Alternatively, it can analyze the user's exercise movements as the exercise progresses and provide them visually. Or, it can provide a visual or auditory alarm if the user performs a movement outside a preset range.

[0056] The display (150) can receive user input regarding the operation of the training device (100) from the user. For example, the training device (100) can manage user-specific exercise information by creating user-specific account information. To this end, the training device (100) can output a UI (User Interface) for logging into a user account and receive information required for login.

[0057] The user can select a desired exercise program through the display (150) of the training device (100) or provide an exercise program recommended by the training device (100). To perform the exercise, the user can place both hands on the handle portion (120) and both feet on the footrest portion (130). While performing the exercise, the user can move each handle and each stepper up and down.

[0058] Through a training device (100) according to one embodiment of the present disclosure, a user can perform actions such as mountain climbing or climbing. In particular, through the training device (100), a user can repeatedly perform cross crawl motion actions.

[0059] Meanwhile, the user may receive various exercise programs through the training device (100) according to the present disclosure. The training device (100) may analyze and provide the user's exercise status. For example, the training device (100) may provide a program that alternates between exercise and rest for a preset period of time. At this time, the handle portion (120) and the footrest portion (130) may move according to the preset exercise intensity, number of steps, step height, and number of sets. The display (150) may display the preset information on the screen and display the exercise time and the currently ongoing exercise set. For example, the training device (100) may provide a program that moves according to exercise conditions preset by the user. At this time, the display (150) may display on the screen the major parts of the user's muscle that are activated through exercise.

[0060] In particular, the training device (100) can provide an exercise course so that the user can feel like they are hiking while exercising. For example, the training device (100) may be provided with an exercise course that provides a feeling similar to a hiking course. Depending on the exercise course, at least one of exercise time, exercise intensity, exercise speed, and step height may be set. The training device (100) may provide video content along with the exercise course. The display (150) may display a screen of walking on a hiking trail or climbing a mountain while the exercise is performed to provide the user with an experience similar to hiking.

[0061] For example, the computing device can provide an exercise load to the user through the handle portion (120) or foot portion (130) based on exercise course information generated to correspond to the terrain characteristics of the exercise course. Additionally, the computing device can control the step height of the handle portion (120) or foot portion (130) based on the exercise course information while the exercise course is in progress.

[0062] At this time, when the handle portion (120) and the foot portion (130) are raised or lowered by the user, the drive unit can provide power to the handle or stepper to move it. Through this, users with weak muscles or those requiring exercise assistance can prevent injuries caused by excessive exercise. For example, the drive unit can provide power to the handle or stepper to move the handle or stepper upward. Additionally, when the user performs the action of lowering the handle or stepper, the drive unit can provide power upward to the handle or stepper to control the lowering speed of the handle or stepper.

The sensors (220) may include an encoder and a force sensor. The sensors (220) may be placed on each handle and each stepper. Additionally, each handle and each stepper may include multiple sensors. For example, the stepper may include a sensor that senses a downward force and a sensor that senses an upward force.

[0076] Additionally, the sensor (220) may identify the position of each handle and each stepper. Specifically, the sensor (220) may identify the position of the handle and stepper moving on the guide. To this end, the sensor (220) may include an IMU sensor, an accelerometer, a laser sensor, etc.

[0077] The drive unit (230) may include one or more motors (hereinafter referred to as motors) for providing exercise load to a user and a controller for controlling the motors. Additionally, the drive unit (230) may include cables, wires, etc., connecting the motors to the handle unit (120) and the footrest unit (130). For example, a plurality of handles and a plurality of steppers may each be connected to the same motor via cables. Accordingly, when the motor of the drive unit (230) rotates, the cables of the handles and steppers connected to a specific guide may be extended, while the cables of the handles and steppers connected to the remaining guides may be shortened. Meanwhile, as the cables are extended, the direction of movement of the handles and steppers may differ. For example, when the cable connected to the handle extends, the handle may move upward, and when the cable connected to the stepper extends, the stepper may move downward. At this time, the handles and steppers connected to different guides may move in an alternating manner. Specifically, when a stepper connected to a specific guide moves downward, the stepper connected to the remaining guide can move upward. According to this connection method, a plurality of handles and a plurality of steppers connected to the drive unit (230) can move organically.

[0078] Meanwhile, the drive unit (230) can control movement by providing power to at least one of the multiple handles and multiple steppers while the multiple handles and multiple steppers are moved by the user. This will be explained in detail in FIG. 4.

[0079] The processor (211) can control the motor to provide a determined size or type of exercise load. For example, the processor (211) can provide various types of exercise loads, such as elastic resistance, viscous resistance, isometric and real-time weight change. The type or size of the exercise load can be determined based on at least one of information entered by the user, pre-set information, or a sensing value measured by the sensor (220).

[0080] Meanwhile, the drive unit (230) may include a motor connected to a plurality of steppers and a motor connected to a plurality of handles, respectively. For example, the drive unit (230) may include a first motor connected to a plurality of handles and a second motor connected to a plurality of steppers. However, it is not limited thereto, and the drive unit (230) may include a plurality of motors connected to each handle and each stepper. For example, the drive unit (230) may include a third and fourth motor connected to a plurality of handles, respectively, and a fifth and sixth motor connected to a plurality of steppers, respectively.

[0081] Hereinafter, for convenience of explanation of the present disclosure, a guide formed on the right side of the training device of FIG. 1 is referred to as the first guide, and a stepper and a handle connected to the first guide are referred to as the first stepper and the first handle. Additionally, a guide formed on the left side of the training device is referred to as the second guide, and a stepper and a handle connected to the second guide are referred to as the second stepper and the second handle.

[0082] FIG. 3 is a flowchart schematically illustrating a method of controlling a training device (100) according to a user's exercise start command according to one embodiment of the present disclosure. FIG. 4 is an example diagram illustrating a method of controlling a training device (100) according to a user's exercise start command according to one embodiment of the present disclosure.

[0083] Referring to FIG. 3, the processor (211) receives an exercise start command for the electric training device (100) (S310). Specifically, the processor (211) may receive an exercise start command from a user through the display (150) or the interface of the training device (100) (e.g., a key, a microphone, etc.). Here, the exercise start command may be a turn-on command or a wake-up command for the electric training device (100). Alternatively, the exercise start command may be a pre-set command requesting the start of exercise after setting the exercise mode and exercise intensity, etc. for the training device (100) in standby mode. At this time, when the processor (211) receives the exercise start command, it may switch the mode of the training device (100) to an exercise mode.

[0084] And, when a command to start exercise is received, the processor (211) identifies the positions of the first stepper (131) and the second stepper (132) and can adjust the positions of the first stepper (131) and the second stepper (132) (S320).

[0085] Specifically, the processor (211) can adjust the position of the stepper so that the user can safely board the training device (100). In particular, the processor (211) can automatically adjust the position of the stepper by controlling the drive unit (230) before the user places their feet on the stepper so that the user can comfortably place their feet on the stepper.

[0086] In particular, the processor (211) can control the drive unit (230) to adjust the position of the stepper set as the main stepper among the first stepper (131) and the second stepper (132) to the first position (p1), and to adjust the position of the remaining steppers other than the main stepper to the second position (p2) which is higher than the first position (p1).

[0087] Specifically, the processor (211) can identify the primary stepper among the first stepper (131) and the second stepper (132). Here, the primary stepper may be the stepper on which the user first places their feet to board the training device (100). Then, the processor (211) can adjust the position of the identified primary stepper to a first position (p1) and adjust the position of the remaining steppers other than the primary stepper to a second position (p2) higher than the first position (p1).

[0088] For example, referring to FIG. 4, when the first stepper (131) among the first stepper (131) and the second stepper (132) is identified as the main stepper, the processor (211) can control the drive unit (230) to move the first stepper (131) to a first position (p1) and move the second stepper (132) to a second position (p2) higher than the first position (p1). In particular, the processor (211) can rotate the motor (231) of the drive unit (230) to extend the cable (232) connected to the first stepper (131) to move the position of the first stepper (131) to the first position (p1), and shorten the cable (232) connected to the second stepper (132) to move the position of the second stepper (132) to the second position (p2). Meanwhile, by setting the position of the main stepper (i.e., the first position (p1)) to a lower position than the position of the remaining stepper (i.e., the second position (p2)), the user can conveniently and stably board the training device (100) as if climbing stairs.

[0089] Meanwhile, according to one embodiment of the present disclosure, the processor (211) may set the stepper located closer to the first position (p1) among the first stepper (131) and the second stepper (132) as the main stepper. That is, the processor (211) may set the stepper located closer to the first position (p1) among the first stepper (131) and the second stepper (132) as the main stepper to prevent waste of resources (e.g., power, etc.) of the training device (100) or to allow the user to quickly board the training device (100). Then, the processor (211) may move the stepper set as the main stepper to the first position (p1) and move the remaining stepper to the second position (p2).

[0090] Alternatively, according to one embodiment of the present disclosure, the processor (211) may set a primary stepper based on user information stored in memory (212). The user information may include information about the foot the user primarily uses, or information about the foot that the user is relatively stronger in. In particular, such user information may be obtained by sensing the force transmitted from the user's foot to the stepper while the user is exercising. Specifically, the processor (211) may obtain user information by sensing the user's force transmitted to each stepper while the user is exercising, thereby identifying the foot the user primarily uses or identifying the foot that is relatively stronger among the two feet. The user information may be matched with the user's identification information (e.g., user ID, name, etc.) and stored in memory (212). Based on the previously stored user information, the processor (211) may set a stepper corresponding to the foot the user primarily uses or the foot that is relatively stronger as the primary stepper.

[0091] Additionally, according to one embodiment of the present disclosure, the processor (211) may acquire user information and determine a first position (p1) and a second position (p2) based on the acquired user information. At this time, the user information may include the user's height and stride information.

[0092] Specifically, the processor (211) can determine the position and spacing of the first stepper (131) and the second stepper (132) based on at least one of the user's height or stride length. For example, if the user's height is short, the first position (p1) of the main stepper can be set lower, and if the user's stride length is short, the spacing between the first position (p1) and the second position (p2) can be set narrower. The processor (211) can receive information on the user's height and the user's stride length through the display (150) or the user interface.

[0093] Meanwhile, when the first stepper (131) and the second stepper (132) are connected to and controlled by the same motor (231) of the drive unit (230), the position of the second stepper (132) can also be determined as the position of the first stepper (131) is determined. That is, if the motor (231) rotates in the direction in which the cable (232) connected to the first stepper (131) extends, the cable (232) connected to the second stepper (132) can be shortened in the opposite direction. Therefore, when the position of the first stepper (131) is determined, the position of the second stepper (132) can be determined relatively. Accordingly, the processor (211) can simultaneously determine the first position (p1) for the main stepper and the second position (p2) for the remaining stepper by taking into account both the height and stride of the user.

[0094] FIG. 5 is an exemplary diagram illustrating a method for preventing crushing accidents caused by a moving stepper according to one embodiment of the present disclosure.

[0095] According to one embodiment of the present disclosure, the processor (211) can detect an external resistance force acting in a direction opposite to the direction of movement of the first stepper (131) and the second stepper (132) while adjusting the positions of the first stepper (131) and the second stepper (132). Then, when the external resistance force is detected, the processor (211) can control the drive unit (230) so that the stepper among the first stepper (131) and the second stepper (132) in which the external resistance force is detected stops.

[0096] Specifically, the processor (211) can detect an external resistance force acting on either the first stepper (131) or the second stepper (132) while adjusting the positions of the first stepper (131) and the second stepper (132) through the sensor (220). Here, the external resistance force may be a force acting in a direction opposite to the direction of movement of the first stepper (131) and the second stepper (132). The processor can detect whether an external resistance force is acting on the first stepper (131) and the second stepper (132) while the first stepper (131) and the second stepper (132) are moving through the sensor (220) provided on the first stepper (131) and the second stepper (132), respectively. And, when the external resistance force is detected, the processor (211) can control the drive unit (230) to stop the movement of the stepper where the external resistance force is detected. For example, the processor (211) can stop the rotation of the motor (231) of the drive unit (230) or rotate the motor (231) in the opposite direction to stop the movement of the stepper when an external resistance force is detected. Through this, the processor (211) can prevent an accident of an object (e.g., user's foot, pet, baby, etc.) located on the moving stepper during the process of moving the first stepper (131) and the second stepper (132). Such prevention of accidents of being crushed can be performed by setting a Safe Mode in the training device (100). The Safe Mode is a mode that prevents accidents of being crushed by the stepper during the process of the stepper being moved by the processor (211) or by the user during exercise, and can be set in parallel with the exercise mode.

[0097] In particular, according to one embodiment of the present disclosure, the processor (211) can detect an external resistance force acting upward through the lower surface of the stepper that moves downward among the first stepper (131) and the second stepper (132) while adjusting the positions of the first stepper (131) and the second stepper (132).

[0098] Specifically, while the processor (211) adjusts the positions of the first stepper (131) and the second stepper (132), it can detect an external resistance force acting upward on the moving stepper during the process of moving the stepper downward, where the first position (p1) and the second position (p2) are set at a relatively lower position relative to the initial positions of the first stepper (131) and the second stepper (132), respectively. At this time, the processor (211) can detect the external resistance force acting upward through a sensor (220) provided on the lower surface of the stepper moving downward. Referring to FIG. 5, the processor (211) controls the drive unit (230) to move the first stepper (131), which is set as the main stepper among the first stepper (131) and the second stepper (132), downward and the second stepper (132), which is set as the remaining stepper, upward. During this process, the processor (211) can detect an external resistance force acting upward through the lower surface of the first stepper (131) by the cat being crushed by the first stepper (131). At this time, as the external resistance force is detected, the processor (211) can control the drive unit (230) to stop the downward movement of the first stepper (131). By doing so, the processor (211) can prevent the cat from being crushed by the stepper.

[0099] Additionally, according to one embodiment of the present disclosure, if the magnitude of the detected external resistance force is greater than or equal to a preset value, the processor (211) can control the driving unit (230) so that the stepper with the detected external resistance force among the first stepper (131) and the second stepper (132) moves in the opposite direction.

[0100] Specifically, the processor (211) can determine whether the magnitude of the external resistance force acting upwardly detected for a stepper moving downwards is greater than or equal to a preset value. If the processor (211) identifies that the magnitude of the external resistance force acting upwards is greater than or equal to a preset value, it determines that the object lying beneath the stepper is a pet or a person, and can control the drive unit (230) so that the stepper moving downwards moves upwards in the opposite direction.

[0101] In particular, the processor (211) can identify the type of object pinned under the stepper based on the magnitude of the external resistance force. Specifically, the processor (211) can identify the type of object pinned under the stepper based on the magnitude of the external resistance force detected in the stepper moving downward from the point where the external resistance force decreases and the rate of increase in magnitude. At this time, the processor (211) can acquire object information (sound of the object, image of the object, etc.) using the speaker, camera, etc. of the training device (100), and can predict the type of object by considering the acquired object information together with the magnitude of the external resistance force (and the rate of increase in magnitude) detected in the stepper. At this time, if the processor (211) determines that the object is a pet or a person, it can move the stepper upward but increase the speed of movement to quickly prevent a pinning accident.

[0102] According to one embodiment of the present disclosure, when the processor (211) detects that the user's foot is placed on the first stepper (131) and the second stepper (132), respectively, the drive unit (230) can be controlled to adjust the position of the main stepper and the remaining stepper to a third position of the same height.

[0103] Specifically, the processor (211) can detect whether the user's feet are placed on the first stepper (131) and the second stepper (132). That is, the processor (211) can detect whether the user has boarded the training device (100). To do this, the processor (211) can determine whether the user's feet are placed on the first stepper (131) and the second stepper (132) by detecting whether a downward force is applied to both the first stepper (131) and the second stepper (132) through sensors (220) included in the first stepper (131) and the second stepper (132), respectively. Then, if the processor (211) determines that the user's feet are placed on the first stepper (131) and the second stepper (132), respectively, it determines that the user's exercise preparation is complete and can position the main stepper and the remaining stepper at the same height (i.e., the third position). Through this, the processor (211) can induce the user to start exercising.

[0104] FIG. 6 is a flowchart schematically illustrating a method of controlling a training device (100) during a user's exercise according to one embodiment of the present disclosure. FIG. 7 is an illustrative diagram illustrating a method of controlling a training device (100) during a user's exercise according to one embodiment of the present disclosure.

[0105] S610 and S620, illustrated in FIG. 6, correspond to S310 and S320, illustrated in FIG. 3, so a detailed description is omitted. Additionally, step S330 relates to an embodiment in which the positions of the main stepper and the remaining stepper are adjusted to the same position as the seating of the first stepper (131) and the second stepper (132) of the user's foot described above is detected, so a detailed description is omitted.

[0106] According to one embodiment of the present disclosure, when the user’s different feet are placed on the first stepper and the second stepper respectively and the first stepper and the second stepper are moved by the user, the processor can control the drive unit so that the first stepper and the second stepper move up and down in an alternating manner along the first guide (111) and the second guide (112) within a preset operating range (S640).

[0107] Specifically, the processor (211) can detect movement of the first stepper (131) and the second stepper (132) by the user. For example, the processor (211) can detect the first stepper (131) and the second stepper (132) moving according to the user's force when the exercise mode is set based on the user's exercise start command and the user places their feet on the first stepper (131) and the second stepper (132), respectively, in the exercise mode. The processor (211) can control the drive unit (230) to cause the first stepper (131) and the second stepper (132) to move back and forth up and down in an alternating manner. Referring to FIG. 7, the processor (211) can control the drive unit (230) so that when the first stepper (131) is lowered, the second stepper (132) is raised, and when the first stepper (131) is raised, the second stepper (132) is lowered. When the first stepper (131) and the second stepper (132) are connected to the motor (231) of the drive unit (230) through a cable (232), if a user applies force to the first stepper (131) to lower the first stepper (131), the second stepper (132) connected to the motor (231) can be raised.

[0108] Additionally, the processor (211) can control the drive unit (230) so that when the first handle (121) and the second handle (122) are moved by the user, the first handle (121) and the second handle (122) move back and forth up and down along the first guide (111) and the second guide (112) in an intersecting manner within a preset operating range. At this time, the processor (211) can control the drive unit (230) so that the first handle (121) and the second handle (122) also move in response to the movement of the first stepper (131) and the second stepper (132). Specifically, the processor (211) can control the drive unit (230) so that when the first stepper (131) and the second stepper (132) intersect and move up and down, the first handle (121) moves down and the second handle (122) moves up.

[0109] Meanwhile, the processor (211) can control the drive unit (230) so that the first stepper (131) and the second stepper (132) move back and forth up and down in an intersecting manner within a preset operating range. Here, the preset operating range may be a range in which the first stepper (131) and the second stepper (132) can move on the first guide (111) and the second guide (112), respectively. Referring to FIG. 7, the processor (211) can set the operating range of the first stepper (131) to L1 on the first guide (111) and the operating range of the second stepper (132) to L2 on the second guide (112). At this time, the first stepper (131) can move within a range L1 on the first guide (111), and the second stepper (132) can move within a range L2 on the second guide (112), and this can be controlled by a processor (211) based on the drive unit (230). Meanwhile, L1 and L2 may be the same range.

[0110] In addition, referring to FIG. 7, the processor (211) can set the operating range of the first handle (121) to L3 on the first guide (111) and the operating range of the second handle (122) to L4 on the second guide (112). At this time, the first handle (121) can move within the L3 range on the first guide (111), and the second handle (122) can move within the L4 range on the second guide (112), and this can be controlled by the processor (211) based on the drive unit (230). Meanwhile, L3 and L4 may be the same range.

[0111] The processor (211) can set the range of motion (L1 and L2) of the steppers (first and second steppers (131 and 132)) respectively based on the user's body information. In particular, the processor (211) can set the range of motion based on the user's height and the user's stride. Specifically, the processor (211) can set the range of motion of the first stepper (131) and the second stepper (132) respectively based on at least one of the user's height and the user's stride. For example, the greater the user's height or the wider the stride, the wider the range of motion of the first stepper (131) and the second stepper (132) may be formed. Meanwhile, the first and second steppers (131 and 132) may be set differently based on the length of both legs.

[0112] Additionally, the processor (211) may set the operating range of the first and second handles (121 and 122) in correspondence with the operating range set in the first and second steppers (131 and 132). Furthermore, the processor (211) may set the operating range of the first handle (121) and the second handle (122), respectively, based on at least one of the user's key and the user's wingspan.

[0113] The processor (211) can detect the positions of the first stepper (131) and the second stepper (132) while the first stepper (131) and the second stepper (132) are moving back and forth in an alternating manner. The processor (211) can detect the positions of the first stepper (131) and the second stepper (132) in real time through the sensor unit (220). The positions of the first stepper (131) and the second stepper (132) may be the heights of the first stepper (131) and the second stepper (132) relative to the floor surface, or the respective positions of the first stepper (131) and the second stepper (132) on the first guide (111) and the second guide (112). The processor (211) can identify the position of the first stepper (131) and the position of the second stepper (132) respectively, based on the sensing values ​​obtained through the sensor (220) included in the first stepper (131) and the sensor (220) included in the second stepper (132).

[0114] After setting the operating range, the processor (211) can set the critical points of the first stepper (131) and the second stepper (132) on the first guide (111) and the second guide (112), respectively. The critical points may be points where the movement of the first stepper (131) and the second stepper (132) is restricted. That is, when the first stepper (131) and the second stepper (132) are located at the critical points, the first stepper (131) and the second stepper (132) may be stopped.

[0115] According to one embodiment of the present disclosure, the processor (211) may set the highest point and the lowest point of the operating range as critical points. The processor (211) may control the drive unit (230) so that when the position of either the first stepper (131) or the second stepper (132) reaches the critical point, either stepper is stopped. That is, the processor (211) may control the drive unit (230) so that the first stepper (131) and the second stepper (132) do not move outside the operating range set for each. To this end, the processor (211) may control the drive unit (230) so that when each stepper (i.e., the first stepper and the second stepper (131 and 132)) is identified as having reached the critical point of the operating range, each stepper (131 and 132) is stopped. And, the processor (211) can control the drive unit (230) so that the stepper moves in a direction opposite to the direction of movement of the stepper that has reached a critical point. For example, referring to FIG. 7, when the first stepper (131) moving downward reaches the lowest point of the L1 range on the first guide (111), the processor (211) can control the drive unit (230) to apply an upward resistance force to the first stepper (131) to stop the first stepper (131). Then, the processor (211) can control the drive unit (230) to move the first stepper (131) upward again. Here, the resistance force may be a force acting in a direction opposite to the direction of movement of the stepper moved by the drive unit (230).

[0116] Meanwhile, the processor (211) can control the drive unit (230) to stop the first stepper (131) and the second stepper (132) if, based on the magnitude of the detected force, it is determined that the user's foot has slipped out of at least one of the first stepper (131) and the second stepper (132) while the first stepper (131) and the second stepper (132) are moving back and forth up and down in an alternating manner along the first guide (111) and the second guide (112).

[0117] The processor (211) can continuously detect the force transmitted from the user to the first stepper (131) and the second stepper (132) through the sensor (220) included in the first stepper (131) and the second stepper (132) while the user is exercising. At this time, the processor (211) can detect whether the user's foot, which is seated on at least one of the first stepper (131) and the second stepper (132), has come off the stepper based on the magnitude of the force detected through the sensor (220). For example, while the stepper is moving in a certain direction, the processor (211) can determine that the user's foot has come off the stepper if the force of the user, which was continuously detected, is suddenly not detected, or if the magnitude of the detected force of the user is less than a preset value. At this time, if the processor (211) determines that the user's foot has left at least one of the first stepper (131) and the second stepper (132), it can control the drive unit (230) to stop the movement of the first stepper (131) and the second stepper (132). By doing so, the processor (211) can prevent injury by preventing the user, who has fallen off the training device (100) during exercise, from colliding with the moving stepper.

[0118] Meanwhile, even while the user is exercising, the processor (211) may detect an external resistance force acting on either the first stepper (131) or the second stepper (132) and stop the movement of the first stepper (131) and the second stepper (132). That is, according to the safe mode, the processor (211) can prevent a crushing accident caused by the stepper.

[0119] Referring again to FIG. 6, according to one embodiment of the present disclosure, the processor (211) detects a force transmitted from a user to a first stepper (131) and a second stepper (132), determines a primary stepper among the first stepper (131) and the second stepper (132) based on the magnitude of the detected force, and can store the determined primary stepper information by matching it with user information (S650).

[0120] The processor (211) detects the force transmitted to the first stepper (131) and the second stepper (132) to identify the dominant foot (i.e., the foot primarily used) among the user's two feet, and can determine the stepper corresponding to the identified dominant foot as the main stepper. Then, the processor (211) can store the information of the determined main stepper in memory (212) by matching it with the user's identification information (e.g., user ID, user name, etc.). Through this, when the user starts exercising thereafter, the processor (211) can adjust the position of the stepper based on the information of the main stepper stored by matching it with the user's identification information.

[0121] According to one embodiment of the present disclosure, when the processor (211) receives a command to end exercise for the electric training device (100) while the first stepper (131) and the second stepper (132) are moving up and down in a reciprocating manner along the first guide (111) and the second guide (112), the processor (211) can identify the positions of the first stepper (131) and the second stepper (132) and adjust the positions of the first stepper (131) and the second stepper (132). In particular, the processor (211) can control the drive unit (230) to adjust the position of the stepper set as the main stepper among the first stepper (131) and the second stepper (132) to a fourth position, and to adjust the position of the remaining steppers other than the main stepper to a fifth position higher than the fourth position.

[0122] Specifically, the processor (211) may receive an exercise termination command from a user who is exercising. Here, the exercise termination command may be a turn-off command for the training device (100) or a command requesting the termination of control of the drive unit (230) for the first stepper (131) and the second stepper (132). The processor (211) may receive the exercise termination command through the display (150) or the interface of the training device (100).

[0123] Additionally, the processor (211) can adjust the positions of the first stepper (131) and the second stepper (132) so that the user can safely disembark from the training device (100). Specifically, the processor (211) can identify the main stepper among the first stepper (131) and the second stepper (132). Since the above description applies equally to this, a detailed description is omitted. Furthermore, the processor (211) can control the drive unit (230) to move the main stepper to a fourth position and move the remaining stepper to a fifth position higher than the fourth position. Here, the fourth position and the fifth position may be the same as the first position (p1) and the second position (p2) described above.

[0126] The camera (850) captures objects around the user and the training device (100) to obtain images of the objects. Specifically, based on the images of the user obtained by the camera (850), the processor (811) can determine whether the user is boarding the training device (100). Additionally, the camera (850) can obtain images of the lower area of ​​the steppers (131 and 132) to determine whether an object is located at the bottom of the steppers (131 and 132). To this end, the camera (850) may be implemented with an image sensor such as a CMOS Image Sensor (CIS) having a CMOS structure or a Charge Coupled Device having a CCD structure. However, it is not limited thereto, and the camera (850) may be implemented with a camera module of various resolutions capable of capturing a subject. Meanwhile, the camera (850) can be implemented as a depth camera (e.g., IR depth camera, etc.), a stereo camera, or an RGB camera, etc.

[0127] The speaker (860) is configured to output various audio data that has undergone various processing operations, such as decoding, amplification, and noise filtering, by an audio processing unit (not shown). The speaker (860) can output various notification sounds or voice messages. According to one embodiment of the present disclosure, when the processor (310) identifies that an object is placed under the stepper (131 and 132), it can output a warning sound or a warning voice message through the speaker (860).

[0128] The microphone (870) can receive user voice corresponding to the user's speech, and the received user voice may correspond to a control command (e.g., an exercise start command or an exercise end command) for controlling the operation of the training device (100). The microphone (870) acquires vibrations corresponding to the user voice and converts the acquired vibrations into electrical signals. To this end, the microphone may include an A / D converter (Analog to Digital Converter) and may operate in conjunction with an A / D converter located outside the microphone. Meanwhile, at least some of the user voice received through the microphone (870) may be input into a speech recognition and natural language understanding model.

[0129] The user interface (880) is a configuration used for the electric training device (100) to perform interaction with the user (1), and may include at least one of a touch sensor, a motion sensor, a button, a jog dial, and a switch, but is not limited thereto. The processor (811) may receive user identification information (ID, name, gender, etc.) or receive an exercise start command or an exercise end command through the user interface (880).

[0130] Meanwhile, according to one embodiment of the present disclosure, a non-transitory computer-readable medium may be provided that stores a program for sequentially performing the control method of the electric training device (100) described above.

[0131] A non-transient readable medium refers to a medium that stores data semi-permanently and can be read by a device, rather than a medium that stores data for a short moment, such as a register, cache, or memory. Specifically, the various applications or programs described above may be stored and provided on non-transient readable media such as CDs, DVDs, hard disks, Blu-ray discs, USBs, memory cards, and ROMs.

[0132] The various embodiments of the present disclosure described above may be combined with additional embodiments and modified to the extent understandable to those skilled in the art in light of the detailed description above. The embodiments of the present disclosure are illustrative in all respects and should be understood as not restrictive.
