     An embodiment of the disclosure will be described in greater detail below with reference to the accompanied drawings. 
       FIGS.  1 A and  1 B  are diagrams illustrating a method of identifying a touch position of a user according to various embodiments of the disclosure. 
       FIGS.  1 A and  1 B  are for describing a touch sensing method of a capacitance method, where  FIG.  1 A  represents an example of a contact touch input and  FIG.  1 B  represents an example of a non-contact touch input. 
     Referring to  FIG.  1 A , an electronic apparatus  100  may include a display panel (not shown) which constitutes a touch screen together with a touch panel, and may include at least one from among a smartphone, a tablet personal computer (PC), a mobile medical device, a wearable device, an interactive whiteboard, and a kiosk, but is not limited thereto. Accordingly, in the drawings below which include  FIG.  1 A , an embodiment of the electronic apparatus  100  being implemented as a tablet PC is shown, but is not limited thereto. 
     According to an embodiment, when a contact touch is input using a body part of a user, for example a finger, as shown in  FIG.  1 A , the electronic apparatus  100  may obtain a magnitude of a capacitance signal through a capacitive sensor (not shown). The magnitude of the capacitance signal may be obtained as follows. 
     
       
         
           
             
               
                 
                   C 
                   = 
                   
                     ε 
                     × 
                     
                       A 
                       d 
                     
                   
                 
               
               
                 
                   Equation 
                   ⁢ 
                       
                   1 
                 
               
             
           
         
       
     
     C represents the magnitude of the capacitance signal, ε represents a dielectric constant, A represents a contact surface with the capacitive sensor, and a represents a distance between the capacitive sensor and an object, and the magnitude of the capacitance signal may be proportional to the contact surface and inversely proportional to the distance with the sensor. 
     The electronic apparatus  100  may identify a position at which the magnitude of the capacitance signal obtained by the capacitive sensor (not shown) is at its greatest as the touch position. Then, the electronic apparatus  100  may perform an operation which corresponds to the identified touch position. 
     Referring to  FIG.  1 B , when the non-contact touch is input using a body part of the user, for example, a finger, the electronic apparatus  100  may obtain the magnitude of the capacitance signal through the capacitive sensor (not shown). 
     For example, when there is a non-contact type touch input which uses a finger of the user, because a difference in a distance magnitude of the finger spread by the user with the capacitive sensor  120  of  FIG.  2    and a distance magnitude of the remaining fingers with the capacitive sensor  120  of  FIG.  2    is relatively smaller compared to a contact type, a difference in magnitude of an amount of change in capacitance which corresponds to a body part of the user may be relatively smaller compared to the contact type. 
     For example, a value of a first capacitance signal magnitude  10  obtained based on the size of A1 and d1 and a value of a second capacitance signal magnitude  20  obtained based on the size of A2 and d2 may be similar or the latter may be greater. 
     Based on the second capacitance signal magnitude  20  being greater, the electronic apparatus  100  may identify a position corresponding to a second capacitance signal magnitude  20  as the touch position, and there may be an instance where another position which is not the position intended by the user is identified as the touch position. However, the problem described above is not limited to the non-contact type touch input, and may arise even in the contact type touch input. 
     Accordingly, various embodiments identifying the touch position intended by the user from among a plurality of touch positions will be described below taking into consideration orientation information of the electronic apparatus and information on the touch position. 
       FIG.  2    is a block diagram illustrating a configuration of an electronic apparatus according to an embodiment of the disclosure. 
     Referring to  FIG.  2   , the electronic apparatus  100  may include a display panel  110 , a capacitive sensor  120 , an acceleration sensor  130 , and a processor  140 . 
     The display panel  110  may be implemented as a display including a self-emissive device or a display including a non-emissive device and a backlight. For example, the display panel  110  may be implemented as a display of various forms such as, for example, and without limitation, a liquid crystal display (LCD), an organic light emitting diode (OLED) display, a light emitting diodes (LEDs), a micro LED, a mini LED, a plasma display panel (PDP), a quantum dot (QD) display, a quantum dot light emitting diodes (QLED), and the like. In the display panel  110 , a driving circuit, which may be implemented in the form of an amorphous silicon thin film transistor (a-si TFT), a low temperature poly silicon (LTPS) TFT, an organic TFT (OTFT), or the like, a backlight unit, and the like may be included. 
     The display panel  110  may be implemented as a flexible display, a rollable display, a three-dimensional display (3D display), a display in which a plurality of display modules is physically coupled, and the like. In addition, the display panel  110  may be configured as a touch screen together with a touch panel, and may be formed of a flexible panel. 
     The capacitive sensor  120  may sense capacitance by a capacitor which is an electrical device connected with an electrode, a matter equivalent thereto, a human body contact, and the like. The processor (not shown) may obtain the amount of change in capacitance according to a change in distance and change in contact area between the electrode within the capacitive sensor  120  with the capacitor or a matter equivalent thereto. The capacitive sensor  120  may be disposed at a lower part of the display panel  110 . In this case, the capacitive sensor  120  may be implemented as a capacitance panel disposed at the lower part of the display panel  110 , or implemented with a plurality of capacitive sensors being disposed spaced apart from one another at the lower part of the display panel  110 . 
     The acceleration sensor  130  may be a sensor configured to measure an acceleration speed of an object or an intensity of impact. According to an embodiment, the acceleration sensor  130  may identify dynamic force such as acceleration, vibration, and impact of an object by processing an output signal. The acceleration sensor  130  may be one, but may also be in plurality. Based on there being one acceleration sensor  130 , the acceleration sensor  130  may be disposed on a main board on which basic components are mounted, but is not limited thereto. Based on there being multiple acceleration sensors  130 , the acceleration sensors  130  may be disposed at a position spaced apart from one another, for example, the main board, a sub board, a bezel, and the like. 
     The processor  140  may control the overall operation of the electronic apparatus  100 . Specifically, the processor  140  may control the overall operation of the electronic apparatus  100  connected to respective configurations of the electronic apparatus  100 . The processor  140  may perform, by executing at least one instruction stored in a memory (not shown), an operation of the electronic apparatus  100  according to various embodiments. 
     According to an embodiment, the processor  140  may be designated to various designations such as, for example, and without limitation, a digital signal processor (DSP), a microprocessor, a central processing unit (CPU), a micro controller unit (MCU), a micro processing unit (MPU), a neural processing unit (NPU), a controller, an application processor (AP), and the like, but is described as the processor  140  in the disclosure. 
     The processor  140  may be implemented as a system on chip (SoC) or a large scale integration (LSI), and may be implemented in the form of a field programmable gate array (FPGA). In addition, the processor  140  may include a volatile memory such as static random access memory (SRAM). 
     Below, the disclosure will be described assuming that an axis parallel with a relatively long edge from among a plurality of edges is an X-axis, an axis parallel with a relatively short edge is a Y-axis, and an axis perpendicular with the respective X-axis and Y-axis is a Z-axis. However, the embodiment is not limited thereto, and the axis parallel with the relatively long edge from among the plurality of edges may be one of the Y-axis or the Z-axis. 
     According to an embodiment, the processor  140  may identify the orientation information of the electronic apparatus  100  based on a first sensing data obtained by the acceleration sensor  130 . The processor  140  may obtain a magnitude of acceleration of the respective axis directions that is applied to the electronic apparatus  100  through the acceleration sensor  130 , and the first sensing data may include information on the acceleration magnitude of the respective axis directions that is applied to the electronic apparatus  100 . 
     According to an example, the processor  140  may identify the orientation information of the electronic apparatus  100  based on the first sensing data obtained by the acceleration sensor  130 . In this case, the orientation information may include information on an angle formed by the respective axes with a direction of gravity acceleration. However, for convenience of description, it may be assumed that the Z-axis forms 90° with the direction of gravity acceleration in the description below. 
     According to an example, based on the Y-axis of the electronic apparatus  100  being parallel with the direction of gravity acceleration, the processor  140  may obtain data having a size of 0G (here, 1G is the same as a magnitude of gravity acceleration) in the X-axis direction and a size of 1G in the Y-axis direction through the acceleration sensor  130 , and based therefrom, identify as the X-axis and the Y-axis forming angles of 90° and 0° with the direction of gravity acceleration, respectively. 
     According to another example, based on the X-axis of the electronic apparatus  100  being parallel with the direction of gravity acceleration, the processor  140  may obtain data having the size of 0G in the Y-axis direction and the size of 1G in the X-axis direction through the acceleration sensor  130 , and based therefrom, identify as the X-axis and the Y-axis forming angles of 0° and 90° with the direction of gravity acceleration, respectively. 
     According to another example, based on the X-axis of the electronic apparatus  100  forming a 45° with a floor surface, the processor  140  may obtain data having a size of

     in the Y-axis direction through the acceleration sensor  130 , and based therefrom, identify as the X-axis and the Y-axis forming a 45° with the direction of gravity acceleration, respectively. 
     According to an embodiment, the processor  140  may identify the plurality of touch positions corresponding to touch data of greater than or equal to a threshold value from the display panel  110  based on a second sensing data obtained by the capacitive sensor  120 . The second sensing data may include the amount of change in capacitance, and the amount of change in capacitance may be obtained based on an amount of change in distance magnitude between the capacitive sensor  120  and the body part which is in proximity and an amount of change in a size of the contact area between the sensor and the body part. The amount of change in capacitance may be inversely proportionate to the amount of change in distance magnitude and proportionate to the size of the contact area. The amount of change in capacitance may be obtained based on a magnitude of capacitance prior to the touch input of the user and the magnitude of capacitance corresponding to the touch input of the user. The touch input may be the contact type touch input or the non-contact type touch input, but will be described below assuming that it is the non-contact type touch input for convenience of description. 
     According to an example, the processor  140  may identify the plurality of touch positions corresponding to touch data of greater than or equal to the threshold value based on the amount of change in capacitance. The touch data may be data which can identify whether there is touch input obtained based on an amount of change in capacitance data. For example, the touch data may be capacitance data itself, or may be data normalizing capacitance data, data converted based on a pre-set reference value, and the like. For convenience of description, it will be described below assuming that touch data is capacitance itself. 
     Based on the capacitive sensor  120  being implemented as the capacitance panel disposed at the lower part of the display panel  110 , the processor  140  may identify the plurality of touch positions at which the amount of change in capacitance is greater than or equal to the threshold value based on the amount of change in capacitance obtained by the capacitive sensor  120 . According to an example, the processor  140  may identify all positions at which the amount of change in capacitance is greater than or equal to the threshold value as the plurality of touch positions, or identify only positions of a threshold coefficient (e.g.,  2 ) from among a plurality of positions of greater than or equal to the threshold value as the plurality of touch positions. For example, in a latter case, a position having a peak value with the greatest amount of change in capacitance and a next peak value may be identified as the plurality of touch positions. The threshold value may be pre-stored in the memory (not shown) at an initial manufacturing stage, but may be set or changed according to a user command. 
     Then, the processor  140  may obtain coordinate information corresponding to the identified plurality of touch positions. The coordinate information may include an X-axis coordinate and a Y-axis coordinate. 
     According to an embodiment, the processor  140  may identify a touch position at a relatively upper side from among the plurality of touch positions as the touch position intended by the user based on the orientation information and the coordinate information corresponding to the respective touch positions. This is because the user may touch the position intended by oneself generally using a finger, and in this case, unintended capacitance may occur due to touching with a palm, a back of one&#39;s hand, and the like at a lower side area of the corresponding position, and an axis for determining an upper side position from among the axes (X-axis, Y-axis) corresponding to the coordinates corresponding to the touch position may vary according to an orientation of the electronic apparatus  100 . 
     Accordingly, the processor  140  may determine an axis for determining the upper side position based on the orientation information, and identify an upper side touch position based on a coordinate value corresponding to the determined axis. 
     For example, the processor  140  may identify, based on information on an angle of which the respective axes form with the gravity acceleration direction, an axis value of an axis of which a magnitude of an angle formed with the direction of gravity acceleration is the smallest from among the plurality of axes. For example, the processor  140  may determine, based on the X-axis and the Y-axis being identified as forming angles of 90° and 0° respectively with the direction of gravity acceleration by the capacitive sensor  120 , the Y-axis which has a small magnitude of an angle that is formed with the direction of gravity acceleration as the axis to determine the upper side position based on the above, and identify the upper side touch position based on the coordinate value corresponding to the determined Y-axis. 
     For example, the touch position corresponding to a relatively great Y-axis value from among the respective Y-axis coordinate values corresponding to the plurality of touch positions may be identified as the upper side touch position. For example, an absolute value of the identified at least one Y-axis value from among the coordinate values corresponding to the respective touch positions may be compared and the touch position at a relatively upper side from among the plurality of touch positions may be identified. 
     In another example, the processor  140  may determine, based on the X-axis and the Y-axis being identified as forming angles of 0° and 90° respectively with the direction of gravity acceleration by the capacitive sensor  120 , the X-axis which has a relatively small magnitude of an angle that is formed with the direction of gravity acceleration as the axis to determine the upper side position based on the above, and identify the upper side touch position based on the coordinate value corresponding to the determined X-axis. 
     In another example, the processor  140  may determine, based on the X-axis and the Y-axis being identified as forming angles of 45° and 45° respectively with the direction of gravity acceleration by the capacitive sensor  120 , both the X-axis and the Y-axis as axes to determine the upper side position. 
     According to an embodiment, the processor  140  may identify a disposition mode of the electronic apparatus  100  based on the orientation information, and decide the axis to determine the upper side position based on the identified mode. 
     According to an embodiment, the processor  140  may identify the electronic apparatus  100  to be in a horizontal mode or a vertical mode based on the orientation information. The horizontal mode may mean an image displayed by the display panel  110  being an image in a horizontal direction, and the horizontal direction image may mean an image in which a horizontal size (i.e., a size corresponding to the X-axis) is greater than a vertical size (i.e., a size corresponding to the Y-axis). The vertical mode may mean an image displayed by the display panel  110  being an image in a vertical direction, and the vertical direction image may mean an image in which the vertical size is greater than the horizontal size. 
     According to an example, the processor  140  may identify, based on a magnitude of an angle formed by the X-axis of the electronic apparatus  100  with the direction of gravity acceleration being identified as less than a threshold magnitude based on the obtained orientation information, the electronic apparatus  100  as in the vertical mode. In this case, the threshold magnitude may be 45°, but is not limited thereto. 
     For example, based on the threshold magnitude being 45°, the processor  140  may identify the electronic apparatus  100  to be in the vertical mode based on the angle formed by the X-axis of the electronic apparatus  100  and the direction of gravity acceleration being identified as 30° by the acceleration sensor  130 . 
     According to an example, the processor  140  may identify, based on the magnitude of the angle formed by the X-axis of the electronic apparatus  100  with the direction of the gravity acceleration being identified as greater than or equal to the threshold magnitude based on the obtained orientation information, the electronic apparatus  100  as in the horizontal mode. 
     For example, based on the threshold magnitude being 45°, the processor  140  may identify the electronic apparatus  100  to be in the horizontal mode based on the angle formed by the X-axis of the electronic apparatus  100  and the direction of gravity acceleration being identified as 60° by the acceleration sensor  130 . 
     According to an example, the processor  140  may identify, based on the electronic apparatus  100  being identified as in the horizontal mode based on the orientation information, a relatively upper side touch position from among the plurality of touch positions by comparing the Y-axis values from among the coordinate values corresponding to the respective touch positions. 
     For example, the processor  140  may identify, based on the electronic apparatus  100  being identified as in the horizontal mode due to the angle formed by the X-axis with the direction of gravity acceleration being identified as greater than or equal to the threshold magnitude by the acceleration sensor  130 , the touch position at which a magnitude of the Y-axis value is relatively greater as the relatively upper side touch position by comparing the magnitude of the Y-axis value from among the coordinate values corresponding to the respective touch positions. In this case, the processor  140  may identify the relatively upper side touch position from among the plurality of touch positions by comparing a magnitude of the absolute value of the Y-axis value. 
     According to another example, the processor  140  may identify, based on the electronic apparatus  100  being identified as in the vertical mode based on the orientation information, the relatively upper side touch position from among the plurality of touch positions by comparing the X-axis value from among the coordinate values corresponding to the respective touch positions. 
     For example, the processor  140  may identify, based on the electronic apparatus  100  being identified as in the vertical mode due to the angle formed by the X-axis and the direction of gravity acceleration being identified as less than the threshold magnitude by the acceleration sensor  130 , the touch position at which the magnitude of the X-axis value is relatively greater as the relatively upper side touch position by comparing the magnitude of the X-axis value from among the coordinate values corresponding to the respective touch positions. In this case, the processor  140  may identify the relatively upper side touch position from among the plurality of touch positions by comparing the magnitude of the absolute value of the X-axis value. 
     According to an embodiment, the processor  140  may identify, based on the electronic apparatus  100  being identified as tilted in a gravity direction in case the electronic apparatus  100  is not identified as in the horizontal mode of the vertical mode, the relatively upper side touch position from among the plurality of touch positions by comparing the absolute value for the identified at least one axis value from among the coordinate values corresponding to the respective touch positions. 
     The gravity direction may mean the gravity acceleration direction, and the processor  140  may identify a degree to which the electronic apparatus  100  is tilted in the gravity direction based on information on an angle formed by the X-axis with an axis (hereinafter, referred to as a gravity direction axis) parallel with the direction of gravity acceleration. 
     In addition, according to an example, the processor  140  may calculate, based on the electronic apparatus  100  being identified as tilted in the gravity direction, a gravity direction value (or a gravity direction height value or a first value or a second value) corresponding to the respective touch positions based on a square root value of a value in which the X-axis value and the Y-axis value are squared and summated from among the coordinate values corresponding to the plurality of touch positions, the orientation information of the electronic apparatus  100 , and a ratio of the Y-axis value with respect to the X-axis value of the plurality of touch positions, and identify the touch position corresponding to a relatively great value from among a plurality of gravity direction values as the relatively upper side touch position. 
     The gravity direction value may mean an intercept value corresponding to the gravity direction axis, and specifically, may be calculated through an equation as described below.

The processor  140  may identify a first touch position  301  corresponding to a second finger of the user and a second touch position  302  corresponding to the remaining fingers of the user, and based therefrom, obtain the coordinate information of the respective touch positions. The processor  140  may obtain the coordinate information based on the distance magnitude between the plurality of touch positions and the respective axes, and the magnitude of the coordinate value may be a relative value corresponding to the distance magnitude between the respective touch positions and an axis. Accordingly, the processor  140  may identify the coordinate values of the first and second touch positions  301  and  302  as (9,13) and (11,6), respectively.

Accordingly, the processor  140  may identify the first touch position  301  which is relatively greater in the size of Y-axis value corresponding to the respective touch positions, and perform an operation corresponding to the identified first touch position. 
     Referring to  FIGS.  3 A and  3 B , the processor  140  may identify the touch position intended by the user even when the position at which the size of capacitance is greater than or equal to a pre-set threshold value is in plurality  303  and  304 , and user satisfaction may be enhanced as a rate of error in touch is reduced accordingly. 
       FIGS.  4 A and  4 B  are diagrams illustrating an identification method of a touch position at a relatively upper side from the vertical mode according to various embodiments of the disclosure.

       FIGS.  5 A and  5 B  are diagrams illustrating an identification method of a touch position at a relatively upper side according to various embodiments of the disclosure. 
     Referring to  FIGS.  5 A and  5 B , the processor  140  may identify that the magnitude of the angle  510  formed by the X-axis of the electronic apparatus  100  with the gravity direction axis is 50° which is within a pre-set threshold range (greater than or equal to 30° and less than 60°) based on the first sensing data obtained by the acceleration sensor  130 . 
     In addition, based on there being the touch input of the user, the processor  140  of the electronic apparatus  100  may identify the plurality of touch positions  501  and  502  corresponding to touch data of greater than or equal to the threshold value based on the second sensing data obtained by the capacitive sensor  120 . The processor  140  may identify the touch position  501  corresponding to the second finger of the user and the touch position  502  corresponding to the remaining fingers of the user, and based therefrom, obtain the coordinate information of the respective touch positions. The processor  140  may obtain the coordinate information based on the distance magnitude between the plurality of touch positions and the respective axes, and the magnitude of the coordinate value may be a relative value corresponding to the distance magnitude between the respective touch positions and an axis. Accordingly, the processor  140  may identify the coordinate values of the respective positions  501  and  502  as (15,15) and (12,8), respectively.

     The memory  150  may store data necessary for the various embodiments of the disclosure. The memory  150  may be implemented in the form of a memory embedded in the electronic apparatus  100 ′ according to a data storage use, or implemented in the form of a memory attachable to and detachable from the electronic apparatus  100 ′. For example, data for operating the electronic apparatus  100 ′ may be stored in a memory embedded in the electronic apparatus  100 ′, and data for an expansion function of the electronic apparatus  100 ′ may be stored in a memory attachable to and detachable from the electronic apparatus  100 ′. The memory embedded in the electronic apparatus  100 ′ may be implemented as at least one from among a volatile memory (e.g., a dynamic random access memory (DRAM), a static RAM (SRAM), or a synchronous dynamic RAM (SDRAM)), or a non-volatile memory (e.g., one time programmable ROM (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., NAND flash or NOR flash), a hard disk drive (HDD) or a solid state drive (SSD)).

For example, the user interface  160  may include at least one from among a touch sensor, a motion sensor, a button, a jog dial, a switch, a microphone, or a speaker, but is not limited thereto. 
     The output part  170  may include the speaker, a vibration generating part, and the like, and is not limited thereto, and may be formed into various embodiments which transfers information in a form that may be sensed by five senses of the user. 
       FIG.  7    is a flowchart illustrating a control method of an electronic apparatus according to an embodiment of the disclosure. 
     Referring to  FIG.  7   , according to the control method of the electronic apparatus, first, the orientation information of the electronic apparatus may be identified based on the first sensing data obtained by the acceleration sensor (S 710 ). 
     Then, the plurality of touch positions corresponding to touch data of greater than or equal to the threshold value may be identified from the display based on the second sensing data obtained by the capacitive sensor (S 720 ). In addition, the capacitive sensor may be implemented as a capacitance panel disposed at the lower part of the display panel, or implemented as a plurality of capacitive sensors disposed spaced apart from one another at the lower part of the display panel. 
     Then, the relatively upper side touch position from among the plurality of touch positions may be identified based on the coordinate information corresponding to the orientation information and the respective touch positions (S 730 ). 
     Then, an operation corresponding to the identified touch position may be performed (S 740 ). 
     Here, the coordinate information corresponding to the respective touch positions may include the X-axis value and the Y-axis value. In this case, in operation S 730 , at least one axis from among the X-axis and the Y-axis may be identified based on the orientation information, and the relatively upper side touch position from among the plurality of touch positions may be identified by comparing the axis value corresponding to the identified axis from the coordinate values corresponding to the respective touch positions. 
     In this case, in operation S 730 , based on the electronic apparatus being identified as in the horizontal mode based on the orientation information, the relatively upper side touch position from among the plurality of touch positions may be identified by comparing the Y-axis value from among the coordinate values corresponding to the respective touch positions. Alternatively, in operation S 730 , based on the electronic apparatus being identified as in the vertical mode based on the orientation information, the relatively upper side touch position from among the plurality of touch positions may be identified by comparing the X-axis value from among the coordinate values corresponding to the respective touch positions. 
     In operation S 730 , based on the electronic apparatus being identified as in the horizontal mode, the touch position at which the magnitude of the Y-axis value is relatively great may be identified as the relatively upper side touch position by comparing the magnitude of the Y-axis value from among the coordinate values corresponding to the respective touch positions. Alternatively, in operation S 730 , based on the electronic apparatus being identified as in the vertical mode, the touch position at which the magnitude of the X-axis value is relatively great may be identified as the relatively upper side touch position by comparing the magnitude of X-axis value from among the coordinate values corresponding to the respective touch positions. 
     In addition, in operation S 730 , at least one axis from among the X-axis and the Y-axis may be identified based on the orientation information, and the relatively upper side touch position from among the plurality of touch positions may be identified by comparing the absolute value of the value corresponding to the identified at least one axis from among the coordinate values corresponding to the respective touch positions. 
     Here, in operation S 730 , based on the electronic apparatus being identified as tilted in the gravity direction, the relatively upper side touch position from among the plurality of touch positions may be identified by comparing the absolute value of the identified plurality of axis values from among the coordinate values corresponding to the respective touch positions. 
     Here. In operation S 730 , the touch position corresponding to the relatively great value may be identified as the relatively upper side touch position by comparing a square root value of a value in which the X-axis value and the Y-axis value are squared and summated from among the coordinate values corresponding to the first touch position and a square root value of a value in which the X-axis value and the Y-axis value are squared and summated from among the coordinate values corresponding to the second touch position. 
     In addition, in operation S 720 , based on the non-contact type touch input being received, the plurality of touch positions corresponding to touch data of greater than or equal to the threshold value may be identified in the display based on the second sensing data. 
     According to the various embodiments of the disclosure, the touch position intended by the user from among the plurality of touch positions may be accurately identified taking into consideration the orientation information and information on the touch position of the electronic apparatus. Accordingly, user convenience may be enhanced.
