CROSS-REFERENCE TO RELATED APPLICATION(S) 
     This application is a continuation application, claiming priority under § 365(c), of an International application No. PCT/KR2022/017539, filed on Nov. 9, 2022, which is based on and claims the benefit of a Korean patent application number 10-2021-0153043, filed on Nov. 9, 2021, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety. 
    
    
     TECHNICAL FIELD 
     The disclosure relates to a method and an apparatus capable of supporting various display methods using an electronic device and/or a glasses-type wearable electronic device (e.g., AR glasses) in augmented reality (AR). 
     BACKGROUND ART 
     Recently, research and development of extended reality (XR) technologies such as virtual reality (VR), augmented reality (AR), and/or mixed reality (MR) have been conducted. VR, AR, and/or MR technologies have been used in various fields (e.g., entertainment, infotainment, smart homes, and/or smart factories), and hardware parts and/or software parts of an electronic device for the same are actively being researched and developed. 
     For example, a wearable electronic device may superimpose, through an application related to an AR service, a variety of digital content (e.g., virtual images) on the real world (or overlay the real world with the digital content) alone (e.g., a standalone method) or in association with at least two devices (e.g., a tethered method), thereby providing one image through a display of the wearable electronic device. For example, recently, AR environments such as a tethered AR method in which an electronic device (e.g., a smartphone) and a wearable electronic device are connected to provide virtual content produced by the electronic device through a display of the wearable electronic device and a standalone AR method in which a wearable electronic device independently produces virtual content without connection with an electronic device and provides the same through a display have been implemented. 
     As described above, in line with the recent technological development of AR services, the number of users using the AR services is increasing, and thus user needs are also increasing. For example, users who use AR services have an increasing demand for selecting and displaying content more accurately and intuitively in an AR environment. 
     The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

     The wearable electronic device  301  may be worn on a user&#39;s face to provide an image (e.g., an augmented reality image, a mixed reality image, and/or a virtual reality image) to the user. According to an embodiment, the wearable electronic device  301  may provide an AR service in which virtual information (or a virtual object) is added to at least a portion of a real space (or environment). For example, the wearable electronic device  301  may provide the user with virtual information overlaid on the real space corresponding to the field of view (FOV) of the wearer. 
     Referring to  FIG.  3   , the wearable electronic device  301  may include a glass member (or window members)  310  disposed at positions corresponding to both eyes (e.g., left and right eyes) of the user, a main frame (or body part)  340  for fixing the glass member  310 , support frames (or support members)  350  connected at both ends of the main frame  340  to be mounted on the user&#39;s ears, and a camera module  380  (e.g., a photographing camera). 
     The glass member  310  may include a first glass  320  corresponding to the user&#39;s left eye and a second glass  330  corresponding to the user&#39;s right eye. According to an embodiment, the glass member  310  may be supported by the main frame  340 . For example, the glass member  310  may be fitted into the opening formed in the main frame  340 . The AR image emitted from a display module (e.g., the display module  520  in  FIG.  5   ) may be projected onto the glass member  310 . 
     A waveguide or a transparent waveguide may be formed in at least a portion of the glass member  310 . The waveguide may serve to guide the AR image emitted from the display module to the user&#39;s eyes. A detailed description of the waveguide according to embodiments of the disclosure will be made with reference to the description related to the first glass  320  and the second glass  330  in  FIG.  4   . 
     Although the glass member  310  is implemented such that the first glass  320  and the second glass  330  are separated to correspond to the user&#39;s left and right eyes, respectively, as illustrated in  FIG.  3   , according to another embodiment of the disclosure, the glass member  310  may be implemented in the form of one glass, instead of separating the first glass  320  and the second glass  330 . 
     The main frame  340  and the support frame  350  may be implemented in the form of glasses. 
     The main frame  340  may have a structure capable of being at least partially mounted on the user&#39;s nose. The main frame  340  may support the glass member  310 . The main frame  340  may be formed of a synthetic resin material. The glass member  310  may be fitted into the opening formed in the main frame  340 , so that the main frame  340  may support the glass member  310 . 
     The support frame  350  may include a first support frame  360  mounted on the ear in the first direction (e.g., the left ear) and a second support frame  370  mounted on the ear in the second direction (e.g., the right ear). For example, the main frame  340  and the support frame  350  (e.g., the first support frame  360  and the second support frame  370 ) may be coupled to be folded through a hinge (not shown). 
     The support frame  350  may be rotatably coupled to the main frame  340 . The support frame  350  may include a first support frame  360  and a second support frame  370 . The first support frame  360  may be coupled to the main frame  340  on the left side (e.g., a first direction) of the main frame  340  when viewed from the direction ‘A’. The second support frame  370  may be coupled to the main frame  340  on the right side (e.g., a second direction) of the main frame  340  when viewed from the direction ‘A’. 
     The support frame  350  may be fixed to the main frame  340 . For example, the first support frame  360  coupled to the left side of the main frame  340  and the second support frame  370  coupled to the right side of the main frame  340  may be coupled to each other. The support frame  350  coupled to both sides of the main frame  340  may form a ring shape to be worn to be fitted to the user&#39;s head. In addition, the support frame  350  may be modified into various shapes in which the wearable electronic device  301  is able to be worn on the user&#39;s face. 
     The support frame  350  may be formed to be supported by the user&#39;s ear. For example, the wearable electronic device  301  may be worn on the user&#39;s face in such a way that the support frame  350  coupled to the main frame  340  is supported by the user&#39;s ear. The support frame  350  may rotate relative to the main frame  340 . The support frame  350  may rotate to approach the main frame  340 , thereby reducing the volume of the wearable electronic device  301 . 
     The display module (e.g., the display module  520  in  FIG.  5   ) may output an AR image produced by the processor  120  of the electronic device  101  or a processor (e.g., the processor  590  in  FIG.  5   ) of the wearable electronic device  301 . When the display module produces and project an AR image onto the glass member  310 , the objects included in the AR image may be combined with the visible light L incident from the front (e.g., the direction in which the user views) through the glass member  310 , thereby implementing AR. The display module may be a very small projector (e.g., a micro-projector or a pico-projector). For example, the display module may be a laser scanning display (LSD), a digital micro-mirror display (DMD), and/or liquid crystal-on-silicon (LCoS). According to an embodiment of the disclosure, the display module may be a transparent display. In this case, the light-emitting device included in the display module may be directly disposed on the glass member  310 . In addition, the display module may be various display devices for implementing AR. 
     A pair of glass members  310 , a pair of support frames  350 , and/or a pair of display modules (e.g., the display module  520  in  FIG.  5   ) may be provided to correspond to the user&#39;s left and right eyes. For example, the glass member  310  may include a first glass  320  and a second glass  330 , and the support frame  350  may include a first support frame  360  and a second support frame  370 . According to various embodiments of the disclosure, some of the above-described elements may be different between a configuration corresponding to the left eye and a configuration corresponding to the right eye. 
     The camera module  380  may include, for example, a photographing camera (e.g., a front photographing camera). For example, the camera module  380  may be implemented to be disposed in the main frame  340  so as to photograph a subject in the front (or the front that the user views) of the wearable electronic device  301 . The camera module  380  may be disposed in the central portion (or center point) between the first glass  320  and the second glass  330  in the main frame  340  so as to photograph the front of the main frame  340 . The front of the main frame  340  may indicate a direction in which the user wearing the wearable electronic device  301  views. The wearable electronic device  301  may include a plurality of other cameras, as well as the camera module  380 , and the camera module  380  and the plurality of other cameras will be described in detail with reference to  FIG.  4   .

According to an embodiment, the wearable electronic device  301  may project or display a virtual object onto the first glass  320  and/or the second glass  330 , so that the user may view the real world recognized through the first glass  320  and/or the second glass  330  of the wearable electronic device  301 , on which at least one virtual object is superimposed. 
     Referring to  FIG.  4   , the wearable electronic device  301  may include a main frame (or body part)  340 , a support frame (e.g., a first support frame  360  and a second support frame  370 ), and a hinge (e.g., a first hinge  440 - 1  and a second hinge  440 - 2 ). 
     The main frame  340  and the support frame (e.g., the first support frame  360  and/or the second support frame  370 ) may have various elements of the wearable electronic device  301  mounted thereto. The main frame  340  and the support frames  360  and  370  may be operatively coupled through the hinges  440 - 1  and  440 - 2 .

According to another embodiment of the disclosure, the hinges  440 - 1  and  440 - 2  of the wearable electronic device  301  may be omitted. For example, the support frames  360  and  370  may be directly coupled to the main frame  340  to be fixed. 
     The main frame  340  may include glasses (e.g., a first glass  320  and a second glass  330 ) corresponding to both eyes (e.g., left and right eyes) of the user, display modules (e.g., a first display module  414 - 1  and a second display module  414 - 2 ), waveguides (e.g., a first waveguide  420  and a second waveguide  430 ), a camera module  380  (e.g., a photographing camera or a front photographing camera), recognition cameras (e.g., a first recognition camera  411 - 1  and a second recognition camera  411 - 2 ), eye tracking cameras (e.g., a first eye tracking camera  412 - 1  and a second eye tracking camera  412 - 2 ), one or more microphones (e.g., a first microphone  441 - 1 , a second microphone  441 - 2 , and/or a third microphone  441 - 3 ), and one or more lighting members (e.g., a first lighting member  442 - 1  and/or a second lighting member  442 - 2 ). 
     The wearable electronic device  301  may display a variety of information by projecting light produced by the display modules  414 - 1  and  414 - 2  onto the glasses  320  and  330 . For example, the light produced by the first display module  414 - 1  may be projected onto the first glass  320 , and the light produced by the second display module  414 - 2  may be projected onto the second glass  330 . At least a portion of the first glass  320  and the second glass  330  may be formed of a transparent material (e.g., a transparent member). 
     The first glass  320  (or a first transparent member) corresponding to the user&#39;s left eye may be coupled to the first display module  414 - 1 , and the second glass  330  (or a second transparent member) corresponding to the user&#39;s right eye may be coupled to the second display module  414 - 2 . The first glass  320  and the second glass  330  may be formed of a glass plate, a plastic plate, and/or a polymer, and may be made transparent or translucent. 
     The display modules (e.g., the first display module  414 - 1  and the second display module  414 - 2 ) may include a liquid crystal display (LCD), a digital micro-mirror device (DMD), liquid crystal-on-silicon (LCoS), an organic light-emitting diode (OLED), or a micro light-emitting diode (micro LED). 
     The first glass  320  and the second glass  330  may include a condensing lens and/or a waveguide (or a transparent waveguide) (e.g., a first waveguide  420  and a second waveguide  430 ). The waveguides  420 ,  430  may be at least partially positioned in a portion of the glasses  320  and  330 . The first waveguide  420  may be partially positioned on the first glass  320 . The second waveguide  430  may be partially positioned on the second glass  330 . 
     The waveguides  420  and  430  may serve to transmit the light produced by the display modules  414 - 1  and  414 - 2  to the user&#39;s eyes. Light emitted from the display modules  414 - 1  and  414 - 2  may be incident on one surface (or one end) of the glasses  320  and  330 . The light incident on one surface of the glasses  320  and  330  may be transmitted to the user through waveguides  420  and  430  formed (or positioned) in the glasses  320  and  330 . 
     The waveguides  420  and  430  may be made of glass, plastic, or polymer, and may include nanopatterns formed on one surface inside or outside the same. The nanopattern may include a polygonal or curved grating structure. The light incident on one surface of the glasses  320  and  330  may be transmitted or reflected by the nano-pattern inside the waveguides  420  and  430  to be transmitted to the user. The waveguides  420  and  430  may include at least one of at least one diffractive element (e.g., a diffractive optical element (DOE) or a holographic optical element (HOE)) or a reflective element (e.g., a reflective mirror). The waveguides  420  and  430  may guide the light emitted from the display modules  414 - 1  and  414 - 2  (e.g., light sources) to the user&#39;s eyes using at least one diffractive element or reflective element. 
     The diffractive element may include an input optical member/output optical member (not shown). The input optical member may indicate an input grating area, and the output optical member (not shown) may indicate an output grating area. The input grating area may serve as an input terminal that diffracts (or reflects) the light output from the display modules  414 - 1  and  414 - 2  (e.g., micro LEDs) to transmit the same to the glasses (e.g., the first glass  320  and the second glass  330 ). The output grating area may serve as an outlet that diffracts (or reflects) the light transmitted to the glasses (e.g., the first glass  320  and the second glass  330 ) of the waveguides  420  and  430  to the user&#39;s eyes. 
     The reflective element may include a total reflection optical element or a total reflection waveguide for total internal reflection (TIR). Total internal reflection is one way of guiding light in which an incident angle is formed such that light (e.g., a virtual image) input through the input grating area is reflected about 100% by one surface (e.g., a specified surface) of the waveguides  420  and  430 , thereby transmitting about 100% of light to the output grating area. 
     The light emitted from the display modules (e.g.,  414 - 1  and  414 - 2 ) may be guided to the waveguides  420  and  430  through the input optical member. The light travelling inside the waveguides  420  and  430  may be guided to the user&#39;s eyes through the output optical member. 
     The display modules  414 - 1  and  414 - 2  may include a plurality of panels (or display areas), and the plurality of panels may be positioned on the glasses  320  and  330 . At least a portion of the display modules  414 - 1  and  414 - 2  may be formed of a transparent element. The user may recognize the actual space behind the display modules  414 - 1  and  414 - 2  through the display modules  414 - 1  and  414 - 2 . The display modules  414 - 1  and  414 - 2  may display a virtual object (or virtual information) in at least a portion of the transparent element such that it appears to the user that the virtual object is added to at least a portion of the real space. If the display modules  414 - 1  and  414 - 2  are transparent micro LEDs, the configuration of the waveguides  420  and  430  may be omitted from the glasses  320  and  330 . 
     The wearable electronic device  301  may include a plurality of cameras (e.g., a first camera, a second camera, and a third camera). For example, the first camera (e.g., the camera module  380  in  FIG.  3   ) may be a photographing camera  380  (e.g., an RGB camera) for photographing an image corresponding to the field of view (FoV) of the user and/or measuring a distance to an object. The second camera may be eye tracking camera (eye tracking camera module)  412 - 1  or  412 - 2  for identifying the direction of a user&#39;s gaze. The third camera may be a recognition camera (gesture camera module)  411 - 1  or  411 - 2  for recognizing a certain space. 
     The photographing camera  380  may photograph the front direction of the wearable electronic device  301 , and the eye tracking cameras  412 - 1  and  412 - 2  may photograph a direction opposite the photographing direction of the photographing camera  380 . For example, the first eye tracking camera  412 - 1  may partially photograph the user&#39;s left eye, and the second eye tracking camera  412 - 2  may partially photograph the user&#39;s right eye. The wearable electronic device  301  may display a virtual object (or virtual information) related to an AR service, based on image information related to the real space obtained through the photographing camera  380 . 
     According to an embodiment of the disclosure, the wearable electronic device  301  may display virtual objects, based on the display module disposed to correspond to both eyes of the user (e.g., a first display module  414 - 1  corresponding to the left eye and/or a second display module  414 - 2  corresponding to the right eye). According to another embodiment of the disclosure, the wearable electronic device  301  may display virtual objects, based on predetermined configuration information (e.g., resolution, frame rate, brightness, and/or display area). 
     The photographing camera  380  may include a high-resolution camera such as a high-resolution (HR) camera and/or a photo video (PV) camera. For example, the photographing camera  380  may utilize an autofocus function and an optical image stabilizer (OIS) function to obtain high-quality images. The photographing camera  380  may be implemented as a global shutter (GS) camera and a rolling shutter (RS) camera in addition to a color camera. 
     The eye tracking cameras  412 - 1  and  412 - 2  may detect the user&#39;s gaze direction (e.g., eye movement). For example, the eye tracking cameras  412 - 1  and  412 - 2  may detect the user&#39;s pupil and track the gaze direction. The tracked gaze direction may be used to move the center of a virtual image including a virtual object in response to the gaze direction. For example, the eye tracking cameras  412 - 1  and  412 - 2  may use a global shutter (GS) camera to detect the pupil and track the rapid pupil movement without dragging of a screen, and the performance and specifications may be substantially the same between the eye tracking cameras  412 - 1  and  412 - 2 . 
     The recognition cameras  411 - 1  and  411 - 2  may detect a user gesture within a predetermined distance (e.g., a predetermined space) and/or a predetermined space. The recognition cameras  411 - 1  and  411 - 2  may be used for 3 DoF or 6 DoF head tracking, hand detection, and/or hand tracking. For example, the recognition cameras  411 - 1  and  411 - 2  may be utilized to perform spatial recognition for 6 DoF and a simultaneous localization and mapping (SLAM) function through depth imaging. The recognition cameras  411 - 1  and  411 - 2  may be utilized for a gesture recognition function for recognizing a user gesture. The recognition cameras  411 - 1  and  411 - 2  may include cameras including GS. For example, recognition cameras  411 - 1  and  411 - 2  may include a camera including GS, which has less screen drag (or reduced RS phenomenon) like RS (rolling shutter) cameras, to detect and track quick hand movements and/or fine finger movements.

The standalone method may include a method in which the AR service is processed by the wearable electronic device  301 . The tethered method may include a method in which the AR service is processed by the electronic device  101  and provided by interworking between the electronic device  101  and the wearable electronic device  301 . For example, in the case of the tethered method, the processing entity of the content  710  may be the electronic device  101  that may operate to display the content  710  in the first display mode. As another example, in the case of the standalone method, the processing entity of the content  710  may be the wearable electronic device  301  that may operate to display the content  710  in the second display mode. 
     The display mode determined according to the processing entity may vary depending on whether the profile of the content  710  to be provided corresponds to a prespecified profile. For example, if the content  710  to be provided corresponds to a specified profile, the display mode (e.g., the second display mode) using the virtual space may be determined, regardless of whether the processing entity is the electronic device  101  or the wearable electronic device  301 . The profile may include identification information related to whether or not the content  710  is information related to privacy and/or whether the content is an application category (e.g., phone, personal SNS, and/or finance) specified to be protected by the user. The profile for determining the display mode may be variously pre-configured in the electronic device  101  or the wearable electronic device  301  by the user. 
     Referring to  FIG.  7 C ,  FIG.  7 C  shows an example in which the processing entity is the electronic device  101 . For example,  FIG.  7 C  shows an example of the first display mode in which the content  710  is continuously displayed through the display mode  160  of the electronic device  101  in the case where the AR service is provided in the tethered method and/or where the content  710  to be provided does not correspond to a specified profile. For example, in the case where the electronic device  101  performs processing of the content  710  an application corresponding to the content  710  being executed in relation to AR services or, the current screen display of the wearable electronic device  301  may be stopped, and the content  710  being displayed through the AR screen may be displayed through the display module  160  of the electronic device  101 . For example, the electronic device  101  may display the content  710  through the entirety or at least a portion of the display area of the display module  160  of the electronic device  101  in the first display mode. In an embodiment, the stoppage of the screen display is, for example, the state in which the wearable electronic device  301  is taken off and may include, for example, the state in which the display module  520  or the wearable electronic device  301  is powered off. 
     The first display mode is a mode for displaying the content  710 , provided through the AR screen, on the display module  160  of the electronic device  101  and may be provided in various ways depending on a user interaction according to the form factor of the electronic device  101 . 
     As illustrated in example &lt; 705 A&gt; in  FIG.  7 C , if the form factor of the electronic device  101  is a bar type or if the form factor is a rollable type but there is no rollable activation interaction (e.g., in a closed (or slide-in) state), the electronic device  101  may display the content  710  through a specified display area of the display module  160 . According to an embodiment, the electronic device  101  may provide the entire area or at least a partial area of the display module  160  as an active window  720  for displaying the content  710 . 
     As illustrated in example &lt; 705 B&gt; in  FIG.  7 C , if the form factor of the electronic device  101  is a rollable type and if the display module  160  is extended by a rollable activation interaction  703  such that an extension area B is further provided in addition to a default area A, the electronic device  101  may display the content  710  through a specified display area of the display module  160 . 
     The electronic device  101  may maintain the existing display state of the default area A of the display module  160  and provide the extension area B, which is further extended, as an active window  730  for displaying the content  710 . The degree of extending the extension area B may vary depending on at least one of the number of pieces of content  710 , the type of content  710 , the display method of the content  710  (e.g., a landscape mode or a portrait mode), or a display size of the content  710 . 
     According to another embodiment of the disclosure, since the user interaction  703  reflects a clear intention of the user for screen extension, the electronic device  101  may provide the entire area (e.g., default area A+extension area B) including the default area A and the extension area B of the display module  160  as an active window  740  for displaying the content  710 . 
     Referring to  FIG.  7 D ,  FIG.  7 D  shows an example in which the processing entity is the wearable electronic device  301 . For example,  FIG.  7 D  shows an example of the second display mode in which the content  710  is continuously displayed through the display module  520  of the wearable electronic device  301  if an AR service is provided in the standalone method and/or if an AR service is provided in the tethered method but the content  710  to be provided corresponds to a specified profile. For example, if the wearable electronic device  301  performs processing of the content  710  or an application corresponding to the content  710  being executed in relation to AR services, or if the content  710  to be provided corresponds to a specified profile, the wearable electronic device  301  may perform the following. Mapping (e.g., texture mapping or lock) content  710  may be displayed in a default area A of the electronic device  101  positioned in the real space  700  displayed in the AR screen, in an extension area B of the electronic device  101 , and/or in a virtual area V produced adjacent to the electronic device  101  through the display module  520  of the wearable electronic device  301 . The wearable electronic device  301  may map and display the content  710  through the entirety or at least a portion of the default area A, the extension area B, the entire area (e.g., default area A+extension area B), and/or the virtual area V of the electronic device  101  in the virtual space according to the second display mode. 
     The second display mode is a mode for displaying the content  710  through a virtual space provided through the display module  520  of the wearable electronic device  301  and may be provided in various ways depending on an user interaction on the AR screen according to the form factor of the electronic device  101 . The second display mode may be a mode in which the content  710 , provided by being mapped to a real object in the real space  700  through the AR screen, is to be mapped and displayed on the display module  160  of the electronic device  101  on the AR screen. 
     As illustrated in example &lt; 715 A&gt; in  FIG.  7 D , if the form factor of the electronic device  101  is a bar type or if the form factor is a rollable type but there is no rollable activation interaction (e.g., in a closed (or slide-in) state), the wearable electronic device  301  may map and display content  710  in the default area A of the display module  160  of the electronic device  101 , which is recognized from the real space  700  provided through the display module  520 , and/or in the virtual area V that is virtually produced based on the default area A. 
     The wearable electronic device  301  may map the default area A and/or the virtual area V of the electronic device  101  recognized from the real space  700 , provided through the display module  520 , as active windows  760  and  770  for displaying the content  710 . The content  710  mapped to the default area A is provided through the AR screen and may not be displayed through the display module  160  of the electronic device  101  in the real space. In an embodiment, the virtual area V may indicate a virtual display area that is digitally produced corresponding to the default area A of the electronic device  101 , based on the recognized electronic device  101 , and is displayed only through the display module  520  of the wearable electronic device  301 . 
     For example, the virtual area V may not be an extension area resulting from actual extension of the electronic device  101 . The user may input only a gesture for extension, instead of substantially extending the electronic device  101 , and a virtual extension area may be provided in response thereto by replacing the area corresponding to an actually extension area by a virtual area V. As described above, the content  710  provided through the second display mode may be provided only by the AR screen provided through the display module  520  of the wearable electronic device  301 , and may be viewed and/or controlled only by the user wearing the wearable electronic device  301 , but may be invisible to other users in the real world. 
     As illustrated in example &lt; 715 B&gt; in  FIG.  7 D , if the form factor of the electronic device  101  is a rollable type and if the display module  160  is extended by a rollable activation interaction  703  such that an extension area B is further provided in addition to a default area A, the wearable electronic device  301  may display the content  710  through a specified display area of the display module  160  of the electronic device  101 . 
     The wearable electronic device  301  may maintain the existing display state of the default area A of the electronic device  101  in the real space  700  provided through the display module  520 , configure the extension area B, which is further extended, as an active window  780  for displaying the content  710 , and may map the content  710  to the active window  780 , thereby providing the same. According to another embodiment of the disclosure, since the user interaction  703  reflects a clear intention of the user for screen extension, the wearable electronic device  301  may configure the entire area (e.g., default area A+extension area B) including the default area A and the extension area B of the electronic device  101  in the real space  700  provided through the display module  520  as an active window  790  for displaying the content  710  and map the content  710  to the active window  790 , thereby providing the same. 
     As described above, the content  710  provided through the second display mode may be provided only by the AR screen provided through the display module  520  of the wearable electronic device  301 , and may be viewed and/or controlled only by the user wearing the wearable electronic device  301 , but may be invisible to other users in the real world. 
     Although the AR service is provided in the tethered method, in the case where the content  710  to be provided corresponds to a specified profile, the electronic device  101  may provide the second display mode by an operation corresponding to the operation of the wearable electronic device  301 , which was described with reference to  FIG.  7 D . The electronic device  101  may obtain a variety of information for the second display mode from the wearable electronic device  301  and, based on the obtained information, transmit data related to an active window according to the second display mode (e.g., coordinate, position, and/or spatial information) and information to be displayed on the active window to the wearable electronic device  301  such that the wearable electronic device  301  provides the second display mode. 
     An augmented reality (AR) providing device (e.g., the electronic device  101  or the wearable electronic device  301 ) for AR services according to an embodiment of the disclosure may include a display module (e.g., the display module  160  of the electronic device  101  or the display module  520  of the wearable electronic device  301 ) and a processor (e.g., the processor  120  of the electronic device  101  or the processor  590  of the wearable electronic device processor  301 ). The processor  120  or  590  may operate to provide content through an AR screen. The processor may operate to detect a specified external object through the AR screen while providing the content. The processor may operate to determine a display mode for providing the content, based on detection of the specified external object. The processor may operate to control display of the content through a display module of the specified external object (e.g., the display module  160  of the electronic device  101 ), based on the determined display mode. The processor may operate to control display of the content through a virtual display area associated with the specified external object on the AR screen, based on the determined display mode. 
     The content may be produced by the AR providing device for AR services and provided through the display module of the AR providing device (e.g., the display module  160  of the electronic device  101  or the display module  520  of the wearable electronic device  301 ), or may be produced by the AR providing device, transmitted to an external device connected through specified communication, and provided through a display module of the external device (e.g., the display module  160  of the electronic device  101  or the display module  520  of the wearable electronic device  301 ). 
     The processor  120  or  590  may operate to detect a specified interaction through the AR screen, determine whether a target device processing the content is an electronic device  101  or a wearable electronic device  301 , based on the detection of the specified interaction, if the target device is determined to be the electronic device  101 , determine a first display mode in which the content on the AR screen switches to be displayed through the electronic device  101 , and if the target device is determined to be the wearable electronic device  301 , determine a second display mode in which the content is mapped to the electronic device  101  and displayed on the AR screen. 
     Based on the determination of the first display mode, the processor  120  or  590  may operate to perform control to stop displaying a screen of the wearable electronic device  301  and control the display of the content being displayed through the AR screen, based on a display area corresponding to a display module  160  of the electronic device  101 . 
     The processor  120  or  590  may operate to configure a specified active window for the content being displayed on the AR screen through a default area and/or an extension area of the display module  160  of the electronic device  101 , and control display of the content based on the configured active window. 
     The processor  120  or  590  may operate to control content display based on a virtual display area associated with the electronic device  101  on an AR screen provided through a display module  590  of the wearable electronic device  301 , based on the determination of the second display mode. 
     Based on the determination of the second display mode, the processor  120  or  590  may operate to map and display the content, based at least on a default area of the electronic device  101  positioned in a real space displayed on the AR screen through the display module  590  of the wearable electronic device  301 , an extension area of the electronic device  101 , and/or a virtual area produced adjacent to the electronic device  101 . 
     Based on the determination of the second display mode, the processor  120  or  590  may operate to configure a virtual area corresponding to an extension area of the display module  160  of the electronic device  101  to correspond to the extension area of the electronic device  101 , configure a specified active window for the content being displayed on the AR screen through the default area and/or the extension area of the display module  160  of the electronic device  101 , and control content display through content mapping based on the configured active window. 
     If the processor  120  or  590  provides the content according to the second display mode, the content mapped to the AR screen may be provided only through a display area associated with the electronic device  101  on the AR screen, instead of being displayed through the display module  160  of the electronic device  101  in the real space. 
     The specified interaction may include a first interaction in which the electronic device  101  enters the real space of the AR screen provided through the display module  590  of the wearable electronic device  301 , a second interaction in which a user inputs a specified gesture using the electronic device  101  after the entry of the electronic device  101 , and/or a third interaction in which the user inputs a specified menu manipulation gesture through the electronic device  101  on the AR screen after the entry of the electronic device. 
     The processor  120  or  590  may operate to determine whether or not the content corresponds to a specified profile when determining the target device processing the content and, if the content corresponds to the specified profile, determine the second display mode so as to provide content of the specified profile through the AR screen, regardless of the target device processing the content. 
     An augmented reality (AR) providing device (e.g., the electronic device  101  or the wearable electronic device  301 ) for AR services according to an embodiment of the disclosure may include a display module (e.g., the display module  160  of the electronic device  101  or the display module  520  of the wearable electronic device  301 ) and a processor (e.g., the processor  120  of the electronic device  101  or the processor  590  of the wearable electronic device processor  301 ). The processor  120  or  590  may operate to display content through the display module. The processor may operate to recognize an external device corresponding to the external object from the AR screen while displaying the content through the display module. The processor may operate to monitor a change in state of the external device if the external device is a specified external device. The processor may operate to determine a processing entity related to the content, based on identifying a change in the state of the external device. The processor may operate to determine the display mode of the content, based on the determined processing entity. The processor may operate to display the content on the AR screen through a display module, based on the determined display mode. The processor may operate to control the external device to display the content through the display module of the external device, based on the determined display mode. 
     Operation methods of the electronic device  101  and the wearable electronic device  301  according to various embodiments of the disclosure are described below. 
     Operations performed by the electronic device  101  may be executed by the processor  120  of the electronic device  101  including various processing circuits and/or executable program elements. The operations performed by the electronic device  101  may be stored in the memory  130  and executed by instructions that, when executed, cause the processor  120  to operate. 
     The operations performed by the wearable electronic device  301  described below may be executed by the processor  590  of the wearable electronic device  301  including various processing circuits and/or executable program elements. Operations performed by the wearable electronic device  301  may be stored in the memory  550  and executed by instructions that, when executed, cause the processor  590  to operate. 
     The operations of the electronic device  101  and the wearable electronic device  301  may be distinguished depending on a processing entity according to whether the AR service is a standalone method or a tethered method, and the operation of displaying content by operating the display mode of the disclosure may be similar or the same therebetween, excluding the operation of performing data communication as necessary. For example, the electronic device  101  and the wearable electronic device  301  may perform a series of operations of rapidly switching between screens in the situation of using AR, enabling content movement between the electronic device  101  and the wearable electronic device  301 , configuring an active window, based on a processing entity and/or a specified profile, and displaying content through a corresponding active window. 
       FIG.  8    is a flowchart illustrating a method of operating an electronic device or a wearable electronic device according to an embodiment of the disclosure. 
       FIG.  9    is a diagram illustrating an example of a specified interaction for triggering the operation according to an embodiment of the disclosure. 
       FIG.  8    shows an example of an operation of providing content through an electronic device  101  or a wearable electronic device  301  depending on a display mode (e.g., a first display mode or a second display mode) for displaying content, based on a specified interaction, in a situation in which the electronic device  101  or the wearable electronic device  301  provides an AR service according to a tethered method or a standalone method. In an embodiment, the operation illustrated in  FIG.  8    may be performed by the electronic device  101  or the wearable electronic device  301 , and, in the following description of  FIG.  8   , the electronic device  101  or the wearable electronic device  301  will be referred to as an AR providing device for convenience of description. The electronic device  101  and the wearable electronic device  301  may further include an operation of receiving, processing, and transmitting related data for an AR service depending on the entity that performs the operation, and a description thereof will be made with reference to the drawings to be described later. 
     Referring to  FIG.  8   , in operation  801 , an AR providing device (e.g., the electronic device  101  or the wearable electronic device  301 ) or a processor of the AR providing device (e.g., the processor  120  of the electronic device  101  or the processor  590  of the wearable electronic device  301 ) may provide content through a display module  520  of the wearable electronic device  301 . The AR providing device, the wearable electronic device  301  may be in the state of being worn on the user and displaying at least one piece of content (or virtual information) superimposed on at least a portion of a real space on an AR screen through the display module  520  of the wearable electronic device  301 . 
     For example, the wearable electronic device  301  may superimpose at least one piece of content in the real space corresponding to the field of view of the user, thereby providing the content to the user. The wearable electronic device  301  may display, through the display module  520  of the wearable electronic device  301 , content that is directly produced for the AR service by the wearable electronic device  301  (e.g., produced based on stored or processed data) or content that is produced by the electronic device  101  and obtained from the electronic device  101  through specified communication. According to an embodiment, the user may browse AR content provided through the display module  520  of the wearable electronic device  301 . 
     In operation  803 , the AR providing device may detect a specified interaction through the AR screen. In an embodiment, an example of a specified interaction is shown in  FIG.  9   . 
     Referring to  FIG.  9   , the specified interaction may include a first interaction (example  901 ) of recognizing the electronic device  101  entering the real space of the AR screen provided through the display module  520  of the wearable electronic device  301 , a second interaction (example  903 ) of recognizing a specified gesture (e.g., a slide-out gesture or a rollable extension gesture) input by a user using the electronic device  101  after the entry of the electronic device  101 , or a third interaction (example  905 ) of recognizing a specified menu manipulation gesture (e.g., a touch input) input by the user through the electronic device  101  on the AR screen after the entry of the electronic device  101 . 
     The second interaction may include a gesture of substantially extending the extension area of the electronic device  101 . In another embodiment, the second interaction may not be a substantial extension of the extension area of the electronic device  101 . For example, the user may input only an extending gesture without substantially extending the electronic device  101 , and the AR providing device may recognize the user&#39;s gesture to identify the second interaction. The AR providing device may detect a user&#39;s gesture according to the second interaction and/or the third interaction, based on the user hand detecting and/or hand tracking on the AR screen. 
     The example of the specified interaction is intended only to help understanding of the disclosure and is not intended to limit the embodiment of the disclosure. For example, the second interaction in the specified interaction may include a real extension or virtual extension trigger for the electronic device  101  and include, for example, an input to a specified hardware button of the electronic device  101  for extension of the extension area (e.g., a click input or a long-press input) and an input to a specified software button displayed through the display module  160  of the electronic device  101  for extension of the extension area (e.g., a touch input or a long-press input). The second interaction may include various specified inputs as an extension trigger capable of substantially or virtually extending the extension area of the electronic device  101 . 
     Referring back to  FIG.  8   , in operation  805 , the AR providing device may determine an operation entity for processing the content. The operation entity for processing may be determined differently depending on a method of providing an AR service. For example, in the tethered method, content may be produced by the electronic device  101  and provided to the wearable electronic device  301 , and the processing entity of the content may be the electronic device  101 . As another example, in the case of the standalone method, content may be directly produced and provided by the wearable electronic device  301 , and the processing entity of the content may be the wearable electronic device  301 . 
     For example, in the tethered method, the electronic device  101  has the control right of the overall operation for the AR service, the AR service is controlled by the electronic device  101 , and the wearable electronic device  301  may obtain content from the electronic device  101 , thereby providing the content to the user. As another example, in the standalone method, the wearable electronic device  301  has the control right of the overall operation for the AR service, and the AR service is controlled by the wearable electronic device  301 , and the content directly produced by the wearable electronic device  301  may be provided. The AR providing device may further determine whether or not the content to be provided corresponds to a specified profile, in addition to the operation entity for processing. For example, the AR providing device may operate to preferentially provide content of a specified profile through the AR screen, regardless of the processing entity. An operation using the specified profile will be described later. 
     In operation  807 , the AR providing device, based on the result of determining the operation entity, may determine whether a target device for displaying content is the electronic device  101  or the wearable electronic device  301 . 
     If it is determined that the target device is the electronic device  101  in operation  807  (e.g., “Yes” in operation  807 ), the AR providing device may determine a first display mode in operation  809 . If the operation entity is the electronic device  101 , the AR providing device may determine a first display mode in which the content on the AR screen switches to be displayed through the electronic device  101 . 
     In operation  811 , based on the determination of the first display mode, the AR providing device may perform processing to display content, based on a display area corresponding to the display module  160  of the electronic device  101 . If the electronic device  101  performs processing of content or an application corresponding to the content being executed in relation to AR services, the AR providing device may operate to stop displaying the current screen of the wearable electronic device  301  (e.g., turn off the display module  520  or the wearable electronic device  301  in the state in which the wearable electronic device  301  is taken off) and display the content being displayed through the AR screen through the display module  160  of the electronic device  101 . 
     If the processing entity related to the content is the electronic device  101 , the AR providing device may operate to stop displaying the AR screen of the wearable electronic device  301 , configure a specified active window (e.g., a window based on a default area, a window based on an extension area, or a window based on the entire area) for the content being displayed on the AR screen through a default area and/or an extension area of the display module  160  of the electronic device  101 , and display the content, based on the configured active window. 
     If the processing entity is the electronic device  101 , the AR providing device may configure an active window to correspond to a form factor (e.g., a bar type or rollable type) of the electronic device  101 . For example, in the case of the bar-type electronic device  101 , the AR providing device may configure an active window based on the default area. As another example, in the case of the rollable type electronic device  101 , the AR providing device may configure an active window based on at least one of the default area, a partially extension area, the entire extension area, or the entire area. 
     If it is determined that the target device is the wearable electronic device  301  in operation  807  (e.g., “No” in operation  807 ), the AR providing device may determine a second display mode in operation  813 . For example, if the operation entity is the wearable electronic device  301 , the AR providing device may determine a second display mode in which the content on the AR screen is mapped to the actual electronic device  101  on the AR screen and displayed. 
     In operation  815 , based on the determination of the second display mode, the AR providing device, may perform processing to display the content, based on a virtual display area associated with the electronic device  101 , on the AR screen provided through the display module  520  of the wearable electronic device  301 . If the wearable electronic device  301  performs processing of the content or an application corresponding to the content being executed in relation to AR services, or if the content to be provided corresponds to a specified profile, the AR providing device may process content display, based on the determination of the second display mode. The AR providing device may operate to map (e.g., texture mapping) and display the content, based at least on a default area of the electronic device  101  positioned in the real space displayed on the AR screen through the display module  520  of the wearable electronic device  301 , an extension area of the electronic device  101 , and/or a virtual area produced adjacent to the electronic device  101 . For example, the AR providing device may display the content through the entirety or at least a portion of the default area of the electronic device  101 , the extension area, the entire area (e.g., default area +extension area), and/or the virtual area in the virtual space according to the second display mode. 
     If the processing entity related to content is the wearable electronic device  301 , the AR providing device may operate to configure a virtual area corresponding to the extension area of the display module  160  of the electronic device  101  to correspond to the extension area of the electronic device  101 , configure a specified active window (e.g., a window based on the default area or a window based on the entire screen) for the content being displayed on the AR screen through the default area and/or the extension area of the display module  160  of the electronic device  101 , and map and display the content, based on the configured active window. 
     As described above, the AR providing device (e.g., the electronic device  101  or the wearable electronic device  301 ) according to the disclosure may include a processor (e.g., the processor  120  of the electronic device  101  or the processor  590  of the wearable electronic device  301 ). The processor may operate to provide first content (and/or information related to the content) through an AR screen of the wearable electronic device  301 . The processor may operate to detect a specified interaction (e.g., a specified external object (e.g., detect the electronic device  101  entering an AR screen and/or detect a specified gesture)) through the AR screen while providing the content through the AR screen. 
     Based on the detection of the specified interaction, the processor may determine a display mode for second content (e.g., the first content or other content obtained by processing the first content), based on a processing entity providing the second content. 
     Based on the determined display mode (e.g., a first display mode or a second display mode), the processor may operate to display the second content through the display module  160  of the electronic device  101  or map and display the second content to and on a display area associated with a specified external object (e.g., the actual electronic device  101  on the AR screen) on the AR screen through the display module  520  of the wearable electronic device  301 . 
     The second content mapped to the AR screen may be provided only through the display area associated with the electronic device  101  on the AR screen, instead of being displayed through the display module  160  of the electronic device  101  in the real world. 
     If the processing entity related to the content is the wearable electronic device  301 , the processor may operate to monitor a change in state of the electronic device  101  (e.g., interaction for rollable activation) in the AR screen while displaying the content on the AR screen of the wearable electronic device  301 , based on identification of the change in state of the electronic device  101 , determine a display mode of the content, based on the processing entity related to the content, and display the content on an AR screen through the display module  520  of the wearable electronic device  301  or display the content through the display module  160  of the electronic device  101 , based on the determined display mode. 
       FIG.  10    is a flowchart illustrating a method of operating an electronic device or a wearable electronic device according to an embodiment of the disclosure. 
       FIGS.  11 A to  11 F  are diagrams illustrating an example of operation scenarios of an electronic device or a wearable electronic device according to various embodiments of the disclosure. 
     Referring to  FIGS.  10  and  11 A to  11 F , the operations illustrated these figures may be performed by the electronic device  101  or the wearable electronic device  301  depending on the tethered method or the standalone method for providing AR services. Hereinafter, in the description of  FIG.  10   , the electronic device  101  or the wearable electronic device  301  will be referred to as an AR providing device for convenience of description. The electronic device  101  and the wearable electronic device  301  may further include an operation of receiving, processing, and transmitting related data for AR services depending on the entity that performs the operation, and a description thereof will be made with reference to the drawings to be described later. 
     Referring to  FIG.  10   , in operation  1001 , an AR providing device (e.g., the electronic device  101  or the wearable electronic device  301 ) or a processor of the AR providing device (e.g., the processor  120  of the electronic device  101  or the processor  590  of the wearable electronic device  301 ) may provide content through a display module  520  of the wearable electronic device  301 . An example of this is shown in  FIG.  11 A . Referring to  FIG.  11 A , the wearable electronic device  301  may be worn on the user, and the AR providing device may display content (or virtual information)  1110  superimposed on at least a portion of a real space on an AR screen  1100  through the display module  520  of the wearable electronic device  301 . For example, the AR providing device may superimpose content  1110  (e.g., first content  1101 , second content  1102 , and third content  1103 ) in the real space corresponding to the field of view of the user, thereby providing the same to the user. 
     In operation  1003 , the AR providing device may determine whether or not the electronic device  101  is detected in the AR screen. The AR providing device may track whether or not the electronic device  101  enters the real space provided through the display module  520  of the wearable electronic device  301 . An example of this is shown in  FIG.  11 A . Referring to  FIG.  11 A , the user may move the electronic device  101  into the AR screen  1100  provided through the display module  520  of the wearable electronic device  301 . For example, the user may move the electronic device  101  to a corresponding position to be displayed through the AR screen  1100 , and the AR providing device may identify the electronic device  101  moving into the AR screen  1100 , based on tracking of an object and/or gaze on the AR screen  1100 . 
     If the electronic device  101  is not detected in operation  1003  (e.g., “No” in operation  1003 ), the AR providing device may return to operation  1001  and perform operation  1001  and subsequent operations. 
     If the electronic device  101  is detected in operation  1003  (e.g., “Yes” in operation  1003 ), the AR providing device may provide an affordance (or guide) for a virtual area in operation  1005 . If the AR providing device identifies the electronic device  101  on the AR screen and detects a specified interaction (e.g., a rollable activation interaction) for the electronic device  101 , the AR providing device may provide an affordance (or guide) for a virtual area (e.g., the area expected by rollable extension) in response to the specified interaction. An example of this is shown in  FIG.  11 B . Referring to  FIG.  11 B , the AR providing device may provide an affordance  1120 , based on the electronic device  101  or the display module  160  of the electronic device  101 . The AR providing device may provide a virtual window guide corresponding to a default area and/or a substantial extension area of the electronic device  101  as the affordance  1120 . The provision of the affordance  1120  will be described with reference to the drawings below. 
     In operation  1007 , the AR providing device may track whether or not the affordance overlaps content. The user may move the electronic device  101  such that the affordance at least partially overlaps content. The AR providing device may track the electronic device  101  in the AR screen (e.g., track an object) and move the affordance together in response to the movement of the electronic device  101 . An example of this is shown in  FIG.  11 C . Referring to  FIG.  11 C , the affordance  1120  and at least a portion of the content  1110  (e.g., the first content  1101 ) may overlap each other on the AR screen  1100 . 
     If the affordance  1120  and the content  1110  (e.g., the first content  1101 ) overlap, the AR providing device may activate the overlapping content  1110  (e.g., the first content  1101 ) (e.g., move and display the content forward of the affordance  1120 ), thereby distinguishing the overlapping content  1110  (e.g., the first content  1101 ) from the non-overlapping content  1110  (e.g., the second content  1102  and the third content  1103 ). For example, the AR providing device may highlight and provide the overlapping content  1110  (e.g., the first content  1101 ) to be associated with the affordance  1120  so that the user may intuitively recognize the overlapping content  1110 . 
     The electronic device  101  may be a bar-type electronic device in which the display module  160  is not extended and has a fixed size, or may be a rollable type electronic device in which the display module  160  is extendable. For example, the electronic device  101  may include a smartphone, a tablet PC, a notebook computer, and/or a display device (e.g., a monitor or TV) including a display module  160  having a fixed size or a variable size. 
     If the electronic device  101  is a bar-type electronic device, an affordance may be provided based on a display area (e.g., a default area) of the display module  160  of the electronic device  101 , and the affordance and content may be mapped in the display area. If the electronic device  101  is a rollable type electronic device and the display module  160  of the electronic device  101  is in an extended state, an affordance may be provided based on a display area (e.g., default area +extension area) of the display module  160 , and the affordance and content may be mapped in the display area. If the electronic device  101  is a rollable type electronic device and if the display module  160  of the electronic device  101  is in a non-extended state, the display module  160  may provide an affordance, based on an extendable virtual area (e.g., a virtual area having a size corresponding to the extension area), and the affordance and content may be mapped in the virtual area. 
     The content in the AR screen provided through the display module  520  of the wearable electronic device  301  may include space-oriented content that is mapped to the real space and the position of which is adaptively movable according to the user&#39;s gaze or the user&#39;s movement (e.g., head movement) (e.g., the content is moved to always be visible within the user&#39;s gaze, that is, fixedly displayed in a specified area in the display module  520 ). As another example, the content in the AR screen provided through the display module  520  of the wearable electronic device  301  may include device-oriented (or object-oriented) content that is not mapped to the real space but fixedly mapped to a specific space (or an area where a corresponding object is located in the real space) on the AR screen of the display module  520  so as not to be movable according to the user&#39;s gaze or the user&#39;s movement. 
     An operation of mapping (e.g., overlapping) the affordance and the content may vary depending on, for example, whether the content is space-oriented content or device-oriented content. In the case of space-oriented content, the user may overlap content and the affordance by directly moving the electronic device  101  within the AR screen of the display module  520  of the wearable electronic device  301 . In the case of device-oriented content, the user may move the user&#39;s gaze (e.g., move the head) to the display module  160  (e.g., the default area, the extension area, the entire area, or the virtual area) of the electronic device  101  within the AR screen of the display module  520  of the wearable electronic device  301 , and the content may be moved on the AR screen in response to the movement of the user&#39;s gaze so that the content may overlap the affordance in the corresponding area of the electronic device  101 . The movement of content on the AR screen is not limited to the user&#39;s gaze and may be performed, for example, by a user gesture on the AR screen (e.g., a user&#39;s gesture of selecting and moving content on the AR screen). 
     In operation  1009 , the AR providing device may determine whether or not an overlap between the affordance and the content is detected. The AR providing device may determine whether or not the content overlaps the position of the affordance corresponding to the movement of the electronic device  101 . The AR providing device may perform operations  1007  to  1009  for a specified period of time. 
     If no overlap between the affordance and the content is detected in operation  1009  (e.g., “No” in operation  1009 ), the AR providing device may perform a user-specified operation in operation  1011 . If no overlap between the affordance and the content is detected for a specified period of time, the AR providing device may remove the affordance from the AR screen and continue to provide the content. The AR providing device may detect a specified input of the user on the AR screen, remove the affordance in response to the specified input, and perform an operation (or function) (e.g., change the content) corresponding to the specified input. 
     If an overlap between the affordance and the content is detected in operation  1009  (e.g., “Yes” in operation  1009 ), the AR providing device may detect a specified interaction (or an operation trigger) in operation  1013 . If an overlap between the affordance and the content is detected, the AR providing device may determine an interaction of triggering an operation (e.g., an operation trigger) for displaying the corresponding content selected by the overlap with the affordance through a specified target device. An example of this is shown in  FIG.  11 D . 
     Referring to  FIG.  11 D , the user may input a specified interaction  1130  for selecting and determining the first content  1101 , based on an overlap between the affordance  1120  and the first content  1101  on the AR screen  1100 , and displaying the first content  1101  through a target device. The specified interaction may include, for example, a slide-out or rollable extension gesture, an input to a specified hardware button for an extension trigger, or an input to a specified software button for an extension trigger. 
     In operation  1015 , the AR providing device may determine a target device for displaying content, based on detection of the specified interaction. The AR providing device may determine a display mode (e.g., a first display mode or a second display mode) corresponding to a target device for displaying the content selected by the overlap. For example, the AR providing device may determine a display mode and a target device corresponding thereto, based on a content processing entity and/or a specified profile of the content. 
     In operation  1017 , the AR providing device may produce an active window for the content, based on the target device. According to an embodiment of the disclosure, if the target device is the electronic device  101 , the AR providing device may configure an active window for the content, based on the display area of the electronic device  101 . According to another embodiment of the disclosure, if the target device is the wearable electronic device  301 , the AR providing device may configure an active window for the content, based on the display area of the electronic device  101  displayed on the AR screen of the wearable electronic device  301  and/or the virtual area adjacent to the display area. 
     When configuring an active window, the AR providing device may configure the active window in at least one of the default area, the extension area, or the entire area, based on the overlapping state (or overlapping area) of the affordance and the content according to the user&#39;s intention. For example, if the content (e.g., the first content  1101 ) overlaps the affordance, the AR providing device may configure an active window to display the content in the extension area. As another example, if the content (e.g., the first content  1101 ) overlaps both the electronic device  101  (e.g., the default area of the electronic device  101 ) and the affordance on the AR screen, the AR providing device may configure an active window to display the corresponding content in the entire area (e.g., default area +extension area (or virtual area)). As another example, if one piece of content (e.g., the first content  1101 ) is disposed in the affordance, the AR providing device may configure an active window to display the corresponding content in the entire area (e.g., default area+extension area). 
     As another example, if a plurality of content (e.g., the first content  1101  and the second content  1102 ) overlaps the affordance, the AR providing device may configure an active window in each of the default area and the extension area to display the plurality of pieces of content in the default area and the extension area, respectively. As another example, one piece of content (e.g., the first content  1101 ) among a plurality of pieces of content overlaps the affordance and if another piece of content (e.g., the second content  1102 ) thereof overlaps the electronic device  101  (e.g., the default area of the electronic device  101 ), for example, if each piece of content is disposed according to the user&#39;s intention, the AR providing device may configure an active window for the first content  1101  in the extension area and an active window for the second content  1102  in the default area so as to display the content to conform to the disposition according to the user&#39;s intention. For example, in the case of superimposing the second content on a first extension area by a user input, the AR providing device may map the second content to the first extension area of the display module  160  and provide the same. The active window may be divided corresponding to the number of pieces of content to be displayed. 
     As will be described later, the affordance may be variable (e.g., extended) by a user input (e.g., an affordance extension interaction). According to an embodiment of the disclosure, if one piece of content (e.g., the first content  1101 ) is disposed in (e.g., overlaps) the extended affordance, the AR providing device may extend the display module  160  of the electronic device  101  to correspond to the extended affordance and configure an active window so as to display one piece of content on the entire extended screen through the entire area of the extended extension area and the default area. According to another embodiment of the disclosure, if a plurality of pieces of content (e.g., the first content  1101  and the second content  1102 ) is disposed in (e.g., overlaps) the extended affordance, the AR providing device may configure an active window in each of the default area and the extension area so as to display the plurality of pieces of content in the default area and the extension area, respectively, or configure at least one active window in the extension area so as to display the plurality of pieces of content in the extension area corresponding to the extended affordance. 
     In operation  1019 , the AR providing device provide content, based on the active window of the target device. The AR providing device may provide content to correspond to a first display mode or a second display mode through the target device. For example, the AR providing device may display content in a first display mode in which content is provided through an active window (e.g., a real display area of the electronic device  101 ) configure in the electronic device  101 . As another example, the AR providing device may display the content in a second display mode in which content is virtually mapped and provided through an active window configure based on the electronic device  101  in the AR screen of the wearable electronic device  301 . Examples of this are shown in  FIGS.  11 E and  11 F . 
       FIG.  11 E  shows an example of providing content according to the first display mode. Referring to  FIG.  11 E , based on the determination of the first display mode, the AR providing device may perform processing to display the content  1110  selected and determined by the user on the AR screen  1100 , based on a substantial display area (e.g., an extension area extended by sliding-out) corresponding to the display module  160  of the electronic device  101 . If the electronic device  101  performs processing of content or an application corresponding to the content being executed in relation to AR services, the AR providing device may operate to stop displaying the current screen of the wearable electronic device  301  (e.g., turn off the display module  520  or the wearable electronic device  301  in the state in which the wearable electronic device  301  is taken off) and continuously display the first content  1101  selected and determined by the user among the content  1100 , which is being displayed through the AR screen  1100 , through the display module  160  of the electronic device  101  in the real space. 
     The content (e.g., the first content  1101 ) displayed through the display module  160  may be the same as the content (e.g., the first content  1101 ) being displayed on the AR screen  1100  or may be another piece of content obtained by processing (e.g., resizing) the content being displayed on the AR screen  1100  to correspond to the display area of the display module  160 . The content being displayed on the AR screen  1100  and the content to be moved to the electronic device  101  and displayed through the display module  160  may include substantially the same execution screen (or content) and have continuity, and the display size thereof may vary depending on the display area. 
       FIG.  11 F  shows an example of providing content according to the second display mode. Referring to  FIG.  11 F , based on the determination of the second display mode, the AR providing device may perform processing to display the content  1110  based on a virtual area associated with the electronic device  101  on the AR screen  1100  provided through the display module  520  of the wearable electronic device  301 . If the wearable electronic device  301  performs processing of content or an application corresponding to the content being executed in relation to AR services, or if the content to be provided corresponds to a specified profile, the AR providing device may perform the following operations. For example, the AR providing device may operate to map (e.g., texture-map) the first content  1101  selected and determined by the user, among the content  1100  being displayed through the AR screen  1100 , to the default area of the electronic device  101  positioned in the real space displayed on the AR screen  1100  through the display module  520  of the wearable electronic device  301 , the extension area of the electronic device  101 , and/or the virtual area produced adjacent to the electronic device  101  and display the same thereon. 
     For example, the AR providing device may display the first content  1101  selected and determined by the user through the entirety or at least a portion of the default area of the electronic device  101 , the extension area thereof, and/or the virtual area in the AR screen  1100  (e.g., a virtual space) according to the second display mode, and maintain the existing display state of the remaining unselected content (e.g., the second content  1102  and the third content  1103 ) on the AR screen  1100 . 
     The content (e.g., the first content  1101 ) displayed in a specified area through mapping may be the same as the content (e.g., the first content  1101 ) being displayed on the AR screen  1100  or may be another piece of content obtained by processing (e.g., resizing) the content being displayed on the AR screen  1100  to correspond to the specified area. The content being displayed on the AR screen  1100  and the content displayed through mapping may include substantially the same execution screen (or content) and have continuity, and the display size thereof may vary depending on the display area. 
     An element  1190  may show an example of a display state of the display module  160  of the electronic device  101  viewed in the real space, instead of the electronic device  101  on the AR screen  1100  provided through the display module  520  of the wearable electronic device  301 . As illustrated, the electronic device  101  may maintain a screen display being executed (or operated) in the electronic device  101 , as shown in  FIG.  11 A , through a default area and provide a blank screen or a specified screen to an extension area  1195  corresponding to extension of the display module  160  (e.g., an area extended by sliding-out). 
     For example, the electronic device  101  may provide, as a specified screen, a screen resulting from execution of a specified function in response to extension of the display module  160  (e.g., a split screen based on execution of a specified application or the entire screen of a running application (e.g., display the screen displayed in the default area into a full screen)). The display module  160  of the electronic device  101  in the real space may be in the state of being turned off. 
     For example, in the second display mode, the screen (e.g., the display screen of the first content  1101 ) displayed based on the display module  160  of the electronic device  101  on the AR screen  1100  and the screen displayed through the display module  160  of the electronic device  101  in the real space may be different, and the display module  160  of the electronic device  101  may not display the content (e.g., the first content  1101 ) on the AR screen  1200  in the real space. 
       FIGS.  12 A to  12 F  are diagrams illustrating an example of operation scenarios of an electronic device or a wearable electronic device according to various embodiments of the disclosure. 
       FIGS.  12 A to  12 F  show examples of changing a display area for providing content according to a user input, in addition to the operation described with reference to  FIGS.  10 , and  11 A to  11 F . 
     Referring to  FIG.  12 A , an AR providing device (e.g., an electronic device  101  or a wearable electronic device  301 ) may provide content (e.g., first content  1201 , second content  1202 , and third content  1203 ) to an AR screen  1200  through the display module  520  of the wearable electronic device  301 . The wearable electronic device  301  may be worn on the user, and the AR providing device may display a portion of content (or virtual information) superimposed on at least a portion of a real space on the AR screen  1200  through the display module  520  of the wearable electronic device  301 . For example, the AR providing device may superimpose at least one piece of content (e.g., first content  1201 , second content  1202 , and third content  1203 ) in the real space corresponding to the field of view of the user, thereby providing the content to the user. 
     In the above situation, the user may move an electronic device  101  into the AR screen  1200  provided through the display module  520  of the wearable electronic device  301 . If the AR providing device detects a user&#39;s specified interaction (e.g., a rollable activation interaction) for the electronic device  101  on the AR screen  1200 , the AR providing device may provide an affordance (or guide)  1220  for a virtual area (e.g., the area expected by rollable extension) in response to the specified interaction. The specified interaction may include, for example, a slide-out or rollable extension gesture, an input to a specified hardware button for an extension trigger, or an input to a specified software button for an extension trigger. The AR providing device may provide a virtual window guide corresponding to a default area and/or a substantial extension area of the electronic device  101  as the affordance  1220 . The provision of the affordance  1220  according to an embodiment will be described with reference to the drawings to be described later. 
     The user may move the electronic device  101  such that the affordance  1220  at least partially overlaps the first content  1201  on the AR screen  1200 . The AR providing device may track the electronic device  101  in the AR screen  1200  (e.g., track an object) and move the affordance  1220  together in response to the movement of the electronic device  101 . In response to the movement of the electronic device  101  by the user, the affordance  1220  and the first content  1201  may overlap each other on the AR screen  1200 . If the affordance  1220  and the first content  1201  overlap each other, the AR providing device may activate the overlapping first content  1201  (e.g., move and display the content forward of the affordance  1220 ), thereby providing the overlapping first content  1201  and the remaining non-overlapping content (e.g., the second content  1202  and the third content  1203 ) to be distinguished. For example, the AR providing device may highlight and provide the overlapping first content  1201  to be associated with the affordance  1220  so that the user may intuitively recognize the overlapping first content  1201 . 
     The electronic device  101  may be a bar-type electronic device in which the display module  160  is not extended and has a fixed size, or may be a rollable type electronic device in which the display module  160  is extendable. For example, the electronic device  101  may include a smartphone, a tablet PC, a notebook computer, and/or a display device (e.g., a monitor or TV) including a display module  160  having a fixed size or a variable size. 
     According to an embodiment of the disclosure, if the electronic device  101  is a bar-type electronic device, an affordance may be provided based on a display area (e.g., a default area) of the display module  160  of the electronic device  101 , and the affordance and content may be mapped in the display area. 
     According to another embodiment of the disclosure, if the electronic device  101  is a rollable type electronic device and if the display module  160  of the electronic device  101  is in an extended state, an affordance may be provided based on a display area (e.g., default area +extension area) of the display module  160 , and the affordance and content may be mapped in the display area. 
     If the electronic device  101  is a rollable type electronic device and if the display module  160  of the electronic device  101  is in a non-extended state, the display module  160  may provide an affordance, based on an extendable virtual area (e.g., a virtual area having a size corresponding to the extension area), and the affordance and content may be mapped in the virtual area. 
     The content in the AR screen provided through the display module  520  of the wearable electronic device  301  may include space-oriented content that is mapped to the real space and the position of which is adaptively movable according to the user&#39;s gaze or the user&#39;s movement (e.g., head movement) (e.g., the content is moved to always be visible within the user&#39;s gaze, that is, fixedly displayed in a specified area in the display module  520 ). As another example, the content in the AR screen provided through the display module  520  of the wearable electronic device  301  may include device-oriented (or object-oriented) content that is not mapped to the real space but fixedly mapped to a specific space (or an area where a corresponding object is located in the real space) on the AR screen of the display module  520  so as not to be movable according to the user&#39;s gaze or the user&#39;s movement. 
     An operation of mapping (e.g., overlapping) the affordance and the content may vary depending on, for example, whether the content is space-oriented content or device-oriented content. For example, in the case of space-oriented content, the user may overlap content and the affordance by directly moving the electronic device  101  within the AR screen of the display module  520  of the wearable electronic device  301 . As another example, in the case of device-oriented content, the user may move the user&#39;s gaze (e.g., move the head) to the display module  160  (e.g., the default area, the extension area, the entire area, or the virtual area) of the electronic device  101  within the AR screen of the display module  520  of the wearable electronic device  301 , and the content may be moved on the AR screen in response to the movement of the user&#39;s gaze so that the content may overlap the affordance in the corresponding area of the electronic device  101 . 
     The movement of content on the AR screen is not limited to the user&#39;s gaze and may be performed, for example, by a user gesture on the AR screen (e.g., a user&#39;s gesture of selecting and moving content on the AR screen). In addition to the selection by overlapping of the first content  1201 , the user may input a first interaction  1230  (e.g., an affordance extension interaction) for varying (e.g., extending) the affordance  1220  in order to further select another piece of content (e.g., the second content  1202 ) by overlapping of the affordance  1220 . In an embodiment, the AR providing device may extend the affordance  1220  in response to the first interaction and provide the same. An example of this is shown in  FIG.  12 B . 
     Although it is described that the affordance  1220  is extended (e.g., varied) based on the user&#39;s interaction, this example is intended only to help the understanding of the disclosure and is not intended to limit embodiments of the disclosure. For example, the affordance  1220 , is not limited to the variation based on the user&#39;s interaction, and may automatically vary. For example, if the size of the extension area by the affordance  1220  is not suitable for displaying content (e.g., excessively larger or smaller than the displayable size of the content,) in displaying the content overlapping the affordance  1220 , the AR providing device may calculate the size of the extension area capable of displaying the overlapping content and vary (e.g., extend) the affordance  1220  to conform to the size of the calculated extension area, thereby providing the same. 
     Referring to  FIG.  12 B , the AR providing device may vary (e.g., extend) the affordance  1220  to conform to the variable size (or movement distance) of the first interaction and provide the same to the AR screen  1200 . As shown in  FIG.  12 B , as the affordance  1220  is extended, another piece of content (e.g., the second content  1202 ), as well as the first content  1201 , may overlap the affordance  1220 . If the affordance  1220  and the second content  1202  overlap in addition to the first content  1201 , the AR providing device may further activate the overlapping second content  1202  (e.g., move and display the content forward of the affordance  1220 ), thereby providing the overlapping first content  1201  and second content  1202  to be distinguished from the remaining non-overlapping content (e.g., the third content  1203 ). For example, the AR providing device may highlight and provide the overlapping first content  1201  and second content  1202  to be associated with the affordance  1220  so that the user may intuitively recognize the overlapping first content  1201  and second content  1202 . 
     Referring to  FIG.  12 C , the user may move the electronic device  101  in order to further select another piece of content (e.g., the third content  1203 ) in addition to the selection by the overlapping of the first content  1201  and second content  1202 . According to an embodiment, in order to select all of the content (e.g., the first content  1201 , the second content  1202 , and the third content  1203 ) disposed side by side on the AR screen  1200 , the user may move the electronic device  101  such that the affordance  1220  at least partially overlaps the third content  1203  on the AR screen  1200 . 
     Referring to the example in  FIG.  12 C , the electronic device  101  may move in the right direction, and the affordance  1220  may also move in response to the movement of the electronic device  101 . The first content  1201 , the second content  1202 , and the third content  1203  may be fixed to be displayed without changing their positions. An overlapping portion of the first content  1201 , the second content  1203 , and the third content  1205  may vary in response to the movement of the electronic device  101 . For example, the first content  1201  may be positioned on the display module  160  of the electronic device  101 , the second content  1202  may be positioned in the area where the first content  1201  was positioned in the affordance  1220  by replacing the same, and the third content  1203  may be further positioned in the area where the second content  1202  was positioned in the affordance  1220 . 
     Referring to  FIG.  12 D , the AR providing device may detect a second interaction  1240  of triggering an operation (e.g., an operation trigger) of displaying at least one piece of content (e.g., the first content  1201 , the second content  1202 , or the third content  1203 ) selected by the user through a specified target device. For example, the user may select and determine the first content  1201 , the second content  1202 , and the third content  1203  on the AR screen  1200  and input a specified second interaction  1240  (e.g., a rollable extension gesture, another specified touch gesture, or a voice-based command) for displaying the selected first content  1201 , second content  1202 , and third content  1203  through the target device. 
     The AR providing device may determine a target device for displaying content, based on the detection of the second interaction  1240 . The AR providing device may determine a display mode (e.g., a first display mode or a second display mode) corresponding to a target device for displaying the content selected by the user. For example, the AR providing device may determine a display mode and a target device corresponding thereto, based on a content processing entity and/or a specified profile of the content. 
     The AR providing device may provide content through the target device to conform to the first display mode or the second display mode. For example, the AR providing device may display content in a first display mode in which content is provided through a real display area based on the display module  160  of the electronic device  101 . As another example, the AR providing device may display content in a second display mode in which content is mapped and provided through a virtual display area configure based on the electronic device  101  in the AR screen  1200  of the wearable electronic device  301 . Examples of this are shown in  FIGS.  12 E and  12 F . 
       FIG.  12 E  shows an example of providing content according to the first display mode. 
     Referring to  FIG.  12 E , based on the determination of the first display mode, the AR providing device may perform processing to display the content (e.g., the first content  1201 , the second content  1202 , and the third content  1203 ) selected and determined by the user on the AR screen  1200 , based on a substantial display area (e.g., a default area and an extension area that is extended by sliding-out) corresponding to the display module  160  of the electronic device  101 . 
     If the electronic device  101  performs processing of content or an application corresponding to the content being executed in relation to AR services, the AR providing device may operate to stop displaying the current screen of the wearable electronic device  301  (e.g., turn off the display module  520  or the wearable electronic device  301  in the state in which the wearable electronic device  301  is taken off) and continuously display the first content  1201 , the second content  1202 , and the third content  1203  selected and determined by the user on the AR screen through the display module  160  of the electronic device  101  in the real space. 
     The AR providing device may display the content on the display module  160  to conform to the position where each piece of content  1201 ,  1202 , or  1203  overlaps the electronic device  101  on the AR screen  1200 . For example, the first content  1201  may overlap the default area of the electronic device  101  on the AR screen  1200 , and the first content  1201  may be provided through the default area of the display module  160  of the electronic device  101  in the real space. For example, the second content  1202  may overlap the first extension area of the electronic device  101  on the AR screen  1200 , and the second content  1202  may be provided through the first extension area of the display module  160  of the electronic device  101  in the real space. For example, the third content  1203  may overlap the second extension area of the electronic device  101  on the AR screen  1200 , and the third content  1203  may be provided through the second extension area of the display module  160  of the electronic device  101  in the real space. 
       FIG.  12 F  shows an example of providing content according to the second display mode. 
     Referring to  FIG.  12 F , based on the determination of the second display mode, the AR providing device may perform processing to display the content (e.g., the first content  1201 , the second content  1202 , and the third content  1203 ), based on a virtual area associated with the electronic device  101  on the AR screen  1200  provided through the display module  520  of the wearable electronic device  301 . 
     If the wearable electronic device  301  performs processing of content or an application corresponding to the content being executed in relation to the AR service, or if the content to be provided corresponds to a specified profile, the AR providing device may perform the following operations. For example, the AR providing device may operate to map (e.g., texture-map) the first content  1201 , the second content  1202 , and the third content  1203  selected and determined by the user from the AR screen  1200  to the default area of the electronic device  101  positioned in the real space displayed on the AR screen  1200  through the display module  520  of the wearable electronic device  301 , the extension area of the electronic device  101 , and/or the virtual area produced adjacent to the electronic device  101  and display the same thereon. The AR providing device may display the first content  1201 , the second content  1202 , and the third content  1203  selected and determined by the user through the entirety or at least a portion of the default area of the electronic device  101 , the extension area thereof, and/or the virtual area in the AR screen  1200  (e.g., a virtual space) according to the second display mode. 
     An element  1290  may show an example of a display state of the display module  160  of the electronic device  101  viewed in the real space, instead of the electronic device  101  on the AR screen  1200  provided through the display module  520  of the wearable electronic device  301 . As illustrated, the electronic device  101  may maintain a screen display being executed (or operated) in the electronic device  101 , as shown in  FIG.  12 A , through a default area and provide a blank screen or a specified screen to an extension area  1295  corresponding to extension of the display module  160  (e.g., an area extended by sliding-out). For example, the electronic device  101  may provide, as a specified screen, a screen resulting from execution of a specified function in response to extension of the display module  160  (e.g., a split screen based on execution of a specified application or the entire screen of a running application (e.g., display the screen displayed in the default area into a full screen)). According to an embodiment, the display module  160  of the electronic device  101  in the real space may be in the state of being turned off. 
     In the second display mode, the screen (e.g., the display screen of the first content  1201 , the second content  1202 , and the third content  1203 ) displayed based on the display module  160  of the electronic device  101  on the AR screen  1200  and the screen displayed through the display module  160  of the electronic device  101  in the real space may be different, and the display module  160  of the electronic device  101  may not display the content (e.g., the first content  1201 , the second content  1202 , and the third content  1203 ) on the AR screen  1200  in the real space. 
     The AR providing device may dispose and display the content to correspond to the position where each piece of content  1201 ,  1202 , or  1203  overlaps the electronic device  101  on the AR screen  1200 . For example, the first content  1201  may overlap the default area of the electronic device  101  on the AR screen  1200 , and the first content  1201  may be mapped and provided to the default area of the display module  160  of the electronic device  101 . The second content  1202  may overlap the first extension area (or first virtual area) of the electronic device  101  on the AR screen  1200 , and the second content  1202  may be mapped and provided to the first extension area (or first virtual area) of the display module  160  of the electronic device  101 . The third content  1203  may overlap the second extension area (or second virtual area) of the electronic device  101  on the AR screen  1200 , and the third content  1203  may be mapped and provided to the second extension area (or second virtual area) of the display module  160  of the electronic device  101 . 
       FIGS.  13 A to  13 C  are diagrams illustrating an example of configuring an active window in association with an electronic device provided through an AR screen according to various embodiments of the disclosure. 
       FIGS.  13 A,  13 B, and  13 C  show various examples of providing an affordance for an expected screen in which the content selected by the user on an AR screen  1300  is to be displayed according to a first display mode or a second display mode to the AR screen  1300 . An active window may be configured to correspond to a given affordance in the first display mode or the second display mode. For example, according to the disclosure, it is possible to guide the user in advance about an expected screen in which the content selected by the user on the AR screen  1300  is to be displayed in a corresponding display mode using affordance. 
     Referring to  FIG.  13 A , an affordance  1310  for an active window may be provided to a virtual area V while a default area A of the electronic device  101  is maintained. The virtual area V may be produced according to the size (or ratio) corresponding to the default area A or may be produced according to the size (or ratio) corresponding to the extendable extension area of the electronic device  101 . If the size of the extension area by the affordance  1310  is not suitable for displaying content (e.g., excessively larger or smaller than the displayable size of the content,) in displaying the content, the AR providing device may calculate the size of the extension area capable of displaying the overlapping content and vary (e.g., extend) the affordance  1310  to conform to the size of the calculated extension area so as to provide the content. Accordingly, the virtual area V may vary depending on the size (or ratio) of the variable affordance  1310 . 
     Referring to  FIG.  13 B , since a user interaction (e.g., a rollable activation gesture) reflects a clear intention of the user for screen extension of the electronic device  101 , an affordance  1320  for an active window may be provided to the entire area including the default area A of the electronic device  101  and the virtual area V. For example, the entire area (e.g., default area +extension area) including the default area and the extension area of the display module  160  of the electronic device  101  may be configured as an active window for displaying content. 
     Referring to  FIG.  13 C , in  FIG.  13 C , an affordance  1330  for an active window may be provided based on an extension area E in which the electronic device  101  is substantially extended on the AR screen  1300 . For example, if the display module  160  of the electronic device  101  is substantially extended, the extension area E may be configured as an active window for displaying content. 
     Referring to  FIGS.  13 A to  13 C , affordances  1310 ,  1320 , and  1330  may be varied (e.g., extended) by a user input (e.g., an affordance extension interaction). According to an embodiment of the disclosure, if one piece of content (e.g., first content) is disposed in (e.g., overlaps) the extended affordance, the AR providing device may extend the display module  160  of the electronic device  101  to correspond to the extended affordance and configure an active window so as to display one piece of content on the entire extended screen through the entire area of the extended extension area and the default area. According to another embodiment of the disclosure, if a plurality of pieces of content (e.g., first content and second content) is disposed in (e.g., overlaps) the extended affordance, the AR providing device may configure an active window in each of the default area and the extension area so as to display the plurality of pieces of content in the default area and the extension area, respectively, or configure at least one active window in the extension area so as to display the plurality of pieces of content in the extension area corresponding to the extended affordance. 
     When configuring an active window, the AR providing device may configure the active window in at least one of the default area, the extension area, or the entire area, based on the overlapping state (or overlapping area) of the affordance and the content according to the user&#39;s intention. 
     For example, if the content overlaps the affordance, the AR providing device may configure an active window to display the content in the extension area. As another example, if the content overlaps both the electronic device  101  (e.g., the default area of the electronic device  101 ) and the affordance on the AR screen, the AR providing device may configure an active window to display the corresponding content in the entire area (e.g., default area+extension area (or virtual area)). As another example, if a plurality of pieces of content (e.g., first content and second content) overlaps the affordance, the AR providing device may configure an active window in each of the default area and the extension area to display the plurality of pieces of content in the default area and the extension area, respectively. 
     As another example, if one piece of content (e.g., first content) among a plurality of pieces of content overlaps the affordance and another piece of content (e.g., second content) thereof overlaps the electronic device  101  (e.g., the default area of the electronic device  101 ), for example, if each piece of content is disposed according to the user&#39;s intention (e.g., a user input of selecting and moving content to a certain area), the AR providing device may configure an active window for the first content in the extension area and an active window for the second content in the default area so as to display the content to conform to the disposition according to the user&#39;s intention. In the case of superimposing the second content on a first extension area by a user input, the AR providing device may map the second content to the first extension area of the display module  160  and provide the second content. The active window may be divided corresponding to the amount of content to be displayed. 
       FIGS.  14 A to  14 F  are diagrams illustrating an example of operation scenarios of an electronic device or a wearable electronic device according to various embodiments of the disclosure. 
     Referring to  FIGS.  14 A to  14 F , the illustrated operations may be performed by the wearable electronic device  301  according to the standalone method of providing an AR service. For example,  FIGS.  14 A to  14 F  show examples in which the electronic device  101  is unable to process content or an application corresponding to the content being executed in relation to an AR service.  FIGS.  14 A to  14 F  show examples of mapping and displaying content displayed on an AR screen provided through the display module  520  of the wearable electronic device  301  on the AR screen in association with the electronic device  101  and processing a user input for the content displayed to be mapped to the electronic device  101 .  FIGS.  14 A to  14 F  include an example of manipulating content being executed through the wearable electronic device  301  in the standalone method using the electronic device  101  after the display module  160  of the electronic device  101  is extended (e.g., slides out). In  FIGS.  14 A to  14 F , content is implemented (or used) by the wearable electronic device  301  in the standalone method and may be, for example, content that is unable to be processed by the electronic device  101 . 
     Referring to  FIG.  14 A , the wearable electronic device  301  may provide content  1410  to an AR screen  1400  through the display module  520  of the wearable electronic device  301 . The wearable electronic device  301  may be worn on the user, and at least one piece of content (or virtual information) superimposed on at least a portion of a real space may be displayed on the AR screen  1400  through the display module  520  of the wearable electronic device  301 . For example, the wearable electronic device  301  may superimpose at least one piece of content  1410  in the real space corresponding to the field of view of the user, thereby providing the same to the user. 
     Referring to  FIG.  14 B , in the above situation, the user may move the electronic device  101  into the AR screen  1400  provided through the display module  520  of the wearable electronic device  301 . 
     Referring to  FIG.  14 C , if the wearable electronic device  301  detects a user&#39;s specified interaction (e.g., a rollable activation interaction) for the electronic device  101  on the AR screen  1400 , the wearable electronic device  301  may provide an affordance (or guide)  1420  for a virtual area (e.g., the area expected by rollable extension or the area calculated to conform to the size of the content  1410 ) in response to the specified interaction. The wearable electronic device  301  may provide a virtual window guide corresponding to a default area and/or a substantial extension area of the electronic device  101  as the affordance  1420 . 
     The user may move the electronic device  101  such that the affordance  1420  overlaps the content  1410  on the AR screen  1400 . According to an embodiment, the wearable electronic device  301  may track the electronic device  101  in the AR screen  1400  (e.g., track an object), and the affordance  1420  may also move in response to the movement of the electronic device  101 . In response to the movement of the electronic device  101  by the user, the affordance  1420  and the content  1410  may overlap each other on the AR screen  1400 . If the affordance  1420  and the content  1410  overlap, the wearable electronic device  301  may activate the overlapping content  1401  (e.g., move and display the content forward of the affordance  1420 ), thereby providing the overlapping content  1401  to be distinguished. For example, the wearable electronic device  301  may highlight and provide the overlapping content  1410  to be associated with the affordance  1420  so that the user may intuitively recognize the overlapping (or user-selected) content  1410 . 
     The wearable electronic device  301  may vary (e.g., extend) the affordance  1420 , based on the variable size (or movement distance) corresponding to an additional interaction by the user, and provide the same to the AR screen  1400 . For example, the user may further extend the affordance  1420  such that all of the content  1410  on the AR screen  1400  is to be included in the affordance  1420 , so that the content  1410  may overlap the affordance  1420  according to the additional extension of the affordance  1420 . 
     The AR providing device may determine the size of the affordance  1420  capable of displaying the content  1410 , based on the size of the content  1410 , and the additional extension of the affordance  1420  may be automatically performed according to the determined size. For example, if the size of the extension area by the affordance  1420  is not suitable for displaying content (e.g., excessively larger or smaller than the displayable size of the content,) in displaying the content, the size of the extension area capable of displaying the overlapping content  1410  may be calculated, and the affordance  1420  may be varied (e.g., extended) to conform to the size of the calculated extension area and then provided. Accordingly, the extension area V of the electronic device  101  may vary according to the size (or ratio) of the variable affordance  1420 . 
     Referring to  FIG.  14 D , the wearable electronic device  301  may detect an interaction  1430  of triggering an operation (e.g., an operation trigger) for displaying the content  1410  selected by the user through a specified target device. For example, the user may select and determine the content  1401  from the AR screen  1400  and input a specified interaction  1430  (e.g., a rollable extension gesture, another specified touch gesture, or a voice-based command) for displaying the selected content  1410  through the target device. 
     The wearable electronic device  301  may determine a target device for displaying the content  1410 , based on the detection of the interaction  1430 . The AR providing device may determine a display mode (e.g., a first display mode or a second display mode) corresponding to a target device for displaying the content  1410  selected by the user. For example, the wearable electronic device  301  may determine a display mode and a target device corresponding thereto, based on a processing entity of the content  1410  and/or a specified profile of the content  1410 . 
     The wearable electronic device  301  may provide content to correspond to the first display mode or the second display mode through the target device. For example, the wearable electronic device  301  may display the content  1410  in a first display mode in which content is provided through a real display area based on the display module  160  of the electronic device  101 . The content  1410  may include content implemented (or used) by the wearable electronic device  301  in the standalone method. For example, the content  1410  may indicate content that is unable to be processed by the electronic device  101 . Therefore, when providing the content  1410  in the first display mode, the wearable electronic device  301  may operate to mirror and provide the content  1410  to the electronic device  101 . As another example, the wearable electronic device  301  may display the content  1410  in a second display mode in which content is mapped and provided through a virtual display area configure based on the electronic device  101  in the AR screen  1400  of the wearable electronic device  301 . Examples of this are shown in  FIGS.  14 E and  14 F . 
       FIG.  14 E  shows an example of providing content of the wearable electronic device  301  through the electronic device  101  according to the first display mode. Referring to  FIG.  14 E , based on the determination of the first display mode, the wearable electronic device  301  may perform processing to display the content  1410  selected and determined by the user on the AR screen  1400 , based on a substantial display area (e.g., a default area and an extension area that is extended by sliding-out) corresponding to the display module  160  of the electronic device  101 . 
     If the wearable electronic device  301  processes content or an application corresponding to the content is being executed in relation to AR services, the wearable electronic device  301  may operate to mirror and transmit the content  1410  selected by the user from the AR screen  1400  to the electronic device  101  and continuously display the content through the display module  160  of the electronic device  101  in the real space. For example, the wearable electronic device  301  may perform processing of content or an application corresponding to the content being executed in relation to AR services, and the electronic device  101  may receive (e.g., mirroring) the content  1410  selected and determined by the user on the wearable AR screen  1400  from the wearable electronic device  301  through specified communication and display the mirrored content  1410  through the display module  160  of the electronic device  101 . 
     The wearable electronic device  301  may transmit the content  1410  of the display module  520  that is being processed to the electronic device  101  so as to be displayed on the display module  160  of the electronic device  101 . For example, a transmission entity and a processing entity of the content  1410  may be the wearable electronic device  301 . According to an embodiment, the electronic device  101  may serve to display the content  1410  or related information transmitted from the wearable electronic device  301 . 
     The electronic device  101  may extend the display module  160  to correspond to the size of the content  1410  being processed on the AR screen  1400  of the wearable electronic device  301  or the size of the affordance  1420  and display the content  1410  received from the wearable electronic device  301 , based on the default area and the extension area. For example, the content  1410  may overlap the affordance  1420  having a further extended size on the AR screen  1400 , and in the real space, the display module  160  of the electronic device  101  may be extended (slides out) to correspond to the size of the affordance  1420  so that the content  1410  may be provided through the default area and the extension area or through the extension area having a corresponding size, excluding the default area. The size of the extension area of the electronic device  101  may be determined based on a predetermined ratio specified by the user through the affordance  1420  on the AR screen  1400 . 
     The electronic device  101  may operate to detect a user input (or interaction)  1440  for controlling a function related to the content  1410  displayed through the display module  160  and process a function corresponding to the user input  1440 . The electronic device  101  may recognize a point (e.g., a touch point) at which the user input  1440  is detected in the content  1410  and transmit related information about the detected point (e.g., coordinates and/or spatial information) to the wearable electronic device  303  such that the wearable electronic device  301  processes a function related to the related information. 
     The wearable electronic device  301  may recognize the point (e.g., a touch point) at which the user input  1440  is detected in the electronic device  101 , based on the related information received from the electronic device  101 , perform processing to execute a related function based on the recognition result, and transmit content data resulting from the processing to the electronic device  101 . The electronic device  101  may receive the processing result (e.g., content data) from the wearable electronic device  301 , reflect the received processing result on the content  1410  on the display module  160 , and display a result screen thereof through the display module  160 . 
     An example of manipulating the content being executed through the wearable electronic device  301  in the standalone method using the electronic device  101  after the display module  160  of the electronic device  101  is extended (e.g., slides out) will be described with reference to the drawings to be described later. 
       FIG.  14 F  shows an example of providing content according to the second display mode. 
     Referring to  FIG.  14 F , based on the determination of the second display mode, the wearable electronic device  301  may perform processing to display the content  1410 , based on a virtual area associated with the electronic device  101 , on the AR screen  1400  provided through the display module  520  of the wearable electronic device  301 . If the wearable electronic device  301  processes content or an application corresponding to the content is being executed in relation to AR services, or if the content to be provided corresponds to a specified profile, the wearable electronic device  301  may perform the following operations. The wearable electronic device  301  may operate to map (e.g., texture-map) the content  1410  selected and determined by the user on the AR screen  1400  to the default area of the electronic device  101  positioned in the real space displayed on the AR screen  1400  through the display module  520  of the wearable electronic device  301 , the extension area of the electronic device  101 , and/or the virtual area produced adjacent to the electronic device  101  and display the same thereon. The wearable electronic device  301  may display the content  1410  selected and determined by the user through the entirety or at least a portion of the default area of the electronic device  101 , the extension area thereof, and/or the virtual area in the AR screen  1400  (e.g., a virtual space) according to the second display mode. 
     The wearable electronic device  301  may disposed and display the content  1410  in a virtual area having a size corresponding to the affordance  1420  associated with the electronic device  101  on the AR screen  1400 . For example, the content  1410  may overlap a virtual area corresponding to the affordance  1420  in the AR screen  1400 , and the AR providing device may produce an active window (e.g., a virtual area) having a corresponding size based on the affordance  1420  and map the content  1410  to the active window, thereby providing the same. 
     Sn element  1490  may show an example of a display state of the display module  160  of the electronic device  101  viewed in the real space, instead of the electronic device  101  on the AR screen  1400  provided through the display module  520  of the wearable electronic device  301 . As illustrated, the electronic device  101  may display a screen being executed (or operated) in the electronic device  101  shown in  FIG.  14 A  through a default area or the entire area or maintain the display in the default area and provide a blank screen or a specified screen to an extension area  1495  corresponding to extension of the display module  160  (e.g., an area extended by sliding-out). For example, the electronic device  101  may provide, as a specified screen, a screen resulting from execution of a specified function in response to extension of the display module  160  (e.g., a split screen based on execution of a specified application or the entire screen of a running application (e.g., display the screen displayed in the default area into a full screen)). According to an embodiment, the display module  160  of the electronic device  101  in the real space may be in the state of being turned off. 
     For example, in the second display mode, the screen (e.g., the display screen of the first content  1410 ) displayed based on the display module  160  of the electronic device  101  on the AR screen  1400  and the screen displayed through the display module  160  of the electronic device  101  in the real space may be different, and the display module  160  of the electronic device  101  may not display the content (e.g., the first content  1410 ) on the AR screen  1400  in the real space. 
     The wearable electronic device  301  may operate to track and detect a user input (or interaction)  1450  for controlling a function related to the content  1410  on the AR screen  1400  and process a function corresponding to the user input  1450 . When displaying the content  1410  based on the second display mode, the wearable electronic device  301  in the standalone method may perform processing to track and detect the user input  1450 , based on technologies such as gaze tracking and object detection, calculate a point (e.g., a touch point) where the user input  1450  is detected in the content  1410 , and execute a related function. 
     The wearable electronic device  301  may detect a user input (or interaction) for the content  1410  on the AR screen  1400 , and the processing of the user input may be performed in the wearable electronic device  301 . The wearable electronic device  301  may receive information related to a user input from the electronic device  101  and cause the electronic device  101  to process a user input made by the electronic device  101 . 
       FIGS.  15 A to  15 F  are diagrams illustrating an example of operation scenarios of an electronic device or a wearable electronic device according to various embodiments of the disclosure. 
     Referring to  FIGS.  15 A to  15 F , the illustrated operations may be performed by the electronic device  101  or the wearable electronic device  301  depending on the tethered method or the standalone method for providing an AR service. The electronic device  101  or the wearable electronic device  301  will be referred to as an AR providing device for convenience of description. 
       FIGS.  15 A to  15 F  show examples in which the content (e.g., protected content or privacy content) according to a specified profile or user setting (e.g., protection configuration by the user), among the content displayed in an AR screen provided through the display module  520  of the wearable electronic device  301 , is not displayed on the display module  160  of the electronic device  101  in the real space. Referring to  FIG.  15 A , the AR providing device (e.g., the electronic device  101  or the wearable electronic device  301 ) may provide content (e.g., first content  1510  and second content  1520 ) to an AR screen  1500  through the display module  520  of the wearable electronic device  301 . The wearable electronic device  301  may be worn on the user, and the AR providing device may display at least one piece of content (or virtual information) superimposed on at least a portion of a real space on an AR screen  1500  through the display module  520  of the wearable electronic device  301 . For example, the AR providing device may superimpose at least one piece of content (e.g., first content  1510  and second content  1520 ) in the real space corresponding to the field of view of the user, thereby providing the content to the user. 
     In the above situation, the user may move the electronic device  101  into the AR screen  1500  provided through the display module  520  of the wearable electronic device  301 . If the AR providing device detects a specified interaction (e.g., a rollable activation interaction) for the electronic device  101  on the AR screen  1500 , the AR providing device may provide an affordance (or guide)  1530  for a virtual area (e.g., the area expected by rollable extension) in response to the specified interaction. The AR providing device may provide a virtual window guide corresponding to a default area and/or a substantial extension area of the electronic device  101  as the affordance  1530 . 
     The user may move the electronic device  101  such that the affordance  1530  at least partially overlaps the first content  1510  on the AR screen  1500 . The AR providing device may track the electronic device  101  in the AR screen  1500  (e.g., track an object) and move the affordance  1530  together in response to the movement of the electronic device  101 . In response to the movement of the electronic device  101  by the user, the affordance  1530  and the first content  1510  may overlap each other on the AR screen  1500 . If the affordance  1530  and the first content  1510  overlap each other, the AR providing device may activate the overlapping first content  1510  (e.g., move and display the content forward of the affordance  1530 ), thereby providing the overlapping first content  1510  and the remaining non-overlapping content (e.g., the second content  1520 ) to be distinguished. For example, the AR providing device may highlight and provide the overlapping first content  1510  to be associated with the affordance  1530  so that the user may intuitively recognize the overlapping first content  1510 . 
     In addition to the selection by overlapping of the first content  1510 , the user may vary (e.g., extend) the affordance  1530  in order to select another piece of content (e.g., the second content  1520 ) by overlapping of the affordance  1530 . The AR providing device may extend the affordance  1530  in response to a user input and provide the affordance  1530 . An example of this is shown in  FIG.  15 B . 
     Referring to  FIG.  15 B , the AR providing device may vary (e.g., extend) the affordance  1530  and provide the affordance  1530  to the AR screen  1500 . As shown in  FIG.  15 B , as the affordance  1530  is extended, the first content  1510  and the second content  1520  may overlap the affordance  1530 . If the affordance  1530  and the second content  1520  overlap in addition to the first content  1510 , the AR providing device may further activate the overlapping second content  1520  (e.g., move and display the content forward of the affordance  1530 ), thereby highlighting the first content  1510  and second content  1520  to be associated with the affordance  1530  and providing the first content  1510  and the second content  1520 . 
     In the above situation, the user may configure at least one piece of content to be protected (or hidden). For example, as shown in  FIG.  15 B , the user may input a first interaction  1540  (e.g., a protection configuration interaction) in association with the second content  1520  to configure the second content  1520  to be protected. The first interaction  1540  on the content of the AR screen  1500  may include a specified touch gesture (e.g., a long-press gesture) for protection of specified content, an interaction of calling and selecting a menu for protection of specified content, or a voice-based command capable of instructing protection of specified content. The protected (or hidden) content may be released from the protection, based at least on an input corresponding to the interaction for protecting the content or another interaction specified to release the protection. 
     The AR providing device may detect a first interaction  1540  and, based on the detection of the first interaction  1520 , provide a protection object  1550  representing (or informing) that the content (e.g., the second content  1520 ) was configured to be protected (or hidden) in association (or mapping) with the corresponding content. An example of this is shown in  FIG.  15 C . 
       FIG.  15 B  shows an example of configuring content (e.g., the second content  1520 ) to be protected (or hidden), based on the first interaction  1540  by the user. With regard to the protection (or hiding) configuration of the content, if a profile of the content belongs to a specified profile, the content may be automatically configured to be protected (or hidden) without user intervention (e.g., input of the first interaction  1540 ). The AR providing device may identify whether or not the content (e.g., the second content  1520 ) has a specified profile and, based on identifying that the content has a specified profile, automatically provide a protection object  1550  indicating (or informing) that the content (e.g., the second content  1520 ) was configured to be protected (or hidden) in association (or mapping) with the content. An example of this is shown in  FIG.  15 C . 
     Referring to  FIG.  15 C , the AR providing device may display the protection object  1550  in association with the second content  1520 , which is the corresponding content, based on the detection of the first interaction  1540  or the detection of a specified profile. For example, the AR providing device may provide the protection object  1550  to be associated with the second content  1520  so that the user may intuitively recognize the protection-specified content among a variety of content provided on the AR screen  1500 . The protection object  1550  may be provided in various forms to intuitively indicate that the corresponding content is configured to be protected (or hidden) and is invisible in the real space. For example, the protection object  1550  may include static or dynamic text and/or images, and may be provided in various shapes. The protection object  1550  may be provided to at least partially overlap the corresponding content. 
     Referring to  FIG.  15 D , the AR providing device may detect a second interaction  1560  of triggering an operation (e.g., an operation trigger) of displaying at least one piece of content (e.g., the first content  1510  or the second content  1520 ) selected by the user through a specified target device. For example, the user may select and determine the first content  1510  and the second content  1520  on the AR screen  1500  and input a specified second interaction  1560  (e.g., a rollable extension gesture, another specified touch gesture, or a voice-based command) for displaying the selected first content  1510  and second content  1520  through the target device. 
     The AR providing device may determine a target device for displaying content, based on the detection of the second interaction  1560 . The AR providing device may determine a display mode (e.g., a first display mode or a second display mode) corresponding to a target device for displaying the content selected by the user. For example, the AR providing device may determine a display mode and a target device corresponding thereto, based on a processing entity of the content. 
     The AR providing device may provide content to correspond to the first display mode or the second display mode through the target device. For example, the AR providing device may display content in a first display mode in which the content is provided through a real display area based on the display module  160  of the electronic device  101  in the real space. As another example, the AR providing device may display content in a second display mode in which the content is mapped and provided through a virtual display area configure based on the electronic device  101  in the AR screen  1500  of the wearable electronic device  301 . Examples of this are shown in  FIGS.  15 E and  15 F . 
       FIG.  15 E  shows an example of providing content according to the first display mode. Referring to  FIG.  15 E , based on the determination of the first display mode, the AR providing device may perform processing to display the first content  1510  not configured to be protected and to not display the second content  1520  configured to be protected (e.g., protected content or hidden content), among the content (e.g., the first content  1510  and the second content  1520 ) selected and determined by the user on the AR screen  1500 , based on a substantial display area (e.g., a default area and an extension area that is extended by sliding-out) corresponding to the display module  160  of the electronic device  101 . 
     According to the first display mode, the AR providing device may operate to continuously display the first content  1510  and the second content  1520  selected and determined by the user on the AR screen  1500  through the display module  160  of the electronic device  101  in the real space such that only the first content  1510  is displayed on the display module  160 , instead of displaying the second content  1520  configured to be protected in the AR screen  1500 . 
     Referring to  FIG.  15 E , the electronic device  101  may turn on and extend the display module  160 , display the first content  1510  in the area (e.g., the first extension area) for first content  1510 , instead of displaying the second content  1520  in the area (e.g., the second extension area) for the second content  1520 , among specified areas (e.g., the default area and/or the extension area) of the display module  160 , and provide the second extension area as an empty space  1525  or by inactivating (or turning off). 
       FIG.  15 F  shows an example of providing content according to the second display mode. 
     Referring to  FIG.  15 F , based on the determination of the second display mode, the AR providing device may display the content (e.g., the first content  1510  and the second content  1520 ), based on a virtual area associated with the electronic device  101 , on the AR screen  1500  provided through the display module  520  of the wearable electronic device  301 . For example, the AR providing device may display both the first content  1510  not configured to be protected and the second content  1520  configured to be protected (e.g., protected content or hidden content) according to the second display mode. 
     According to the second display mode, the AR providing device may operate to map (e.g., texture-map) the first content  1510  and the second content  1520  selected and determined by the user from the AR screen  1500  to the default area of the electronic device  101  positioned in the real space displayed on the AR screen  1500 , the extension area of the electronic device  101 , and/or the virtual area produced adjacent to the electronic device  101  and display the same thereon. 
     Referring to  FIG.  15 F , the electronic device  101  may turn on and extend the display module  160 , display the first content  1510  in the area (e.g., the first extension area) for first content  1510 , and display the second content  1520  in the area (e.g., the second extension area) for the second content  1520 , among specified areas (e.g., the default area and/or the extension area) of the display module  160 . For example, the AR providing device may map and display the first content  1510  and the second content  1520  selected and determined by the user through the entirety or at least a portion of the default area of the electronic device  101 , the extension area thereof, and/or the virtual area within the AR screen  1500  (e.g., a virtual space) according to the second display mode. 
     The element  1590  may show an example of a display state of the display module  160  of the electronic device  101  viewed in the real space, instead of the electronic device  101  on the AR screen  1500  provided through the display module  520  of the wearable electronic device  301 . As illustrated, the electronic device  101  may display a screen being executed (or operated) in the electronic device  101  shown in  FIG.  15 A  through a default area or the entire area or maintain the display in the default area and provide a blank screen or a specified screen to an extension area  1595  corresponding to extension of the display module  160  (e.g., an area extended by sliding-out). For example, the electronic device  101  may provide, as a specified screen, a screen resulting from execution of a specified function in response to extension of the display module  160  (e.g., a split screen based on execution of a specified application or the entire screen of a running application (e.g., display the screen displayed in the default area into a full screen)). The display module  160  of the electronic device  101  in the real space may be in the state of being turned off. 
     For example, in the second display mode, the screen (e.g., the display screen of the first content  1410 ) displayed based on the display module  160  of the electronic device  101  on the AR screen  1500  and the screen displayed through the display module  160  of the electronic device  101  in the real space may be different, and the display module  160  of the electronic device  101  may not display the content (e.g., the first content  1410 ) on the AR screen  1500  in the real space. 
     The AR providing device may provide the display based on the electronic device  101  and the display based on the wearable electronic device  301  to be different depending on whether or not the content (e.g., the first content  1510  and the second content  1520 ) selected and determined on the AR screen  1500  is configured to be protected. For example, as shown in  FIG.  15 E , the content (e.g., the second content  1520 ) configured to be protected may not be displayed through the display module  160  of the electronic device  101  in the real space. For example, as shown in  FIG.  15 F , the content (e.g., the second content  1520 ) configured to be protected may be mapped and displayed onto the display module  160  of the electronic device  101  only in the user&#39;s virtual space of the AR screen  1500  so that only the user wearing the wearable electronic device  301  is able to see the same. 
       FIG.  16    is a diagram illustrating an operation method between an electronic device and a wearable electronic device according to an embodiment of the disclosure. 
     Referring to  FIG.  16   , the illustrated operations show an example of providing content through the electronic device  101  or the wearable electronic device  301 , based on a display mode (e.g., a first display mode or a second display mode), in an environment in which the electronic device  101  and the wearable electronic device  301  provide AR services based on the tethered method. 
     Operations performed by the electronic device  101  to be described below may be executed by the processor  120  of the electronic device  101  including various processing circuits and/or executable program elements of the electronic device  101 . Operations performed by the wearable electronic device  301  to be described below may be executed by the processor  590  of the wearable electronic device  301  including various processing circuits and/or executable program elements of the wearable electronic device  301 . 
     Referring to  FIG.  16   , in operation  1601 , the electronic device  101  and the wearable electronic device  301  may be connected through a specified communication method. For example, the electronic device  101  and the wearable electronic device  301  may be connected (e.g., paired) by wired or wireless communication. For example, the electronic device  101  and the wearable electronic device  301  may be connected to each other through short-range wireless communication such as Bluetooth, Bluetooth Low Energy, Wi-Fi, Wi-Fi Direct, or ultra-wide band (UWB), or wired communication such as USB. The electronic device  101  may include a smartphone, a tablet personal computer (PC), and/or a notebook computer. The wearable electronic device  301  may include AR glasses, smart glasses, or a head mounted display (HMD). 
     In operation  1603 , the electronic device  101  (or the processor  120  of the electronic device  101 ) may execute a related application for an AR service. For example, the electronic device  101  may execute an application, based on a user input for manipulating execution of the application in the electronic device  101  or reception of a request for instructing execution of the application from the wearable electronic device  301 . 
     In operation  1605 , the electronic device  101  may transmit content to the wearable electronic device  301 , based on the execution of the application. For example, the electronic device  101  may process content for an AR service. The electronic device  101  may transmit related content data to the wearable electronic device  301  through specified communication to display the content on the wearable electronic device  301 . 
     In operation  1607 , the wearable electronic device  301  (or the processor  590  of the wearable electronic device  301 ) may display the content on an AR screen. For example, the wearable electronic device  301  may be in the state of being worn on the user&#39;s body (e.g., a face), and the content received from the electronic device  101  may be superimposed on the real world and displayed through the display module  520  as a single image (e.g., an AR screen). The wearable electronic device  301  may receive content (e.g., image data or AR images) from the electronic device  101  and display the received content together with various objects in the real world through the display module  520 . 
     In operation  1609 , the wearable electronic device  301  may produce AR information. For example, the AR information may include information about a target object recognized by the wearable electronic device  301  on the AR screen, interaction information related to the user&#39;s action according to the user&#39;s gesture input and/or eye tracking on the AR screen, object information about an object recognized on the AR screen, position information (e.g., coordinates and/or spatial information) about an object recognized on the AR screen, and/or position information about content displayed on the AR screen. 
     The interaction may include a first interaction of recognizing the electronic device  101  entering the real space of the AR screen provided through the display module  520  of the wearable electronic device  301 , a second interaction of recognizing a specified gesture (e.g., a slide-out gesture or a rollable extension gesture) input by the user using the electronic device  101  after the entry of the electronic device  101 , or a third interaction of recognizing a specified menu manipulation gesture (e.g., a touch input) input by the user through the electronic device  101  onto the AR screen after the entry of the electronic device  101 . 
     The second interaction may include a gesture of substantially extending an extension area of the electronic device  101 . In another embodiment, the second interaction may not be a substantial extension of the extension area of the electronic device  101 . For example, the user may input only an extending gesture without substantially extending the electronic device  101 , and the wearable electronic device  301  may recognize the user&#39;s gesture to identify the second interaction. In an embodiment, the wearable electronic device  301  may detect a user&#39;s gesture according to the second interaction and/or the third interaction, based on the user hand detecting and/or hand tracking on the AR screen. 
     In operation  1611 , the wearable electronic device  301  may transmit AR information to the electronic device  101 . For example, the wearable electronic device  301  may transmit AR information to the electronic device  101  through specified communication. The AR information may be transmitted in real time, periodically, or based at least on the time of obtaining new information according to various state changes on the AR screen. 
     In operation  1613 , the electronic device  101  may detect a specified interaction. For example, the electronic device  101  may receive AR information from the wearable electronic device  301  and analyze the received AR information to detect a specified interaction. The specified interaction may indicate an operation trigger for determining a display mode for displaying the content. The electronic device  101  may identify a specified interaction (or trigger) in which the electronic device  101  is positioned on the user&#39;s gaze, based on AR information, while the content is displayed on the AR screen through the wearable electronic device  301 . 
     The electronic device  101 , based on the AR information, may identify a first interaction in which the electronic device  101  enters the real space of the AR screen provided through the display module  520  of the wearable electronic device  301 , a second interaction related to a specified gesture (e.g., a slide-out gesture or a rollable extension gesture) input by the user using the electronic device  101  after the entry of the electronic device  101 , or a third interaction related to a specified menu manipulation gesture (e.g., a touch input) input by the user through the electronic device  101  onto the AR screen after the entry of the electronic device  101 . 
     In operation  1615 , the electronic device  101  may determine a display mode of the content, based on the detection of a specified interaction. For example, the electronic device  101  may detect (or recognize) a specified interaction and, in response to the detection of the specified interaction, determine a display mode to display content to correspond to at least one specified condition. The electronic device  101  may determine a display mode for displaying content, based at least on a processing entity for processing content being executed in relation to an AR service and/or a specified profile. 
     If the electronic device  101  detects a specified interaction, the electronic device  101  may determine a display mode (e.g., a first display mode or a second display mode) for displaying information on content depending on a processing entity for processing content being executed in relation to an AR service. According to various embodiments of the disclosure, the display mode may include a first display mode (e.g., including a mirroring-based display mode) of displaying content on the AR screen through the display module  160  of the electronic device  101  or a second display mode of mapping the content on the AR screen to the electronic device  101  on the AR screen in a virtual space (e.g., an AR screen) through the display module  520  of the wearable electronic device  301  and displaying the same therein, depending on the processing entity of content. 
     For example, in the case of the tethered method, the processing entity of content or an application of the content may be the electronic device  101 , and the first display mode may be determined as the display mode of the content. Even in the tethered method, if the wearable electronic device  301  is able to perform processing (e.g., switching of a processing entity) according to the properties of content, or if a target device to display content is explicitly designated as the wearable electronic device  301  according to the user&#39;s intention (e.g., the AR environment continues to be used), the second display mode may be determined as the display mode of the content. 
     In the case of the standalone method, the processing entity of content or an application of the content may be the wearable electronic device  301 , and the second display mode may be determined as the display mode of the content. For example, even in the standalone method, if the electronic device  101  is able to perform processing (e.g., switching of a processing entity) according to the properties of content, or if a target device to display content is explicitly designated as the electronic device  101  according to the user&#39;s intention (e.g., mirroring or substantial extension of the display module  160  of the electronic device  101  in the real space), the first display mode may be determined as the display mode for displaying the content. 
     The display mode determined according to the processing entity may vary depending on whether a profile of the content corresponds to a profile specified in advance. For example, if the content corresponds to a specified profile, a display mode (e.g. the second display mode) using a virtual space for the corresponding content (e.g., content of the specified profile) may be determined, regardless of whether the processing entity is the electronic device  101  or the wearable electronic device  301 . 
     In operation  1617 , based on the determination result, the electronic device  101  may determine whether the display mode is the first display mode or the second display mode. Based on the determined display mode (e.g., the first display mode or the second display mode), the electronic device  101  may operate to display the content through the display module  160  of the electronic device  101  (e.g., the first display mode) or display the content on an AR screen through the display module  520  of the wearable electronic device  301  (e.g., the second display mode). 
     If the display mode is determined to be the first display mode in operation  1617 , the electronic device  101  may configure an active window, based on a specified area of the display module  160  of the electronic device  101 , in operation  1621 . For example, the electronic device  101  may determine an area corresponding to the position and/or size determined for the content on the AR screen, among a substantial display area (e.g., a default area and/or an extension area extended according to sliding-out) in the display module  160 , as a specified area for displaying the content. The electronic device  101  may identify a specified area in the display module  160  (e.g., identify the default area and/or the extension area) and configure the specified area as an active window for content. 
     If the display mode is determined to be the first display mode, the electronic device  101  may operate to provide information indicating operation in the first display mode to the wearable electronic device  301  and display the same through the wearable electronic device  301 . For example, based on the determination of the first display mode, the electronic device  101  may operate to display, through the wearable electronic device  301 , a guide stating that the content is to be displayed through the electronic device  101  due to switching to the first display mode so that the wearable electronic device  301  is to be taken off, thereby providing the same to the user. 
     Based on the determination of the first display mode, the electronic device  101  may transmit a related command instructing to stop displaying the screen of the wearable electronic device  301  (e.g., turn off the display module  520  or the wearable electronic device  301 ) to the wearable electronic device  301  together with the guide or subsequently thereto. For example, the wearable electronic device  301  may operate to receive a guide and a control command from the electronic device  101 , display the guide for a predetermined period of time, and then stop displaying the screen according to the control command As another example, the wearable electronic device  301  may operate to automatically stop displaying the screen if it is taken off by the user. 
     In operation  1623 , the electronic device  101  may provide (e.g., display) the content through the active window in the display module  160 . 
     In operation  1625 , the electronic device  101  may process a user interaction (e.g., a user&#39;s touch input based on the displayed content) input through the electronic device  101 . The electronic device  101  may operate to detect a user interaction for controlling a function related to the content displayed through the display module  160  and process a function corresponding to the user interaction. The electronic device  101  may recognize a point (e.g., a touch point) where a user interaction is detected in the content, process the user interaction to execute a related function, based on the recognized result (e.g., touch input coordinates), and display content according to the processing result through the display module  160 . 
     If the display mode is determined to be the second display mode in operation  1617 , the electronic device  101  may map the active window, based on the electronic device  101  of the AR screen, in operation  1631 . For example, the electronic device  101  may identify the state of the electronic device  101  on the AR screen (e.g., position, whether it is extended, and/or whether it is virtually extended), based on the AR information, and determine information (e.g., a position and/or size) of a virtual area for displaying the content on the AR screen, based on the identification result. According to an embodiment, the electronic device  101  may map the active window, based on the determined information on the virtual area. 
     In operation  1633 , the electronic device  101  may transmit mapping information to the wearable electronic device  301 . For example, the electronic device  101  may produce mapping information related to mapping of an active window and transmit the mapping information to the wearable electronic device  301  through specified communication. 
     In operation  1635 , the wearable electronic device  301  may provide content through the active window on the AR screen. For example, the wearable electronic device  301  may receive mapping information from the electronic device  101  and, based on the mapping information, map the active window, based on the electronic device on the AR screen. The wearable electronic device  301  may operate to map and display the content, based on the active window of the AR screen. 
     In operation  1637 , the wearable electronic device  301  may process a user interaction input onto the AR screen (e.g., a user&#39;s gesture input based on the content displayed on the AR screen). The wearable electronic device  301  may track and detect a user interaction for controlling a function related to the content on the AR screen. The wearable electronic device  301  may track and detect the user input, based on technologies such as gaze tracking and object recognition, calculate a point (e.g., a touch point) where the user interaction is detected in the content on the AR screen, and transmit related information (or interaction input information) (e.g., coordinates and/or spatial information) to the electronic device  101 . 
     The electronic device  101  may recognize a point (e.g., a touch point) where a user interaction is detected in the content of the AR screen, based on the related information received from the wearable electronic device  301 , perform processing to execute a related function, based on the recognized result, and transmit content data according to the processing result to the wearable electronic device  301 . The wearable electronic device  301  may receive the content data from the electronic device  101  and reflect the received content data to content on the AR screen, thereby displaying a result screen thereof (e.g., a screen in which the content data is mapped to the electronic device  101  on the AR screen). 
     The wearable electronic device  301  may perform a user interaction for the content on the AR screen by the electronic device  101  even in the second display mode. For example, the user may perform user interaction through the electronic device  101  in the real space even in the second display mode, and the electronic device  101  may process a function corresponding to the user interaction and may transmit related content data to the wearable electronic device  301  through specified communication connecting the wearable electronic device  301  and the electronic device  101 . The wearable electronic device  301  may operate to receive and display the content data processed according to the user interaction from the electronic device  101 , thereby providing a processing result of the user interaction in the electronic device  101 .

     In operation  1703 , the wearable electronic device  301  (or the processor  590  of the wearable electronic device  301 ) may execute an AR service. For example, the wearable electronic device  301  may execute an application related to an AR service, based on a user input for manipulating execution of the application in the wearable electronic device  301  or reception of a request for instructing execution of an AR service from the electronic device  101 . 
     In operation  1705 , the wearable electronic device  301  may display content on the AR screen, based on the execution of the AR service. For example, the wearable electronic device  301  may process content for an AR service. According to an embodiment, the wearable electronic device  301  may be in the state of being worn on the user&#39;s body (e.g., a face) and display content (e.g., image data or AR images) through the display module  520  together with various objects in the real world.

The specified interaction may indicate an operation trigger for determining a display mode for displaying content. The wearable electronic device  301  may identify a specified interaction (or trigger) in which the electronic device  101  is positioned on the user&#39;s gaze while the content is displayed on the AR screen. For example, the wearable electronic device  301  may identify a first interaction in which the electronic device  101  enters the real space of the AR screen provided through the display module  520  of the wearable electronic device  301 , a second interaction related to a specified gesture (e.g., a slide-out gesture or a rollable extension gesture) input by the user using the electronic device  101  after the entry of the electronic device  101 , or a third interaction related to a specified menu manipulation gesture (e.g., a touch input) input by the user through the electronic device  101  onto the AR screen after the entry of the electronic device  101 . 
     In operation  1709 , the wearable electronic device  301  may determine a display mode of content, based on the detection of the specified interaction. For example, the wearable electronic device  301  may detect (or recognize) a specified interaction and, in response to the detection of the specified interaction, determine a display mode for displaying content corresponding to at least one specified condition. The wearable electronic device  301  may determine a display mode for displaying content, based at least on a processing entity for processing content being executed in relation to an AR service and/or a specified profile. 
     If the wearable electronic device  301  detects a specified interaction, the wearable electronic device may determine a display mode (e.g., a first display mode or a second display mode) for displaying information on content depending on a processing entity for processing content being executed in relation to an AR service. According to various embodiments of the disclosure, the display mode may include a first display mode (e.g., including a mirroring-based display mode) of displaying content on the AR screen through the display module  160  of the electronic device  101  or a second display mode of mapping the content on the AR screen to the electronic device  101  on the AR screen in a virtual space (e.g., an AR screen) through the display module  520  of the wearable electronic device  301  and displaying the content therein, depending on the processing entity of content 
     For example, in the case of the tethered method, the processing entity of content or an application of the content may be the electronic device  101 , and the first display mode may be determined as the display mode of the content.

The electronic device  101  may transmit related information (or interaction input information) (e.g., coordinates and/or spatial information) about the point where the user interaction is detected to the wearable electronic device  301 . 
     The wearable electronic device  301  may recognize the point (e.g., a touch point) where the user interaction is detected in the content of the AR screen, based on the related information received from the electronic device  101 , and perform processing to execute a related function, based on the recognized result. The wearable electronic device  301  may transmit content data according to the processing result to the electronic device  101 . 
     The electronic device  101  may receive the content data from the wearable electronic device  301 . The electronic device  101  may reflect the received content data to the content on the display module  160 , thereby displaying a result screen thereof (e.g., a screen on which content data is reflected). 
       FIGS.  18 A to  18 C  are diagrams illustrating examples of operating a display mode between an electronic device and a wearable electronic device according to various embodiments of the disclosure. 
       FIGS.  18 A,  18 B, and  18 C  show examples of providing content through an electronic device  101 , based on determination of a first display mode, in an environment in which an electronic device  101  and a wearable electronic device  301  provide an AR service, based on a tethered method or a standalone method.  FIGS.  18 A,  18 B, and  18 C  show examples in which the form factor of the electronic device  101  is a rollable type. 
       FIG.  18 A  shows an example in which the electronic device  101  enters an AR screen  1800  through the display module  520  of the wearable electronic device  301  and in which the user performs specified interaction (e.g., a rollable activation interaction) for the electronic device  101  on the AR screen  1800 . For example, the user may move the electronic device  101  into the AR screen  1800 , and then input a specified gesture (e.g., a slide-out gesture or a rollable extension gesture) using the electronic device  101 . 
     Referring to  FIG.  18 A , the specified gesture may include a gesture of substantially extending the extension area of the electronic device  101  (e.g., substantially sliding out the display module  160  of the electronic device  101 ). The specified gesture may not be a substantial extension of the extension area of the electronic device  101 . For example, the user may input only an extending gesture without substantially extending the electronic device  101 . In an embodiment, the specified gesture may be detected based on the user&#39;s hand detection and/or hand tracking on the AR screen  1800 . 
       FIGS.  18 B and  18 C  show examples of providing content, which is being operated (e.g., displayed) through the AR screen  1800 , through the actual display module  160  of the electronic device  101  in the real space (e.g., a first display mode), based on the display mode determined as a first display mode. 
       FIG.  18 B  shows an example in which the display module  160  of the electronic device  101  is extended in response to a specified interaction and in which the content  1810  being operated on the AR screen  1800  is displayed through an extension area B of the display module  160 . The electronic device  101  may maintain the existing state of a default area A of the display module  160  and provide the extension area B that is extended according to a specified interaction as an active window for displaying the content  1810 . 
       FIG.  18 C  shows an example in which the display module  160  of the electronic device  101  is extended in response to a specified interaction and in which the content  1820  being operated on the AR screen  1800  is displayed through the entire area including the default area A and the extension area B of the display module  160 . For example, the specified interaction by the user may reflect a clear intention of the user for extension of a screen. Accordingly, the electronic device  101  may provide the entire area (e.g., default area A+extension area B) including the default area A and the extension area B of the display module  160  as an active window to display the content  1820 . 
     An active window may be configured in at least one of the default area A, the extension area B, or the entire area (e.g., default area A+extension area B) of the electronic device  101 , based on the overlapping state (or overlapping area) of an affordance according to the user&#39;s intention and the content. If the content  1810  and  1820  overlaps the affordance, an active window may be configured based on the extension area B such that the corresponding content is to be displayed in the extension area B of the electronic device  101 . If the content  1810  and  1820  overlaps both the electronic device  101  (e.g., the default area A of the electronic device  101 ) and the affordance on the AR screen, an active window may be configured based on the entire area (e.g., default area A+extension area B) of the electronic device  101  such that the corresponding content is to be displayed in the entire area. If one piece of content  1810  or  1820  is disposed in the affordance, the active window may be configured based on the entire area (e.g., default area A+extension area B) of the electronic device  101  such that the corresponding content is to be displayed in the entire area. 
     If a plurality of pieces of content (e.g., first content and second content) overlaps the affordance, an active window may be configured based on each of the default area A and the extension area B such that the plurality of pieces of content is to be separately displayed in the default area A and the extension area B of the electronic device  101 . One piece of content (e.g., first content) among a plurality of pieces of content overlaps the affordance and if another piece of content (e.g., second content) thereof overlaps the electronic device  101  (e.g., the default area A of the electronic device  101 ), for example, if each piece of content is disposed according to the user&#39;s intention, a first active window for the first content may be configured in the extension area B and a second active window for the second content may be configured in the default area A so as to display the first content and the second content to conform to the disposition according to the user&#39;s intention. 
     The affordance may be varied (e.g., extended) by a user input (e.g., an affordance extension interaction). If one piece of content (e.g., first content) is disposed in (e.g., overlaps) the extended affordance, the display module  160  of the electronic device  101  may be extended to correspond to the extended affordance and an active window may be configured so as to display one piece of content on the entire extended screen through the entire area (e.g., default area A+extension area B) including the extended extension area B and the default area A. If a plurality of pieces of content (e.g., first content and second content) is disposed in (e.g., overlaps) the extended affordance, an active window may be configured in each of the default area A and the extension area B so as to display the plurality of pieces of content in the default area A and the extension area B, respectively, or at least one active window may be configured in the extension area so as to display the plurality of pieces of content in the extension area B corresponding to the extended affordance. 
     If the electronic device  101  and/or the wearable electronic device  301  determines to display content, based on the first display mode, during operation for the AR service, it may operate to stop displaying the AR screen  1800  of the wearable electronic device  301 , configure a specified active window for the content being displayed on the AR screen through the default area and/or the extension area of the display module  160  of the electronic device  101 , and display content based on the configured active window. 
       FIGS.  19 A and  19 B  are diagrams illustrating an example of operating a display mode between an electronic device and a wearable electronic device according to various embodiments of the disclosure. 
       FIGS.  19 A and  19 B  show examples of providing content through a wearable electronic device  301 , based on determination of a second display mode, in an environment in which an electronic device  101  and a wearable electronic device  301  provide an AR service, based on a tethered method or a standalone method.  FIGS.  19 A and  19 B  show examples in which the form factor of the electronic device  101  is a rollable type. 
       FIG.  19 A , shows an example of mapping (e.g., texture-mapping) content  1910  to the extension area of the electronic device  101  on the AR screen  1900  and displaying the same. Referring to  FIG.  19 B ,  FIG.  19 B  shows a state of the electronic device  101  viewed in the real space, which may, as shown, show an example of the state in which content is not displayed in the extension area of the electronic device  101  in the real space. 
     Referring to  FIGS.  19 A and  19 B , if the electronic device  101  and/or the wearable electronic device  301  determines to display content, based on the second display mode, during operation for an AR service, content  1910  may be displayed in association with the electronic device  101  only through the AR screen  1900  of the wearable electronic device  301 , for example, through the extension area of the display module  160  of the electronic device  101  on the AR screen  1900 . Unlike this, the electronic device  101  in the real space may provide a corresponding area  1920  (e.g., the extension area) as an empty space or inactive space (or to be turned off), instead of displaying the content  1910  displayed through the AR screen  1900 . 
     As shown in  FIGS.  19 A and  19 B , a first user wearing the wearable electronic device  301  may check and control the content  1910  on the AR screen  1900 , whereas at least one second user in the real space is unable to check the content  1910  through the electronic device  101 . 
     When providing the content  1910  to the AR screen  1900  based on the second display mode, the electronic device  101  and/or the wearable electronic device  301  may further provide graphic processing for an area to which the content  1910  is mapped in the display module  160  of the electronic device  101  on the AR screen  1900 . For example, in order to secure the user&#39;s visibility, the color (e.g., background color) of the area to which the content  1910  is mapped in the display module  160  of the electronic device  101  on the AR screen  1900  may be virtually changed. It is possible to provide a graphic effect of providing the background of the area where the content  1910  is mapped and displayed as a color contrasting to a representative color of the content  1910  (e.g., a dominant color). 
       FIGS.  20 A to  20 C  are diagrams illustrating an example of operating content mirroring and interaction between an electronic device and a wearable electronic device according to various embodiments of the disclosure. 
       FIGS.  20 A,  20 B, and  20 C  show examples of performing mirroring of at least one piece of content on an AR screen to an electronic device  101  through a wearable electronic device  301  and controlling at least one piece of content on the AR screen, based on an interaction input through the electronic device  101 , in an environment in which the electronic device  101  and the wearable electronic device  301  provide an AR service, based on a tethered method or a standalone method. 
     Referring to  FIGS.  20 A to  20 C , the electronic device  101  and/or the wearable electronic device  301  may execute a mirroring function based on a user&#39;s intention while displaying content through the AR screen according to the second display mode. For example, the user may be in the state of using an AR service by an application that is operable only in the wearable electronic device  301 . The user may activate a mirroring function to display the content on the AR screen through the display module  160  of the electronic device  101 . In an embodiment, the mirroring function may include, for example, a function of mirroring content (e.g., mirror content) according to an application operable in the wearable electronic device  301  on the electronic device  101  while displaying the content through the AR screen, thereby displaying the content through the display module  160  of the electronic device  101  as well. 
     The wearable electronic device  301  may mirror a variety of control information (e.g., components, objects, and/or windows) that the user may check and control through the wearable electronic device  301  on the electronic device  101  to be displayed thereon. 
     The mirroring function may enable the wearable electronic device  301  to perform processing on the content and the electronic device  101  to display the content transmitted (or mirrored) from the wearable electronic device  301 . 
     Referring to  FIGS.  20 A to  20 C , the electronic device  101  may display content  2010  transmitted from the wearable electronic device  301  through the display module  160 . The user may use the electronic device  101  to control content displayed on the AR screen of the wearable electronic device  301 . For example, the user may input various gestures (e.g., touch gestures) related to control of the content on the AR screen, based on the content  2010  displayed on the display module  160  of the electronic device  101 . 
     The user may perform, with respect to the content  2010  displayed on the display module  160  of the electronic device  101 , a first gesture input (e.g.,  FIG.  20 A ) for rotating the content  2010  by a screen touch operation, a second gesture input (e.g.,  FIG.  20 B ) for enlarging the content  2010  by a screen zoom-in operation (e.g., pinch zoom-in), or a third gesture input (e.g.,  FIG.  20 C ) for reducing the content  2010  by a screen zoom-out operation (e.g., pinch zoom-out). 
     Various gestures related to content control in the disclosure are not limited thereto. The various gestures may include a gesture of moving the content  2010  up, down, left, and right by a screen move operation or a gesture of moving the content  2010  back and forth by a screen multi-touch move operation may be included. 
     The electronic device  101  may detect a user input shown in  FIGS.  20 A,  20 B , and/or  20 C, calculate a point (e.g., a touch point) where the user input is detected in the content on the display module  160 , and transmit related information (e.g., coordinates and/or spatial information) to the electronic device  101 . The wearable electronic device  301  may convert the related information received from the electronic device  101  into coordinate information on the AR screen and process the converted coordinate information as a user input for controlling the content of the AR screen. 
     The wearable electronic device  301  may perform processing of controlling the content of the AR screen (e.g., execute a related function) to correspond to the user input based on the electronic device  101  and reflect the same on the content on the AR screen, thereby displaying a result screen thereof. For example, the wearable electronic device  101  may recognize a user input shown in  FIGS.  20 A,  20 B , and/or  20 C and, in response thereto, rotate, enlarge, or reduce the content on the AR screen, thereby displaying a result screen thereof 
       FIGS.  21 A to  21 C  are diagrams illustrating an example of an operation of sharing content between an electronic device and a wearable electronic device according to various embodiments of the disclosure. 
       FIGS.  21 A,  21 B, and  21 C  show examples of providing content through an wearable electronic device  301 , based on determination of a second display mode, and sharing at least a portion of content provided through the wearable electronic device  301  with an electronic device  101  in the real space in an environment in which the electronic device  101  and the wearable electronic device  301  provide an AR service, based on a tethered method or a standalone method. According to an embodiment,  FIGS.  21 A,  21 B, and  21 C  may show an example in which the form factor of the electronic device  101  is a rollable type. 
     Referring to  FIG.  21 A , shows an example of mapping (e.g., texture-mapping) content  2110  to an extension area of the electronic device  101  on an AR screen  2100  and displaying the content. Referring to  FIG.  21 B ,  FIG.  21 B  shows a state of the electronic device  101  viewed in the real space, which may, as shown, show an example of the state in which content is not displayed in the extension area of the electronic device  101  in the real space. 
     Referring to  FIGS.  21 A and  21 B , if the electronic device  101  and/or the wearable electronic device  301  determines to display content, based on the second display mode, during operation for an AR service, content  2110  may be displayed in association with the electronic device  101  only through the AR screen  2100  of the wearable electronic device  301 , for example, through the extension area of the display module  160  of the electronic device  101  on the AR screen  2100 . Unlike this, the electronic device  101  in the real space may provide a corresponding area  2120  (e.g., the extension area) as an empty space or inactive space (or to be turned off), instead of displaying the content  2110  displayed through the AR screen  2100 . 
     Referring to  FIGS.  21 A and  21 B , a first user wearing the wearable electronic device  301  may check and control the content  2110  on the AR screen  2100 , whereas at least one second user in the real space is unable to check the content  2110  through the electronic device  101 . 
     In the environment referring to  FIGS.  21 A and  21 B , the electronic device  101  and/or the wearable electronic device  301  may execute a sharing function based on the user&#39;s intention while displaying the content  2110  through the AR screen  2110 . The user may activate a sharing function that enables the content  2110  (or at least a portion (e.g., content data) of the content  2110 ) on the AR screen  2100  to be shared with the electronic device  101  (e.g., transmission of content data of the content  2110  (or file transmission) or partial disclosure thereof through the display module  160  of the electronic device  101 ). In an embodiment, the sharing function may include, for example, a function in which the wearable electronic device  301  transmits the content  2110  (or at least a portion of the content  2110 ) to the electronic device  101  while displaying the content  2110  on the AR screen  2100  to be shared with the electronic device  101 . 
     Referring to  FIG.  21 A , the electronic device  101  and/or the wearable electronic device  301  may process a user interaction for the content  2110  mapped to the electronic device  101  on the AR screen  2100  (e.g., a user&#39;s gesture input based on the content displayed on the AR screen  2100 ). The electronic device  101  and/or the wearable electronic device  301  may operate to track and detect a user interaction for executing a sharing function to share the content  2110  (e.g., at least a portion of the content  2110 ) on AR screen  2100  and process a function of sharing the content  2110  with the electronic device  101  in response to the user interaction. 
     The user may input a gesture of selecting a specific object (e.g., text and/or an image) from the content  2110  mapped to a second area (e.g., the extension area) of the electronic device  101  on the AR screen  2100  and dragging the same to a first area (e.g., the default area) (e.g., a gesture of dragging from the right area to the left area with reference to the example in  FIG.  21 A ). The wearable electronic device  301  may track and detect a user input related to a gaze sharing function and transmit the content  2110  (e.g., a selected specific object) at a point (e.g., a touch point) where the user input is detected on the AR screen  2100  to the electronic device  101  through specified communication. 
     The electronic device  101  may operate to detect reception of the content  2110  (e.g., at least a portion of the content  2110 ) from the wearable electronic device  301 , store the received content  2110  in the memory  130  of the electronic device  101 , and/or display the same through the display module  160 . If the content  2110  is received from the wearable electronic device  301 , as shown in  FIG.  21 C , the electronic device  101  may provide information from the wearable electronic device  301 , stating that the content  2110  is to be shared, to the user in a specified form (e.g., in a pop-up form). For example, the electronic device  101  may provide a guide window  2150  in the form of a pop-up, which informs that there is content  2110  to be shared with the wearable electronic device  301  and enables receiving and storing the shared content  2110  or rejecting (cancelling) the reception of the shared content  2110 . 
     When providing the guide window  2150  related to the content  2110  shared by the user, as shown in  FIG.  21 C , the electronic device  101  may provide the guide window  2150  as a pop-up while maintaining the state shown in  FIG.  21 B  (e.g., the inactive state of the extension area). If reception and storage of the shared content  2110  is selected by the user, the electronic device  101  may receive the shared content  2110  from the wearable electronic device  301  and store the same in the memory  130 . The electronic device  101  may provide (e.g., display) the content  2110 , which is received and stored, through a default area (e.g., the left area in  FIG.  21 A ) of the display module  160 . For example, the electronic device  101  may display the shared content  2110  through the default area while maintaining the inactive state of the extension area. Assuming a state in which the electronic device  101  displays a chat window through the default area, the electronic device  101  may operate to reflect the shared content  2110  from the wearable electronic device  301  on the chatting window in the form of an attached file and display the same within the chat window of the default area. 
     A method of providing an augmented reality (AR) service according to an embodiment of the disclosure may include providing content through an AR screen, detecting a specified external object through the AR screen while providing the content, determining a display mode for providing the content, based on the detection of the specified external object, and, based on the determined display mode, performing control to display the content through a display module of the specified external object (e.g., the display module  160  of the electronic device  101 ) or performing control to display the content through a virtual display area associated with the specified external object on the AR screen. 
     The detecting of the external object may include detecting a specified interaction through the AR screen. 
     The determining of the display mode may include determining whether a target device processing the content is an electronic device  101  or a wearable electronic device  301 , based on the detection of the specified interaction, if the target device is determined to be the electronic device  101 , determining a first display mode in which the content on the AR screen switches to be displayed through the electronic device  101 , and if the target device is determined to be the wearable electronic device  301 , determining a second display mode in which the content is mapped to the electronic device  101  and displayed on the AR screen. 
     The performing control to display the content may include, based on the determination of the first display mode, performing control to stop displaying a screen of the wearable electronic device  301  and controlling the display of the content being displayed through the AR screen, based on a display area corresponding to the display module  160  of the electronic device  101 . 
     The performing control to display the content may include configuring a specified active window for the content being displayed on the AR screen through the default area and/or the extension area of the display module  160  of the electronic device  101 , and controlling display of content based on the configured active window. 
     The performing control to display the content may include, based on the determination of the second display mode, controlling display of content based on a virtual display area associated with the electronic device  101  on an AR screen provided through the display module  590  of the wearable electronic device  301 . 
     The performing control to display the content may include, based on the determination of the second display mode, configuring a virtual area corresponding to the extension area of the display module  160  of the electronic device  101  to correspond to the extension area of the electronic device  101 , configuring a specified active window for the content being displayed on the AR screen, based at least on the default area, the extension area, and/or the virtual area of the display module  160  of the electronic device  101 , and controlling display of the content through content mapping based on the configured active window. 
     If the content is provided according to the second display mode, the content mapped to the AR screen may be provided only through a display area associated with the electronic device  101  on the AR screen, instead of being displayed through the display module  160  of the electronic device  101  in the real space. 
     The method may further indicate determining whether or not the content corresponds to a specified profile when determining the target device processing the content and, if the content corresponds to the specified profile, determining the second display mode so as to provide content of the specified profile through the AR screen, regardless of the target device processing the content. 
     While the disclosure has been shown and described with reference to various embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure as defined by the appended claims and their equivalents.
