Various embodiments of a treadmill system (e.g., exercise device system) are described below. In the course of this description, reference will be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
Various embodiments now will be described more fully hereinafter with reference to the accompanying drawings. It should be understood that the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout.
In various embodiments, a treadmill system (i.e., an ambulation simulation system) may include one or more custom treadmill hardware devices and one or more accompanying pieces of software which may, for example, be configured to work in tandem to simulate one or more virtual terrains within a game on a physical treadmill. The system may, for example, be utilized in one or more sport training, entertainment, rehabilitation, and other contexts. In various embodiments, the system is configured to generate custom game-terrains for walking, hiking, running, etc.
In various embodiments, the system is configured to utilize any suitable rapid incline/decline lifting system described herein (e.g., described above in the context of the bicycle riding system). In this way, the system is configured to simulate rolling hills, sudden drop-offs, and other features. In particular embodiments, in addition to gestures, the system may be configured to identify a position of a user within a width of the treadmill belt in order to provide input in order to navigate within the game. For example, the system may be configured to enable the user to sidestep rocks and other obstacles within the game by moving to one side of the belt or the other while running/walking. In still other embodiments, the system is configured to enable the user to walk along narrow portions of a virtual path (e.g., across a log) by remaining centrally positioned on the belt. As such, the system may be configured to provide a more realistic/immersive running/walking experience than a traditional treadmill that would not be capable of such rapid incline changes and would generally be operated at a consistent speed for the duration of an exercise. In particular embodiments, the treadmill may include a centralized pivot point (e.g., as opposed to a pivot adjacent a rear of the treadmill) to facilitate lifting and lowering of the front and/or rear of the treadmill to increase or decrease a level of incline of the treadmill. The system may further be configured to enable a treadmill to decline below a flat surface (e.g., to simulate downhill walking and/or running).
In still other embodiments, a bicycle riding system, according to various embodiments, is configured to simulate a substantially realistic bicycle riding experience on a substantially stationary platform. The system may, for example, include a bicycle riding device configured to support a bicycle while the bicycle riding device adjusts a position and orientation of the bicycle (e.g., the front of the bicycle, the rear of the bicycle, etc.). In particular embodiments, the system may be configured to manipulate one or more bicycle support mechanisms (e.g., rollers) via a combination of one or more motors and other components in order to adjust a position, angle, relative position, height, slope, slant, etc. of each bicycle support mechanism (e.g., for both the front and rear tires). In particular embodiments, the system is configured to manipulate a bicycle support surface based on terrain data. The system may, for example, be configured to adjust a simulated position and orientation of a supported bicycle based on terrain data that corresponds to a virtual terrain. The system may further manipulate the simulated bicycle position based on pedal speed, handlebar angle, lean of the rider, etc. In various embodiments, the system includes a virtual simulation in addition to a physical simulation, in which an avatar representing the rider traverses a terrain while the rider experiences changes in terrain on the bicycle riding device. Various concepts related to particular embodiments of a bicycle riding system are discussed more fully below.
In any other embodiment described herein, an exercise device system may be configured to perform any function described herein in the context of one or more other exercise devices. These may include, for example, Jacob's ladder, climbing wall, rowing apparatus, etc.

The Software 222 may also reside, completely or at least partially, within the Main Memory 204 and/or within the Processing Device 202 during execution thereof by the Computer 200—the Main Memory 204 and the Processing Device 202 also constituting computer-accessible storage media. The Software 222 may further be transmitted or received over a Network 115 via a Network Interface Device 208.

As may be understood in light of this disclosure, a treadmill system 1000 may include a treadmill 800, which may, for example, include a display device 210 and one or more imaging devices 900 (e.g., and/or any suitable input device or combination of input devices). In particular embodiments, the treadmill 800 may include any suitable treadmill, which may, for example, comprise any suitable belt-driven simulated running surface.
In particular embodiments, any treadmill system described herein (e.g., as discussed herein) may be integrated into a virtual terrain simulation system. As may be understood in light of the systems described herein, a treadmill system may provide one or more system inputs and system outputs to the virtual terrain simulation system by, for example: (1) providing system input to the virtual terrain simulation system such as requests for changes in speed, direction, incline, etc.; and (2) provide one or more system outputs by, for example, modifying a belt speed, belt angle, etc. in response to one or more conditions within the virtual terrain simulation systems.
In particular embodiments, the virtual terrain simulation system may include a mixed reality system in which a user of the treadmill system may interact with a virtual environment by providing input to the system and experiencing physical feedback through manipulation of one or more treadmill mechanisms while the user is using the treadmill. In particular embodiments, the user may view the virtual terrain system while on the treadmill using a suitable display screen, virtual reality headset, etc. In various embodiments, the system may provide a more engaging, realistic user experience for a user of a treadmill (e.g., in contrast with a traditional exercise class). In particular embodiments, a virtual camera may travel through the virtual environment based on both: (1) user inputs (direction change); and (2) treadmill settings (e.g., such as speed) such that the system displays (e.g., on the display screen 210) a substantially first-person view as the virtual camera traverses the virtual terrain. In this way, a user of the treadmill may experience a realistic walking and/or running through the virtual terrain.
In particular embodiments, the treadmill may include one or more lifting mechanisms. In some embodiments, the one or more lifting mechanisms are configured to incline and/or decline a front or rear of the tread (e.g., and/or both the front and the rear) in order to modify an angle of the tread in order to simulate uphill and/or downhill walking/running. In particular embodiments, the system is configured to modify an incline and/or decline level of the treadmill based on one or more changes in terrain of a virtually generated terrain while the system is displaying the terrain on a display screen. For example, as a user's avatar encounters a virtual terrain that has a particular incline level, the system may be configured to automatically modify an incline of the treadmill in response (i.e., the system may be configured to automatically modify the incline based on the incline of the virtual terrain). In this way, the system may be configured to simulate, via physical manipulation of the tread, a running/walking/jogging experience that substantially mirrors the terrain as a user's avatar is traversing through the virtual terrain (e.g., and the system displays a first-person view of the movement through the terrain on the display screen).
Various functionality of the treadmill system 1000 may be implemented via various system modules. The system, when executing certain steps of such modules, may be configured to receive terrain and sensor data and, in response, send one or more control signals to one or more system components in order to manipulate a position, height, angle, or other orientation of an exercise device (e.g., treadmill). The system may perform the operations described in an order other than those in which they are presented in the various embodiments described herein. Various other embodiments of the system modules may perform steps in addition to those described or omit one or more of the described steps.
The system continues, at Step 420, by receiving one or more pieces of sensor data and/or user input data. The one or more pieces of sensor data may, for example, include one or more pieces of sensor data related to a position of one or more components of a bicycle ridden by a rider on a bicycle riding device. For example, the system may use one or more encoders, accelerometers, gyroscopes, or other suitable sensors/devices to determine, for example: (1) running speed; (2) angle of the rider/runner relative to the exercise device; (3) handlebar angle (e.g., in embodiments in which the exercise device includes a bicycle); (4) pose of the rider/runner; (5) tilt of a bicycle relative to the bicycle riding device (e.g., in embodiments in which the exercise device comprises a bicycle); and/or (6) any other suitable sensor data.
In various embodiments, the one or more pieces of sensor data, may, for example, include image data (e.g., received from one or more imaging devices). In particular embodiments, the treadmill system is configured to enable a user to control one or more features of the system using one or more physical gestures (i.e., as opposed to providing physical input via one or more physical controls such as buttons, knobs, levers, etc.). For example, the system may be configured to identify particular user gestures and perform one or more actions in response to an identified gesture. In various embodiments, the system may be configured to associate particular actions with respective gestures and to perform the associated action in response to identifying the respective gesture. In some embodiments, the particular actions may include, for example: (1) speeding up the tread; (2) slowing down the tread; (3) changing an orientation of an avatar relative to a virtually generated terrain (e.g., as discussed more fully herein); (4) causing the avatar to turn to the left and/or right; (5) causing the avatar to avoid one or more obstacles on the virtual terrain; (6) etc.
In various embodiments, gestures that may be associated with particular actions may include, for example: (1) raising or lowering a user's hand; (2) placing one of the user's limbs in a particular orientation; (3) changing the user's position relative to a width of the tread (e.g., moving side to side); (4) jumping; (5) lifting a user's knee; (6) increasing or decreasing the user's running speed; and/or (7) any other suitable action which the system may be configured to identify.
In particular embodiments, as described herein, the treadmill system comprises one or more imaging devices 900 configured to generate a skeletal mapping (e.g., a substantially instantaneous skeletal map) of a user in order to identify one or more gestures performed by the user (e.g., based at least in part on a pose of the skeletal mapping). In various embodiments the one or more imaging devices may include any imaging device configured to identify key points in order to generate a skeletal mapping of a user (e.g., a Microsoft Kinect, Intel Realsense, iPhone, iPad, etc.). In other embodiments, the imaging device may be placed to track a particular user feature (e.g., foot, ankle, knee, leg, etc.). In some embodiments, the system is configured to determine user body positioning data based on one or more images (e.g., video images), one or more infrared images, etc. As may be understood from
In various embodiments, the system is configured to enable the user to create gestures by performing particular movements. In some embodiments, a gesture may comprise a motion or pose by a user that the system is configured to capture as image data and parse for meaning. In various embodiments, particular gestures may include dynamic gestures, which may, for example, comprise a motion (e.g., lifting an arm at a particular speed, nodding a head, etc.). In still other embodiments, a gesture may include a static gesture, such as holding an arm up at a ninety-degree angle (e.g., to indicate a desire to stop the treadmill). In particular embodiments, a gesture may comprise more than one body part, such as clapping the hands together. In various embodiments, the system is configured to interpret any particular gesture as any particular user input (e.g., a first gesture may be associated with a first input type or action, a second gesture may be associated with a second input type or action, etc.). In particular embodiments, the system is configured to enable a user to assign particular action types or inputs to particular gestures.
In particular embodiments, the system is configured to interpret particular gestures as a system input. Gestures may be used for input in a general computing context. For example, as discussed above, particular gestures may correspond to particular movements of a user's avatar within a game (i.e., virtual terrain). Still other movements and/or gestures may correspond to particular settings or changes to settings for the treadmill or other exercise device (e.g., speed, elevation/incline, etc.).
In still other embodiments, the system may utilize one or more additional components in order to track one or more aspects of a user's body (i.e., movement, positioning, etc.) in order to determine one or more user actions (e.g., using one or more additional sensors or combination of sensors). The system may, for example, provide one or more tracking devices (e.g., comprising one or more accelerometers, gyroscopes, etc.) for placement on a particular portion of the user's body (i.e., one or more wrists, one or more ankles, around the user's chest, etc.). The one or more tracking devices may be configured to communicate with the system using any suitable wireless protocol (e.g., Bluetooth, zigbee, wireless LAN, NFC, etc.)
In various embodiments, each of the one or more motion trackers are configured to determine motion data for a respective portion of the user's body on which the respective device is placed and relays the motion data to the system. The system may be configured to receive the motion data from the trackers and, in response, cause the treadmill system to modify one or more settings based on the motion data (e.g., an incline level of the treadmill, a speed of the treadmill, etc.). In still other embodiments, the system is configured to receive the motion data from the trackers and, in response, provide input to a connected gaming environment in which an avatar representing the user is traversing a virtual terrain (e.g., by modifying a direction of the avatar within the virtual terrain, causing the avatar to take one or more actions within the virtual terrain, etc.).
In particular embodiments the system is configured to use motion data received from one or more tracking devices in combination with other data (e.g., imaging data, pressure data from one or more pressure sensors, etc.) in order to determine one or more responsive actions (e.g., one or more responsive actions to cause the treadmill or other device to take or to use as one or more inputs in a virtual game).
In some embodiments, the system may include one or more force sensors (e.g., one or more accelerometers, one or more pressure sensitive resistors, etc.) embedded in a deck of the treadmill. In this way, the system may be configured to triangulate a position of a user's foot upon impact of the treadmill's belt. The system may use impact data for each foot to determine, for example: (1) foot position; (2) stride length; (3) foot pressure (e.g., impact pressure); (4) etc. In various embodiments, the system may be configured to monitor pressure changes in each foot, for example, in order to monitor physical therapy progress, muscle imbalances, etc.
In some embodiments, the treadmill may include one or more pressure sensors on the belt, which may, for example, be configured to determine user gait information related to a position of a user's foot while walking/running. The system may, for example, be determined to identify a weight distribution of a user's foot on the tread. This may, for example, enable a user to trial a pair of footwear and otherwise determine which of one or more different types of footwear are most suitable based on the user's gait (e.g., based on different levels of arch support, different cushioning, etc.).
In various embodiments, the system is configured to merge data received from one or more cameras in addition to one or more pressure sensors and/or one or more tracking bands. For example, the system may be configured to determine a body angle based on data received from one or more sensors. As may be understood by one skilled in the art, as a user's running speed increases, the user may modify an angle of their body (e.g., such that their legs impart more thrust against the support surface at a more severe angle than while walking). In particular embodiments, the system is configured to determine stride length, in addition to ‘hang time’ (e.g., an amount of time in the air between foot falls). In various embodiments, the system may use hang time data to identify inefficiencies in a user's running motion (e.g., because too much time between steps may indicate a loss of efficiency).
In particular embodiments, the system is configured to track a respective position (e.g., and/or change in position) of each of the user's feet as the user is running/walking on the treadmill. The system may, for example, track the change in position and/or impact of each foot on the belt based on feedback from the one or more motion tracking devices and/or force sensors worn by the user. The system may then be configured to substantially automatically adjust a belt speed of the treadmill (e.g., on-the-fly) as the user increases or decreases their speed. For example, the system may be configured to monitor a change in position of each foot and cause the motor driving the belt to advance a distance based on the user's instantaneous stride length (i.e., of each leg). In this way, the system may be configured to enable a user to adjust to any changes in terrain (i.e., incline, etc.) that the user may encounter while using the treadmill without having to provide any input to increase or decrease the belt speed (e.g., gesture input, button input, etc.). As the user's stride length increases, for example, the system may automatically increase the speed of the treadmill. In response to measuring a decrease in the user's stride length, the system may be configured to decrease the speed of the treadmill.
Returning to Step 430, the system is configured to analyze the terrain and sensor data. The system may, for example, be configured to analyze the data to determine a position of an avatar that represents the rider (e.g., runner) within the terrain (e.g., a substantially instantaneous position). The system may further analyze the terrain and sensor data to manipulate a location of an avatar (e.g., and/or virtual camera indicating what the avatar is viewing from a first person perspective) within the terrain. The system may then display a current image form the virtual camera on the display device.
At Step 440, the system is configured for, in response to analyzing the terrain and sensor data, determine a desired orientation of the exercise device based on the terrain and sensor data. The system may, for example, determine the desired orientation based on the physical terrain data and one or more sensor-determined aspects of the exercise device (e.g., or the user on the exercise device). For example, the system may determine a desired orientation of the exercise device (e.g., treadmill) based on an orientation that most closely simulates the terrain.
In particular embodiments, as part of the analysis, the system is configured to record information about a user's gait characteristics, cadence, etc. in order to identify changes over time. For example, a user rehabilitating a leg injury may initially walk with a limp. The system may be configured to identify, based on the user's skeletal mapping, one or more characteristics of the user's limp such as: (1) the user favoring one particular leg over another; (2) the user leaning to one side; (3) one or more limits to the user's speed or ability to navigate certain levels of incline, etc. In various embodiments, the system may be able to track improvements to the user's gait over time in order to identify completion of a user's rehabilitation from an injury that caused the limp.
In particular embodiments, the system is configured to track a respective position of each of the user's feet as the user is running/walking on the treadmill. The system may then be configured to substantially automatically adjust a belt speed of the treadmill (e.g., on-the-fly) as the user increases or decreases their speed. For example, the system may be configured to monitor a change in position of each foot and cause the motor driving the belt to advance a distance based on the user's instantaneous stride length (i.e., of each leg). In this way, the system may be configured to enable a user to adjust to any changes in terrain (i.e., incline, etc.) that the user may encounter while using the treadmill without having to provide any input to increase or decrease the belt speed (e.g., gesture input, button input, etc.). As the user's stride length increases, for example, the system may automatically increase the speed of the treadmill. In response to measuring a decrease in the user's stride length (e.g., at a higher incline level), the system may be configured to decrease the speed of the treadmill.
In particular embodiments, the instantaneous speed adjustments may provide the user with more control over the experience, without having to provide any system input. The system may, for example, be configured to determine a real-time movement speed based in response to completion of a first step as the user drives off of a particular foot. The system may, for example, identify a new forward motion based on a lifting of a knee and/or foot, which may, for example, signal a new forward step by the user. In some embodiments, the system is configured to track user-specific characteristics in order to predict and/or identify a single stride length (e.g., knee position, hand position, arm pumping speed, etc.). In some embodiments, the system may similarly identify other actions by the user such as reversing (i.e., walking/running backwards), crouching, exaggerated longer strides to avoid obstacles, bunny hops to clear certain obstacles, etc.
In still other embodiments, the system is configured to automatically adjust a belt speed in response to a change in incline caused in response to position change within a virtual terrain. For example, the system may automatically reduce a belt speed as the incline of the treadmill increases. In still other embodiments, the system may comprise one or more mechanical breaks (e.g., electromagnetic breaks) configured to prevent slipping of the belt during incline and/or decline. For example, one or more rotors and/or motors may include one or more suitable breaking mechanisms.
In some embodiments, the treadmill may include one or more pressure sensors on the belt, which may, for example, be configured to determine user gait information related to a position of a user's foot while walking/running. The system may, for example, be determined to identify a weight distribution of a user's foot on the tread. This may, for example, enable a user to trial a pair of footwear and otherwise determine which of one or more different types of footwear are most suitable based on the user's gait (e.g., based on different levels of arch support, different cushioning, etc.).
Next, at Step 450, the system is configured to send one or more control systems to one or more exercise device components (e.g., treadmill components) based on the determined orientation. The system may, for example, activate one or more motors to adjust a belt speed of the treadmill. In still other embodiments, the system is configured to modify a position of a rider's avatar within a displayed version of the terrain based on the runner's inputs, lean, etc. The system may be further configured to cause the runner's avatar to traverse the terrain based on the sensor data (e.g., by turning, etc.) which may, in turn, adjust the terrain based on where the runner travels within the terrain. In this way, the system may be configured to enable the runner to ‘freely’ move within the terrain, while the treadmill (e.g., exercise device) adjusts the simulated terrain that the runner experiences based on the runner's position and orientation within the terrain, as well as the turning, leaning, etc. that the runner performs (e.g., and is determined by the sensor data or user input data). In other embodiments, the system may automatically activate a lifting mechanism configured to adjust an incline of the exercise device (e.g., the treadmill) to substantially match (e.g., correspond to) a level of incline based on a current position of a user's avatar within a virtual terrain.
In particular embodiments, the treadmill may include one or more lifting mechanisms. In some embodiments, the one or more lifting mechanisms are configured to incline and/or decline a front or rear of the tread (e.g., and/or both the front and the rear) in order to modify an angle of the tread in order to simulate uphill and/or downhill walking/running. In certain embodiments, such as those shown in
In particular embodiments, a treadmill may comprise one or more lifting mechanisms configured to lift and lower a treadmill belt (e.g., adjust an angle of the treadmill belt relative to a support surface) by adjusting a height of the front and rear of the treadmill about a pivot point. In particular embodiments, the pivot point may be positioned in any suitable location between the front and rear of the treadmill (e.g., positioned somewhat centered along a length of the belt). In the embodiment shown in these figures, the treadmill includes a safety handrail and bar in front of and to either side of the runner. In the embodiment shown in this figure, the treadmill does not include a console with input controls. As discussed more fully herein, the system may employ gesture control through one or more imaging devices. In this way, the system may provide a safer experience by not requiring a user to look down in order to press a button to control a speed or incline of the treadmill. In this way, the user may continue looking ahead to make such setting adjustments, which can avoid unsafe situations resulting from a user looking down or struggling to find a desired button to press (e.g., which is particularly unsafe at an incline or when running at higher speeds).
In particular embodiments, a seesaw arrangement may provide a central pivot point, providing a moment arm to the motor while decreasing a moment arm caused by the load (e.g., the runner). In this way, an apparent load on a motor providing incline and decline to the running surface may be reduced by the system.
As shown in
In various embodiments the cable may further include a chain tensioner or other mechanism for integrating the cable with one or more lengths of chain. In particular embodiments, each of the one or more motors are configured to release and/or pull the cable as necessary to enable the respective cable portions to hold the belt at a desired angle with sufficient force to support a runner on the surface of the belt 705 while the belt is running and maintained at the desired angle.
In particular embodiments, the see-saw arrangement described herein may provide a faster change in angle for the belt (e.g., faster than traditional systems which rely on one or more linear actuators to lift a front portion of the treadmill). In particular embodiments, the treadmill system comprises a system of one or more cables, chains, combination of cables and chains, or other suitable mechanism configured to cooperate to cause an incline and/or decline of a running platform (e.g., belt).
In various embodiments, the position of the pivot point 708 may reduce a load on the one or more motors while the belt 705 is in an incline or decline position. In a particular embodiment, the pivot point 708 may be positioned at least about ⅔rd of the length of the belt from a front end of the treadmill.
In particular embodiments, a position of the pivot point and the load of the runner are configured to minimize a load on one or more motors that are causing the running platform to maintain a particular position (e.g., angle relative to the support surface). In particular embodiments, a position of the pivot point may be adjusted to modify a motor load and an effect on a lever arm created by a runner's position with respect to the pivot point. The system may, for example, be configured to utilize different pivot point positions for different applications (e.g., treadmill, rowing machine, etc.). In still other embodiments, the pivot point (e.g., position of the pivot point) is adjustable.
In particular embodiments, the treadmill system is designed such that a runner using the treadmill would have his or her weight substantially centered above the pivot point while running. In a particular embodiment, a drive motor for the belt may be configured to transfer rotation (e.g., via one or more belts) to a shaft at the pivot point, which may then be configured to transfer rotation to either the front roller or a back roller to drive a rotation of the running surface belt (e.g., treadmill surface).
In particular embodiments, the treadmill system comprises an independent right and left running belt (e.g., one belt for each foot of a runner). As may be understood from
In the embodiment shown in
In particular embodiments, the system comprises a quick-cassette system configured to enable a user to change from one implementation to another substantially on-the-fly. For example, the system may comprise one or more rollers around which a user can place a desired deck type (e.g., treadmill, Jacob's ladder, climbing wall, rowing apparatus, etc.). The user may, for example, remove a particular cassette type from the lifting mechanism and rollers and replace it with a desired cassette type. The system may, for example, include a quick release mechanism for detaching a currently installed cassette type in favor of another type.
In particular embodiments, the rowing simulation system may incorporate various aspects of the treadmill system described herein. For example, in particular embodiments, the treadmill belt is configured to move back and forth (e.g., as opposed to continuously in one direction) in order to simulate rowing motion. In various embodiments, the system is configured to adjust a rowing force by modifying a pulling force required by the user against the one or more pulleys in addition to the push and pull of the belt. In still other embodiments, the system would be configured to implement a more realistic paddling system by, for example: (1) providing an electromagnetic rowing joint configured to control oar resistance, which may, for example, determine position and velocity with six degrees of freedom; (2) determining an angle of a user's hand while rowing (e.g., at various positions during a stroke); and (3) use hand and oar angle data to more accurately affect input to a virtual rowing simulation based on rowing power, angle, etc.
In a particular embodiment, the system may, for example, translate a deeper stroke at a particular angle with respect to the water with a greater forward thrust in a virtual rowing simulator. In particular embodiments, the system is configured to enable independent hand motion (e.g., in the context of a kayak simulation). In various embodiments, each handle provides independent feedback, which may, for example, require a user to provide more precise input to row in a straight line (e.g., than a traditional rowing motion with a single pulley for example). In some embodiments, the system comprises multiple pulleys that are independently operated by respective handles (e.g., via one or more respective stanchions). The rowing simulation may be further understood from
A bicycle riding system, according to various embodiments, is configured to simulate a substantially realistic bicycle riding experience on a substantially stationary platform. The system may, for example, include a bicycle riding device configured to support a bicycle while the bicycle riding device adjusts a position and orientation of the bicycle (e.g., the front of the bicycle, the rear of the bicycle, etc.). In particular embodiments, the system may be configured to manipulate one or more bicycle support mechanisms (e.g., rollers) via a combination of one or more motors and other components in order to adjust a position, angle, relative position, height, slope, slant, etc. of each bicycle support mechanism (e.g., for both the front and rear tires). In particular embodiments, the system is configured to manipulate a bicycle support surface based on terrain data. The system may, for example, be configured to adjust a simulated position and orientation of a supported bicycle based on terrain data that corresponds to a virtual terrain. The system may further manipulate the simulated bicycle position based on pedal speed, handlebar angle, lean of the rider, etc. In various embodiments, the system includes a virtual simulation in addition to a physical simulation, in which an avatar representing the rider traverses a terrain while the rider experiences changes in terrain on the bicycle riding device
As may be shown in
In various embodiments, the one or more motors 330 are configured extend and retract respective cables 350 (e.g., strings, chains, ropes, or other suitable substantially rigid members), which may, for example, be operably connected to both a respective motor of the one or more motors 330 and the front wheel support 312 via one or more pulleys 340. As may be understood in light of this disclosure, the one or more motors 330 may be configured to manipulate a position of the front wheel support 312 by extending and retracting different support cables 350 to cause relative movement of different corners of the front wheel support 312. In this way, the bicycle riding device 300 may be configured to manipulate a height and angular position of the front wheel support 312. In still other embodiments, the bicycle riding device 300 may utilize any other suitable mechanism for manipulating a height, position, and angle of the front wheel support. The system may for example, utilize one or more linear actuators (e.g., positioned on respective corners of the front wheel support), one or more levers, and/or any other suitable mechanism or combination of mechanisms to affect a desired movement and orientation of the front wheel support. As may be understood from

In various embodiments, the front wheel manipulation mechanism 410 includes a first roller manipulation mechanism 414 and a second roller manipulation mechanism 416. As may be understood in light of this disclosure, the first and second roller manipulation mechanisms 414, 416 are configured to manipulate a position of respective ends of the at least one roller 412. For example, the first roller manipulation mechanism 414 may be configured to raise and lower a first end of the at least one roller 412, and the second roller manipulation mechanism 416 may be configured to raise and lower a second end of the at least one roller 412. In this way, the front wheel manipulation mechanism 410 may be configured to provide a lifted, lowered, and/or slanted riding surface for the front tire of the bicycle.
In various embodiments, a rider of the bicycle may need to steer the front tire to compensate for the tilt of the at least one roller 412 while riding the bicycle on the bicycle riding device (e.g., in order to maintain the front tire on the at least one roller 412). In various embodiments, each of the first roller manipulation mechanism 414 and the first roller manipulation mechanism 416 may include one or more motors, pulleys, cables, brackets or other suitable mechanisms for affecting the desired lifting and lowering of the at least one roller 412. In particular embodiments, the first roller manipulation mechanism 414 may, for example, include a spring configured to at least partially dampen and/or neutralize a load on the at least one roller 412 (e.g., due to the weight of the bicycle and rider). In some embodiments, the spring (e.g., one or more springs) may be configured to cooperate with the one or more motors to facilitate a smoother lifting of either end of the at least one roller 412. In still other embodiments, the spring is configured to at least partially compress when the bicycle is lowered such that when the one or more motors are lifting the at least one roller back up 412, the force of the spring cooperates with the one or more motors to provide a lifting force to the first end of the at least one roller. In various embodiments, the first and second roller manipulation mechanisms may be substantially structurally similar (e.g., identical).
Referring again to
In various embodiments, the system may comprise one or more sensors configured to detect a pedal rate (e.g., pedal power) of the bicycle (e.g., using one or more encoders in the first and/or second rollers 422, 424, one or more accelerometers, etc.). In particular embodiments, the system may comprise one or more controllers configured to cause the one or more motors to cause one or both of the first and second rollers 422, 424 to rotate at a rate based at least in part on a determined rate of pedaling of the bicycle. In this way, the system may be configured to compensate for a lower pedal rate with an ‘assist’ provided by the one or more motors and rollers.
In particular embodiments, the bicycle riding device 400 may include any suitable combination of wheel support and/or manipulation mechanisms described herein. For example, the bicycle riding device 400 may include a rear wheel manipulation mechanism 420 that is structurally similar to (e.g., identical to) the front wheel manipulation mechanism 410 described above. In still other embodiments, the bicycle riding device 400 may include a front manipulation mechanism 410 that is structurally similar to (e.g., identical to) the rear wheel manipulation mechanism 420 described above. In still other embodiments, the bicycle riding device may include any suitable combinations of front and rear manipulation mechanisms described herein.
Turning to
In particular embodiments, any of the rollers described herein may be configured to simulate different riding surfaces. For example, the one or more rollers may include one or more knobby rollers, for example, to simulate gravel or other surfaces. In still other embodiments, the system may comprise interchangeable rollers, which may, for example, comprise different surfaces (e.g., different surface configurations, different surface coefficients of friction, etc.). In this way, the system may be configured to simulate different surfaces (gravel, sand, wet surfaces, asphalt, dirt, etc.) through combinations of different rollers.
As may be understood from these figures, in various embodiments, the device may include a rear tire support configured to attach adjacent opposing portions of a rear tire axle. In various embodiments the rear tire support is configured to support the bicycle in an upright position. In various embodiments, the rear tire support is configured to traverse between opposing sides of the device (e.g., along one or more shafts). In still other embodiments, the rear tire support is configured to tilt (e.g., up to about 45 degrees). In various embodiments, the rear tire support includes a mechanism for adjusting a maximum tilt of the support. In this way, the system may be configured to enable a rider to lean into a turn without risking having the bike fall over.
In particular embodiments, the system is configured to simulate one or more actions in addition to walking/running on a flat/incline/or declined surface. For example, in a particular embodiment, the system is configured to simulate pushing an object (e.g., such as a sled) by: (1) stopping the rotation of the running belt; (2) directing the player to push the belt through their own force; (3) received rotational input of the belt from the user (e.g., as the user holds one or more hand supports and pushes the belt with alternating feet; and (4) in response to the belt rotation, causing the player's avatar to move within the virtual environment while pushing an object with which the avatar is interacting.
In still other embodiments, the system is configured to simulate jumping by detecting the player being positioned high enough off of the running belt for at least a certain amount of time. The system may identify jumping using one or more pressure sensors, imaging devices, IR sensors, or any other suitable sensor. In particular embodiments, the player may hold onto one or more handrails and support their body weight while lifting their feet at least temporarily off of the running surface to cause their avatar to jump within the virtual terrain and in order to jump in a particular direction forward as well as upwards. In various embodiments, jumping may enable a player to control movement of their avatar within the virtual environment to traverse over obstacles, etc.
In still other embodiments, the system is configured to initiate a climbing simulation by: (1) increasing the incline to a maximum height; and (2) reducing a belt speed to a low speed or no speed. In this way, the system may simulate a slow climb, force the user to provide all of the force to move the belt on their own, etc. In yet another embodiment, the system may be configured to simulate wading (e.g., through water or another substance within the virtual environment) by, for example: (1) decline to the lowest angle based on the treadmill configuration; (2) set the belt speed to zero; and (3) receive user input causing the belt to spin (e.g., through the force of the user's legs). In various embodiments, the system may be configured to automatically increase an incline in response to a user increasing a force provided to the belt (e.g., as if the user were wading out of the environment). In still other embodiments, the system is configured to re-lower the treadmill in response to the user slowing down the force of input or stopping (e.g., to simulate sinking).
In still other embodiments, the system may be configured to simulate walking through shallow water by, for example, alternatingly slightly lowering and slighting raising the belt. This may for example, simulate a user needing to raise their feet higher to walk through shallow water. In additional embodiments, the system is configured to identify a particular user gesture input and interpret the input as a grabbing motion. This may enable the user to interact with objects within the virtual environment by making a particular gesture, positioning their hand in a particular manner, etc. Once grabbing an object, the user may, for example, perform an additional gesture in order to indicate pulling, throwing, or taking other actions with regard to the object in the environment. In this way, the system may require the user to move their body in particular ways in order to interact with the virtual environment. This may include, for example, collecting objects within the environment (e.g., by reaching their hand in a direction of the object relative to their avatar), avoiding particular elements within the environment, etc.
In various embodiments, the system is configured to use one or more machine learning techniques to identify particular player behavior based on the player's past interaction with and response to different environmental conditions. For example, the system may identify one or more patterns in how a user approaches a hill with a particular incline (e.g., in terms of speeding up and slowing down) and automatically modify a speed of the treadmill in response to a user approaching such a feature in the virtual environment. This may enable the user to interact with the environment without having to provide as much input with regard to speed adjustments, etc.
In particular embodiments, the system may be configured to utilize one or more additional forms of user input. For example, in various embodiments, the treadmill system may comprise one or more microphones (e.g., or other transducers for converting sound into one or more electrical signals). In such embodiments, the system may be configured to receive sound input (e.g., audio input) via the one or more microphones. The system may, for example, be configured to receive one or more vocal inputs from a user of the treadmill system.
In various embodiments, the system may be configured to receive and analyze audio (e.g., voice) input in order to interpret particular sounds as system inputs and perform one or more actions in response to those inputs. For example, in a particular embedment, the system is configured to identify one or more audio inputs using one or more natural language processing techniques (i.e., to identify a particular word or series of words in a piece of audio received by the system).
In particular embodiments, the system is configured to integrate with one or more virtual assistants, cloud-based voice services, etc. (e.g., Amazon Alexa, Siri, etc.). In various embodiments, the system is configured to utilize one or more application programming interfaces to leverage one or more cloud-based voice services to identify particular vocal inputs from a user of the treadmill. The system may then be configured to receive an identified command from the cloud-based voice service and perform one or more actions associated with the command.
For example, in various embodiments, the system may store one or more trigger words which may, for example, cause the system to perform a specific action in response to identification of a particular one of the one or more trigger words. In response to a particular excited utterance (e.g., ‘wow’, ‘yikes’, ‘be careful’, etc.), the system may be configured to generate a marker at that location at which the user made the utterance that provides information for other treadmill users when they navigate the virtual terrain in the same area. For example, in response to an utterance that indicates a warning, the system may generate a warning for users to be careful in a particular location (e.g., because of a sudden steep incline or other obstacle at that location). In other embodiments, the system may generate a marker indicating a particular interesting location within the virtual terrain that is worth viewing (e.g., a point of interest, waterfall, etc.).
In various embodiments, the system is configured to combine vocal input of the user with one or more gesture inputs in order to determine a user input. For example, the system may be configured to identify a user vocal input of “I want to take that trail” in combination with a gesture of the user pointing in a particular direction. In response, the system may be configured to cause the user's avatar to ‘snap-to’ a predefined path in the direction in which the user was pointing while giving the vocal command. In this way, the system may enable the user to provide more nuanced input that combines the user's vocal control and gesture inputs, without requiring the user to stop walking/running, push any buttons, etc. The system may, for example, identify user gestures and physical input using any suitable technique described herein.
In particular embodiments, the system may be configured to store location data based on vocal inputs in order to enable a user to easily return to a particular stored location within the virtual terrain (e.g., ‘save this spot for later’, etc.).
In still other embodiments, the system may be configured to receive user input based on one or more electrical signals from the user's brain and/or one or more muscles. For example, the system may be configured to interface with an EEG and/or EMG in to receive electrical brain activity and/or muscle activity. The system may then be configured to interpret particular electrical signals as particular system inputs.
Accessing Existing Trails within a Virtual Terrain
As discussed more fully above, in various embodiments, the system is configured to enable a user of the treadmill system to substantially freely (e.g., freely) navigate a virtual terrain while using gestures and other user input to change directions, speed up, slow down, and traverse the terrain while continuing to run/walk on the treadmill. In particular, the system is configured to enable such free movement while modifying the treadmill itself in response to terrain encountered by the user's avatar. As may be understood in light of this disclosure, by freely moving through the virtual terrain, the user may encounter terrain of varying degrees of difficulty (e.g., steep slopes, rough areas, areas of obstacles to overcome, etc.). As such, various users may desire to travel on predefined trails or paths rather than risking encountering terrain that is above the user's ability level.
In particular embodiments, the system may store predefined running/walking paths (e.g., through the virtual terrain) that enable a user to traverse the virtual terrain without having to provide direction input. In such embodiments, when travelling on a predefined path, the user's avatar may be configured to stay on the predefined path substantially automatically. For example, when travelling along a predefined path, the user may simply run and/or walk at their desired pace while navigating the changes in slope on the path, without having to cause the avatar to turn to the left or right in order to remain on the path.
In various embodiments, the system is configured to display an entrance to one or more paths within the virtual terrain as the user traverses the virtual terrain. In this way, the system may be configured to present a user with pre-set and other stored paths that the user may elect to take (e.g., using one or more voice commands) as the user encounters them. In other embodiments, the system is configured to enable a user to request to ‘snap-to’ the nearest available path. In still other embodiments, the system is configured to: (1) receive a request from the user to travel to a particular location; (2) automatically generate a path from the user's current location to the particular location; and (3) enable the user to travel along the generated path without having to provide directional input. In this way, the system may be configured to enable a user to switch between free-travel and trail-travel substantially on-the-fly. In still other embodiments, the system is configured to generate a requested path based on one or more user preferences. For example, the user may request to travel to a particular location using a path of easy, medium, or hard difficulty. In response, the system may generate the travel from the user's current location to a desired one based on the user's difficulty preference (e.g., avoiding difficult terrain for an easy path, and seeking it out for a hard one). In some embodiments, the system is configured to generate a most direct path to the desired location. In other embodiments, the system is configured to generate the shortest (e.g., in terms of time) path. In still other embodiments, the system is configured to generate a path based on any other suitable factor.
In particular embodiments, the system is configured to enable a user to save a path that they have taken while moving freely through the virtual terrain in order to share the stored path with others. In such embodiments, the system may, in response to a user accessing a path created by a friend or other user, display a ‘ghost’ version of the path-creator's avatar as the second user traverses the path. In this way, the system is configured to enable one user to challenge a second user to take the same path while competing for time, etc.
In particular embodiments, the system is configured to store other data along with user-stored trail data such that other users can relive a first user's journey at a later time, complete with other data beyond the path taken by the user. For example, the system may be configured to store commentary and/or vocal inputs/narration provided by the creator of the trail so that later users that access the stored trail can hear information provided by the first user. In this way, a subsequent user accessing a trail may be able to completely relive a run/walk created by a first user as if the two users were experiencing the run together. In particular embodiments, the system is configured to store a ribbon of user data for a particular generated trail, which may include, for example: (1) location data within the virtual terrain over a particular length of time; (2) time-stamped vocal commentary; (3) time-stamped audio data for music and other ambient sounds heard by the user as the user traversed the virtual terrain to generate the trail; (4) vital signs and other data related to the user (i.e., heart rate); (5) pace data throughout the trail for the user that generated the trail; (6) instantaneous incline data throughout the trail (e.g., so a user deciding whether to select the trail can see how difficult the terrain is); and any other suitable data related to the trail and the creator's experience on it. In various embodiments, the system is configured to display the combined trail data as a ribbon that indicates points of interest, pace, and other data along the entire length of the trail. In some embodiments, the system is configured to provide the ribbon data (e.g., the visual representation of a run) to a medical professional for analysis as part of a physical rehabilitation.
In still other embodiments, the system may use one or more machine learning techniques to track user behavior in order to determine how a user handles particular interactions. For example, the system may be configured to learn a user's habits (e.g., using any suitable machine learning model) with regards to certain obstacles and automatically adjust the system based on those habits. In response to determining that a user typically slows down on a steep hill, the system may, for example, be configured to reduce a belt speed of the treadmill in response to a user reaching an area with a relatively steep incline.
In various embodiments, as described herein, the system is configured to track user data as the user uses the treadmill device. This may include, for example, vital signs and other data related to the user (i.e., heart rate). In particular embodiments, the system may be configured to automatically modify, or recommended modification to a user's path through the virtual terrain based on their heart rate and/or past performance data. For example, the system may be configured to manipulate the difficulty of the terrain that a user encounters (e.g., adjust a user's course through the terrain to include lower incline and/or decline) based on the user's heart rate. For example, the system may identify a target object within the virtual terrain for the user (e.g., based on user input, desired exercise time, desired exercise distance, etc.). The system may then determine, based on the user's heart rate, current distance from the objective, and terrain profile between the current position and the objective that, for example: (1) completing the current track to the desired objective may involve too much exertion for the user based on their ability level; (2) completing the current track to the desired objective may not involve enough exertion based on the user's typical exertion levels; etc. The system may then, in response to a determination discussed above: (1) automatically modify the user's path and/or objective; (2) recommend a modification to the user's path and/or objective (e.g., by displaying a recommended alternate path in the virtual terrain, which may include a more difficult or easier path to the objective); and/or (3) take any other suitable action to harmonize an estimated total activity output for the user with at least one of: (1) the user's typical performance; (2) the user's maximum performance; (3) the user's historical performance; (4) the user's provided desired exertion level; (5) etc.
In particular embodiments, the system is configured to selectively display alternate paths for the user through the virtual terrain, which may correspond to different effort levels required, difficulty to complete, change in altitude, shortest distance, etc. In displaying the alternate paths, the system may be configured to provide data for each path such as, for example: (1) total elevation change; (2) total distance; (3) number of interactions encountered (e.g., water, logs, jumps, etc.); (4) estimated time (e.g., based on current pace, historical average pace, etc.); (5) maximum incline data; (6) maximum decline data; and/or (7) any other suitable data related to any optional path. In this way, the system may be configured to display on screen directions (e.g., in the form of a virtual line or other indicator) that the user can select from (e.g., and follow) in order to achieve their desired goal during a particular activity. In some embodiments, the system may be configured to ‘snap’ the user to the selected line. In other embodiments, the user may need to direct and steer their avatar along the line (e.g., using any suitable input technique described herein). In particular embodiments, the system may generate a user interface indicating an ‘effort’ or ‘power’ level that the user is currently producing. In such embodiments, the system may determine ‘effort’ and/or ‘power’ based on one or more of a user's prior performance metrics (e.g., top speed, average speed, max incline, max decline, average incline, most obstacles encountered and navigated, etc.). In this way, a user can customize a particular activity (e.g., workout) based on their goals for that activity.
In particular embodiments, the system is configured to play one or more sounds as the user traverses the virtual environment. In particular embodiments, the one or more sounds may be based on one or more factors within the virtual terrain such as: (1) location (e.g., proximity to one or more sound-producing features within the terrain such as waterfalls, rivers, wildlife, etc.); (2) running surface within the virtual terrain (e.g., wet pavement causing splashing on footstep, leaves causing crunching, snow, puddles, etc.); and (3) any other suitable factors. In various embodiments, the system may be configured to identify the user's actual footstep on the belt using any sensor or technique described herein, in order to time a sound effect (e.g., crunch, splash, etc.) with the step of the user.
In various embodiments, the system may be configured to play one or more pieces of ambient music that the system is configured to modulate (e.g., automatically) based at least in part on: (1) a user's running/walking pace; (2) a current incline; (3) a proximity to the top of a climb; (4) an appearance within the terrain of a particular feature; (5) etc. In various embodiments, the modulation of the ambient music may include, for example: (1) a change in volume (e.g., up or down); (2) a change in beats per minute; (3) etc. In various embodiments, the system is configured to match a beat per minute of any ambient music to a running pace of the user of the treadmill. In still other embodiments, the system is configured to set a music beat per minute that is just above the running pace of the user. This may, for example, encourage the runner to continue to increase their speed (e.g., and therefore get more out or the run from an exercise perspective).
In particular embodiments, the system is configured to automatically change one or more audio features substantially instantaneously as the user's location, speed, direction, etc. change within the virtual terrain based on any feature described herein. In still other embodiments, the system is configured to cause one or more changes to the treadmill system based on one or more audio cues (e.g., by increasing or decreasing the speed of the belt, such as while the user runs over leaves or in snow, etc.).
In particular other embodiments, in addition to the various exercise devices described herein, the system may be embodied as any of: (1) an arcade machine (e.g., such as an arcade rideable vehicle such as a motorcycle or car; (2) a driving simulator; and/or (3) any other device or system which may benefit from the use of any of the user input system (e.g., gesture control, etc.) or user feedback systems (e.g., physical manipulation of an angle of incline, tilt, speed, etc. of a physical device) described herein. In yet another embodiment, the system may include the use of an arcade gun (e.g., light gun) or other input device configured to provide additional functionality to the system (e.g., such as an embodiment in which a user traverses a virtual terrain using the treadmill while shooting enemies).
In still other embodiments, the exercise device may incorporate any other suitable piece of exercise machinery or be configured to integrate with any other suitable piece of exercise equipment. For example, in any embodiment described herein, the system may include one or more attachment points (e.g., hooks, carabiners, holes, etc.) for attaching one or more cables or other devices which may provide additional exercise functionality to a user. In a particular embodiment, the system may include a pull rope or other pulling mechanism for use by the user when encountering particular environmental features in the virtual environment. In still other embodiments, the system may comprise one or more latching or other mechanisms for attaching one or more pull-up bars or other pieces of equipment. In particular embodiments, the system may include one or more pull up bars coupled to a safety bar of the treadmill device.
In any other embodiment described herein, the system may be configured to interface with or incorporate any other suitable exercise or other device or equipment.
Many modifications and other embodiments of the invention will come to mind to one skilled in the art to which this invention pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. While this specification contains many specific embodiment details, these should not be construed as limitations on the scope of any invention or of what may be claimed, but rather as descriptions of features that may be specific to particular embodiments of particular inventions. Certain features that are described in this specification in the context of separate embodiments may also be implemented in combination in a single embodiment. Conversely, various features that are described in the context of a single embodiment may also be implemented in multiple embodiments separately or in any suitable sub-combination. Moreover, although features may be described above as acting in certain combinations and even initially claimed as such, one or more features from a claimed combination may in some cases be excised from the combination, and the claimed combination may be directed to a sub-combination or variation of a sub-combination. For example, particular embodiments referring to certain components in various positions on the device may, in other embodiments, include other components described herein in any suitable combination.
Similarly, while operations are depicted in the drawings in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed, to achieve desirable results. Additionally, while some steps may be described as occurring in response to (e.g., or at least partially in response to) particular other steps, it should be understood that, in other embodiments, such steps may occur independent of (e.g., or coincident with) one another. In certain circumstances, multitasking and parallel processing may be advantageous. Moreover, the separation of various system components in the embodiments described above should not be understood as requiring such separation in all embodiments, and it should be understood that the described program components and systems may be generally integrated together in a single software product or packaged into multiple software products.
Many modifications and other embodiments of the invention will come to mind to one skilled in the art to which this invention pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the invention is not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for the purposes of limitation. For example, as a user's avatar encounters a virtual terrain that has a particular incline level, the system may be configured to automatically modify an incline of the treadmill in response (i.e., the system may be configured to automatically modify the incline based on the incline of the virtual terrain). In this way, the system may be configured to simulate, via physical manipulation of the tread, a running/walking/jogging experience that substantially mirrors the terrain that a user's avatar is traversing through the virtual terrain.
It should be further understood that any particular feature (e.g., lifting mechanism) described with respect to any embodiment may be implemented in any other embodiment described herein (e.g., or in combination with other lifting mechanisms).
