With regard to description of drawings, similar elements may be marked by similar reference numerals. 
         [0043]    In the disclosure disclosed herein, the expressions “have”, “may have”, “include” and “comprise”, or “may include” and “may comprise” used herein indicate existence of corresponding features (e.g., elements such as numeric values, functions, operations, or components) but do not exclude presence of additional features. 
         [0044]    In the disclosure disclosed herein, the expressions “A or B”, “at least one of A or/and B”, or “one or more of A or/and B”, and the like used herein may include any and all combinations of one or more of the associated listed items. For example, the term “A or B”, “at least one of A and B”, or “at least one of A or B” may refer to all of the case (1) where at least one A is included, the case (2) where at least one B is included, or the case (3) where both of at least one A and at least one B are included. 
         [0045]    The terms, such as “first”, “second”, and the like used herein may refer to various elements of various embodiments, but do not limit the elements. Furthermore, such terms may be used to distinguish one element from another element. For example, “a first user device” and “a second user device” may indicate different user devices regardless of the order or priority thereof.

At least part of the kernel  141 , the middleware  143 , or the API  145  may be referred to as an operating system (OS). 
         [0058]    The kernel  141  may control or manage, for example, system resources (e.g., the bus  110 , the processor  120 , or the memory  130 , and the like) used to execute an operation or function implemented in the other programs (e.g., the middleware  143 , the API  145 , or the application program  147 ). Also, as the middleware  143 , the API  145 , or the application program  147  accesses a separate component of the electronic device  100 , the kernel  141  may provide an interface which may control or manage system resources. 
         [0059]    The middleware  143  may play a role as, for example, a go-between such that the API  145  or the application program  147  communicates with the kernel  141  to communicate data. 
         [0060]    Also, the middleware  143  may process one or more work requests, received from the application program  147 , in order of priority. For example, the middleware  143  may assign priority which may use system resources (the bus  110 , the processor  120 , or the memory  130 , and the like) of the electronic device  100  to at least one of the at least one application program  147 . For example, the middleware  143  may perform scheduling or load balancing for the one or more work requests by processing the one or more work requests in order of priority assigned to the at least one of the at least one application program  147 . 
         [0061]    The API  145  may be, for example, an interface in which the application program  147  controls a function provided from the kernel  141  or the middleware  143 . For example, the API  145  may include at least one interface or function (e.g., instruction) for file control, window control, image processing, or text control, and the like. 
         [0062]    The I/O interface  150  may play a role as, for example, an interface which may transmit instructions or data, input from a user or another external device, to another component (or other components) of the electronic device  100 . Also, the I/O interface  150  may output instructions or data, received from another component (or other components) of the electronic device  100 , to the user or the other external device. 
         [0063]    The display circuit  160  may include, for example, a liquid crystal display (LCD), a light emitting diode (LED) display, an organic LED (OLED) display, a microelectromechanical systems (MEMS) display, or an electronic paper display. The display circuit  160  may display, for example, a variety of content (e.g., text, an image, a video, an icon, or a symbol, and the like) to the user. The display circuit  160  may include a touch screen, and may receive, for example, a touch, a gesture, proximity, or a hovering input using an electronic pen or part of a body of the user. 
         [0064]    The communication circuit  170  may establish communication between, for example, the electronic device  100  and an external device (e.g., a first external electronic device  102 , a second external electronic device  104 , or a server  106 ). For example, the communication circuit  170  may connect to a network  162  through wireless communication or wired communication and may communicate with the external device (e.g., the second external electronic device  104  or the server  106 ). 
         [0065]    The wireless communication may use, for example, at least one of long term evolution (LTE), LTE-advanced (LTE-A), code division multiple access (CDMA), wideband CDMA (WCDMA), universal mobile telecommunications system (UMTS), wireless broadband (WiBro), or global system for mobile communications (GSM), and the like as a cellular communication protocol.

         [0102]      FIG. 4  illustrates a block diagram of a configuration of an electronic device  400  for providing a one-handed UI according to various embodiments of the present disclosure. Referring to  FIG. 4 , the electronic device  400  may include a display circuit  410 , a user input circuit  420 , a processor  430 , and a memory  440 . The configuration of the electronic device  400  is only one implementation example of the present disclosure, and several modifications are possible. For example, the electronic device  400  may further include a user interface (UI) for receiving any instructions or information from its user. In this example, the UI may generally be an input device such as a keyboard and a mouse. Alternatively, the UI may be a graphical user interface (GUI) displayed on a screen (not shown) of the electronic device  400 . 
         [0103]    The display circuit  410  may display a variety of content (e.g., an application execution screen, text, an image, a video, an icon, or a symbol, and the like) on an screen of the electronic device  400 . The screen may include, for example, a liquid crystal display (LCD), a light emitting diode (LED) display, an organic LED (OLED) display, a microelectromechanical systems (MEMS) display, or an electronic paper display, and the like. 
         [0104]    The user input circuit  420  may process a user input received from the user. The user input may be a touch input using a finger or a stylus (e.g., an electronic pen) of the user. Also, the user input may include a non-contact input, for example, a hover input, which may be provided through an electric change, although the finger or stylus of the user is not in direct contact with the screen. According to various embodiments of the present disclosure, the user input circuit  420  may be a touch integrated circuit (IC). 
         [0105]    In this example, the user input circuit  420  (e.g., a touch circuit IC) may distinguish various types of touch inputs to process the touch inputs. The user inputs may include, for example, touch-down, touch drag (or touch move), touch release, touch hold (or long press), and touch and drop, and the like. 
         [0106]    According to various embodiments of the present disclosure, although not illustrated in  FIG. 4 , the user input circuit  420  may receive a user input using various sensors (e.g., at least one or more sensors included in a sensor circuit  240  of  FIG. 2 ) included in the electronic device  400 . For example, the user input circuit  420  may receive a touch input of the user, an electronic pen input, or a hover input using a touch sensor. 
         [0107]    Also, the user input may include a direction change of the electronic device  400 . The electronic device  400  may determine whether its direction is changed using a gyro sensor and the like. The processor  430  may activate a transverse mode or a longitudinal mode based on a direction change of the electronic device  400 . 
         [0108]    The processor  430  may be implemented with, for example, a system on chip (SoC) and may include one or more of a central processing unit (CPU), a graphic processing unit (GPU), an image signal processor, an application processor (AP), or a communication processor (CP). The processor  430  may load instructions or data, received from at least one of the other components (e.g., the display circuit  410 , the user input circuit  420 , and the at least one or more sensors), into the memory  440  to process the instructions and data and may store a variety of data in the memory  440 . 
         [0109]    The processor  430  may display at least one or more objects on a screen via the display circuit  410 . The object may include a control object and a content icon. The control object may be an object provided for convenience of the user on a one-handed UI. For example, the user may select an application icon which is too distant to be touched with his or her hand which holds the electronic device  400  using the control object. 
         [0110]    According to various embodiments of the present disclosure, a location where the control object is displayed may be determined in consideration of a holding location of the user who holds the electronic device  400 . For example, the processor  430  may display the control object on a location with which a thumb of a holding hand is in natural contact, in a state where the user holds the electronic device  400 . According to various embodiments of the present disclosure, the location with which the thumb of the user is in natural contact may be determined through a user setting and may be determined by analyzing touch input history of the user. 
         [0111]    The content icon may include, for example, an application icon, a folder icon, a favorites icon, a shortcut icon, a widget icon, and the like. 
         [0112]    The processor  430  may receive a series of user inputs including touch-down, touch drag, and touch release on the control object via the user input circuit  420 . 
         [0113]    The processor  430  may receive touch-down on the control object via the user input circuit  420 . The touch-down may refer to a user input which is input by an operation where the user is in contact with the screen with his or her finger. The processor  430  may display a pointer (or pointer image, or pointer object) on the display circuit  410  in response to the input touch-down. The pointer is to select an object for providing an execution command, for example, may correspond to a mouse pointer of a personal computer (PC). 
         [0114]    Also, the processor  430  may display a function object on the display circuit  410  in response to the input touch-down. The function object may correspond to a hardware button. The hardware button may include a touch button, a home button, a volume button, a power button, and the like which are located in a housing of the electronic device  400 . Also, the function object may be implemented to execute an operation which may not be input while the user holds the electronic device  400  through the function object. For example, the function object may be an object which may perform an operation of unfolding a quick-panel. 
         [0115]    According to various embodiments of the present disclosure, the processor  430  may reduce brightness of a screen displayed on the screen in response to the input touch-down. 
         [0116]    The processor  430  may receive touch drag in a state where touch-down on the control object occurs, via the user input circuit  420 . The touch drag may refer to, for example, a user input which is input by an operation where a finger of the user moves on the screen while the finger is in contact with the screen. In this example, the processor  430  may move the control object and the pointer via the display circuit  410 . According to various embodiments of the present disclosure, a movement distance of the control object may be different from a movement distance of the pointer. For example, the movement distance of the pointer may be longer than that of the control object. This is because a distance where the control object may be moved with a hand holding the electronic device  400  is limited (e.g., because a touch enable distance is limited if an operation of touching a control object displayed on a display using a thumb of a holding hand after the user holds the electronic device  400  with his or her both hands or one hand), but the pointer should be able to move on the entire region of the screen based on motion of the control object. The processor  430  may determine a value, in which some multiples are applied to a movement distance of the control object, as a movement distance of the pointer. 
         [0117]    The processor  430  may stop touch drag on the control object and may receive touch release via the user input circuit  420 . The touch release may refer to, for example, a user input which is input by an operation where the user takes his or her finger off the screen. The processor  430  may execute an operation corresponding to a location of the pointer at a time of the touch release. For example, if the pointer is on an application icon, the processor  430  may execute an application corresponding to the pointer. If the pointer is on a folder icon, the processor  430  may unfold a corresponding folder and may display detailed items. 
         [0118]    According to various embodiments of the present disclosure, if the pointer is on a region where a content icon is not displayed (e.g., a region where only a background screen is displayed between a content icon and a content icon), the processor  430  may not execute any operation. Also, if the pointer departs from a screen displayed on the screen at a time of touch release on the control object, the processor  430  may not execute any operation. 
         [0119]    According to various embodiments of the present disclosure, the touch release on the object may be performed together with touch hold. The touch hold may refer to, for example, an operation of stopping for periods of time while the user is in contact with the screen with his or her finger. If touch release including the touch hold is received via the user input circuit  420 , the processor  430  may execute an operation corresponding to a location of the pointer at a time of the touch hold on the object. For example, if the pointer is on a content icon, the processor  430  may activate a mode of moving a location of the content icon or deleting the content icon. If the pointer is located on a region where a content icon is not displayed (e.g., a region where only a background screen is displayed between a content icon and a content icon), the processor  430  may display a menu. 
         [0120]    If the control object is adjacent to the function object through the touch drag, the processor  430  may activate the function object. For example, if touch release on the control object is received on a location of the control object, the activation of the function object may indicate that the function object is ready to execute. Also, the processor  430  may indicate that the processor  430  is ready to execute the function object, via an indicator (e.g., an indicator displayed on an indicator region displayed on an upper end of a display). For example, the processor  430  may display the function object to be larger in size than a previous display state or may turn on/off the function object. 
         [0121]    According to various embodiments of the present disclosure, the processor  430  may not display the function object in a situation where touch-down on the control object is received. If the control object or the pointer is adjacent to a specified location (e.g., a location where the function object will be displayed) based on a touch drag input on the control object, the processor  430  may display the function object. 
         [0122]    After the touch release, the processor  430  may display the control object again on a location before the user input. Herein, according to various embodiments of the present disclosure, if touch release on the control object is performed after the control object is moved to a vertical axis by a half or more of the screen, the processor  430  may change a location of the control object and may display the changed control object. The operation of changing the location of the control object and displaying the changed control object may be an operation of changing a left-handed mode and a right-handed mode. For example, after the control object is moved to a right region of the screen in a state where the control object is displayed on a left region of the screen, if touch release on the control object occurs, the processor  430  may change the left-handed mode to the right-handed mode. Alternatively, the right-handed mode may be changed to the left-handed mode. 
         [0123]    According to various embodiments of the present disclosure, the processor  430  may vary a function object displayed based on the left-handed mode and the right-handed mode. For example, the processor  430  may display a function object, corresponding to a hardware button located at the right of the electronic device  400 , on a left region of the electronic device  400  in the left-handed mode. Similarly, the processor  430  may display a function object, corresponding to a hardware button located at the left of the electronic device  400 , on a right region of the electronic device  400  in the right-handed mode. 
         [0124]    According to various embodiments of the present disclosure, the processor  430  may vary a location of the function object in a transverse mode and a longitudinal mode of the electronic device  400 . Also, the processor  430  may determine a location of a control object and a location of a pointer in a different way based on each of the transverse mode and the longitudinal mode. 
         [0125]    The memory  440  may store data, for example, instructions for operations performed in the processor  430 . In this example, the data stored in the memory  440  may include data input and output between components included in the electronic device  400  and data input and output between the electronic device  400  and components outside the electronic device  400 . 
         [0126]    This memory  440  may include an embedded memory or an external memory. The embedded memory may include at least one of, for example, a volatile memory (e.g., a dynamic random access memory (DRAM), a static RAM (SRAM), a synchronous dynamic RAM (SDRAM), and the like), or a non-volatile memory (e.g., a one-time programmable read only memory (OTPROM), a programmable ROM (PROM), an erasable and programmable ROM (EPROM), an electrically erasable and programmable ROM (EEPROM), a mask ROM, a flash ROM, a flash memory (e.g., a NAND flash memory or a NOR flash memory, and the like), a hard drive, or a solid state drive (SSD)). 
         [0127]    The external memory may include a flash drive, for example, a compact flash (CF), a secure digital (SD), a micro-SD, a mini-SD, an extreme digital (xD), a multimedia car (MMC), or a memory stick, and the like. The external memory may operatively and/or physically connect with the electronic device  400  through various interfaces. 
         [0128]    It should be well understood to those skilled in the art that each of the display circuit  410 , the user input circuit  420 , the processor  430 , and the memory  440  may be implemented to be independent of the electronic device  400  or one or more thereof may be implemented to be integrated into one in the electronic device  400 . 
         [0129]      FIG. 5  illustrates a drawing of a basic state of a one-handed UI  500  according to various embodiments of the present disclosure. 
         [0130]    Referring to  FIG. 5 , a control object  510  may be displayed on the one-handed UI  500 . The basic state may refer to a state where any user input on the control object  510  is not received. A processor  430  of  FIG. 4  may arrange the control object  510  at a left side of a screen of an electronic device  400  of  FIG. 4  in response to executing the one-handed UI in a left-handed mode. 
         [0131]    According to various embodiments of the present disclosure, the one-handed UI  500  may be activated after a user of the electronic device  400  selects a specified content icon or through a specified gesture of the user. 
         [0132]      FIG. 6  illustrates a drawing of a one-handed UI  600  of a state where a touch-down user input on a control object  610  is received according to various embodiments of the present disclosure. 
         [0133]    Referring to  FIG. 6 , the one-handed UI  600  may include the control object  610 , a pointer  620 , and a function object  630 . The pointer  620  and the function object  630  may be displayed based on touch-down on the control object  610 . The function object  630  may correspond to a hardware button  404  installed in a housing of an electronic device  400 . A user of the electronic device  400  may select a hardware button  402  in a state where he or she holds the electronic device  400  with his or her left hand. However, the user may not select the hardware button  404  in a state where he or she holds the electronic device  400  with his or her left hand. Thus, the processor  430  may display the function object  630  corresponding to the hardware button  404  on a region where the control object  610  is located (e.g., a left region of a screen of the electronic device  400 ). Therefore, the electronic device  400  may allow the user to operate the electronic device  400  with his or her left hand in a state where he or she holds the electronic device  400  with his or her left hand. 
         [0134]    Also, brightness of a screen displayed on the screen may be reduced based on touch-down on the control object  610 . The reducing of the brightness may be shown in  FIG. 6  by a shadow. 
         [0135]    As described above, the function object  630  may be displayed based on the touch-down on the control object  610 . However, embodiments of the present disclosure are not limited thereto. According to various embodiments of the present disclosure, the function object  630  may not be displayed and may then be displayed if the control object  610  is adjacent to the function object  630 . 
         [0136]      FIG. 7  illustrates a drawing of a one-handed UI  700  of a state where a touch drag user input on a control object is received according to various embodiments of the present disclosure. Also,  FIG. 8  illustrates a drawing of a one-handed UI  800  of a state where a touch release user input on a control object  810  is received according to various embodiments of the present disclosure. 
         [0137]    Referring to  FIG. 7 , a processor  430  of  FIG. 4  may move the control object from a location  710   a  to a location  710   b  based on a touch drag user input. The processor  430  may move a pointer from a location  720   a  to a location  720   b  in response to the movement of the control object. The location  720   b  may be a region where a folder icon  730  is located. In this example, the processor  430  may receive a touch release user input on the control object and may perform an operation shown in  FIG. 8  in response to the received touch release user input. 
         [0138]    Referring to  FIG. 8 , the control object  810  and an execution screen  820  may be displayed on the on-handed UI  800 . The folder execution screen  820  may correspond to a result of executing the folder icon  730  and may display a plurality of content icons included in the folder icon  730 . If the pointer in  FIG. 7  is located on an icon for an application, the processor  430  may execute the corresponding application. 
         [0139]    Also, the control object  810  may correspond to the control object of  FIG. 7  and may be displayed on an original location (e.g., a location where a control object  510  of  FIG. 5  is displayed) together with executing the folder icon  730 . 
         [0140]      FIG. 9  illustrates a drawing of a one-handed UI  900  of a state where a touch drag user input on a control object is received according to various embodiments of the present disclosure. 
         [0141]    Referring to  FIG. 9 , a processor  430  of  FIG. 4  may move the control object from a location  910   a  to a location  910   b  based on a touch drag user input. The processor  430  may move a pointer from a location  920   a  to a location  920   b  in response to the movement of the control object. The location  920   b  may be a region which departs from a screen of an electronic device  400  of  FIG. 4 . In  FIG. 9 , the pointer is shown on the location  920   b . However, this is for illustrative purposes of the present disclosure, and the processor  430  may not display the pointer which enters the region  930  any longer. In this example, if a touch release user input on the control object is received, the processor  430  may not execute any operation and may return to a basic state shown in  FIG. 5 . In other words, a user of the electronic device  400  may move the pointer to the region  930  on purpose to cancel a user input on the control object. 
         [0142]      FIG. 10  illustrates a drawing of a one-handed UI  1000  of a state where a control object  1010  is adjacent to a function object according to various embodiments of the present disclosure. 
         [0143]    Referring to  FIG. 10 , a processor  430  of  FIG. 4  may move the control object  1010  to a location adjacent to the function object  1020  based on touch drag on the control object  1010 . In this example, the processor  430  may activate the function object  1020  and may provide an activation indicator as an effect on the activation to a user of an electronic device  400  of  FIG. 4 . The activation indicator shown in  FIG. 10  may be to increase the function object  1020  in size. In this example, the processor  430  may receive a touch release user input on the control object  1010  and may perform an operation corresponding to the function object  1020  in response to the received touch release user input. 
         [0144]      FIG. 11A  illustrates a drawing of a one-handed UI  1100  of a state where a control object  1110  is adjacent to a function object  1120  according to various embodiments of the present disclosure. 
         [0145]    Referring to  FIG. 11A , a processor  430  of  FIG. 4  may move the control object  1110  to a location adjacent to the function object  1120  based on touch drag on the control object  1110   
         [0146]    The function object  1120  may be in a state where the function object  1120  is not displayed, before the control object  1110  is close to the function object  1120 . For example, if the control object  1110  is adjacent to a specified location, for example, a dotted line  1105 , the processor  430  may display the function object  1120 . If the control object  1110  is close to the dotted line  1105 , and the function object  1120  may be displayed while moving from an upper end of a screen of an electronic device  400  of  FIG. 4  to a location shown in  FIG. 11A . 
         [0147]    A state immediately before the function object  1120  is displayed may be a state immediately after a pointer passes an upper end of the screen based on motion of the control object  1110 , and the pointer may be in a state where the pointer is not displayed on the screen. If touch drag on the function object  1120  occurs upwardly in this state, the function object  1120  may be activated and downward motion to a location shown in  FIG. 11A  may be displayed. 
         [0148]    In  FIG. 11A , an embodiment of the present disclosure is exemplified as the function object  1120  is displayed on the center on a vertical axis of the screen. However, embodiments of the present disclosure are not limited thereto. For example, if touch drag on the control object  1110  occur to the left on the vertical axis of the screen, the function object  1120  may be displayed on a corresponding location (e.g., the left on the vertical axis of the screen). The function object  1120  may be an object which performs an operation of unfolding a quick-panel. 
         [0149]      FIG. 11B  illustrates a drawing of a one-handed UI  1100  of a state where a function object  1120  is activated based a location of a control object  1110  according to various embodiments of the present disclosure. 
         [0150]      FIG. 11B , a processor  430  of  FIG. 4  may combine the control object  1110  with the function object  1120  to display the combined control object  1110  and function object  1120 . In this example, an activation indicator for the function object  1120  may be a magnetic effect. For example, the activation indicator may indicate an effect in which the control object  1110  adheres to the function object  1120  having different polarity by moving towards the function object  1120  by gravitation. In this example, part of a quick-panel  1130  may be displayed on an upper end of a screen of an electronic device  400  of  FIG. 4 . 
         [0151]      FIG. 11C  illustrates a drawing of a one-handed UI  1100  where an operation for a function object  1120  is executed according to various embodiments of the present disclosure. 
         [0152]      FIG. 11C , a quick-panel  1130  may be fully displayed on the on-handed UI  1100 . The operation of fully displaying the quick-panel  1130  may be performed through a touch drag user input of lowering a control object  1110  combined with the function object  1120 . The operation may be implemented by implementing an operation of pulling down the quick-panel  1130  as an operation of lowering the function object  1120  through an intuitive UI shown in  FIGS. 11B and 11C . 
         [0153]    According to various embodiments of the present disclosure, after the control object  1110  is combined with the function object  1120  in  FIG. 11B , a processor  430  of  FIG. 4  may receive a touch release user input and may perform an operation of  FIG. 11C . Alternatively, after the control object  1110  is combined with the function object  1120  in  FIG. 11B , if receiving a touch release user input, the processor  430  may release selection for function object  1120 . In this example, the quick-panel may disappear. 
         [0154]      FIG. 12  illustrates a drawing of a one-handed UI  1220  of a state where a pointer  1220  is adjacent to a function object  1230  according to various embodiments of the present disclosure. 
         [0155]    A processor  430  of  FIG. 4  may receive a touch drag user input on a control object  1210  and may move the pointer  1220  in response to the touch drag user input. Referring to FIG.  12 , if the pointer  1220  is adjacent to the function object  1230 , the processor  430  may display the function object  1230 . 
         [0156]    In this example, the function object  1230  may be activated. Next, the processor  430  may receive a touch release user input on the control object  1210  or may receive a touch release user input of lowering the control object  1210 , and may unfold a quick-panel. 
         [0157]    The one-handed UI which operates in the left-handed mode is described with reference to  FIGS. 5 to 12 . A one-handed UI which operates in a right-handed mode will be described below with reference to  FIGS. 13 and 14 . 
         [0158]      FIG. 13  illustrates a drawing of a one-handed UI  1300  of a state where a right-handed mode and a left-handed mode are converted into each other according to various embodiments of the present disclosure.  FIG. 14  illustrates a drawing of a one-handed UI  1400  of a state where a touch-down user input on a control object  1410  is received according to various embodiments of the present disclosure. 
         [0159]    A control object  1310  of  FIG. 13  may be located at the right of a screen of an electronic device  400  of  FIG. 4  to be distinguished from a control object  510  of  FIG. 5 . In other words, a one-handed UI  500  of  FIG. 5  operates in the left-handed mode, whereas the one-handed UI  1300  of  FIG. 13  operates in the right-handed mode. 
         [0160]    According to various embodiments of the present disclosure, the right-handed mode of  FIG. 13  may be converted into the left-handed mode of  FIG. 5 . For example, if the control object  510  is located on a right region of the screen (e.g., a right half region of the screen) and then touch release on the control object  510  occurs through touch-down and touch drag on the control object  510 , a processor  430  of  FIG. 4  may convert the left-handed mode into the right-handed mode. 
         [0161]    In  FIG. 13 , an embodiment of the present disclosure is exemplified as the control object  1310  of  FIG. 13  is located at the same height as the control object  510  of  FIG. 5 . However, embodiments of the present disclosure are not limited thereto. According to various embodiments of the present disclosure, the control object  1310  of  FIG. 13  may differ in height from the control object  510  of  FIG. 5 . The height of the control object  1310  in the right-handed mode may be determined based on a state where a user of the electronic device  400  holds the electronic device  400  with his or her right hand and may be determined to be independent of the left-handed mode. 
         [0162]    Referring to  FIG. 14 , the processor  430  may display a pointer  1420  and a function object  1430  on the one-handed UI  1400  based on a touch-down user input on the control object  1410 . In this example, the function object  1430  of  FIG. 14  may correspond to a hardware button  402  to be distinguished from a one-handed UI  600  of  FIG. 6 . The is because it is difficult for the user to select the hardware button  402  with his or her right hand while holding the electronic device  400  with his or her right hand. For this purpose, the processor  430  may output a control object corresponding to the hardware button  402  with reference to  FIGS. 15A to 15F . 
         [0163]    A longitudinal mode of the electronic device  400  is described with reference to  FIGS. 5 to 14 . Hereinafter, a description will be given of a transverse mode of the electronic device  400 . 
         [0164]      FIGS. 15A to 15F  are drawings illustrating a one-handed UI  1500  for a transverse mode of an electronic device  400  according to various embodiments of the present disclosure. 
         [0165]      FIGS. 15A and 15B  illustrate drawings of one-handed UIs  1500   a  and  1500   b  which operate in a left-handed mode in the transverse mode of the electronic device  400 .  FIGS. 15C and 15D  illustrate drawings of one-handed UIs  1500   c  and  1500   d  which operate in a right-handed mode in the transverse mode of the electronic device  400 . 
         [0166]    Referring to  FIG. 15A , a control object  1510   a  and a pointer  1520   a  may be displayed on the one-handed UI  1500   a . According to various embodiments of the present disclosure, a location of the control object  1510  in the transverse mode of the electronic device  400  may be determined in consideration of a state where a user of the electronic device  400  holds the electronic device  400 . 
         [0167]    Referring to  FIG. 15B , a control object  1510   b , a pointer  1520   b , a first function object  1532   b , and a second function object  1534   b  may be displayed on the one-handed UI  1500   b . Compared with  FIG. 15A , the user of  FIG. 15A  may select a first hardware button  402  or a second hardware button  440  in a state where he or she holds the electronic device  400  with his or her left hand. However, the user of  FIG. 15B  may not select the first hardware button  402  or the second hardware button  404  in the state where he or she holds the electronic device  400  with his or her left hand. Thus, the first function object  1532   b  and the second function object  1534   b  may be further displayed on the one-handed UI  1500   b  to be distinguished from the one-handed UI  1500   a  of  FIG. 15A . 
         [0168]    According to various embodiments of the present disclosure, the first function object  1532   b  and the second function object  1534   b  may be changed in location to each other. 
         [0169]    Referring to  FIG. 15C , a control object  1510   c  and a pointer  1520   c  may be displayed on the one-handed UI  1500   c . According to various embodiments of the present disclosure, a location of the control object  1510  in the transverse mode of the electronic device  400  may be determined in consideration of a state where the user holds the electronic device  400 . 
         [0170]    Referring to  FIG. 15D , a control object  1510   d , a pointer  1520   d , a first function object  1532   d , and a second function object  1534   d  may be displayed on the one-handed UI  1500   d . Compared with  FIG. 15C , the user of  FIG. 15C  may select the first hardware button  402  or the second hardware button  404  in a state where he or she holds the electronic device  400  with his or her right hand. However, it may be difficult for the user of  FIG. 15D  to select the first hardware button  402  or the second hardware button  404  in the state where he or she holds the electronic device  400  with his or her right hand. Thus, the first function object  1532   d  and the second function object  1534   d  may be further displayed on the one-handed UI  1500   d  of  FIG. 15D  in connection with selecting a hardware button to be distinguished from the one-handed UI  1500   c  of  FIG. 15C . 
         [0171]    According to various embodiments of the present disclosure, the first function object  1532   d  and the second function object  1534   d  may be changed in location to each other. 
         [0172]    Referring to  FIG. 15E , a one-handed UI  1500   e  may be similar to the one-handed UI  1500   a  of  FIG. 15A , but a first function object  1532   e  and a second function object  1534   e  may be displayed on the one-handed UI  1500   e . In this example, the first hardware button  402  or the second hardware button  404  may be deactivated. 
         [0173]    Similarly, referring to  FIG. 15F , a one-handed UI  1500   f  may be similar to the one-handed UI  1500   c  of  FIG. 15C , but a first function object  1532   f  and a second function object  1534   f  may be displayed on the one-handed UI  1500   f . In this example, the first hardware button  402  or the second hardware button  404  may be deactivated. 
         [0174]      FIGS. 16A and 16B  are drawings illustrating a one-handed UI  1600  of a state where a touch hold user input on a control object  1610  is received according to various embodiments of the present disclosure. 
         [0175]    Referring to  FIG. 16A , if receiving a touch hold user input on the control object  1610 , a processor  430  of  FIG. 4  may display an indicator for the touch hold user input. 
         [0176]    According to various embodiments of the present disclosure, the indicator may be an operation where a gauge is filled around a pointer  1620 . 
         [0177]    Referring to operations “ 1601 - 1604 ” of  FIG. 16A , an indicator  1630  may vary over a time when the touch hold user input continues. The operations “ 1601 - 1603 ” may indicate a state where it is insufficient to perform an operation corresponding to the touch hold user input. The operation “ 1604 ” may indicate a state where the operation corresponding to the touch hold user input may be performed. 
         [0178]    The processor  430  may perform a long press operation on a folder icon  1605  where the pointer  1620  is located, based on a touch hold user input on the control object  1610 . The operation is shown in  FIG. 16B . 
         [0179]    Referring to  FIG. 16B , the processor  430  may activate a mode of moving a location of a content icon or deleting the content icon by the long press operation on the folder icon  1605 . 
         [0180]      FIGS. 17A and 17B  illustrate drawings of a location where a control object is displayed again upon touch release on a control object on a one-handed UI according to various embodiments of the present disclosure. 
         [0181]    Referring to  FIGS. 17A and 17B , the one-handed UI may include a first boundary line  1700  and a second boundary line  1705 . The first boundary line  1700  and the second boundary line  1705  may be actually displayed on the one-handed UI, but may be shown for illustrative purposes. 
         [0182]    A drawing shown in the left of  FIG. 17A  illustrates that the control object is released on a first location  1710   a . A processor  430  of  FIG. 1  may determine that a location where the control object is released is in the range of the first boundary line  1700  to the second boundary  1705 . In this example, as shown in the right of  FIG. 17A , the processor  430  may display the control object on a second location  1715   a.    
         [0183]    If comparing before and after the control object is released, the control object may have a released y coordinate without change and may have an x coordinate which is “0” (e.g., a specified start point). 
         [0184]    Thus, a user of an electronic device  400  of  FIG. 4  may move the control object in the range of the first boundary line  1700  to the second boundary line  1705 . In this example, as described above, an x coordinate may be “0”. 
         [0185]    A drawing shown in the left of  FIG. 17B  illustrates that the control object is released on a first location  1710   b . The processor  430  may determine that a location where the control object is released departs from the range of the first boundary line  1700  to the second boundary line  1705 . In this example, as shown in the right of  FIG. 17B , the processor  430  may display the control object on a second location  1715   b.    
         [0186]    Comparing before and after the control object is released, a “y” coordinate of the control object may have a coordinate of the first boundary line  1700 , and an “x” coordinate may be “0”. 
         [0187]    If the location where the control object is released is lower than a “y” coordinate of the second boundary line  1705 , a “y” coordinate of the control object, after the control object is released, may be a “y” coordinate of the second boundary line  1705 . 
         [0188]    Referring to  FIGS. 17A and 17B , it may be seen that a location after the control object is released does not depart from the range of the first boundary line  1700  to the second boundary line  1705 . Thus, the first boundary line  1700  and the second boundary line  1705  may be determined based on a level necessary for a one-handed operation.
