[0024]

[0025] FIG. 1 is a drawing for explaining an overview of a wearable device worn on a user's body according to various embodiments.

[0026] 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 embodiments, 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.

[0027] 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'.

[0028] In one embodiment, the wearable device (100) may operate in a walking assistance mode to assist the walking of the 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 the 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 user with abnormal walking habits or walking posture.

[0029] 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 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 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.

[0030] 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 that the user (110) performs 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 that matches the appropriate physical condition (e.g., heart rate) of the user (110) while performing the exercise may be guided to the user.

[0031] 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 (125)) or an inertial measurement unit (IMU) (135)) 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. For example, the gait index (e.g., number of steps, total walking distance, stride) or the exercise ability index (e.g., muscle strength, exercise endurance, postural balance) of the user (110) may be estimated through the movement information of the user (110) measured by the wearable device (100).

[0032] 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 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.

[0033] The wearable device (100) may include a support frame (e.g., a waist support frame (20) of FIGS. 3 and 4) 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 (120) for generating a torque applied to the legs of the user (110) (e.g., a first drive module (45) and a second drive module (35) of FIG. 3), a torque transmission frame for transmitting the torque generated by the drive module (120) to the legs of the user (110) (e.g., a first torque transmission frame (55) and a second torque transmission frame (50) of FIG. 3), a sensor circuit including one or more sensors for obtaining sensor data including movement information on the body movement of the user (110) (e.g., leg movement, upper body movement), and a control circuit (130) for controlling the operation of the wearable device (100) (e.g., a control circuit (510) of FIG. 5). there is.

[0034] In one embodiment, the wearable device (100) may include an angle sensor (125) and an inertial sensor (135). The angle sensor (125) may measure a rotational angle of a torque transmission frame of the wearable device (100) corresponding to a hip joint angle of the user (110). The angle sensor (125) may include, for example, an encoder and / or a hall sensor. In one embodiment, the angle sensor (125) may be positioned near a motor included in the drive module (120) that is directly or indirectly connected to the torque transmission frame. The inertial sensor (135) may include an acceleration sensor and / or an angular velocity sensor, and may measure changes in acceleration and / or angular velocity according to movements of the user (110). The inertial sensor (135) can measure, for example, a movement value of a waist support frame (e.g., waist support frame (20) of FIG. 3) or a base body (e.g., base body (80) of FIG. 3) of a wearable device (100). The movement value of the waist support frame or base body measured by the inertial sensor (135) can correspond to a waist movement value (or upper body movement value) of a user (110).

[0035] In one embodiment, the control circuit (130) and the inertial sensor (135) may be placed within a base body of the wearable device (100) (e.g., the base body (80) of FIG. 3). The base body may be positioned at the waist area of ​​the user (110) while the user (110) is wearing the wearable device (100). The base body may be formed or attached to the outside of the waist support frame of the wearable device (100). The base body may support the lumbar region of the user (110).

[0036]

[0040] 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 (e.g., a driving module (120) of FIG. 1) 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.

[0041] The wearable device (100) can transmit sensor data measured through a sensor (e.g., an angle sensor (125) or an inertial sensor (135) of FIG. 1) and device information (e.g., charging status information, operation mode information, setting information) of the wearable device (100) to the electronic device (210) and / or the 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).

[0062] 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 forward direction may be a direction corresponding to the user's front direction or flexion motion of the legs, and the backward direction may be a direction corresponding to the user's back direction or extension motion of the legs.

[0063] The first driving module (45) may include a first actuator and a first joint member, and the second driving module (35) may include a second actuator and a second joint member. 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.

[0064] 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. In one embodiment, 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.

[0065] 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.

[0066] 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 user's leg movement. 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.

[0067] 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).

[0068] In one embodiment, the first thigh fastening unit (2) may include a first cover, a first fastening frame, and a first strap, and the second thigh fastening unit (1) may include a second cover, a second fastening frame, and a second strap. 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.

[0069] 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.

[0070] 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).

[0072] FIG. 5 is a diagram illustrating configurations of a wearable device according to various embodiments.

[0073] Referring to FIG. 5, the wearable device (100) may include a control circuit (510), a communication circuit (516), one or more sensors (e.g., an inertial sensor (522, a first angle sensor (524), a second angle sensor (524-1)), a drive module (530, 530-1), an input circuit (540), an audio output circuit (550) including a speaker, a haptic circuit (560), and a lighting circuit (570).

In the embodiment of FIG. 5, two drive modules are illustrated, but this is merely an example, and there may be one drive module, or three or more drive modules. The drive module (530) including the motor driver circuit (532) and the motor (534) may correspond to the first drive module (45) of FIG. 3, and the drive module (530-1) including the motor driver circuit (532-1) and the motor (534-1) may correspond to the second drive module (35) of FIG. 3.

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 a movement value (e.g., angle) of the first torque transmission frame of the wearable device (e.g., the first torque transmission frame (55) of FIG. 3), and the hip joint angle of the left leg sensed by the second angle sensor (524-1) may correspond to a movement value (e.g., angle) of the second torque transmission frame of the wearable device (e.g., the second torque transmission frame (50) of FIG. 3).

[0078] In one embodiment, the first angle sensor (524) and the second angle sensor (524-1) may sense the knee joint angle or the ankle joint angle according to the user's leg movement.

[0079] In one embodiment, the processor (512) can determine the angular velocity of the first torque transfer frame by differentiating the angular change over time of the first torque transfer frame sensed by the first angle sensor (524), and can determine the angular velocity of the second torque transfer frame by differentiating the angular change over time of the second torque transfer frame sensed by the second angle sensor (524-1).

[0080] 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.

[0081] The input circuit (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 circuit (540) can include, for example, keys (e.g., buttons) and / or a touch screen.

[0082] The audio output circuit (550) can output an audio signal to the outside of the wearable device (100). The audio output circuit (550) can include a speaker that plays a guide audio signal (e.g., a driving start sound, an operation error notification sound), music content, or a guide voice.

[0083] In one embodiment, the wearable device (100) may further include a battery (not shown) for supplying power to each component of the wearable device (100) and a power management integrated circuit (PMIC) (not shown) for controlling the power supply. The power management integrated circuit may convert power from the battery to an operating voltage of each component of the wearable device (100) and supply the converted power to each component.

[0084] 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 (534, 534-1) can generate an assistive force that assists the user's leg movement or a resistive force that impedes the leg movement when a current signal is supplied to the motor (534, 534-1) and the motor is driven.

[0085] The control circuit (510) controls the overall operation of the wearable device (100) and can generate control signals for controlling each component of the wearable device (100). The control circuit (510) may include a processor (512) and a memory (514).

[0086] The processor (512) may, for example, execute software to control at least one other component (e.g., a hardware or software component) of the wearable device directly or indirectly connected to the processor (512), and may perform various data processing or calculations.

The processor (512) may also be implemented as a system on chip (SoC) or an integrated circuit (IC) that performs processing. The auxiliary processor may be implemented separately from the main processor or as a part thereof.

[0088] Each "processor" in this disclosure may include a processing circuit or may include multiple processors. For example, as used in this disclosure, including in the claims, the term "processor" may encompass various processing circuits including at least one processor, wherein one or more processors may be individually and / or collectively configured to perform various functions described herein in a distributed manner. When "processor," "at least one processor," and "one or more processors" are described herein as being configured to perform multiple functions, these terms include, but are not limited to, situations where one processor performs some of the recited functions and another processor performs other of the recited functions, and situations where a single processor may perform all of the recited functions. Furthermore, the one or more processors may include a combination of processors that perform various recited / disclosed functions, for example, in a distributed manner. The one or more processors may execute program instructions to achieve or perform various functions.

[0089] The memory (514) can store various data used by at least one component (e.g., the processor (512)) of the control circuit (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 at least one instruction executable by the processor (512). The memory (514) can include one or more memories, and instructions for controlling the processor (512) to perform operations of the wearable device (100) described in the present disclosure can be stored in one memory or can be divided and stored in multiple memories. The memory (514) can include a volatile memory or a non-volatile memory.

[0090] The communication circuit (516) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the control circuit (510) and other components of the wearable device (100) or an external electronic device (e.g., the electronic device (210) of FIG. 2 or another wearable device (220)), and the performance of communication through the established communication channel. The communication circuit (516) may, for example, transmit sensor data acquired by a sensor to an external electronic device (e.g., the electronic device (210) of FIG. 2) and receive a control signal from the external electronic device. In one embodiment, the communication circuit (516) may include one or more communication processors that operate independently from the processor (512) and support direct (e.g., wired) communication or wireless communication. In one embodiment, the communication circuit (516) may include a wireless communication circuit (e.g., a cellular communication circuit, a short-range wireless communication circuit, or a global navigation satellite system (GNSS) communication circuit) and / or a wired communication circuit. The wireless communication circuitry may communicate with other components of the wearable device (100) and / or external devices via, for example, Bluetooth, WiFi (wireless fidelity), IrDA (infrared data association), a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a local area network (LAN) or a wide area network (WAN).

[0091] The haptic circuit (560) can provide haptic feedback to a user under the control of the processor (512). The haptic circuit (560) can include one or more haptic actuators. The haptic actuators can include, for example, a piezo actuator, a bander type actuator, and / or a vibration motor-based actuator. The haptic actuators can be one or more. In one embodiment, the haptic actuator can be located in at least one of a base body (e.g., the base body (80) of FIG. 3), a torque transmission frame (e.g., the first torque transmission frame (75) of FIG. 3, the second torque transmission frame (70)), and a thigh fastening part (e.g., the first thigh fastening part (2) of FIG. 3, the second thigh fastening part (1)) of the wearable device (100).

[0092] The lighting circuit (570) may be a circuit included in a lighting module (e.g., the lighting module (85) of FIG. 3). The lighting circuit (570) may include a light source element (572) that outputs light, and a circuit element (574) having an element value corresponding to the color of the base body of the wearable device (100) (e.g., the base body (80) of FIG. 3).

[0093] The light source element (572) may include, for example, an LED. The processor (512) may determine the color of light and / or the light output pattern output by the light source element (572) depending on the system status or operation mode of the wearable device (100). For example, when the battery charge of the wearable device (100) is below a reference level, the processor (512) may control the light source element (572) to blink red light at a preset cycle. When the wearable device (100) is attempting pairing for a Bluetooth communication connection, the processor (512) may control the light source element (572) to blink blue light at a preset cycle. The processor (512) can control the light source element (572) to output green light when the wearable device (100) operates in a walking assistance mode, and can control the light source element (572) to output orange light when the wearable device (100) operates in a movement assistance mode. The color and / or output pattern of the light output by the light source element (572) depending on the system status or operation mode of the wearable device (100) is not limited to the examples described above.

[0094] The circuit element (574) may include at least one of a passive element and / or an active element, for example, a resistor element, a capacitance element, an inductance element, a transistor element, and an integrated circuit element. When the base body of the wearable device (100) has a first color, the circuit element (574) may have a first element value, and when the base body has a second color different from the first color, the circuit element (574) may have a second element value different from the first element value. For example, it is assumed that the circuit element (574) is a resistor element. In this case, when the color of the base body is black, a resistor element with a resistance value of 1000 ohms may be placed (or mounted) in the lighting circuit (570), and when the color of the base body is white, a resistor element with a resistance value of 5000 ohms may be placed (or mounted) in the lighting circuit (570).

[0095] The processor (512) can measure (or sense) an electric signal value that depends on the element value of the circuit element (574), and control the color value of light applied to the light source element (572) based on the measured electric signal value. The processor (512) can recognize the element value of the circuit element (574) based on the measured electric signal value. The processor (512) can measure the current through the port to which the circuit element (574) is connected when a reference voltage is applied to the circuit element (574), and can recognize the element value (e.g., resistance value) of the circuit element (574) according to Ohm's law. The processor (512) can also directly measure the element value of the circuit element (574).

[0096] The processor (512) selects target color control data to be applied to the light source element (572) based on an electric signal value that depends on the element value of the circuit element (574) among the color control data corresponding to different colors of the base body of the wearable device (100), and controls the color value of light applied to the light source element (572) according to the selected target color control data. The color control data may be included in firmware (e.g., LED firmware) that controls the operation of the light source element (572) according to, for example, the system status and / or the operation mode of the wearable device (100). The color control data may define a color attribute of the color of light output by the light source element (572). The color control data may be, for example, table data in which color values ​​to be applied to the light source element (572) according to the system status and / or the operation mode are defined, but is not limited thereto. Color control data corresponding to each color of the base body may exist. When the element value of the circuit element (574) is recognized, the processor (512) selects color control data corresponding to the recognized element value within the firmware, and can control the color value of light applied to the light source element (572) according to the selected color control data. If the color control data applied to the light source element (572) are different, light with different color values ​​may be output from the light source element (572) even if the system status or operation mode of the wearable device (100) is the same.

[0097] In general, human eyes have differences in color perception depending on the surrounding background color even if the color is the same. Therefore, when the colors of the base bodies of the wearable device (100) are different and the light source element (572) outputs light with the same color value, a difference in the color perception perceived by a person may occur due to the color of the base body even though the color is the same. For example, when the color of the light output from the light source element (572) is blue, the color may be perceived as greenish when the base body is white compared to when the base body is black. In order to provide the user with the same color perception as much as possible even when the color of the base body is different, the wearable device (100) can identify the color of the base body by recognizing the element value of the circuit element (574) having the element value corresponding to the color of the base body. The memory (514) stores a plurality of color control data corresponding to each color of the identified base body, each element value of the recognized circuit element (574), or each electrical signal value dependent on the element value of the circuit element (574), and the processor (512) can select target color control data to be applied to the light output of the light source element (572) based on the electrical signal value dependent on the element value of the circuit element (574) among the plurality of color control data. The electrical signal value dependent on the element value of the circuit element (574) measured by the processor (512) can correspond to a specific element value of the circuit element (574) and a specific color of the base body.

[0098] The wearable device (100) identifies the color of the base body that acts as a background color for the color of light output from the light source element (572) based on the element value of the circuit element (574), and uses target color control data defined to provide optimal color sensation in the color of the identified base body, thereby enabling the originally intended color sensation of light to be realized without the constraints of the external color of the wearable device (100).

[0099] According to one embodiment, a wearable device (100) may include a motor (534, 534-1) for generating a torque applied to the body of a user wearing the wearable device (100), a torque transmission frame for transmitting the generated torque to the user's leg (e.g., a first torque transmission frame (55), a second torque transmission frame (50) of FIG. 3), a thigh fastening part for fixing the torque transmission frame to the user's leg (e.g., a first thigh fastening part (2), a second thigh fastening part (1) of FIG. 3), and a base body (e.g., a base body (80) of FIG. 3) in which a control circuit (510) for controlling the motor (534, 534-1) is disposed. A wearable device (100) may include a lighting circuit (570) including a circuit element (574) having an element value corresponding to the color of a base body and a light source element (572) that outputs light to the outside of the base body, and a control circuit (510) connected to the lighting circuit (570). One or more processors (512) may individually or collectively determine a color value of light applied to the light source element (572) according to a system status or operating mode of the wearable device (100). The circuit element (574) having an element value corresponding to the color of the base body may include at least one of a resistor element, a capacitance element, an inductance element, a transistor element, and an integrated circuit element. When the base body has a first color, the circuit element (574) may have a first element value, and when the base body has a second color different from the first color, the circuit element (574) may have a second element value different from the first element value.

[0100] In one embodiment, the control circuit (510) may further include a memory (514) that stores color control data corresponding to different colors. The color control data corresponding to different colors may include first color control data defining a color value to be applied to the light source element (572) according to a system state or operation mode of the wearable device (100) when the base body is a first color, and second color control data defining a color value to be applied to the light source element (572) according to a system state or operation mode of the wearable device (100) when the base body is a second color different from the first color.

[0101] In one embodiment, the control circuit (510) includes one or more processors (512) that control the light source elements (572), and the one or more processors (512) can individually or collectively measure an electrical signal value that depends on an element value of the circuit element (574) and control a color value of light applied to the light source elements (572) based on the measured electrical signal value. The electrical signal value can include at least one of a current signal and a voltage signal depending on the element value of the circuit element (574).

[0102] In one embodiment, one or more processors (512) may individually or collectively select target color control data to be applied to the light source element (572) based on measured electrical signal values ​​from among color control data corresponding to different colors of the base body of the wearable device (100), and control the color value of light applied to the light source element (572) according to the selected target color control data.

[0103] In one embodiment, one or more processors (512) can individually or collectively recognize element values ​​of circuit elements (574) based on measured electrical signal values, and select target color control data corresponding to the recognized element values ​​from among color control data corresponding to different colors of the base body.

[0104] In one embodiment, one or more processors (512) may individually or collectively select target color control data based on predefined color-specific reference values ​​of the base body and measured electrical signal values.

[0122] In one embodiment, the electronic device (210) can receive color information about the base body of the wearable device (100) from the wearable device (100). As described above, the wearable device (100) can recognize the color of the base body based on the element values ​​of the circuit elements (e.g., the circuit elements (574) of FIG. 5) present in the lighting circuit (e.g., the lighting circuit (570) of FIG. 5) and can transmit a color value representing the color of the recognized base body to the electronic device (210).

The communication circuit (730) may receive information related to the wearable device (100) from the wearable device (100) (e.g., operation mode information, charging status information, setting information, product information). When the product information of the wearable device (100) is received from the wearable device (100), the processor (710) may extract a color value representing the color of the base body of the wearable device (100) from model code data in which model information of the wearable device (100) is recorded from the received product information, and recognize the color of the base body of the wearable device (100) based on the extracted color value.

[0125]

[0126] FIG. 8 is a drawing for explaining the color difference of light output by a lighting module according to the color of the base body according to various embodiments.

[0127] Referring to FIG. 8, there are illustrated cases (810) where the base body (80) of the wearable device (100) has a first color (e.g., white) and cases (820) where the base body (80) of the wearable device (100) has a second color (e.g., black). In cases (810) and (820), light of a specific color may be output from the light source element (e.g., the light source element (572) of FIG. 5) of the lighting module (85) according to the system status or operation mode of the wearable device (100). If the colors of the base bodies (80) are different in cases (810) and (820) but the lighting module (85) outputs color light of the same color value, a difference in color perception may occur between cases (810) and (820) due to a difference in background color. Even though the lighting module (85) outputs color light of the same color value, the color sensation perceived by the user in case (810) may be different from the color sensation perceived by the user in case (820). To reduce the possibility of such a difference in color perception, it is necessary to adjust the color properties of the color light output by the light source element of the lighting module (85) according to the color of the base body (80).

[0128] As described above, the processor of the wearable device (100) (e.g., the processor (512) of FIG. 5) can recognize the element value of the circuit element (e.g., the circuit element (574) of FIG. 5) of the lighting circuit (e.g., the lighting circuit (570) of FIG. 5) included in the lighting module (85) and recognize the color of the base body (80) based on the recognized element value. For each wearable device, a circuit element having an element value corresponding to the color of the base body (80) of the corresponding wearable device may be mounted in the lighting circuit. The memory of the wearable device (100) (e.g., the memory (514) of FIG. 5) may store the element value of the circuit element of the lighting circuit or the color control data defined for each color of the base body (80). The processor may select, from among several pieces of color control data, target color control data corresponding to the element value of the recognized circuit element or the color of the recognized base body (80). The processor can control the color value of color light output by the light source element according to the selected target color control data.

[0129] In both cases (810) and (820), it is assumed that blue-colored light is output from the light source element of the lighting module (85) to indicate that the wearable device (100) is operating in the exercise assistance mode. In case (810), if it is recognized that the color of the base body (80) is the first color, first target color control data corresponding to the first color can be used to control the colored light output by the light source element, and color light with a color value of (R(red), G(green), B(blue)) = (19, 255, 183) can be output from the light source element according to the color value control according to the first target color control data. In case (820), if it is recognized that the color of the base body (80) is a second color, second target color control data corresponding to the second color can be used to control the color light output by the light source element, and color light with a color value of (R, G, B) = (7, 227, 181) can be output from the light source element according to the color value control according to the second target color control data. By using the color control data according to the color of the base body (80), the difference in color perception caused by the color difference of the base body (80) can be reduced, and the original intended color sensation of the color light can be conveyed.

[0130]

[0131] FIG. 9 is a drawing for explaining recognizing the color of a base body according to various embodiments and controlling the color light output of a light source element according to the recognized color of the base body.

[0132] In the manufacturing process of a wearable device (100), a base body lighting module (910) equipped with a lighting module (e.g., a lighting module (85) of FIG. 3) on the base body may be coupled with a control circuit (510). The lighting module may include a lighting circuit (570), and the lighting circuit (570) may include a light source element (572) and a circuit element (920).

[0133] The processor (512) and / or memory (514) of the control circuit (510) may be mounted without knowing the color of the base body (e.g., the base body (80) of FIG. 3) of the wearable device (100) before being mounted on the wearable device (100). In order for the processor (512) to be able to distinguish the color of the base body and control the color light of the light source element (572) according to the color of the base body, a circuit element (920) having an element value corresponding to the color of the base body may be mounted on the lighting circuit (570). The circuit element (920) may be, for example, a resistance element having a resistance value corresponding to the color value of the base body, and may be a surface mount device (SMD) resistor mounted on a PCB (printed circuit board) of the lighting circuit (570). However, the circuit element (920) is not limited to being a resistance element, and the circuit element (920) may be a resistance element, a capacitance element, an inductance element, a transistor element, an integrated circuit element, or any combination thereof.

[0134] The memory (514) may store data indicating a correspondence between each element value of the recognized circuit element (920) and the color of the base body (corresponding to the exterior color of the wearable device (100)) and color control data for each color of the multiple base bodies. The memory (514) may also store color control data corresponding to each element value of the recognized circuit element (920). The color control data corresponding to each color may include a color setting value of the light source element (572) for each system status and / or operation mode of the wearable device (100) according to each color of the base body.

[0135] In one embodiment, the processor (512) may have a general purpose input output (GPIO) port capable of recognizing the element values ​​of the circuit element (920). The processor (512) may be connected to a light source element (572) of the lighting circuit (570) through a first port (932) and may be connected to a circuit element (920) of the lighting circuit (570) through a second port (934).

[0136] In one embodiment, when the wearable device (100) is first powered on, the processor (512) can recognize the element value of the circuit element (920) based on the electrical signal value (e.g., current signal value or voltage signal value) measured through the second port (934), and identify the color of the base body based on the recognized element value. The processor (512) can select target color control data, which is color control data corresponding to the element value of the recognized circuit element (920), from among the color control data corresponding to each color of the base body stored in the memory (514). The processor (512) can control the color value of the colored light output by the light source element (572) according to the selected target color control data. In this way, the processor (512) can automatically set the color control data mapped to the element value of the circuit element (920) mounted on the lighting circuit (570).
