Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of International Application No. PCT/KR2022/004818 designating the United States, filed on Apr. 5, 2022, in the Korean Intellectual Property Office and claiming priority to Korean Patent Application No. 10-2021-0045491, filed on Apr. 7, 2021, in the Korean Intellectual Property Office, the disclosures of which are incorporated by reference herein in their entireties. 
    
    
     BACKGROUND 
     Field 
     The disclosure relates to a method for controlling a specified function, and an electronic device supporting the same. 
     Description of Related Art 
     An electronic device for providing an augmented reality technology may superimpose a virtual object onto an actually existing thing or environment and simultaneously provide the virtual object and the thing through a display. 
     Electronic devices may be formed in various types to provide augmented reality to users. For example, electronic devices for providing augmented reality may include a head-mounted device (HMD) type or non-head mounted device (non-HMD) type. 
     HMD-type electronic devices for providing augmented reality may include a glasses type. In the case of the glasses type, a temple may be designed in a fixed manner on a main unit including a display so as to contact the user&#39;s body. No separate case capable of storing the glasses exists because the temple is fixed. This is because if the glasses having a fixed temple is stored in a glasses case, the glasses may be fractured. 
     In order to address the problem of glass fracture, the glasses structure may be changed such that the temple can be folded, thereby making it possible to store the glasses in the glasses case. The glasses case can be used to simply store the glasses. In addition, mechanical characteristics of the glasses make it difficult to mount a large-capacity battery that occupies a predetermined area, and the glasses using time may be short. 
     SUMMARY 
     Embodiments of the disclosure provide a case capable of storing glasses connected to another electronic device (for example, smartphone) may include a function of an electronic device related to the glass (for example, charging function and glass information display) in addition to the usage of simple glasses storage. 
     Accordingly, a specified function of the glasses may be controlled, based on the state in which the glasses are mounted inside the case, the temple folding state, and the user&#39;s wearing state. In addition, the amount of power of the glasses battery may be identified, and the timepoint to execute the specified function may be controlled based on the identified amount of power. 
     According to an example embodiment disclosed herein, a first electronic device may include: a body including at least one sensor, a temple connected to the body, a hinge connecting the body and the temple and configured to allow the temple connected to the body to be folded in a specified direction within a specified angle, and a processor functionally connected to the at least one sensor, wherein the processor is configured to: determine whether the first electronic device is in a first state of being mounted in a second electronic device, identify whether the first electronic device is in a second state of being worn, through the at least one sensor, and execute a specified function of the first electronic device, based on at least one of the first state and/or the second state. 
     A method of operating a first electronic device including a body, a hinge, and a temple according to an example embodiment disclosed herein may include” determining whether the first electronic device is in a first state of being mounted in a second electronic device, determining whether the first electronic device is in a second state of being worn, through at least one sensor, and executing a specified function of the first electronic device, based on the first state and the second state. 
     According to various example embodiments disclosed herein, a method for controlling a specified function and an electronic device supporting the same may control the specified function of the electronic device, based on the state in which the electronic device is mounted in another electronic device (case), the temple folding state, and the user&#39;s wearing state, such that no separate input is required from the user, thereby providing convenience. 
     In addition, the amount of power in the battery of the electronic device may be identified, and a low-power mode may be entered based on the amount of power. In the low-power mode, a timepoint to execute a function of the electronic device may be controlled to be a timepoint at which power can be saved (for example, if the user mounts the electronic device, a specified function to be executed previously is executed simultaneously) such that, by improving the electronic device use time, the user can use the electronic device for a long time. 
     Various other advantageous effects identified explicitly or implicitly through the disclosure may be provided.

The communication module  190  may include one or more communication processors that are operable independently from the processor  120  (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module  190  may include a wireless communication module  192  (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module  194  (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network  198  (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network  199  (e.g., 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., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module  192  may identify and authenticate the electronic device  101  in a communication network, such as the first network  198  or the second network  199 , using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module  196 .

     At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)). 
     According to an embodiment, commands or data may be transmitted or received between the electronic device  101  and the external electronic device  104  via the server  108  coupled with the second network  199 . Each of the electronic devices  102  or  104  may be a device of a same type as, or a different type, from the electronic device  101 . According to an embodiment, all or some of operations to be executed at the electronic device  101  may be executed at one or more of the external electronic devices  102 ,  104 , or  108 .

     When the first electronic device  200  is switched to the wake-up mode, the first electronic device  200  may identify a second state of the first electronic device  200 . The second state may include a state in which the first electronic device  200  is worn on a user&#39;s body. According to an embodiment, the first electronic device  200  may determine the second state of the first electronic device  200  through at least one sensor to be described later. 
     When the first electronic device  200  corresponds to the second state, the first electronic device  200  may receive data from a third electronic device (e.g., a third electronic device  302  of  FIG.  3 B ) to output the data. 
     According to an embodiment, the first electronic device  200  may include a body  210 , a hinge  230 , and a temple  250 . The first electronic device  200  may be in the form of glasses. 
     According to an embodiment, the body  210  may include a camera  211  (e.g., the camera module  180  of  FIG.  1   ), a display  213  (e.g., the display module  160  of  FIG.  1   ), a sensor  215  (e.g., the sensor module  176  of  FIG.  1   ), a processor (e.g., including processing circuitry)  217  (e.g., the processor  120  of  FIG.  1   ), and a communication module (e.g., including communication circuitry)  219 . However, the configuration of the body  210  is not limited thereto. 
     According to various embodiments, the body  210  may not include at least one of the above-described components, and may include at least one other component. For example, the body  210  may include the communication module  219  (e.g., the communication module  190  of  FIG.  1   ). The processor  217  may control the communication module to transmit or receive data to or from another electronic device (e.g., the electronic device  102  or  104  of  FIG.  1   ) or a server (e.g., the server  108  of  FIG.  1   ) through the communication module. 
     According to an embodiment, the hinge  230  may connect the body  210  and the temple  250 . The hinge  230  may allow the temple  250  connected to the body  210  to be folded (e.g., a folded state) or unfolded (e.g., an unfolded state) in a specified direction within a predetermined angle. The temple  250  may include a temple structure connected to the body including an optical member (e.g., a display) among glass structures. 
     According to an embodiment, the processor  217  may identify a folded state or an unfolded state of the temple  250  through a folding detection sensor (not shown). A method for identifying the folding state will be described in detail below. 
     According to an embodiment, the processor  217  may identify the first state related to a state in which the first electronic device  200  is mounted in the second electronic device  301 . The second electronic device  301  may be a case-type electronic device for storing and charging the first electronic device  200 . 
     According to an embodiment, the processor  217  may determine whether the first electronic device  200  corresponds to the first state. The first state may include a state in which the first electronic device  200  is mounted in the second electronic device  301 . In an embodiment, in a case of being connected to the second electronic device  301  through, for example, a pogo pin disposed on the first electronic device  200 , the first electronic device  200  may determine that the first electronic device  200  is mounted in the second electronic device  301 . 
     According to an embodiment, the processor  217  may identify that the first electronic device  200  is mounted in the second electronic device  301 , based on the identified first state. When the first electronic device  200  is mounted in the second electronic device  301 , the processor  217  may maintain the first mode (e.g., a sleep mode) of the first electronic device  200 . In addition, the processor  217  may transmit at least one of temperature information and battery information of the first electronic device  200  to the second electronic device  301  through the communication module  219 . That is, when the first electronic device  200  is mounted in the second electronic device  301 , the first electronic device  200  may be in a state in which communication is connected with the second electronic device  301  via a wired/wireless network. 
     A detailed description for identifying the first state will be described below with reference to  FIG.  5   . 
     According to an embodiment, the processor  217  may identify that the first electronic device  200  is not mounted in the second electronic device  301 , based on the identified first state. When the first electronic device  200  is not mounted in the second electronic device  301 , the processor  217  may execute a first function. The first function may include a function in which the processor  217  switches from the first mode (e.g., a sleep mode) to the second mode (e.g., a wake-up mode). 
     For example, the first mode may be a power saving mode of causing the processor  217  to wait so as to reduce current consumption when the first electronic device  200  is not used by a user for a predetermined (e.g., specified) time. The second mode may be a mode of activating the processor  217  when an operation to use the first electronic device  200  by the user is detected. 
     According to an embodiment, in a case of executing the first function, the processor  217  may release a communication connection with the second electronic device  301  via a wired/wireless network. In addition, the processor  217  may release communication with the second electronic device  301  and establish communication with a third electronic device  302  via a wired/wireless network. That is, when the first electronic device  200  is not mounted in the second electronic device  301 , the processor  217  may execute the first function of switching to the second mode (e.g., a wake-up mode) and releasing a communication connection with the second electronic device  301  to establish communication with the third electronic device  302 . 
     According to an embodiment, after executing the first function, the processor  217  may identify a folding state of the temple  250  included in the first electronic device  200 . The folding state may include a state in which the temple  250  is folded (a folded state) or unfolded (an unfolded state) in a specified direction. 
     According to an embodiment, the processor  217  may identify the folding state, based on data obtained through the folding detection sensor. 
     For example, when a value of data obtained from the folding detection sensor is included within a range pre-configured in the folding detection sensor, the processor  217  may identify that the temple  250  is in an unfolded state. For another example, when a value of data obtained from the folding detection sensor is not included within the range pre-configured in the folding detection sensor, the processor  217  may identify that the temple  250  is in a folded state. 
     In relation to the folding detection sensor, for example, the folding detection sensor may include, for example, and without limitation, a proximity sensor, a pressure sensor, and a grip sensor which can detect a folding state of the temple  250 , and is not limited thereto as long as the same is a sensor capable of detecting a folding state of the temple  250 . The folding detection sensor may be at least one sensor different from the sensor  215  (e.g., at least one sensor). 
     For example, the processor  217  may identify the folding state through the proximity sensor. When data obtained from the proximity sensor is out of a range pre-configured in the proximity sensor, the processor  217  may identify that the temple  250  is in contact with the body  210  (an unfolded state). 
     According to an embodiment, the processor  217  may identify a folding state of the temple  250  through a circuit (not shown) as well as the folding detection sensor. For example, the circuit may include an interrupt circuit and a power IC. In addition, the circuit may be disposed near a position where the body  210  and the temple  250  are connected to each other. 
     For another example, the processor  217  may identify the folding state through the interrupt circuit. When a level of a received voltage signal is changed from a “high” level to a “low” level, the processor  217  may identify that the temple  250  is in contact with the body  210  (unfolded) (e.g., a state in which a glasses frame is unfolded). 
     According to an embodiment, the processor  217  may identify that the temple  250  is folded (a folded state). When the temple  250  is in a folded state, the processor  217  may maintain the first function. 
     According to an embodiment, the processor  217  may identify that the temple  250  is unfolded (an unfolded state), based on the folding state. 
     When the temple  250  is unfolded, the processor  217  may execute a second function. The second function may be a function in which the processor  217  switches the display  213  to an on state and activates the sensor  215  (e.g., at least one sensor). The sensor  215  may be, as a sensor for identifying whether the first electronic device  200  is worn on a user&#39;s body, a sensor different from the folding detection sensor. The sensor  215  may include a proximity sensor, an ultrasonic sensor, a grip sensor, and a biometric sensor, and is not limited thereto as long as the same is a sensor capable of determining whether the device is worn on a user&#39;s body. A description related to the second function will be described in detail with reference to  FIG.  6   . 
     According to an embodiment, when the activation of the sensor  215  is completed, the processor  217  may identify whether the first electronic device  200  is in the second state related to a state of being worn on a user&#39;s body, through the sensor  215 . 
     According to an embodiment, in a case of detecting that the first electronic device  200  is worn on a user&#39;s body, the processor  217  may execute a third function. For example, the third function may be a function of operating the camera  211  and outputting, on the display  213 , a virtual object related to a thing or a place recognized by the first electronic device  200  through the camera  211 . A description related to the third function will be described in detail with reference to  FIG.  7   . 
     According to an embodiment, the processor  217  may identify the amount of power of a battery  251  (e.g., the battery  189  of  FIG.  1   ) included in the first electronic device  200 . For example, the battery  251  may be included in the temple  250 . When the amount of power of the battery  251  is less than or equal to a specified value, the processor  217  may switch the first electronic device  200  to a low power mode. The low power mode may be a mode for minimizing and/or reducing power consumption of the first electronic device  200 . 
     According to an embodiment, the processor  217  may switch the first electronic device  200  to the low power mode, and change an execution time point of at least one function among the multiple functions (the first function, the second function, and the third function) to a time point at which power consumption can be minimized and/or reduced. For example, the processor  217  may identify the second state. The processor  217  may execute the first function (e.g., switching to a second mode (e.g., a wake-up mode)) executed when the first electronic device  200  is not mounted in the second electronic device  301 , when the first electronic device  200  is worn on a user&#39;s body. 
     In an embodiment, an activation time point of the first function, the second function, and the third function may be changed according to a user&#39;s configuration. For example, an on function of the display  213  may be performed, according to the user&#39;s configuration, in at least one state among the second state in which the first electronic device  200  is worn on a user&#39;s body, an unfolded state of the temple  250  of the first electronic device  200 , and a state in which the first electronic device  200  is not received in the second electronic device  301 . The user configuration may include a configuration previously specified by a user in the processor  217  of the first electronic device  200 . For another example, the processor  217  may identify the folding state. The processor  217  may execute the first function when the temple  250  is in an unfolded state. That is, in the low power mode, the processor  217  may change an execution time point of the functions to a later time point, and thus reduce current consumption of the first electronic device  200 .

     According to an embodiment, the communication module  312  (e.g., the communication module  190  of  FIG.  1   ) may include various communication circuitry and support communication between the first electronic devices  200 . For example, the communication module  312  may establish wireless communication with the first electronic device  200  according to a prescribed communication protocol, and transmit or receive a signal or data using a frequency band supporting the wireless communication. 
     The wireless communication may include, for example, at least one of ultra-wideband (UWB), communication, Wi-Fi communication, Bluetooth (BT) communication, and low energy Bluetooth (BLE) communication.

The battery  313  may be one of a lithium ion battery (Li-ion), a lithium ion polymer battery (Li-ion polymer), a lead storage battery, a nickel-cadmium battery (NiCd), and a nickel hydrogen storage battery (NiMH). When the magnitude of the current supplied to the battery  313  is greater than the magnitude of the current output from the battery  313 , the battery  313  may be charged. When the magnitude of the current output from the battery  313  is greater than the magnitude of the current supplied to the battery  313 , the battery  313  may be discharged. 
     According to an embodiment, the charger circuitry  314  may correspond to a charger IC and/or a charging module for controlling charging. The charger circuitry  314  may be disposed between the battery  313  and at least one hardware component electrically connected thereto so as to control the flow of power output from the battery  313  and/or power supplied toward the battery  313 . 
     According to an embodiment, the second electronic device  301  may receive power from an external power source using the first interface  315  (e.g., a wired interface and/or a wireless interface). The charger circuitry  314  may receive power from an external power source using the first interface  315 . The charger circuitry  314  may charge the battery  313  and/or the first electronic device  200  connected through a second interface  316  using power supplied from an external power source. 
     According to an embodiment, the second interface  316  may be an interface which is connected to the first electronic device  200  to supply power to the first electronic device  200 , and transmit or receive data to or from the first electronic device  200 . In an embodiment, a control command may be received from the first electronic device  200  through the second interface  316 . In an embodiment, the second interface  316  may be a connection terminal for connecting to the first electronic device  200 . 
       FIGS.  3 A and  3 B  are diagrams illustrating an example method for providing a function according to a connection state between electronic devices, according to various embodiments. 
     Referring to  FIG.  3 A , the first electronic device  200  (e.g., the electronic device  101  of  FIG.  1   ) may be in a state of being mounted in the second electronic device  301 . When the first electronic device  200  is mounted in the second electronic device  301 , a temple (e.g., the temple  250  of  FIG.  2 A ) may be in a folded state. In an embodiment, when the first electronic device  200  corresponds to a first state of being mounted in the second electronic device  301 , the first electronic device  200  may be physically and/or electrically connected to the second electronic device  301 . 
     According to an embodiment, the first electronic device  200  may identify the first state related to whether the first electronic device is mounted in the second electronic device  301 . When it is identified that the first electronic device is mounted in the second electronic device  301 , based on the identified first state, the first electronic device  200  may transmit at least one of temperature information and battery information to the second electronic device  301  through the communication module  219 . 
     For example, when the first electronic device  200  is mounted in the second electronic device  301 , the first electronic device  200  may be in a state of being communicatively connected to the second electronic device  301 . 
     A detailed description for identifying the first state will be described below with reference to  FIG.  5   . 
     Referring to  FIG.  3 B , the first electronic device  200  (e.g., the electronic device  101  of  FIG.  1   ) may be in a state of not being mounted in the second electronic device  301 . The first  5  electronic device  200  may determine whether the first electronic device  200  is in the first state of being mounted in the second electronic device  301 . When the first electronic device  200  is not mounted in the second electronic device  301 , based on the identified first state, the first electronic device  200  may execute a first function. When the processor  217  executes the first function, the first electronic device  200  may be switched from a first mode (e.g., a sleep mode) to a second mode (e.g., a wake-up mode).

When it is detected that the first electronic device  200  is worn on a user&#39;s body through the sensor  215 , the first electronic device  200  may receive image data to be output on the display  213  from the third electronic device  302 . 
       FIG.  4    is a flowchart illustrating an example method for controlling a specified function of the first electronic device  200 , according to various embodiments. 
     In operation  401  of  FIG.  4   , a processor (e.g., the processor  120  of  FIG.  1    or the processor  217  of  FIG.  2 A ) of a first electronic device (e.g., the electronic device  101  of  FIG.  1    or the first electronic device  200  of  FIG.  2 A ) may determine whether the first electronic device  200  is in a first state of being mounted in the second electronic device  301 . The first electronic device  200  may be connected within the second electronic device  301  to the second interface  316  disposed on the second electronic device  301  in a wired manner, and recognize that the first electronic device is mounted in the second electronic device  301 . 
     According to an embodiment, the processor  217  may identify that the first electronic device  200  is mounted in the second electronic device  301 , based on the first state. 
     When the first electronic device  200  is mounted in the second electronic device  301 , the processor  217  may transmit at least one of temperature information and battery information of the first electronic device  200  to the second electronic device  301 . The temperature information may be information related to the current temperature of the first electronic device  200 , and the battery information may be information related to the amount of power stored in the battery  251  of the first electronic device  200 . When the first electronic device  200  is mounted in the second electronic device  301 , the processor  217  may maintain a first mode. In an example, the first mode may be a power saving mode of causing the processor  217  to wait so as to reduce current consumption of the first electronic device  200 . 
     According to an embodiment, the processor  217  may identify that the first electronic device  200  is not mounted in the second electronic device  301 , based on the first state. When the first electronic device  200  is not mounted in the second electronic device  301 , the processor  217  may execute a first function. A detailed description related to the first function will be disclosed in  FIG.  5   . 
     According to an embodiment, the processor  217  may execute the first function and start operation  403 . 
     In operation  403 , the processor  217  may determine whether the first electronic device  200  is in a second state of being worn on a user&#39;s body. 
     According to an embodiment, the processor  217  may identify whether the first electronic device  200  is worn on the user&#39;s body through a sensor (e.g., the sensor module  176  of  FIG.  1    or the sensor  215  of  FIG.  2 A ). For example, when the sensor  215  is a biometric sensor, the processor  217  may identify whether the first electronic device  200  is currently mounted or not mounted on the user&#39;s body, based on data obtained through the biometric sensor. 
     In operation  405 , the processor  217  may execute a specified function, based on the first state and the second state.

That is, the processor  217  may provide a specific object and virtual information to a user. When the first electronic device  200  is not mounted in the second electronic device  301  and the first electronic device  200  is worn on the user&#39;s body, the processor  217  may execute the specified function. 
       FIG.  5    is a flowchart illustrating an example method for providing a first function, according to various embodiments. 
     According to an embodiment, a first function may be a function executed by the processor  217  of the first electronic device  200  when the first electronic device  200  is physically and/or electrically disconnected from the second interface  316  of the second electronic device  301 . In an example, the first function may include a function in which the processor  217  switches from a first mode (e.g., a sleep mode) to a second mode (e.g., a wake-up mode). In an example, the first function may be a function executed by the processor  217  in response to the processor  217  determining that the first electronic device  200  is not mounted in the second electronic device  301  and thus does not correspond to a first state. 
     In operation  501  of  FIG.  5   , a processor (e.g., the processor  120  of  FIG.  1    or the processor  217  of  FIG.  2 A ) of a first electronic device (e.g., the electronic device  101  of  FIG.  1    or the first electronic device  200  of  FIG.  2 A ) may determine whether the first electronic device  200  is in the first state of being mounted in the second electronic device  301 . 
     In an embodiment, in a case of determining that the first electronic device  200  is mounted in the second electronic device  301 , the processor  217  may determine that the first electronic device  200  corresponds to the first state. 
     In an embodiment, when the first electronic device  200  is connected to the second electronic device  301  through the second interface  316  of the second electronic device  301 , the processor  217  may determine that the first electronic device  200  is mounted in the second electronic device  301 . In an example, when a wired connection of the first electronic device  200  with the second interface  316  of the second electronic device  301  is released, the processor  217  may determine that the first electronic device  200  is not mounted in the second electronic device  301 . 
     According to an embodiment, when it is identified that the first electronic device  200  is mounted in the second electronic device  301 , the processor  217  may perform operation  503 . 
     In an embodiment, in operation  503 , the processor  217  may maintain a state of the first electronic device  200  in the first mode (e.g., a sleep mode). In an example, the processor  217  may maintain a first mode (e.g., a sleep mode) state when the first electronic device  200  is connected to the second electronic device  301  through the second interface  316  of the second electronic device  301 . The first mode may be a mode for causing the processor  217  of the first electronic device  200  to wait. In an example, the first mode may be a state in which data is not transmitted from the third electronic device  302 . 
     In an example, the processor  217  may transmit at least one of the temperature information and the battery information to the second electronic device  301  while maintaining the first mode. The temperature information may be information related to the current temperature of the first electronic device  200 , and the battery information may be information related to the amount of power stored in the battery  251  of the first electronic device  200 . 
     According to an embodiment, when the first electronic device  200  is mounted in the second electronic device  301 , the processor  217  may receive power from the second electronic device  301  to charge a battery (e.g., the battery  189  of  FIG.  1    or the battery  251  of  FIG.  2 A ) of the first electronic device  200 . For example, when the first electronic device  200  is mounted in the second electronic device  301 , while the first mode (e.g., a sleep mode) is maintained, the battery  251  may be charged and a communication connection with another electronic device may be maintained. 
     According to an embodiment, the processor  217  may identify that the first electronic device  200  is in a state of not being mounted in the second electronic device  301 , based on the first state. In an example, when the first electronic device  200  is physically and/or electrically disconnected from the second interface  316  of the second electronic device  301 , the processor  217  may determine that the first electronic device  200  is not mounted in the second electronic device  301 . When it is identified that the first electronic device  200  is not mounted in the second electronic device  301 , the processor  217  may perform operation  505 . 
     In operation  505 , the processor  217  may perform the first function of switching a state of the first electronic device  200  from the first mode (e.g., a sleep mode) to the second mode (e.g., a wake-up mode). 
     According to an embodiment, when the first electronic device  200  is not mounted in the second electronic device  301 , the processor  217  may execute the first function. The first function may include a function of switching from the first mode (e.g., a sleep mode) to the second mode (e.g., a wake-up mode). For example, the first mode may be a power saving mode of causing the processor  217  to wait so as to reduce current consumption when the first electronic device  200  is not used by a user for a predetermined time. The second mode may be a mode of activating the processor  217  when an operation to use the first electronic device  200  by the user is detected. That is, since the processor  217  has a high probability of using the first electronic device  200  by the user when the first electronic device  200  is not mounted in the second electronic device  301 , the first electronic device  200  may be switched from the first mode to the second mode. 
     According to an embodiment, the first electronic device  200  may be mounted in the second electronic device  301  in a state in which power is turned off. When the first electronic device  200  has been mounted in the second electronic device  301  in the state in which power is off, and then a wired connection or a wireless connection is released, the power may be automatically switched to an on state. When the power of the first electronic device  200  is switched to the on state, the processor  217  may switch the first electronic device  200  to the second mode. 
     According to an embodiment, when the first electronic device  200  is switched to the second mode, the processor  217  may perform operation  507 . 
     In operation  507 , the processor  217  may release a communication connection with the second electronic device  301 . 
     According to an embodiment, when the first electronic device  200  is not mounted in the second electronic device  301 , the processor  217  may release the existing communication which has been connected with the second electronic device  301  in order to establish a communication connection with the third electronic device  302 . That is, the processor  217  may release the communication connection with the second electronic device  301  to establish communication with the third electronic device  302  (e.g., a smart phone) of the user who is expected to use the first electronic device  200 . 
     In operation  509 , the processor  217  may establish communication with the third electronic device  302 . 
     According to an embodiment, when the communication connection with the second electronic device  301  is released, the processor  217  may establish communication with the third electronic device  302 . The processor  217  may be connected with the third electronic device  302  through the communication module  219  in order to receive data for providing augmented reality to the user from the third electronic device  302 . 
     According to an embodiment, when communication with the third electronic device  302  is established, the processor  217  may output, on the display  213  of the first electronic device  200 , information (e.g., battery level information) on the first electronic device  200  and/or information (e.g., information on a device name of the third electronic device  302  or a battery level of the third electronic device  302 ) on the third electronic device  302 . 
     In an embodiment, operation  507  may be omitted. For example, the processor  217  may not release communication with the second electronic device  301  and establish communication with the third electronic device  302 . That is, the first electronic device  200  may establish communication with the second electronic device  301  and the third electronic device  302  in parallel. 
       FIG.  6    is a flowchart illustrating an example method for providing a second function, according to various embodiments. 
     According to an embodiment, a second function may be a function of the first electronic device  200  being executed by the processor  217  of the first electronic device  200  when the temple  250  of the first electronic device  200  is in an unfolded state. In an example, the second function may be a function performed by the processor  217  by identifying a folding state of the temple  250  included in the first electronic device  200  by the processor  217 . 
     In operation  601  of  FIG.  6   , a processor (e.g., the processor  120  of  FIG.  1    or the processor  217  of  FIG.  2 A ) of a first electronic device (e.g., the electronic device  101  of  FIG.  1    or the first electronic device  200  of  FIG.  2 A ) may identify a folding state of a temple (e.g., the temple  250  of  FIG.  2 A ). The folding state may include a state in which the temple  250  is folded (a folded state) in a specified direction or unfolded (an unfolded state) in a specified direction. 
     According to an embodiment, the processor  217  may identify the folding state of the temple  250  through at least one of a folding detection sensor (not shown) and a circuit (not shown) included in a body (e.g., the body  210  of  FIG.  2 A ). In addition, the processor  217  may identify the folding state of the temple  250 , based on whether a folding angle of the temple  250  is included in a recognition area or a non-recognition area. 
     For example, the folding detection sensor may include at least one of a proximity sensor, a grip sensor, an ultrasonic sensor, and a pressure sensor, and is not limited thereto as long as the same is a sensor capable of identifying a folding state of the temple  250 . In addition, the sensor may include an interrupt circuit and a power IC circuit, but is not limited thereto when the sensor includes a circuit which can identify a folding state of the temple  250 . 
     For example, the body  210  may include a power IC for outputting power at a predetermined time interval, and the temple  250  may include a ground GND. When the temple  250  is unfolded in a specified direction and is in contact with the body  210  (a state in which a glasses frame is unfolded), the processor  217  may identify that power of the power IC is short-circuited to the ground included in the temple  250  and the temple  250  is in an unfolded state through a short-circuiting detection function. When the processor  217  recognizes the release of the short-circuiting through the short-circuiting detection function, the processor  217  may identify that the temple  250  is in a folded state. 
     For another example, the body  210  may include a power IC including power at a predetermined time interval, and a circuit for connecting the output of the power to the temple  250 . When the temple  250  is unfolded in a specified direction, the processor  217  may recognize power through the power IC as the power normally forms a loop. The processor  217  may recognize the power and identify that the temple  250  is in an unfolded state. In addition, when the power does not form a loop, the processor  217  may not recognize the power through the power IC and may identify that the temple  250  is in a folded state. 
     For still another example, the folding detection sensor may be a grip sensor. The processor  217  may identify the folding state through the grip sensor. In order for the grip sensor to detect the folding state, a dielectric counterpart having a capacitance component may be included in the temple  250 . When the temple  250  is in contact with the body  210 , the processor  217  may recognize the capacitance component through the grip sensor so as to identify that the temple  250  is in a folded state. In addition, when the temple  250  is not in contact with the body  210 , the processor  217  may not recognize the capacitance component, and thus may identify that the temple  250  is in an unfolded state. 
     The folding detection sensor may be an ultrasonic sensor. The processor  217  may identify a distance between the body  210  and the temple  250 , based on a signal received through the ultrasonic sensor. For example, when the body  210  and the temple  250  come close to each other by a preconfigured distance or less, the temple  250  may be identified to be in an unfolded state. When the distance between the body  210  and the temple  250  is greater than or equal to a preconfigured distance, the temple  250  may be identified to be in a folded state. In addition, the folding detection sensor may be a pressure sensor. The processor  217  may identify whether the temple  250  is in contact with the body  210 , based on a signal received through the pressure sensor. For example, in a case of receiving a signal included within a recognition range of the pressure sensor, the processor  217  may identify that the temple  250  is in an unfolded state in which the temple is in contact with the body  210 . In a case of not receiving a separate signal through the pressure sensor, the processor  217  may identify that the temple  250  is in a folded state in which the temple is not in contact with the body  210 . 
     According to an embodiment, in a case of detecting that the temple  250  is in a folded state, the processor  217  may perform operation  603 . 
     In operation  603 , the processor  217  may maintain a first function when it is identified that the temple  250  is in a folded state. The first function may include a function performed by the processor  217  when the first electronic device  200  does not correspond to a first state. In an example, the first state may be a state in which the first electronic device  200  is connected with the second interface  316  of the second electronic device  301  and is received in the second electronic device  301 . 
     According to an embodiment, when it is identified that the temple is in an unfolded state, the processor  217  may perform operation  605 . 
     In operation  605 , when it is identified that the temple  250  is in an unfolded state, the processor  217  may switch a display (e.g., the display module  160  of  FIG.  1    or the display  213  of  FIG.  2 A ) to an on state. In an example, when it is identified that the temple  250  is in an unfolded state, the processor  217  may switch the display  213  to the on state while maintaining the first function. 
     According to an embodiment, when the temple  250  is unfolded, the processor  217  may switch the display  213  to the on state in order to display data received from the third electronic device  302  through the display  213 . The processor  217  may perform operation  607  while switching the display  213  to the on state. 
     In operation  607 , the processor  217  may activate at least one sensor  215 . 
     According to an embodiment, the at least one sensor  215  may be a sensor for identifying whether the first electronic device  200  is worn on a user&#39;s body. The processor  217  may activate the at least one sensor  215  in order to identify whether the first electronic device  200  is worn on the user&#39;s body. That is, the at least one sensor  215  may be disposed in an area where the first electronic device  200  may be worn in contact with the user&#39;s body. In addition, the at least one sensor  215  may include a proximity sensor, a grip sensor, an ultrasonic sensor, and a pressure sensor different from the folding detection sensor. 
     According to an embodiment, the processor  217  may activate a microphone (not shown) (e.g., the input module  150  of  FIG.  1   ) and a communication module (not shown) (e.g., the communication module  190  of  FIG.  1   ) included in the first electronic device  200 . That is, when the temple  250  is in an unfolded state, the processor  217  may execute a second function of switching the display  213  to an on state and activating configurations which may identify whether the first electronic device  200  is worn on a user&#39;s body. 
       FIG.  7    is a flowchart illustrating an example method for providing a third function, according to various embodiments. 
     In an embodiment, a third function may be a function executed by the processor  217  of the first electronic device  200  when the first electronic device  200  is worn on a user&#39;s body. In an example, the third function may be a function executed by the processor  217  by identifying whether the first electronic device  200  corresponds to a second state by the processor  217 . 
     In operation  701  of  FIG.  7    according to an embodiment, a processor (e.g., the processor  120  of  FIG.  1    or the processor  217  of  FIG.  2 A ) of a first electronic device (e.g., the electronic device  101  of  FIG.  1    or the first electronic device  200  of  FIG.  2 A ) may identify the second state corresponding to a state of being worn on a user&#39;s body. 
     In an embodiment, the processor  217  may perform operation  701  through at least one sensor (e.g., the sensor module  176  of  FIG.  1    or the sensor  215  of  FIG.  2 A ) activated in operation  607 . 
     According to an embodiment, the at least one sensor  215  may be disposed in an area where the first electronic device  200  is worn in contact with the user&#39;s body. For example, in a case of receiving a value corresponding to a range value (e.g., a voltage level) configured in the at least one sensor  215 , the processor  217  may identify that the first electronic device  200  is worn on the user&#39;s body. On the other hand, for example, in a case of receiving a value larger or smaller than the range value configured in the at least one sensor, the processor  217  may identify that the first electronic device  200  is not worn on the user&#39;s body. 
     According to an embodiment, when the first electronic device  200  is not worn on the user&#39;s body, the processor  217  may execute operation  703 . 
     In operation  703  according to an embodiment, the processor  217  may maintain a second function. The second function may include a function of switching a display (e.g., the display module  160  of  FIG.  1    or the display  213  of  FIG.  2 A ) to an on state and activating the at least one sensor  215  when a temple (e.g., the temple  250  of  FIG.  2 A ) included in the first electronic device  200  is in an unfolded state. 
     In an embodiment, when the first electronic device  200  is not worn on the user&#39;s body, that is, is not in the second state, the processor  217  may output an inverted image through the display  213 . In an example, the inverted image output through the display  213  may refer to an image output in a direction opposite to a direction facing the user&#39;s body (e.g., eyes) when the first electronic device  200  is worn on the user&#39;s body. 
     According to an embodiment, when the first electronic device  200  is worn on the user&#39;s body, the processor  217  may execute operation  705 . 
     In operation  705  according to an embodiment, the processor  217  may obtain data using the camera  211 . In an example, the processor  217  may recognize or track an external object through the camera  211 . For example, the processor  217  may obtain information on eye tracking of the user wearing the first electronic device  200  using the camera  211 . 
     According to an embodiment, the processor  217  may obtain information on the surrounding environment of the user wearing the first electronic device  200  using the camera  211 . 
     In an embodiment, the processor  217  may transmit, to the third electronic device  302 , information (e.g., the information on eye tracking of the user wearing the first electronic device  200  and/or the information on the surrounding environment of the user wearing the first electronic device  200 ) obtained through the camera  211 . In an example, the third electronic device  302  may process data, based on information received from the first electronic device  200  (or the processor  217 ). In an example, the third electronic device  302  may obtain a virtual image and/or video, based on data received from the first electronic device  200 . 
     In operation  707  according to an embodiment, the processor  217  may output, through the display  213 , data obtained through the camera  211  or data received from the third electronic device  302 . 
     In an example, the processor  217  may output data obtained through the camera  211 , through the display  213 . The processor  217  may output data (e.g., data on eye tracking of the user and/or data on surrounding environment information of the user wearing the first electronic device  200 ) obtained through the camera  211 . 
     In an example, the processor  217  may transmit the obtained information to the second electronic device  301 . In an example, the second electronic device  301  may process data, based on the information received from the first electronic device  200 . The second electronic device  301  may transmit the processed data to the first electronic device  200 . The first electronic device  200  may output the data received from the second electronic device  301  through the display  213 . 
       FIG.  8    is a flowchart illustrating an example method for providing a specified function in a low power mode, according to various embodiments. 
     In operation  801  of  FIG.  8   , a processor (e.g., the processor  120  of  FIG.  1    or the processor  217  of  FIG.  2 A ) of a first electronic device (e.g., the electronic device  101  of  FIG.  1    or the first electronic device  200  of  FIG.  2 A ) may identify whether the amount of power of a battery (e.g., the battery  189  of  FIG.  1    or the battery  251  of  FIG.  2 A ) is less than or equal to a specified value. 
     According to an embodiment, when the amount of power stored in the battery  251  is greater than the specified value, the processor  217  may start operation  803 . 
     In operation  803  according to an embodiment, when the amount of power of the battery  251  is greater than or equal to the specified value, the processor  217  may maintain a normal mode. In an example, the normal mode may be a mode in which execution of a first function, a second function, and a third function is processed at a normal time point. 
     According to an embodiment, when the first electronic device  200  is not mounted in the second electronic device  301  and thus does not correspond to a first state in the normal mode, the processor  217  may execute the first function. According to an embodiment, when a temple (e.g., the temple  250  of  FIG.  2 A ) of the first electronic device  200  is in an unfolded state in the normal mode, the processor  217  may execute the second function. In addition, according to an embodiment, when the first electronic device  200  is worn on a user&#39;s body in the normal mode, the processor  217  may execute the third function. 
     For example, according to an embodiment, the processor  217  may maintain the normal mode in which one of the first function, the second function, and the third function is executed at a normal time point when the amount of power of the battery  251  is greater than or equal to the specified value. 
     According to an embodiment, when the amount of power stored in the battery  251  is less than or equal to the specified value, the processor  217  may start operation  805 . 
     In operation  805  according to an embodiment, the processor  217  may enter a low power mode. In an example, when the amount of power stored in the battery  251  is less than or equal to the specified value, the processor  217  may enter the low power mode. For example, when the identified amount of power of the battery  251  is about 25% and the specified value is about 30%, the processor  217  may enter the low power mode for saving power stored in the battery  251 . In an example, the specified value for entering the low power mode has been described as about 30%, but is not limited thereto. For example, the specified value may be about 25%. For another example, the specified value may be about 27%. 
     In operation  807  according to an embodiment, the processor  217  may execute a function of which an execution time point is adjusted, based on the first state, a folding state, and a second state in the low power mode. 
     According to an embodiment, the processor  217  may identify the first state, the folding state, and the second state in a state of entering the low power mode. 
     According to an embodiment, the processor  217  may execute at least one function of which an execution time point is adjusted, based on a result of the identification in operation  809 . For example, the processor  217  may not execute, in the low power mode, the first function (e.g., after switching to a second mode (e.g., a wake-up mode), releasing communication with the second electronic device  301  and establishing communication with the third electronic device  302 ) which is executed when the first electronic device  200  is mounted (e.g., whether in the first state) in the second electronic device  301 . In addition, for example, when the temple  250  is in an unfolded state in the low power mode, the processor  217  may execute the first function. In addition, when the first electronic device  200  is worn on the user&#39;s body in the low power mode, the processor  217  may execute the first function. In addition, the processor  217  may execute the second function (e.g., switching the display  213  to an on state and activating a sensor) and the third function (e.g. activating a camera and executing a vision algorithm) as well as the first function in the low power mode at an execution time point when the first electronic device  200  is worn on the user&#39;s body. That is, the processor  217  executes the first function, the second function, and the third function in the low power mode at an execution time point later than a time point when executed in the normal mode, so that power consumption of the battery  251  can be reduced. 
       FIG.  9    is a diagram illustrating an example method for displaying a screen on a front part of the display  213 , according to various embodiments. 
     Referring to  FIG.  9   , a processor (e.g., the processor  120  of  FIG.  1    or the processor  217  of  FIG.  2 A ) of a first electronic device (e.g., the electronic device  101  of  FIG.  1    or the first electronic device  200  of  FIG.  2 A ) may display a screen through a front part of a display (e.g., the display module  160  of  FIG.  1    or the display  213  of  FIG.  2 A ). 
     According to an embodiment, the processor  217  may determine whether to display information received from the third electronic device  302 , based on a first state and a folding state of the first electronic device  200 . 
     According to an embodiment, the information may include information related to a connection state with the third electronic device  302  and information on the amount of battery power of the third electronic device  302 , but is not limited thereto. For example, the information may include information (e.g., a title and a content type) related to a content being displayed on the third electronic device  302 , and may include information related to the amount of power stored in the battery  251  of the first electronic device  200 . 
     According to an embodiment, the processor  217  may determine that the first electronic device  200  is mounted in the second electronic device  301 , based on the identified first state. When the first electronic device is mounted in the second electronic device  301 , the processor  217  may receive power from the second electronic device  301  or transmit at least one of battery information and temperature information of the first electronic device  200  to the second electronic device  301 . 
     According to an embodiment, when the first electronic device  200  is not mounted in the second electronic device  301 , the processor  217  may release communication with the second electronic device  301  and establish communication with the third electronic device  302 . 
     According to an embodiment, the processor  217  may identify the folding state after establishing the communication with the third electronic device  302 . The processor  217  may identify a folding state of a temple (e.g., the temple  250  of  FIG.  2 A ) connected to a body (e.g., the body  210  of  FIG.  2 A ) through a folding detection sensor (not shown). When the temple  250  is in a folded state, the processor  217  may receive the information from the third electronic device  302  connected through a communication module (e.g., the communication module  219  of  FIG.  2 A ). For example, when the first electronic device  200  is not mounted in the second electronic device  301  and the temple  250  is in a folded state, the processor  217  may receive the information from the third electronic device  302 . 
     According to an embodiment, the processor  217  may output the received information through the front part of the display (e.g., at least one of a left display and a right display) included in the body  210 . When the temple  250  is in a folded state, the processor  217  may identify that the first electronic device  200  is not worn on a user&#39;s body. Accordingly, the processor  217  may invert image data to the left and right to output the image data to the display  213 . In addition, the left-right inversion operation of the image data may output image data previously stored in the first electronic device  200  and output, through the display  213 , image data received from the third electronic device  302  connected to the first electronic device  200 . For example, the processor  217  may display a model name of the third electronic device  302  and information  901  related to presence or absence of a connection on the right display. 
     In addition, according to an embodiment, the processor  217  may display information  903  on the amount of power stored in the battery  251  of the first electronic device  200  on the left display. 
       FIG.  10    is a diagram illustrating an example configuration of a wearable electronic device  1000  according to various embodiments. 
     In an embodiment, the first electronic device  200  of  FIG.  2 A  may include a part or all of the components configuring the wearable electronic device  1000  of  FIG.  10   .
