[0027]

[0028] FIG. 1A is a drawing for explaining an overview of a wearable device worn on a user's body according to one embodiment.

[0029] Referring to FIG. 1A, a wearable device (120) may be a device worn on a user's body to assist the user's walking, exercise, and / or work. In an embodiment, the term "wearable device" may be replaced with a wearable robot, a walking assistance device, an exercise assistance device, etc. The user may be a human or an animal, but is not limited thereto. The wearable device (120) may be worn on the user's body (e.g., lower body (legs, ankles, knees, etc.), upper body (torso, arms, wrists, etc.), or waist) to provide an external force (e.g., assistance force and / or resistance force) to the user's body movement. Assistance force (or assistance torque) refers to a force applied in the same direction as the direction of the user's body movement, and resistance force (or resistance torque) refers to a force applied in the opposite direction to the direction of the user's body movement.

[0030] When the wearable device (120) performs a walking assistance function to assist the user's walking, the wearable device (120) can assist the user's walking by providing assistive force (assistive torque) to the user's body to assist part or all of the user's legs. The wearable device (120) can assist the force required for the user's walking, thereby enabling independent walking or long-term walking, thereby expanding the user's walking ability. The wearable device (120) can also help improve the walking of a pedestrian with abnormal walking habits or walking posture.

[0031] When the wearable device (120) performs an exercise function to enhance the user's exercise effect, the wearable device (120) may impede the user's body movement or provide resistance to the user's body movement by providing resistance (or resistance torque) to the user's body. When the wearable device (120) is, for example, a hip-type wearable device, the wearable device (120) may provide resistance to the user's body movement while being worn on the leg, thereby further enhancing the user's exercise effect. The user may perform a walking motion while wearing the wearable device (120) for exercise, and in this case, the wearable device (120) may provide resistance to the leg movement during the user's walking motion.

[0032] In the embodiment, for the convenience of explanation, a hip-type wearable device (120) worn on the waist and legs is described as an example. However, as described above, the wearable device (120) may be worn on other body parts (e.g., upper arms, lower arms, hands, calves, feet) other than the waist and legs (particularly thighs), and the shape and configuration of the wearable device (120) may vary depending on the body part on which it is worn.

When the smart watch (132) is connected to the electronic device (110) via a wireless communication link, and the electronic device (110) is connected to the wearable device (120) via a wireless communication link, the smart watch (132) can control the wearable device (120) via the electronic device (110). Without being limited thereto, the smart watch (132) can be directly connected to the wearable device (120) and control the wearable device (120).

[0039] In one embodiment, the wearable device (120) can receive the user's heart rate information from the smart watch (132).

[0040] In one embodiment, the electronic device (110) may transmit a control signal to another wearable device (130) that commands the other wearable device (130) to provide feedback corresponding to the state of the wearable device (120) to the user. The other wearable device (130) may, upon receiving the control signal, provide (or output) feedback (e.g., at least one of visual feedback, auditory feedback, or tactile feedback) corresponding to the state of the wearable device (120).

[0041] In one embodiment, the electronic device (110) may communicate with the server (140) using short-range wireless communication (e.g., Wi-Fi) or mobile communication (e.g., 4G, 5G, etc.).

[0042] In one embodiment, the electronic device (110) may receive user information (e.g., profile information) from the user. The profile information may include, for example, at least one of age, gender, height, weight, or BMI (Body Mass Index), or a combination thereof. The electronic device (110) may transmit the user's profile information to the server (140) and / or the wearable device (120).

The drive module (30) can output a torque corresponding to the torque value.

[0080] According to one embodiment, each of the motor driver circuits (370, 370-1) can control each of the motors (380, 380-1) under the control of the processor (310), and by such control, each of the motors (380, 380-1) can generate torque (e.g., resistive torque and / or auxiliary torque).

[0081] According to one embodiment, the communication module (390) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the wearable device (300, 300-1) and an external electronic device (e.g., the electronic device (110) of FIG. 1B or another wearable device (130) of FIG. 1B), and the performance of communication through the established communication channel. The communication module (390) may include a communication circuit (e.g., a Bluetooth communication circuit, etc.).

[0082] According to one embodiment, the wearable device (300, 300-1) may include a display module. The display module may include, for example, a display and / or a lighting unit (e.g., the lighting unit (60) of FIG. 2A). The processor (310) may control the display module so that the display module can provide visual feedback to the user.

[0083] According to one embodiment, the wearable device (300, 300-1) may include an audio output module. The audio output module may include, for example, one or more speakers. The processor (310) may control the audio output module so that the audio output module can provide auditory feedback to the user.

[0086]

[0087] FIG. 4 is a diagram illustrating interaction between a wearable device and an electronic device according to one embodiment.

[0088] Referring to FIG. 4, the wearable device (120) can communicate with an electronic device (410) (e.g., the electronic device (110) of FIG. 1B or another wearable device (130) of FIG. 1B). For example, the electronic device (410) can be a user terminal of a user using the wearable device (120) or a dedicated controller device for the wearable device (120). According to one embodiment, the wearable device (100) and the electronic device (410) can be connected to each other via short-range wireless communication (e.g., Bluetooth communication, Wi-Fi communication).

[0089] According to one embodiment, the electronic device (410) may execute an application for checking the status of the wearable device (120) or controlling or operating the wearable device (120). By executing the application, a screen of a user interface (UI) for controlling the operation of the wearable device (120) or determining the operation mode of the wearable device (120) may be displayed on the display (412) of the electronic device (410). The UI may be, for example, a graphical user interface (GUI).

[0090] According to one embodiment, a user may input a command to control the operation of the wearable device (120) (e.g., a command to instruct to operate in an assistive mode that generates assistive force or a command to instruct to operate in a resistive mode that generates resistive force) or change the settings of the wearable device (120) through a GUI screen on the display (212) of the electronic device (410). The electronic device (410) may generate a control command (or a control signal) corresponding to the operation control command or setting change command input by the user, and transmit the generated control command to the wearable device (120).

The electronic device (410) can provide the user with result information (e.g., walking ability information, exercise ability information, exercise movement evaluation information) derived by analyzing the control result and / or sensor data through a GUI screen.

[0091]

[0092] FIG. 5 is a diagram illustrating an example of an exercise program provided by a wearable device according to one embodiment.

[0093] Referring to FIG. 5, an exercise program (500) according to an embodiment may include one or more resistance intervals (511, 521) and one or more assist intervals (512, 522). Each of the resistance intervals (511, 521) may represent a time interval during which, for example, a wearable device (120) (e.g., the wearable device (120) of FIGS. 1A and 1B, the wearable device (200) of FIG. 2, the wearable device (300) of FIG. 3A, and the wearable device (300-1) of FIG. 3B) provides a resistance torque (or resistance force) to the user, and each of the assist intervals (512, 522) may represent a time interval during which, for example, the wearable device (120) provides an assist torque (or assist force) to the user.

[0094] According to one embodiment, the exercise program (500) may include a first exercise program (e.g., an interval walking exercise program) and / or a second exercise program (e.g., a power walking exercise program).

[0095] According to one embodiment, the first exercise program may represent an exercise program in which a strong resistance force is provided to the user in the resistance zone (511, 521) and a weak assistance force is provided to the user in the assistance zone (512, 522). The resistance zone (511, 521) in the first exercise program may represent an exercise zone in which Zone 4, which will be described later, is a target heart rate range, and the assistance zone (512, 522) in the first exercise program may represent an exercise zone in which Zone 2, which will be described later, is a target heart rate range. The first exercise program may correspond to, for example, an exercise program for moderate intensity aerobic exercise.

[0096] According to one embodiment, the second exercise program may represent an exercise program in which a high intensity resistance is provided to the user in the resistance zones (511, 521) and a high intensity assistance is provided to the user in the assistance zones (512, 522). The resistance zones (511, 521) in the second exercise program may represent an exercise zone in which Zone 4, which will be described later, is a target heart rate range, and the assistance zones (512, 522) in the second exercise program may represent an exercise zone in which Zone 4 (or Zone 3), which will be described later, is a target heart rate range. The second exercise program may correspond to, for example, an exercise program for high intensity aerobic exercise.

[0097] According to one embodiment, a first set (510) of an exercise program (500) may include a resistance section (511) and an assist section (512), and a second set (520) may include a resistance section (521) and an assist section (522).

[0098] According to one embodiment, the wearable device (120) may adjust the exercise intensity of the resistance section (511) of the first set (510) (hereinafter referred to as the “first resistance section”) to determine the exercise intensity of the resistance section (521) of the second set (520) (hereinafter referred to as the “second resistance section”). The exercise intensity of each of the resistance sections (511, 521) may include, for example, at least one of a resistance intensity level related to the magnitude of the resistance torque, a target speed, or a target time.

[0099] According to one embodiment, the wearable device (120) can determine the exercise intensity of the assistance section (512) (hereinafter referred to as “first assistance section”) based on the exercise intensity of the first resistance section (511). The wearable device (120) can determine the exercise intensity of the assistance section (522) (hereinafter referred to as “second assistance section”) based on the exercise intensity of the second resistance section (521). The exercise intensity of each of the assistance sections (512, 522) may include, for example, at least one of an assistance intensity level related to the strength of the assistance torque, a target speed, or a target time. The wearable device (120) can determine the exercise intensity of the second assistance section (522) by adjusting the exercise intensity of the first assistance section (512).

[0100] According to one embodiment, the wearable device (120) can calculate the user's walking speed in each of the sections (511, 512, 521, 522). For example, the wearable device (120) can calculate the user's walking speed in each of the sections (511, 512, 521, 522) based on the acceleration value of the IMU (360) in each of the sections (511, 512, 521, 522) (e.g., the acceleration value in the frontal direction of the wearable device (120). Depending on the implementation, the wearable device (120) may not use the acceleration values ​​during the first time interval (e.g., the first minute) of each of the intervals (511, 512, 521, 522) and the acceleration values ​​during the second time interval (e.g., the last 15 seconds) of each of the intervals (511, 512, 521, 522) when calculating the walking speed.

[0101] According to one embodiment, a first resistance section (511) may have a resistance intensity level (e.g., 3) related to a resistance torque intensity (hereinafter, referred to as a “first resistance intensity level”), a target speed (e.g., 6 km / h) (hereinafter, referred to as a “first target speed”), and a target time (e.g., 4 minutes and 30 seconds) (hereinafter, referred to as a “first target time”) set (or determined) by the wearable device (120). The first target time may correspond to, for example, the length (e.g., time length) of the first resistance section (511).

[0102] According to one embodiment, the wearable device (120) can support multiple resistance intensity levels (e.g., 1 to 5). The higher the resistance intensity level, the greater the resistance torque the wearable device (120) can provide to the user. The higher the resistance intensity level, the greater the maximum resistance torque.

[0103] According to one embodiment, the wearable device (120) may provide the user with a resistance torque corresponding to a first resistance intensity level in the first resistance section (511).

[0104] According to one embodiment, the wearable device (120) may determine a target speed (e.g., 4.8 km / h) of the first assist section (512) based on the first target speed of the first resistance section (511). The first assist section (512) may be a next section (or a next exercise section) of the first resistance section (511). For example, the wearable device (120) may determine the target speed (e.g., 4.8 km / h of FIG. 5) of the first assist section (512) by multiplying the first target speed of the first resistance section (511) by a ratio (e.g., 0.8 or 1.05). The above-described ratio may be based on, for example, an exercise program (500) (e.g., the first exercise program or the second exercise program). For example, the first exercise program may be performed. In this case, the wearable device (120) can determine the target speed (e.g., 4.8 km / h) of the first auxiliary section (512) by multiplying the first target speed by a first ratio (e.g., 0.8). As another example, a second exercise program can be performed. In this case, the wearable device (120) can determine the target speed (e.g., 6.3 km / h) of the first auxiliary section (512) by multiplying the first target speed by a second ratio (e.g., 1.05).

[0105] According to one embodiment, the wearable device (120) may determine the assistance intensity level of the first assistance section (512) based on the target speed of the first assistance section (512). For example, the wearable device (120) may obtain an assistance intensity level (e.g., 2) corresponding to the target speed of the first assistance section (512) from a table (e.g., table (610) of FIG. 6 described below) in which assistance intensity levels correspond to target speeds, and may determine the obtained assistance intensity level (e.g., 2) as the assistance intensity level (e.g., 2) of the first assistance section (512).

[0106] According to one embodiment, the wearable device (120) can support multiple assist intensity levels (1 to 5). The higher the assist intensity level, the more intense the wearable device (120) can provide the user with assist torque. The higher the assist intensity level, the greater the maximum intensity of the assist torque.

[0107] According to one embodiment, the wearable device (120) may provide the user with an assist torque corresponding to an assist intensity level of the first assist section (512) in the first assist section (512).

[0108] According to one embodiment, the wearable device (120) may adjust the exercise intensity (e.g., at least one of a resistance intensity level, a target speed, or a target time) of the second resistance section (521) when the user's movement information (e.g., a walking speed) of the first resistance section (511) is outside the target speed range of the first resistance section (511). The adjustment of the exercise intensity may include, for example, at least one of adjustment of the resistance intensity level of the second resistance section (521), adjustment of the target speed of the second resistance section (521), or adjustment of the target time of the second resistance section (521).

[0109] According to one embodiment, the wearable device (120) may determine the target time (e.g., 3 minutes) of the first auxiliary section (512) based on the first target time of the first resistance section (511). The time of the first set (510) may be, for example, 7 minutes and 30 seconds. The wearable device (120) may determine the target time (e.g., 3 minutes) of the first auxiliary section (512) by subtracting the first target time (e.g., 4 minutes and 30 seconds) from the time of the first set (510) (e.g., 7 minutes and 30 seconds).

[0110] According to one embodiment, if the wearable device (120) determines that the user's movement (e.g., walking) in the first resistance section (511) is slow, the wearable device (120) may lower the exercise intensity (e.g., at least one of the resistance intensity level, the target speed, or the target time) of the next resistance section (e.g., the second resistance section (521)) of the first resistance section (511). If the wearable device (120) determines that the user's movement (e.g., walking) in the first resistance section (511) is fast, the wearable device (120) may increase the exercise intensity (e.g., at least one of the resistance intensity level, the target speed, or the target time) of the second resistance section (521).

[0111] According to one embodiment, the wearable device (120) can determine whether the user's walking speed in the first resistance section (511) (hereinafter referred to as "first walking speed") is outside the target speed range (e.g., target speed (e.g., 6 km / h) ± 0.5 km / h) (hereinafter referred to as "first target speed range") of the first resistance section (511). If the first walking speed is outside the first target speed range, the wearable device (120) can perform at least one of an operation of adjusting the first resistance intensity level to determine the resistance intensity level of the second resistance section (521), an operation of adjusting the first target speed to determine the target speed of the second resistance section (521), or an operation of adjusting the first target time to determine the target time of the second resistance section (521).

[0112] For example, the wearable device (120) may calculate the first walking speed of the wearable device (120) based on the acceleration value (e.g., the acceleration value in the front direction) of the IMU (360) in the first resistance section (511). Depending on the implementation, the wearable device (120) may not use the acceleration value during the first time section (e.g., the first 1 minute of the first resistance section (511)) of the first resistance section (511) and the acceleration value during the second time section (e.g., the last 15 seconds of the first resistance section (511)) when calculating the first walking speed.

[0113] When the wearable device (120) determines that the first walking speed exceeds the first target speed range (e.g., 5.5 km / h to 6.5 km / h) (e.g., when the user's movement in the first resistance section (511) is determined to be fast), the wearable device (120) may perform at least one of: an operation of determining the resistance intensity level of the second resistance section (521) as a second resistance intensity level higher than the first resistance intensity level; an operation of determining the target speed of the second resistance section (521) as a second target speed higher than the first target speed; or an operation of determining the target time of the second resistance section (521) as a second target time longer than the first target time. When the wearable device (120) determines that the first walking speed is less than the first target speed range (e.g., when it determines that the user's movement in the first resistance section (511) is slow), the wearable device (120) may perform at least one of: an operation of determining the resistance intensity level of the second resistance section (521) as a third resistance intensity level lower than the first resistance intensity level; an operation of determining the target speed of the second resistance section (521) as a third target speed lower than the first target speed; or an operation of determining the target time of the second resistance section (521) as a third target time shorter than the first target time.

[0114] According to one embodiment, the wearable device (120) may provide the user with a resistance torque corresponding to a resistance intensity level (A1 in FIG. 5) (e.g., a second resistance intensity level or a third resistance intensity level) of the second resistance section (521) in the second resistance section (521).

[0115] According to one embodiment, the wearable device (120) may determine a target speed (e.g., B2 in FIG. 5) of the second auxiliary section (522) based on a second target speed (A2 in FIG. 5) of the second resistance section (521). For example, the wearable device (120) may determine the target speed of the second auxiliary section (522) by multiplying the second target speed by a ratio (e.g., 0.8 or 1.05).

[0116] According to one embodiment, the wearable device (120) may determine the assistance intensity level (B1 of FIG. 5) of the assistance section (522) based on the target speed of the second assistance section (522). The wearable device (120) may adjust the assistance intensity level of the second assistance section (522) when the walking speed of the user in a previous assistance section (e.g., the first assistance section (512)) of the second assistance section (522) is outside the target speed range of the previous assistance section (e.g., the target speed of the first assistance section (512) ±0.5).

[0117] According to one embodiment, the wearable device (120) may determine the target time (e.g., B3 of FIG. 5) of the second auxiliary section (522) based on the target time (e.g., A3 of FIG. 5) of the second resistance section (521). The wearable device (120) may determine the target time (e.g., B3 of FIG. 5) of the second auxiliary section (522) such that the sum of the target time (e.g., A3 of FIG. 5) of the second resistance section (521) and the target time (e.g., B3 of FIG. 5) of the second auxiliary section (522) becomes a predetermined time (e.g., 7 minutes and 30 seconds).

[0118] According to one embodiment, the wearable device (120) may perform coaching (e.g., voice coaching) or provide guidance (e.g., voice guidance) to a user performing an exercise program (500) (e.g., a first exercise program or a second exercise program). “Coaching (or guidance)” may, for example, refer to an action of the wearable device (120) providing assistance (e.g., visual assistance and / or auditory assistance) to the user so that the user’s exercise can reach a goal.

[0119] For example, a user may perform a first exercise program. Table 1 below shows examples of sentences that the wearable device (120) provides to the user verbally in each section of the first exercise program (e.g., sections (511, 512, 521, 522) of FIG. 5).

[0120]

[0121] For another example, a user may perform a second exercise program. Table 2 below shows examples of sentences that the wearable device (120) provides audibly to the user in each section of the second exercise program (e.g., sections (511, 512, 521, 522) of FIG. 5).

[0122]

[0123] According to one embodiment, the wearable device (120) can perform wireless communication (e.g., Bluetooth communication) with an external electronic device (e.g., a smartwatch (132)). The external electronic device can obtain the user's heart rate information and transmit the heart rate information to the wearable device (120). The wearable device (120) can determine whether the user's heart rate information in each of the sections (511, 512, 521, 522) of the exercise program (500) falls within the target heart rate range of each of the sections (511, 512, 521, 522). In the case of the first exercise program, the target heart rate range of each of the resistance sections (511, 521) may be Zone 4, and the target heart rate range of each of the assistance sections (512, 522) may be Zone 2. For the second exercise program, the target heart rate range of each of the resistance zones (511, 521) may be Zone 4, and the target heart rate range of each of the assistance zones (512, 522) may be Zone 4 (or Zone 3).

[0124] According to one embodiment, the wearable device (120) can calculate the time for which the user's heart rate information is within the target heart rate range (or the time for which the heart rate information is maintained within the target heart rate range), and if the calculated time is greater than a certain time, it can be determined that the user has performed exercise while maintaining the target heart rate range.

[0125] In one embodiment, the heart rate ranges may be divided into, for example, Zone 1 to Zone 5. Zone 1 may represent, for example, a heart rate range corresponding to 50% to 60% of the user's maximum heart rate, Zone 2 may represent, for example, a heart rate range corresponding to 60% to 70% of the user's maximum heart rate, Zone 3 may represent, for example, a heart rate range corresponding to 70% to 80% of the user's maximum heart rate, Zone 4 may represent, for example, a heart rate range corresponding to 80% to 90% of the user's maximum heart rate, and Zone 5 may represent, for example, a heart rate range corresponding to more than 90% of the user's maximum heart rate.

[0126] Table 3 below shows an example of a comparison between Exercise Program 1 and Exercise Program 2.

[0127]

[0128] According to one embodiment, the assist intensity levels that the wearable device (120) can support may be, for example, 1 to 5. For the first exercise program, the maximum assist intensity level may be, for example, 3, and for the second exercise program, the maximum assist intensity level may be, for example, 5.

[0129]

[0130] FIGS. 6 and 7 are diagrams illustrating examples of a wearable device adjusting at least one of an intensity level, a target speed, or a target time according to one embodiment.

[0131] Referring to FIG. 6, a wearable device (120) according to an embodiment may adjust an exercise intensity based on whether a walking speed in a previous section (e.g., a previous resistance section or a previous assistance section) is outside a target speed range and the user's heart rate information (or average heart rate information) when the user performs an exercise program (500) (e.g., a first exercise program or a second exercise program). The exercise intensity may include, for example, at least one of an intensity level (e.g., a resistance intensity level and / or an assistance intensity level), a target speed, or a target time.

[0132] According to one embodiment, the user's heart rate information (or average heart rate information) in the first resistance zone (511) may belong to Zone 1 (or Zone 2 or Zone 3), and the first walking speed in the first resistance zone (511) may exceed the first target speed range or belong to the first target speed range. In this case, the wearable device (120) may perform at least one of an operation of determining a resistance intensity level (e.g., first resistance intensity level +1) of a second resistance section (521) by applying a first level value (e.g., +1) to a first resistance intensity level of a first resistance section (511), an operation of determining a target speed (e.g., first target speed +0.5) of a second resistance section (521) by applying a first speed value (e.g., +0.5) to a first target speed of the first resistance section (511), or an operation of determining a target time (e.g., first target speed +30) of a second resistance section (521) by applying a first time value (e.g., +30 seconds) to a first target time of the first resistance section (511).

[0133] According to one embodiment, the user's heart rate information (or average heart rate information) in the first resistance zone (511) may belong to Zone 1 (or Zone 2 or Zone 3) and the first walking speed in the first resistance zone (511) may be less than the first target speed range. In this case, the wearable device (120) may perform at least one of an operation of determining a resistance intensity level (e.g., first resistance intensity level -1) of a second resistance section (521) by applying a second level value (e.g., -1) to a first resistance intensity level of a first resistance section (511), an operation of determining a target speed (e.g., first target speed -0.5) of a second resistance section (521) by applying a second speed value (e.g., -0.5) to a first target speed of the first resistance section (511), or an operation of determining a target time (e.g., first target time -30) of a second resistance section (521) by applying a second time value (e.g., -30 seconds) to a first target time of the first resistance section (511).

[0134] According to one embodiment, the user's heart rate information (or average heart rate information) in the first resistance zone (511) may belong to Zone 4, and the first walking speed in the first resistance zone (511) may exceed the first target speed range. In this case, the wearable device (120) may perform at least one of an operation of determining a resistance intensity level (e.g., first resistance intensity level +1) of a second resistance section (521) by applying a first level value (e.g., +1) to a first resistance intensity level of a first resistance section (511), an operation of determining a target speed (e.g., first target speed +0.5) of a second resistance section (521) by applying a first speed value (e.g., +0.5) to a first target speed of the first resistance section (511), or an operation of determining a target time (e.g., first target speed +30) of a second resistance section (521) by applying a first time value (e.g., +30 seconds) to a first target time of the first resistance section (511).

[0135] According to one embodiment, the user's heart rate information (or average heart rate information) in the first resistance zone (511) may belong to Zone 4, and the first walking speed in the first resistance zone (511) may be within the first target speed range. In this case, the wearable device (120) may determine the first resistance intensity level, the first target speed, and the first target time of the first resistance zone (511) as the resistance intensity level, the target speed, and the target time of the second resistance zone (521), respectively.

[0136] According to one embodiment, the user's heart rate information (or average heart rate information) in the first resistance zone (511) may belong to Zone 4, and the first walking speed in the first resistance zone (511) may be less than the first target speed range. In this case, the wearable device (120) may perform at least one of an operation of determining a resistance intensity level (e.g., first resistance intensity level -1) of a second resistance section (521) by applying a second level value (e.g., -1) to a first resistance intensity level of a first resistance section (511), an operation of determining a target speed (e.g., first target speed -0.5) of a second resistance section (521) by applying a second speed value (e.g., -0.5) to a first target speed of the first resistance section (511), or an operation of determining a target time (e.g., first target time -30) of a second resistance section (521) by applying a second time value (e.g., -30 seconds) to a first target time of the first resistance section (511).

[0137] According to one embodiment, the user's heart rate information (or average heart rate information) in the first resistance zone (511) may belong to Zone 5. In this case, the wearable device (120) may perform at least one of an operation of determining a resistance intensity level (e.g., first resistance intensity level -1) of the second resistance zone (521) by applying a second level value (e.g., -1) to the first resistance intensity level of the first resistance zone (511), an operation of determining a target speed (e.g., first target speed -0.5) of the second resistance zone (521) by applying a second speed value (e.g., -0.5) to the first target speed of the first resistance zone (511), or an operation of determining a target time (e.g., first target speed -30) of the second resistance zone (521) by applying a second time value (e.g., -30 seconds) to the first target time of the first resistance zone (511). When the user's heart rate information (or average heart rate information) in the first resistance section (511) belongs to Zone 5, the wearable device (120) can perform at least one of an operation of determining a resistance intensity level of the second resistance section (521) to be lower than the first resistance intensity level, an operation of determining a target speed of the second resistance section (521) to be lower than the first target speed, or an operation of determining a target time of the second resistance section (521) to be shorter than the first target time, regardless of whether the first walking speed in the first resistance section (511) is outside the first target speed range.

[0138] In the example illustrated in FIG. 6, the wearable device (120) can determine the target speed of the second auxiliary section (522) based on the target speed of the second resistance section (521). For example, the wearable device (120) can determine the target speed of the second auxiliary section (522) by multiplying the target speed of the second resistance section (521) by a ratio (e.g., a first ratio or a second ratio).

[0139] In the example illustrated in FIG. 6, the wearable device (120) can determine the assistance intensity level of the second assistance section (522) based on the first walking speed in the first assistance section (512), the user's heart rate information in the first assistance section (512), and the target speed of the second assistance section (522).

[0140] For example, the target speed of the second assist section (522) may be 4.5 km / h. The wearable device (120) may obtain an assist intensity level (e.g., 2) corresponding to the target speed (e.g., 4.5 km / h) of the second assist section (522) from a table (610) in which assist intensity levels and exercise speed ranges are mapped.

[0141] The user's heart rate information (or average heart rate information) in the first assist section (512) may belong to Zone 1 (or Zone 2 or Zone 3 or Zone 4), and the user's walking speed in the first assist section (512) may exceed the target speed range of the first assist section (512). In this case, the wearable device (120) may apply a second level value (e.g., -1) to the acquired assist intensity level (e.g., 2) to determine the assist intensity level (e.g., acquired assist intensity level -1) of the second assist section (522). The user's heart rate information (or average heart rate information) in the first assist section (512) may belong to Zone 1 (or Zone 2 or Zone 3), and the user's walking speed in the first assist section (512) may be less than the target speed range of the first assist section (512). In this case, the wearable device (120) may determine the assistance intensity level (e.g., the assistance intensity level obtained +1) of the second assistance section (522) by applying the first level value (e.g., +1) to the acquired assistance intensity level (e.g., 2). The heart rate information (or average heart rate information) of the user of the first assistance section (512) may belong to Zone 1 (or Zone 2 or Zone 3) and the walking speed of the user in the first assistance section (512) may be within the target speed range of the first assistance section (512). In this case, the wearable device (120) may determine the acquired assistance intensity level (e.g., 2) as the assistance intensity level of the second assistance section (522).

[0142] The user's heart rate information (or average heart rate information) in the first auxiliary zone (512) may belong to Zone 5. In this case, the wearable device (120) may apply a second level value (e.g., -1) to the acquired auxiliary intensity level (e.g., 2) to determine the auxiliary intensity level (e.g., acquired auxiliary intensity level -1) of the second auxiliary zone (522).

[0143] In the example illustrated in FIG. 6, the target time of the second resistance section (521) may be longer than the first target time of the first resistance section (511) by a certain period of time (e.g., 30 seconds). In this case, the wearable device (120) may determine the target time of the second auxiliary section (522) by deducting the certain period of time (e.g., 30 seconds) from the target time of the first auxiliary section (512). The second target time of the second resistance section (521) may be shorter than the first target time of the first resistance section (511) by a certain period of time (e.g., 30 seconds). In this case, the wearable device (120) may determine the target time of the second auxiliary section (522) by adding the certain period of time (e.g., 30 seconds) to the target time of the first auxiliary section (512).

[0176] Referring to FIG. 8, a wearable device (120) according to one embodiment may provide a user with an exercise program (500) (e.g., a first exercise program). The embodiments described with reference to FIGS. 8 to 10 may also be applied to a case where a user performs a second exercise program.

[0177] According to one embodiment, the first exercise program may include a plurality of sets (810 to 840).

[0178] According to one embodiment, the resistance section of 1set (810) may be set with a resistance intensity level (e.g., 4), a target speed (e.g., 6 km / h), and a target time (e.g., 4 minutes 30 seconds). The assistance section of 1set (810) may be set with an assistance intensity level (e.g., 3), a target speed (e.g., 4.8 km / h), and a target time (e.g., 3 minutes). The resistance section of 1set (810) may correspond to a starting resistance section, and the assistance section of 1set (810) may correspond to a starting assistance section.

[0179] According to one embodiment, the wearable device (120) can provide a resistance torque (or resistance force) to the user in the resistance section of 1set (810) and can provide an assist torque (or assist force) to the user in the assist section of 1set (810).

[0180] According to one embodiment, the wearable device (120) can determine the resistance intensity level, target speed, and target time of the resistance section of 2 sets (820), and can determine the assistance intensity level, target speed, and target time of the assistance section of 2 sets (820).

In this case, the wearable device (120) may determine the resistance intensity level of the resistance section of 2 set (820) as 5, the target speed of the resistance section of 2 set (820) as 6.0 km / h, and the target time of the resistance section of 2 set (820) as 4 minutes and 30 seconds.

[0182] According to one embodiment, the wearable device (120) may multiply the target speed (e.g., 6.0 km / h) of the resistance section of the 2nd set (820) by a first ratio (e.g., 0.8) to determine the target speed of the assistance section of the 2nd set (820) as 4.8 km / h. The wearable device (120) may obtain an assistance intensity level (e.g., 3) corresponding to the target speed (e.g., 4.8 km / h) of the assistance section of the 2nd set (820) from the table (610).

In this case, the wearable device (120) can determine the assist intensity level of the assist section of 2set (820) as 2 by applying a second level value (e.g., -1) to the acquired assist intensity level (e.g., 3). The wearable device (120) can determine the target time of the assist section of 2set (820) as 3 minutes by subtracting the target time (e.g., 4 minutes 30 seconds) of the resistance section of 2set (820) from the set time (e.g., 7 minutes 30 seconds).

Since the resistance intensity level of the resistance section of the 2nd set (820) may be the maximum resistance intensity level (e.g., 5), the wearable device (120) may determine the resistance intensity level of the resistance section of the 3rd set (830) as 5. The wearable device (120) may apply a first speed value (e.g., +0.5) to the target speed (e.g., 6 km / h) of the resistance section of the 2nd set (820) to determine the target speed of the resistance section of the 3rd set (830) as 6.5 km / h.

In this case, the wearable device (120) can determine the assist intensity level of the assist section of the 2nd set (820) as 2 by applying a second level value (e.g., -1) to the acquired assist intensity level (e.g., 3). The wearable device (120) can determine the target time of the assist section of the 3rd set (830) as 3 minutes by subtracting the target time (e.g., 4 minutes 30 seconds) of the resistance section of the 3rd set (830) from the set time (e.g., 7 minutes 30 seconds).

The wearable device (120) may determine the target speed of the resistance section of the 4th set (840) as 6.5 km / h without changing the speed because the target speed of the 3rd set (830) may correspond to the maximum target speed. The wearable device (120) can determine the target time of the resistance section of the 4th set (840) as 5 minutes by applying a first time value (e.g., +30) to the target time (e.g., 4 minutes 30 seconds) of the resistance section of the 3rd set (830).

The wearable device (120) may determine the assist intensity level of the assist section of the 4th set (1040) as 2, which is the same as the assist intensity level of the assist section of the 3rd set (1030). The wearable device (120) may determine the target time of the assist section of the 4th set (1040) as 3 minutes by subtracting the target time (e.g., 4 minutes 30 seconds) of the resistance section of the 4th set (1040) from a predetermined time (e.g., 7 minutes 30 seconds).

[0219] According to one embodiment, the wearable device (120) can provide the user with a resistance torque corresponding to a resistance intensity level (e.g., 1) in the resistance section of 4 sets (1040), and can provide the user with an assist torque corresponding to an assist intensity level (e.g., 2) in the assist section of 4 sets (1040).

[0220]

[0221] FIG. 11 is a drawing illustrating an example of the operation of a wearable device according to one embodiment.

[0222] Referring to FIG. 11, a wearable device (120) according to one embodiment can provide an exercise program (500) to a user.

[0223] According to one embodiment, the exercise intensity (1110) of the last set of the exercise program (500) may include, for example, a resistance intensity level (e.g., 5) and a target speed (e.g., 5 km / h) of the resistance section of the last set and an assistance intensity level (e.g., 3) and a target speed (e.g., 4 km / h) of the assistance section of the last set.

[0224] According to one embodiment, when the user's exercise is finished (or the exercise program (500) is finished), the wearable device (120) may determine the exercise intensity (1110) of the last set of the exercise program (500) as the exercise intensity of one set of the exercise program (500) (e.g., resistance intensity level of the resistance section = 5, target speed of the resistance section = 5 km / h, assistance intensity level of the assistance section = 3, target speed of the assistance section = 4 km / h). When the user re-performs the exercise program (500), the wearable device (120) may provide the user with a resistance torque corresponding to the resistance intensity level (e.g., 5) in one set of the resistance section of the re-performed exercise program (500), and may provide the user with an assistance torque corresponding to the assistance intensity level (e.g., 3) in one set of the assistance section.

[0225] According to one embodiment, the wearable device (120) may receive a user response (e.g., a response regarding the exercise intensity of the exercise program (500)) from the user when the user's exercise is finished (or when the exercise program (500) is finished). For example, the wearable device (120) may receive a first response (1121) indicating to increase the exercise intensity of the exercise program (500) (e.g., “Raise” in FIG. 11) from the user when the user's exercise is finished, a second response (1122) indicating to maintain the exercise intensity of the exercise program (500) (e.g., “As is” in FIG. 11), or a third response (1123) indicating to decrease the exercise intensity of the exercise program (500) (e.g., “Lower” in FIG. 11).

[0226] According to one embodiment, the wearable device (120) can determine one set of exercise intensities (e.g., exercise intensity (1131), exercise intensity (1132), or exercise intensity (1133) of FIG. 11) of an exercise program (500) based on the exercise intensity (1110) and a user response (e.g., a first response (1121), a second response (1122), or a third response (1123)).

[0227] For example, when the wearable device (120) receives a first response (1121) from the user, the wearable device (120) may determine the exercise intensity (1131) of one set of the exercise program (500) by adjusting the exercise intensity (1110) to a higher level. For example, the wearable device (120) may determine a resistance intensity level higher than the resistance intensity level of the exercise intensity (1110) as the resistance intensity level of the resistance section of one set. When the resistance intensity level of the exercise intensity (1110) is the maximum resistance intensity level, the wearable device (120) may determine a speed higher than the target speed of the resistance section of the exercise intensity (1110) as the target speed of the resistance section of one set. The wearable device (120) may determine the target speed of the auxiliary section of one set based on the target speed of the resistance section of one set. As in the exercise intensity (1131) of FIG. 11, the wearable device (120) can determine the resistance intensity level of one set of resistance sections of the exercise program (500) as 5 (e.g., the same level as the resistance intensity level of the exercise intensity (1110)), and the target speed of one set of resistance sections as 5.5 km / h (e.g., a speed that is 0.5 km / h higher than the target speed of the resistance section of the exercise intensity (1110)). The wearable device (120) can determine the target speed of one set of assistance sections of the exercise program (500) as 4.4 km / h (e.g., the result of multiplying 5.5 km / h by the first ratio). The wearable device (120) can determine the assistance intensity level (e.g., 3) of the assistance section of the exercise intensity (1110) as the assistance intensity level (e.g., 3) of one set of assistance sections of the exercise program (500).

[0228] For another example, if the wearable device (120) receives a second response (1122) from the user, the wearable device (120) may determine the exercise intensity (1110) as one set of exercise intensities (1132) of the exercise program (500). The exercise intensity (1132) and the exercise intensity (1110) may be the same. If the wearable device (120) does not receive a response from the user regarding the exercise intensity of the exercise program (500), the wearable device (120) may determine the exercise intensity (1110) as one set of exercise intensities (1132) of the exercise program (500).

[0229] For another example, when the wearable device (120) receives a third response (1123) from the user, the wearable device (120) may determine the exercise intensity (1133) of one set of the exercise program (500) by lowering the exercise intensity (1110). For example, the wearable device (120) may determine a resistance intensity level lower than the resistance intensity level of the exercise intensity (1110) as the resistance intensity level of the resistance section of one set. When the resistance intensity level of the exercise intensity (1110) is the minimum resistance intensity level, the wearable device (120) may determine a speed lower than the target speed of the resistance section of the exercise intensity (1110) as the target speed of the resistance section of one set. As in the exercise intensity (1133) of FIG. 11, the wearable device (120) can determine the resistance intensity level of one set of resistance sections of the exercise program (500) as 4 (e.g., a level 1 lower than the resistance intensity level of the resistance section of the exercise intensity (1110)) and the target speed as 5 km / h (e.g., the same speed as the target speed of the resistance section of the exercise intensity (1110)). The wearable device (120) can determine the target speed of one set of assistance sections of the exercise program (500) as 4 km / h (e.g., the result of multiplying 5 km / h by the first ratio), and the assistance intensity level (e.g., 3) of the exercise intensity (1110) can be determined as the assistance intensity level (e.g., 3) of one set of assistance sections of the exercise program (500).

[0230]

[0231] FIG. 12 is a diagram illustrating another example of an exercise program provided by a wearable device according to one embodiment.

[0232] Referring to FIG. 12, an exercise program (1200) according to an embodiment (hereinafter referred to as a “third exercise program”) may represent an exercise program that allows a user to perform a walking exercise without coaching (or guidance) of a wearable device (120) and a walking exercise provided with coaching (or guidance) of a wearable device (120). “Coaching (or guidance)” may represent, for example, an action of the wearable device (120) providing assistance (e.g., visual assistance and / or auditory assistance) to the user so that the user’s exercise can reach a goal. The visual assistance may include, for example, an action of the wearable device (120) displaying information regarding the achievement of the user’s exercise goal (e.g., a comparison between the user’s walking speed and the target speed, etc.) on the display of the electronic device (110) (or smartwatch (132)). Auditory assistance may include, for example, the wearable device (120) providing the user with information about the user's progress toward achieving a goal of their exercise (e.g., a comparison between the user's walking speed and a goal speed) audibly through one or more speakers or wireless earphones (131) of the wearable device (120).

[0233] The third exercise program (1200) may include periods in which the wearable device (120) does not provide coaching to the user and periods in which the wearable device (120) provides coaching to the user. The term "period" may, for example, represent a time interval. The length of the interval may be determined based on a target time value of the interval. The period in which the wearable device (120) does not provide coaching to the user is referred to as an "uncoached interval," and the period in which the wearable device (120) provides coaching to the user is referred to as a "coached interval." When the uncoached interval (e.g., a time interval in which the wearable device (120) does not provide coaching) ends, the coached interval (e.g., a time interval in which the wearable device (120) provides coaching) may begin, and when the coached interval ends, the uncoached interval may begin. The uncoached interval and the coached interval may proceed alternately. Pairs consisting of the uncoached interval and the coached interval may be repeated.

[0234] The uncoached section of the third exercise program (1200) may correspond to, for example, a section in which the wearable device (120) determines the user's walking characteristics (or walking habits) (e.g., walking speed, stride length, walking posture, etc.). In the uncoached section, the wearable device (120) may provide an assistive torque to the user, thereby allowing the user to perform walking exercise with the help of the assistive torque. In the uncoached section, the wearable device (120) may determine the user's usual walking characteristics and collect information necessary for coaching in the coaching section (e.g., target speed of the coaching section, etc.). The wearable device (120) may determine the user's walking characteristics based on sensor data from sensors (e.g., angle sensors (320, 320-1) and / or IMU (360)) in the uncoached section. Each of the assisted section 1 (1210) and the assisted section 3 (1230) described below may correspond to an uncoached section.

[0235] The coaching section of the third exercise program (1200) may correspond to a section in which, for example, the wearable device (120) provides the user with information about the gait characteristics identified in the non-coaching section (e.g., voice-based) and performs coaching (e.g., voice-based coaching) to help the user's walking reach a target speed. In the coaching section, the wearable device (120) may provide the user with coaching and assistive torque to assist the user's walking, thereby correcting the user's incorrect walking posture and improving the user's physical strength. Each of the assisting section 2 (1220) and the assisting section 4 (1240) described below may correspond to a coaching section.

[0236] The third exercise program (1200) may be, for example, an exercise program for improving the user's walking speed. The target speed in the first uncoached section (e.g., assistance section 1 (1210)) may be set (or determined) to be 120% of the user's usual walking speed (e.g., the walking speed calculated based on the results of a 10-minute walk test (MWT) performed after the start of the third exercise program (1200)). The wearable device (120) may audibly transmit the target speed of the first uncoached section to the user in the first uncoached section. In the first uncoached section, the user may perform walking exercise while receiving assistance torque (e.g., assistance torque corresponding to assistance intensity level 2 described below) from the wearable device (120). The target speed and assistance intensity level of the first coaching section (e.g., assistance section 2 (1220)) may be determined differently depending on whether the user's walking speed in the first non-coaching section is outside the target speed range of the first non-coaching section or within the target speed range. If the user's walking speed in the first non-coaching section is lower than the target speed range, the wearable device (120) may determine the target speed of the first coaching section to be lower than the target speed of the first non-coaching section and may determine the assistance intensity level of the first coaching section to be lower than the basic assistance intensity level (e.g., 2) of the first coaching section. In the first coaching section, the user may perform walking exercise while receiving assistance torque (e.g., assistance torque corresponding to assistance intensity level 2) from the wearable device (120). At this time, the wearable device (120) may convey the user's lowered walking speed to the user through voice and may provide coaching (e.g., voice coaching) to the user so that the user's lowered walking speed can reach the target speed.

[0237] The third exercise program (1200) may be, for example, an exercise program that can maintain a fast walking speed of the user and improve the user's basic physical strength. Even if the user's walking speed in the first uncoached section (e.g., assistance section 1 (1220)) is lowered because the target speed of the first coached section (e.g., assistance section 2 (1220)) is lowered, the target speed of the second uncoached section (e.g., assistance section 3 (1230)) may be determined (or set) to the same value as the target speed of the first uncoached section (e.g., 120% of the user's usual walking speed). Accordingly, the user can walk at a fast speed in the second uncoached section, and the user's basic physical strength can be improved through the performance of the fast walking. The target speed and assistance intensity level of the second coaching section (e.g., assistance section 4 (1240)) may be determined differently depending on whether the user's walking speed in the second non-coaching section is outside the target speed range of the second non-coaching section or within the target speed range. Therefore, the target speed and / or assistance intensity level of the second coaching section may be determined to have different values ​​than the target speed and / or assistance intensity level of the first coaching section. By alternating between (i) and (ii) (wherein (i) represents the operation of the wearable device (120) and the user's exercise in the non-coaching section and (ii) represents the operation of the wearable device (120) and the user's exercise in the coaching section), the user can perform the walking training until he / she reaches the initially set target speed (e.g., 120% of the user's usual walking speed).

[0238] The wearable device (120) can provide an assistive torque (e.g., an assistive torque corresponding to the assistive intensity level of the non-coaching section) to the user in the non-coaching section of the third exercise program (1200), identify the user's walking characteristics, and determine a target and an assistive intensity level of the next section (i.e., a coaching section) of the non-coaching section based on the identified walking characteristics. The wearable device (120) can provide coaching and an assistive torque (e.g., an assistive torque corresponding to the assistive intensity level of the coaching section) to the user in the coaching section so that the user's walking can reach or maintain the target (or so that the user's walking speed can improve) in the coaching section of the third exercise program (1200). The wearable device (120) can alternately and repeatedly perform movements in the non-coaching section and movements in the coaching section. Accordingly, the wearable device (120) can improve the walking ability and physical strength of the user performing the third exercise program (1200).

[0239] Hereinafter, the operation of the wearable device (120) will be described with reference to FIG. 12.

[0240] According to one embodiment, the wearable device (120) can support multiple assist intensity levels (e.g., 1 to 5). The wearable device (120) can provide a greater intensity of assist torque to the user as the assist intensity level increases.

[0241] According to one embodiment, the wearable device (120) may determine the user's target speed (e.g., target walking speed) in the target setting section (1205) when the third exercise program (1200) starts. For example, the wearable device (120) may perform 10 MWT to calculate the distance the user walked for 10 minutes. The wearable device (120) may calculate the walking speed based on the result of performing the 10 MWT (e.g., the distance the user walked for 10 minutes) and may multiply the calculated walking speed by a ratio (e.g., 1.2) to determine the user's target speed. In the example illustrated in FIG. 12, the wearable device (120) may determine the target speed as 5 km / h.

[0242] According to one embodiment, the wearable device (120) may determine an assist intensity level (e.g., 2), a target speed (e.g., 5 km / h), and a target time (e.g., 2 minutes 30 seconds) as the exercise intensity of assist section 1 (1210). The assist intensity level (e.g., 2) and the target time (e.g., 2 minutes 30 seconds) of assist section 1 (1210) may be preset (or specified). The target time (e.g., 2 minutes 30 seconds) may correspond to the length of assist section 1 (1210). Without being limited thereto, the wearable device (120) may determine the assist intensity level (e.g., 2) and the target time (e.g., 2 minutes 30 seconds) of the assist section 1 (1210) based on user input (e.g., a user input setting the assist intensity level (e.g., 2) of the assist section 1 (1210) and a user input setting the target time (e.g., 2 minutes 30 seconds) of the assist section 1 (1210). The wearable device (120) may provide the user with an assist torque corresponding to the assist intensity level (e.g., 2) in the assist section 1 (1210).

[0243] According to one embodiment, the wearable device (120) may provide a message, in an auditory manner (e.g., voice) and / or a visual manner (e.g., on a display of the electronic device (110 or 132)), indicating that it has identified a description of the third exercise program (1200) and / or a gait characteristic (or gait habit) of the user (e.g., at least one of walking speed, stride length, or gait symmetry) in the auxiliary section 1 (1210). The gait symmetry may be, for example, a value indicating the degree to which the user's walking by the right leg and the walking by the left leg are symmetrical. The wearable device (120) may provide a description of the third exercise program (1200) in the auxiliary section 1 (1210) of the first set of the third exercise program (1200), and may not provide the description in the auxiliary section 1 (1210) of a subsequent set of the third exercise program (1200). The wearable device (120) may not provide coaching to the user in auxiliary section 1 (1210).

[0244] Table 4 below shows examples of sentences that the wearable device (120) provides to the user through voice in auxiliary section 1 (1210). Sentence 1 in Table 4 below may include a description of the third exercise program (1200) and a message indicating that the user's gait characteristics have been identified.

[0245]

[0246] The wearable device (120) can provide sentence 1 and / or sentence 2 of Table 4 above to the user by voice in auxiliary section 1 (1210).

[0247] According to one embodiment, the wearable device (120) can determine whether the user's walking speed in auxiliary section 1 (1210) falls within the target speed range of auxiliary section 1 (1210) (e.g., target speed of auxiliary section 1 (1210) ±5 km / h).

[0248] According to one embodiment, the wearable device (120) may determine the target speed (e.g., 5 km / h) of the assist section 1 (1210) as the target speed (e.g., 5 km / h) of the assist section 2 (1220) when the user's walking speed in the assist section 1 (1210) falls within the target speed range of the assist section 1 (1210). The wearable device (120) may determine a level higher than the assist intensity level (e.g., 2) of the assist section 1 (1210) as the assist intensity level (e.g., 3) of the assist section 2 (1220).

[0249] According to one embodiment, the wearable device (120) may determine a target speed (e.g., 5.5 km / h) of the assist section 2 (1220) by applying a first speed value (e.g., +0.5) to the target speed (e.g., 5 km / h) of the assist section 1 (1210) when the user's walking speed in the assist section 1 (1210) exceeds the target speed range of the assist section 1 (1210). The wearable device (120) may determine a higher level than the assist intensity level (e.g., 2) of the assist section 1 (1210) as the assist intensity level (e.g., 4) of the assist section 2 (1220).

[0250] According to one embodiment, the wearable device (120) may determine the target speed (e.g., 4.5 km / h) of the assist section 2 (1220) by applying a second speed value (e.g., -0.5) to the target speed (e.g., 5 km / h) of the assist section 1 (1210) when the user's walking speed in the assist section 1 (1210) is less than the target speed range of the assist section 1 (1210). The wearable device (120) may determine the assist intensity level (e.g., 2) of the assist section 1 (1210) as the assist intensity level (e.g., 4) of the assist section 2 (1220).

[0251] According to one embodiment, each of the auxiliary sections (1210, 1230) may have an auxiliary intensity level (e.g., 2) set (or designated) as a default auxiliary intensity level, and each of the auxiliary sections (1220, 1240) may have an auxiliary intensity level (e.g., 3) set (or designated) as a default auxiliary intensity level. When the user's walking speed in the auxiliary section 1 (1210) exceeds the target speed range of the auxiliary section 1 (1210), the wearable device (120) may adjust the default auxiliary intensity level (e.g., 3) of the auxiliary section 2 (1220) higher to determine the auxiliary intensity level (e.g., 4) of the auxiliary section 2 (1220). The wearable device (120) can maintain the basic assistance intensity level of the assistance section 2 (1220) when the user's walking speed in the assistance section 1 (1210) is within the target speed range of the assistance section 1 (1210). The wearable device (120) can determine the assistance intensity level (e.g., 2) of the assistance section 2 (1220) by lowering the basic assistance intensity level of the assistance section 2 (1220) when the user's walking speed in the assistance section 1 (1210) is less than the target speed range of the assistance section 1 (1210).

[0252] According to one embodiment, the target time of auxiliary section 2 (1220) may be predetermined (or specified). As in the example illustrated in FIG. 12, the target time of auxiliary section 2 (1220) may be predetermined (or specified) as, for example, 5 minutes, but is not limited thereto. According to one embodiment, the wearable device (120) may determine (or set) the target time of auxiliary section 2 (1220) based on a user input (e.g., a user input setting the target time of auxiliary section 2 (1220) (e.g., 5 minutes)).

[0253] According to one embodiment, the wearable device (120) may provide an assist torque to the user in the assist section 2 (1220) (e.g., an assist torque corresponding to an assist intensity level 4, an assist torque corresponding to an assist intensity level 3, or an assist torque corresponding to an assist intensity level 2).

[0254] According to one embodiment, the wearable device (120) may provide the user with gait characteristics (e.g., at least one of walking speed, stride length, or gait symmetry) and / or coaching detected during the assistance segment 1 (1210) in an auditory manner (e.g., voice) and / or a visual manner (e.g., displayed on a display of the electronic device (110 or 132)) in the assistance segment 2 (1220).

[0255] Table 5 below shows examples of sentences that the wearable device (120) provides to the user through voice in auxiliary section 2 (1220).

[0256]

[0257] The wearable device (120) can provide sentence 1 and / or sentence 2 of Table 5 above to the user by voice in auxiliary section 2 (1220).

[0258] According to one embodiment, the wearable device (120) may determine the target speed of the auxiliary section 3 (1230) based on the target speed of the auxiliary section 2 (1220). For example, if the target speed of the auxiliary section 2 (1220) is 5 km / h, the wearable device (120) may determine the target speed of the auxiliary section 3 (1230) as 5 km / h. If the target speed of the auxiliary section 2 (1220) is 5.5 km / h, the wearable device (120) may determine the target speed of the auxiliary section 3 (1230) as 5.5 km / h. If the target speed of the auxiliary section 2 (1220) is 4.5 km / h, the wearable device (120) may determine the target speed of the auxiliary section 3 (1230) as 4.5 km / h. The target speed of auxiliary section 3 (1230) may be, for example, the same as the target speed of auxiliary section 2 (1220).

[0259] Depending on the implementation, the target speed of auxiliary section 3 (1230) may be the same as the target speed of auxiliary section 1 (1210).

[0260] According to one embodiment, the auxiliary intensity level (e.g., 2) and target time (e.g., 2 minutes 30 seconds) of auxiliary section 3 (1230) may be preset (or designated). Without being limited thereto, the wearable device (120) may set (or determine) the auxiliary intensity level and target time of auxiliary section 3 (1230) based on user input. The auxiliary intensity level and target time of auxiliary section 3 (1230) may be the same as the auxiliary intensity level and target time of auxiliary section 1 (1210).

[0261] According to one embodiment, the wearable device (120) can determine whether the user's walking speed in the assist section 3 (1230) falls within the target speed range of the assist section 3 (1230) (e.g., target speed of the assist section 3 (1230) ±5 km / h). The wearable device (120) can provide an assist torque (e.g., an assist torque corresponding to an assist intensity level 2) to the user in the assist section 3 (1230).

[0262] In one embodiment, the wearable device (120) may provide the user with a description of the assist section 3 (1230) (e.g., a target speed of the assist section 3 (1230)) and / or a message indicating that the wearable device has identified the user's gait characteristics in an auditory manner (e.g., voice) and / or a visual manner (e.g., on a display of the electronic device (110 or 132)) in assist section 3 (1230). Depending on the implementation, the wearable device (120) may not provide the user with a message indicating that the wearable device has identified the user's gait characteristics in assist section 3 (1230). The wearable device (120) may not provide coaching to the user in assist section 3 (1230).

[0263] According to one embodiment, the wearable device (120) may determine the target speed (e.g., 5 km / h in FIG. 12) of the assist section 3 (1230) as the target speed (e.g., 5 km / h) of the assist section 4 (1240) when the user's walking speed in the assist section 3 (1230) falls within the target speed range of the assist section 3 (1230). The wearable device (120) may determine a level higher than the assist intensity level (e.g., 2) of the assist section 3 (1230) as the assist intensity level (e.g., 3) of the assist section 4 (1240).

[0264] According to one embodiment, the wearable device (120) may determine the target speed (e.g., 5.5 km / h) of the assist section 4 (1240) by applying a first speed value (e.g., +0.5) to the target speed (e.g., 5 km / h) of the assist section 3 (1230) when the user's walking speed in the assist section 3 (1230) exceeds the target speed range of the assist section 3 (1230). The wearable device (120) may determine a higher level than the assist intensity level (e.g., 2) of the assist section 3 (1230) as the assist intensity level (e.g., 5 or 4) of the assist section 4 (1240).

[0265] According to one embodiment, the wearable device (120) may determine the target speed (e.g., 4.5 km / h) of the assist section 4 (1240) by applying a second speed value (e.g., -0.5) to the target speed (e.g., 5 km / h) of the assist section 3 (1230) when the user's walking speed in the assist section 3 (1230) is less than the target speed range of the assist section 3 (1230). The wearable device (120) may determine the assist intensity level (e.g., 2) of the assist section 3 (1230) as the assist intensity level (e.g., 4) of the assist section 4 (1240).

[0266] According to one embodiment, the wearable device (120) may determine the assist intensity level (e.g., 5 or 4) of assist section 4 (1240) by adjusting the basic assist intensity level (e.g., 3) of assist section 4 (1240) higher when the user's walking speed in assist section 3 (1230) exceeds the target speed range of assist section 3 (1210). The wearable device (120) may maintain the basic assist intensity level (e.g., 3) of assist section 4 (1220) when the user's walking speed in assist section 3 (1230) is within the target speed range of assist section 3 (1230). The wearable device (120) can determine the assistance intensity level (e.g., 2) of assistance section 4 (1240) by lowering the basic assistance intensity level of assistance section 4 (1220) when the user's walking speed in assistance section 3 (1230) is below the target speed range of assistance section 3 (1230).

[0267] According to one embodiment, the target time of auxiliary section 4 (1240) may be predetermined (or specified). The target time of auxiliary section 4 (1240) may be the same as or different from the target time of auxiliary section 2 (1220). According to one embodiment, the wearable device (120) may determine the target time of auxiliary section 4 (1240) based on a user input (e.g., a user input setting a target time of auxiliary section 4 (1240) (e.g., 5 minutes)).

[0268] According to one embodiment, the wearable device (120) may provide the user with gait characteristics and / or coaching acquired during assist section 3 (1230) in an auditory manner (e.g., voice) and / or visual manner (e.g., display on a display of the electronic device (110 or 132)) in assist section 4 (1240).

[0269] Auxiliary sections 1 (1210) to 4 (1240) may correspond to one set of the third exercise program (1200). Auxiliary sections 1 (1210) to 4 (1240) described with reference to FIG. 12 may correspond, for example, to auxiliary sections 1 (1210) to 4 (1240) of the first set of the third exercise program (1200). The wearable device (120) may determine the target speed of auxiliary section 1 (1210) of the second set based on the target speed of auxiliary section 4 (1240) of the first set. For example, the target speed of auxiliary section 1 (1210) of the second set may be the same as the target speed of auxiliary section 4 (1240) of the first set. The auxiliary intensity level and target time of auxiliary section 1 (1210) of the first set may be the same as the auxiliary intensity level and target time of auxiliary section 1 (1210) of the second set, respectively. The description of auxiliary sections 2 (1220), 3 (1230), and 4 (1240) of the first set, respectively, may be applied to auxiliary sections 2 (1220), 3 (1230), and 4 (1240) of the second set, respectively.

[0273] A wearable device (120) according to one embodiment may provide a user with an exercise program (hereinafter referred to as a “fourth exercise program”) having a pattern (1310, 1320, 1330, 1340, 1350, or 1360). The wearable device (120) may provide a user with an exercise program in which an intensity level related to the magnitude of a torque changes according to the pattern (1310, 1320, 1330, 1340, 1350, or 1360).

[0274] In one embodiment, an intensity level greater than 0 (or an intensity level having a positive value) may correspond to an auxiliary intensity level, and an intensity level less than 0 (or an intensity level having a negative value) may correspond to a resistance intensity level.

[0275] According to one embodiment, the wearable device (120) can provide a user with a fourth exercise program (or a torque according to the first pattern (1310)) having a first pattern (1310). The first pattern (1310) can be, for example, a pattern in which an assistance intensity level increases (e.g., linearly increases) from time (t1) to time (t2) and decreases (e.g., linearly decreases) from time (t2) to time (t3), and a resistance intensity level increases (e.g., linearly increases) from time (t3) to time (t4) and decreases (e.g., linearly decreases) from time (t4) to time (t5).

[0276] According to one embodiment, the wearable device (120) can provide a fourth exercise program (or torque according to the second pattern (1320)) to the user having a second pattern (1320). The second pattern (1320) can be, for example, a pattern in which a resistance intensity level increases (e.g., linearly increases) from time t1 to time t2 and decreases (e.g., linearly decreases) from time t2 to time t3, and an assistance intensity level increases (e.g., linearly increases) from time t3 to time t4 and decreases (e.g., linearly decreases) from time t4 to time t5.

[0277] According to one embodiment, the wearable device (120) can provide a user with a fourth exercise program (or a torque according to the third pattern (1330)) having a third pattern (1330). The third pattern (1330) can be, for example, a pattern in which the assistance intensity level increases (e.g., linearly increases) from time (t1) to time (t2), decreases (e.g., linearly decreases) from time (t2) to time (t3), increases (e.g., linearly increases) from time (t3) to time (t4), and decreases (e.g., linearly decreases) from time (t4) to time (t5).

[0278] According to one embodiment, the wearable device (120) can provide a user with a fourth exercise program (or a torque according to the fourth pattern (1340)) having a fourth pattern (1340). The fourth pattern (1340) can be, for example, a pattern in which a resistance intensity level increases (e.g., linearly increases) from time (t1) to time (t2), decreases (e.g., linearly decreases) from time (t2) to time (t3), increases (e.g., linearly increases) from time (t3) to time (t4), and decreases (e.g., linearly decreases) from time (t4) to time (t5).

[0279] According to one embodiment, the wearable device (120) can provide a user with a fourth exercise program (or a torque according to the fifth pattern (1350)) having a fifth pattern (1350). The fifth pattern (1350) can be, for example, a pattern in which the assistance intensity level increases (e.g., linearly increases) from time (t1) to time (t2), is maintained from time (t2) to time (t3), and decreases (e.g., linearly decreases) from time (t3) to time (t4).

[0280] According to one embodiment, the wearable device (120) can provide a user with a fourth exercise program (or a torque according to the sixth pattern (1360)) having a sixth pattern (1360). The sixth pattern (1360) can be, for example, a pattern in which a resistance intensity level increases (e.g., linearly increases) from time (t1) to time (t2), is maintained from time (t2) to time (t3), and decreases (e.g., linearly decreases) from time (t3) to time (t4).

[0281] Referring to FIG. 14, an example of a seventh pattern (1410) with varying intensity levels is illustrated. According to one embodiment, the wearable device (120) may provide a user with a fourth exercise program having the seventh pattern (1410). The wearable device (120) may provide the user with a fourth exercise program with varying intensity levels according to the seventh pattern (1410).

[0282] According to one embodiment, the wearable device (120) can provide a fourth exercise program (or a torque according to the seventh pattern (1410)) to the user having a seventh pattern (1410). The seventh pattern (1410) can be, for example, a pattern in which an assistance intensity level increases (e.g., linearly increases) from time (t1) to time (t2), is maintained from time (t2) to time (t3), and decreases (e.g., linearly decreases) from time (t3) to time (t4), and a resistance intensity level increases (e.g., linearly increases) from time (t4) to time (t5), is maintained from time (t5) to time (t6), and decreases (e.g., linearly decreases) from time (t6) to time (t7).

[0283] In one embodiment, the fourth exercise program, in which the intensity level varies according to a pattern (e.g., at least one of the patterns 1310 to 1360 and 1410), may be an exercise program for providing entertainment to the user and / or providing various stimulation to the user (e.g., torque varying according to the pattern).

[0284] According to one embodiment, the wearable device (120) may provide voice coaching (or voice guidance) to the user while the fourth exercise program is being performed. For example, the wearable device (120) may provide the user with at least one of an explanation of the effects of walking exercise, guidance on proper walking posture, or exercise summary information (e.g., the user's distance traveled, number of steps, calories burned, etc.) via TTS.

[0285]

[0286] Figure 15 is a flowchart illustrating an operating method of a wearable device according to one embodiment.

[0287] Referring to FIG. 15, in operation 1510, a wearable device (120) according to an embodiment may provide a resistance torque to a user in a first resistance section (511) of an exercise program (500). A first resistance intensity level, a first target speed, and a first target time related to the intensity of the resistance torque provided in the first resistance section (511) may be set in the first resistance section (511). The exercise intensity of the first resistance section (511) may include, for example, the first resistance intensity level, the first target speed, and the first target time. The processor (310) of the wearable device (120) may control the drive module (30) so that a resistance torque is provided to the user in the first resistance section (511).

[0288] In operation 1520, the wearable device (120) (e.g., the processor (310)) may determine the user's first walking speed in the first resistance section. For example, the processor (310) may determine (or calculate) the user's first walking speed using sensing data from the IMU (360) and / or sensing data from the angle sensor (320 and / or 320-1).

[0289] In operation 1520, the wearable device (120) (e.g., processor (310)) may perform at least one of an operation of determining a resistance intensity level of a second resistance section (521) of an exercise program (500) by adjusting a first resistance intensity level, an operation of determining a target speed of the second resistance section (521) by adjusting a first target speed, or an operation of determining a target time of the second resistance section (521) by adjusting a first target time, when the first walking speed is outside a first target speed range.

[0290] For example, when the first walking speed exceeds the first target speed range, the processor (310) may perform at least one of an operation of determining a second resistance intensity level higher than the first resistance intensity level (e.g., the first resistance intensity level + 1) as the resistance intensity level of the second resistance section (521), an operation of determining a second target speed higher than the first target speed (e.g., the first target speed + 0.5) as the target speed of the second resistance section (521), or an operation of determining a second target time longer than the first target time (e.g., the first target time + 30 seconds) as the target time of the second resistance section (521). The processor (310) performs at least one of the following operations: when the first walking speed is less than the first target speed range, determining a third resistance intensity level (e.g., first resistance intensity level -1) lower than the first resistance intensity level as the resistance intensity level of the second resistance section (521); determining a third target speed (e.g., first target speed - 0.5) lower than the first target speed as the target speed of the second resistance section (521); or determining a third target time (e.g., first target time - 30 seconds) shorter than the first target time as the target time of the second resistance section (521).

[0291] According to one embodiment, the wearable device (120) (e.g., processor (310)) may determine a target speed of a first assist section (512) corresponding to a next section of the first resistance section (511) based on a first target speed. For example, the processor (310) may determine the target speed of the first assist section (512) by multiplying the first target speed by a ratio (e.g., a first ratio or a second ratio). The wearable device (120) (e.g., processor (310)) may determine a first assist intensity level related to an assist torque intensity in the first assist section (512) based on the target speed in the first assist section (512), and may determine a target time of the first assist section (512) based on the first target time.

[0292] In one embodiment, the ratio (e.g., the first ratio or the second ratio) may be based on the exercise program (500). For example, the first ratio may be based on the first exercise program, and the second ratio may be based on the second exercise program. When the first exercise program is performed, the processor (310) may multiply the first target speed by the first ratio to determine the target speed of the first auxiliary section (512) (e.g., first target speed * first ratio). When the second exercise program is performed, the processor (310) may multiply the first target speed by the second ratio to determine the target speed of the first auxiliary section (512) (e.g., first target speed * second ratio). Here, "*" may represent a multiplication sign.

[0293] According to one embodiment, the wearable device (120) (e.g., processor (310)) may determine a target speed in a second auxiliary section (522) corresponding to a next section of the second resistance section (521) based on the target speed of the second resistance section (521). If the second walking speed of the user in the first auxiliary section (512) exceeds a second target speed range (e.g., target speed of the first auxiliary section (512) ±0.5), the wearable device (120) (e.g., processor (310)) may determine a second assist intensity level higher than the assist intensity level corresponding to the target speed of the second assist section (522) as the assist intensity level of the second assist section (522). When the second walking speed is less than the second target speed range, the wearable device (120) (e.g., processor (310)) may determine a third assistance intensity level lower than the assistance intensity level corresponding to the target speed of the second assistance section (522) as the assistance intensity level of the second assistance section (522).

[0294] According to one embodiment, the wearable device (120) (e.g., processor (310)) may determine the resistance intensity level and target speed of the starting resistance section of the exercise program (500) based on the resistance intensity level and target speed of the last resistance section of the exercise program (500), when the exercise program (500) ends, and may determine the assistance intensity level and target speed of the starting assistance section of the exercise program (500) based on the assistance intensity level and target speed of the last assistance section of the exercise program (500).

[0295] According to one embodiment, the wearable device (120) (e.g., processor (310)) may receive a response (e.g., first response, second response, or third response) regarding the exercise intensity of the exercise program (500) from the user when the exercise program (500) ends. Based on the received response, the wearable device (120) (e.g., processor (310)) may adjust at least one of the resistance intensity level of the starting resistance section of the exercise program (500), the target speed of the starting resistance section of the exercise program (500), or the assistance intensity level of the starting assistance section of the exercise program (500).

[0296] According to one embodiment, the wearable device (120) (e.g., the processor (310)) may provide a third exercise program (1200) in which an uncoached segment (or first segment) (e.g., assisted segment 1 (1210) and / or assisted segment 3 (1230) of FIG. 12) and a coached segment (or second segment) (e.g., assisted segment 2 (1220) and / or assisted segment 4 (1240) of FIG. 12) alternately proceed. The uncoached segment may represent, for example, a segment in which the wearable device (120) provides an assistive torque (e.g., an assistive torque corresponding to an assistive intensity level of the uncoached segment) to the user, identifies the user's walking characteristics, and determines a target and an assistive intensity level of the next segment (i.e., the coached segment) of the uncoached segment based on the identified walking characteristics. The coached segment may represent, for example, a segment in which the wearable device (120) provides coaching and an assistive torque (e.g., a coaching) to the user so that the user's walking can reach or maintain a target (or so that the user's walking speed can improve). It can indicate a section that provides auxiliary torque corresponding to the auxiliary intensity level of the section.

[0297] According to one embodiment, the wearable device (120) (e.g., processor (310)) can provide a fourth exercise program in which an intensity level related to the magnitude of torque provided to the user varies according to a pattern (e.g., at least one of patterns (1310 to 1360 and 1410)).

[0298] According to one embodiment, the wearable device (120) (or the electronic device (110, 410) or the smart watch (132)) can receive the user's exercise purpose (e.g., high-intensity aerobic exercise, moderate-intensity aerobic exercise, walking training, exercise for fun, etc.) and recommend an exercise program to the user based on the user's exercise purpose. For example, the wearable device (120) (or the electronic device (110, 410) or the smart watch (132)) can recommend a first exercise program to the user when the user's exercise purpose indicates a first purpose (e.g., moderate-intensity aerobic exercise). The wearable device (120) (or the electronic device (110, 410) or the smart watch (132)) can recommend a second exercise program to the user when the user's exercise purpose indicates a second purpose (e.g., high-intensity aerobic exercise). The wearable device (120) (or the electronic device (110, 410) or the smart watch (132)) may recommend a third exercise program (1200) to the user if the user's exercise purpose indicates a third purpose (e.g., walking training). The wearable device (120) (or the electronic device (110, 410) or the smart watch (132)) may recommend a fourth exercise program to the user if the user's exercise purpose indicates a fourth purpose (e.g., exercising for fun).

[0299] According to one embodiment, the wearable device (120) may provide a user with a list of exercise programs including the first to fourth exercise programs. The wearable device (120) may provide the user with an exercise program selected by the user from among the exercise programs on the exercise program list. As another example, the electronic device (110, 410) or the smartwatch (132) may display a list of exercise programs on a display and transmit information about the exercise program selected by the user from among the exercise programs on the exercise program list to the wearable device (120). Based on the received information, the wearable device (120) may provide the exercise program selected by the user.

[0300] The embodiments described through FIGS. 1 to 14 can be applied to the operating method of the wearable device (120) of FIG. 15.

[0301]

[0302] According to one embodiment, a wearable device (120, 200, 300, 300-1) may include a driving module (30) that provides a torque to a user and a processing circuit, and a processor (310) that controls the driving module. The processor may control the driving module so that a resistance torque is provided to the user in a first resistance section of an exercise program (a first resistance intensity level, a first target speed, and a first target time related to the intensity of the resistance torque may be set in the first resistance section). The processor may determine a first walking speed of the user in the first resistance section. When the first walking speed is out of a first target speed range, the processor may perform at least one of an operation of adjusting the first resistance intensity level to determine a resistance intensity level of a second resistance section of the exercise program, an operation of adjusting the first target speed to determine a target speed of the second resistance section, or an operation of adjusting the first target time to determine a target time of the second resistance section.

[0305] According to one embodiment, the processor can determine a target speed of a first auxiliary section corresponding to a next section of the first resistance section based on the first target speed, determine a first assistance intensity level related to an assistance torque intensity in the first assistance section based on the target speed in the first assistance section, and determine a target time of the first assistance section based on the first target time.

[0306] In one embodiment, the processor may determine the target speed of the first auxiliary section by multiplying the first target speed by a ratio.

[0307] In one embodiment, the ratio may be based on the exercise program.

[0308] According to one embodiment, the processor may determine a target speed in a second assist section corresponding to a next section of the second resistance section based on the target speed of the second resistance section. When the second walking speed of the user in the first assist section exceeds a second target speed range, the processor may determine a second assist intensity level higher than the assist intensity level corresponding to the target speed of the second assist section as the assist intensity level of the second assist section. When the second walking speed is less than the second target speed range, the processor may determine a third assist intensity level lower than the assist intensity level corresponding to the target speed of the second assist section as the assist intensity level of the second assist section.

[0309] According to one embodiment, when the exercise program ends, the processor can determine the resistance intensity level and target speed of the starting resistance section of the exercise program based on the resistance intensity level and target speed of the last resistance section of the exercise program, respectively, and can determine the assistance intensity level and target speed of the starting assistance section of the exercise program based on the assistance intensity level and target speed of the last assistance section of the exercise program, respectively.

[0310] According to one embodiment, when the exercise program ends, the processor receives a response from the user regarding the exercise intensity of the exercise program, and adjusts at least one of the resistance intensity level of the starting resistance section, the target speed of the starting resistance section, or the assistance intensity level of the starting assistance section based on the received response.

[0311] According to one embodiment, the processor can adjust the first resistance intensity level when the first resistance intensity level does not correspond to a limit level and the first walking speed is outside the first target speed range, determine the adjusted first resistance intensity level as the resistance intensity level of the second resistance section, and determine the first target speed and the first target time as the target speed and target time of the second resistance section, respectively.

[0312] According to one embodiment, when the first resistance intensity level corresponds to a limit level and the first walking speed is outside a first target speed range, the processor may determine the first resistance intensity level as a resistance intensity level of the second resistance section, adjust the first target speed, determine the adjusted first target speed as the target speed of the second resistance section, and determine the first target time as the target time of the second resistance section.

[0313] According to one embodiment, when the first resistance intensity level corresponds to a limit level, the first target speed corresponds to a limit speed, and the first walking speed is outside the first target speed range, the processor may determine the first resistance intensity level as a resistance intensity level of the second resistance section, determine the first target speed as a target speed of the second resistance section, adjust the first target time, and determine the adjusted first target time as a target time of the second resistance section.

[0314] According to one embodiment, the wearable device may further include a communication circuit that forms a wireless communication connection with an external electronic device (e.g., a smartwatch (132)). The processor may receive heart rate information of the user from the external electronic device through the communication circuit in the first resistance section, and, when the heart rate information is within a first target heart rate range and the first walking speed exceeds the first target speed range, determine a resistance intensity level of the second resistance section to be higher than the first resistance intensity level. The processor may determine a resistance intensity level of the second resistance section to be lower than the first resistance intensity level when the heart rate information is less than the first target heart rate range and the first walking speed is less than the first target speed range.

[0315] In one embodiment, the processor may provide an exercise program in which an intensity level related to the magnitude of the torque provided to the user varies according to a pattern.

[0316] According to one embodiment, a wearable device (120, 200, 300, 300-1) may include a driving module (30) that provides torque to a user and a processing circuit, and a processor (310) that controls the driving module. The processor may control the driving module to provide assistive torque to the user in a first section (e.g., assistive section 1 (1210) of FIG. 12) of an exercise program (1200). The processor may determine whether a walking speed of the user in the first section is within a target speed range of the first section. If the walking speed is within the target speed range, the processor may determine the target speed of the first section as a target speed of a second section (e.g., assistive section 2 (1220) of FIG. 12) of the exercise program and maintain a basic assist intensity level set in the second section. The processor may determine the target speed of the second section by adjusting the target speed of the first section when the walking speed is outside the target speed range, and may determine the assist intensity level of the second section by adjusting the basic assist intensity level.
