       FIG.  3    is an illustration for describing a function or operation of performing a specific function by a glasses-type wearable device based on a trigger event according to an embodiment of the disclosure. 
     Referring to  FIG.  3   , in operation  310 , the glasses-type wearable device  100  may control the display module  150  such that at least one graphical object (e.g., a first graphical object  410   a , a second graphical object  410   b , a third graphical object  410   c  and a fourth graphical object  420 ) is displayed in a display area  400 . 
       FIG.  4    is an illustration for describing at least one graphical object displayed by a glasses-type wearable device according to an embodiment of the disclosure. 
     Referring to  FIG.  4   , the display area  400  according to an embodiment of the disclosure may be an area configured such that at least one graphical object (e.g., the first graphical object  410   a , the second graphical object  410   b , the third graphical object  410   c , and the fourth graphical object  420 ) is displayed as a virtual object. According to an embodiment of the disclosure, the terms “field of view of the glasses-type wearable device 100” and/or “field of view of a display module” may be used as terms that implies the size of the display area  400  itself (e.g., the transverse and longitudinal lengths of the display area  400 , or the transverse and longitudinal angle ranges thereof (e.g., 50 degrees transversely and 30 degrees longitudinally) or the area of the display area  400  itself. In the display area  400  according to an embodiment of the disclosure, at least one graphical object (e.g., the first graphical object  410   a , the second graphical object  410   b , and the third graphical object  410   c ) corresponding to at least one counterpart device  280  operably connected to the glasses-type wearable device  100  may be displayed. The glasses-type wearable device  100  may be configured to receive information about the counterpart device  280  through a first network, a second network, and/or a server. The at least one graphical object (e.g., the first graphical object  410   a , the second graphical object  410   b , and the third graphical object  410   c ) may include, for example, a three-dimensional avatar (e.g., augmented reality (AR) Emoji) configured by a first user (e.g., a user using the glasses-type wearable device  100 ) or a second user (e.g., a user of the counterpart device  280 ), a video call execution screen, a voice call execution screen preconfigured by a call application, and/or a screen including a text message according to a format provided a message application or a specific application (e.g., an application for a conference). 
     Referring to 4, a state in which a specific session (e.g., a conference) is in progress through a specific application (e.g., an application for a conference) is illustrated.  FIG.  4    illustrates an embodiment in which the first graphical object  410   a  is displayed as a video call execution screen, the second graphical object  410   b  is displayed as a three-dimensional avatar configured by the counterpart device  280 , and the third graphical object  410   c  is displayed a screen including a text message according to a format provided by a specific application. The at least one graphical object (e.g., the first graphical object  410   a , the second graphical object  410   b , and the third graphical object  410   c ) corresponding to the at least one counterpart device  280 , according to an embodiment of the disclosure may be modified and displayed according to a display format provided by a device used by the second user. For example, when a counterpart device  280  corresponding to the first graphical object  410   a  is a smartphone including a two-dimensional flat type display, at least one graphical object (e.g., the second graphical object  410   b  and the third graphical object  410   c ) may be two-dimensionally displayed on the counterpart device  280  through a split screen (e.g., a multi-window screen). Furthermore, when the counterpart device  280  corresponding to the first graphical object  410   a  is a wearable device (e.g., the glasses-type wearable device  100 ), at least one graphical object (e.g., the second graphical object  410   b  and the third graphical object  410   c ) may be described, as illustrated in  FIG.  4   , as a virtual object in a three-dimensional space. Furthermore, according to an embodiment of the disclosure, even when the counterpart device  280  is a smartphone including a two-dimensional flat type display, at least one graphical object (e.g., the second graphical object  410   b  and the third graphical object  410   c ) may be displayed as a three-dimensional object. Furthermore, according to an embodiment of the disclosure, even when the counterpart device  280  is a wearable device (e.g., the glasses-type wearable device  100 ), at least one graphical object (e.g., the second graphical object  410   b  and the third graphical object  410   c ) may be displayed as a two-dimensional object. At least one graphical object (e.g., the fourth graphical object  420 ) may include an execution screen of a specific application (e.g., a video-providing application). 
     Referring to  FIG.  4   , an execution screen of one video-providing application the fourth graphical object  420  is illustrated, but an execution screen of multiple video-providing applications may be displayed as the fourth graphical object  420 , and an execution screen of different types of applications (e.g., a gallery application and a video-providing application) may be displayed as the fourth graphical object  420  in a display area  400 . According to an embodiment of the disclosure, a position and/or an order in which at least one graphical object (e.g., the first graphical object  410   a , the second graphical object  410   b , the third graphical object  410   c , and the fourth graphical object  420 ) is displayed in the display area  400  may be predesignated. For example, as illustrated in  FIG.  4   , the fourth graphical object  420  may be displayed at a substantial center of the display area  400 , and may be displayed counterclockwise from the upper left end of the display area  400  in the order in which the fourth graphical object  420  is connected to the glasses-type wearable device  100 . 
     In operation  320 , the glasses-type wearable device  100  may identify whether a first body part of a user (e.g., the first user) is positioned in a first area (e.g., a first area  510   a  or a first radius  510 ). The glasses-type wearable device  100  may compare a pre-stored template with an image acquired by the glasses-type wearable device  100  to identify the user’s body part. Alternatively, according to another embodiment of the disclosure, the user’s body part may be identified based on the result of learning according an artificial intelligence model. The artificial intelligence may include multiple artificial neural network layers. An artificial neural network may be one among a deep neural network (DNN), a convolutional neural network (CNN), a recurrent neural network (RNN), a restricted Boltzmann machine (RBM), a deep belief network (DBN), a bidirectional recurrent deep neural network (BRDNN), a deep Q-networks, or a combination of at least two thereof, but is not limited the above-mentioned examples. 
       FIG.  5 A  is an illustration for describing at least one radius configured to have an identical center with reference to a glasses-type wearable device according to an embodiment of the disclosure. 
       FIG.  5 B  is an illustration for describing at least one area configured in a display area as a method for determining whether a first body part of a user is positioned within at least one radius area according to an embodiment of the disclosure. 
     Referring to  FIG.  5 A , the at least one radius area (e.g., a first radius area  510 , a second radius area  520 , and a third radius area  530 ) according to an embodiment of the disclosure may imply a two-dimensional area or a three-dimensional area configured to have a specific angle with respect to a first body part of a user (e.g., the right hand of the user). Furthermore, according to another embodiment of the disclosure, the at least one radius area (e.g., the first radius area  510 , the second radius area  520 , and the third radius area  530 ) may imply a two-dimensional area or a three-dimensional area that is divided into multiple areas with reference to the field of view of a display module  160 . Although not illustrated, at least one radius area (e.g., the first radius area  510  and the second radius area  520 ) may be configured to have different centers (e.g., a right hand and a left hand), respectively. In other words, the center of at least one radius area (e.g., the first radius area  510  and the second radius area  520 ) may be changed depending on whether the first body part of the user is the right hand or the left hand. According to an embodiment of the disclosure, in order to for the glasses-type wearable device  100  to identify whether the first body part (e.g., the right hand) of the user is positioned in a first area (e.g., the first area  510   a  or the first radius area  510 ), at least one area (e.g., the first area  510   a , a second area  520   a , a third area  530   a ) may be preconfigured with respect to the display area  400 , referring to  FIG.  5 B . According to an embodiment of the disclosure, the size, area, or the number of at least one area (e.g., the first area  510   a , the second area  520   a , or the third area  530   a ) may be changed by the user’s configuration. According to an embodiment of the disclosure, the at least one area (e.g., the first area  510   a , the second area  520   a , or the third area  530   a ) may be determined based on a position and/or a number in which at least one graphical object (e.g., the first graphical object  410   a , the second graphical object  410   b , the third graphical object  410   c , and the fourth graphical object  420 ) are displayed. For example, when more graphical objects are displayed on the right side than on the left side with reference to the user’s position, the area of at least one area (e.g., the first area  510   a , the second area  520   a , or the third area  530   a ) may be configured such that a radius area (e.g., the third radius area  530 ) configured at the right side with reference to the user covers a larger area than other radius areas. 
     The at least one area (e.g., the first area  510   a , the second area  520   a , or the third area  530   a ) may be configured based on coordinate values of the display area  400 . For example, when the abscissa value of the display area  400  is configured to have a value of 0 to  1000 , a range of 0-200 may be designated as the first area  510   a , a range from greater than 200 to 800 may be designated as a second area  520   a , and a range from greater than 800 to  1000  may be designated as a third area  530   c . The above-mentioned designated at least one area (e.g., the first area  510   a , the second area  520   a , or the third area  530   a ) may correspond to the at least one radius area (e.g., the first radius area  510 , the second radius area  520 , and the third radius area  530 ). 
       FIG.  5 C  is an illustration for describing a function or operation in which a glasses-type wearable device determines that a first body part of a user is positioned in a first radius area when it is detected that the first body part of the user is positioned in a first area according to an embodiment of the disclosure. 
     Referring to  FIG.  5 C , when it is detected that the first body part (e.g., the right hand) of the user is positioned in the first area  510   a , the glasses-type wearable device  100  may identify that the first body part of the user is positioned in the first radius area  510 . When it is detected that the user’s body part is positioned with a predetermined threshold area or larger in a specific area (e.g., the first area  510   a ), the glasses-type wearable device  100  may detect that the user’s body part is positioned in the specific area (e.g., the first area  510   a ). For example, when the user’s body part (e.g., the right hand) is over the second area  520   a  and the third area  530   a , the glasses-type wearable device  100  according to an embodiment of the disclosure may detect (e.g., determine) that the user’s body part is positioned in an area including a larger area of the user’s body part. The wearable device  100  according to an embodiment of the disclosure may identify the first body part of the user by using at least one camera (e.g., the first camera  111 ). 
       FIGS.  5 D and  5 E  are illustrations for describing a function or operation in which a glasses-type wearable device determines that a first body part of a user is positioned in a first radius area when it is detected that the first body part of the user is positioned in a space configured with reference to a first area according to various embodiments of the disclosure. 
     Referring to  FIGS.  5 D and  5 E , according to another embodiment of the disclosure, when it is detected that a first body part of a user is positioned in a space (e.g., a first space  512 ) configured in advance or based on the user’s configuration with reference to the first area  510   a , the wearable device  100  may identify that the first body part of the user is positioned in at least one radius area (e.g., the first radius area  510 ). In this case, as illustrated in  FIG.  5 E , even when the first body part of the user is not included in the display area  400 , the glasses-type wearable device  100  may identify that the first body part of the user is positioned in the first radius area  510 . 
       FIG.  5 F  is an illustration for describing a case in which at least one radius area is configured according to an embodiment of the disclosure. 
       FIGS.  5 G and  5 H  are illustrations for describing a function or operation in which, when at least one radius is configured, a glasses-type wearable device detects that a first body part of a user is positioned within the at least one radius area according to various embodiments of the disclosure. 
     Referring to  FIG.  5 F , radius areas (e.g., the first radius area  510 , the second radius area  520 , and the third radius area  530 ) according to an embodiment of the disclosure may be configured to be away from the user (e.g., in a horizontal direction with reference to the user’s position). In this case, the glasses-type wearable device  100  according to an embodiment of the disclosure may determine, based on the distance by which a second body part of the user (e.g., an elbow or a part at which an arm is folded in the opposite direction to the elbow) is spaced apart from the glasses-type wearable device  100 , whether the first body part (e.g., the right hand) of the user is positioned in a specific radius area (e.g., the first radius area  510 , the second radius area  520 , or the third radius area  530 ). In other words, the glasses-type wearable device  100  according to an embodiment of the disclosure may select different radius areas depending on the extent to which the user’s arm is extended (e.g., the length of an arm). For example, the glasses-type wearable device  100  according to an embodiment of the disclosure may determine that the first body part (e.g., the right hand) of the user is included in the first radius area  510  within a range where the second body part (e.g., the elbow) of the user is not visible. Accordingly, referring to  FIG.  5 G , the glasses-type wearable device  100  may identify that the user’s body part (e.g., right hand) is included in the first radius area  510 . When the user’s body part is detected within a predetermined distance by which the elbow is moved from a position in which the second body part (e.g., the elbow) of the user starts to be detected, the glasses-type wearable device  100  according to an embodiment of the disclosure may determine that the user’s body part (e.g., the right hand) is included in the second radius area  520 . Accordingly, referring to  FIG.  5 H , the glasses-type wearable device  100  may identify that the first body part (e.g., the right hand) of the user is included in the second radius area  520 . The first body part (e.g., e.g., a body part that is a reference for identifying that the user’s body part is included in a radius area) of the user and the second body part (e.g., a body part that is a reference for determining a radius area in which the user’s body part is included) of the user, according to an embodiment of the disclosure, may be predesignated. 
       FIG.  5 I  is an illustration for describing a case in which at least one radius is configured according to an embodiment of the disclosure. 
     Referring to  FIG.  5 I , the radius areas (e.g., the first radius area  510  and the second radius area  520 ) may be configured based on different centers. Even in this case, specific areas (e.g., the first area  510   a  and the second area  520   a ) of the display area  400  corresponding to the radius areas (e.g., the first radius area  510  and the second radius area  520 ) may be preconfigured. Furthermore, a shading effect for indicating that a specific area has been selected, illustrated in  FIGS.  5 G and  5 H , may not be shown to the user. 
     In operation  330 , the glasses-type wearable device  100  may identify a group corresponding to the first area (e.g., the first area  510   a ), based on a fact that the user’ body part (e.g., the right hand) is positioned in the first area (e.g., the first area  510   a ). 
       FIGS.  6 A and  6 B  are illustrations for describing a group preconfigured to correspond to at least one radius according to various embodiments of the disclosure. 
     Referring to  FIG.  6 A , the glasses-type wearable device  100  may identify that the counterpart device  280  corresponding to the first graphical object  410   a  and the counterpart device  280  corresponding to the second graphical object  410   b  belong to the same group. The group may be configured to correspond to at least one radius area (e.g., the first radius area  510 , the second radius area  520  and/or the third radius area  530 ).  FIG.  6 A  illustrates an embodiment in which the counterpart device  280  corresponding to the first graphical object  410   a  and a counterpart device corresponding to the second graphical object  410   b  is configured by the user in advance (e.g., before execution of a conference application) to belong to the same group. When it is detected that the first body part (e.g., the right hand) of the user is positioned in the first radius area  510 , the glasses-type wearable device  100  may display a visual effect (e.g., an edge) around at least one graphical object (e.g., the first graphical object  410   a  and the second graphical object  410   b ) belonging to a first group configured to correspond to the first radius area  510 . However, the glasses-type wearable device  100  may provide an auditory effect (e.g., a predesignated sound) and/or a tactile effect (e.g., a vibration having a predesignated intensity) through the glasses-type wearable device  100 .  FIG.  6 A  illustrate an example in which the first graphical object  410   a  and the second graphical object  410   b  are configured as one group corresponding to the first radius area  510 , and  FIG.  6 B  illustrates an example in which the first graphical object  410   a  is configured as one group corresponding to the first radius area  510 . 
     In operation  340 , the glasses-type wearable device  100  may identify whether a trigger event is detected while the first body part of the user is positioned in the first area (e.g., the first radius area  510 ). The trigger event may include detection a predesignated gesture (e.g., a trigger gesture) by the first body part (e.g., the right hand) of the user or detection of a voice command of the user. According to an embodiment of the disclosure, when the trigger event includes detection of a voice command, the first body part of the user may be positioned in the first state. However, according to another embodiment of the disclosure, the first body part of the user may not be positioned in the first area. 
       FIGS.  7 A and  7 B  are illustrations for describing a trigger gesture according to various embodiments of the disclosure. 
     Referring to  FIG.  7 A , a heart gesture is illustrated as an example of a trigger gesture. 
     Referring to  FIG.  7 B , a gesture of moving a hand up and down with a raised thumb is illustrated as an example of a trigger gesture. According to another embodiment of the disclosure, the trigger event may include an event that detects a change in the facial expression of the user and/or the movement of the user’s pupils. The glasses-type wearable device  100  may detect a change in the facial expression of the user and the movement of the user pupils by using an image of the user’s face acquired through at least one camera (e.g., the second camera  112 ). 
     In operation  350 , the glasses-type wearable device  100  according to an embodiment of the disclosure may perform, based on detection of the trigger event, a function corresponding to the trigger event with respect to the counterpart device  280  included in the identified group. 
       FIG.  8    is an illustration for describing a function or operation in which a specific function is performed by the glasses-type wearable device  100  based on a trigger event (e.g., detection of a trigger gesture) according to an embodiment of the disclosure. 
     Referring to  FIG.  8   , it illustrates an embodiment in which, when a trigger gesture is detected, a glasses-type wearable device according to an embodiment of the disclosure performs a function (e.g., transmission of a message including a heart) corresponding to the detected trigger event (e.g., the heart gesture) with respect to the counterpart device  280  belonging to a specific group. The message corresponding to the trigger event according to an embodiment of the disclosure may be displayed (e.g., two-dimensionally displayed) on a video call execution screen when a counterpart device is present at a corresponding session (e.g., a conference) through a video call using a smartphone. Alternatively, referring to  FIG.  8   , the message corresponding to the trigger event according to an embodiment of the disclosure may be displayed (e.g., three-dimensionally displayed) in the form of an emoticon  810  on a chatting window provided by a specific application. Alternatively, the message corresponding to the trigger event according to an embodiment of the disclosure may be transmitted as a short message service (SMS) message to the counterpart device  280 . When describing with reference to  FIG.  8   , the message corresponding to the trigger event according to an embodiment of the disclosure may be transmitted to all counterpart devices  280  (e.g., a counterpart device corresponding to the first graphical object  410   a  and a counterpart device corresponding to the second graphical object  410   b ) of included in a group corresponding to the first radius area  510 . In order to transmit the message corresponding to the trigger gesture to the counterpart device  280 , the glasses-type wearable device  100  according to an embodiment of the disclosure may perform a function or operation of identifying the counterpart device  280  belonging to a specific group. According to an embodiment of the disclosure, after a visual effect  610  is displayed, the display state of the visual effect  610  may be maintained even when the user positions the first body part outside the first area (e.g., the first radius area  510 ), and a specific function based on the detection of the trigger event may be performed for all counterpart devices  280  (e.g., a counterpart device corresponding to the first graphical object  410   a  and a counterpart device corresponding to the second graphical object  410   b ) included in a group corresponding to the first area (e.g., the first radius area  510 ). Alternatively, after the visual effect  610  is displayed, when the user positions the first body part outside the first area (e.g., the first radius area  510 ), the visual effect  610  may no longer be displayed, and the specific function may be controlled not to be performed by the glasses-type wearable device  100  even when a trigger event is detected (e.g., detection of a heart gesture). According to another embodiment of the disclosure, when it is detected that the user’s pupils move a predesignated distance or more or that the facial expression of the user is changed from a first state to a second state, the glasses-type wearable device  100  may perform a specific function. According to an embodiment of the disclosure, the glasses-type wearable device  100  may use a template for a facial expression, stored in the memory  140 , to detect a change in the facial expression of the user. The glasses-type wearable device  100  may compare the template with a facial expression of the user in the acquired image, and when a matching ratio is equal to or greater than a predesignated ratio, may determine that the facial expression of the user is in a specific state (e.g., a smiling state). Alternatively, a function or operation of determining the facial expression of the user may be learned by an artificial intelligence model. 
       FIG.  9    is an illustration for describing a function or operation of performing, by a glasses-type wearable device, communication with (e.g., transmission of a text message to) at least one counterpart device, based on reception of a communication signal from an external electronic device operably connected to the glasses-type wearable device according to an embodiment of the disclosure. 
     Referring to  FIG.  9   , in operation  910 , the glasses-type wearable device  100  may control the display module  150  such that at least one graphical object (e.g., the first graphical object  410   a , the second graphical object  410   b , the third graphical object  410   c , and the fourth graphical object  420 ) is displayed on the display area  400 . In operation  920 , the glasses-type wearable device  100  may identify whether a first body part of a user (e.g., the first user) is positioned in a first area (e.g., the first area  510   a  or the first radius  510 ). In operation  930 , the glasses-type wearable device  100  may identify a group corresponding to the first area (e.g., the first area  510   a ), based on a fact that the user’s body part (e.g., the right hand) is positioned in the first area (e.g., the first area  510   a ). The above description of operations  310  to  330  may be applied to operations  910  to  930  according to an embodiment of the disclosure, and thus the detailed description thereof will be omitted. 
     In operation  940 , the glasses-type wearable device  100  according to an embodiment of the disclosure may receive, from an external electronic device (e.g., a smartphone)  1000 , a request for communicating with the counterpart device  280  belonging to the identified group (e.g., the first graphical object  410   a  and the third graphical object  410   c ) (e.g., transmitting a text message input in the smartphone). In operation  950 , the glasses-type wearable device  100  according to an embodiment of the disclosure may communicate with a counterpart device, based on the received request. 
       FIGS.  10 A,  10 B, and  10 C  are illustrations for describing a function or operation described in  FIG.  9    in terms of view of a graphical user interface according to various embodiments of the disclosure. 
     Referring to  FIGS.  10 A,  10 B, and  10 C , an external electronic device (e.g., a smartphone) according to an embodiment of the disclosure may be operably connected to the glasses-type wearable device  100  through wired communication or wireless communication. Referring to  FIG.  10 B , when a signal indicating that a “send” button  1020  of the external electronic device has been selected is received from the external electronic device (e.g., the smartphone), the glasses-type wearable device  100  according to an embodiment of the disclosure may receive information about text input from the external electronic device and may transmit a text message to the counterpart device  280  belonging to the identified group (e.g., the first graphical object  410   a  and the third graphical object  410   c ). Referring to  FIG.  10 C , after the text message is transmitted, a transmitted text  1030  may be displayed on an execution screen  1010  of an application (e.g., a text message application). According to another embodiment of the disclosure, when a signal indicating that the “send” button  1020  of the external electronic device  1000  has been selected as illustrated in  FIG.  10 B  is received from the external electronic device (e.g., the smartphone), the external electronic device  1000  may be controlled such that a text message including input text (e.g., Hello) is transmitted to the identified counterpart device  280 . According to an embodiment of the disclosure, while operation  940  and operation  950  are performed, the position of the first body part (e.g., the right hand) of the user may not be maintained in the first area (e.g., the first radius area  510 ). Referring to  FIG.  10 A ,  FIGS.  10 B and  10 C  illustrate embodiments in which the position of the first body part (e.g., the right hand) of the user is not maintained in the first area (e.g., the first radius area  510 ) after a specific group is detected based on the detection of the first body part (e.g., the right hand) of the user. However, according to another embodiment of the disclosure, operations  940  and  950  may performed only when the position of the first body part (e.g., the right hand) of the user is maintained in the first area (e.g., the first radius area  510 ) from a time at which operation  930  is performed. 
       FIG.  11    is an illustration for describing a function or operation in which a glasses-type wearable device shares at least one content with at least one counterpart device when a sharing gesture is detected according to an embodiment of the disclosure.

     Referring to  FIG.  11   , in operation  1110 , the glasses-type wearable device  100  may receive a request for sharing at least one content (e.g., the fifth content  1225 ). According to an embodiment of the disclosure, the request for sharing the at least one content (e.g., the fifth content  1225 ) may include a virtual touch input  1210  for one item (e.g., a second item  1214 ) among, for example, multiple items (e.g., a first item  1212 , the second item  1214 , and a third item  1216 ) displayed in the display area  400 . When it is determined that an image of a user’s body part (e.g., the right hand), acquired by using at least one camera (e.g., the first camera  111 ), overlap one item (e.g., the second item  1214 ) among the multiple items (e.g., the first item  1212 , the second item  1214 , and the third item  1216 ), or when the movement of a finger selecting the one item (e.g., the second item  1214 ) in the overlapping state is detected, the glasses-type wearable device may determine that a virtual touch input for the one item (e.g., the second item  1214 ) has been received. According to another embodiment of the disclosure, whether a virtual touch has been input may be determined by a separate device (e.g., a sensor provided in the user’s hand) for determining virtual touches. According to another embodiment of the disclosure, multiple cameras may be used to recognize coordinates in a space in which the user’s fingertip is positioned, and whether a virtual touch has been input may be determined based on whether the recognized coordinates in the space match coordinates in a space in which the one item (e.g., the second item  1214 ) is displayed. In addition, various algorithms (e.g., an artificial intelligence model algorithm) for determining that a virtual touch has been performed may be applied. 
     In operation  1120 , the glasses-type wearable device  100  may receive a selection input (e.g., a virtual touch input) for the at least one content (e.g., the fifth content  1225 ). When the request for sharing the at least one content (e.g., the fifth content  1225 ) is received in operation  1110 , the glasses-type wearable device  100  may display, in the display area  400 , multiple contents to be shared.

The glasses-type wearable device  100  may receive (e.g., identify) a virtual touch input for one image (e.g., the fifth content  1225 ) among the multiple images (e.g., the first content  1221 , the second content  1222 , the third content  1223 , the fourth content  1224 , the fifth content  1225 , and the sixth content  1226 ). However, the virtual touch input is an embodiment of the selection input, and operation  1120  may be performed by various devices (e.g., a touch panel or a sensor included in the glasses-type wearable device  100 ). 
     In operation  1130 , the glasses-type wearable device  100  may identify a graphical object corresponding to a group configured for an area (e.g., the first radius area  510 ) in which the user’s body part is positioned. Referring to  FIG.  12 C , the glasses-type wearable device  100  may detect a gesture (e.g., a virtual drag gesture) for moving the selected content (e.g., the fifth content  1225 ) to a specific area (e.g., the first radius area  510 ). In this case, as illustrated in  FIG.  12 C , the selected content (e.g., the fifth content  1225 ) may be displayed as a thumbnail image in the display area  400  until the user’s gesture ends.  FIG.  12 C  illustrates an embodiment in which the first graphical object  410   a  and the second graphical object  410   b  are determined as graphical objects corresponding to the first area (e.g., the first radius area  510 ). When it is detected that the user’s body part entered the first area (e.g., the first radius area  510 ), the glasses-type wearable device  100  may display the visual effect  610  around the first graphical object  410   a  and the second graphical object  410   b . 
     In operation  1140 , the glasses-type wearable device  100  according to an embodiment herein may detect a sharing gesture. In operation  1150 , the glasses-type wearable device  100  may transmit, based on the detection of the sharing gesture, at least one content (e.g., the fifth content  1225 ) to the counterpart device  280   corresponding to the identified graphical object. The sharing gesture may include a virtual drop gesture for dropping the displayed thumbnail image. In order to determine the gesture for dropping the thumbnail image, the glasses-type wearable device  100  may use at least some of the above-mentioned functions or operations of determining the virtual touch input or a template (e.g., a template corresponding to the drop gesture) pre-stored in the glasses-type wearable device  100  to determine whether the user’s gesture is a gesture for dropping the thumbnail image. When the sharing gesture is detected, the glasses-type wearable device  100  may transmit data about at least one content (e.g., the fifth content) stored in the glasses-type wearable device  100  to counterpart devices  280  (e.g., the counterpart device  280  corresponding to the first graphical object  410   a  and the counterpart device  280  corresponding to the second graphical object  410   b ).

As used herein, each of such phrases as “A or B”, “at least one of A and B”, “at least one of A or B”, “A, B, or C”, “at least one of A, B, and C”, and “at least one of A, B, or C”, may include any one of, or all possible combinations of the items enumerated together in a corresponding one of the phrases. As used herein, such terms as “1st” and “2nd”, or “first” and “second” may be used to simply distinguish a corresponding component from another, and does not limit the components in other aspect (e.g., importance or order). It is to be understood that if an element (e.g., a first element) is referred to, with or without the term “operatively” or “communicatively”, as “coupled with”, “coupled to”, “connected with”, or “connected to” another element (e.g., a second element), it means that the element may be coupled with the other element directly (e.g., wiredly), wirelessly, or via a third element. 
     As used in connection with various embodiments of the disclosure, the term “module” may include a unit implemented in hardware, software, or firmware, and may interchangeably be used with other terms, for example, “logic”, “logic block”, “part”, or “circuitry”. A module may be a single integral component, or a minimum unit or part thereof, adapted to perform one or more functions. For example, according to an embodiment of the disclosure, the module may be implemented in a form of an application-specific integrated circuit (ASIC). 
     Various embodiments as set forth herein may be implemented as software (e.g., the program  1540 ) including one or more instructions that are stored in a storage medium (e.g., an internal memory  1536  or an external memory  1538 ) that is readable by a machine (e.g., the electronic device  1501 ). For example, a processor (e.g., the processor  1520 ) of the machine (e.g., the electronic device  1501 ) may invoke at least one of the one or more instructions stored in the storage medium, and execute it. This allows the machine to be operated to perform at least one function according to the at least one instruction invoked. The one or more instructions may include a code generated by a complier or a code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Wherein, the term “non-transitory” simply means that the storage medium is a tangible device, and does not include a signal (e.g., an electromagnetic wave), but this term does not differentiate between where data is semi-permanently stored in the storage medium and where the data is temporarily stored in the storage medium. 
     According to an embodiment of the disclosure, a method according to various embodiments of the disclosure may be included and provided in a computer program product. The computer program product may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., a compact disc read only memory (CD-ROM)), or be distributed (e.g., downloaded or uploaded) online via an application store (e.g., PlayStore™), or between two user devices (e.g., smart phones) directly. If distributed online, at least part of the computer program product may be temporarily generated or at least temporarily stored in the machine-readable storage medium, such as memory of the manufacturer’s server, a server of the application store, or a relay server.
