The science behind a successful baseball swing is complex, taking into account many factors. Often bat speed or a combination of bat speed and swing plane are used to analyze a player's swing. Information regarding the kinetics of the player's body during the swing is generally only available by repeated and careful video analysis. Even then, the results are imprecise and depend on the skill of the player or hitting coach to spot and properly analyze problem areas. The system of the present disclosure allows one to obtain precisely measured data that demonstrates the kinetics of a player's body during a swing. This data may be used in a variety of ways in order to help a player recognize one or more problem areas and thereby develop a more successful swing. This data may also be used in scouting baseball players, such as by providing data concerning the kinetics of a player's body during a swing and/or the consistency of a player's body movement throughout multiple swings.
Embodiments of the present disclosure relate to a garment, such as a shirt, that is configured for analyzing a wearer's baseball swing. The garment contains a plurality of sensors including (1) a wrist sensor that is configured to detect the motion of a wearer's wrist or hand during the swinging motion, (2) a shoulder sensor that is configured to detect the motion of a wearer's shoulder during the swinging motion, and (3) a hip sensor that is configured to detect the motion of a wearer's hip during the swinging motion. In some embodiments, these are the only three sensors present in the garment. In other embodiments, the garment may also include additional sensors. The garment also includes a wireless transmitter that is configured to transmit the data from the plurality of sensors to an external processing and/or display unit.
In some embodiments of the garment, the plurality of sensors may be connected to one another and to the wireless transmitter through a flexible ribbon. The data from the plurality of sensors may be conveyed to the wireless transmitter through the flexible ribbon. The flexible ribbon is desirably incorporated into the garment so as not to interfere with the wearer's motion. For example, in some embodiments the flexible ribbon may extend through a tunnel that is formed into the fabric of the garment. The sensors are desirably of a sufficiently small size so as not to interfere with the wearer's motion. Indeed, in some embodiments the sensors may be of a sufficiently small size that a wearer would not notice their presence during the swinging motion. For example, each sensor may desirably be less than one inch by one inch and have a thickness that is less than one-quarter of an inch. The sensors are also desirably not visible on the exterior of the garment. For example, in some embodiments the garment may have the outward appearance of being a standard or high-performance shirt. For example, the garment may be a high-performance training shirt, a compression undergarment that is designed to be worn under a baseball jersey, a baseball jersey, or the like.
In some embodiments, one or more of the sensors are irremovably incorporated into the garment. For example, each of the plurality of sensors may be irremovably incorporated into the garment. Alternatively, each of the wrist sensor and shoulder sensor may be irremovably incorporated in the garment and the hip sensor may be removable (such as by being incorporated into a removable control module). The irremovably incorporated sensors are desirably incorporated in a manner that allows the garment to be machine-washable without damaging the sensors.
In some embodiments, the garment includes a control module. The control module may include, for example, the wireless transmitter, a power source, a charging port, an on-off switch, and the like. Desirably, the control module may easily be attached to the garment and connected with the plurality of sensors. For example, in some embodiments the garment may comprise a pocket, such as an internal pocket, that is configured to hold the control module. The pocket may be located at a position by which it may easily be linked with the plurality of sensors, such as by plugging one end of a flexible ribbon that connects the sensors into the control unit. For example, the pocket may be located at a wearer's hip or lower back.
Embodiments of the present disclosure also relate to a system for analyzing a user's baseball swing. The system includes a garment such as any of those described herein, a processor configured to convert the raw data from the plurality of sensors into user swing information, and a display configured for displaying the user swing information. In some embodiments, the processor and display may be components of a personal computer, such as a desktop or laptop computer, or of a mobile device, such as a smartphone or tablet.
In some embodiments, the user swing information may comprise any of a number of different swing metrics. For example, the user swing information may include a user's swing plane; hand speed; swing acceleration; maximum acceleration; hit angle; bat speed; time in the strike zone; hit point; information regarding the relative timing of hip, shoulder, and/or wrist movements; or combinations thereof. The user swing information may be displayed in any number of ways, including for example graphically, with animations, by comparison to a control or target swing, and the like. In some embodiments, the system may be configured to store and compare user swing information from multiple swings, such as swings from one or more training sessions. The system may also be configured to share user swing information, such as over the Internet.
In some embodiments, the system may be configured to have multiple modes, with the user swing information that is displayed in each mode being different. For example, the system may include a first mode and a second mode, with the user swing information that is selectable in the first mode being different from the user swing information that is selectable in the second mode. The first mode may be streamlined to provide basic, easy to use swing metrics, such as the type that may be immediately incorporated into a user's training session. The second mode may provide more advanced swing metrics and analytics that may be used to analyze a user's swing over time.
Embodiments of the present disclosure also relate to a method for analyzing a user's baseball swing. The method involves providing a garment such as any of those disclosed herein; causing a user to wear the garment while performing a baseball swing; and transmitting the data from the plurality of sensors to an external unit, where the raw data is processed into user swing information and the user swing information is displayed. In some embodiments, the user swing information may comprise any of a number of different swing metrics. For example, the user swing information may include a user's swing plane; hand speed; swing acceleration; maximum acceleration; hit angle; bat speed; time in the strike zone; hit point; information regarding the relative timing of hip, shoulder, and/or wrist movements; or combinations thereof. The user swing information may be displayed in any number of ways, including for example graphically, with animations, by comparison to a control swing, and the like. In some embodiments the external unit may be positioned so that it can be viewed by a user without requiring the user to step out of a batter's box.
A clear conception of the advantages and features of one or more embodiments will become more readily apparent by reference to the exemplary, and therefore non-limiting, embodiments illustrated in the drawings:
Reference will now be made in detail to certain embodiment(s), examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals will be used throughout the drawings to refer to the same or like parts.
An embodiment of the garment 10 is shown in
In other, non-illustrated embodiments, the garment 10 may comprise one or more additional sensors. For example, in some embodiments, the garment may comprise an additional wrist sensor 11, providing a garment that includes a sensor at each of a wearer's wrists. In some embodiments, the garment 10 may comprise an additional shoulder sensor 12 so that the garment includes a sensor at each of a wearer's shoulder. And in some embodiments, the garment 10 may comprise an additional hip sensor 13 so that the garment includes a sensor at each of a wearer's hips. Any of these additional sensors may be provided in order to increase the amount of raw data that may be used in calculating user swing information. Alternatively, one or more of these additional sensors may be provided in order to provide a garment 10 that is configured for use by a switch-hitter or by multiple users, such as a user that batted from the right side and a user that batted from the left side.
Additional sensors located elsewhere on the garment are also contemplated for use with the presently disclosed garment. However, the inventors have found that the combination of wrist sensor 11, shoulder sensor 12, and hip sensor 13 provides all of the necessary information from which an array of useful swing information may be calculated. Accordingly, by placing sensors only at these three locations, embodiments of the garments 10 of the present disclosure may be cost-effectively produced and provide a level of wearer comfort that may be unattainable with larger numbers of sensors.
Although the embodiment illustrated in
Each sensor may be configured to detect, and in some embodiments measure, a variety of motions across numerous planes. For example, each sensor may comprise one or more accelerometers and/or one or more gyroscopes. Each sensor may also comprise one or more magnetometers. For instance, each sensor may include an inertial measurement unit (IMU). In some embodiments, the IMU may be a three-axis IMU, which comprises three accelerometers, three gyroscopes, and optionally three magnetometers. Each component on the sensor may be mounted to a printed circuit board (PCB).
Each sensor may either be incorporated into the garment in a manner that allows one to detach the sensor from the garment, i.e. removably incorporated into the garment, or in such a way that the sensor is not intended to be detached from the garment, i.e. irremovably incorporated into the garment. For example, one or more of the plurality of sensors may be irremovably incorporated into the garment by being sewn into the garment. In some embodiments, each of the plurality of sensors may be irremovably incorporated into the garment. In some embodiments, such as the embodiment illustrated in
Where the garment 10 contains one or more irremovably incorporated sensors, it is also desirable that the garment 10 be configured so as to be washable without damaging the sensors. For example, in some embodiments the garment 10 is configured so as to be machine-washable without causing damage to the one or more irremovably incorporated sensors. For example, the sensor, including any connection points, may be coated with a waterproof material, such as a waterproof epoxy. In some embodiments where one or more of the sensors are electrically connected to a flexible ribbon, as will be subsequently described in greater detail, the sensor and its point or points of connection with the flexible ribbon are coated with a waterproof epoxy. Optionally, the coated sensor and its connection point(s) may also be provided with a reinforcing layer, such as a vulcanized silicone. The inclusion of a reinforcement layer may provide an added layer of stress protection to the connections point(s) and the wire exits.
In some embodiments, each of the sensors is desirably configured so as to be substantially unnoticeable to a wearer, especially during a swinging motion. For example, each of the plurality of sensors may have a thickness that is less than one-half of an inch, alternatively less than one-quarter of an inch. Each sensor may also desirably be sized at one inch by one inch or less. Through careful selection and placement of the sensors, embodiments of the garment 10 serve to integrate technology into a garment in a way that is substantially unnoticeable to the wearer.
The garment 10 also desirably comprises a wireless transmitter 14 that is configured to transmit the data collected by the plurality of sensors to an external unit. The wireless transmitter 14 may be positioned anywhere on the garment. The wireless transmitter 14 is desirably positioned at a location where it will not interfere with the wearer's swinging motion. In some embodiments, such as that illustrated in
In some embodiments, the sensors are connected to the wireless transmitter 14 or the control module 15, and optionally to one another, through a flexible ribbon 16. An embodiment of the flexible ribbon 16 is shown in
The flexible ribbon 16 is desirably of sufficient thinness so that it will not be felt by a wearer of the garment 10. For example, the flexible ribbon 16 may be less than one-quarter of an inch thick, alternatively less than one-eighth of an inch thick, alternatively less than one-twelfth of an inch thick, alternatively less than one-sixteenth of an inch thick. The width of the flexible ribbon 16 may vary. In some embodiments, the flexible ribbon may have a width that is less than one-third of an inch, alternatively less than one-quarter of an inch. The length and positioning of the flexible ribbon 16 is determined by the arrangement of the plurality of sensors and the size of the garment 10 into which the sensors and ribbon are incorporated.
For example, in the embodiment that is illustrated in
In an alternative embodiment, the hip sensor 13 may also be irremovably incorporated into the garment 10. Accordingly, the flexible ribbon 16 may also comprise a third portion that is configured to connect the hip sensor 13 with the control module 15, which may be located elsewhere on the garment, such as at a position that corresponds with the lower back of a wearer. In this embodiment, the second portion 18 may be configured to connect the shoulder sensor 12 with either of the hip sensor 13 or the control module 15. In other embodiments, such as where one or more additional sensors may be included in the garment 10, the flexible ribbon 16 may take on any number of different configurations and include any number of portions.
In some embodiments, the flexible ribbon 16 may be configured to removably connect with a control module 15. For example, the flexible ribbon 16 may comprise a connector 19 that is configured to link to a control module 15. The connector 19 may take on any number of formats, so long as it is capable of securely connecting with the control module 15. In the embodiment shown in
The flexible ribbon 16 may be incorporated into the garment 10 in any number of ways. In some embodiments, for example, the garment may comprise a tunnel through which the flexible ribbon extends. The tunnel may be sewn into the garment in a manner so as to be flush with the rest of the interior of the garment, rendering the flexible ribbon 16 substantially unnoticeable to a wearer. In some embodiments, the flexible ribbon 16 may be sewn into the garment.
Embodiments of the garment 10 also comprise a control module 15. As previously described, in some embodiments the control module 15 may comprise the wireless transmitter 14, the hip sensor 13, or both. The control module 15 may also comprise a power source for the sensors, such as a rechargeable battery. The control module 15 may also comprise a port by which the power source may be charged, such as through connection of a charging cable. The control module may also comprise a power switch, by which the control module may be switched between “on” and “off” settings. The control module 15 may also comprise an indicator, such as a light, that indicates whether the control module is “on” or “off”. In some embodiments, the control module 15 may include one or more processors, which may be configured to process the data from the plurality of sensors prior to wireless transmission.
The control module 15 may be removably or irremovably incorporated into the garment 10. In some embodiments, the control module 15 is desirably removably incorporated into the garment 10. For example, in some embodiments, the garment 10 may comprise a pocket 20 into which the control module may be placed. The pocket 20 may be located on the interior of the garment 10 at a variety of positions. For example, in the embodiment shown in
In some embodiments, for example where it may be desirable to showcase the technology, the control module 15 may be located at an exterior position on the garment 10. Accordingly, embodiments of the garment 10 may comprise a connector 19 on the exterior of the garment. For instance, the garment 10 may comprise a snap-secure connector 19 at a desired location on the exterior of the garment, to which the control module 15 may be affixed. In this way, one may securely affix the control module 15 to the garment 10 simply by attaching it to the exterior connector 19. The location of the exterior connector 19 on the garment 10 may vary. For example, the exterior connector 19 may be located at a location on the garment 10 that corresponds with the hip of the wearer, alternatively a location that corresponds with the lower back of the wearer, etc.
In some embodiments, the garment 10 of the present disclosure is designed to fit tightly against the skin of the wearer so as to ensure accurate and precise readings from the plurality of sensors. For example, the garment 10 may be made of a stretchable, optionally high-performance fabric. A high-performance shirt is configured to provide moisture wicking, stretch, and breathability properties that are of particular benefit during athletic training. High performance shirts may be made from a blend of polyester and spandex, such as a blend of about 92% Polyester and about 8% Spandex. In some embodiments, the garment 10 is configured so that the plurality of sensors, as well as other elements that may be present (such as a control module 15 and/or flexible ribbon 16), are not visible on the exterior of the garment. This desirably provides the garment 10 with the outward appearance of being, for example, a conventional high-performance garment, such as that illustrated in
In some embodiments, the garment 10 of the present disclosure may comprise a baseball jersey. Baseball jerseys, however, are conventionally short-sleeved and thus lack a location for the wrist sensor 11. Accordingly, in some embodiments, such as that illustrated in
In other embodiments, the garment 10 may be short-sleeved. For example, in some embodiments, the garment 10 may be a short-sleeved garment made of a stretchable, optionally high-performance fabric. In other embodiments, the garment 10 may have the outward appearance of a conventional baseball jersey. For example, as in the embodiment illustrated in
In these embodiments where the garment 10 is short-sleeved, the wrist sensor 11 may not be incorporated into the garment. Rather, the wrist sensor 11 may be configured to be worn on a user's wrist. For example, the wrist sensor 11 may be incorporated into a wristband 23. Where the wrist sensor 11 is not incorporated into the garment, it should be configured to communicate either (a) directly with an external unit, e.g. the same external unit to which the wireless transmitter 14 is configured to communication, or (b) the control module 15. The wrist sensor 11 may thus be operably connected to its own wireless transmitter 24 (which for example may also be incorporated into a wristband 23). The type of wireless communication technology that is employed by the wireless transmitter 24 is not limited and may be selected from those generally known in the art, such as Wi-Fi, Bluetooth or other radio wave-based wireless, induction wireless, infrared wireless, ultra wideband (UWB), or the like.
It should also be understood that in those embodiments where the wrist sensor 11 is configured to communicate with the control module 15, the control module may comprise a wireless receiver. In some embodiments, for example, it may be desirable for the wireless transmitter 24 associated with the wrist sensor 11 to communicate the sensor data to the control module 15 via a short-range wireless technology such as Bluetooth or the like. At the same time, it may be desirable for the wireless transmitter 14 associated with the control module 15 to transmit the data from the plurality of sensors (or in some embodiments the processed data) to an external unit using a longer-range wireless technology, such as Wi-Fi or the like.
The above-described embodiments are exemplary and non-limiting. It will be appreciated that other garment types, designs, and styles are also suitable for use with the invention described herein.
The present disclosure also relates to a system 100 for analyzing a user's baseball swing. The system 100 comprises the garment 10 according to any of the embodiments described above. The system 100 also comprises an external unit 30. The external unit 30 may be configured to receive the wireless transmission of sensor data from the wireless transmitter 14, process that sensor data to convert it into user swing information, and then display the user swing information.
Accordingly, the external unit 30 generally comprises a display 31 that is configured to display the user swing information. The external unit 30 also typically comprises a processor that is configured to convert the data from the plurality of sensors into user swing information. In some embodiments, the processor may be incorporated into the garment 10, such as for example by inclusion of a processor in the control module 15. More desirably, however, the processor is located in the external unit 30. The external unit 30 may also comprise more than one component. For example, the component comprising the display 31 may be separate from the component comprising the processor.
In some embodiments, the external unit 30 may comprise a personal computer, such as a laptop computer or a desktop computer. Alternatively, the external unit 30 may comprise a handheld device, such as a smartphone or tablet computer. In each of these embodiments, the device that serves as the external unit 30 comprises a built-in processor and screen (display). Accordingly, the system 100 may also comprise a program or “app” that is configured to cause the processor to convert the data from the plurality of sensors into swing information and to display the swing information on the screen of the device. In alternative embodiments, the system may comprise a stand-alone external unit 30 that is specially configured for processing data from the sensors and displaying user swing information.
According to embodiments of the present disclosure, the system 100 may comprise one or more garments 10, one or more external units 30, or both. For example, in some embodiments, the system 100 may be configured so that an individual, such as a hitting coach, could simultaneously track the swings of multiple batters, each wearing a garment 10 in accordance with the above disclosure, on a single external unit 30. Alternatively, sensor data from a single garment 10 could be transmitted to multiple external units 30 so that multiple individuals could analyze a batter's swing, scout the batter, or the like.
The user swing information may comprise any of a variety of swing metrics, parameters, and the like. Individual types of swing information are described in more detail below. It is contemplated that the system 100 may be configured to compute any variety of swing information, including combinations of the types of swing information specifically described below, as well as types of swing information not specifically described.
In some embodiments, the system 100 may be configured to compute and display a user's swing plane or swing path. Swing plane information identifies, for example, whether the user's swing was characterized by a downward motion, an upward motion, or the maintenance of a level plane. The swing plane of a batter's swing is closely related to what type of contact the player makes with the ball and whether that contact is likely to result in a groundball, fly ball, or line drive. In the embodiments of the system 100 illustrated in
In some embodiments, the system 100 may be configured to compute and display a user's hand speed. Hand speed information relates, for example, to the speed with which a batter gets the bat through the strike zone, as well as to the strength of the contact made by the batter. In the embodiments of the system illustrated in
In some embodiments, the system 100 may be configured to compute and display information relating to the timing of the batter's hand (or hands), shoulder (or shoulders), and hip (or hips). A good baseball swing requires that the batter's hands, shoulders, and hips all work in conjunction with one another to produce a desired motion of the baseball bat and to create power as the batter moves the baseball bat through the strike zone. Accordingly, information regarding the movement of these body parts relative to one another may be of significant value in the analysis of a baseball swing and of a batter's consistent ability to repeat a swing. For example, the system 100 may provide information as to whether a batter's shoulder movement was late in comparison to the batter's hands, whether a batter's hips were early in comparison to the batter's shoulder, and the like.
In the embodiment of the system illustrated in
In the embodiment of the system illustrated in
In some embodiments, the system 100 may be configured to compute and display information relating to a user's swing acceleration. The overall amount of the acceleration, as well as the acceleration profile, obtained by the batter during a swing provides some indication of how quickly the batter gets the bat into and/or through the strike zone, as well as the power of the swing at the critical point where it makes contact with the ball. In the embodiment of the system illustrated in
In some embodiments, the system 100 may be configured to compute and display a swing rating. The swing rating may be used as a shorthand way for a user to identify the overall quality of the swing, as determined by the system based on the data from the plurality of sensors. In the embodiment of the system 100 illustrated in
In some embodiments, the system 100 may be configured to compute and display bat speed information. The speed of the bat during a swing can be calculated using the data collected by the plurality of sensors and the bat length. Accordingly, in some embodiments, the system 100 may be configured to prompt a user to enter the length of the bat that is used during a swing or series of swings. The system 100 may then calculate the bat speed and that information may be displayed to a user in any of a variety of ways.
In some embodiments, the system 100 may be configured to compute and display information relating to the batter's hit point. Hit point information can be calculated using the data collected by the plurality of sensors and the orientation of the batter with home plate. Accordingly, for example, in some embodiments, the system 100 may also comprise one or more sensors that are configured to orient the user with home plate, e.g. one or more sensors located on or near home plate. Alternatively, a user may be prompted to enter information relating to the batter's stance as it relates to home plate. The system 100 may then calculate hit point information and that information may be displayed to a user in a variety of ways.
In some embodiments, the system 100 may be configured to compute and display information relating to the batter's time in the zone. Time in the zone information could be displayed to a user in any of a variety of ways. For example, this information may include a graphic overlay showing home plate and indicating the time during the swinging motion that the batter would maintain the bat over the plate.
In some embodiments, the system 100 may be configured to display a swing animation, i.e. a simulation of the batter's swing. The animation could be configured to focus the user on certain portions of the batter's swing, such as one or more areas where improvement may be desirable. The animation could also be compared against a control swing, such as a swing by the batter that was deemed of high quality, an idealized version of the user's swing, a programmed target swing, or the like. In some embodiments, the animation could be compared against a target swing that is based on the swing of a professional baseball player to which the batter aspired or was thought to possess a similar swing. In some embodiments, the animation could be compared against a batter's swing from a period of time before certain adjustments were made or before an injury occurred. The system 100 could also be configured to identify differences between the current swing and the prior swing or the target swing, and to provide swing improvement advice based on these differences.
In some embodiments, the system 100 may be configured to identify the expected path of the ball. For example, based on the data from the plurality of sensors, and any other optional data that is input into the system, each swing could be tagged with a hit type (e.g. line drive, grounder, fly ball, etc.), a direction (e.g. left, center, right, foul ball, etc.), and/or a distance that the ball would be expected to travel. This information could be displayed to a user in any of a variety of ways. For example, the system could be configured to display the information to the user with text or visually, such as with an animation.
The system may be configured to display any combination of the above-described swing information and may also include swing information not specifically described herein. The user swing information may also be displayed in any of a variety of ways. In some embodiments, for example, the user swing information is at least partially displayed graphically or with an animation.
In some embodiments, the user swing information from one or more swings may be stored, such as in a memory. For instance, a user may create a training session into which an amount of swing information across a number of swings may be compiled and stored. In some embodiments, therefore, swing information from multiple training sessions may be compared against one another. Because the information is stored, the comparison may be performed, for example, after a training session or at any other time when it is convenient. This may be used, for example, to track the improvement of a user's swing, to track a user's adjustments to the swing in response to certain types of pitches, to accurately compare a user's post-injury swing with the user's pre-injury swing, and the like. In some embodiments, the system may be configured to offer swing improvement advice based on stored swing data.
In some embodiments, the system 100 may be configured to produce or take into account a performance goal. For example, the system may prompt a user to input a performance goal. Alternatively, the system 100 may be configured to develop a performance goal for a user based on the data from the plurality of sensors. The user's swing data may then be compared against the performance goal. The system 100 may also be configured to provide improvement tips based on the performance goal and the swing data.
In some embodiments, the system 100 may be configured to have multiple display modes. For example, in some embodiments, the system 100 may include at least a first mode and second mode, wherein the user swing information that is selectable or displayed in the first mode is different from the user swing information that is selectable or displayed in the second mode. The first mode may provide a streamlined user interface in which basic swing metrics may be easily analyzed by a user. Because it is contemplated that this mode is most likely to be used by a batter, such as during a training session, this mode may be referred to as a “Batter” mode. The second mode may provide a more advanced user interface in which advanced swing metrics may be analyzed. Because it is contemplated that this mode is most likely to be used by a hitting coach, such as after a batter's training session, this mode may be referred to as a “Coach” mode. By way of example, the first or “Batter” mode may display user swing information in a manner such as that shown in
In some embodiments, the system 100 may be configured for the sharing of user swing information, such as over the Internet, e.g. through email, social media, and the like.
The present disclosure also relates to a method for analyzing a user's baseball swing. The method involves having a batter don the garment 10 according to any of the embodiments described above while performing a baseball swing. The garment 10, such as through its wireless transmitter 14, transmits the data from the plurality of sensors to an external unit 30. The data that is transmitted from the plurality of sensors is processed to produce user swing information and the user swing information is displayed in a manner that can be viewed by a user. In alternative embodiments, the processing of the data collected by the plurality of sensors may be performed prior to transmission to the external unit 30, such as by one or more processors incorporated into the control unit 15.
In some embodiments, for example, the external unit 30 may comprise a personal computer, such as a laptop computer or a desktop computer. Alternatively, the external unit 30 may comprise a handheld device, such as a smartphone or tablet computer. In each of these embodiments, the device that serves as the external unit 30 comprises a built-in processor and screen. Accordingly, the method may utilize a program or “app” that is configured to cause the processor to convert the data from the plurality of sensors into swing information and to display the swing information on the screen of the device. In some embodiments, the external unit may be positioned so that the swing information can be viewed by a batter without requiring the batter to step out of the batter's box.
According to embodiments of the present disclosure, the method may make use of one or more garments 10, one or more external units 30, or both. For example, in some embodiments, a hitting coach might simultaneously track the swings of multiple batters, each wearing a garment 10 in accordance with the above disclosure, on a single external unit 30. Alternatively, sensor data from a single garment 10 could be transmitted to multiple external units 30 so that multiple individuals could analyze a batter's swing, scout the batter, or the like.
The user swing information may comprise any of a variety of information. Individual types of swing information are described in more detail below. It is contemplated that the method may be used to provide any variety of swing information, including combinations of the types of swing information provided below, as well as types of swing information not specifically described.
In some embodiments, the method may be used to determine and display a user's swing plane or swing path. Swing plane information identifies, for example, whether the user's swing was characterized by a downward motion, an upward motion, or the maintenance of a level plane. The swing plane of a batter's swing is closely related to what type of contact the player makes with the ball and whether that contact results in a groundball, fly ball, or line drive. In the embodiments illustrated in
In some embodiments, the method may be used to determine and display a user's hand speed. Hand speed information relates, for example, to the speed with which a batter gets the bat through the strike zone and to the strength of the contact made by the batter. In the embodiments illustrated in
In some embodiments, the method may be used to determine and display information relating to the timing of the batter's hand or hands, shoulder or shoulders, and hip or hips. A good baseball swing requires that the batter's hands, shoulders, and hips all work in conjunction with one another to produce a desired motion of the baseball bat and to create power as the baseball bat moves through the strike zone. Accordingly, information regarding the movement of these body parts relative to one another may be of significant value in the analysis of a baseball swing or of a batter's consistent ability to repeat a swing. For example, the method may provide information as to whether a batter's shoulder movement was late in comparison to the batter's hands, whether a batter's hips were early in comparison to the batter's shoulder, and the like.

In some embodiments, the method may be used to determine and display information relating to a user's swing acceleration. The amount and timing of the acceleration obtained by the batter during a swing provides some indication of how quickly the batter gets the bat into and/or through the strike zone, as well as the power of the swing at the critical point where it makes contact with the ball. In the embodiment illustrated in
In some embodiments, the method may be used to determine and a swing rating. The swing rating may be used as a shorthand way for a user to identify the overall quality of the swing, as determined by the system by processing the data from the plurality of sensors. In the embodiment illustrated in
In some embodiments, the method may be used to determine and display bat speed information. The speed of the bat during a swing can be calculated using the data collected by the plurality of sensors and the bat length. Accordingly, in some embodiments, a user may be prompted to enter the length of the bat that is used during a swing or series of swings. The processor may then calculate the bat speed, which information may be displayed to a user in any of a variety of ways.
In some embodiments, the method may be used to determine and display information relating to the batter's hit point. Hit point information can be calculated using the data collected by the plurality of sensors and the orientation of the batter with home plate. Accordingly, for example, in some embodiments, one or more sensors that are configured to orient the user with home plate, e.g. one or more sensors located on home plate, may be used. Alternatively, a user may be prompted to enter information relating to the batter's stance as it relates to home plate. The processor may then calculate hit point information, which information may be displayed to a user in a variety of ways.
In some embodiments, the method may be used to determine and display information relating to the batter's time in the zone. Time in the zone information could be displayed to a user in any of a variety of ways. For example, this information may include a graphic overlay showing home plate and indicating the time during the swinging motion that the batter would maintain the baseball bat over the plate.
In some embodiments, the method may be used to determine and display a swing animation, i.e. a simulation of the batter's swing. The animation could be configured so as to focus the user on certain portions of the batter's swing, such as areas where improvement may be desirable. The animation could also be compared against a control swing, such as a swing by the batter that was deemed of high quality, an idealized target swing, and the like. In some embodiments, the animation could be compared against a target swing that incorporated the swing of a professional baseball player to which the batter aspired or was compared. In some embodiments, the animation could be compared against a batter's swing from a period of time before certain adjustments were made or before an injury occurred. The animation could also be used to identify differences between the current swing and the prior swing or the target swing and to provide swing improvement advice based on these differences.
In some embodiments, the method may be used to determine and the expected path of the ball. For example, based on the data from the plurality of sensors, and any other optional data that is input to the processor, each swing could be tagged with a hit type (e.g. line drive, grounder, fly ball, etc.), a direction (e.g. left, center, right, foul ball, etc.), and/or a distance that the ball would be expected to travel. This information could be displayed to a user in any of a variety of ways. For example, the information could be displayed to the user with text or through an animation.
The method may be used to determine and display any combination of the above-described swing information. Any of the swing information may also be compared with that from a previous swing or with a control or target value. This may, for example, provide an easy way for a user to track his improvement in any certain area or metric over the course of numerous swings or training sessions.
In some embodiments, the user swing information from one or more swings may be stored, such as in a memory. For instance, a user may create a training session into which an amount of swing information across a number of swings may be compiled and stored. In some embodiments, therefore, swing information from multiple swings or multiple training sessions may be compared against one another. The comparison may be performed, for example, after a training session or at any time when convenient. This may be used, for example, to track the improvement of a user's swing, to track a user's adjustments to the swing in response to certain types of pitches, to accurately compare a user's post-injury swing with the user's pre-injury swing, and the like.
In some embodiments, the method may take into account a performance goal. For example, a user may be prompted to input a performance goal. Alternatively, the processor may be configured to develop a performance goal for a user based on the data from the plurality of sensors. The user's swing data may then be compared against the performance goal. Improvement tips based on the performance goal and the swing data may be provided.
In some embodiments, a user may share his or her user swing information, such as over the Internet, e.g. through email, social media, and the like.
