Stationary exercise machines have become an increasingly popular way to exercise. To combat the boredom and burnout that is often experienced by users that exercise with these exercise machines, exercise machines are often sold with a number of different pre-programmed workout programs that are saved within the electronics of the exercise machines. For example, these workout programs may include a “fat burn” workout program, a “hills” workout program, a “performance” workout program, and/or other workout programs.
To enable a user to become more immersed in a workout performed on an exercise machine, some exercise machines are capable of executing video workout programs. A video workout program generally includes a video that depicts a trainer performing a workout to allow one or more users to mimic the workout. For example, where a trainer is running at 6 miles per hour in a video of a video workout program, multiple users may control the running belts of their respective treadmills to likewise operate at 6 miles per hour. Where multiple users are following a trainer depicted in a video workout program, the video workout program may include a leaderboard that ranks the performances of the multiple users during the video workout program. Effective leaderboards can connect users with each other and can make a workout more fun.
One problem faced by users when following a video workout program that includes a leaderboard is that the leaderboard rankings are sometime inaccurate because they do not reflect actual performances by all users. For example, some users may cause their performance during a workout to be reported inaccurately, either intentionally or unintentionally, resulting in a higher leaderboard ranking for those users. Inaccurate leaderboard rankings can be frustrating to users whose performances are accurately reported, especially when the users with inaccurately-reported performances appear higher in the leaderboard rankings. This lack of accuracy in leaderboard rankings in a video workout program can seem unfair and be upsetting to a user of an exercise machine, and can thus limit the ability of the leaderboard to connect the user with other users and make the workout more fun.

It is to be understood that both the foregoing summary and the following detailed description are explanatory and are not restrictive of the invention as claimed.
Embodiments will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
Throughout the drawings, identical reference numbers designate similar, but not necessarily identical, elements.
While conventional stationary exercise machines generally include multiple conventional workout programs that are saved within the electronics of the exercise machines, these conventional workout programs are generally not effective at enabling a user to become immersed in workouts performed on the exercise machines. Therefore, some exercise machines are capable of being updated with video workout programs that include a video of a trainer performing a workout to allow one or more users to mimic the workout of the trainer. Video workout programs may also include corresponding control commands that control the exercise machine to mimic the workout performed by the trainer in the video. For example, where a trainer is depicted as running at 6 miles per hour in the video (either along a real-world path such as in a race setting, or on a treadmill in a class setting) of a video workout program, multiple users may control the running belts of their respective treadmills to likewise operate at 6 miles per hour, or the corresponding control commands may control the running belts of their respective treadmills to likewise operate at 6 miles per hour. Where multiple users are following a trainer depicted in a video workout program, the video workout program may include a leaderboard that ranks the performances of the multiple users during the video workout program. Effective leaderboards can connect users with each other and can make a workout more fun.
Unfortunately, however, leaderboards are sometimes less effective because their rankings are sometimes inaccurate because they do not reflect actual performances by all users. For example, some users may cause their performance during a workout to be reported inaccurately, either intentionally or unintentionally, resulting in a higher leaderboard ranking for those users. For example, where a trainer is depicted as running at 6 miles per hour at a 4.5% incline in the video of a video workout program, most users may control the running belts of their respective treadmills to likewise operate at 6 miles per hour at a 4.5% incline, or the corresponding control commands may control the running belts of their respective treadmills to likewise operate at 6 miles per hour at a 4.5% incline, and further accurately report that they are following the workout of the trainer. However, some users may manually cause the running belts of their respective treadmills to operate at 6 miles per hour but at only a 1% incline, but inaccurately report, either intentionally or unintentionally, that they are following the workout of the trainer (including the 4.5% incline). Because running at a 1% incline is dramatically easier than running at a 4.5% incline, these inaccurately-reporting users may run farther than the accurately-reporting users, resulting in a higher leaderboard ranking for these inaccurately-reporting users. Inaccurate leaderboard rankings can be frustrating to users whose performances are accurately reported, especially when the users with inaccurately-reported performances appear higher in the leaderboard rankings. This lack of accuracy in leaderboard rankings in a video workout program can seem unfair and be upsetting to an accurately-reporting user of an exercise machine, and can thus limit the ability of the leaderboard to connect the user with other users and to make the workout more fun.
Some embodiments disclosed herein may include methods for updating a leaderboard in an exercise machine system with an irregularity flag. For example, a method may include executing a video workout program (which may be live or archived) on first and second exercise machines (which may be located locally, such as in the same room in a class setting, or may be located remotely from one another, such as in different homes) to enable first and second users to perform a workout (either simultaneously or at different times), and monitoring performance parameters of the first and second users during the execution of the video workout program on the first and second exercise machines. The method may further include displaying, on first and second displays at the first and second exercise machines, a leaderboard which displays and ranks a first performance indicator of the first user and a second performance indicator of the second user based on the first and second performance parameters. For example, the leaderboard may continuously rank the first and second users based on some performance parameter, such as which user has traveled the greatest distance or gained the most elevation at any given point in time during the workout. The method may also include detecting an irregularity in the performance parameters of the first user (e.g., detecting that the first user manually decreased the incline percentage on their treadmill, resulting in the first user no longer fairly competing against the second user who maintained their incline percentage at the prescribed percentage). When such an irregularity is detected, the method may include updating the leaderboard, on the first and second displays at the first and second exercise machines, to display an irregularity flag (e.g., a yellow circle) associated with the first performance indicator of the first user to indicate the irregularity in the performance of the first user during the workout.
Displaying any user with detected irregularities in their performance parameters on the leaderboard with an irregularity flag may lessen or eliminate the frustration and sense of unfairness felt by users who follow the workout prescribed in a video workout program. As such, effectively employing irregularity flags on a leaderboard may allow users to have greater trust in the leaderboard rankings, and may allow a leaderboard to more effectively connect users with each other and make the workout more fun.
Turning now to the drawings,
In some embodiments, the network 118 may be configured to communicatively couple the any two devices in the exercise machine system 100 to one another, and/or to other devices. In some embodiments, the network 118 may be any wired or wireless network, or combination of multiple networks, configured to send and receive communications between systems and devices. In some embodiments, the network 118 may include a Personal Area Network (PAN), a Local Area Network (LAN), a Metropolitan Area Network (MAN), a Wide Area Network (WAN), a Storage Area Network (SAN), the Internet, or some combination thereof. In some embodiments, the network 118 may also be coupled to, or may include, portions of a telecommunications network, including telephone lines, for sending data in a variety of different communication protocols, such as a cellular network or a Voice over IP (VoIP) network.
In the remote location 102, the exercise machine system 100 may include a video camera 106a or 106b that may be employed to capture video of a trainer 108a or 108b performing a workout, and which includes stabilization capabilities to avoid the captured video from being unduly shaky. For example, the video camera 106a may be employed by a videographer 110a to capture video of the trainer 108a performing a workout in which the trainer 108a runs a live marathon. Similarly, the video camera 106b may be employed by a videographer 110b to capture video of the trainer 108b performing a workout in which the trainer 108b rides a bicycle in a live road bicycle race. In either example, the result may be captured video that can be sent to a remote server 112 for further processing. The video may be formatted in any one of multiple video formats, at least some of which being capable of supporting a subtitle stream. Some example formats may include, but are not limited to, MPEG-4, Dynamic Adaptive Streaming over HTTP (MPEG-DASH), and HTTP Live Streaming (HLS).
Next, a producer (not shown) may utilize a computer 114 to input exercise machine control commands for the video into a video workout program, which may be encoded into a subtitle stream of the video, or may be encoded separately from the video. For example, where the video is being produced to be utilized as a live video workout program, the producer may input the exercise machine control commands using the computer 114 synchronously with the videographer 110a or 110b using the video camera 106a or 106b to capture video of the trainer 108a or 108b performing the workout (e.g., during a live event). In this example, the producer may also give corresponding instructions to the trainer, such as through an earpiece worn by the trainer, in order to help the trainer and the producer be in sync following a common script or plan for the workout. Alternatively, where the video is produced to be utilized in a pre-recorded video workout program, the producer may input exercise machine control commands using the computer 114 subsequent to the videographer 110a or 110b using the video camera 106a or 106b to capture video of the trainer 108a or 108b (e.g., minutes, hours, or days after the live event).
In some embodiments, the video workout program, including the captured video and the control commands (which may be encoded in the subtitle stream of the video, or may be encoded separately from the video) may then be transmitted over the network 118 from the remote server 112 in the remote location 102 to a local server 116 in the local location 104.
The video workout program may then be transmitted from the local server 116 to be used in connection with an exercise machine 120a, 120b, 120c, or 120d. For example, the video workout program may be transmitted from the local server 116 to a console 122a, 122b, 122c, or 122d of the exercise machine 120a, 120b, 120c, or 120d, which may include a display, such as a touchscreen display. Alternatively, a separate tablet 124 may function as a console, or may function in connection with a console, of the exercise machine 120a, 120b, 120c, or 120d, and may also include a display, such as a touchscreen display. The tablet 124 may communicate with the console 122a, 122b, 122c, or 122d, and/or with the exercise machine 120a, 120b, 120c, or 120d, via a network connection, such as a Bluetooth connection. In either example, the video and the control commands (which may be encoded in the subtitle stream of the video) may be decoded and/or accessed. Then, the console 122a, 122b, 122c, or 122d and/or the tablet 124 may display the video from the video workout program (e.g., of the trainer 108a or 108b performing the marathon or the road bicycle race at the remote location 102) while simultaneously controlling one or more moveable members of the exercise machine 120a, 120b, 120c, or 120d using the control commands. Additional details regarding controlling an exercise machine using control commands can be found in U.S. patent application Ser. No. 16/742,762, filed Jan. 14, 2020, which is incorporated herein by reference in its entirety for all that it discloses.
Further, during performance of a workout by a user 109a using the video workout program on the exercise machine 120a, 120b, 120c, or 120d, a heart rate of the user 109a may be monitored by the console 122a, 122b, 122c, or 122d, and/or the tablet 124. This heart rate monitoring may be accomplished by receiving continuous heart rate measurements wirelessly (such as over Bluetooth or Ant+) from a heart rate monitoring device worn by the user 109a, such as a heart rate strap 111b or a heart rate watch 111a, or other wearable heart rate monitor. Alternatively, the heart rate monitoring device may be built into another device, such as being built into handlebars or handgrips of the exercise machine 120a, 120b, 120c, or 120d.
The heart rate strap 111b and the heart rate watch 111 are examples of sensors that may be used to generate and/or gather performance parameters or other information of users of the exercise machines 120a, 120b, 120c, and/or 120d. Such sensors may generally include heart rate sensors (such as may be included in the heart rate strap 11b and the heart rate watch 111), current sensors, speed sensors (e.g., tachometers), weight sensors, gait sensors, fingerprint sensors, biometric sensors (e.g., heart rate sensors, gait sensors, fingerprint sensors), accelerometers, or other sensors. Such sensors may be integrated with, included in, coupled to, or otherwise associated with one or more of the exercise machines 120a, 120b, 120c, and/or 120d and/or the users of the exercise machines 120a, 120b, 120c, and/or 120d.
The exercise machine 120a is illustrated in
The exercise machine 120b is illustrated in
The exercise machine 120c is illustrated in
The exercise machine 120d is illustrated in
In some embodiments, multiple users may use the same exercise machine or different exercise machines to perform the same workout using the same video workout program, either simultaneously (e.g., by performing a live video workout or by performing an archived video workout with the same actual start time) or at separate times (e.g., by performing an archived video workout with different start times, but that are time shifted to have the same virtual start times). For example, the trainer 108a may be depicted as performing a running workout in the video (either along a real-world path, or on a treadmill) of a video workout program, and the user 109a may perform the same running workout of the video workout program on the treadmill 120a. Simultaneously at two or more separate times, at the same local location 104 or at two or more separate locations, multiple other users, including the user 109b, may also perform the same running workout of the video workout program on their separate treadmills, such as on the treadmill 120d. Where multiple users are following a trainer depicted in a video workout program, the video workout program may include a leaderboard (e.g., the leaderboards 420a-420d disclosed in
Unfortunately, however, leaderboard rankings are sometime inaccurate in that they do not reflect actual performances by all users. Continuing the example above, the user 109a may cause his performance during the running workout to be reported inaccurately, either intentionally or unintentionally, resulting in a higher leaderboard ranking for the user 109a. For example, where the trainer 108a is depicted as running at 6 miles per hour at a 4.5% incline in the video of the video workout program, while most of the users, including the user 109b, may control the running belts of their respective treadmills to likewise operate at 6 miles per hour at a 4.5% incline, or the corresponding control commands may control the running belts of their respective treadmills to likewise operate at 6 miles per hour at a 4.5% incline, the user 109a may manually cause the running belt 126a of his treadmill 120a to operate at less than 6 miles per hour (e.g., at 4 miles per hour) and/or at less than a 4.5% incline (e.g., at a 1% incline), but inaccurately report, either intentionally or unintentionally, that he is following the workout of the trainer (including the 6 miles per hour and the 4.5% incline). Because running at 4 miles per hour and/or at a 1% incline is dramatically easier than running at 6 miles per hour and at a 4.5% incline, the inaccurately-reporting user 109a may run farther than the accurately-reporting users (such as the user 109b), resulting in a higher leaderboard ranking for the inaccurately-reporting user 109a. Inaccurate leaderboard rankings can be frustrating to users whose performances are accurately reported, especially when the user 109a with the inaccurately-reported performance appears higher in the leaderboard rankings. This lack of accuracy in leaderboard rankings in a video workout program can seem unfair and be upsetting to an accurately-reporting user of an exercise machine, such as the user 109b, and can limit the ability of the leaderboard to connect the user 109b with other users and to make the workout more fun.
Continuing with the example above, some methods disclosed herein may include detecting an irregularity in the performance parameters of the user 109a (e.g., detecting that the user 109a manually decreased the speed and/or decreased the incline percentage on his treadmill 120a, resulting in the user 109a no longer fairly competing against the other users, such as the user 109b, who maintained their speed and incline percentage at the prescribed speed and incline percentage). When such an irregularity is detected, some methods disclosed herein may include updating the leaderboard to display an irregularity flag (e.g., a yellow circle) associated with the first performance indicator of the user 109a to indicate the irregularity in the performance of the user 109a during the workout. Displaying the user 109a with an irregularity flag may lessen or eliminate the frustration and sense of unfairness felt by the other users, such as the user 109b, who follow the workout prescribed in a video workout program. As such, effectively employing irregularity flags on a leaderboard may allow users to have greater trust in the leaderboard rankings, and may allow the leaderboard to connect users with each other and make the workout more fun.
As disclosed in
Data, including data in a video workout program, can be received by the exercise machine 120 through the receiving port 152. As stated previously, a video workout program may include video as well as control commands. Control commands may provide control instructions to an exercise machine (such as a treadmill, an elliptical machine, an exercise bike, or a rower machine). Control commands may include, for example, control commands for a belt motor, an incline motor, and other actuators. In addition to actuator control commands, control commands may further include distance control commands, time control commands, and/or heart rate zone control commands. These control commands may provide a series of actuator control commands for execution at specific times or at specific distances. For example, a control command for an actuator to be at a certain level for a specific amount of time or for a specific distance. These control commands may also provide a series of actuator control commands for execution at specific times or at specific distances based on a user's monitored heart rate or heart rate trends over time. For example, a control command for an actuator may dictate a certain heart rate zone for a certain amount of time or distance, and a difficulty level of this control command may be dynamically scaled based on a user's monitored heart rate in order to get or keep the user in the certain heart rate zone for the certain amount of time or distance. Additional details regarding dynamically scaling a difficulty level of a control command based on a user's monitored heart rate can be found in U.S. patent application Ser. No. 16/742,762, filed Jan. 14, 2020, which is incorporated herein by reference in its entirety for all that it discloses.
Using a control command, received at the receiving port 152 in a video workout program, such as a control command that is decoded from a subtitle stream of a video of a video workout program for example, the processing unit 150 may control the actuator 154 on the exercise machine 120 in the sequence and at the times or distances specified by the control command. For example, actuator control commands that provide the processing unit 150 with commands for controlling a belt motor, an incline motor, a flywheel brake, stride length motor, or another actuator may be included in the control commands received in a video workout program at the exercise machine 120.
Actuator control commands can be received for different time segments or distance segments of a workout. For example, a ten minute workout may have twenty different control commands that provide the processing unit 150 with a different control command for controlling an actuator every thirty seconds. Alternatively, a ten mile workout may have twenty different control commands that provide a processing unit with a different control command for controlling an actuator every half mile. Workouts may be of any duration or distance and different control commands may be received at any time or distance during the workout. Alternatively, a 5 minute workout may have 300 different control commands that provide the processing unit 150 with a different control command for controlling an actuator once per second.
The control commands received in a video workout program at the exercise machine 120 may be executed by the processing unit 150 in a number of different ways. For example, the control commands may be received and then stored into a read/write memory that is included in the processing unit 150. Alternatively, the control commands may be streamed to the exercise machine 120 in real-time. The control commands may also be received and/or executed from a portable memory device, such as a USB memory stick or an SD card.
In some embodiments, data received by the exercise machine 120 through the receiving port 152 with the video workout program may also include leaderboard data associated with a leaderboard of the video workout program. This leaderboard data may include data associated with individual users who are performing or who have performed a workout of the video workout program. This leaderboard data may be employed by the processing unit 150 to display a leaderboard along with a video of the video workout program on a display associated with the exercise machine 120. Further, in some embodiments, control commands executed by the processing unit 150 may be manually overridden by a user. For example, actuator control commands received in a video workout program that provide the processing unit 150 with commands for controlling a motor of the running belt 126a of the treadmill 120a (see
The frames 300a-300d of video captured of the trainer 108a running the marathon represent frames of video captured in succession, one second apart. It is understood, however, that other intervening frames of video may also be captured, such as 29 intervening frames of video between each of the successive frames 300a-300d, resulting in a captured video having 30 frames per second. The reason that only one frame per second are illustrated in the frames 300a-300d of video is because the encoding of control commands of a video workout program into a subtitle stream of a video of the video workout program may occur only once per second in the example encoding disclosed in
As disclosed in the frame 300a of
As disclosed in the frame 300b of
As disclosed in the frame 300c of
As disclosed in the frame 300d of
Due to the fact that, in a video, the frames 300a-300d from the video are timed with frames of the subtitle stream, the encoding of control commands in a subtitle stream, such as in the CSV encodings 305a-305d illustrated in the CSV encoding charts 304a-304d, maintains synchronization of the video of a video workout program and of corresponding control commands of the video workout program. For example, even if the video is buffered or otherwise delayed, the subtitle stream will also be buffered or otherwise delayed by an identical amount, which will maintain synchronization of the video and of corresponding control commands. This synchronization between a video and corresponding control commands in a video workout program can enable a user to become immersed in a workout on the exercise machine.
The frames 400a-400d of a video, which show the trainer 108a running the marathon, represent frames of video captured over time. It is understood, however, that other intervening frames of video may also be captured between each of the frames 400a-400d, resulting in a captured video having additional frames (e.g., with a frame rate of 24, 30, or 60 frames per second).
As disclosed in the frame 400a of

Further, as disclosed in the leaderboard 420a, with 22 minutes and 30 seconds remaining in the workout, the user 109b (named Brent S. with performance indicators 422, which include a current or average speed in miles per hour and a total distance in miles) sits atop the leaderboard 420a due to the fact that Brent S. has run further during the workout than any other user. In other words, at the time of the leaderboard 420a, Brent S. is in first place in the leaderboard 420a (represented by a crown), while user 109a (named Luis M. with performance indicators 424) is in second place, and Jay C. (with performance indicators 426) is in third place.
As disclosed in the frame 400b of

However, due to one or more irregularities having been detected during the workout of Luis M. (with the performance indicators 424) sometime between the times of the frame 400b and the frame 400c (e.g., it was detected that Luis M. manually caused the running deck 126k of the treadmill 120d to operate at only a 1% incline instead of the prescribed 4.5% incline), the leaderboard 420c has been updated to display an irregularity flag 427 associated with the performance indicators 424 of Luis M., to indicate one or more irregularities in the performance of Luis M. during the workout. Thus, the irregularity flag 427 serves to alert all of the users, and anyone else viewing the leaderboard 420c, that one or more irregularities were detected sometime during the workout performed by Luis M., and therefore the ranking of Luis M. in first place may not be a legitimate ranking.
As disclosed in the frame 400d of
However, due to one or more irregularities having been detected in the performance of Luis M. (with the performance indicators 424) sometime previously in the workout, such as between the times of the frame 400b and the frame 400c, the leaderboard 420c continues to display an irregularity flag 427 associated with the performance indicators 424 of Luis M., to indicate one or more irregularities in the performance of Luis M. during the workout. Thus, the irregularity flag 427 serves to alert all of the users, and anyone else viewing the leaderboard 420d, that one or more irregularities were detected sometime during the workout performed by Luis M., and therefore the ranking of Luis M. in first place may not be a legitimate ranking.
It is understood that leaderboards similar to the leaderboards 420a-420d shown on the display of the user 109b in
Prior to the method 500, multiple users, such as the user 109a and 109b, may be subscribed to a subscription service (e.g., an IFIT account) that allows the users to have access to video workout programs, and the users may have logged in, or signed in, to this subscription service. This subscription service may store user profiles, as well as history information related to each user's sleep, nutrition, stress levels, exercise, wellness, and activity levels (which may be gathered automatically via sensors, or manually entered by the users). This profile and history information may be accessed to recommend particular video workout programs that will best help each user to achieve fitness goals set by the user or automatically generated for the user. By providing high quality video workout programs, a user may be incentivized to continue subscribing, and a retention rate for subscribers may be positively impacted. Further, some video workout programs employed using the method 500 may be accessed by user using a pay-per-view model rather than an ongoing subscription model. For example, a pay-per-view model may be appropriate for rare events or classes, or for one-on-one training sessions between a single trainer and a single user.
Further, prior to the method 500, video may be captured, exercise machine control commands may be encoded into the video to create a video workout program, and the video workout program may be transmitted to first and second exercise machines. For example, the video camera 106a may be employed by the videographer 110a to capture video of the trainer 108a performing a workout. In this example, the workout being performed by the trainer 108a may be running a marathon, and the video may be transmitted from the video camera 106a to the remote server 112 for further processing. Then, the computer 114 may be employed by a producer to encode exercise machine control commands into the video (such as in a subtitle stream of the video) to create a video workout program, which is then transmitted to multiple exercise machines (such as the treadmills 120a and 120d). In some embodiments, the exercise machine control commands may be configured to control a speed of one or more moveable members of the exercise machines and/or an incline percentage of one or more moveable members of the exercise machines. For example, the CSV encoding 305a, 305b, 305c, or 305d may include a control command configured to control the speed (e.g., in the 2nd position of the CSV encoding) of the running belts 126a and 126j of the treadmills 120a and 120d, as well as a control command configured to control the incline percentage (e.g., in the 3rd position of the CSV encoding) of the running decks 126b and 126k of the treadmills 120a and 120d. In some embodiments, changes in the exercise machine control commands may be synchronized with associated changes in a workout depicted in the video. For example, as the trainer 108a changes from running on a 0.5% incline to running on a 4.5% incline, which change is depicted in frames 300b and 300c of the video, the exercise machine control commands that are encoded with the frames 300b and 300c may be synchronized to reflect this change, namely, that the incline percentage should change from 0.5% to 4.5% (compare the 3rd position of the CSV encoding 305b to the 3rd position of the CSV encoding 305c).
The method 500 may include, at action 502, executing a video workout program to enable a first user to perform a workout on the first exercise machine. In some embodiments, the video workout program may include a video that depicts a trainer performing the workout and exercise machine control commands corresponding to the depiction of the trainer performing the workout in the video. In some embodiments, the executing video workout program may continuously control one or more first moveable members of the first exercise machine using the exercise machine control commands. In some embodiments, the video workout program is a live video workout program. In some embodiments, the video workout program is an archived video workout program. For example, the console 122a of the treadmill 120a may execute, at action 502, a video workout program. The video workout program may include a video that includes the frames 500a-500d (as well as intervening frames) that depict the trainer 108a performing a workout that includes running a marathon. This executing video workout program may enable the user 109a to perform the workout depicted by the trainer 108a on the treadmill 120a automatically (e.g., the speed and incline of the treadmill 120a may be adjusted automatically based on the exercise machine control commands associated with the video workout program).
The method 500 may include, at action 504, monitoring first performance parameters of the first user during the execution of the video workout program. For example, the console 122a of the treadmill 120a, the local server 116, or the remote server 112, or some combination thereof, may monitor, at action 504, first performance parameters of the user 109a during the execution of the video workout program on the treadmill 120a. The first performance parameters may include performance parameters automatically gathered by sensors in the treadmill 120a, sensors worn by the user 109a, or other sensors. The first performance parameters gathered by the sensors may be received at the treadmill 120a from the sensors. Alternatively or additionally, the first performance parameters gathered by the sensors at the treadmill 120a may be provided to and received at one or more other exercise machines 120, the local server 116, and/or the remote server 112.
The method 500 may include, at action 506, executing the video workout program to enable a second user to perform the workout on the second exercise machine. For example, the console 122d of the treadmill 120d may execute, at action 506, the same video workout program executed at action 502 by the console 122a of the treadmill 120a. This executing video workout program may enable the user 109b to perform the workout depicted by the trainer 108a on the treadmill 120d automatically. This executing at action 506 may be performed simultaneously with the executing at action 502 (e.g., in a live competition or class) or may be performed before or after the executing at action 502 (e.g., in an archived competition or class). The treadmill 120d may be located locally, to or remotely from, the treadmill 120a.
The method 500 may include, at action 508, monitoring second performance parameters of the second user during the execution of the video workout program. For example, the console 122d of the treadmill 120d, the local server 116, or the remote server 112, or some combination thereof, may monitor, at action 508, second performance parameters of the user 109b during the execution of the video workout program on the treadmill 120d.
The method 500 may include, at action 510, generating a leaderboard which displays and ranks first and second performance indicators of the first and second users based on the first and second performance parameters. For example, the consoles 122a and 122d, the local server 116, or the remote server 112, or some combination thereof, may generate, at action 510, the leaderboards 420a and 420b which display and rank performance indicators 422 and 424 of the users 109a and 109b based on the first and second performance parameters.
The method 500 may include, at action 512, displaying the leaderboard. For example, the consoles 122a and 122d of the treadmills 120a and 120d may display the leaderboard 420b along with the frame 400b of the video of the video workout program.
The method 500 may include, at action 514, detecting an irregularity in the first performance parameters of the first user. In some embodiments, the action 514 may include detecting that the video workout program was manually paused on the first exercise machine, detecting that an incline of the first exercise machine was manually decreased during the execution of the video workout program on the first exercise machine, detecting that a resistance of the first exercise machine was manually decreased during the execution of the video workout program on the first exercise machine, detecting that a speed of a running belt of a first treadmill was manually decreased during the execution of the video workout program on the first treadmill, detecting that the first user unexpectedly stepped off of a running belt during the execution of the video workout program on a first treadmill, detecting that the first user manually overrode control by the exercise machine control commands of the video workout program of the one or more first moveable members of the first exercise machine during the execution of the video workout program on the first exercise machine, detecting that a current performance of the workout by the first user is inconsistent with past performance of one or more workouts by the first user, or some combination thereof. In some embodiments, detecting that the first user unexpectedly stepped off of a running belt during the execution of the video workout program on a first treadmill may include employing a camera at the first treadmill to automatically capture one or more images of the first user unexpectedly absent from the running belt, employing a heart rate monitor to automatically detect an irregular decrease in a heart rate of the first user, or employing a current sensor on the electric motor of the first treadmill to automatically detect an irregular decrease in a current drawn to drive the electric motor, or some combination thereof. In some embodiments, detecting that a current performance of the workout by the first user is inconsistent with past performance of one or more workouts by the first user may include accessing prior performance parameters associated with prior workouts of the first user (which may be stored on one or more of the devices of
In some embodiments, detecting the irregularity in the first performance parameters of the first user at action 514 may include double verifying the irregularity through a combination of any two or more of the foregoing. For example, detecting the irregularity may include both employing a speed sensor operably coupled to the electric motor to detect that expected fluctuations in a speed of the electric motor are absent and employing a microphone at the first treadmill to detect that expected sounds indicative of the first user running on the first treadmill are absent. The combination of absence of expected fluctuations in speed and absence of expected sounds indicative of running may double verify the irregularity.
The method 500 may include, at action 516, updating the leaderboard to include an irregularity flag associated with the first performance indicator of the first user. In some embodiments, this irregularity flag may indicate the irregularity in the performance of the first user during the workout. In some embodiments, the irregularity flag may include a colored shape (e.g., a red square or a yellow circle) displayed with the first performance indicator of the first user. In some embodiments, only irregularities that make the workout easier result in the leaderboard being updated to include an irregularity flag. In other embodiments, only irregularities that make the workout harder result in the leaderboard being updated to include an irregularity flag. In some embodiments, only irregularities that move a user higher on the leaderboard result in the leaderboard being updated to include an irregularity flag (e.g., if the leaderboard is ranked based on average speed, and the user manually decreases their speed, even though the workout becomes easier for the user, the user will move lower on the leaderboard due to their slower speed so no irregularity flag may be displayed). In some embodiments, any manual adjustment of the exercise machine (e.g., when the exercise machine is placed in manual mode), instead of allowing the video workout program to automatically adjust the exercise machine, may result in the leaderboard being updated to include an irregularity flag. For example, the console 122a, the local server 116, or the remote server 112, or some combination thereof, may update, at action 516, the leaderboard 420b to include an irregularity flag 427 (as disclosed in leaderboard 420c) associated with the first performance indicator of the user 109a (Luis M.) to indicate the irregularity detected at action 514.
The method 500 may include, at action 518, displaying the updated leaderboard. For example, the consoles 122a and 122d of the treadmills 120a and 120d may display, at action 518, the leaderboard 420c, including the irregularity flag 427 (illustrated as a yellow circle) displayed with the first performance indicators 424, along with the frame 400c of the video of the video workout program.
The method 500 may include, at action 520, storing the irregularity flag associated with the first performance indicator of the first user. In some embodiments, the action 520 may include storing the irregularity flag associated with the first performance indicator of the first user with an archived version of the leaderboard for the video workout program executed on the first exercise machine, and/or with an archived version of the first performance parameters for the video workout program executed on the first exercise machine. For example, the consoles 122a and 122b, the local server 116, or the remote server 112, or some combination thereof, may store, at action 520, the irregularity flag 127 associated with the first performance indicator 424 of the user 109a (Luis. M.) with an archived version of the video workout program. Storing the irregularity flag 127 may allow the irregularity flag 127 to be viewed by all future users in some embodiments (such as during future performances of the video workout program or in any history of the video workout program).
In some embodiments, the method 500 may result in the leaderboard 420b being updated in leaderboard 420c with an irregularity flag 427 for Luis M. For example, while the leaderboards 400a-400c are continuously ranking users based on some performance parameter (e.g., miles run), any irregularities in the performance parameters of the users may be detected, and the leaderboard may be updated with an irregularity flag 427 (e.g., a yellow circle) for users such as Luis M. to indicate the irregularity in the performance of Luis M. during the workout. Displaying Luis M. on the leaderboard 420c with an irregularity flag may lessen or eliminate the frustration and sense of unfairness felt by other users, such as Brent S., who follow the workout prescribed in a video workout program. As such, effectively employing the irregularity flag 427 on the leaderboard 420c may allow Brent S. to have greater trust in the leaderboard rankings, and may allow Brent S. to connect to other users and may make the workout on the treadmill 120d more fun.
Although the actions of the method 500 are illustrated in
Another variation of the method 500 may include receiving the first performance parameters of the first user, the first user being associated with the first exercise machine that executes a video workout program to enable the first user to perform a workout on the first exercise machine. For example, as previously indicated, the treadmill 120a, another exercise machine 120, the local server 116, and/or the remote server 112 may receive the first performance parameters after being gathered by sensors at the first treadmill 120a as part of the action 504. This variation of the method 500 may also include the action 514 of detecting an irregularity in the first performance parameters that indicates a performance of the workout by the first user is different than expected.
In some embodiments, the detecting of the irregularity in the first performance parameters of the first user may include detecting that the first user manually overrode control by exercise machine control commands of the video workout program of one or more first moveable members of the first exercise machine during the execution of the video workout program on the first exercise machine.
In some embodiments, the detecting of the irregularity in the first performance parameters of the first user may include at least one of: detecting that a difficulty of the workout is less than an expected difficulty of the workout due to a manual adjustment of an operating parameter of the first exercise machine, detecting that the first user has at least temporarily ceased performance of the workout while the video workout program continues to execute on the first exercise machine, or detecting that the first user is impersonating an expected user during the execution of the video workout program on the first exercise machine. Detecting that the difficulty of the workout is less than an expected difficulty of the workout due to a manual adjustment of an operating parameter of the first exercise machine may include at least one of: detecting that the video workout program was manually paused on the first exercise machine, detecting that an incline of the first exercise machine was manually decreased during the execution of the video workout program on the first exercise machine, detecting that a resistance of the first exercise machine was manually decreased during the execution of the video workout program on the first exercise machine, or detecting that a speed of a running belt of a first treadmill was manually decreased during the execution of the video workout program on the first treadmill. Detecting that the first user has at least temporarily ceased performance of the workout while the video workout program continues to execute on the first exercise machine may include detecting that the first user unexpectedly stepped off of a running belt during the execution of the video workout program on a first treadmill (e.g., by employing a camera, a heart rate monitor, or a current sensor). Detecting that the first user is impersonating an expected user during the execution of the video workout program on the first exercise machine may include employing a current sensor on an electric motor of a first treadmill to automatically detect an irregular current drawn to drive the electric motor based on an expected weight of the expected user, employing a camera and facial recognition techniques to automatically detect that a face of the first user does not match an expected face of the expected user, employing a heart rate monitor at the first exercise machine to automatically detect that a heart rate pattern of the first user does not match an expected heart rate pattern of the expected user, employing one or more sensors at the first exercise machine to automatically detect that a biometric signature-which may include at least one of a heart rate pattern, running dynamics (e.g., cadence, ground contact time, left-right variation, and/or vertical oscillation), a fingerprint, an electrocardiogram (ECG) pattern, or a breathing pattern of the first user does not match an expected biometric signature of the expected user, employing a weight sensor on the first exercise machine to automatically detect that a weight of the first user does not match an expected weight of the expected user, or any combination thereof.
In some embodiments, the first exercise machine is one of multiple exercise machines and the method may further include, in response to the detecting the irregularity, updating a leaderboard displayed on displays at the exercise machines to display an irregularity flag associated with a first performance indicator of the first user to indicate the irregularity in a performance of the first user during the workout.

Various modifications to the embodiments illustrated in the drawings will now be disclosed.
In general, some example methods disclosed herein may enable a user ranked on a leaderboard to be displayed with an irregularity flag where some irregularity is detected in the user's performance. For example, when an irregularity in the performance parameters of the user is detected (e.g., detecting that the user manually decreased the incline percentage on their treadmill, resulting in the user no longer fairly competing against other users who maintained their incline percentage at the prescribed percentage), the listing of the user on the leaderboard may be updated to display an irregularity flag (e.g., a red square or a yellow circle) to indicate the irregularity in the performance of the first user during the workout. Displaying any user with detected irregularities in their performance parameters on the leaderboard with an irregularity flag may lessen or eliminate the frustration and sense of unfairness felt by users who follow the workout prescribed in a video workout program.
In some embodiments, each time an irregularity flag is generated for a user, the details that led to the generation of the irregularity flag may be stored and analyzed. This storing and analyzing may result in the generation of a reputation score with regard to irregularities. Thus, each user may have a reputation score generated and continually updated that indicates the extent to which the user typically complies with the prescribed parameters of video workout programs. This reputation score may be affected differently for different types of irregularities (e.g., a user pausing a workout may negatively affect the score much less than a user employing user impersonation or allowing a running belt to run after having stepped away from the machine). This reputation score may then be used as a filter criteria to allow users to exclude users with reputation scores below a certain score threshold from appearing in a leaderboard. This reputation score may be expressed as a percentage, or as a number of stars (e.g., from one star being a bad reputation to five stars being a good reputation). This reputation score may also be displaying in a leaderboard to allow users to be visually compared, or even ranked, based on their reputations. Further, this storing may allow each irregularity flag to be linking to the details that led to the irregularity flag, which may allow users to simply select an irregularity flag in the display of a leaderboard and to then be presented with these details, in a pop-up window for example. Additionally or alternatively, the details that led to the irregularity flag may appear in any general listing of user statistics that are generally linked to the performance indicator of a user listed in a leaderboard. In these embodiments, a process may be established for a user to challenge or appeal the generation of any particular irregularity flag in an effort to remove an irregularity flag from a particular leaderboard. For example, where an irregularity was detected during a workout due to some sort of equipment or communication failure, but the user legitimately performed the workout within the prescribed parameters, the user may appeal to an arbitrator of the subscription service to have the irregularity flag for workout removed, and also to have any negative effect of the irregularity flag removed from the user's reputation score.
In some embodiments, an irregularity flag may include any visually discernable alteration of or addition to a user's entry in a leaderboard where the user's entry includes the user's performance indicators. As examples, an irregularity flag may include a circle, square, triangle, arrow, asterisk, or other shape that is red, yellow, black or other color and is displayed in or near the user's entry in the leaderboard; highlighting applied to some or all of the user's entry in the leaderboard; greying out of some or all of the user's entry in the leaderboard; bolding or other change (e.g., italics, underline, font size) applied to some or all of the text in the user's entry in the leaderboard; a word (e.g., “irregular”) or phrase positioned in or near the user's entry in the leaderboard; or other visually discernable alteration of or addition to some or all of the user's entry in the leaderboard, or any combination of the foregoing.
In some embodiments, a variety of different irregularity flags may be employed to represent different types of irregularities. For example, different colors, shapes, or sizes, or some combination thereof, may be employed to represent different types of irregularities. Irregularities may be categorized by severity (e.g., ranging from unintentional behavior to intentional behavior), length of time (e.g., ranging from short to long breaks during the workout), impact (e.g., ranging from minimum to maximum impact of the irregularity on movement within the rankings in the leaderboard), etc.
In some embodiments, the leaderboard may be displayed to the side of the video in a video workout program, rather than overlaying the video. Further, in some embodiments, the leaderboard may be displayed in a partially-transparent manner to allow the underlying video to be at least partially viewed by the user even with the leaderboard overlaying a portion of the video. Further, the leaderboard may be repositionable by the user and/or may be hidden and unhidden by the user (e.g., by swiping the leaderboard right and left on a touchscreen to hide and unhide the leaderboard).
In some embodiments, multiple users may simultaneously appear with irregularity flags in a leaderboard. Also, where an irregularity is detected that involves multiple users, the irregularity flags of the affected users may be visually linked together (e.g., where multiple users all took a break at the same time and for the same duration during a workout).
In some embodiments, data collected from sensors or a camera to detect irregularities of a user's performance parameters may alternatively or additionally be used to detect the user's cadence, running dynamics, or other information. For example, images or video (e.g., a series of images) generated by a camera at the user's exercise machine may capture a repeating movement pattern of the user's head, such as where the user's head bobs up and down while the user runs on the exercise machine (if it is a treadmill), the user's head moves from side-to-side while the user pedals on the exercise machine (if it is a stationary bike), or the user's head repeats some other motion while the user exercises on some other exercise machine. Image analysis may be performed on the images to determine times when the user's head is at or near one or more movement peaks (e.g., at or near the top and/or bottom of a bob, at or near the leftmost and/or rightmost positions of a side-to-side motion, etc.) from which the user's cadence, magnitude of vertical oscillations (in the case of a treadmill), magnitude of side-to-side sway (in the case of a stationary bike), or other running or exercise dynamics may be determined.
As another example, a speed sensor (e.g., a tachometer) and/or a current sensor operably coupled to an electric motor of a treadmill may be used to detect cadence, ground contact time, and/or left-right variation of a user. In this example, as the user runs on the treadmill, the user's weight may be selectively weighted and unweighted on the running deck with each stride. The user's weight is applied to the running deck after the user's foot makes contact with the running deck and the user's weight slows the speed of the running belt and thus the electric motor, which in turn causes a load spike on the current of the electric motor as the electric motor attempts to maintain its speed. The user's weight is lifted from the running deck after the user's foot is lifted from the running deck and the speed of the running belt returns to its unloaded speed with less current required for the electric motor to maintain its speed. Accordingly, the cadence may be determined from the speed fluctuations and/or the current fluctuations. Ground contact time may be determined from durations of the load spike and/or the speed decrease during each stride. Left-right variation may be determined by comparing odd (or even) ground contact times (or an average thereof) with even (or odd) ground contact times (or an average thereof).
As another example, a microphone at the treadmill and/or an accelerometer operably coupled to the running deck of the treadmill or other portion of the treadmill may be used to detect cadence. In this example, as the user runs on the treadmill, each stride of the user involves a footfall on the running deck of the treadmill. The sound of each footfall on the running deck may be captured by the microphone and/or the impact of each footfall may be detected by the accelerometer. Thus, audio captured by the microphone may be analyzed to determine a time of each footfall and the user's cadence. Alternatively or additionally, a signal generated by the accelerometer may be analyzed to determine the time of each footfall and the user's cadence.
In accordance with common practice, the various features illustrated in the drawings may not be drawn to scale. The illustrations presented in the present disclosure are not meant to be actual views of any particular apparatus (e.g., device, system, etc.) or method, but are merely example representations that are employed to describe various embodiments of the disclosure. Accordingly, the dimensions of the various features may be arbitrarily expanded or reduced for clarity. In addition, some of the drawings may be simplified for clarity. Thus, the drawings may not depict all of the components of a given apparatus (e.g., device) or all operations of a particular method.
Terms used herein and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including, but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes, but is not limited to,” etc.).
Additionally, if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations.
In addition, even if a specific number of an introduced claim recitation is explicitly recited, it is understood that such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” or “one or more of A, B, and C, etc.” is used, in general such a construction is intended to include A alone, B alone, C alone, A and B together, A and C together, B and C together, or A, B, and C together, etc. For example, the use of the term “and/or” is intended to be construed in this manner.
Further, any disjunctive word or phrase presenting two or more alternative terms, whether in the summary, detailed description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” should be understood to include the possibilities of “A” or “B” or “A and B.”
Additionally, the use of the terms “first,” “second,” “third,” etc., are not necessarily used herein to connote a specific order or number of elements. Generally, the terms “first,” “second,” “third,” etc., are used to distinguish between different elements as generic identifiers. Absence a showing that the terms “first,” “second,” “third,” etc., connote a specific order, these terms should not be understood to connote a specific order. Furthermore, absence a showing that the terms “first,” “second,” “third,” etc., connote a specific number of elements, these terms should not be understood to connote a specific number of elements. For example, a first widget may be described as having a first side and a second widget may be described as having a second side. The use of the term “second side” with respect to the second widget may be to distinguish such side of the second widget from the “first side” of the first widget and not to connote that the second widget has two sides.
The foregoing description, for purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention as claimed to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings. The embodiments were chosen and described to explain practical applications, to thereby enable others skilled in the art to utilize the invention as claimed and various embodiments with various modifications as may be suited to the particular use contemplated.
