     Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings. 
       FIG. 1  is a block diagram illustrating a configuration of a display apparatus according to an exemplary embodiment. 
     As illustrated in  FIG. 1 , a display apparatus  100  is configured to include a display unit  110 , an input unit  120 , and a control unit  130 . 
     The display unit  110  displays an image. In detail, the display unit  110  may display an image such as a broadcasting content transmitted from a broadcasting station, a video on demand (VOD), or the like. 
     In addition, the display unit  110  may display a menu for executing a basic program. Here, the menu may include menu items for executing the basic program that may provide a basic function of the display apparatus  100 . 
     Meanwhile, the display unit  110  may be implemented by a liquid crystal display (LCD), an organic light emitting display (OLED), a plasma display panel (PDP), or the like. 
     The input unit  120  receives a user command. In detail, the input unit  120  may receive a user command for controlling the display apparatus  100 . 
     Here, the user command for controlling the display apparatus  100  may include a button manipulation of a remote control apparatus, a pointing manipulation of the remote control apparatus, a manipulation using a touch panel included in the remote control apparatus, a user motion, a user speech, and the like. Here, the remote control apparatus may be implemented by a remote controller, a pointing device, or the like. 
     The control unit  130  may control a general operation of the display apparatus  100  and be called a central processing unit, a microprocessor, a processor, or the like. 
     In addition, in the case in which a user interface (UI) or graphical user interface (GUI) generating command is input through the input unit  120 , the control unit  130  controls the display unit  110  to display a first UI. 
     In detail, when the UI generating command is input through the input unit  120 , the control unit  130  may control the display unit  110  to display the first UI. For example, when a user presses a specific button of the remote control apparatus, takes a specific pointing action using the remote control apparatus, takes a specific action using the touch panel included in the remote control apparatus, takes a specific motion, or speaks a specific word, the control unit  130  may recognize that the UI generating common is input and control the display unit  110  to display the first UI. 
     Meanwhile, when the UI generating command is input during a period in which a highlight is displayed in one of a plurality of menu items displayed on the display unit  110  (that is, the item is implicitly selected), the control unit  130  may control the display unit  110  to display the first UI or GUI in the vicinity of the menu item in which the highlight is displayed. 
     In detail, the control unit  130  may control the display unit  110  to display the plurality of menu items on the display unit  110 . In addition, when the user performs a manipulation for moving between the plurality of menu items, the control unit  130  may control the display unit  110  to display the vicinity of a menu item to which the user wants to move as a highlight or implicit selection. In this case, when the user inputs a manipulation for generating the first UI, the control unit  130  may control the display unit  110  to display the first UI in the vicinity of the menu item in which the highlight is displayed. 
     Meanwhile, when the UI generating command is input during a period in which a pointer is displayed on the display unit  110 , the control unit  130  may control the display unit  110  to change the pointer into the first UI and display the first UI or GUI. 
     In detail, the control unit  130  may control the display unit  110  to display the pointer moving in a direction corresponding to a direction manipulation of the user on the display unit  110 . In this case, when the user inputs a manipulation for generating the first UI, the control unit  130  may control the display unit  110  to change the pointer into the first UI and display the first UI. 
     Meanwhile, the control unit  130  controls the display unit  110  to display the first UI including one or more UI elements. In detail, the first UI may include UI elements corresponding to the respective functions of the display apparatus  100 . For example, the first UI may include one or more of a UI element corresponding to a volume adjusting function, a UI element corresponding to a setting function, a UI element corresponding to a channel list searching function, and a UI element corresponding to a recently viewed channel searching function. 
     Meanwhile, the user may control the UI elements or GUI in a plurality of control schemes or interaction methods. In detail, the user may select the UI elements using at least one of a control scheme using direction keys of the remote control apparatus, a control scheme using pointing motion of the remote control apparatus, a control scheme using the touch panel included in the remote control apparatus, a control scheme using photographed (or captured) user motion, and a control scheme using user speech. 
     In addition, when the user selects a direction key of a specific direction of the remote control apparatus, the control unit  130  may recognize that a UI element of a direction corresponding to a user command is selected and execute a function corresponding to the selected UI element. 
     Further, when the user moves a pointer in a specific direction using a remote control apparatus having a pointing function, the control unit  130  may recognize that a UI element of a direction corresponding to a user command is selected and execute a function corresponding to the selected UI element. 
     Further, when the user touches the touch panel of the remote control apparatus in a specific direction, the control unit  130  may recognize that a UI element of a direction corresponding to a user command is selected and execute a function corresponding to the selected UI element. 
     Further, when the user takes a motion moving his/her hand, arm, or the like, in a specific direction, the control unit  130  may recognize that a UI element of a direction corresponding to a user motion command is selected and execute a function corresponding to the selected UI element or GUI. 
     Further, when the user inputs a word representing a specific direction, the control unit  130  may recognize that a UI element of a direction corresponding to a user command is selected and execute a function corresponding to the selected UI element. 
     Meanwhile, first and second UIs may include four UI elements or controls (widgets) corresponding to four directions. In detail, the control unit  130  may control the display unit  110  to divide a first UI region into an upper region, a lower region, a left region, and a right region and display the first UI including the UI elements or controls on each of the divided regions. Likewise, the control unit  130  may control the display unit  110  to divide a second UI region into an upper region, a lower region, a left region, and a right region and display the second UI including the UI elements on each of the divided regions. 
     In this case, when a user command corresponding to one of the four directions is input, the control unit  130  may execute a function of a UI element or GUI of a direction corresponding to the user command. In detail, when the user inputs a direction manipulation in a state in which the first UI is displayed on the display unit  110 , the control unit  130  may recognize that a UI element of a direction corresponding to the user command is selected and execute a function corresponding to the selected UI element. 
     For example, when the user inputs a direction manipulation to the left passes over the controls on the left, the control unit  130  may recognize that a UI element of a direction corresponding to the user command is selected. In this case, when a function corresponding to a UI element present in the left region of the first UI region is volume adjustment, the control unit  130  may execute a volume adjusting function. 
     Meanwhile, when the UI element of the direction corresponding to the user command is selected, the control unit  130  may control the display unit  110  to display a second UI including UI elements or further GUI corresponding to sub-functions of a function of the selected UI element. For example, when the user selects a UI element of a left direction and a function corresponding to the selected UI element is volume adjustment, a newly displayed second UI or GUI may include UI elements corresponding to sub-functions (for example, volume-up (by one step), volume-down (by one step), volume-up (by three steps), and volume-down (by three steps)) of the volume adjusting function. 
     Here, in the case in which a preset user motion is input through the input unit, the control unit  130  controls the display unit  110  to display a second UI including UI elements different from at least one of one or more UI elements included in the first UI. 
     Here, the preset user motion may be an action of pressing a specific button of the remote control apparatus, an action of shaking the remote control apparatus, an action of overturning the remote control apparatus, a specific pointing action using the remote control apparatus, a specific action (an action of pressing a touch pad, an action of simultaneously pressing two points, or the like) using the touch panel of the remote control apparatus, a specific motion (an action of shaking a hand, an arm, or the like, an action of overturning the hand or the arm, an action of squeezing the hand, or the like) in the case of motion recognition, and an action of speaking a specific word (‘next’, or the like) in the case of speech recognition. However, the preset user motion is not limited thereto, but may include user motions in various forms for displaying the second UI. In this case, the remote control apparatus may include a sensor for sensing that the user shakes or overturns the remote control apparatus. 
     Here, the second UI includes UI elements different from at least one of one or more UI elements included in the first UI. For example, in the case in which the first UI includes a first element, a second element, a third element, and a fourth element, a newly displayed second UI may include a fifth element, a sixth element, a seventh element, and an eighth element. In addition, in the case in which the first UI includes a first element, a second element, a third element, and a fourth element, only some of the elements displayed in the first UI may be changed, such that a newly displayed second UI may include the second element, the third element, the fourth element, and a fifth element. 
     Meanwhile, the control unit  130  may control the display unit  110  to display the second UI at the same position as a position at which the first UI is displayed. 
     Meanwhile, the control unit  130  may control the display unit  110  to display the first UI including different UI elements depending on a currently displayed image. 
     For example, in the case in which television (TV) broadcasting is currently displayed on the display unit  110 , when the UI generating command of the user is input, the control unit  130  may control the display unit  110  to display the first UI including elements corresponding to functions (for example, setting, a channel list, a recently viewed channel, and volume adjustment) required during a period in which the TV broadcasting is viewed. In addition, in the case in which a VOD is currently played on the display unit  110 , when the UI generating command of the user is input, the control unit  130  may control the display unit  110  to display the first UI including elements corresponding to functions (for example, play-back, a channel list, a recently viewed channel, and volume adjustment) required during a period in which the VOD is played. 
     Meanwhile, similar to the first UI, the second UI may be displayed on the display unit  110  so as to include different UI elements depending on a currently displayed image by a control of the control unit  130 . 
     Meanwhile, the control unit  130  may control the display unit  110  to change the first UI into the second UI and display the second UI by an animation effect in a scheme corresponding to a preset user motion. In detail, the control unit  130  may set an animation effect in a scheme corresponding to each of specific motions of the user, and control the display unit  110  to change the first UI into the second UI and display the second UI while displaying an animation effect corresponding to a specific motion of the user when the specific motion of the user is present. 
     Meanwhile, the control unit  130  may control the display unit  110  to display the first UI including UI elements set to be preferentially displayed depending on a currently displayed image. 
     In detail, the control unit  130  may set priorities for UI elements that may be displayed in the currently displayed image using a preset reference and control the display unit  110  to display the first UI including the UI elements having the highest priority. 
     Here, the preset reference may be set depending on whether a function is a function that the user most frequently uses for the currently displayed image or is a function that has a slightly low use frequency, but causes inconvenience of the user when it is not displayed. 
     In addition, the priorities for the UI elements may also be changed by setting of the user. 
     Meanwhile, in the case in which the preset user motion is input, the control unit  130  may control the display unit  110  to display the second UI including UI elements set to be displayed subsequently to the UI elements set to be preferentially displayed. 
     For example, when UI elements corresponding to a channel switching function, a volume adjusting function, a function of moving to the most recently viewed channel, and a channel list searching function having the highest priority are included in the first UI and are displayed and functions having the second highest priority are a setting function, a broadcasting information searching function, a bookmark broadcasting searching function, and a video call function, the control unit  130  may control the display unit  110  to display the second UI including UI elements corresponding to the setting function, the broadcasting information searching function, the bookmark broadcasting searching function, and the video call function. 
     Meanwhile, the display apparatus  100  may include a sensor unit (not illustrated) for sensing a motion or a speech of the user. 
       FIG. 2  is a view illustrating UIs or GUIs differently displayed depending on various TV control schemes according to the related art. 
     In  FIG. 2 , a display screen  210  in which a menu UI at the time of controlling a TV by motion recognition is displayed, a display screen  220  in which a menu UI at the time of controlling a TV by speech recognition is displayed, a display screen  230  in which a menu UI at the time of controlling a TV by a pointer is displayed, and a display screen  240  in which a menu UI at the time of controlling a TV by a remote controller including four-direction buttons is displayed are illustrated. 
     As illustrated in  FIG. 2 , according to the related art, since displaying methods of the menu UI are different from each other depending on the respective control schemes, new learning and experience for each of various control schemes were previously required in order for the user to be accustomed to a new control scheme. 
       FIGS. 3A and 3B  are views illustrating a UI consistently that may be standardized and displayed regardless of a plurality of control schemes according to an exemplary embodiment. 
     As illustrated in  FIGS. 3A and 3B , when the UI generating command of the user is input through the input unit  120 , the control unit  130  may control the display unit  110  to display a first UI  310  or GUI. 
     In this case, the first UI  310  (see  FIG. 3A ) may include UI elements  311  to  314  (or controls/widgets) that may be controlled in a plurality of control schemes. 
     A GUI control or a widget is an element of interaction in a graphical user interface (GUI), like a button or a scroll bar. Controls are software components that a computer user interacts with through direct manipulation to read or edit information or to activate functions or other elements like menus. 
     In addition, the UI elements  311  to  314  included in the first UI  310  may be included in an upper region, a lower region, a left region, and a right region divided from a region of the first UI  310 , respectively. 
     Meanwhile, a second UI (not illustrated) may also be displayed in the same form as a form of the first UI  310 , but may be displayed so as to include UI elements different from the UI elements included in the first UI  310 . 
     However, although the case in which the first UI  310  includes four UI elements has been described in the present exemplary embodiment, the first UI  310  is not limited to including the four UI elements. That is, the first UI  310  may include one or more UI elements. 
     In addition, although the case in which the UI elements  311  to  314  are included in the upper region, the lower region, the left region, and the right region divided from the region of the first UI  310 , respectively, has been described in the present exemplary embodiment, the UI elements are not limited to being included in these regions. For example, the UI elements  311  to  314  may also be implemented so as to be included in a right upper region, a right lower region, a left upper region, and a left lower region divided from the region of the first UI  310 , respectively. 
     The shape of the UI elements in  FIG. 3A  is a chevron or “V” like shape. 
       FIG. 3B  shows another version of the GUI  320  that can be consistently used or standardized over different interaction method where a shape of the UI elements or controls  321 - 324  is like an arrow. In the control GUI of  FIG. 3B  when the user activates one of the controls, such as control  312 , a second menu “Menu 2” from among “Menu 1”-“Menu 4” is activated. When the user touches the touch panel of the remote control apparatus in the specific direction of control  312 , the control unit  130  may recognize that the UI element or control corresponding to the direction corresponding to this user command is selected (in this example the function of “Menu 2” and execute a function to display “menu 2”). 
     As described above, the UI may be standardized and consistently used regardless of control schemes of the TV by the user is provided, thereby making it possible to decrease necessity for learning of the user and improve basic usability of the TV. 
     In addition, a four-direction control scheme that is most or often familiar to the user regardless of control schemes of the TV by the user is provided, thereby making it possible to induce convenient use by the user. 
       FIGS. 4A to 4C  are views illustrating a displaying method of a first UI or GUI according to an exemplary embodiment. 
       FIG. 4A  is a view illustrating that when a UI generating command is input during a period in which a highlight  420  is displayed on a screen  410  of the display unit  110 , a first UI  430  is displayed in the vicinity of a menu item in which the highlight is displayed. 
     When the user manipulates a direction using the remote control apparatus to take a specific motion or speak a specific word, thereby performing a manipulation of moving between a plurality of menu items, the control unit  130  may control the display unit  110  to display the vicinity of a menu item to which the user wants to move as a highlight  420 . In this case, when the user inputs a manipulation for generating the first UI  430 , the control unit  130  may control the display unit  110  to display the first UI  430  in the vicinity of the menu item in which the highlight  420  is displayed. The highlight may be a thick border as shown or a change of color, etc. 
     In this case, UI elements included in the first UI  430  may be UI elements corresponding to functions related to a menu item in which the highlight  420  is displayed. For example, when a plurality of menu items showing a current channel list are displayed and the highlight  420  is displayed in a specific channel, UI elements corresponding to a function of playing a specific channel in which the highlight is displayed, a function of deleting the specific channel in which the highlight is displayed, a function of registering the specific channel in which the highlight is displayed as a preference channel, and a function of moving to the next menu item may be included in the first UI  430 . 
       FIG. 4B  is a view illustrating that when a UI generating command is input during a period in which a pointer  440  is displayed on the screen  410  of the display unit  110 , the pointer  440  is changed into a first UI  430  and the first UI  430  is displayed. 
     In detail, the control unit  130  may control the display unit  110  to display the pointer  440  moving in a direction corresponding to a direction manipulation of the user on the screen  410  of the display unit  110 . In this case, when the user inputs a manipulation for generating the first UI  430 , the control unit  130  may control the display unit  110  to change the pointer  440  into the first UI  430  and display the first UI  430 . 
     As described above, the UI is not displayed in a fixed region, but is displayed in the vicinity of a focus of the user (such as the pointer  440 ), thereby making it possible to induce convenient use of the user. 
       FIG. 4C  is a view illustrating that a first UI  430  is displayed in the case in which the pointer or the highlight is not displayed on the screen  410  of the display unit  110 . 
     In detail, when the user performs a specific manipulation for the remote control apparatus or inputs a specific motion or a specific speech through the input unit  120 , the control unit  130  may control the display unit  110  to display the first UI  430  on a specific region of the screen  410  of the display unit  110 . 
       FIGS. 5A to 5D  are views illustrating a selecting method of a UI element or GUI included in the first UI according to an exemplary embodiment. 
     As illustrated in  FIG. 5A , when the user selects a direction key of a specific direction of a remote control apparatus, the control unit  130  may recognize that a UI element  532  of a direction corresponding to a user command is selected and execute a function corresponding to the selected UI element. 
     For example, a first UI  530  may include a first UI element  531 , a second UI element  532 , a third UI element  533 , and a fourth UI element  534 . In this case, when the user selects a direction key  541  of a right direction, the control unit  130  may recognize that a UI element  532  of the right direction, which is a direction corresponding to a user command, is selected and execute a function corresponding to the selected UI element  532 . In this case, when the function corresponding to the selected UI element  532  is ‘volume adjustment’, the control unit  130  may control the display apparatus  100  to perform a volume adjusting function. 
     As illustrated in  FIG. 5B , when the user moves a pointer  550  in a specific direction using a remote control apparatus  560  having a pointing function, the control unit  130  may recognize that a UI element  532  of a direction corresponding to a user command is selected and execute a function corresponding to the selected UI element  532 . 
     For example, when the user moves the pointer  550  in a right direction, the control unit  130  may recognize that the UI element  532  of the right direction, which is a direction corresponding to a user command, is selected and execute a function corresponding to the selected UI element  532 . 
     In this case, when the pointer  550  moves to a region in which UI elements  531  to  534  are positioned, the control unit  130  may recognize that the UI elements are selected. In addition, when the pointer  550  moves to the region in which UI elements  531  to  534  are positioned and the user additionally inputs a specific manipulation such as a manipulation of pressing a button, or the like, the control unit  130  may also be implemented to recognize that the input UI element is selected. 
     Meanwhile, although the case in which the pointer  550  is displayed on a screen of the display unit  110  has been described in the present exemplary embodiment and is not limited thereto. That is, the control unit  130  may recognize that the UI element is selected by only recognizing a movement direction of the pointer of the user without displaying the pointer  550 . 
     As illustrated in  FIG. 5C , when the user inputs a touch motion in a specific direction on a touch panel  571  using a remote control apparatus  570  including the touch panel  571 , the control unit  130  may recognize that a UI element  532  of a direction corresponding to a user command is selected and execute a function corresponding to the selected UI element. 
     For example, when the user inputs a touch of a right direction to the touch panel  571 , the control unit  130  may recognize that the UI element  532  of the right direction, which is a direction corresponding to a user command, is selected and execute a function corresponding to the selected UI element  532 . 
     As illustrated in  FIG. 5D , in the case of a display apparatus providing a motion recognizing function, when the user takes a motion of moving his/her hand, arm, or the like, in a specific direction, the control unit  130  may recognize that a UI element of a direction corresponding to a user command is selected and execute a function corresponding to the selected UI element. 
     For example, when the user takes a motion of moving his/her hand, arm, or the like, from a left direction to a right direction, the control unit  130  may recognize that the UI element  532  of the right direction, which is a direction corresponding to a user command, is selected and execute a function corresponding to the selected UI element  532 . 
     Meanwhile, although not illustrated, in the case of a display apparatus providing a speech recognizing function, when the user inputs a word representing a specific direction, the control unit  130  may recognize that a UI element of a direction corresponding to a user command is selected and execute a function corresponding to the selected UI element. 
     For example, when the user inputs or speaks a word ‘right’, the control unit  130  may recognize that the UI element  532  of a right direction, which is a direction corresponding to a user command, is selected and execute a function corresponding to the selected UI element  532 . 
     The user may also speak the name of the item such as “menu 2” as shown in  FIG. 5D . 
     Meanwhile, although a description has been provided in relation to the first UI in  FIGS. 5A to 5D , UI elements included in a second UI may be selected by a method similar to a method of selecting the UI elements included in the first UI. 
       FIG. 6  is a view illustrating a region in which a pointer moves in the case in which a UI or GUI is displayed, according to an exemplary embodiment. 
     As illustrated in  FIG. 6 , generally, a pointer  640  displayed on a screen  610  of the display unit  110  may move over the entirety of the screen  610  of the display unit  110  depending on a manipulation of the user. However, in the case in which a first UI  630  or a second UI (not illustrated) is displayed, the control unit  130  may control the pointer  640  to move only within a specific region  650 . In this case, a region in which the first UI  630  is displayed and the specific region  650  may coincide with each other. 
     As described above, a region in which the pointer  640  may move is limited to the specific region  650 , thereby making it possible to facilitate a pointing manipulation of the user for selecting the UI element. 
       FIG. 7  is a view illustrating a second UI in which sub-UI elements of a UI element selected by a user are displayed, according to an exemplary embodiment. 
     As illustrated in  FIG. 7 , when a UI element or GUI of a direction corresponding to a user command among UI elements  731  to  734  included in a first UI  730  is selected, the control unit  130  may control the display unit  110  to display a second UI  750 . In this case, the second UI  750  may include UI elements  751  to  754  corresponding to sub-functions of a function of the selected element. 
     That is, the UI or GUI is standardized across interactions when the first UI or GUI  730  is changed to the second UI or GUI  750 . 
     For example, when the user selects a UI element  732  of a right direction and a function corresponding to the selected UI element  732  is volume adjustment, a newly displayed second UI  750  may include UI elements  751  to  754  corresponding to sub-functions (for example, volume-up (by one step), volume-down (by one step), volume-up (by three steps), and volume-down (by three steps)) of the volume adjusting function. 
     In this case, the user may select the UI elements  751  to  754  in the second UI  750  by a process similar to a process of selecting the UI elements  731  to  734  in the first UI  730 . 
     Meanwhile, the second UI element may be positioned in the same region as a region in which the first UI element is positioned, on the screen of the display unit  110 , but is not limited thereto. For example, in the case in which a specific UI element is selected using the pointer, the control unit  130  may control the display unit  110  to display the second UI based on a position of the selected UI element. 
       FIG. 8  is a view illustrating that a UI element or GUI is included and displayed in first and second UIs depending on a priority, according to an exemplary embodiment. 
     As illustrated in  FIG. 8 , in the case in which a preset user motion is input through the input unit, the control unit  130  may control the display unit  110  to display a second UI including UI elements different from at least one of one or more UI elements included in a first UI. A detailed description for the preset user motion will be provided below with reference to  FIGS. 9A to 9D . 
     Here, the second UI  840  includes UI elements different from at least one of one or more UI elements included in the first UI  830 . For example, in the case in which the first UI  830  includes a first element  831 , a second element  831 , a third element  833 , and a fourth element  834 , a newly displayed second UI  840  may include a fifth element  841 , a sixth element  842 , a seventh element  843 , and an eighth element  844 . 
     However, the embodiments are not limited thereto, but may also be implemented in a scheme of displaying a second UI in which only some of the elements displayed in the first UI are changed. For example, in the case in which the first UI includes a first element, a second element, a third element, and a fourth element, only some of the elements displayed in the first UI may be changed, such that a newly displayed second UI may include the second element, the third element, the fourth element, and a fifth element. 
     Meanwhile, as illustrated in  FIG. 8 , the control unit  130  may control the display unit  110  to display the first UI  830  including UI elements  831  to  834  set to be preferentially displayed depending on a currently displayed image. 
     In detail, the control unit  130  may set priorities for UI elements that may be displayed in the currently displayed image using a preset reference and control the display unit  110  to display the first UI including the UI elements having the highest priority. 
     For example, in the case in which TV broadcasting is currently displayed on the screen of the display unit  110 , the control unit  130  may set priorities for functions (a channel switching function, a volume adjusting function, a function of moving to the most recently viewed channel, a setting function, a channel list searching function, a broadcasting information searching function, a bookmark broadcasting searching function, a video call function, and the like) required in the case in which the TV broadcasting is displayed depending on the preset reference. In addition, when the channel switching function, the volume adjusting function, the function of moving to the most recently viewed channel, and the channel list searching function have the highest priority, the control unit  130  may control the display unit  110  to display the first UI  830  including the UI elements  831  to  834  corresponding to the channel switching function, the volume adjusting function, the function of moving to the most recently viewed channel, and the channel list searching function. 
     Meanwhile, in the case in which the preset user motion is input, the control unit  130  may control the display unit  110  to display the second UI  840  including UI elements  841  to  844  set to be displayed subsequently to the UI elements  831  to  834  set to be preferentially displayed. 
     For example, when the UI elements  831  to  834  corresponding to the channel switching function, the volume adjusting function, the function of moving to the most recently viewed channel, and the channel list searching function having the highest priority are included in the first UI  830  and are displayed and functions having the second highest priority are the setting function, the broadcasting information searching function, the bookmark broadcasting searching function, and the video call function, the control unit  130  may control the display unit  110  to display the second UI  840  including the UI elements  841  to  844  corresponding to the setting function, the broadcasting information searching function, the bookmark broadcasting searching function, and the video call function. 
     Meanwhile, although the case in which only the UIs up to the second UI  840  are displayed has been described in the present exemplary embodiment, is not limited thereto. For example, in the case in which the preset user motion is input in a state in which the second UI  840  is displayed, the control unit  130  may control the display unit to change the second UI  840  into a third UI (not illustrated) and display the third UI. In this case, the control unit  130  may control the display unit  110  to display the third UI including UI elements (not illustrated) set to be displayed subsequently to the UI elements  841  to  844  displayed in the second UI  840 . 
       FIGS. 9A to 9D  are views that a first UI is changed into a second UI or GUI and the second UI or GUI is displayed depending on a user motion, according to an exemplary embodiment. 
     As illustrated in  FIGS. 9A to 9D , in the case in which a preset user motion is input through the input unit  120 , the control unit  130  may control the display unit  110  to display a second UI  940  including UI elements  941  to  944  different from at least one of one or more UI elements  931  to  934  included in a first UI  930 . 
     As illustrated in  FIG. 9A , the preset user motion may be an action of pressing a specific button of a remote control apparatus  950 . In detail, when the user presses a confirmation button  951  of the remote control apparatus  950 , this user input may be input through the input unit  120 , and the control unit  130  may control the display unit  110  to display the second UI  940  including the UI elements  941  to  944  different from at least one of one or more UI elements  931  to  934  included in the first UI  930 . 
     As illustrated in  FIG. 9B , the preset user motion may be an action of shaking the remote control apparatus  950 . In detail, when the user shakes the remote control apparatus  950 , this user input may be input through the input unit  120 , and the control unit  130  may control the display unit  110  to display the second UI  940  instead of the first UI  930 . 
     As illustrated in  FIG. 9C , the preset user motion may be a specific motion (an action of overturning a hand or an arm) of the user. In detail, when the user overturns his/her hand or arm, this user input may be input through the input unit  120 , and the control unit  130  may control the display unit  110  to display the second UI  940  instead of the first UI  930 . 
     As illustrated in  FIG. 9D , the preset user motion may be a specific motion (an action of squeezing a hand) of the user. In detail, when the user squeezes his/her hand, this user input may be input through the input unit  120 , and the control unit  130  may control the display unit  110  to display the second UI  940  instead of the first UI  930 . 
     Meanwhile, the preset user motion is not limited to those of the above-mentioned exemplary embodiments. That is, various user motions of allowing the second UI  940  including the UI elements  941  to  944  different from at least one of one or more UI elements  931  to  934  included in the first UI  930  to be displayed may be present. For example, the preset user motion may be an action of overturning the remote control apparatus, a specific pointing action using the remote control apparatus, a specific action (an action of pressing a touch pad or simultaneously pressing two points, or the like) using the touch panel of the remote control apparatus, a specific motion (an action of shaking a hand or an arm, or the like) in the case of motion recognition, and an action of speaking a specific word (“next”, or the like) in the case of speech recognition. 
     Meanwhile, the display apparatus  100  may include a sensor unit (not illustrated) for recognizing a motion or a speech of the user. 
     In addition, the remote control apparatus  950  may include a sensor (not illustrated) for sensing a user action of shaking or overturning the remote control apparatus. 
     As described above, the second UI including the UI elements different from those of the first UI is displayed in response to the preset motion of the user, thereby making it possible to allow a function desired by the user to be easily searched while maintaining the four-direction control scheme. 
       FIGS. 10A to 10C  are views that a first UI is changed into a second UI and the second UI is displayed using an animation effect, such as a fade-out to fade-in in a scheme corresponding to a preset user motion, according to an exemplary embodiment. 
     As illustrated in  FIGS. 10A to 10C , the control unit  130  may control the display unit  110  to change the first UI into the second UI and display the second UI by an animation effect in a scheme corresponding to a preset user motion. 
     In detail, the control unit  130  may set an animation effect in a scheme corresponding to each of specific motions of the user, and control the display unit  110  to change the first UI into the second UI and display the second UI while displaying an animation effect corresponding to a specific motion of the user when the specific motion of the user is present. 
     As illustrated in  FIG. 10A , the control unit  130  may control the display unit  110  to display an animation effect that UI elements  1031  to  1034  included in a first UI  1030  are dispersed depending on a user motion of shaking a remote control apparatus and display a second UI  1040  including new UI elements  1041  to  1044  at a position at which the first UI  1030  was displayed. 
     In addition, although not illustrated, the control unit  130  may control the display unit  110  to display an animation effect that the first UI  1030  is shaken depending on a user motion of shaking the remote control apparatus and display the second UI  1040  at a position at which the first UI  1030  in a stop state was displayed. 
     In addition, although not illustrated, in the case of a control using motion recognition of the user, the control unit  130  may control the display unit  110  to display an animation effect that the UI elements  1031  to  1034  included in the first UI  1030  are dispersed depending on a user motion of shaking the hand, the arm, or the like, and display the second UI  1040  including the new UI elements  1041  to  1044  at the position at which the first UI  1030  was displayed. 
     As illustrated in  FIG. 10B , the control unit  130  may control the display unit  110  to display an animation effect that a first UI  1030  is overturned or turned around depending on a user motion of overturning the remote control apparatus or hand and display a second UI  1040  at a position at which the first UI  1030  in a stop state was displayed. In this case, the control unit  130  may control the display unit  110  to display an animation effect that the first UI  1030  is overturned or reversed in a direction in which the user overturns the remote control apparatus or the hand. 
     In addition, although not illustrated, in the case of the control using the motion recognition of the user, the control unit  130  may control the display unit  110  to display an animation effect that the first UI  1030  is overturned depending on a user motion of shaking the hand, the arm, or the like, and display the second UI  1040  at a position at which the first UI  1030  in a stop state was displayed. In this case, the control unit  130  may control the display unit  110  to display an animation effect that the first UI  1030  is overturned in a direction in which the user overturns his/her hand or arm. 
     In addition, although not illustrated, in a case of a control using speech recognition of the user, the control unit  130  may control the display unit  110  to change the first UI  1030  into the second UI  1040  and display the second UI  1040  by an animation effect corresponding to an input of a word ‘shaking’, ‘overturning’, or the like, by the user. 
     As illustrated in  FIG. 100 , in the case of the control using the motion recognition of the user, the control unit  130  may control the display unit  110  to display an animation or transition effect that a standardized first UI  1030  is crumpled or otherwise distorted depending on a user motion of squeezing a hand and display a standardized second UI  1040  at a position at which the first UI  1030  was displayed while displaying an animation effect that the second UI  1040  that was crumpled is uncrumpled. 
     Meanwhile, the embodiments are not limited to the above-mentioned exemplary embodiment. That is, the control unit  130  may set an animation effect in a scheme corresponding to each of a specific action using a pointer, a specific action using a touch panel, an action of pressing a specific button, a specific motion, and a specific speech and control the display unit  110  to display an animation effect corresponding to the specific motion of the user when the specific motion of the user is present, change the first UI into the second UI, and display the second UI. 
     As described above, a UI menu is changed by the animation effect corresponding to a motion of the user, thereby making it possible to generate a user&#39;s interest. 
       FIGS. 11A to 11C  are views illustrating that a UI or GUI including different UI elements is displayed depending on a currently displayed image, according to an exemplary embodiment. 
     As illustrated in  FIGS. 11A to 11C , the control unit  130  may control the display unit  110  to display a first UI including different UI elements depending on a currently displayed image. 
     TV broadcasting is currently displayed on a screen  1110  of the display unit  110  in  FIG. 11A . In this case, the control unit  130  may control the display unit  110  to display a first UI or GUI  1130  including elements  1131  to  1134  corresponding to functions (for example, setting, a channel list, a recently viewed channel, and volume adjustment) required during a period in which the TV broadcasting is viewed. 
     VOD is currently played on a screen  1110  of the display unit  110  in  FIG. 11B . In this case, the control unit  130  may control the display unit  110  to display a first UI  1130 ′ including elements  1131 ′ to  1134 ′ corresponding to functions (for example, play-back, a channel list, a recently viewed channel, and volume adjustment) required during a period in which the VOD is played. 
     Various menu items that may be selected by the user are currently displayed on a screen  1110  of the display unit  110  in  FIG. 11C . In this case, the control unit  130  may control the display unit  110  to display a first UI or GUI  1130 ″ including elements  1131 ″ to  1134 ″ corresponding to functions (for example, play, deletion from a menu list, movement of a highlight, registration as a preferring menu) that may be performed. 
     Meanwhile, similar to the standardized first UI or GUI, the second standardized UI or GUI may be displayed on the display unit  110  so as to include different UI elements depending on a currently displayed image by a control of the control unit  130 . For example, in the case in which the VOD is currently played on the screen  1110  of the display unit  110  and the first UI or GUI  1130 ′ including the elements  1131 ′ to  1134 ′ corresponding to the functions (for example, the play-back, the channel list, the recently viewed channel, and the volume adjustment) required during the period in which the VOD is played is displayed, the control unit  130  may control the display unit  110  to display a second UI including elements corresponding to functions (for example, pause, fast winding, rewinding, and stop) required during the period in which the VOD is played when a preset user motion is input. 
     As described above, the UIs are differently displayed depending on the currently displayed image, thereby making it possible to induce convenient use of the user. 
       FIG. 12  is a view illustrating that a UI displayed on a screen of a TV disappears, according to an exemplary embodiment. 
     As illustrated in  FIG. 12 , when the user does not input any command during or for a preset time or performs the same manipulation as a manipulation performed while inputting a UI generating command, the control unit  130  may control the display unit  110  so that a first UI  1230  or a second UI (not illustrated) displayed on a screen  1210  of the display unit  110  disappears. An animation effect, such as a fade-out may be used in the disappearance. 
       FIG. 13  is a block diagram illustrating a configuration of a display apparatus according to another exemplary embodiment. 
     As illustrated in  FIG. 13 , the display apparatus  1300  may include an image input unit  1310 , an image processing unit  1320 , an audio processing unit  1330 , a storing unit  1340 , a display unit  1350 , an audio output unit  1360 , a communicating unit  1370 , an input unit  1380 , and a control unit  1390  which may comprise a processor or computer. 
     The image input unit  1310  may receive image data through various sources.

     Referring to  FIG. 14 , first, in the case in which a UI or GUI generating command is input, a standardized first UI or GUI including one or more UI elements controllable in a plurality of control schemes is displayed (S 1410 ). 
     In detail, when the user presses a specific button of the remote control apparatus, takes a specific pointing action using the remote control apparatus, takes a specific action using the touch panel included in the remote control apparatus, takes a specific motion, or speaks a specific word, it may be recognized that the UI generating common is input, and the first UI may be displayed. 
     In addition, the first UI may include UI elements corresponding to the respective functions of the display apparatus. For example, the first UI may include one or more of a UI element corresponding to a volume adjusting function, a UI element corresponding to a setting function, a UI element corresponding to a channel list searching function, and a UI element corresponding to a recently viewed channel searching function. 
     In addition, the user may control the UI elements in a plurality of control schemes. In detail, the user may select the UI elements using at least one of a control scheme using direction keys of the remote control apparatus, a control scheme using a pointing motion of the remote control apparatus, a control scheme using the touch panel included in the remote control apparatus, a control scheme using a photographed user motion, and a control scheme using a user speech. 
     Meanwhile, in the case in which or when a preset user motion is input, a standardized second UI or GUI including UI elements different from at least one of the one or more UI elements is displayed (S 1420 ). 
     Here, the preset user motion may be an action of pressing a specific button of the remote control apparatus, an action of shaking the remote control apparatus, an action of overturning the remote control apparatus, a specific pointing action using the remote control apparatus, a specific action (an action of pressing a touch pad, an action of simultaneously pressing two points, or the like) using the touch panel of the remote control apparatus, a specific motion (an action of shaking a hand or an arm, an action of overturning the hand, the arm, or the like, an action of squeezing the hand, or the like) in the case of motion recognition, and an action of speaking a specific word (“next”, or the like) in the case of speech recognition. However, the preset user motion is not limited thereto, but may include user motions in various forms for displaying the second UI. 
     Meanwhile, the second UI includes UI elements different from at least one of one or more UI elements included in the first UI. For example, in the case in which the first UI includes a first element, a second element, a third element, and a fourth element, a newly displayed second UI may include a fifth element, a sixth element, a seventh element, and an eighth element. In addition, in the case in which the first UI includes a first element, a second element, a third element, and a fourth element, only some of the elements displayed in the first UI may be changed, such that a newly displayed second UI may include the second element, the third element, the fourth element, and a fifth element.
