[0027] Hereinafter, various embodiments of the present disclosure will be described with reference to the attached drawings. However, this is not intended to limit the present disclosure to specific embodiments, and it should be understood that the present disclosure encompasses various modifications, equivalents, and / or alternatives of the embodiments.

[0028]

[0029] FIG. 1 is a drawing for explaining an overview of a wearable device worn on a user's body according to one embodiment.

[0030] 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, exercise, and / or work. In one embodiment, 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 the embodiments, the term 'wearable device' may be replaced with 'wearable robot', 'walking assistance device', or 'exercise assistance device'. The user (110) may be a human or an animal, but is not limited thereto. A wearable device (100) may be worn on a user's (110) body (e.g., lower body (legs, ankles, knees, etc.), upper body (torso, arms, wrists, etc.), or waist) 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'.

[0031] 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 (120) 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 pedestrian with abnormal walking habits or walking posture.

[0032] In one embodiment, the wearable device (100) may operate in an exercise assistance mode to enhance the exercise effect of the user (110). In the exercise assistance mode, the wearable device (100) may impede the body movement of the user (110) or provide resistance to the body movement of the user (110) by applying a resistance force generated from the driving module (120) 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, thereby further enhancing the exercise effect on the legs of the user (110). In one embodiment, the wearable device (100) may also apply an assistive force to the body of the user (110) to assist the exercise of the user (110). For example, when a disabled person or an elderly person wears a wearable device (100) to exercise, the wearable device (100) may provide assistive force to assist body movements during the exercise. In one embodiment, the wearable device (100) may provide a combination of assistive force and resistance force by exercise section or time section, such as providing assistive force in some exercise sections and resistance force in other exercise sections.

[0033] 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 sensors (e.g., an angle sensor (125), an inertial measurement unit (IMU) (135)) provided in the wearable device (100) while the user (110) walks or performs exercise, and may evaluate the physical ability of the user (110) based on the measured movement information. For example, the gait index or exercise ability index (e.g., muscle strength, endurance, balance, exercise movement) of the user (110) may be estimated through the movement information of the user (110) measured by the wearable device (100). The physical ability measurement mode may include an exercise movement measurement mode for measuring the exercise movement of the user (110).

[0034] In various embodiments of the present disclosure, for convenience of explanation, a hip-type wearable device (100) as illustrated in FIG. 1 is described as an example, but is not limited thereto. As described above, the wearable device (100) may be worn on other body parts (e.g., upper arms, lower arms, hands, calves, feet) other than the waist and legs (particularly, thighs), and the shape and configuration of the wearable device (100) may vary depending on the body part on which it is worn.

[0035] According to one embodiment, the wearable device (100) may include a support frame for supporting the body of the user (110) when the wearable device (100) is worn on the body of the user (110) (e.g., leg support frame (50, 55) and waist support frame (20) of FIG. 3), a sensor module for obtaining sensor data including movement information about the body movement of the user (110) (e.g., leg movement, upper body movement) (e.g., sensor module (520) of FIG. 5A), a driving module (120) for generating a torque applied to the leg of the user (110) (e.g., driving module (35, 45) of FIG. 3), and a control module (130) for controlling the wearable device (100) (e.g., control module (510) of FIGS. 5A and 5B).

[0036] The sensor module may include an angle sensor (125) and an inertial measurement device (135). The angle sensor (125) may measure a rotation angle of a leg support frame of the wearable device (100) corresponding to a hip joint angle value of the user (110). The rotation angle of the leg support frame measured by the angle sensor (125) may be estimated to be a hip joint angle value (or leg angle value) of the user (110). The angle sensor (125) may include, for example, an encoder, a resolver, a home sensor, and / or a hall sensor. In one embodiment, the angle sensors (125) may be located near the right hip joint and the left hip joint of the user (110), respectively. The inertial measurement device (135) may include an acceleration sensor and / or an angular velocity sensor, and may measure a change in acceleration and / or angular velocity according to a movement of the user (110). The inertial measurement device (135) can measure, for example, the upper body movement value of the user (110) corresponding to the movement value of the waist support frame (or base body (base body (80) of FIG. 3)) of the wearable device (100). The movement value of the waist support frame measured by the inertial measurement device (135) can be estimated as the upper body movement value of the user (110).

[0037] In one embodiment, the control module (130) and the inertial measurement device (135) may be placed in the base body of the wearable device (100) (e.g., the base body (80) of FIG. 3). The base body may be positioned at the lumbar region (waist region) of the user (110) while the user (110) wears the wearable device (100). The base body may be formed or attached to the outside of the lumbar support frame of the wearable device (100). The base body may be mounted at the lumbar region of the user (110) to provide a cushioning feeling to the lumbar region of the user (110) and support the lumbar region of the user (110) together with the lumbar support frame.

[0038]

[0040] Referring to FIG. 2, the exercise management system (200) may include a wearable device (100) worn on a user's body, an electronic device (210), another wearable device (220), and a server (230). In one embodiment, the exercise management system (200) may omit at least one of these devices (e.g., another wearable device (220) or the server (230)) or may add one or more other devices (e.g., a dedicated controller device of the wearable device (100)).

[0041] 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.

[0042] 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 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., squats, split lunges, dumbbell squats, lunges and knee ups, stretching, etc.) to be exercised using the wearable device (100) through the electronic device (210) and / or an exercise intensity to be applied to the wearable device (100). The wearable device (100) may control the drive module of the wearable device (100) according to the exercise program selected by the user, and may acquire sensor data including information on the user's movement through the sensor module. The wearable device (100) may adjust the strength of the resistance force or the assistive force to be applied to the user according to the exercise intensity selected by the user. For example, the wearable device (100) can control the drive module to generate a resistance corresponding to the exercise intensity selected by the user.

[0043] In one embodiment, the wearable device (100) may be used to measure a user's physical ability in conjunction with an electronic device (210).

The electronic device (210) may analyze the sensor data received from the wearable device (100) to estimate the user's physical ability.

[0044] The electronic device (210) can communicate with the wearable device (100), 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, sensing status, error status). The electronic device (210) can receive sensor data acquired by a sensor of the wearable device (100) from the wearable device (100), and estimate the user's physical ability or exercise result based on the received sensor data. In one embodiment, when the user wears the wearable device (100) and exercises, the wearable device (100) can acquire sensor data including movement information of the user using the sensors, and transmit the acquired sensor data to the electronic device (210). The electronic device (210) can extract the user's movement value from the sensor data, and evaluate the user's exercise motion based on the extracted movement value. The electronic device (210) can provide the user with exercise motion measurement values ​​and exercise motion evaluation information for the user's exercise motion through a graphical user interface.

[0045] In one embodiment, the electronic device (210) may execute a program (e.g., an application) for controlling the wearable device (100), and the user may adjust the operation or setting values ​​(e.g., the torque intensity output from the driving module (e.g., the driving module (35, 45) of FIG. 3), the volume of the audio output from the sound output module (e.g., the sound output module (550) of FIGS. 5A and 5B), the brightness of the light unit (e.g., the light unit (85) of FIG. 3)) of the wearable device (100) through the program. The program executed in the electronic device (210) may provide a graphical user interface (GUI) for interaction with the user. The electronic device (210) may be a device of various forms. For example, the electronic device (210) may include, but is not limited to, a portable communication device (e.g., a smartphone), a computer device, an access point, a portable multimedia device, or a home appliance device (e.g., a television, an audio device, a projector device).

[0046] 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, or body mass index (BMI). The server (230) may receive exercise history information on exercise performed by the user from the electronic device (210) and store and manage the received exercise history information. The server (230) may provide various exercise programs or physical ability measurement programs that may be provided to the user to the electronic device (210).

[0047] According to one embodiment, the wearable device (100) and / or the electronic device (210) may be connected to another wearable device (220). The other wearable device (220) may be, for example, wireless earphones (222), a smartwatch (224), smartglasses (226), or a smartring (228), but is not limited to the aforementioned devices.

The electronic device (210) may estimate heart rate information of the user (e.g., current heart rate, maximum heart rate, average heart rate) based on the biosignal received from the smartwatch (224), and may provide the estimated heart rate information to the user. In one embodiment, the smart ring (226) can measure a bio-signal including the user's heart rate information and transmit the measured bio-signal to the electronic device (210) and / or the wearable device (100). The electronic device (210) can estimate the user's heart rate information (e.g., current heart rate, maximum heart rate, average heart rate) based on the bio-signal received from the smart ring (228) and provide the estimated heart rate information to the user.

[0048] In one embodiment, the user's exercise result information, physical ability information, and / or exercise motion evaluation information evaluated by the electronic device (210) may be transmitted to another 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 another 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).

[0050] In one embodiment, the electronic device (210) may present personalized exercise goals to the user in an exercise assistance mode. The personalized exercise goals may include exercise volume targets for each of the exercise types (e.g., strength training, balance training, aerobic training) that the user wishes to perform, as determined by the electronic device (210) and / or the server (230). When the server (230) determines the exercise volume targets, the server (230) may transmit information about the determined exercise volume targets to the electronic device (210). The electronic device (210) may present exercise volume targets for the exercise types of strength training, aerobic training, and balance training in a personalized manner according to the exercise program to be performed (e.g., squats, split lunges, lunge and knee-ups) and / or the user's physical characteristics (e.g., age, height, weight, BMI).

In this case, the drive module (35, 45) 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.

[0064] In one embodiment, the leg support frame (50, 55) can support the user's leg (e.g., thigh) when the wearable device (100) is worn on the user's leg. The leg support frame (50, 55) can transmit power (torque) generated from, for example, the driving module (35, 45) to the user's thigh, and the power can act as an external force applied to the movement of the user's leg. One end of the leg support frame (50, 55) can be connected to a joint member and rotated, and the other end of the leg support frame (50, 55) is connected to a thigh fastening part (1, 2), so that the leg support frame (50, 55) can support the user's thigh while transmitting the power generated from the driving module (35, 45) to the user's thigh. For example, the leg support frame (50, 55) can push or pull the user's thigh. The leg support frame (50, 55) can extend along the length direction of the user's thigh. The leg support frame (50, 55) can be folded to wrap around at least a portion of the user's thigh. The leg support frame (50, 55) can include a first leg support frame (55) for supporting the user's right leg and a second leg support frame (50) for supporting the user's left leg.

The thigh fastening parts (1, 2) may include a first thigh fastening part (2) for fixing the first leg support frame (55) to the user's right thigh and a second thigh fastening part (1) for fixing the second leg support frame (50) to the user's left thigh.

[0066] In one embodiment, the first thigh fastening part (2) may include a first cover, a first fastening frame, and a first strap, and the second thigh fastening part (1) may include a second cover, a second fastening frame, and a second strap. The first cover and the second cover may apply a torque generated from the driving module (35, 45) to the user's thigh. The first cover and the second cover may be disposed on one side of the user's thigh and may push or pull the user's thigh. The first cover and the second cover may be disposed on the front side of the user's thigh, for example. 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 the other end of the leg support frame (50, 55) as the center, and may include a curved surface corresponding to the user's thigh. One end of the first cover and the second cover may be connected to the fastening frame, and the other end may be connected to the strap.

[0067] 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 dislodged from the leg support frame (50, 55). 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.

[0068] 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).

[0070] FIGS. 5A and 5B are diagrams illustrating the configuration of a control system of a wearable device according to one embodiment.

[0071] Referring to FIG. 5A, a wearable device (100) may be controlled by a control system (500). The control system (500) may include a control module (510), a communication module (516), a sensor module (520), a driving module (530), an input module (540), and an audio output module (550). In one embodiment, the control system (500) may omit at least one of these components (e.g., an audio output module (550)), or may have one or more other components (e.g., a haptic module) added.

[0072] The drive module (530) may include a motor (534) capable of generating power (e.g., torque) and a motor driver circuit (532) for driving the motor (534). In the embodiment of FIG. 5A, a drive module (530) including one motor driver circuit (532) and one motor (534) is illustrated, but this is merely an example. Referring to FIG. 5B, as in the control system (500-1) illustrated in FIG. 5B, there may be a plurality of motor driver circuits (532, 532-1) and a plurality of motors (534, 534-1), respectively (e.g., two or more). A drive module (530) including a motor driver circuit (532) and a motor (534) may correspond to the first drive module (45) of FIG. 3, and a drive module (530-1) including a motor driver circuit (532-1) and a motor (534-1) may correspond to the second drive module (35) of FIG. 3. The description of each of the motor driver circuit (532) and the motor (534) described below may also be applied to the motor driver circuit (532-1) and the motor (534-1) illustrated in FIG. 5b.

The sensor module (520) may include sensor data including movement information of the user or movement information of the wearable device (100). The sensor module (520) may transmit the acquired sensor data to the control module (510). The sensor module (520) may include an inertial measurement device (522) and an angle sensor (e.g., a first angle sensor (524) and a second angle sensor (524-1)) as illustrated in FIG. 5B. The inertial measurement device (522) may measure movement values ​​of the user's upper body. For example, the inertial measurement device (522) may sense accelerations of the X-axis, Y-axis, and Z-axis and angular velocities of the X-axis, Y-axis, and Z-axis according to the movement of the user. The inertial measurement device (522) can be used to measure, for example, at least one of forward and backward tilt, left and right tilt, or rotation of the user's body. In addition, the inertial measurement device (522) can obtain movement values ​​(e.g., acceleration values ​​and angular velocity values) of a lumbar support frame (e.g., lumbar support frame (20) of FIG. 3) of the wearable device. The movement values ​​of the lumbar support frame can correspond to movement values ​​of the user's upper body.

[0074] The angle sensor can measure a hip joint angle value according to the movement of the user's legs. Sensor data that can be measured by the angle sensor can include, for example, information on the hip joint angle value of the right leg, the hip joint angle value of the left leg, and the movement direction of the legs. For example, the first angle sensor (524) of FIG. 5B can obtain the hip joint angle value of the user's right leg, and the second angle sensor (524-1) can obtain the hip joint angle value 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, a resolver, a home sensor, and / or a hall sensor. In addition, the angle sensor can obtain a movement value of the leg support frame of the wearable device (100). For example, the first angle sensor (524) can obtain a movement value of the first leg support frame (55), and the second angle sensor (524-1) can obtain a movement value of the second leg support frame (50). The movement value of the leg support frame can correspond to the hip joint angle value.

[0075] In one embodiment, the sensor module (520) may further include at least one of 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 user's biosignal, or a temperature sensor for measuring an ambient temperature.

[0076] The input module (540) can receive commands 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 module (540) can include an input component circuit. The input module (540) can include, for example, a key (e.g., a button) or a touch screen.

The wearable device (100) may convert the power of the battery to an operating voltage of each component of the wearable device (100) and supply the converted power to each component.

[0079] The drive module (530) can generate an external force applied to the user's leg under the control of the control module (510). The drive module (530) can generate a torque applied to the user's leg based on a control signal generated by the control module (510). The control module (510) can transmit the control signal to the motor driver circuit (532). The motor driver circuit (532) can control the operation of the motor (534) by generating a current signal (or voltage signal) corresponding to the control signal and supplying the current signal to the motor (534). In some cases, the current signal may not be supplied to the motor (534). When the motor (534) is driven by supplying a current signal to the motor (534), the motor (534) can generate a torque for an assistive force that assists the movement of the user's leg or a resistive force that hinders the movement of the leg.

According to one embodiment, the processor (512) may include 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 processing unit (NPU), an image signal processor, a sensor hub processor, or a communication processor) that can operate independently or together therewith. The auxiliary processor may be implemented separately from the main processor or as part of it.

[0082] The memory (514) can store various data used by at least one component (e.g., processor (512)) of the control module (510). The data can include, for example, input data or output data for software, sensor data, and commands related thereto. The memory (514) can include volatile memory or non-volatile memory (e.g., RAM, DRAM, SRAM).

[0083] The communication module (516) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the control module (510) and other components of the wearable device (100) or an external electronic device (e.g., the electronic device (210) or another wearable device (220) of FIG. 2), and the performance of communication through the established communication channel. The communication module (516) may include a communication circuit for performing a communication function. The communication module (516) may, for example, receive a control signal from an electronic device (e.g., the electronic device (210)) and transmit sensor data acquired by the sensor module (520) to the electronic device. According to one embodiment, the communication module (516) may operate independently from the processor (512) and may include one or more communication processors (not shown) that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (516) may include a wireless communication module (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) and / or a wired communication module. Any of these communication modules may communicate with other components of the wearable device (100) and / or external electronic devices via a short-range communication network such as, for example, Bluetooth, wireless fidelity (Wi-Fi), or infrared data association (IrDA), or a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN).

[0084] In one embodiment, the control system (500, 500-1) may further include a haptic module (not shown). The haptic module may provide tactile feedback to a user under the control of the processor (512). The haptic module may convert an electrical signal into a mechanical stimulus (e.g., vibration or movement) or an electrical stimulus that a user may perceive through a tactile or kinesthetic sense. The haptic module may include a motor, a piezoelectric element, or an electrical stimulation device. In one embodiment, the haptic module may be located in at least one of the base body (e.g., the base body (80)), the first thigh fastening portion (2), or the second thigh fastening portion (1).

[0085]

[0090]

[0093] 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 commands or data received from another component (e.g., communication module (730)) in the memory (720), process the commands or data stored in the memory (720), and store result data in the memory (720).

[0094] According to one embodiment, the processor (710) may include 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 therewith.

[0100]

[0101] FIG. 8 is a flowchart of a method for outputting a first alarm based on a first location of an electronic device, according to one embodiment.

[0102] The following operations 810 to 850 may be performed by an electronic device (e.g., the wearable device (100) of FIG. 1 or the electronic device (210) of FIG. 2). The electronic device may include at least one processor (e.g., the processor (512) of FIG. 5A or the processor (710) of FIG. 7) and a memory (e.g., the memory (514) of FIG. 5 or the memory (720) of FIG. 7) that stores instructions. For example, the electronic device may be a user terminal physically separated from the wearable device. For example, the electronic device may be a control module included in the wearable device (e.g., the control module (130) of FIG. 1, the control module (510) of FIGS. 5A and 5B).

[0103] According to one embodiment, operations 810 to 850 may be performed while the wearable device (e.g., the wearable device (100) of FIG. 1) operates in a first operation mode. The first operation mode may be a first exercise program among a plurality of exercise programs that may be performed by the wearable device. For example, the first operation mode may be a walking assistance mode in which the wearable device assists the user's walking. For example, the first operation mode may be an exercise assistance mode in which the wearable device enhances the exercise effect of the user.

[0104] In operation 810, the electronic device can determine a first location of the electronic device. The first location may be a global location of the electronic device. For example, the electronic device can determine the first location of the electronic device using a global navigation satellite system (GNSS) communication module. For example, the GNSS communication module can determine the first location of the electronic device using a global positioning system (GPS), assisted GPS (A-GPS), Galileo, global navigation satellite system (GLONASS), BeiDou, quasi-zenith satellite system (QZSS), or Indian regional navigation satellite system (IRNSS).

[0105] In one embodiment, the first location may further include orientation information of the electronic device. For example, the electronic device may determine the attitude of the electronic device using an IMU and generate orientation information based on the determined attitude. The orientation information may be the orientation of the electronic device determined based on a preset direction (e.g., true north).

[0106] In operation 820, the electronic device may transmit information about a first location of the electronic device to a first server. For example, the first server may be a server that provides terrain information of the ground. The terrain information of the ground may include contour lines and / or slope of the ground.

[0107] In operation 830, the electronic device may receive first topographic information associated with a first location from a first server. The first topographic information may be topographic information of an area surrounding the first location. For example, the first topographic information may include contour lines and / or slopes of the surrounding area. The first topographic information may include information regarding the map scale. The first topographic information is described in detail below with reference to FIG. 9.

[0108] In operation 840, the electronic device may determine a first target location having a first target altitude having a preset altitude difference from a first altitude of the first location using the first terrain information. For example, the preset altitude difference may be a minimum altitude difference provided by the first terrain information (e.g., 5 meters or 10 meters). For example, if the first altitude of the first location is 140 meters and the preset altitude difference is 10 meters, the first target altitude may be 130 meters or 150 meters. According to one embodiment, the first target location may be one or more of a plurality of locations having the first target altitude.

[0109] For example, the first target position may be a position having a first target altitude and corresponding to a preset direction (e.g., due north, due east, due south, or due west) relative to the first position. A method for determining the first target position based on the preset direction is described in detail below with reference to FIG. 9.

[0110] For example, if the electronic device can identify a path (or road) appearing on the first terrain information (910), the electronic device can determine a location among the identified paths having a first target altitude as the first target location.

[0111] For example, the first target location may be a location having a first target altitude and corresponding to a target path between the first location and the destination location. A method for determining the first target location based on the target path is described in detail below with reference to FIGS. 10 and 11.

[0112] For example, the first target position may be determined based on a direction determined using a past movement path. A method for determining the first target position based on a past movement path is described in detail below with reference to FIGS. 12 and 13.

[0113] In operation 850, the electronic device may output a first alarm based on a first distance between a first location and a first target location. The electronic device may calculate the first distance between the first location and the first target location. For example, the electronic device may calculate the first distance between the first location and the second target location using a map scale.

[0114] According to one embodiment, the electronic device can determine whether the first distance exceeds a set threshold distance. For example, the threshold distance may be preset based on user information. The user information may include at least one of the user's age, physical condition, injury level, or disability level. The threshold distance may be determined differently depending on the user's age. The threshold distance may be determined to be longer as physical ability (e.g., muscle strength or balance) decreases. For example, if the user is 60 years of age or older, the threshold distance may be determined to be 81.30 meters, and if the user is under 60 years of age, the threshold distance may be determined to be 21.46 meters.

[0115] If the first distance exceeds the threshold distance, the direction toward the first target location may be determined to have terrain that is stable for the user to navigate. For example, as the first distance increases, the absolute value of the first slope calculated based on the first distance and the preset altitude difference may decrease. The smaller the absolute value of the first slope, the more stable the terrain may be for the user to navigate.

[0116] In one embodiment, the electronic device may output a first alarm if the first distance does not exceed a set threshold distance. For example, the first alarm may be a set audio signal. For example, the first alarm may be a set haptic vibration signal. For example, the first alarm may be a set screen signal.

[0117] A user wearing a wearable device can determine whether the surrounding area is suitable for exercise through a first alarm. For example, if the user determines that continued exercise is difficult at the current location, the user can input a control command to change the operating mode of the wearable device using an electronic device or the wearable device. For example, if the user determines that continued exercise is possible at the current location, the user can input a control command to maintain the operating mode of the wearable device using an electronic device or the wearable device.

[0118] According to one embodiment, after the electronic device outputs the first alarm, the operating mode of the wearable device may be changed from the first operating mode to the second operating mode. For example, the second operating mode may be an operating mode in which no torque is output by the wearable device. For example, the second operating mode may be an operating mode in which the reverse drivability of the motor of the wearable device is maximized. When the first terminal and the second terminal of the motor are not electrically connected, the reverse drivability of the motor may be maximized. The operating mode in which the reverse drivability of the motor of the wearable device is maximized may be a freestyle mode. The freestyle mode may be a mode in which the motor is not electrically connected to the motor driver circuit. When the wearable device operates in the freestyle mode, the user may only feel the resistance due to the friction of the gears connected between the shaft of the motor and the leg support frame, and may not feel the assisting force or resistance due to the torque output by the motor. As the wearable device is controlled in the second operating mode, the user may be able to pass through the terrain stably.

[0119]

[0120] FIG. 9 illustrates target locations determined using first topographic information associated with a first location of an electronic device, according to one embodiment.

[0121] According to one embodiment, an electronic device (e.g., a wearable device (100) of FIG. 1 or an electronic device (210) of FIG. 2) may receive first topographic information (910) associated with a first location from a first server. For example, the first topographic information (910) may include contour lines for an area surrounding the first location (902).

[0122] The electronic device may determine a first altitude of the first location (902) based on the first terrain information (910). For example, if the first location (902) is located on a first contour line, the first altitude of the first location (902) may be determined as the altitude of the first contour line. For example, if the first location (902) is located between a first contour line and a second contour line, the first altitude of the first location (902) may be determined based on the altitude of the first contour line and the altitude of the second contour line.

[0123] If the first altitude of the first location (902) is 140 meters and the preset altitude difference is 10 meters, the first target altitude may be 130 meters or 150 meters. A plurality of target locations (912, 914, 916, 918) having the first target altitude and corresponding to preset directions (e.g., due north, due east, due south, and due west) with respect to the first location (902) may be determined. The resolution or number of preset directions with respect to the first location (902) may vary depending on the embodiment. The electronic device may calculate distances (922, 924, 926, 928) to the plurality of target locations (912, 914, 916, 918) from the first location (902), respectively.

[0124] According to one embodiment, the electronic device may output a first alarm if any one of the calculated distances (922, 924, 926, 928) is determined to be less than a threshold distance.

[0126] FIG. 10 is a flowchart of a method for determining a target location based on a target path between a first location and an arrival location, according to one embodiment.

[0127] According to one embodiment, operations 1010 to 1030 below may be performed by an electronic device (e.g., the wearable device (100) of FIG. 1 or the electronic device (210) of FIG. 2). For example, operations 1010 and 1020 may be performed after operation 830 described above with reference to FIG. 8 is performed. Operation 840 may be performed after operation 1020 is performed. Operation 840 may include operation 1030.

[0128] In operation 1010, the electronic device may transmit information about the first location and the destination location to a second server. For example, the destination location may be the user's final destination. The second server may determine an optimal route between the first location and the destination location as a target route and transmit information about the target route to the electronic device.

[0129] In one embodiment, if the first server is a server capable of determining an optimal path, the second server may be the first server.

[0130] In operation 1020, the electronic device may receive information about a target path between a first location and a destination location from a second server.

[0131] In operation 1030, the electronic device may determine a first target location based on a target path. For example, the electronic device may indicate the target path on first terrain information (e.g., first terrain information (910) of FIG. 9) and determine a location having a first target altitude among the target paths as the first target location.

[0132]

[0133] FIG. 11 illustrates a target location determined based on a target path according to one embodiment.

[0134] According to one embodiment, an electronic device (e.g., a wearable device (100) of FIG. 1 or an electronic device (210) of FIG. 2) may receive information about a target path (1110) between a first location (902) and a destination location (1102) from a second server.

[0135] The electronic device can display a target path (1110) on the first terrain information (910) and determine a location having a first target altitude (e.g., 130 meters) among the target paths (1110) as a first target location (1112). The electronic device can calculate a first distance (1122) between the first location (902) and the first target location (1112).

[0136]

[0137] FIG. 12 is a flowchart of a method for determining a target location based on a movement path of an electronic device, according to one embodiment.

[0138] According to one embodiment, operations 1210 and 1220 below may be performed by an electronic device (e.g., the wearable device (100) of FIG. 1 or the electronic device (210) of FIG. 2). For example, operation 1210 may be performed after operation 830 described above with reference to FIG. 8 is performed. Operation 840 may be performed after operation 1210 is performed. Operation 840 may include operation 1220.

[0139] In operation 1210, the electronic device may obtain a movement path of the electronic device. For example, the movement path may be positions of the electronic device obtained over a preset period of time.

[0140] In operation 1220, the electronic device can determine a first target location based on the movement path. The electronic device can determine a movement direction (or movement vector) based on the movement path. The electronic device can determine a location having a first target altitude among the movement directions as the first target location.

[0141]

[0142] FIG. 13 illustrates a target location determined based on a movement path according to one embodiment.

[0143] According to one embodiment, an electronic device (e.g., the wearable device (100) of FIG. 1 or the electronic device (210) of FIG. 2) can obtain a movement path (1302) of the electronic device. For example, the movement path (1302) can be a path between a starting location (1301) and a first location (902). The electronic device can determine a movement direction (1310) based on the movement path (1302). The electronic device can determine a location having a first target altitude among the movement directions (1310) as a first target location (1312). The electronic device can calculate a first distance (1310) between the first location (902) and the first target location (1312).

[0144]

[0145] FIG. 14 is a flowchart of a method for outputting a first alarm corresponding to a first slope calculated based on a first distance between a first location and a first target location, according to one embodiment.

[0146] According to one embodiment, operations 1410 and 1420 below may be related to operation 850 described above with reference to FIG. 8. For example, operation 850 may include operations 1410 and 1420. Operations 1410 and 1420 may be performed by an electronic device (e.g., the wearable device (100) of FIG. 1 or the electronic device (210) of FIG. 2).

[0147] In operation 1410, the electronic device may determine a first slope based on a first distance between a first location and a first target location. Since the elevation difference between the first location and the first target location has a preset elevation difference (e.g., 5 meters or 10 meters), the first slope may be determined based on the first distance and the preset elevation difference. For example, the determined first slope may be an absolute value.

[0148] In operation 1420, the electronic device may output a first alarm corresponding to the first slope. The electronic device may determine whether the first slope is less than or equal to a first threshold slope. The first threshold slope may be preset. The first threshold slope may be set differently depending on the user of the wearable device. The electronic device may determine not to output the first alarm if the first slope is less than or equal to the first threshold slope. The electronic device may determine to output the first alarm if the first slope exceeds the first threshold slope.

[0149] For example, the electronic device can output the first alarm by outputting a set audio using an audio output module (e.g., the audio output module (750) of FIG. 7). For example, the electronic device can output the first alarm by outputting a set tactile pattern using a haptic module. For example, the electronic device can output the first alarm by outputting a set message (or screen) using a display module (e.g., the display module (740) of FIG. 7).

[0150]

[0151] FIG. 15 is a flowchart of a method for determining whether to output a first alarm based on a first slope and user information, according to one embodiment.

[0152] According to one embodiment, operations 1510 and 1520 below may be performed by an electronic device (e.g., the wearable device (100) of FIG. 1 or the electronic device (210) of FIG. 2). Operation 1510 may be performed before operation 810 described above with reference to FIG. 8 is performed. Operation 1520 may be related to operation 850 described above with reference to FIG. 8. For example, operation 850 may include operation 1520.

[0153] In operation 1510, the electronic device may obtain user information of the user. For example, the user information may include at least one of the user's age, user's physical condition, injury level, or disability level.

[0154] At step 1520, the electronic device may determine whether to output a first alarm based on the first slope and user information. Step 1520 is described in detail below with reference to FIG. 16.

[0155]

[0156] FIG. 16 is a flowchart of a method for determining whether to output a first alarm based on a first threshold slope determined based on user information, according to one embodiment.

[0157] According to one embodiment, operations 1610 to 1630 below may be related to operation 1520 described above with reference to FIG. 15. For example, operation 1520 may include operations 1610 to 1630. Operations 1610 to 1630 may be performed by an electronic device (e.g., the wearable device (100) of FIG. 1 or the electronic device (210) of FIG. 2).

[0158] In operation 1610, the electronic device may determine a first threshold slope corresponding to user information (e.g., the user's age). The first threshold slope may be determined differently depending on the user's age. The lower the user's physical ability (e.g., muscle strength or balance), the lower the first threshold slope may be determined. For example, if the user is 60 years of age or older, the first threshold slope may be determined to be 7°, and if the user is under 60 years of age, the first threshold slope may be determined to be 25°.

[0159] At operation 1620, the electronic device may determine whether the first slope is less than or equal to a first threshold slope.

[0160] At operation 1630, the electronic device may determine to output a first alarm if the first slope exceeds a first threshold slope.

[0161]

[0162] FIG. 17 is a flowchart of a method for changing an operation mode of a wearable device from a first operation mode to a second operation mode based on a control command for controlling an acquired wearable device, according to one embodiment.

[0163] According to one embodiment, operations 1710 and 1720 below may be performed by an electronic device (e.g., the wearable device (100) of FIG. 1 or the electronic device (210) of FIG. 2). For example, operations 1710 and 1720 may be performed after operation 850 described above with reference to FIG. 8 is performed.

[0164] In operation 1710, the electronic device may obtain a control command for controlling the operation of a wearable device connected to the electronic device. According to one embodiment, the first alarm may be a message requesting a response from the user to the first alarm. The message may include one or more graphical user interfaces (GUIs) capable of receiving user input. For example, the one or more GUIs may include a first GUI indicating consent to changing the operation mode of the wearable device and / or a second GUI indicating rejection.

[0165] The electronic device can receive a control command from the user via the user interface to change the operating mode of the wearable device. For example, if the user touches a first GUI indicating consent to changing the operating mode, the electronic device can obtain a first control command corresponding to the first GUI. For example, if the user touches a second GUI indicating rejection of changing the operating mode, the electronic device can obtain a second control command corresponding to the second GUI.

[0166] In one embodiment, the electronic device may consider a preset input received if no input is received for a preset period of time, even if no explicit input is received from the user. For example, the electronic device may preset a first control command or a second control command as received, depending on the user's settings, if no input is received for a preset period of time.

[0167] In operation 1720, the electronic device may change the operating mode of the wearable device from the first operating mode to the second operating mode based on the control command. For example, if the control command is a first control command corresponding to the first GUI indicating consent to change the operating mode, the operating mode of the wearable device may be changed from the first operating mode to the second operating mode.

[0168] To prevent the wearable device from abruptly changing its operating mode, the operating mode may transition from a first operating mode to a second operating mode for a preset period of time. For example, first values ​​of control parameters in the first operating mode may gradually change to second values ​​in the second operating mode. The electronic device may output audio indicating the change in operating mode for a preset period of time.

[0169] The first operation mode may be the first exercise program among multiple exercise programs that can be performed by the wearable device. For example, the first operation mode may be a walking assistance mode in which the wearable device assists the user's walking. For example, the first operation mode may be an exercise assistance mode in which the wearable device enhances the user's exercise effect.

[0170] The second operating mode may be an operating mode in which no torque is output by the wearable device. For example, the second operating mode may be an operating mode in which the reverse drivability of the motor of the wearable device is maximized.

[0171]

[0172] FIG. 18 is a flowchart of a method for outputting a second alarm based on a second location of an electronic device, according to one embodiment.

[0173] According to one embodiment, operations 1810 to 1840 below may be performed by an electronic device (e.g., the wearable device (100) of FIG. 1 or the electronic device (210) of FIG. 2). For example, operations 1810 to 1840 may be performed after operation 1720 described above with reference to FIG. 8 is performed.

[0174] In operation 1810, a second position of the electronic device may be determined. As the user moves, the determined position of the electronic device may change. The description of operation 1810 may be replaced with the description of operation 810 described above with reference to FIG. 8.

[0175] In one embodiment, the electronic device may transmit the second location to the first server if the second location is not included in the first geographic information. The electronic device may receive second information associated with the second location from the first server.

[0176] In operation 1820, the electronic device may determine a second target location having a second target altitude having a preset altitude difference from the second altitude of the second location. The description of the method for determining the second target location may be similarly applied to the description of the method for determining the first target location. For example, the description of operation 1820 may be similarly applied to the description of operation 840 of FIG. 8, the description of operation 1030 of FIG. 10, or the description of operation 1220 of FIG. 12.

[0177] In operation 1830, the electronic device may output a second alarm based on a second distance between the second location and the second target location. The description of the method for calculating the second distance may be replaced with the description of the method for calculating the first distance described above.

[0178] In one embodiment, the electronic device may determine whether the second distance exceeds a set threshold distance. If the second distance exceeds the threshold distance, the direction toward the second target location may be determined to have stable terrain for the user to move over.

[0179] In one embodiment, the electronic device may output a second alarm when the second distance exceeds a set threshold distance. For example, the second alarm may be a set audio signal. For example, the second alarm may be a set haptic vibration. For example, the second alarm may be a set screen.

[0180] A user wearing a wearable device can use a second alarm to determine whether the surrounding area is suitable for exercise. For example, if the user determines that exercise can be resumed from the current location, the user can input a control command to change the operating mode of the wearable device via the electronic device or the wearable device. For example, if the user determines that exercise cannot be resumed from the current location, the user can input a control command to maintain the operating mode of the wearable device via the electronic device or the wearable device.

[0181] The electronic device can receive a control command from the user via the user interface to change the operating mode of the wearable device. For example, if the user touches a first GUI indicating consent to changing the operating mode, the electronic device can obtain a first control command corresponding to the first GUI. For example, if the user touches a second GUI indicating rejection of changing the operating mode, the electronic device can obtain a second control command corresponding to the second GUI.

[0182] In one embodiment, the electronic device may consider a preset input received if no input is received for a preset period of time, even if no explicit input is received from the user. For example, the electronic device may preset a first control command or a second control command as received, depending on the user's settings, if no input is received for a preset period of time.

[0183] At operation 1840, the electronic device may change the operating mode of the wearable device from the second operating mode to the first operating mode.

[0184] In one embodiment, the electronic device may change the operating mode of the wearable device from the second operating mode to the first operating mode after outputting the second alarm. For example, if the control command is a first control command corresponding to the first GUI indicating consent to change the operating mode, the operating mode of the wearable device may be changed from the second operating mode to the first operating mode.

[0185] To prevent the wearable device from abruptly changing its operating mode, the operating mode may transition from a second operating mode to a first operating mode for a preset period of time. For example, the second values ​​of control parameters in the second operating mode may gradually change to the first values ​​in the first operating mode. The electronic device may output audio indicating the change in operating mode for a preset period of time.
