[0030] Hereinafter, specific embodiments will be described in detail with reference to the attached drawings. In the description with reference to the attached drawings, identical components are assigned the same reference numerals regardless of the drawing numbers, and redundant descriptions thereof will be omitted.

[0031] FIG. 1 is a drawing for explaining an overview of a wearable device worn on a user's body according to various embodiments.

[0032] Referring to FIG. 1, in one embodiment, a wearable device (100) may be a device worn on a user's (110) body to assist the user's (110) walking, exercising, and / or working. The wearable device (100) may also be used to measure the user's (110) physical ability (e.g., walking ability, exercise ability, exercise posture). In a specific embodiment, the term 'wearable device' may be replaced with 'wearable robot', 'walking assistance device', or 'exercise assistance device'. The user (110) may be a person who wears the wearable device (100) and walks, exercises, or works.

[0033] In a specific embodiment, for convenience of explanation, a hip-type wearable device (100) as illustrated in FIG. 1 is used as an example, but the scope of the embodiment is not limited thereto. As described above, the wearable device (100) may also be worn on other body parts (e.g., upper arms, lower arms, hands, calves, or feet) other than the waist and thighs. The shape and configuration of the wearable device (100) may vary depending on the body part on which it is worn.

[0034] The wearable device (100) may include a support frame (e.g., a waist support frame (20) of FIG. 3) for supporting the body of the user (110) when the wearable device (100) is worn on the body of the user (110), a drive module (e.g., a first drive module (45) and a second drive module (35) of FIG. 3) for generating a torque applied to the legs of the user (110), a torque transmission frame (e.g., a first torque transmission frame (55) and a second torque transmission frame (50) of FIG. 3) for transmitting the torque generated by the drive module to the legs of the user (110), a sensor circuit including one or more sensors for obtaining sensor data including movement information about the body movement of the user (110) (e.g., leg movement, pelvic movement), a control circuit (e.g., a control circuit (510) of FIG. 5) for controlling the operation of the wearable device (100), and a battery for supplying power to each component of the wearable device (100).

[0035] In one embodiment, the sensor circuit of the wearable device (100) may include an angle sensor (e.g., the first angle sensor (524) and the second angle sensor (524-1) of FIG. 5) and an inertial sensor (e.g., the inertial sensor (522) of FIG. 5). The angle sensor may measure a rotational angle of the torque transmission frame of the wearable device (100) corresponding to the hip joint angle of the user (110). The angle sensor may include, for example, an encoder and / or a hall sensor. In one embodiment, the angle sensor may be positioned near a motor included in a drive module that is directly or indirectly connected to the torque transmission frame. The inertial sensor may include an accelerometer, a gyroscope, and a magnetometer, and may measure changes in acceleration and / or angular velocity according to the movement of the user (110). The inertial sensor can measure, for example, the movement of the lumbar support frame or base body (e.g., the base body (80) of FIG. 3) of the wearable device (100). The movement of the lumbar support frame or base body measured by the inertial sensor can correspond to the pelvic movement (or upper body movement) of the user (110).

[0036] In one embodiment, an inertial sensor, a control circuit, peripheral circuits (e.g., an audio output circuit, a communication circuit, a haptic circuit), and a battery may be disposed within a base body of a wearable device (100). The base body may be positioned at the waist area of ​​a user (110) while the user (110) is wearing the wearable device (100). The base body may be formed or attached to the outside of a waist support frame of the wearable device (100). The base body may support the lumbar region of the user (110).

[0037] A wearable device (100) may be worn on a user's (110) body (e.g., lower body (legs, ankles, knees, etc.) and / or upper body (torso, arms, wrists, etc.)) to apply external forces, such as assistance force and / or resistance force, to the body movements of the user (110). Assistance force refers to a force applied in the same direction as the body movement direction of the user (110), and represents a force that assists the body movements of the user (110). Resistance force refers to a force applied in the opposite direction to the body movement direction of the user (110), and represents a force that hinders the body movements of the user (110). The term 'resistance force' may also be referred to as 'exercise load'.

[0038] In one embodiment, the wearable device (100) may operate in a walking assistance mode to assist the walking of a user (110). In the walking assistance mode, the wearable device (100) may assist the walking of the user (110) by applying an assistive force generated from a driving module (including a motor) of the wearable device (100) to the body of the user (110). The wearable device (100) may assist the force required for the walking of the user (110), thereby enabling the user (110) to walk independently or to walk for a long time, thereby expanding the walking ability of the user (110). The wearable device (100) may also help improve the walking of a user with abnormal walking habits or walking posture.

[0039] In one embodiment, the wearable device (100) may operate in an exercise assistance mode to enhance the exercise effect of the user (110) or to provide various exercise experiences to the user (110). The exercise assistance mode may include a resistance mode and an assistance mode. The resistance mode of the exercise assistance mode refers to a mode that impedes the body movement of the user (110) or provides resistance to the body movement of the user (110) by applying a resistance force generated from a driving module to the body of the user (110). If the wearable device (100) is a hip-type wearable device worn on the waist (or pelvis) and legs (e.g., thighs) of the user (110), the wearable device (100) may provide an exercise load to the leg movement of the user (110) while being worn on the legs in the resistance mode, thereby further enhancing the exercise effect on the legs of the user (110). The assist mode of the exercise assistance mode refers to a mode in which an assistive force is applied to the body of the user (110) to assist the body movement of the user (110). In the assist mode, an assistive force, which is a force in the same direction as the body movement, is provided to the user (110). For example, when a disabled person or an elderly person wears a wearable device (100) and exercises, the wearable device (100) may provide an assistive force to assist the body movement. In the assistive mode, the wearable device (100) may provide a force in the same direction as the leg movement direction of the user (110), and the user (110) may perform an exercise with less force through the force provided from the wearable device (100). In an exercise program performed using the wearable device (100), the resistance mode and the assistive mode may be operated in combination. For example, the wearable device (100) may provide an assistive force and a resistance force in combination for each exercise section or time section, such as providing an assistive force in some exercise sections and a resistance force in other exercise sections.

[0040] In the exercise assistance mode, various exercise programs can be operated according to the exercise purpose and / or the physical ability of the user (110). The exercise program is exercise content performed by the user (110) using the wearable device (100), and may include, for example, aerobic exercise, strength training, postural balancing exercise, or any combination thereof. The type of exercise program is not limited thereto and may vary. Depending on the exercise program performed by the wearable device (100), the resistance mode and the assistance mode may be appropriately operated in an alternating manner, and a target exercise speed suitable for the physical condition (e.g., heart rate) of the user (110) while performing the exercise may be guided to the user.

[0041] In one embodiment, the wearable device (100) may operate in a physical ability measurement mode for measuring the physical ability of a user (110). The wearable device (100) may measure movement information of the user (110) using a sensor (e.g., an angle sensor, an inertial measurement unit (IMU)) provided in the wearable device (100) while the user (110) walks and / or exercises, and may evaluate the physical ability of the user (110) based on the measured movement information. Through the movement information of the user (110) measured by the wearable device (100), the gait index (e.g., number of steps, total walking distance, stride) and / or the exercise ability index (e.g., muscle strength, exercise endurance, postural balance) of the user (110) may be estimated.

[0042] FIG. 2 is a drawing for explaining an exercise assistance system according to various embodiments.

[0043] Referring to FIG. 2, the exercise assistance system (200) may include a wearable device (100), an electronic device (210), another wearable device (220), and a server (230). In the exercise assistance system (200), at least one of the devices other than the wearable device (100) (e.g., the electronic device (210), another wearable device (220), or the server (230)) may be omitted, or one or more other devices (e.g., a dedicated controller device for the wearable device (100)) may be added.

[0044] In one embodiment, the wearable device (100) may be worn on the user's body in a walking assistance mode to assist the user's movements. For example, the wearable device (100) may be worn on the user's leg to generate an assistive force to assist the user's leg movements, thereby assisting the user's walking.

[0045] In one embodiment, the wearable device (100) may generate and apply to the user's body a resistance force to hinder the user's body movement and / or an assistive force to assist the user's body movement in order to enhance the user's exercise effect in the exercise assistance mode. In the exercise assistance mode, the user may select an exercise program (e.g., aerobic exercise such as power walking and outdoor walking, strength training such as squats, split lunges, dumbbell squats, and lunge and knee ups, stretching, postural balancing exercise, or any combination thereof) and / or an exercise intensity to be applied to the exercise program via the electronic device (210). The wearable device (100) may control a driving module of the wearable device (100) according to the exercise program and / or exercise intensity selected by the user. For example, the wearable device (100) can adjust the strength of the resistance and / or assist force generated by the drive module according to the exercise intensity selected by the user. The wearable device (100) can control the drive module to generate a resistance force corresponding to the exercise intensity selected by the user. As the exercise intensity increases, the magnitude of the resistance force applied to the user can also increase.

[0046] In one embodiment, the wearable device (100) may be used to measure a user's physical ability (e.g., walking ability) in conjunction with an electronic device (210). The wearable device (100) may operate in a physical ability measurement mode, which is a mode for measuring the user's physical ability under the control of the electronic device (210), and may transmit sensor data including movement information of the wearable device (100) according to the user's body movement to the electronic device (210) in the physical ability measurement mode. The electronic device (210) may analyze the sensor data received from the wearable device (100) to evaluate the user's physical ability and provide the evaluation result to the user. Based on the evaluation result of the physical ability, the electronic device (210) may recommend an exercise program that may be beneficial to the user or provide a guide voice during exercise.

[0047] The wearable device (100) can transmit sensor data measured through an angle sensor and / or an inertial sensor and device information (e.g., charging status information, operation mode information, setting information) of the wearable device (100) to an electronic device (210) and / or a server (230), and can receive a control signal for controlling the operation of the wearable device (100) from the electronic device (210) and / or the server (230).

[0048] The electronic device (210) can communicate with the wearable device (100) via wireless communication (e.g., Bluetooth communication) or wired communication, and can remotely control the wearable device (100) or provide the user with status information about the status of the wearable device (100) (e.g., booting status, charging status, exercise program operation status, error status). The electronic device (210) can recommend an exercise program using the wearable device (100) to the user, and analyze an exercise performed by the user. The electronic device (210) can receive sensor data acquired by a sensor (e.g., an angle sensor, an inertial sensor) of the wearable device (100) from the wearable device (100), and can estimate the user's current exercise status, exercise result, exercise posture, and / or physical ability based on the received sensor data. The electronic device (210) can provide the user with the user's estimated current exercise status, exercise results, exercise posture, and / or physical ability through a graphical user interface (GUI).

[0049] In one embodiment, a user may execute a program (e.g., an application) on an electronic device (210) to control a wearable device (100), and the user may adjust the operation or setting values ​​(e.g., the torque intensity output from a motor of a driving module, the volume of audio output from an audio output circuit (e.g., the audio output circuit (550) of FIG. 5), and the brightness of a lighting module (e.g., the lighting module (85) of FIG. 3)) of the wearable device (100) through the program. The program executed on the electronic device (210) may provide a graphical user interface for interaction with the user. The electronic device (210) may be a variety of devices. For example, the electronic device (210) may include, but is not limited to, a portable communication device (e.g., a smartphone), a computer device, a portable multimedia device, or a home appliance device (e.g., a television, an audio device, a projector device).

[0050] According to one embodiment, the electronic device (210) may be connected to the server (230) using short-range wireless communication or cellular communication. The server (230) may receive user profile information of a user using the wearable device (100) from the electronic device (210), and store and manage the received user profile information. The user profile information may include, for example, information on at least one of name, age, gender, height, weight, medical history, or body mass index (BMI). The server (230) may receive exercise history information regarding exercise performed by the user from the electronic device (210), and store and manage the received exercise history information. The server (230) may provide the electronic device (210) with various exercise programs or physical ability measurement programs that may be provided to the user. In one embodiment, the server (230) may be connected to the wearable device (100). The server (230) can receive sensor data measured by the wearable device (100) from the wearable device (100) and transmit control signals and / or exercise program-related data for controlling the operation of the wearable device (100) to the wearable device (100). In one embodiment, the server (230) can be a cloud server.

[0051] In one embodiment, the wearable device (100) may provide (or output) feedback (e.g., visual feedback, auditory feedback, tactile feedback) corresponding to the state of the wearable device (100) according to a control signal received from the electronic device (210). For example, the wearable device (100) may provide visual feedback through a lighting unit (e.g., the lighting module (85) of FIG. 3) and may provide auditory feedback through an audio output circuit (e.g., the audio output circuit (550) of FIG. 5). The wearable device (100) may provide tactile feedback in the form of vibration to the user's body through a haptic circuit (e.g., the haptic circuit (560) of FIG. 5). The electronic device (210) may also provide (or output) feedback (e.g., visual feedback, auditory feedback, tactile feedback) corresponding to the state of the wearable device (100).

[0052] In one embodiment, the wearable device (100) and / or the electronic device (210) may perform exercise coaching functions in real time while the user is exercising, and may provide relevant information to the user through various feedback means. For example, the wearable device (100) and / or the electronic device (210) may output exercise coaching content to guide the user's exercise while the user is exercising while wearing the wearable device (100). The exercise coaching content may provide, for example, real-time guidance for improving the user's walking ability, guidance for changing exercise type / intensity, provision of exercise-related information, and auditory content (e.g., a guide voice) related to encouragement. The auditory content may be provided to the user through an audio output circuit of the wearable device (100) (e.g., audio output circuit (550)), an audio output circuit of the electronic device (210) (e.g., audio output circuit (750) of FIG. 7) and / or another wearable device (e.g., wireless earphones (222), smartwatch (224)) connected to the electronic device (210). In one embodiment, the exercise coaching content may include visual content (e.g., a guide screen) output through a display of the electronic device (210) and / or a display of another wearable device (e.g., smartwatch (224)).

[0053] According to one embodiment, the wearable device (100) and / or the electronic device (210) may be directly or indirectly connected to another wearable device (220). The user's exercise result information, physical ability information, and / or exercise motion evaluation information determined by the electronic device (210) may be transmitted to the other wearable device (220) and provided to the user through the other wearable device (220). Status information of the wearable device (100) may also be transmitted to the other wearable device (220) and provided to the user through the other wearable device (220). In one embodiment, the wearable device (100), the electronic device (210), and the other wearable device (220) may be connected to each other through wireless communication (e.g., Bluetooth communication, Wi-Fi communication). Other wearable devices (220) may be, for example, wireless earphones (222), a smartwatch (or a wearable device in the form of a watch) (224), or smartglasses (a wearable device in the form of glasses or goggles) (226), but are not limited to the aforementioned devices.

[0054] In one embodiment, the wireless earphones (222) may be wirelessly connected to the electronic device (210) and / or the wearable device (100) to output exercise coaching content, music, and / or sound effects related to an exercise program. The wireless earphones (222) may provide the user with, for example, a guide voice for providing information related to the exercise program (e.g., an introduction to the exercise program, remaining exercise time) and / or a guide voice for real-time exercise coaching. The wireless earphones (222) may include a microphone, and the microphone may receive a user's voice input. The voice input received through the microphone may be transmitted to the electronic device (210), and voice recognition may be performed on the voice input in the electronic device (210).

The electronic device (210) may estimate the heart rate information (e.g., current heart rate, maximum heart rate, average heart rate) and / or electromyography information of the user based on the biosignal received from the smartwatch (224), and may provide the estimated heart rate information and / or electromyography information to the user. In one embodiment, the smartwatch (224) may output a guide screen for guiding the user on exercise coaching and / or exercise performance methods when the user is exercising.

[0056] In one embodiment, the smartwatch (224) may include an inertial sensor for measuring user movement information and / or a position sensor for measuring user location information, and may transmit the user movement information and / or location information to the electronic device (210) and / or the wearable device (100). The smartwatch (224) may include a communication circuit (e.g., a short-range communication circuit) for communicating with another device (e.g., the electronic device (210), the wearable device (100)). In one embodiment, the smartwatch (224) may provide an exercise program related interface through a display. The exercise program related interface may be implemented through a separate application installed on the smartwatch (224). The user may also control the wearable device (100) through the smartwatch (224).

[0057] In one embodiment, the smart glasses (226) may provide information to the user through a display in the form of glasses. For example, the smart glasses (226) may output information such as current exercise speed, target exercise speed, current exercise volume achieved, exercise execution time, and / or biometric information through the display during the execution of an exercise program.

The sensor circuit may include one or more sensors that acquire sensor data including movement information of the user and / or movement information of components of the wearable device (100). For example, the one or more sensors may include, but are not limited to, an inertial sensor (e.g., an inertial sensor (522) of FIG. 5) for measuring movement of the user's pelvis or movement of the lumbar support frame (20)) and / or an angle sensor (e.g., a first angle sensor (524) and a second angle sensor (524-1) of FIG. 5) for measuring an angle of the user's hip joint or a torque transmission frame (e.g., a first torque transmission frame (55) and a second torque transmission frame (50)). The angular velocity of the user's hip joint or the angular velocity of the torque transmission frame may be determined by differentiating the angle of the user's hip joint or the angle of the torque transmission frame measured by the angle sensor.

[0065] In one embodiment, the one or more sensors may further include at least one of a position sensor, a torque sensor, a pressure sensor, a temperature sensor, a biosignal sensor (e.g., a heart rate sensor, an electrocardiogram sensor), a distance sensor, a barometric pressure sensor, or a proximity sensor.

[0067] The first driving module (45) and the second driving module (35) can generate an external force (or torque) applied to the user's body based on a control signal generated by the processor. For example, the first driving module (45) and the second driving module (35) can generate an assistive force or a resistance force applied to the user's leg. In one embodiment, the first driving module (45) can be positioned corresponding to the user's right hip joint position, and the second driving module (35) can be positioned corresponding to the user's left hip joint position. The first driving module (45) can generate a torque to move (or rotate) the first torque transmission frame (55) in the forward or backward direction of the wearable device (100). The second driving module (35) can generate a torque to move (or rotate) the second torque transmission frame (50) in the forward or backward direction of the wearable device (100).

The first actuator may provide power transmitted to the first joint member, and the second actuator may provide power transmitted to the second joint member. The first actuator and the second actuator may each include a motor that receives power from a battery and generates power (or torque). When the motor is supplied with power and driven, the motor may generate a force (assisting force) to assist the user's body movement or a force (resisting force) to impede the body movement. In one embodiment, the processor may control the intensity and direction of the force generated by the motor by controlling the voltage and / or current supplied to the motor.

[0069] In one embodiment, the first joint member and the second joint member can receive power from the first actuator and the second actuator, respectively, and apply an external force to the user's body based on the received power. The first joint member and the second joint member can be disposed at positions corresponding to the user's joints, respectively. One side of the first joint member can be directly or indirectly connected to the first actuator, and the other side can be directly or indirectly connected to the first torque transmission frame (55). The first joint member can be rotated by the power received from the first actuator. An encoder or a hall sensor that can act as an angle sensor for measuring a rotation angle of the first joint member or the first torque transmission frame (55) (corresponding to the user's joint angle) can be disposed on one side of the first joint member. One side of the second joint member can be connected to the second actuator, and the other side can be connected to the second torque transmission frame (50). The second joint member can be rotated by power transmitted from the second actuator. An encoder or hall sensor that can function as an angle sensor for measuring the rotation angle of the second joint member or the second torque transmission frame (50) can also be arranged on one side of the second joint member.

[0070] In one embodiment, the first actuator may be disposed laterally of the first joint member, and the second actuator may be disposed laterally of the second joint member. The rotational axis of the first actuator and the rotational axis of the first joint member may be disposed to be spaced apart from each other, and the rotational axis of the second actuator and the rotational axis of the second joint member may also be disposed to be spaced apart from each other. However, the present invention is not limited thereto, and the actuator and the joint member may share a rotational axis. In one embodiment, each actuator may be disposed to be spaced apart from the joint member. In this case, each of the first drive module (45) and the second drive module (35) may further include a power transmission module (not shown) that transmits power from the actuator to the joint member. The power transmission module may be a rotating body such as a gear, or a longitudinal member such as a wire, a cable, a string, a spring, a belt, or a chain. However, the scope of the embodiment is not limited by the positional relationship between the actuator and joint member and the power transmission structure described above.

[0071] In one embodiment, the first torque transmission frame (55) and the second torque transmission frame (50) can transmit the torque generated by the first driving module (45) and the second driving module (35) to the user's body (e.g., the leg) when the wearable device (100) is worn on the user's leg. The transmitted torque can act as an external force applied to the movement of the user's leg. One end of each of the first torque transmission frame (55) and the second torque transmission frame (50) can be directly or indirectly connected to a joint member and rotated. The other end of each of the first torque transmission frame (55) and the second torque transmission frame (50) is directly or indirectly connected to the first thigh fastening portion (2) and the second thigh fastening portion (1), so that the first torque transmission frame (55) and the second torque transmission frame (50) can support the user's thigh while transmitting the torque generated by the first driving module (45) and the second driving module (35) to the user's thigh. For example, the first torque transmission frame (55) and the second torque transmission frame (50) can push or pull the user's thigh. The first torque transmission frame (55) and the second torque transmission frame (50) can extend along the length of the user's thigh and can be bent to wrap at least a portion of the user's thigh circumference. The first torque transmission frame (55) can be a torque transmission frame for transmitting torque to the user's right leg, and the second torque transmission frame (50) can be a torque transmission frame for transmitting torque to the user's left leg.

[0072] The first thigh fastening part (2) and the second thigh fastening part (1) are directly or indirectly connected to the first torque transmission frame (55) and the second torque transmission frame (50), respectively, and can fasten the wearable device (100) to the user's leg (particularly, the thigh).

The first cover and the second cover may apply torque generated from the first driving module (45) and the second driving module (35) to the user's thigh, respectively. The first cover and the second cover may be disposed on one side of the user's thigh, respectively, to push or pull the user's thigh. The first cover and the second cover may be disposed along the circumferential direction of the user's thigh. The first cover and the second cover may extend in both directions with respect to the other end of the first torque transmission frame (55) and the second torque transmission frame (50), respectively, and may include a curved surface corresponding to the user's thigh. One end of each of the first cover and the second cover may be directly or indirectly connected to the first fastening frame and the second fastening frame, respectively. The other end of each of the first cover and the second cover can be directly or indirectly connected to the first strap and the second strap.

[0074] The first fastening frame and the second fastening frame may be arranged to, for example, surround at least a portion of the user's thigh, thereby preventing the user's thigh from being detached from the wearable device (100) or reducing the possibility of detachment. The first fastening frame may have a fastening structure connecting the first cover and the first strap, and the second fastening frame may have a fastening structure connecting the second cover and the second strap.

[0075] The first strap may encircle the user's right thigh, the remaining portion not covered by the first cover and the first fastening frame, and the second strap may encircle the user's left thigh, the remaining portion not covered by the second cover and the second fastening frame. The first strap and the second strap may comprise, for example, an elastic material (e.g., a band).

Each of these sensors may be present in multiples, and some may be omitted.

[0080] The inertial sensor (522) can measure the movement of the user's body. The inertial sensor (522) can sense the acceleration, angular velocity, and rotation angle (e.g., roll, pitch, yaw) of the X-axis, Y-axis, and Z-axis according to the user's movement. The inertial sensor (522) can measure, for example, the movement of the user's pelvis. The inertial sensor (522) can measure the anteroposterior tilt (tilt) for the anteroposterior tilt of the user's pelvis, the lateral oblique (oblique) for the left-right tilt of the pelvis, and the rotation of the pelvis. The roll, pitch, and yaw measured by the inertial sensor (522) may each correspond to any one of the anteroposterior tilt, lateral oblique, and rotation of the pelvis. The user's pelvic movement may correspond to the movement of the lumbar support frame (e.g., the lumbar support frame (20) of FIG. 3) of the wearable device (100). In one embodiment, the inertial sensor (522) may be located on a printed circuit board within the base body of the wearable device (100) (e.g., the base body (80) of FIG. 3) and may measure a tilt indicating a degree of inclination of the wearable device (100) and / or a change in direction of the wearable device (100).

[0081] In one embodiment, the first angle sensor (524) and the second angle sensor (524-1) can measure the hip joint angle according to the movement of the user's leg. The first angle sensor (524) can sense the hip joint angle of the user's right leg, and the second angle sensor (524-1) can sense the hip joint angle of the user's left leg. Each of the first angle sensor (524) and the second angle sensor (524-1) can include, for example, an encoder and / or a hall sensor. The hip joint angle of the right leg sensed by the first angle sensor (524) may correspond to the movement (e.g., angle) of the first torque transmission frame (e.g., the first torque transmission frame (55) of FIG. 3) of the wearable device, and the hip joint angle of the left leg sensed by the second angle sensor (524-1) may correspond to the movement (e.g., angle) of the second torque transmission frame (e.g., the second torque transmission frame (50) of FIG. 3) of the wearable device.

[0082] In one embodiment, the first angle sensor (524) and the second angle sensor (524-1) may be angle sensors that sense the knee joint angle or the ankle joint angle according to the user's leg movement.

[0084] In one embodiment, the one or more sensors may further include a torque sensor for sensing a torque value, a position sensor for obtaining a position value of the wearable device (100), a proximity sensor for detecting the proximity of an object, a biosignal sensor for detecting a biosignal of a user, a distance sensor for measuring a distance to an object, a pressure sensor for measuring a pressure value, and / or a temperature sensor for measuring an ambient temperature.

[0085] The input circuit (540) may receive instructions or data to be used in a component of the wearable device (100) (e.g., a processor (512)) from an external source (e.g., a user) of the wearable device (100). The input circuit (540) may include, for example, a key (e.g., a button) and / or a touch screen.

[0086] The audio output circuit (550) can output audio signals to the outside of the wearable device (100). The audio output circuit (550) can include a speaker that outputs guide audio signals (e.g., driving start sound, operation error notification sound), music content, and / or auditory exercise coaching content (e.g., guide voice).

[0087] The drive module (530, 530-1) can generate an external force applied to the user's leg under the control of the control circuit (510). The drive module (530, 530-1) is located at a location corresponding to the user's hip joint position and can generate a torque applied to the user's leg based on a control signal generated by the control circuit (510). The control circuit (510) can transmit the control signal to the motor driver circuit (532, 532-1), and the motor driver circuit (532, 532-1) can control the operation of the motor (534, 534-1) by generating a current signal (or voltage signal) corresponding to the control signal and supplying it to the motor (534, 534-1). Depending on the control signal, the current signal may not be supplied to the motor (534, 534-1). The motor driver circuit (532, 532-1) can convert the direct current (DC) voltage supplied from the battery into an alternating current (AC) voltage and supply it to the motor (534, 534-1). One or more motors (e.g., motor (534), motor (534-1)) included in the wearable device (100) can generate torque under the control of the processor (512). When the motor (534, 534-1) is driven by supplying a current signal to the motor (534, 534-1), the motor can generate an assistive force that assists the user's leg movement or a resistive force that hinders the leg movement. The motor (534; 534-1) can generate torque based on the electric energy supplied from the battery. The motor (534; 534-1) can be, for example, a brushless DC (BLDC) motor or a permanent magnet synchronous motor (PMSM).

[0095] A wearable device (100) according to one embodiment may provide a workout coaching function that provides workout coaching content according to the user's workout performance status while the user wears the wearable device (100) and performs an exercise. This workout coaching function may be provided under the control of an electronic device (210) through cooperation with the electronic device (210), or may be provided under the control of the wearable device (100).

[0096] When the voice coaching function is provided under the control of the electronic device (210), the wearable device (100) transmits sensor data and / or exercise data (e.g., stride, walking time, number of steps) determined by the processor (512) based on the sensor data to the electronic device (210) through the communication circuit (516), and the electronic device (210) can control the exercise coaching function based on the data received from the wearable device (100). An embodiment in which the voice coaching function is provided under the control of the electronic device (210) is described in more detail below.

[0097] When a voice coaching function is provided under the control of the wearable device (100), one or more sensors (e.g., an inertial sensor (522), a first angle sensor (524), a second angle sensor (524-1)) of the wearable device (100) can obtain sensor data including movement information of the wearable device (100) by measuring the movement of the wearable device (100) corresponding to the movement of a user wearing the wearable device (100). The memory (514) can store computer-executable instructions, and the computer-executable instructions, when individually or collectively executed by one or more processors (512), can cause the wearable device (100) to perform the voice coaching function.

[0099] In one embodiment, one or more processors (512) may determine a user's performance for a first exercise target index specified in exercise program information based on sensor data acquired by one or more sensors, and control first exercise coaching content for the first exercise target index to be output based on the determined performance for the first exercise target index. For example, if the first exercise target index is walking speed, the user's walking speed measured in real time based on the sensor data may be determined as the user's performance for the first exercise target index, and exercise coaching for the walking speed may be performed. When the number of times the first exercise coaching content of the same comment is output reaches a threshold number, the one or more processors (512) may change the output cycle of the first exercise coaching content or change the target condition for the first exercise target index. When it is determined that the determined performance satisfies the target condition set for the first exercise target index, one or more processors (512) can determine the user's performance for a second exercise target index that is specified in the exercise program information and has a lower priority than the first exercise target index, and control second exercise coaching content for the second exercise target index to be output based on the determined performance for the second exercise target index. For example, when the user's performance for the determined walking speed during the exercise satisfies the target condition (e.g., maintaining a walking speed higher than the target walking speed for a set period of time), the user's performance for the stride can be determined, and exercise coaching for the stride can be performed. When the number of times the second exercise coaching content of the same comment is output reaches a threshold number, one or more processors (512) can change the output cycle of the second exercise coaching content or change the target condition for the second exercise target index.The first exercise target index and the second exercise target index may be, for example, any one of walking speed, stride length, walking symmetry index, heart rate, number of steps, hip joint angle, moving distance, exercise time, and calorie consumption, and the first exercise target index and the second exercise target index may be different from each other. The exercise program performed by the user may define multiple exercise target indexes and priorities among the exercise target indexes. In addition to the operations described above, one or more processors (512) may perform operations of exercise coaching described in the present disclosure (e.g., operations related to exercise coaching performed by the electronic device (210).

By executing the application, a screen of a user interface (UI) for controlling the operation of the wearable device (100) or determining the operation mode of the wearable device (100) may be displayed on the display (212) of the electronic device (210). The UI may be, for example, a graphical user interface (GUI).

[0103] In one embodiment, the electronic device (210) may display a user interface (UI) screen on the display (212) for controlling the operation of the wearable device (100) or for performing an exercise program. The user may input a command (e.g., a command to execute a walking assistance mode or an exercise assistance mode) for controlling the operation of the wearable device (100) through the GUI screen on the display (212) of the electronic device (210) or select an exercise program to be performed through the wearable device (100). In addition, the user may input user information or set an exercise goal through the GUI screen. The user may change the settings of the wearable device (100) through the GUI screen (e.g., a torque parameter, sound / lighting). The electronic device (210) may generate a control command (or control signal) corresponding to a motion control command or a setting change command input by the user and transmit the generated control command to the wearable device (100). The wearable device (100) can operate according to the received control command, and transmit a control result and / or data (e.g., sensor data, result data processed by the wearable device (100)) according to the control command to the electronic device (210). The electronic device (210) can provide information (e.g., current exercise status information, exercise result information, exercise coaching content) based on the control result and / or data received from the wearable device (100) to the user through the display (212).

[0104] In one embodiment, the wearable device (100) and the electronic device (210) may perform an exercise coaching function in real time while the user is exercising through an exercise program. Through the exercise coaching function, exercise-related information may be provided to the user or exercise coaching content may be provided to the user to encourage the user's exercise performance. When the exercise coaching function is performed under the control of the electronic device (210), the wearable device (100) may transmit sensor data acquired by one or more sensors (e.g., the inertial sensor (522), the first angle sensor (524), and the second angle sensor (524-1) of FIG. 5 ) to the electronic device (210), and the electronic device (210) may determine exercise coaching content to be provided to the user based on the sensor data received from the wearable device (100). The electronic device (210) may determine the user's current exercise performance status based on the sensor data and information about the exercise program being performed by the user, select exercise coaching content appropriate for the user's current exercise performance status, and provide the selected exercise coaching content to the user. As previously described, the exercise coaching function may be performed under the control of the wearable device (100), in which case the wearable device (100) may determine exercise coaching content to be provided to the user based on acquired sensor data. The wearable device (100) may then provide the determined exercise coaching content to the user.

[0105] FIG. 7 is a diagram illustrating configurations of an electronic device according to various embodiments.

[0106] Referring to FIG. 7, the electronic device (210) may include a processor (710), a memory (720), a communication circuit (730), a display circuit (740), an audio output circuit (750), and an input circuit (760). In one embodiment, the electronic device (210) may omit at least one of these components (e.g., an audio output circuit (750)), or may have one or more other components added (e.g., a sensor circuit, a haptic circuit, a battery).

[0107] The processor (710) may control at least one other component (e.g., hardware or software component) of the electronic device (210) and perform various data processing or calculations. According to one embodiment, as at least a part of the data processing or calculation, the processor (710) may store a command or data received from another component (e.g., communication circuit (730)) in the memory (720), process the command or data stored in the memory (720), and store the resulting data in the memory (720). The processor (710) may include one or more processors, and the operations of the electronic device (210) described in the present disclosure may be performed by one processor or by a combination of multiple processors.

[0108] According to one embodiment, the processor (710) may include at least one of a main processor (e.g., a central processing unit or an application processor) or an auxiliary processor (e.g., a graphics processing unit, a neural network processing unit (NPU), an image signal processor, a sensor hub processor, or a communication processor) that can operate independently or in conjunction with the main processor. The processor (710) may also be implemented as a system on a chip (SoC) or an integrated circuit that performs processing.

[0109] The memory (720) can store various data used by at least one component (e.g., the processor (710) or the communication circuit (730)) of the electronic device (210). The data can include, for example, input data or output data for a program (e.g., an application) and commands related thereto. In one embodiment, the memory (514) can store user information (e.g., age, gender, exercise goal, BMI) about the user, sensor data received from the wearable device (100), and information about an exercise program. The memory (720) can include at least one computer-executable instruction. The memory (720) can include one or more memories, and instructions for controlling the processor (710) to perform operations of the electronic device (210) described in the present disclosure can be stored in one memory or can be divided and stored in multiple memories. The memory (720) can include a volatile memory or a non-volatile memory.

[0110] The communication circuit (730) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device (210) and another electronic device (e.g., wearable device (100), another wearable device (220), server (230)), and the performance of communication through the established communication channel. The communication circuit (730) may include a communication circuit for performing a communication function. The communication circuit (730) may operate independently from the processor (710) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication circuit (730) may include a wireless communication circuit (e.g., a Bluetooth communication circuit, a cellular communication circuit, a Wi-Fi communication circuit, or a GNSS communication circuit) that performs wireless communication, or a wired communication circuit (e.g., a LAN communication circuit, or a power line communication circuit). The communication circuit (730) may, for example, transmit a control command to the wearable device (100) and receive at least one of sensor data including body movement information of a user wearing the wearable device (100), status data of the wearable device (100), or control result data corresponding to the control command from the wearable device (100).

[0111] The display circuit (740) can visually provide information to an external device (e.g., a user) of the electronic device (210). The display circuit (740) can include a display, such as, for example, an LCD or OLED display, a holographic device, or a projector device. The display circuit (740) can further include a control circuit for controlling display operation. In one embodiment, the display circuit (740) can further include a touch sensor configured to detect a touch, or a pressure sensor configured to measure the intensity of a force generated by a touch. The display circuit (740) can output a user interface screen for controlling the wearable device (100) or providing various information (e.g., information on an exercise program, setting information of the wearable device (100). The display circuit (740) can, for example, provide visual exercise coaching content to the user through the user interface screen.

[0112] The audio output circuit (750) can output an audio signal to the outside of the electronic device (210). The audio output circuit (750) can include a speaker that plays a guide audio signal (e.g., a driving start sound, an operation error notification sound), music content, or auditory exercise coaching content (e.g., a guide voice) based on the status of the wearable device (100). The audio output circuit (750) can output exercise coaching content.

[0113] The input circuit (760) can receive commands or data to be used in a component of the electronic device (210) (e.g., a processor (710)) from an external source (e.g., a user) of the electronic device (210). The input circuit (760) can include an input component circuit and can receive user input. The input circuit (760) can include, for example, a key (e.g., a button) and / or a touch recognition circuit for recognizing a touch on a screen.

[0114] In one embodiment, a user who wears a wearable device (100) and wishes to exercise may command the electronic device (210) to execute an exercise program through a user input. The electronic device (210) may display recommended exercise programs to the user through a display of the display circuit (740) and receive a user selection input for any one of the recommended exercise programs through the input circuit (760). In response to receiving the user selection input, the electronic device (210) may transmit a control signal for executing the selected exercise program to the wearable device (100) through the communication circuit (730). When the wearable device (100) receives the control signal for executing a specific exercise program from the electronic device (210), the wearable device (100) may execute the exercise program and sense the movement of the wearable device corresponding to the user's body movement through one or more sensors. The wearable device (100) may generate an assistive force and / or a resistive force through a motor according to the exercise program being executed. The communication circuit (730) can receive sensor data sensed by one or more sensors of the wearable device (100). The sensor data can include movement information about the movement of the wearable device (100) corresponding to the body movement of the user. The sensor data can include, for example, a movement value measured by an inertial sensor (e.g., an inertial sensor (522) of FIG. 5) of the wearable device (100) and an angle value measured by an angle sensor (e.g., a first angle sensor (524) and a second angle sensor (524-1) of FIG. 5). The movement value measured by the inertial sensor can include information about the waist movement or pelvic movement of the user, and the angle value measured by the angle sensor can include information about the leg movement of the user.

[0115] In one embodiment, the electronic device (210) may provide an exercise coaching function while the user is wearing the wearable device (100) and exercising using an exercise program. The exercise coaching function may refer to providing exercise-related information to the user based on the user's exercise performance status and / or the user's physical condition (e.g., heart rate), or providing auditory and / or visual feedback to encourage exercise performance. For example, the electronic device (210) may provide the user with exercise coaching content related to real-time guidance for improving the user's exercise effect, changing the exercise type / intensity, providing guidance, information, encouragement, or praise.

[0116] In one embodiment, the communication circuit (730) may receive sensor data measured by one or more sensors (e.g., the inertial sensor (522), the first angle sensor (524), and the second angle sensor (524-1) of FIG. 5) of the wearable device (100) worn on the user's body. The memory (720) may store computer-executable instructions. When the computer-executable instructions are individually or collectively executed by one or more processors (710), the computer-executable instructions may cause the electronic device (210) to perform operations of the voice coaching function of the electronic device (210) described in the present disclosure. For example, the one or more processors (710) may control exercise coaching content to be output based on exercise program information and received sensor data of the exercise program during execution of an exercise program using the wearable device (100). When the exercise coaching content is auditory exercise coaching content, one or more processors (710) can control the exercise coaching content to be output through at least one of an audio output circuit (750), a wearable device (100), and wireless earphones (e.g., wireless earphones (222) of FIG. 2) connected to the electronic device (210). When the exercise coaching content is visual exercise coaching content, one or more processors (710) can control the exercise coaching content to be output through at least one of a display circuit (740), a smartwatch (e.g., a smartwatch (224) of FIG. 2), and smartglasses (e.g., a smartglass (226) of FIG. 2). The exercise coaching content can include periodic coaching content, immediate coaching content, tendency coaching content, progress coaching content, and motivational coaching content as described above.

[0117] In one embodiment, one or more processors (710) may determine a user's performance for a first exercise target indicator specified in exercise program information based on sensor data received from a wearable device (100), and control first exercise coaching content for the first exercise target indicator to be output based on the determined performance for the first exercise target indicator.

[0118] In one embodiment, the first exercise coaching content may include periodic coaching content including guidance comments regarding at least one of a first exercise target metric and the user's current performance determined for the first exercise target metric. The periodic coaching content may be output at a time period determined in the exercise program information. For example, guidance comments for guiding the user's current exercise status and / or target condition may be output as periodic coaching content at a period of n (natural number) seconds for the first exercise target metric. If it is determined that the user is performing well on the first exercise target metric (e.g., if the current performance on the first exercise target metric satisfies the target condition), one or more processors (710) may control motivational coaching content to be output to motivate the user's exercise performance (e.g., praise, encouragement) between the time points at which the periodic coaching content is output. If it is determined that the user is performing well on the first exercise target metric for the determined time period, one or more processors (710) may control periodic coaching content for a second exercise target metric with a lower priority to be provided to the user. The periodic coaching content for the second exercise target metric may include guidance comments regarding at least one of the second exercise target metric and the user's current performance determined for the second exercise target metric. If it is determined that the user is not performing well on the first exercise target metric (e.g., the current performance on the first exercise target metric does not satisfy the target condition), one or more processors (710) may control the output of motivational coaching content to improve the user's exercise performance by pointing out the user's exercise performance between the output points of the periodic coaching content.

[0119] In one embodiment, an exercise program may include a first exercise session and a second exercise session following the first exercise session, and one or more processors (710) may reduce (e.g., change from 30 seconds to 20 seconds) the time period during which periodic coaching content is output in the second exercise session if the user's performance for a first exercise target metric determined in the first exercise session does not satisfy a target condition set for the first exercise session. For example, if the ratio of time during which the performance for the first exercise target metric satisfies a target range is less than 60% of the total time of the first exercise session, the target condition set for the first exercise session may be determined to not be satisfied. As the time period during which periodic coaching content is output is reduced, periodic coaching content may be output more frequently in the second exercise session than in the first exercise session. If the target condition set for the first exercise session is determined to be satisfied, the time period during which periodic coaching content is output may be maintained as is in the second exercise session. In this way, the period of exercise coaching may be flexibly adjusted depending on the user's exercise performance status.

[0120] In one embodiment, the first exercise coaching content may include immediate coaching content including a guidance comment to notify that there is a significant change in performance for the first exercise target metric. The immediate coaching content may be output, for example, when the change in performance for the first exercise target metric over a time period is greater than a threshold. When the average value of the performance for the first exercise target metric over a time period changes rapidly, one or more processors (710) may control the output of immediate coaching content that may include a guidance comment to notify the user of the rapid change in performance and warn the user or to encourage the user to improve performance. For example, when the change in performance for the first exercise target metric over n (a natural number) seconds is greater than 20% of the previous performance, the immediate coaching content to notify that there is a significant change in performance may be output.

[0121] In one embodiment, the first exercise coaching content may include tendency coaching content that includes comments to motivate the user's exercise performance when the performance for the first exercise goal metric measured over a predetermined time period is within a target range. The tendency coaching content may be output whenever the predetermined time period is reached. The tendency coaching content may include guidance comments to inform the user of the first exercise goal metric and the results of a tendency analysis for the user's exercise when the performance for the first exercise goal metric measured over the predetermined time period is not within the target range. For example, when the average value of the performance for the first exercise goal metric over n (natural number) minutes satisfies the predetermined target range, one or more processors (710) may control the output of tendency coaching content that may include comments to praise the user's exercise performance. If the average value of the performance for the first exercise target indicator for n minutes exceeds or falls short of a predetermined target range, one or more processors (710) can control the output of trend coaching content that can include guidance comments for notifying the first exercise target indicator and the user's exercise trend analysis results.

[0122] In one embodiment, the first exercise coaching content may include progress coaching content that includes guidance comments to provide progress information regarding the performance of an exercise program. The progress coaching content may be output when the progress of the exercise program satisfies a set condition. The progress coaching content may be provided to the user at, for example, but not limited to, the start of an exercise, when the exercise progress reaches 50% of the total planned exercise section, and when the exercise ends. One or more processors (710) may control the provision of progress coaching content that may include guidance comments regarding the amount of exercise performed and the amount of exercise remaining in the exercise program when the exercise program has progressed N (a natural number)%. When the progress coaching content is provided, additional information, such as calories burned during the exercise, may be provided in addition to the progress information.

[0123] In one embodiment, the first exercise coaching content may include motivational coaching content that includes comments to motivate the user's exercise performance. The motivational coaching content may include comments of empathy, praise, or encouragement for the user's completion of the exercise performance by assessing the user's exercise performance status. The motivational coaching content may be output, for example, when the change in performance for the first exercise goal indicator during a one-hour period is greater than a threshold. If the change in performance for the first exercise goal indicator is greater than the threshold and the exercise goal of the exercise program corresponds to the exercise goal set by the user, motivational coaching content to praise the user's exercise performance may be output. In some embodiments, motivational coaching content may be output to encourage the user to continue exercising even when the exercise goal of the exercise program does not correspond to the exercise goal set by the user. Alternatively, the motivational coaching content may be output when the user enters a predefined exercise period with a defined performance level or when the performance for the first exercise goal indicator continues to fall short of the target condition.

[0124] In one embodiment, when the number of times the first exercise coaching content with the same comment is output reaches a threshold number, one or more processors (710) may change the output cycle of the first exercise coaching content or change the target condition for the first exercise goal indicator. For example, the output cycle of the first exercise coaching content may be shortened or the target condition for the first exercise goal indicator may be lowered.

[0125] In one embodiment, when output conditions of at least two types of exercise coaching contents among multiple types of exercise coaching contents are simultaneously satisfied, one or more processors (710) may control only the exercise coaching contents with the highest priority among the at least two types of exercise coaching contents whose output conditions are simultaneously satisfied to be output. The priorities may be predefined among periodic coaching contents, instantaneous coaching contents, tendency coaching contents, progress coaching contents, and motivational coaching contents, and when the output conditions of at least two types of exercise coaching contents are simultaneously satisfied, the exercise content with the highest priority may be determined to be output. For example, when the output conditions of periodic coaching contents and instantaneous coaching contents are simultaneously satisfied, the instantaneous coaching contents with a higher priority may be output, and the periodic coaching contents may be omitted or their output period may be changed. When the output condition of another exercise coaching content is satisfied while one exercise coaching content is being output, one or more processors (710) may control the other exercise coaching contents not to be output. For example, if the output condition of the tendency coaching content is satisfied while the immediate coaching content is being output, the tendency coaching content may not be output.

[0126] In one embodiment, one or more processors (710) may perform exercise coaching centered on a second exercise target index based on a determination that the determined performance satisfies a target condition set for a first exercise target index. For example, if the performance for walking speed determined during the user's exercise satisfies a target condition (e.g., a walking speed of 3 minutes or more is a threshold value), the user's performance for stride length may be determined, and exercise coaching for stride length may be performed. The first exercise target index and the second exercise target index may be any one of, for example, walking speed, stride length, walking symmetry index, heart rate, number of steps, hip joint angle, distance traveled, exercise time, and calorie consumption, and the first exercise target index and the second exercise target index may be different from each other. The first exercise target index may correspond to a main exercise target index specified in an exercise program, and the second exercise target index may correspond to a sub-exercise target index. There may be one or more sub-exercise target indices.

[0127] If it is determined that the determined performance satisfies the target condition set for the first exercise target indicator, one or more processors (710) may determine the user's performance for a second exercise target indicator that is specified in the exercise program information and has a lower priority than the first exercise target indicator, and control second exercise coaching content for the second exercise target indicator to be output based on the determined performance for the second exercise target indicator. Similar to the first exercise coaching content, the second exercise coaching content may also include periodic coaching content, immediate coaching content, tendency coaching content, progress coaching content, and motivational coaching content. Depending on whether the output condition is satisfied, any one of the periodic coaching content, immediate coaching content, tendency coaching content, progress coaching content, or motivational coaching content may be output as the second exercise coaching content.

[0128] In one embodiment, when selecting a second exercise target index for which exercise coaching is to be performed following the first exercise target index, the one or more processors (710) may select a second candidate exercise target index with the highest priority among a plurality of second candidate exercise target indexes specified in exercise program information as the second exercise target index. The one or more processors (710) may determine the user's performance level for the selected second exercise target index. Alternatively, the one or more processors (710) may select a second candidate exercise target index with the lowest performance level among a plurality of second candidate exercise target indexes specified in exercise program information as the second exercise target index, and determine the user's performance level for the selected second exercise target index.

[0129] In one embodiment, when the number of times the second exercise coaching content with the same comment is output reaches a threshold number, one or more processors (710) may change the output cycle of the second exercise coaching content or change the target condition for the second exercise goal indicator. For example, the output cycle of the second exercise coaching content may be shortened or the target condition for the second exercise goal indicator may be lowered.

[0130] In one embodiment, the output condition of at least one of the first exercise coaching content or the second exercise coaching content may be determined based on user information defined for the user (e.g., gender, age, exercise goal, BMI). The electronic device (210) may provide exercise coaching content that takes into account the individual characteristics of the user based on the user information, thereby providing a personalized exercise coaching function for each user. In one embodiment, the output condition of the exercise coaching content may vary depending on the user information. For example, if the user is 60 years of age or older, the electronic device (210) may increase the output cycle of the periodic coaching content and the tendency coaching content from an initial value, and adjust the threshold for determining the output time of the instantaneous coaching content to a value smaller than the initial value. In this way, the output condition of each exercise coaching content may be adjusted based on the user characteristics defined by the user information.

[0131] In one embodiment, one or more processors (710) may perform exercise coaching centered on a third exercise target indicator if the performance determined for the second exercise target indicator satisfies the target condition set for the second exercise target indicator. The third exercise target indicator is different from the first exercise target indicator and the second exercise target indicator and may be predefined in the exercise program information.

[0132] In one embodiment, the one or more processors (710) may perform exercise coaching for the second exercise target indicator, and if it is determined that the performance for the first exercise target indicator is low, the exercise coaching for the second exercise target indicator may be stopped and exercise coaching for the first exercise target indicator may be started again. After the one or more processors (710) perform an operation of controlling the output of the second exercise coaching content, based on a determination that the user's performance for the first exercise target indicator does not satisfy the target condition, the one or more processors (710) may control the output of the first exercise coaching content for the first exercise target indicator based on the performance for the first exercise target indicator.

[0133] FIGS. 8A and 8B are drawings illustrating examples of providing exercise coaching content according to various embodiments.

[0134] Referring to FIGS. 8A and 8B , when a user wears the wearable device (100) and performs an exercise program, the wearable device (100) and / or the electronic device (210) may provide a real-time exercise coaching function to the user. The wearable device (100) may transmit sensor data measuring the user's movement while the user is performing the exercise program to the electronic device (210) in real time, and the electronic device (210) may measure exercise target indices specified for the exercise program currently being performed by the user based on the sensor data received from the wearable device (100). In some embodiments, the measurement of exercise target indices may be performed by the wearable device (100).

[0135] FIG. 8A is a diagram illustrating an example of outputting auditory exercise coaching content (810). A voice coaching function can be implemented through the output of auditory exercise coaching content (810). The voice coaching function can be implemented through voice-based human-robot interaction (HRI), and through the voice coaching function, guidance voices related to real-time exercise guidance for improving the user's exercise effect, provision of exercise program information, change of exercise type / intensity, encouragement, and praise can be provided.

[0136] During the user's exercise, auditory exercise coaching content (810) may be output through the speakers of the wearable device (100), the electronic device (210), the wireless earphones (222), and / or the smartwatch (224). In one embodiment, when the wireless earphones (222) and / or the smartwatch (224) are worn on the user's body and connected to the electronic device (210) and / or the wearable device (100), voice coaching content for a voice coaching function may be output through the wireless earphones (222) and / or the smartwatch (224). When the wireless earphones (222) and the smartwatch (224) are not connected, voice coaching content may be output through the electronic device (210) and / or the wearable device (100). Output control of the voice coaching content may be performed by the electronic device (210).

[0137] FIG. 8b is a drawing showing an example of outputting visual exercise coaching content (820, 830). The visual exercise coaching content (820) may be output through the display of an electronic device (210) or the visual exercise coaching content (830) may be output through the display of a smartwatch (224).

[0138] The auditory exercise coaching content (810) and the visual exercise coaching content (820, 830) may include the periodic coaching content, the immediate coaching content, the tendency coaching content, the progress coaching content, and the motivational coaching content described above, and may be output when each output condition defined in the exercise program is satisfied.

[0139] In one embodiment, the wearable device (100) and / or the electronic device (210) may provide a personalized exercise coaching function based on the user's exercise performance status by providing auditory exercise coaching content (810) and / or visual exercise coaching content (820, 830) while the user is performing an exercise program. The personalized exercise coaching function may improve the user's exercise effect, provide the user with an advanced exercise experience using the wearable device (100), and induce the user's active participation in exercise.

[0140] FIG. 9 is a diagram for explaining exercise goal indicators for each exercise program according to various embodiments and types of exercise coaching content provided according to the exercise program.

[0141] Referring to FIG. 9, a user can wear a wearable device (100) and perform various exercise programs (e.g., interval walking, power walking, target exercise volume walking). The wearable device (100) and / or the electronic device (210) can provide an exercise coaching function, and can provide an experience that allows the user to continue exercising by providing instantaneous coaching content, periodic coaching content, tendency coaching content, and progress coaching content according to the exercise program for exercise performance indicators (e.g., walking speed, stride length, walking symmetry indicator, number of steps, progress rate) measured during the user's exercise according to the exercise program selected by the user. The wearable device (100) and / or the electronic device (210) can determine the user's real-time exercise performance status and performance level to provide a personalized exercise coaching function for each user. The wearable device (100) and / or the electronic device (210) can provide exercise coaching and motivational coaching according to the user's exercise performance status.

[0142] For each exercise program, multiple exercise goal indicators and exercise coaching content to be provided may be defined in the exercise program information. In the illustrated table, the first exercise goal indicator may correspond to the most important main exercise goal indicator, and the second, third, and fourth exercise goal indicators may correspond to sub-exercise goal indicators. For example, according to the table, in the case of interval walking, walking speed may correspond to the main exercise goal indicator, and stride length, gait symmetry indicator, and heart rate may correspond to sub-exercise goal indicators. There may be priorities among the exercise goal indicators. For example, the priorities may decrease in the order of the first exercise goal indicator, the second exercise goal indicator, the third exercise goal indicator, and the fourth exercise goal indicator. Here, the priorities may indicate the order in which the multiple exercise goal indicators will be selected as the target of exercise coaching.

[0143] In one embodiment, exercise coaching content to be provided for each exercise program may be specified. For example, according to the table, when interval walking is performed, immediate coaching content, periodic coaching content, and tendency coaching content may be provided, but progress coaching content may not be provided. Motivational coaching content may be provided when a specified output condition is met, regardless of the type of exercise program.

[0144] FIG. 10 is a flowchart illustrating operations of a method of operating an electronic device that provides exercise coaching functions according to various embodiments.

[0145] Referring to FIG. 10, in operation (1010), an electronic device (210) may be connected to a wearable device (100). A user may wear the wearable device (100) to perform exercise using the wearable device (100). When the wearable device (100) is powered on and activated, the electronic device (210) may be connected to the wearable device (100) via wireless communication (e.g., Bluetooth communication). If this is the first time a connection is made between the wearable device (100) and the electronic device (210), a pairing process between the two devices may be performed first.

[0146] In operation (1020), the electronic device (210) may initiate an exercise program selected through the user input in response to receiving a user input. In one embodiment, information on recommended exercise programs may be provided to the user through the display of the electronic device (210), and the user may select an exercise program to perform among the recommended exercise programs while wearing the wearable device (100) through user input.

[0147] In operation (1030), the electronic device (210) may receive sensor data measured by one or more sensors of the wearable device (100) (e.g., the inertial sensor (522), the first angle sensor (524), and the second angle sensor (524-1) of FIG. 5) from the wearable device (100) worn on the user's body.

[0148] In operation (1040), the electronic device (210) may determine exercise coaching content based on exercise program information and sensor data of the exercise program while performing an exercise program using the wearable device (100). The exercise program information may include, for example, setting information about the exercise program (e.g., purpose and properties of the exercise program, progress time of the exercise program, exercise amount), information about exercise goal indicators set in the exercise program, and information about the type of exercise coaching content provided. The number of times and timing of provision of exercise coaching content may vary depending on the exercise amount set in the exercise program. The exercise program information may be stored in a separate database. The sensor data may include, for example, movement information of the wearable device (100) and sensing information about the terrain (e.g., uphill, downhill, flat ground) on which the user is exercising. In addition to the exercise program information and sensor data, the electronic device (210) may determine exercise coaching content based on setting information of the wearable device (100) (e.g., exercise mode, exercise intensity) and user information. User information may include, for example, age, gender, exercise ability measurements, BMI, medical conditions, medications taken, exercise goals, and exercise history (e.g., number of exercise sessions). User information may be stored in a separate database. Users can set their desired exercise goals (e.g., improving physical fitness, muscle strength, dieting, and maintaining good posture) and enter other user information through an application running on the electronic device (210). User information may be stored in a separate database.

[0149] Exercise coaching content may include periodic coaching content, instantaneous coaching content, tendency coaching content, progress coaching content, and motivational coaching content, as described above. The electronic device (210) may select exercise coaching content to be provided to the user based on the user's exercise performance status and the output conditions of each set exercise coaching content among periodic coaching content, instantaneous coaching content, tendency coaching content, progress coaching content, and motivational coaching content.

[0150] In operation (1050), the electronic device (210) can control the determined exercise coaching content to be output. If the exercise coaching content is auditory exercise coaching content, the electronic device (210) can control the exercise coaching content to be output through at least one of an audio output circuit (e.g., an audio output circuit (750) of FIG. 7), a wearable device (100), and wireless earphones (e.g., wireless earphones (222) of FIG. 2) connected to the electronic device (210). If the exercise coaching content is visual exercise coaching content, the electronic device (210) can control the exercise coaching content to be output through at least one of a display of a display circuit (e.g., a display circuit (740) of FIG. 7), a smartwatch (e.g., a smartwatch (224) of FIG. 2), and smartglasses (e.g., a smartglass (226) of FIG. 2).

[0151] In one embodiment, the electronic device (210) may utilize exercise program information, sensor data, and / or user information to provide real-time exercise coaching tailored to the user's exercise performance status. The electronic device (210) may provide personalized exercise coaching for each user that takes into account the user's characteristics based on the user information. The electronic device (210) may determine the user's real-time exercise performance status and performance information based on the sensor data, determine whether the user's performance falls short of, is appropriate for, or exceeds a target exercise goal indicator, and provide exercise coaching corresponding to the determination result. The electronic device (210) may select exercise coaching content based on exercise coaching items defined in the exercise program information.

[0152] In one embodiment, the electronic device (210) may determine whether to change the exercise goal indicator that is the target of exercise coaching and / or whether to change the provision conditions of exercise coaching content based on the user's performance level indicating the extent to which the user has performed the exercise for the exercise goal indicator. For example, the electronic device (210) may provide exercise coaching for a first exercise goal indicator, and if the user's performance level for the first exercise goal indicator satisfies the target condition, the electronic device (210) may provide exercise coaching for a second exercise goal indicator with the next highest priority. The electronic device (210) may provide exercise coaching information tailored to the user's exercise performance ability based on the user's real-time performance level, or may provide a personalized exercise coaching experience by changing the provision time of the exercise goal indicator and / or exercise coaching content. For example, if a situation arises where exercise coaching content must be output simultaneously, the electronic device (210) may omit the output of one exercise coaching content or change the output time (or output cycle). If the user's performance in an exercise session of a previously performed exercise program does not satisfy the target condition, the electronic device (210) may change the provision conditions of exercise coaching content to be provided in the next exercise session (e.g., shorten the output cycle). If exercise coaching content with the same comment is accumulated and output N (a natural number) or more times, the electronic device (210) may change the target condition for the exercise goal indicator or change the provision conditions of exercise coaching content (e.g., shorten the output cycle).

[0153] Hereinafter, embodiments of determining and providing exercise coaching content during an exercise coaching process will be described in more detail. While the descriptions below describe an embodiment in which exercise coaching content is provided under the control of an electronic device (210), the operations performed by the electronic device (210) to provide exercise coaching content may also be performed by a wearable device (100). Furthermore, the operations of providing exercise coaching content in the descriptions below may include directly outputting exercise coaching content or indirectly outputting it via another wearable device (e.g., wireless earphones, a smartwatch).

[0154] FIG. 11 is a flowchart illustrating operations for providing periodic coaching content according to various embodiments.

[0155] Referring to FIG. 11, exercise coaching may be performed according to the priority of exercise target indicators set in an exercise program while a user wearing a wearable device (100) is exercising. In operation (1110), the electronic device (210) may determine the user's performance level for a first exercise target indicator. For example, if the first exercise target indicator is walking speed, the electronic device (210) may measure the user's walking speed based on sensor data received from the wearable device (100). The measured walking speed may correspond to the performance level.

[0156] In operation (1120), the electronic device (210) may provide periodic coaching content for a first exercise target indicator according to a set time cycle. For example, the periodic coaching content may include an average value of measurement values ​​for the first exercise target indicator (e.g., walking speed) for the previous n seconds in a cycle of n (a natural number) (e.g., 30) seconds, and guidance comments regarding a target range set for the first exercise target indicator.

[0157] In operation (1130), the electronic device (210) can determine whether the performance for the first exercise target indicator satisfies the target range set for the first exercise target indicator.

[0158] In one embodiment, if the user's performance for the first exercise target metric does not satisfy the target range set for the first exercise target metric (e.g., if it is determined to be below or above the target range) (if operation (130) is determined as 'No'), the electronic device (210) may perform operation (1110) again. At this time, the electronic device (210) may provide periodic coaching content to guide that the user's performance is below or above the target for the first exercise target metric. For example, periodic coaching content such as "Your walking speed is slow. Maintain 6 km / h" may be provided. Thereafter, if the walking speed is determined to be still slow, periodic coaching content such as "Your walking speed is still slow. Maintain 6 km / h" may be provided.

[0159] In one embodiment, if the performance for the first exercise target indicator is determined to satisfy the target range (if 'yes' in operation (1130), the electronic device (210) may provide periodic coaching content to guide the user that the performance is appropriate for the target for the first exercise target indicator, and may perform exercise coaching for the second exercise target indicator. For example, periodic coaching content such as "Your walking speed is appropriate" may be provided.

[0160] In operation (1140), the electronic device (210) may determine the user's performance for a second exercise target metric. For example, if the second exercise target metric is stride length, the electronic device (210) may measure the user's stride length based on sensor data received from the wearable device (100). The measured stride length may correspond to the performance. The performance for the second exercise target metric may be determined in operation (1140) or may have been determined prior to operation (1140).

[0161] The second exercise goal indicator may be the highest priority exercise goal indicator among the multiple exercise goal indicators set in the exercise program, following the first exercise goal indicator. If the performance of the first exercise goal indicator is determined to meet the target range, exercise coaching for the second exercise goal indicator may be provided. In this way, exercise coaching for the second exercise goal indicator may be provided if the first exercise goal indicator is well maintained, and the exercise coaching content may be changed in real time during the user's exercise performance.

[0162] In operation (1150), the electronic device (210) may provide periodic coaching content for a second exercise target indicator at a predetermined time interval. For example, the periodic coaching content may include a measurement value for the current second exercise target indicator (e.g., stride length) at an interval of n (a natural number) seconds and guidance comments regarding a set goal for the second exercise target indicator.

[0163] In operation (1160), the electronic device (210) can determine whether the performance for the second exercise target indicator satisfies the target range set for the second exercise target indicator.

[0164] In one embodiment, if the user's performance for the second exercise target metric does not meet the target range set for the second exercise target metric (e.g., if it is determined to be below or above the target range) (if operation (160) is determined as 'No'), the electronic device (210) may perform operation (1140) again. At this time, the electronic device (210) may provide periodic coaching content to guide the user that the user's performance is below or above the target for the second exercise target metric. For example, periodic coaching content such as "Your stride is narrow. Maintain 50 cm" may be provided.

[0165] In one embodiment, if the performance for the second exercise target indicator is determined to meet the target range (if "yes" in operation (1160)), the electronic device (210) may provide periodic coaching content to guide the user's performance to be appropriate for the target for the second exercise target indicator, and may provide exercise coaching for the third exercise target indicator. For example, periodic coaching content such as "Your stride is appropriate" may be provided.

[0166] In operation (1170), the electronic device (210) may determine the user's performance for a third exercise goal indicator. For example, if the third exercise goal indicator is the number of steps, the electronic device (210) may measure the user's number of steps based on sensor data received from the wearable device (100). The measured number of steps may correspond to the performance indicator. The performance indicator for the third exercise goal indicator may be determined in operation (1170) or may have been determined prior to operation (1170).

[0167] The third exercise goal indicator may be the highest priority exercise goal indicator among the multiple exercise goal indicators set in the exercise program, following the second exercise goal indicator. If performance for the second exercise goal indicator is determined to meet the target range, exercise coaching for the third exercise goal indicator may be provided. Thus, exercise coaching for the third exercise goal indicator may be provided if the first and second exercise goal indicators are well-maintained.

[0168] In operation (1180), the electronic device (210) may provide periodic coaching content for a third exercise goal indicator at a predetermined time interval. For example, the periodic coaching content may include a measurement value for the current third exercise goal indicator (e.g., number of steps) at a period of n (a natural number) seconds and guidance comments regarding a goal set for the third exercise goal indicator.

[0169] Afterwards, for the third exercise goal indicator, the performance and target range can be compared in the same way as for the first and second exercise goal indicators, and it can be decided whether to provide exercise coaching for the fourth exercise goal indicator with the next priority.

[0170] Figure 12 is a flowchart illustrating operations for providing instant coaching content according to various embodiments.

[0171] Referring to FIG. 12, in operation (1210), the electronic device (210) may determine the user's performance with respect to a first exercise target indicator. For example, if the first exercise target indicator is walking speed, the electronic device (210) may measure the user's walking speed based on sensor data received from the wearable device (100).

[0172] In operation (1220), the electronic device (210) may determine whether the change in performance for the first exercise target metric is greater than a threshold value. For example, it may be determined whether the change in the average value of the performance for the first exercise target metric is greater than 20%. The electronic device (210) may determine whether the average value of the performance for the first exercise target metric has changed drastically during the time interval of the previous n (natural number) seconds. The drastic change in the average value may include the average value rapidly increasing or decreasing.

[0173] If the change in performance for the first exercise target indicator is determined to be greater than the threshold value (yes in operation (1220)), the electronic device (210) may provide immediate coaching content for the first exercise target indicator in operation (1230). For example, if the walking speed suddenly slows down, the immediate coaching content of “You suddenly became too slow! Focus!” may be provided. If the walking speed suddenly increases, the immediate coaching content of “You suddenly became too fast at 7.1 km / h! Be careful!” may be provided. After providing such attention immediate coaching content, a goal guidance comment for the first exercise target indicator (e.g., “Our target walking speed is 6.2 km / h”) may be provided.

[0174] In operation (1240), the electronic device (210) may provide motivational coaching content when a specific condition is met. The electronic device (210) may provide motivational coaching content based on user information. If the purpose of the exercise program and the exercise purpose set by the user are the same, the specific condition may be determined to be met. In this case, motivational coaching content may be provided to remind the user of the exercise purpose and encourage exercise motivation. For example, motivational coaching content such as "You said the exercise purpose is to improve muscle strength! You should work harder to stimulate your muscles!" or "You said the exercise purpose is to manage weight! So you should work harder to lose weight!" may be provided. If the purpose of the exercise program and the exercise purpose set by the user are not the same, motivational coaching content may not be provided.

[0175] Figure 13 is a flowchart illustrating operations for providing tendency coaching content according to various embodiments.

[0176] Referring to FIG. 13, in operation (1310), the electronic device (210) may determine the user's performance for a first exercise target indicator during a predetermined time period. For example, if the first exercise target indicator is walking speed, the electronic device (210) may measure the average value of the user's walking speed for the preceding n (natural number) minutes based on sensor data received from the wearable device (100).

[0177] In operation (1320), the electronic device (210) can determine whether the performance determined in operation (1310) is within a set target range when the transmitted time period is reached.

[0178] If the performance is determined to be within a set target range (yes in operation (1320)), the electronic device (210) may provide first tendency coaching content including comments to motivate the user's exercise performance in operation (1330). The first tendency coaching content may include comments indicating a tendency of the user's exercise performance, comments regarding a goal for the first exercise goal indicator, and comments regarding attribute information of the current exercise section. For example, the first tendency coaching content may include comments such as "The speed is appropriate for 3 minutes," "You have an excellent sense of speed!", and "It must have been difficult because it was a fast walking section, but you did a great job."

[0179] If the performance is determined to be not within a set target range (e.g., exceeding or falling short of the target range) (e.g., 'No' in operation (1320)), in operation (1340), the electronic device (210) may provide second tendency coaching content including a first exercise target index and a guidance comment for informing the user of the result of the trend analysis for the user's exercise. The second tendency coaching content may include comments indicating a tendency for the user's exercise performance, comments regarding a target for the first exercise target index, and comments regarding attribute information of the exercise section being currently exercised. If the performance falls below the set target range, the second tendency coaching content may include comments such as, "Your speed is slow for 3 minutes," "Maintain 6 km / h," and "Of course, it may be difficult because it is a fast walking section." If performance exceeds the established target range, second-tendency coaching content might include comments such as, "You're fast for 3 minutes," "Maintain 6 km / h," or "Of course, you might find yourself walking fast due to inertia. I understand."

[0180] In operation (1350), the electronic device (210) may provide motivational coaching content when a specific condition is met. Operations for providing motivational coaching content after providing tendency coaching content are described in detail below with reference to FIG. 14.

[0181] FIG. 14 is a flowchart illustrating operations for providing motivational coaching content after providing tendency coaching content according to various embodiments.

[0182] Referring to Figure 14, a flowchart depicts the actions of providing motivational coaching content after the user receives trend-based coaching content that points out the user's performance level on the first exercise goal indicator. The electronic device (210) may provide motivational coaching content based on user information to sympathize with and comfort the user's poor performance.

[0183] In operation (1410), the electronic device (210) may provide tendency coaching content. The electronic device (210) may provide tendency coaching content according to the process of operation (1310) to operation (1340) of FIG. 13.

[0184] After providing the tendency coaching content, the electronic device (210) may measure changes in the user's performance with respect to the first exercise target indicator in operation (1420). The electronic device (210) may determine changes in performance by comparing the user's existing performance measurement results with the content of the tendency coaching content.

[0185] In operation (1430), the electronic device (210) may provide motivational coaching content based on changes in performance. If the measured performance falls below the target range for the first exercise goal indicator after providing the tendency coaching content, the electronic device (210) may provide motivational coaching content for empathy. For example, motivational coaching content such as "Your measurement records show that your speed is slow, so it may be more difficult." may be provided. Additionally, if the user's age is identified as being above a certain age range (e.g., 70s) based on user information, the electronic device (210) may provide motivational coaching content that takes into account an older age range, such as "If you are of your age, it is natural that you would have difficulty maintaining this walking speed."

[0186] If the measured performance exceeds the target range for the first exercise goal indicator after providing the trend coaching content, the electronic device (210) may provide motivational coaching content for empathy. Additionally, the electronic device (210) may provide comments indicating information about the measured performance and the target range.

[0187] In one embodiment, the electronic device (210) may provide motivational coaching content with encouraging comments such as, "Stay strong! If you work hard every day, you'll see progress before you know it!" when performance exceeds or falls short of the target range for the first exercise goal indicator.

[0188] In operation (1440), the electronic device (210) may determine whether the amount of exercise performed by the user satisfies a set condition. For example, if the amount of exercise performed by the user is 70% or more of the scheduled amount of exercise or the exercise time is more than 30 minutes, the amount of exercise performed by the user may be determined to satisfy the set condition.

[0189] If the amount of exercise performed is determined to satisfy the set condition (i.e., "yes" in operation (1440)), the electronic device (210) may provide motivational coaching content in operation (1450). The electronic device (210) may provide motivational coaching content that may include empathetic comments regarding the user's high amount of exercise. For example, motivational coaching content such as "It's great that you're doing a lot of exercise!" may be provided.

[0190] FIG. 15 is a flowchart illustrating operations for providing progress coaching content according to various embodiments.

[0191] Each exercise program may have defined progress coaching points based on the amount of exercise time. For example, progress coaching content may be provided at 10%, 20%, 50%, 70%, and 100% of the total exercise time set for the program.

[0192] In operation (1510), the electronic device (210) may determine the user's performance with respect to a first exercise target indicator. For example, if the first exercise target indicator is walking speed, the electronic device (210) may measure the user's walking speed based on sensor data received from the wearable device (100).

[0193] In operation (1520), the electronic device (210) may determine whether the progress (or progress rate) of the exercise program satisfies a set condition. For example, the electronic device (210) may determine whether the progress (e.g., exercise time performed so far) of the exercise program corresponds to 10%, 20%, 50%, 70%, or 100% of the total exercise time set in the exercise program.

[0194] If the progress of the exercise program is determined to satisfy the set condition (if 'yes' in operation (1520)), in operation (1530) the electronic device (210) may provide progress coaching content including guidance comments to inform progress information on the performance of the exercise program.

[0195] In one embodiment, the electronic device (210) may compare and determine the amount of exercise completed and the amount of exercise remaining. If the amount of exercise remaining is greater than the amount of exercise completed, the electronic device (210) may provide progress coaching content including comments to guide the amount of exercise completed and the amount of exercise remaining. For example, progress coaching content including comments such as "You've already completed 40% of the exercise" and "There are 6,200 steps left. Let's try a little harder!" may be provided. If the amount of exercise remaining is less than the amount of exercise completed, the electronic device (210) may provide progress coaching content including comments to guide the estimated amount of exercise remaining (or remaining time), such as "You have about 35 minutes left to achieve your goal," along with comments to guide the progress information so far.

[0196] In operation (1540), the electronic device (210) may determine whether the provided progress coaching session corresponds to the last session. The electronic device (210) may determine whether the progress coaching content provided in operation (1530) is intended to guide the completion or termination of the exercise. If the provided progress coaching session does not correspond to the last session (i.e., "No" in operation (1540), the electronic device (210) may return to operation (1510) to continue performing the progress coaching. In one embodiment, if the provided progress coaching content in operation (1530) is the first session, the electronic device (210) may provide a comment guiding tip information related to the exercise performance. For example, a comment such as "If you want to walk for a long time without getting bored, try using an exercise mode with varying exercise intensity" may be provided.

[0197]

[0198] Figure 16 is a flowchart illustrating operations in which exercise coaching is performed by changing exercise target indicators according to various embodiments.

[0199] Referring to FIG. 16, a flowchart of operations for performing exercise coaching by changing an exercise target index when a specific condition is satisfied in relation to an operation for controlling the output of exercise coaching content is illustrated. During the exercise coaching process, whether to change the priority of exercise coaching between the main exercise target index and one or more sub-exercise target indexes is determined based on the user's real-time exercise performance, and exercise coaching for the exercise target index with the highest priority can be provided according to the user's exercise performance status.

[0200] In operation (1610), the electronic device (210) may determine the user's performance for a first exercise target indicator (e.g., walking speed) specified in exercise program information based on sensor data received from the wearable device (100). For example, the electronic device (210) may extract signal feature points from the sensor data and determine walking speed, stride length, hip joint angle, calorie consumption, heart rate, and walking symmetry indicators based on the time interval between the extracted feature points and / or the size of the feature points. As another example, the electronic device (210) may obtain performance for each of the exercise target indicators (e.g., walking speed, stride length, hip joint angle, calorie consumption, heart rate, and walking symmetry indicator) from the performance determination model by inputting sensor data of an inertial sensor (e.g., an inertial sensor (522) of FIG. 5) and sensor data of an angular sensor (e.g., a first angular sensor (524), a second angular sensor (524-1) of FIG. 5) obtained from the wearable device (100) into a learned neural network-based performance determination model.

[0201] In operation (1620), the electronic device (210) may control to output first exercise coaching content for the first exercise goal index based on the performance level for the determined first exercise goal index. The first exercise goal index may correspond to a main exercise goal index set in the exercise program being performed. The electronic device (210) may provide first exercise coaching content of periodic coaching content, instantaneous coaching content, tendency coaching content, progress coaching content, and / or motivational coaching content for the first exercise goal index. When an output condition set for each of the first exercise coaching contents of periodic coaching content, instantaneous coaching content, tendency coaching content, progress coaching content, and / or motivational coaching content is satisfied, the electronic device (210) may control to output the first exercise coaching content that satisfies the output condition.

[0202] The electronic device (210) may determine whether to change the priority of exercise coaching between the main exercise goal index and one or more sub exercise goal indexes based on the performance for the first exercise goal index determined in real time during the user's exercise performance. In operation (1630), the electronic device (210) may determine whether the determined performance satisfies the target condition set for the first exercise goal index. For example, if the performance for the first exercise goal index satisfies the defined target range N (a natural number) times in a row, the performance may be determined to satisfy the target condition set for the first exercise goal index. If the performance for the first exercise goal index falls below or exceeds the defined target range, the performance may be determined to not satisfy the target condition. If the performance is determined to not satisfy the target condition ('No' in operation (1630)), the electronic device (210) may continue to perform the exercise coaching process for the first exercise goal index of operations (1610) and (1620).

[0203] If the performance is determined to satisfy the target condition set for the first exercise target indicator (if 'Yes' in operation (1630)), exercise coaching may be performed for a second exercise target indicator (e.g., stride length) having a lower priority than the first exercise target indicator. The electronic device (210) may set the second exercise target indicator as the main exercise target indicator and perform exercise coaching. At this time, exercise coaching for the first exercise target indicator may be omitted. The priority between exercise target indicators including the first exercise target indicator and the second exercise target indicator may be specified in exercise program information. The purpose of exercise coaching performed by the electronic device (210) is to help the user exercise while keeping the exercise goal well. If the electronic device (210) determines that the user is performing the main exercise target indicator well, exercise coaching may be performed focusing on other exercise target indicators so that the user can also perform other exercise target indicators well.

[0204] In one embodiment, when selecting a second exercise target indicator for which exercise coaching will be performed following the first exercise target indicator, the electronic device (210) may select the second candidate exercise target indicator with the highest priority among a plurality of second candidate exercise target indicators specified in the exercise program information as the second exercise target indicator for which exercise coaching will be performed. The priorities among the second candidate exercise target indicators may be preset in the exercise program information or adjusted based on the user's exercise purpose and / or the user's existing disease.

[0205] In one embodiment, the electronic device (210) may select a second candidate exercise goal index that is determined to require relatively more exercise coaching among second candidate exercise goal indexes corresponding to sub exercise goal indexes, and may determine to perform exercise coaching on the selected second candidate exercise goal index. For example, the electronic device (210) may select a second candidate exercise goal index with the lowest performance among a plurality of second candidate exercise goal indexes specified in exercise program information as the second exercise goal index for which exercise coaching will be performed. The electronic device (210) may select a second candidate exercise goal index with the greatest difference in performance from a goal defined in an exercise program among the second candidate exercise goal indexes as the second exercise goal index for which exercise coaching will be performed.

[0206] If the performance for the first exercise target metric is determined to satisfy the target condition set for the first exercise target metric (if 'yes' in operation (1630)), the electronic device (210) may determine the user's performance for the second exercise target metric in operation (1640). For example, if the second exercise target metric is stride length, the electronic device (210) may measure changes in the user's stride length over time based on sensor data received from the wearable device (100).

[0207] In operation (1650), the electronic device (210) may control the output of second exercise coaching content for the second exercise goal indicator based on the performance level for the determined second exercise goal indicator. The electronic device (210) may provide second exercise coaching content of periodic coaching content, instantaneous coaching content, tendency coaching content, progress coaching content, and / or motivational coaching content for the second exercise goal indicator.

[0208] In operation (1660), the electronic device (210) may determine whether the exercise program has ended. If the exercise program has not ended (if operation (1660) is 'No'), the electronic device (210) may return to operation (1630) to determine whether the performance determined for the first exercise target metric satisfies the target condition set for the first exercise target metric. If the electronic device (210) determines that the performance for the first exercise target metric does not satisfy the target condition set for the first exercise target metric while performing exercise coaching for the second exercise target metric (if operation (1630) is 'No'), the electronic device (210) may stop exercise coaching for the second exercise target metric and start exercise coaching for the first exercise target metric again. If the electronic device (210) determines that the original main exercise target metric does not satisfy the target condition, the electronic device (210) may stop exercise coaching for the candidate exercise target metric and perform exercise coaching for the main exercise target metric again. If the electronic device (210) determines that the user is not performing well on a higher priority exercise goal indicator, it can give priority to exercise coaching on the higher priority exercise goal indicator.

[0209] Although the present embodiment has described an embodiment that changes between exercise coaching for a first exercise target indicator and exercise coaching for a second exercise target indicator, the scope of the embodiment is not limited thereto. In addition to the first exercise target indicator and the second exercise target indicator, exercise coaching for a third exercise target indicator and / or a fourth exercise target indicator may also be performed. For example, if a specific condition is satisfied during exercise coaching for the second exercise target indicator (e.g., if the performance for the second exercise target indicator satisfies the target condition set for the second exercise target indicator), exercise coaching for the third exercise target indicator may be performed, and if a specific condition is satisfied during exercise coaching for the third exercise target indicator (e.g., if the performance for the third exercise target indicator satisfies the target condition set for the third exercise target indicator), exercise coaching for the fourth exercise target indicator may be performed.

[0210] FIG. 17 is a flowchart illustrating processing when duplication occurs between outputs of exercise coaching contents according to various embodiments.

[0211] Referring to FIG. 17, in operation (1710), the electronic device (210) can detect that the output condition of the exercise coaching content is satisfied.

[0212] In operation (1720), the electronic device (210) may determine whether a situation of duplicate output of at least two types of exercise coaching content (e.g., periodic coaching content, instantaneous coaching content, tendency coaching content, and progress coaching content) is expected. For example, a situation of duplicate output of exercise coaching content may be expected to occur when an output condition of at least two types of exercise coaching content is simultaneously satisfied.

[0213] If a situation of duplicate output of exercise coaching contents is not expected (if 'No' in operation (1720)), in operation (1730), the electronic device (210) can control the output of exercise coaching contents that satisfy the output condition in operation (1710).

[0214] If a situation of overlapping output of exercise coaching contents is expected (if 'yes' in operation (1720)), in operation (1740), the electronic device (210) can control to output exercise coaching contents having a higher (or highest) priority in relation to output among exercise coaching contents that satisfy output conditions. Priorities in relation to output may be predefined among periodic coaching contents, immediacy coaching contents, tendency coaching contents, progress coaching contents, and motivational coaching contents. For example, immediacy coaching contents may have the highest priority, followed by tendency coaching contents, periodic coaching contents, and progress coaching contents. The electronic device (210) can compare the priorities among exercise coaching contents that satisfy output conditions and output only the exercise coaching contents having the highest priority.

[0215] In operation (1750), the electronic device (210) may determine whether the lower priority exercise coaching content is periodic coaching content. If the lower priority exercise coaching content is not periodic coaching content ('No' in operation (1750), then in operation (1760), the electronic device (210) may control the lower priority exercise coaching content not to be output. For example, if the output conditions for both the immediate coaching content and the tendency coaching content are satisfied, the immediate coaching content may be output and the tendency coaching content may not be output. In this way, if an overlapping output situation of exercise coaching content is expected, the exercise coaching content with the highest priority may be determined to be output, and the output of other exercise coaching content may be omitted.

[0216] If the lower priority exercise coaching content is periodic coaching content (if 'yes' in operation (1750)), the electronic device (210) may adjust the output cycle of the periodic coaching content in operation (1770). In one embodiment, if the periodic coaching content is not output due to an expected overlapping output situation with the immediate coaching content or the tendency coaching content, the output cycle of the periodic coaching content may be reset based on the time at which the immediate coaching content or the tendency coaching content is output, thereby adjusting the output cycle.

[0217]

[0218] FIG. 18 is a flowchart illustrating a process for changing the output conditions of exercise coaching content according to a user's performance according to various embodiments.

[0219] The operations (1610), (1620), and (1630) illustrated in FIG. 18 are identical to the operations (1610), (1620), and (1630) of FIG. 16 described above, and any duplicate descriptions are omitted.

[0220] If it is determined that the performance for the first exercise target indicator does not satisfy the target condition set for the first exercise target indicator (if 'No' in operation (1630)), in operation (1810) the electronic device (210) can determine whether the number of times the first exercise coaching content of the same comment has been output has reached a threshold number of times (e.g., N (a natural number) times).

[0221] If it is determined that the number of times the first exercise coaching content of the same comment is output has reached a threshold number (if 'Yes' in operation (1810)), in operation (1820), the electronic device (210) may change the output cycle of the first exercise coaching content and / or change the target condition for the first exercise goal indicator. If the output cycle of the first exercise coaching content is changed, the electronic device (210) may provide a comment to the user to guide the change in the output cycle. For example, a comment may be provided to the user to guide the change in the output cycle of the exercise coaching content, such as "I will coach your walking speed more frequently in the future."

[0222] In one embodiment, the electronic device (210) may change the output timing of the first exercise coaching content depending on the correlation between periodic coaching content, instantaneous coaching content, tendency coaching content, and progress coaching content that may be provided as the first exercise coaching content. For example, when the instantaneous coaching content or tendency coaching content is repeatedly output with the same comment (or the same content), the electronic device (210) may adjust the output conditions of the tendency coaching content. If the user's exercise performance is determined to be insufficient, the exercise coaching may be performed more tightly (e.g., the time condition among the output conditions of the tendency coaching content may be shortened), and if the user is determined to be performing the exercise well, the output conditions of the tendency coaching content may be adjusted so that the exercise coaching may be performed more leisurely (e.g., the time condition among the output conditions of the tendency coaching content may be lengthened). Assume that the time set for tendency judgment for the tendency coaching content is 2 minutes. If the time limit for trend coaching content is shortened, for example, the time set for trend assessment is shortened to 1 minute, and trend coaching content such as "Your walking speed was slow for 1 minute" may be output. If the time limit for trend coaching content is lengthened, for example, the time limit for trend assessment is lengthened to 3 minutes, and trend coaching content such as "Your walking speed was appropriate for 3 minutes" may be output.

[0223] In one embodiment, if the progress coaching content is analyzed and it is determined that the user's exercise performance pace is gradually declining, the electronic device (210) may reduce the output frequency of the periodic coaching content and / or trend coaching content output for the exercise coaching for the sub-exercise goal indicator. In this case, the electronic device (210) may provide exercise coaching more frequently to prevent the user's pace from declining.

[0224] In one embodiment, when it is determined that the number of times the first exercise coaching content of the same comment has been outputted has reached a threshold number of times and the target condition for the first exercise goal indicator is changed, the target condition for the first exercise goal indicator may be adjusted depending on whether the user's performance for the first exercise goal indicator is appropriate, under, or over. At this time, the performance for the first exercise goal indicator that the user is expected to have achieved so far may also be adjusted. When the first exercise coaching content indicating that the performance for the first exercise goal indicator is under a target range set for the first exercise goal indicator is being repeatedly output, the electronic device (210) may maintain or lower the target condition for the first exercise goal indicator. When the first exercise coaching content indicating that the performance for the first exercise goal indicator is over or within a target range set for the first exercise goal indicator is being repeatedly output, the electronic device (210) may raise the target condition for the first exercise goal indicator. For example, if the user's walking speed continues to fall within a range greater than 4 km / h and less than 6 km / h of the target range set for walking speed, the target range for walking speed can be changed to a range greater than 4.5 km / h and less than 5.5 km / h.

[0225] FIGS. 19A and 19B are drawings illustrating an example in which an exercise target index that is the target of exercise coaching is changed during exercise performance according to various embodiments.

[0226] Referring to FIGS. 19A and 19B , in operation (1910), a user may select an exercise program (e.g., an interval walking program) to be performed through an application running on an electronic device (210) and command the start of the exercise program. The user may select an exercise program through user input and request the start of the exercise program.

[0227] In operation (1920), an exercise program is performed, and sensor data may be acquired by one or more sensors of the wearable device (100) (e.g., the inertial sensor (522), the first angle sensor (524), and the second angle sensor (524-1) of FIG. 5 ). The sensor data may be transmitted to the electronic device (210). The electronic device (210) may calculate a user's performance (or measurement value) corresponding to each of the exercise target indices (e.g., walking speed, stride length, heart rate, and number of steps) set in the exercise program based on the sensor data. According to an embodiment, the wearable device (100) may calculate a user's performance corresponding to each of the exercise target indices based on the sensor data, and the calculated performance may be transmitted to the electronic device (210).

[0228] In operation (1930), exercise coaching for a first exercise target index set in the exercise program information of the exercise program being performed can be performed in real time. The first exercise target index can correspond to the main exercise target index with the highest priority. The exercise program information can define the types of exercise coaching content provided for each exercise target index, and the electronic device (210) can provide the exercise coaching content set for the first exercise target index to the user. The exercise coaching content can be output from at least one of the wearable device (100), the electronic device (210), the wireless earphones (222), and the smartwatch (224). If the first exercise target index is walking speed, the electronic device (210) can provide exercise coaching content of immediate coaching content, periodic coaching content, and tendency coaching content centered on walking speed. For example, periodic coaching content such as "Walk a little slower than now" can be provided to the user in relation to the user's walking speed.

[0229] In operation (1940), if the user's performance for the first exercise target indicator (e.g., walking speed) is determined to be appropriate, the electronic device (210) may perform exercise coaching for a second exercise target indicator (e.g., stride length) that has a lower priority than the first exercise target indicator. For example, if the user's walking speed is continuously output with a complimentary periodic coaching content N (e.g., 3) times, the electronic device (210) may determine that the user's walking speed is appropriate. The second exercise target indicator may correspond to a sub-exercise target indicator defined in the exercise program settings. If there are multiple sub-exercise target indicators, it may be determined to perform exercise coaching for the sub-exercise target indicator with the lowest performance or the sub-exercise target indicator with the highest priority among the sub-exercise target indicators. If the target of exercise coaching has changed, the electronic device (210) may provide a comment to the user to inform him / her that the exercise target indicator for exercise coaching has changed. For example, a comment such as "From now on, I will coach you with a focus on stride length" may be provided to the user.

[0230] In operation (1950), the electronic device (210) determines the user's performance level for a second exercise target indicator and performs exercise coaching for the second exercise target indicator based on the determined performance level. If the second exercise target indicator is stride length, the electronic device (210) may change stride length to the main exercise target indicator and provide the user with immediate coaching content, periodic coaching content, and tendency coaching content for stride length. For example, in relation to the user's stride length, periodic coaching content such as "Your stride is narrow. Try walking with wider steps" may be provided to the user.

[0231] In operation (1960), if the user's performance for the second exercise target indicator (e.g., stride length) is determined to be appropriate, the electronic device (210) may perform exercise coaching for a third exercise target indicator (heart rate) that has a lower priority than the second exercise target indicator. For example, if the user's stride length is continuously output with a complimentary periodic coaching content N (e.g., 3) times, the electronic device (210) may determine that the user's stride length is appropriate. In the exercise program information, the third exercise target indicator may be designated as having a lower priority than the second exercise target indicator. The third exercise target indicator may be a sub-exercise target indicator with the second highest priority among the sub-exercise target indicators. If the target of the exercise coaching changes, the electronic device (210) may provide a comment to the user to inform him / her that the exercise target indicator that is the target of the exercise coaching has changed. For example, the comment "From now on, I will coach you focusing on heart rate" may be provided to the user.

[0232] In operation (1970), the electronic device (210) may determine the user's performance level for a third exercise target indicator and perform exercise coaching for the third exercise target indicator based on the determined performance level. If the third exercise target indicator is heart rate, the electronic device (210) may change heart rate to the main exercise target indicator and provide the user with instantaneous coaching content, periodic coaching content, and tendency coaching content for heart rate. For example, tendency coaching content such as "Your heart rate tends to be low at level 2" may be provided to the user in relation to the user's heart rate.

[0233] In operation (1980), if the electronic device (210) continuously measures the performance for a first exercise target indicator (e.g., walking speed) and detects that the performance does not meet the target condition, the electronic device (210) may change the target of exercise coaching to the first exercise target indicator. For example, if the electronic device (210) determines that the walking speed has fallen below the target range for N (e.g., 3) times while performing exercise coaching for heart rate, the electronic device (210) may stop the exercise coaching for heart rate and resume exercise coaching for walking speed. If the first exercise target indicator is walking speed, the electronic device (210) may again provide exercise coaching content of immediate coaching content, periodic coaching content, and tendency coaching content centered on walking speed. For example, exercise coaching for heart rate may be stopped, and periodic coaching content such as “Your walking speed is slow. Try walking faster than now” may be provided to the user in relation to the user’s walking speed.

[0234]

[0235] FIG. 20 is a diagram illustrating an example of exercise coaching in the case where there is overlap between the outputs of exercise coaching contents according to various embodiments.

[0236] Referring to FIG. 20, in operation (2010), a user may select an exercise program (e.g., an interval walking program) to be performed through an application running on an electronic device (210) and command the start of the exercise program.

[0237] In operation (2020), an exercise program is performed, and sensor data may be acquired by one or more sensors of the wearable device (100). The sensor data may be transmitted to an electronic device (210). The electronic device (210) may calculate the user's performance (or measurement value) corresponding to each of the exercise target indicators set in the exercise program based on the sensor data. Based on the user's performance, exercise coaching for the first exercise target indicator set in the exercise program information may be performed in real time.

[0238] During exercise coaching for the first exercise goal indicator, the electronic device (210) may determine whether a situation of overlapping output of at least two exercise coaching contents among multiple types of exercise coaching contents (e.g., periodic coaching contents, instantaneous coaching contents, tendency coaching contents, progress coaching contents) is expected. For example, a situation of overlapping output of exercise coaching contents may be expected to occur when an output condition of at least two exercise coaching contents is simultaneously satisfied. If a situation of overlapping output of exercise coaching contents is expected, the electronic device (210) may provide exercise coaching contents with the highest priority.

[0239] For example, assuming that the first exercise target indicator is walking speed and that the output of the tendency coaching content is higher priority than the periodic coaching content. In this case, if the output conditions of the periodic coaching content for walking speed and the tendency coaching content for walking speed are simultaneously satisfied, as in operation (2030), the electronic device (210) may provide only the tendency coaching content with a higher priority, “It suddenly became too fast! Be careful!” to the user, and may not provide the periodic coaching content. The electronic device (210) may change the output cycle of the periodic coaching content, and when the changed output cycle of the periodic coaching content is reached, as in operation (2040), provide the periodic coaching content “Your walking speed is appropriate” to the user.

[0240] FIG. 21 is a diagram illustrating examples of changing the output conditions of exercise coaching content according to the user's exercise performance status according to various embodiments.

[0241] The operations (2010) and (2020) illustrated in Fig. 21 are identical to the operations (2010) and (2020) illustrated in Fig. 20 described above, and any duplicate descriptions will be omitted. While exercise coaching is being performed for a first exercise target indicator (e.g., walking speed), the electronic device (210) can determine whether the performance for the first exercise target indicator satisfies the target condition set for the first exercise target indicator.

[0242] In operation (2130), the electronic device (210) may change the output timing of the first exercise coaching content depending on whether the user's performance for the first exercise target indicator satisfies the target condition set for the first exercise target indicator. If the user's performance continues to fall short of the target condition and thus the user's exercise performance is determined to be poor, the electronic device (210) may change the exercise coaching based on the first exercise coaching content to be tighter. For example, the electronic device (210) may reduce the output cycle of the periodic coaching content and the output cycle of the tendency coaching content, and decrease the threshold for determining whether to output the instantaneous coaching content. If the user's performance continues to meet the target condition and thus the user's exercise performance is determined to be good, the electronic device (210) may change the exercise coaching based on the first exercise coaching content to be looser. The electronic device (210) may, for example, increase the output cycle of the periodic coaching content and the output cycle of the tendency coaching content, and increase the threshold for determining whether to output the instantaneous coaching content.

[0243] If the output cycle of the first exercise coaching content changes, the electronic device (210) may provide a comment to the user to inform them of the change in the output cycle. For example, a comment such as "From now on, I will coach your walking speed more frequently" may be provided to the user to inform them of the change in the output cycle of the exercise coaching content.

[0244] In operation (2140), the electronic device (210) may change the target condition for the first exercise target indicator depending on whether the user's performance for the first exercise target indicator satisfies the target condition set for the first exercise target indicator. The target condition for the first exercise target indicator may be adjusted depending on whether the user's performance for the first exercise target indicator is appropriate, under- or over-achievable. For example, if the user continues to meet the target condition by increasing the walking speed, the target range set for the walking speed may be increased. For example, if the target range for the previously set walking speed was a section greater than 4 km / h and less than 6 km / h, the target range may be changed to a section greater than 4.5 km / h and less than 5.5 km / h.

[0245] If the target condition for the first exercise target indicator changes, the electronic device (210) may provide a comment to the user informing them that the target condition, which serves as the evaluation criteria for the user's exercise performance for the first exercise target indicator, has changed. For example, a comment such as "From now on, I will coach your walking speed in more detail." may be provided to the user.

[0247] The computer-executable instructions, when individually or collectively executed by the one or more processors (710), may cause the electronic device (210) to perform an operation of controlling the output of exercise coaching content based on exercise program information and sensor data of the exercise program during the execution of the exercise program using the wearable device (100). The sensor data may be measured by one or more sensors (522; 524; 524-1) of the wearable device (100) and received through the communication circuit (730). The operation of controlling the output of the exercise coaching content may include an operation of determining the user's performance for a first exercise target index specified in the exercise program information based on sensor data received from the wearable device (100), an operation of controlling the output of the first exercise coaching content for the first exercise target index based on the user's performance for the determined first exercise target index, an operation of determining the user's performance for a second exercise target index specified in the exercise program information and having a lower priority than the first exercise target index based on a determination that the determined user's performance satisfies a target condition set for the first exercise target index, and an operation of controlling the output of the second exercise coaching content for the second exercise target index based on the user's performance for the determined second exercise target index.

[0256] The above-mentioned tendency coaching content may include a comment to motivate the user to perform exercise when the performance for the first exercise goal indicator measured during the predetermined time period is within the target range, and may include a guidance comment to inform the user of the first exercise goal indicator and the result of a tendency analysis for the user's exercise when the performance for the first exercise goal indicator measured during the predetermined time period is not within the target range.

[0257] The operation of determining the user's performance for the second exercise goal indicator may include an operation of selecting a second candidate exercise goal indicator having the highest priority among a plurality of second candidate exercise goal indicators specified in the exercise program information as the second exercise goal indicator, and an operation of determining the user's performance for the selected second exercise goal indicator.
