A device constructed in accordance with an embodiment of the present disclosure may include one or more ball impact sensors operationally coupled to one or more tactile feedback components. The sensors may be positionable upon one or more surfaces of a shoe. The device may generate a tactile sensation when one or more sensors detect a ball impact.
This application claims the benefit of U.S. Provisional Application No. 61/831,617, filed Jun. 6, 2013 by the present inventors.
BACKGROUNDThe present disclosure relates to providing immediate feedback to athletes during sports training. Specifically, the disclosure relates to sports that involve kicking a ball. Some examples are soccer, American football, and rugby.
In a kicking sport such as soccer, there may be multiple kicking techniques. Each kicking technique may involve an athlete making contact with a ball using a specific surface of a shoe. However, a novice athlete may tend to make contact with the ball using a suboptimal surface of the shoe.
For example, in soccer, one such kicking technique is called a straight kick. In a straight kick, an athlete kicks a ball with a top surface of a shoe. An amateur athlete may attempt a straight kick but incorrectly strike the ball with a forward tip of the shoe. This may reduce the accuracy and power of the kick. In some cases, this may even cause injury to the athlete.
Many different devices have been proposed to train athletes to kick a ball with specific surfaces of a shoe. Prior devices may provide auditory feedback, visual feedback, or both auditory and visual feedback when an athlete uses an optimal surface of a shoe. Some devices that provide auditory feedback are disclosed in U.S. Pat. No. 4,711,043 (Johnson et. al), U.S. Pat. No. 5,433,437 (Dudley), U.S. Pat. No. 5,897,446 (Krause & Wiseman), and U.S. Pat. No. 6,808,462 (Snyder et. al).
However, auditory feedback may not provide physical reinforcement to aid kinesthetic learning. In other words, auditory feedback may not provide a physical sensation to help an athlete associate his or her method of performing a particular kicking technique with a correct execution of the kicking technique. Additionally, auditory feedback may be problematic in a group training setting. For example, auditory feedback from an athlete's device may confuse or distract other athletes who are practicing nearby.
Likewise, visual feedback may not provide physical reinforcement to aid kinesthetic learning. Additionally, visual feedback near an athlete's foot may encourage the athlete to look down at his or her foot after a kick. Looking down may be distracting and undesirable in many kicking techniques.
SUMMARYTo overcome these deficiencies, a device constructed in accordance with an embodiment of the present disclosure may include one or more ball impact sensors, operationally coupled to one or more tactile feedback components. The sensors may be positionable on one or more surfaces of a shoe. The device may generate a tactile sensation when one or more sensors detect a ball impact.
A device constructed in accordance with another embodiment of the present disclosure may include one or more ball impact sensors, operationally coupled to one or more circuits. The one or more circuits may generate a tactile sensation in response to a ball impact.
In accordance with yet another embodiment of the present disclosure, a method of enhancing performance in kicking sports may include recognizing a ball impact on one or more surfaces of a shoe, producing tactile feedback related to the ball impact, and conveying the tactile feedback to an individual.
A device constructed in accordance with an embodiment of the present disclosure may produce tactile feedback, which may provide several advantages over auditory feedback or visual feedback. Tactile feedback may provide physical reinforcement to aid kinesthetic learning. In other words, tactile feedback may provide a physical sensation to help an athlete associate his or her method of performing a kicking technique with a correct execution of the kicking technique. Furthermore, tactile feedback may enable a discrete training experience, since tactile feedback may only be sensible to the athlete using the device. Additionally, the athlete may maintain concentration because he or she may not need to look down at his or her foot after the kick to receive feedback. Thus, tactile feedback may enhance an athlete's engagement and focus during a practice session.
Assembly 10 may have many variations. Strap 12, strap 13, and pouch 11 may be manufactured with other materials such as leather, canvas, rubber, silicone, or plastic. Alternatively, strap 12, strap 13, and pouch 11 may be made entirely of hook and loop tape. Instead of hook and loop tape, assembly 10 may use snaps, buckles, or clips to create a releasable bond between straps 12 and 13. Alternatively, straps 12 and 13 may be replaced with one or more plastic zip ties or one or more hook and loop cable ties.
To use device 1, an athlete first selects a kicking technique to practice. Then, the athlete attaches device 1 to a shoe, positioning pouch 11 on an optimal surface for the selected kicking technique. Next, the athlete performs the selected kicking technique, making contact with a ball. If the athlete kicks the ball using the optimal surface of the shoe, device 1 provides a tactile sensation as feedback. If the athlete kicks the ball using a suboptimal surface of the shoe, device 1 does not provide tactile feedback. Thus, the athlete is able to determine whether or not he or she executed the selected kicking technique using the optimal surface of the shoe. Without supplementary tactile feedback, the athlete may find it difficult to determine whether or not he or she executed the selected kicking technique using the optimal surface of the shoe.
If the athlete receives tactile feedback from a kick, he or she may attempt to receive tactile feedback from subsequent kicks. In order to continue receiving tactile feedback, the athlete may maintain his or her method of performing the selected kicking technique and may continue to kick the ball with the optimal surface of the shoe. If the athlete does not receive tactile feedback from a kick, he or she may attempt to receive tactile feedback from subsequent kicks. In order to receive tactile feedback, the athlete may modify his or her method of performing the selected kicking technique to use the optimal surface of the shoe. By repeatedly kicking the ball with the optimal surface of the shoe, the athlete may build proficiency in the selected kicking technique.
When an athlete performs a selected kicking technique, the ball may move along a certain flight path. Device 1 may be designed to minimally affect the flight path of the ball. If a device protrudes significantly from a shoe, it may alter the shape of the shoe's contact surfaces with the ball. Altering the shape of the shoe's contact surfaces may undesirably affect the flight path of the ball. Thus, it may be advantageous to minimize the protrusion of device 1 from the shoe. For example, device 1 may be manufactured to protrude no more than 0.75 inches from the shoe. Manufacturing device 1 with flexible materials may aid in minimizing the protrusion of device 1. Additionally, manufacturing device 1 with low-profile electronic components such as pancake-style vibrating motor 43 may further aid in minimizing the protrusion of device 1.

After the momentary contact between pouch 11 and ball 30, the ball no longer depresses tactile switch 41 and the switch changes state from closed back to open. Then, capacitor 45 begins to discharge through resistor 47 into base terminal 46b of transistor 46. This keeps current flowing between collector terminal 46a and emitter terminal 46c of transistor 46 and through vibrating motor 43 for a short duration until capacitor 45 is discharged. This results in a short duration of tactile sensation for the athlete.
Many different circuits with different components than circuit 40 may be designed to produce similar results as circuit 40. For example, instead of using coin cell battery 44, a circuit may use a thin flexible battery or a cylindrical cell battery. Additionally, a circuit may use a rechargeable battery or a non-rechargeable battery. Instead of using pancake style vibrating motor 43, a circuit may use a cylindrical vibrating motor. Instead of using a single tactile switch 41, a circuit may use multiple tactile switches. Instead of using one or more tactile switches, a circuit may use one or more piezoelectric sensors. Instead of using an NPN BJT transistor 46, a circuit may use a MOSFET transistor. Instead of using a circuit board to connect the components, a circuit may use wires to connect the components. Instead of using a circuit board to keep the components colocated, a circuit may use shrink tubing to keep the components colocated.
Furthermore, a circuit may be designed to produce different patterns of tactile feedback. For example, instead of producing a short duration of continuous vibrating feedback, a circuit may produce a short duration of intermittent vibrating feedback.
Additionally, while device 1 provides tactile feedback when an athlete kicks a ball using an optimal surface of a shoe for a selected kicking technique, device 1 may be adapted to provide tactile feedback when an athlete kicks a ball using a suboptimal surface of the shoe for the selected kicking technique. In this case, the athlete may interpret a tactile sensation as negative feedback. The tactile sensation may indicate that he or she should modify his or her method of performing the selected kicking technique in order to use the optimal surface of the shoe.
While device 1 has been illustrated in terms of improving performance in the sport of soccer, device 1 may be capable of improving performance in other kicking sports including, but not limited to, American football and rugby.
Structure of the Second EmbodimentShoe 50 is adapted to practice a straight kick in soccer. When an athlete wearing shoe 50 strikes a ball using top surface 51a of shoe 50, the ball presses against tongue 52, which depresses tactile switch 41. Like in the operation of device 1, depressing tactile switch 41 triggers a short duration of tactile feedback for the athlete.
Shoe 50 may be adapted to practice additional kicking techniques by embedding circuit 40 or an equivalent circuit in additional surfaces of the shoe. For example, circuit 40 may be embedded in outstep surface 51b so that an athlete may practice outstep pass kicks. Similarly, circuit 40 may be embedded in instep surface 51c so that an athlete may practice instep pass kicks. If shoe 50 is adapted to not include a tongue 52, circuit 40 may be embedded directly in top surface 51a. Circuit 40 or an equivalent circuit may be embedded in other surfaces of shoe 50 for practicing other kicking techniques.
Structure of the Third EmbodimentTo use device 60, an athlete first selects a kicking technique to practice. Then, the athlete slides strap assembly 61 over shoe 20, positioning pouch 62 on an optimal surface of shoe 20 for the selected kicking technique. In
Like device 1, device 60 may be positioned on different surfaces of shoe 20 in order to practice different kicking techniques. For example, in
Unlike an athlete using device 60, an athlete using device 70 does not select a single kicking technique to practice before using the device. Instead, the athlete properly positions device 70 and may practice straight kicks, outstep pass kicks, and instep pass kicks without repositioning device 70.
To properly position device 70, the athlete slides strap assembly 71 over shoe 20, positioning pouch 72a on top surface 21a of shoe 20. This positioning ensures that pouch 72b is positioned on outstep surface 21b of shoe 20, and pouch 72c is positioned on instep surface 21c of shoe 20.
When the athlete kicks a ball with top surface 21a of shoe 20, the ball presses against pouch 72a, causing the instance of circuit 40 inside pouch 72a to produce a short duration of tactile feedback. Similarly, when the athlete kicks the ball with outstep surface 21b, the instance of circuit 40 inside pouch 72b produces a short duration of tactile feedback. Similarly, when the athlete kicks the ball with instep surface 21c, the instance of circuit 40 inside pouch 72c produces a short duration of tactile feedback.
In one variation of device 70, each pouch may hold a different circuit. Pouch 72a may hold a first circuit; pouch 72b may hold a second circuit, and pouch 72c may hold a third circuit. Each circuit may be configured to produce a unique pattern of tactile feedback in response to a ball impact. The unique pattern of tactile feedback identifies a specific surface of shoe 20 that made contact with a ball. For example, the first circuit inside pouch 72a may produce one short pulse of vibration in response to a ball impact; the second circuit inside pouch 72b may produce two short pulses of vibration, and the third circuit inside pouch 72c may produce three short pulses of vibration.
Structure of the Fifth EmbodimentAs shown in
Circuit 84 is also different than circuit 40. In circuit 40, positive terminal 44a of battery 44 connects to one tactile switch. In circuit 84, positive terminal 44a of battery 44 connects to three tactile switches, wired in parallel. Specifically, positive terminal 44a connects to a terminal 85a of tactile switch 85. Positive terminal 44a also connects to a terminal 86a of tactile switch 86 via wire 83a. Positive terminal 44a further connects to a terminal 87a of tactile switch 87 via wire 83c. A terminal 85b of tactile switch 85 connects to terminal 47a of resistor 47 and terminal 45a of capacitor 45. A terminal 86b of tactile switch 86 connects to terminal 47a of resistor 47 and terminal 45a of capacitor 45 via wire 83b. A terminal 87b of tactile switch 87 connects to terminal 47a of resistor 47 and terminal 45a of capacitor 45 via wire 83d.
Operation of the Fifth EmbodimentSimilarly to device 70, device 80 may be used to practice straight kicks, outstep pass kicks, and instep pass kicks without repositioning the device.
When the athlete kicks a ball with top surface 21a, outstep surface 21b, or instep surface 21c of shoe 20, the ball presses against pouch 82a, 82b, or 82c, respectively. The ball pressing against pouch 82a, 82b, or 82c depresses tactile switch 85, 86, or 87, respectively.
The electrical operation of circuit 84 is similar to the electrical operation of circuit 40. In circuit 40, when tactile switch 41 is depressed, electric current flows through the depressed switch, which causes vibrating motor 43 to vibrate for a short duration of time. Similarly, in circuit 84, when tactile switch 85, 86, or 87 is depressed, electric current flows through the depressed switch, which causes vibrating motor 43 to vibrate for a short duration of time.
Structure of the Sixth EmbodimentDevice 90 comprises thin straps. An athlete may position thin straps between cleats, as shown in
In
To use device 100, an athlete first selects a kicking technique to practice. For example, the athlete may select straight kicks, dribbling, or juggling to practice during a soccer training session. In
To practice dribbling or juggling, the athlete may clip device 100 to a forward section 22b of shoelaces 22. When the athlete kicks the ball using forward top surface 21d of shoe 20, device 100 produces a short duration of tactile feedback.
Structure of the Eighth EmbodimentCircuit 111 may comprise different components than the components illustrated in
Like device 100, depicted in
Circuit 111 uses a different set of components than circuit 40 but performs a similar function as circuit 40. Like circuit 40, circuit 111 produces a short duration of tactile feedback when tactile switch 41 is momentarily depressed.
The high voltage microcontroller 112 produces on output terminal 112c also appears at gate terminal 115b of transistor 115, which causes transistor 115 to turn on. When transistor 115 turns on, current flows from positive terminal 44a of battery 44, through motor 113, through drain terminal 115a and source terminal 115c of transistor 115, and to ground terminal 44b of battery 44. When current flows through motor 113, it vibrates.
Microcontroller 112 is programmed to keep output terminal 112c at high voltage for a short duration of time after it turns on. After the short duration of time elapses, microcontroller 112 produces a low voltage on terminal 112c. A low voltage on terminal 112c turns off transistors 114 and 115. When transistor 114 turns off, microcontroller 112 ceases to receive current at positive terminal 112a, so microcontroller 112 turns off. When transistor 115 turns off, electric current stops passing through motor 113, and motor 113 stops vibrating.
In short, when a ball impact momentarily depresses tactile switch 41, microcontroller 112 turns on. Then, microcontroller 112 outputs a high voltage on terminal 112c for a short duration of time. The high voltage on terminal 112c keeps microcontroller 112 in an on state and activates motor 113. After a short duration of time, terminal 112c drops to a low voltage, turning off microcontroller 112 and deactivating motor 113.
Because circuit 111 performs a similar function as circuit 40, circuit 111 may replace circuit 40 in any of the aforementioned embodiments in which circuit 40 is used. Specifically, circuit 111 may replace circuit 40 in devices 1, 50, 60, 70, 90, and 100.
Many different circuits with different components than circuit 111 may be implemented to produce similar results as circuit 111. For example, instead of using a single microcontroller integrated circuit, a circuit may use multiple integrated circuits such as a 555 timer and a counter to drive a vibrating motor for a short duration after a tactile switch is momentarily depressed.
In another variation of circuit 111, circuit 111 may be designed to use a piezoelectric sensor instead of tactile switch 41. A piezoelectric sensor may produce a signal representative of the magnitude of the force an athlete used to kick a ball. Microcontroller 112 may analyze the signal to determine the magnitude of the force. Microcontroller 112 may then turn on vibrating motor 113 for a duration of time proportional to the magnitude of the force. For example, when an athlete is dribbling, the athlete may strike the ball lightly, and microcontroller 112 may turn on vibrating motor 113 for a short duration of time. When the athlete is striking the ball toward a goal, the athlete may strike the ball with significant force, and microcontroller 112 may turn on vibrating motor 113 for a longer duration of time.
In yet another variation of circuit 111, circuit 111 may receive input from a plurality of sensors positioned on many different surfaces of a shoe. Each sensor may produce a signal routed to microcontroller 112. Microcontroller 112 may then analyze the sensor signals and cause vibrating motor 113 to produce tactile feedback based on an analysis of the signals. For example, microcontroller 112 may determine the first sensor that made contact with a ball, out of a plurality of sensors positioned on a top surface of a shoe. If the first sensor that made contact with the ball is positioned centrally on the top surface of the shoe, microcontroller 112 may cause vibrating motor 113 to produce a longer duration of vibrating feedback, indicating optimal contact with the ball. If the first sensor that made contact with the ball is positioned off-center from the top surface of the shoe, microcontroller 112 may cause vibrating motor 113 to produce a shorter duration of vibrating feedback, indicating suboptimal contact with the ball.
CONCLUSIONThus, it should be clear that at least one embodiment of the present disclosure promotes a more engaging, focused, and productive kinesthetic learning experience for various kicking techniques. While the above description states many specific details, these details should not be interpreted as limitations on scope, but rather as examples of possible embodiments. Many other variations are possible. Accordingly, the scope should not be determined by the embodiments illustrated, but by the appended claims and their legal equivalents.
