The popularity of extreme sports (also referred to as “action sports” or “adventure sports”) is steadily growing. In particular, sports such as snowboarding, skateboarding, free skiing, surfboarding, skydiving, wingsuit flying, bicycle motocross (BMX), and others are becoming (or are currently) mainstream sports. Such sports are increasingly being covered by various media organizations and some competitions (such as the X-Games) are devoted solely to extreme sports.
In many traditional sports, competitions are measured and judged using objective measures such as scores (e.g., the number of runs in a baseball game or points in a basketball game) or times (e.g., the time for a runner or downhill skier to cross a finish line). In many extreme sports, by contrast, athletes compete by performing various athletic maneuvers (or “tricks”) such as jumps, flips, rotations, and the like. As an example, a description of common tricks that are performed in snowboarding can be found at http://en.wikipedia.org/wiki/List_of_snowboard_tricks and a description of common skateboarding tricks at http://skateboardingtrickslist.com.
Many athletic maneuvers in extreme sports are complex and/or performed very quickly. Accordingly, athletic maneuvers performed in action sports competitions are often evaluated (by judges and spectators) based on a variety of subjective factors, including an individual's personal perception of the difficulty or aesthetics of a particular athletic maneuver. This often leads to problems in identifying different athletic maneuvers, as well as judging or rating such maneuvers in competition. In ski jump competitions, for example, the movement of the jumper may be so fast that spectators cannot determine the number of rotations or flips the jumper performs.
Some conventional systems attempt to measure fast rotations with inertial sensors. Such measurements are typically made relative to the sensor axis but can be related to the absolute axis as well. However, such conventional systems do not make sensor measurements understandable to the sport participants and spectators. Conventional systems are unable to automatically recognize and measure action sport “tricks,” and are thus unsuitable for virtual competitions, leaderboards, and social networks dedicated to the action sport participants. Embodiments of the present disclosure address these and other issues.
Embodiments of the present disclosure help identify athletic maneuvers performed by actors and/or their sports equipment using data from sensors. Among other things, various embodiments help judges and spectators of extreme sports to assess athletic maneuvers based on objective, empirical data.
A computer-implemented method according to one embodiment of the present disclosure comprises receiving, by a computer system, sensor data related to motion by an actor over a time period; determining, by the computer system and based on the sensor data, a plurality of motion characteristics; and identifying, based on the plurality of motion characteristics, an athletic maneuver associated with the motion by the actor during the time period.
Another embodiment of the present disclosure includes means for receiving sensor data related to motion by an actor over a time period; determining, based on the sensor data, a plurality of motion characteristics; and identifying, based on the plurality of motion characteristics, an athletic maneuver associated with the motion by the actor during the time period.
The present disclosure includes methods and apparatuses which perform these methods, including data processing systems which perform these methods, and computer readable media containing instructions which when executed on data processing systems cause the systems to perform these methods.
Other features will be apparent from the accompanying drawings and from the detailed description which follows.
A more complete understanding of certain embodiments may be derived by referring to the detailed description and claims when considered in connection with the following illustrative figures.
The following description and drawings are illustrative and are not to be construed as limiting. Numerous specific details are described to provide a thorough understanding. However, in certain instances, well known or conventional details are not described in order to avoid obscuring the description. References to one or an embodiment in the present disclosure are not necessarily references to the same embodiment; and, such references mean at least one.
Reference in this specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the disclosure. The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Moreover, various features are described which may be exhibited by some embodiments and not by others. Similarly, various requirements are described which may be requirements for some embodiments but not other embodiments.
Any combination and/or subset of the elements of the methods depicted herein may be practiced in any suitable order and in conjunction with any suitable system, device, and/or process. The methods described and depicted herein can be implemented in any suitable manner, such as through software operating on one or more computer systems. The software may comprise computer-readable instructions stored in a tangible computer-readable medium (such as the memory of a computer system) and can be executed by one or more processors to perform the methods of various embodiments.
Embodiments of the present disclosure may receive sensor data (105) directly or indirectly from any number and type of sensors, such as an accelerometer, a gyroscope, a magnetometer, a Hall effect sensor, a global positioning system, an ultrasonic sensor, an optical sensor; and combinations thereof. Information from different sensors may be used together or separately to determine various motion characteristics for the actor and/or the actor's equipment. As used in this context, an “actor” performing an athletic maneuver may refer to any human (e.g., skier, snowboarder, cyclist, diver, athlete, etc.) as well as to sporting equipment associated with, or controlled by, a human. Such sporting equipment may include, for example, a vehicle (such as a bicycle, boat, automobile, motorcycle, etc.), a skateboard, skis, a snowboard, a parachute, and other equipment or devices.
For example, Hall effect sensors may be used to monitor the speed of a stunt bicyclist's wheels before, during, and after a jump, while data from one set of accelerometers and gyroscopes can monitor flips and rotations performed by the bicyclist and a second set of accelerometers and gyroscopes can monitor flips and rotations of the bicycle itself Other sensors, such as an optical sensor (e.g., a proximity sensor) or global positioning system can be used to help determine actor's position with regards to the ground, ramp, other actors, and other objects. Various embodiments may utilize data from sensors imbedded in or attached to an actor's clothing, skin, equipment, or surroundings (e.g., in a ramp used by an actor to perform jumps). The sensor data may be received in any suitable manner, such as wirelessly from a data collection system coupled to an actor and/or an actor's equipment. The time interval when a maneuver or “trick” is performed can be determined by identifying and measuring a jump by monitoring and analyzing characteristic signature of the gyro sensors using fuzzy logic as described in U.S. patent application Ser. No. 13/612,470, the contents of which are incorporated by reference herein. For example,
Embodiments of the present disclosure can be particularly effective in identifying and characterizing athletic maneuvers for extreme sports based on objective data. Additionally, various embodiments may be used in conjunction with various other sports and activities, such as baseball, basketball, hockey, soccer, and football. For example, embodiments of the present disclosure may be configured to receive data from sensors coupled to a baseball player's bat, as well as from sensors attached to the player's uniform and/or embedded in a baseball. In one such embodiment, information regarding a player hitting a baseball, such as the angle of the player's swing, the velocity of the bat, and the force at which the baseball is hit can be provided to various users, such as spectators of a baseball game or trainers seeking to optimize the player's swing. As discussed in more detail below, such information can be provided in conjunction with video of the player hitting the ball, either in near-real-time as the video is broadcast to spectators, as well as part of a replay of the hit. In this manner, embodiments of the present disclosure can provide information to enhance a spectator's experience (e.g., displaying the force applied to a baseball from a 420-foot home run) as well as to help players, trainers, and coaches improve an athlete's performance based on objective information.
Any number of different motion characteristics may be determined (110). The motion characteristics may include any desired information regarding the motion of an actor or equipment used by an actor, such as position, velocity, acceleration, orientation, rotation, translation, and changes to and combinations thereof. Embodiments of the present disclosure can determine multiple motion characteristics during a period of time that includes an athletic maneuver performed by an actor. For example, the orientation of a snowboarder executing a complex series of flips and rotations during jump can be monitored at various points or times (e.g., each millisecond) within a time period starting prior to the jump and ending after the jump.
Motion characteristics may include any number of different values, descriptions, and other information characterizing the movement (or lack thereof) of an actor and/or the actor's equipment. For example, a motion characteristic associated with an athletic maneuver may include one or more of: an orientation of the actor at a time within the time period (e.g., prior to, during, or after a maneuver), an angle of rotation around a local axis of the actor, a direction of rotation of the actor around a local axis of the actor, an angle of rotation around an absolute axis perpendicular to a plane of motion of the actor, a direction of rotation round an absolute axis perpendicular to a plane of motion of the actor, and combinations thereof.
Motion characteristics may be determined in any suitable manner. For example, motion characteristics can be determined based on two different frames of reference: an absolute frame of reference that is independent of the actor and independent of the actor's motion, and a local frame of reference that is associated with (i.e., connected to, and moves with) the actor. Embodiments of the present disclosure can characterize and measure a variety of different athletic maneuvers based on analyzing a combination of motion characteristics measured relative to the absolute and local frames of reference.
Embodiments of the present disclosure may also utilize information regarding the placement or location of various sensors in determining various motion characteristics. For example, determining rotation about an axis along the actor's body may be based on sensors (e.g., accelerometers and gyroscopes) being positioned collinearly with each other, such that sensors along one of the three-dimensional axes (x, y, and z) are the same. Embodiments of the present disclosure may also utilize calibration information from the sensors, such as calibration of various sensors performed during manufacturing of the sensors or installation of the sensors in an actor's clothing, equipment, etc. Various embodiments of the present disclosure may also be configured to communicate with various sensors (or control systems coupled thereto) to calibrate the sensors. Such calibration may be performed in any suitable manner. In one embodiment, for example, calibration of one or more inertial sensors attached to an actor and/or the actor's equipment can be calibrated when the sensors indicate the actor and/or equipment is not moving.
While multiple sensors may provide a large amount of information about an actor's motion, and the motion itself can be expressed by Euler angles, pitch, roll, and yaw, or rotational matrix, this information is understood by the participants, judges, and spectators only if it is expressed in the terms and sport-specific nomenclature that is commonly accepted in the sport performed by the actor. Embodiments of the present disclosure translate sensor observations to identify “tricks” using such nomenclature. Embodiments of the present disclosure can identify key motions for each trick, detect and measure all such motions, and then identify a trick and its quality or level of difficulty by comparing the detected motions with the nominal motions required for each trick.
While not exhaustive, the most common characteristics that define different tricks are: the orientation of the actor prior to the trick (forward facing, backward facing, left side facing, right side facing), the leading edge of the trick (e.g., starting from the front or end of the user's board), rotation around an absolute axis that is horizontal and perpendicular to the direction of motion during the trick (flip axis), and rotation around an axis associated with the body of the actor (self rotation axis). In characterizing a trick, a rotation angle around any axis does not have to be a full rotation but could be a “back and forth” swing at some particular angle, (e.g., a “Shifty” trick).
In various embodiments, determining the orientation of an actor (or the actor's equipment) at various points during a time period includes determining an angle of self-rotation for the actor and determining an angle of flip for the actor. For example, an actor (such as a skateboarder) performing a jump may be monitored using three gyroscopes and three accelerometers connected to the actor's equipment, body, or clothing. For this example, it is assumed that all the sensors are positioned in a device such that their local axes are collinear as described above. The orientation of the actor at time t with respect to a fixed reference frame is determined by a quaternion L(t). The quaternion change satisfies the following kinematic equation:
L_dot=½° L, (Equation 1)
In Equation 1, L_dot is a time derivative of L(t), ω is angular velocity of the body, measured by (for example) the gyroscopic sensors. As an initial condition, L(0) (i.e., the orientation of the actor before the jump) can be determined. Alternatively, the orientation of the actor immediately after the jump can be determined, namely L(t_max) where t_max is a time after the actor lands. The orientation of the actor (including the actor's facing/orientation prior to, or after, a maneuver) can be determined in any desired manner, such as based on a direction of a velocity vector calculated from the sensor data (e.g., from a GPS sensor) and the orientation of the actor calculated from other sensor data (e.g., from a magnetometer).
In a practical system, determining L(t_max) may be preferable where a landing shock (i.e., a large acceleration after the jump) in the opposite directed with respect to gravity is measurable. Given the orientation of the actor after the jump, the equation thus becomes:
L(t_max)≈[cos φ/2; e sin φ/2];
e=(g×a_shock)/(|g·a_shock|); and
φ=a cos((g·a_shock)/⊕g∥a_shock|).
Here, “≈” means that there may be some error associated with the final quaternion L(t_max), however this approximation may still be sufficient from practical point of view where the absolute orientation of the sportsman is not needed for calculation of turns during the jump.
Given the orientation at the end of the jump, L(t_max), the equations may be reformulated in classical Cauchy form (ODE with initial conditions), and using the new variable τ:
t=tmax−τ.
Substituting the given expression into Equation 1 obtains:
d/dt L=−d/dτ L=½ ω(tmax−τ)° L(tmax−τ).
Thus orientation of the sportsman can be determined solving the following
Cauchy problem:
(d/dτ L{tilde over ( )}(τ)=−½ω{tilde over ( )}(τ)° L{tilde over ( )}(τ)
τ∈[0; tmax];
In this example, a local vertical axis may be determined to (for example) calculate an angle of self-rotation of the actor during the jump. A local vertical axis may be determined in a variety of different ways, including based on an average of sensor data from one or more accelerometers prior to the athletic maneuver, an average of sensor data from one or more accelerometers after the athletic maneuver, sensor data from one or more accelerometers associated with a portion of the athletic maneuver (such as a landing performed after the maneuver), sensor data from one or more magnetometers (e.g., in conjunction with the nominal orientation of a magnetic vector relative to the vertical at the location of the event), and combinations thereof.
The angle of self-rotation for the actor may be determined in any suitable manner, including by calculating a path for each of a plurality of unit vectors in a local frame of reference that is associated with the actor, the plurality of unit vectors being orthogonal to a local vertical vector for the actor. The angle of self-rotation for the actor may then be selected as the largest rotation angle among such unit vectors.
Likewise, the angle of flip for the actor may be calculated in any desired manner, including by determining the motion of a vertical vector in a global frame of reference that is associated with the actor, identifying a plane of movement for the unit vertical vector, calculating a projection of the vertical vector on the plane, and selecting the angle of flip for the actor as the angle of the arc traveled by such projection on the plane.
Definitions for any desired athletic maneuvers can be received (115), associated with one or more motion characteristics (120), and stored in a database for future reference and retrieval (125). A definition for an athletic maneuver may apply to any movement or group of movements by an actor, the actor's equipment, or a combination thereof. For example, a back flip combined with a side flip performed by a snowboarder is often referred to as a “wildcat.” A definition for a wildcat maneuver may thus include the name (or aliases) of the maneuver, a textual description of the maneuver, and the motion characteristic(s) associated with the maneuver. Continuing this example, the motion characteristics associated with the wildcat may include indicators of the different axes of rotation by the actor's body and the rotation angles around these axes. Other information, such as a typical range of forces exerted on the actor's snowboard or parts of the actor's body and a range of time the snowboarder is airborne may be associated with the definition to help identify future wildcat jumps by comparing measured motion characteristics to the wildcat jump definition in the database.
The definition for an athletic maneuver may include any number of complex movements by an actor and/or the actor's equipment. For example, sensor data from sensors attached to the actor (such as a skateboarder) can be analyzed in conjunction with sensor data from the actor's equipment (such as a skateboarder). In this manner, rotations, flips, and other movement by the actor can be analyzed together with rotations and flips of the skateboard to identify all movements performed by the actor and provide a complete and accurate characterization of the maneuver performed. Embodiments of the present disclosure can thus be particularly effective in characterizing and identifying maneuvers that are complex and/or fast, therefore making it challenging for spectators and judges to identify all the movements involved.
A definition for an athletic maneuver may include, or be associated with, any other desired information. For example, statistics (including motion characteristics) for particular athletes who perform a maneuver may be linked to the definition of the maneuver in a database, allowing users of the systems and methods of the present disclosure to compare the manner in which various athletes perform the maneuver. Other information, such as video of the maneuver being performed, may likewise be included in, or linked to, the definition.
One or more determined motion characteristics can be compared to the motion characteristics associated with a known athletic maneuvers in a database to identify the maneuver (130) associated with the determined motion characteristics. The motion characteristics determined for an unknown maneuver may be compared to motion characteristics for known maneuvers in any suitable manner. For example, characteristics describing an actor's velocity, angle of self-rotation, angle of flip, and change in orientation during a time period can be compared to a relational database storing motion characteristics associated with the known maneuvers. Known motion characteristics in the database may be represented in nominal values and/or in ranges, reflecting that different actors may have different physical characteristics (e.g., height, weight), may have different equipment, may perform the same maneuver somewhat differently, and/or may perform a maneuver under various other conditions (e.g., with different types of ramps).
The database may also specify the quality of the maneuver that is associated with different parameter values. For example, a full rotation of 360 degrees during a jump may be valued in 10 points, while a partial rotation of only 350 dg (from jump start to landing) may be valued only at 9 points. The quality of a maneuver may be determined according to any desired factors, such as the difficulty of the maneuver.
A level of similarity between a determined set of motion characteristics and a known nominal set of motion characteristics may be determined (135). The level of similarity may be determined for each of a plurality of motion characteristics. Alternatively (or in addition), an overall level of similarity may be determined for an entire maneuver. The level(s) of similarity may be compared to various threshold values, and an alert generated if one or more similarity levels fail to meet a threshold value. In this manner, embodiments of the present disclosure can identify new (i.e., undefined) maneuvers and help administrators and users of the systems and methods described herein to identify errors in the values or associations of stored motion characteristics and modify them appropriately.
Embodiments of the present disclosure may combine or overlay information identified and/or measured for an athletic maneuver (145) with any desired form of media. For example, information regarding an athletic maneuver can be combined or overlaid onto video taken of the athletic maneuver, thus providing near-real-time information on a maneuver to spectators or judges. Such an overlay can be synchronized in any desired manner, including by using a time measured from a global positioning system or other sensor operating in conjunction with embodiments of the present disclosure.
Embodiments of the disclosure may also be configured to automatically generate and transmit reports, statistics, and/or analyses based on information related to various athletic maneuvers. These may be provided in real-time or near-real-time to judges, spectators, social media outlets, broadcasting entities, websites, and other systems and entities.

Accordingly, any portion of the system or a module may take the form of a processing apparatus executing code, an internet based embodiment, an entirely hardware embodiment, or an embodiment combining aspects of the internet, software and hardware. Furthermore, the system may take the form of a computer program product on a computer-readable storage medium having computer-readable program code means embodied in the storage medium. Any suitable computer-readable storage medium may be utilized, including hard disks, CD-ROM, optical storage devices, magnetic storage devices, and/or the like.
The system and method is described herein with reference to screen shots, block diagrams and flowchart illustrations of methods, apparatus (e.g., systems), and computer program products according to various embodiments. It will be understood that each functional block of the block diagrams and the flowchart illustrations, and combinations of functional blocks in the block diagrams and flowchart illustrations, respectively, can be implemented by computer program instructions.
These computer program instructions may be loaded onto a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions that execute on the computer or other programmable data processing apparatus create means for implementing the functions specified in the flowchart block or blocks. These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function specified in the flowchart block or blocks. The computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer-implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart block or blocks.
Accordingly, functional blocks of the block diagrams and flowchart illustrations support combinations of means for performing the specified functions, combinations of steps for performing the specified functions, and program instruction means for performing the specified functions. It will also be understood that each functional block of the block diagrams and flowchart illustrations, and combinations of functional blocks in the block diagrams and flowchart illustrations, can be implemented by either special purpose hardware-based computer systems which perform the specified functions or steps, or suitable combinations of special purpose hardware and computer instructions. Further, illustrations of the process flows and the descriptions thereof may make reference to user windows, webpages, websites, web forms, prompts, etc. Practitioners will appreciate that the illustrated steps described herein may comprise in any number of configurations including the use of windows, webpages, web forms, popup windows, prompts and the like. It should be further appreciated that the multiple steps as illustrated and described may be combined into single webpages and/or windows but have been expanded for the sake of simplicity. In other cases, steps illustrated and described as single process steps may be separated into multiple webpages and/or windows but have been combined for simplicity.
The term “non-transitory” is to be understood to remove only propagating transitory signals per se from the claim scope and does not relinquish rights to all standard computer-readable media that are not only propagating transitory signals per se. Stated another way, the meaning of the term “non-transitory computer-readable medium” should be construed to exclude only those types of transitory computer-readable media which were found in In Re Nuijten to fall outside the scope of patentable subject matter under 35 U.S.C. §101.
Benefits, other advantages, and solutions to problems have been described herein with regard to specific embodiments. However, the benefits, advantages, solutions to problems, and any elements that may cause any benefit, advantage, or solution to occur or become more pronounced are not to be construed as critical, required, or essential features or elements of the disclosure.
Although the disclosure includes a method, it is contemplated that it may be embodied as computer program instructions on a tangible computer-readable carrier, such as a magnetic or optical memory or a magnetic or optical disk. All structural, chemical, and functional equivalents to the elements of the above-described exemplary embodiments that are known to those of ordinary skill in the art are expressly incorporated herein by reference and are intended to be encompassed by the present claims. Moreover, it is not necessary for a device or method to address each and every problem sought to be solved by the present disclosure, for it to be encompassed by the present claims. Furthermore, no element, component, or method step in the present disclosure is intended to be dedicated to the public regardless of whether the element, component, or method step is explicitly recited in the claims. No claim element herein is to be construed under the provisions of 35 U.S.C. 112, sixth paragraph, unless the element is expressly recited using the phrase “means for.” As used herein, the terms “comprises”, “comprising”, or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
Changes and modifications may be made to the disclosed embodiments without departing from the scope of the present invention. These and other changes or modifications are intended to be included within the scope of the present disclosure, as expressed in the following claims.
