particularly, in one embodiment, selection of a foot target zone can cause the machine to throw a ball along the ground, or lob the ball toward the player's feet. The distance or approximate distance of the player to the machine may be input by a user into the controller 220 to thereby enable the machine to make such a lob. Similarly, selection of a thigh or chest target zone can cause the controller 220 can cause the machine to lob, bounce, or line drive the ball to a player's thigh or chest. The controller 220 may also provide functionality for other target zones to be selected, such as the head or the hands (for goalies). For example, the controller 220 can enable a player to select a spot away from the player where the player is to dive and catch the ball with his or her hands. In In Referring to The example player training data 1140 shown includes data regarding the most recent session the player had with the ball throwing machine. This data includes trap completion data 1144 and video 1146. A button link 1148 to previous sessions is also provided. The curriculum selection display 1120 includes various controls 1122, 1124 that enable a coach to define a training program. These controls include a selection control 1122 for selecting a stored (e.g., previously-created) program and creation controls 1124 for creating a custom program. Some example parameters for creating a custom program are depicted with respect to the controls 1124, enabling a coach to define for each ball in a program its various characteristics (such as ball delivery type, velocity, oscillation, etc.). These characteristics are merely examples. In other embodiments, for instance, the coaching user interface 1100 may provide functionality for a coach to input the types of target zones each ball is directed to, such as the thigh, chest, foot, etc., in addition to or instead of the characteristics shown. Turning now to As shown, the hopper 330 is a gravity-type hopper with a spiraling ramp 332 located around an internal tube 334. The illustrated hopper 330 has a modular construction to allow for the size of the hopper to be increased or decreased as desired or needed. Thus, a hopper 330 can be made up of one or more hopper sections 330a, 330b. In some embodiments, each hopper section is identical, while in other embodiments there are two or more types of hopper sections. For example, In some embodiments, an end cap 330c can be integrally formed with the end section 330b. The end cap can mark the beginning of the spiraling ramp 332. Balls can be placed on the ramp at the end section 330b, such as near the end cap, to load or reload the hopper. In addition, in some embodiments the end cap 330c of the end section 330b can be removable and can attach to a standard section 330a to form an end section 330b. The standard section 330a is shown with a projecting flange 336 at the top of the spiral that can receive a bottom edge 338 of a hopper section positioned above it. For example, an end section 330b can be placed on a standard section 330a with the bottom edge 338 of the end section 330b resting on the flange 336. This can help ensure proper alignment of the sections while also ensuring smooth rolling of balls between hopper sections. Each spiral ramp 332 can be connected to a support section 334. For example the spiral ramp 332 and support section can be connected with adhesive, fasteners, friction fit, key and channel, etc. In still other embodiments the support section 334 can be integrally formed with the spiral ramp. The support section 334 can be used to impart structural strength to the hopper and can also provide appropriate spacing such that balls within the hopper are able to properly rotate and move downward in the hopper. As illustrated, the support section 334 is in the form of a tube. Tubes can provide structural support and can allow for simple stackability between hopper sections. The hopper sections, each with spiral ramp 332 and tube 334, can connect in one of many different ways to form an assembled hopper 330. For example, two or more tubes 334 can connect via a friction fit, loose fit, fasteners, key and channel, etc. In addition, the tubes may include a locking mechanism to prevent rotation and/or movement in one or more directions. When connected, the two tubes may also align the spiral ramps 332 to form an essentially continuous ramp as has been described. In some embodiments an alignment system can include a notch 350 and a corresponding protrusion 348 that can be used to align the hopper sections. The protrusion 348 on one hopper section can fit within the notch 350 on a second hopper section. As shown, each tube 334 includes a protrusion 348 near the top and a notch 350 near the bottom of the tube. In this way, each tube may be positioned below or above another tube and provide proper alignment for the ramps and for the hopper sections generally. It will be understood that one or more of a number of different alignment systems can be used. As shown the tube 334 is substantially cylindrical, though the tubes can also have other shapes such as conical, pyramidal, and elliptical. In some embodiments the shape of the tube itself can be part of an alignment system and/or locking mechanism. For example, an elliptical tube can be limited to two connecting positions, where one position may not work because of the position of the ramp. In addition, an elliptical tube can prevent rotation of the tube in the x and y directions where z defines the vertical axis. Some embodiments can include a latch to secure the tubes together and to prevent separation absent a corresponding active step to unlatch the tubes. The latch can be part of both the alignment system and the locking mechanism. It can be seen that each tube 334 can include a handle 340 that can allow for simple control of the hopper section, as well as to control placement on and/or removal from a ball throwing machine. Having a modular hopper 330 with stackable hopper sections can allow the size of the hopper to be increased or decreased to adjust capacity as needed. This adjustable capacity can benefit users in many ways. For example, a purchaser can have the option to determine the size hopper to be used and may not be forced into a one size fits all scenario. Additional hopper sections can be purchased at a later time if desired. In addition, a team or coach may desire to use a large number of balls at a training facility or home field, but only a limited number when off site or on the road. The ball throwing machine with the desired number of hopper sections can be used in both cases. This can allow coaches and teams to have greater flexibility in training, warming up, testing, etc. The spiraling ramp 332 and the ball throwing machine can be designed for use with more than one ball size or type. For example, a coach may be involved with a youth team and with an adult team and the coach may therefore desire to use different sized balls for the different teams. As another example, a player using a single ball throwing machine may use small balls when training and larger balls when warming up for a game. As has been mentioned, using a smaller than regulation soccer ball provides many benefits including enabling more effective training of ball handling skills. At the same time, there are times when it will be desirable to use a regulation sized soccer ball. The spiraling ramp 332 of The two ridges 352 can be used with a variety of different sized balls. For example, the ball shown can represent a size 3 ball that only rides on the two rails. A smaller ball, such as a size 1 ball, can use the two rails 352 and a bottom surface, ridge, or rail 354. In other embodiments, the ball shown can represent a size 5 ball and a size 3 ball may use the same two rails 352, or the two rails plus the bottom rail 354. An even smaller ball, such as a size 1 ball, can also use all three rails in some embodiments. In an embodiment with five rails, a size 5 ball can use the two top most rails, while the size 3 ball can use the next two rails down and the size one ball can use these two rails together with a bottom rail. To provide a smooth rolling surface, it may be desirable to have the ridges engage the ball somewhere in the bottom 1/3 or ¼ of the ball. A two/three rail system is shown, though total of two rails, four rails, five rails, or even six rails could be used. Each pair, or is some instances group or three rails could be used to service a single size of ball or multiple relatively similar sizes of balls. Another feature of certain embodiments, including that shown is a high sidewall 356 that can advantageously prevent balls from coming out along the sides of the hopper. In such an embodiment, balls can be added and/or removed from the top or bottom of the hopper but cannot be removed and cannot fall out at other locations. This can also help provide a smooth rolling surface because the sidewalls can be used to guide the movement of the balls to prevent them from traveling in undesired directions or in ways that might create clogs in the system. The sidewall 356 can be sized such that the smallest ball designed to be used in the system cannot pass through the gap 358 formed between the sidewall 356 and the corresponding bottom of the ramp 332 directly above it. Many other variations than those described herein will be apparent from this disclosure. For example, depending on the embodiment, certain acts, events, or functions of any of the algorithms described herein can be performed in a different sequence, can be added, merged, or left out all together (e.g., not all described acts or events are necessary for the practice of the algorithms).
