For example, in the case an item indicates an application, the display apparatus  100  may control the item displayed and/or may control the application itself based on the input from the control device  200   c  using the direction key and the touch pad. 
     As shown in  FIG. 1A , the display apparatus  100  may be controlled by a plurality of control devices  200   a ,  200   b ,  200   c ,  200   d ,  200   e  which are different from each other, and forms of objects displayed on the display apparatus  100  in response to an indication of an input from each control device may be different. 
       FIG. 1B  is a reference diagram illustrating a display apparatus operating in a focusing mode according to an exemplary embodiment. A focusing mode may be referred to as a navigation mode or a menu driven mode. 
     Referring the  FIG. 1B , the display apparatus  100  may select, move, or scroll the items displayed in the item region  300  based on receipt of an indication of the input of the direction key provided in the control device  200 . The scrolling denotes an operation of vertically or horizontally sliding a text, an image, or a video displayed on a computer display, a monitor, or a display of a television. The scrolling may be an operation of moving a view of a user to show a portion of an image which is not displayed entirely without changing a layout of the text or the image. 
     According to an exemplary embodiment, when initially sensing input from the user using direction keys  201  or  204  provided respectively in the control device  200   a  and  200   c , the display apparatus  100  may initialize an operation for controlling the item according to the input of the direction key, and display a specific item by adding, according to an algorithm, a visual effect, which indicates that the specific item that is focused on, to the specific item. For example, when initially receiving the indication of the input of the direction keys provided in the control device  200   a  or  200   c , the display apparatus  100  may display a first item  3  by adding a focus visual effect  310  to the item  3  displayed in the item region. The algorithm—in this case the focus visual effect algorithm—may be predetermined. In some exemplary embodiments, the algorithm may be set by the manufacturer or the user. 
     According to an exemplary embodiment, the focus visual effect may include displaying a focused item by surrounding a border of the focused item with a bold line. 
     According to other exemplary embodiments, the focus visual effect may include using a different color for the focused item, or using different transparency for the focused item. 
     According to another exemplary embodiment, the focus visual effect may include using a different size for the focused item. 
     According to another exemplary embodiment, the focus visual effect may include generating an interval between the focused item and other items. 
     According to another exemplary embodiment, when sensing the input from the user using the direction key provided in the control device  200   a  or  200   c  in a state in which a specific item is focused, the display apparatus  100  may move the focus visual effect  310  to an adjacent item corresponding to the input of the direction key. 
     For example, when receiving an indication of the input of a right direction key from the control device  200   a  or  200   c  in a state in which the item  3  is focused, the display apparatus  100  may display the item  4  by moving the focus visual effect added to the item  3  to the item  4  adjacent in a right direction of the item  3 . It will be understood that when the focus visual effect is moved and added to item  4 , the focus visual effect added to item  3  is removed. However, in some exemplary embodiments, it may be possible to add the focus visual effect to item  4  while maintaining the focus visual effect on item  3 , for example in a case of selecting two items to interact together. 
     For example, when receiving an indication of the input of a left direction key from the control devices  200   a  or  200   c  in the state in which the item  3  is focused, the display apparatus  100  may display the item  2  by moving the focus visual effect added to the item  3  to the item  2  adjacent in a left direction of the item  3 . It will be understood that when the focus visual effect is moved and added to item  2 , the focus visual effect added to item  3  is removed. However, in some exemplary embodiments, it may be possible to add the focus visual effect to item  2  while maintaining the focus visual effect on item  3 , for example in a case of selecting two items to interact together 
     According to an exemplary embodiment, the display apparatus  100  may control the items in the item region based on the pointing input of the control device  200 . 
       FIG. 1C  is a reference diagram illustrating a display apparatus operating in a pointing mode according to an exemplary embodiment. 
     Referring to  FIG. 1C , a cursor  320  may be displayed on a screen of the display  115  in response to the pointing position of the control device  200 . 
     An example in which the cursor has a circular shape is illustrated in  FIG. 1C , but the shape is not particularly limited and the cursor may have various shapes. The cursor  320  refers to an indicator used for showing a position in a computer monitor or the display in response to input of a text or the pointing device in a computing device. The indicator used for showing the position on the display in response to receiving the input from the pointing device such as a mouse, etc. may be mainly referred to as a pointer. Referring to  FIG. 1C , when the user moves the control device  200   c  to point toward the screen of the display  115 , the display apparatus  100  may be initialized to operate in a pointing mode and the cursor  320  may be displayed on the screen of the display  115  in response to a position indicated by the control device  200   c . For example, a motion sensor that may be provided in the control device  200   c  may sense the movement of the control device  200   c  by the user, and may transmit the motion to the display apparatus  100  and the display apparatus  100  may control the display to accordingly move the cursor  320  on the screen. Alternatively, in some exemplary embodiments, the user may move the cursor  320  using a touch pad of the control device  200 . 
     For example, when receiving a signal generated when a finger of the user has touched a touch pad  203  provided in the middle of the control device  200   c  implemented as the pointing device, the display apparatus  100  may be initialized to operate in a pointing mode, and display the cursor  320  on the display  115 . When the user moves the control device  200   c  in a state in which the finger touches the touch pad  203 , a motion sensor (an accelerator sensor, a gyro sensor) provided in the control device may sense a motion of the control device, and output a value of the motion sensor corresponding to the sensed motion, and a controller  280  (see, e.g.,  FIG. 4A ) of the control device may control a communicator  220  to transmit the value of the motion sensor to the display apparatus  100 . The display apparatus  100  may display the cursor  320  on the display  115  by determining a position of the cursor  320  based on the received value of the motion sensor. Further, for example, when pushing the touch pad  203  of the control device  200   c  using the finger in a manner of pushing a normal button, a switch provided below the touch pad may be operated and used as an input unit for selecting a specific item. 
     Further, when the control device  200   c  indicates one of the items in the item region  300 , the display apparatus  100  may display a corresponding item in a rollover state. When the cursor  320  is located on the item, the display apparatus  100  may add a visual effect to a corresponding item in which the cursor is located similar to the focus visual effect, and when the cursor departs the item by being moved again, the display apparatus  100  may remove the focus visual effect in order to restore the item to its original display configuration. 
     Moreover, the control device  200   d  serving as the pointing function may be implemented without the touch pad. For example, the pointing device may be implemented so that the value of the motion sensor corresponding to the motion of the control device  200  is output only by an operation in which the user grips and moves the control device  200   d.    
     As such, as shown in  FIG. 1B , when using the display apparatus in the focusing mode, the display apparatus  100  may display by adding the focus visual effect or a highlight effect to a selected item in order to indicate the selected item, and when using the display apparatus in the pointing mode, the display apparatus displays the cursor on the screen of the display. Accordingly, a method capable of providing intuitive and natural experiences to the user, such as how to process the cursor displayed in the pointing mode when the user wants to use the display apparatus in the focusing mode while using the display apparatus in the pointing mode, or whether to place the cursor initially displayed in the pointing mode at any place when the user wants to use the display apparatus in the pointing mode while using the display apparatus in the focusing mode may be provided. 
       FIG. 2  is a block diagram illustrating a display apparatus  100  according to an exemplary embodiment. 
     Referring to  FIG. 2 , the display apparatus  100  may include a display  115 , a controller  180 , and a sensor  160 . 
     The sensor  160  senses input from the control device  200 . 
     The sensor  160  according to an exemplary embodiment may sense the input of the control device to enable the display apparatus  100  to leave the pointing mode. 
     The sensor  160  according to another exemplary embodiment may sense the input of the control device to enable the display apparatus  100  to leave the focusing mode. 
     The display  115  may output the cursor on the screen in response to an indication of the input of the control device  200  used in the pointing mode according to the control of the controller  180 , and output the focus visual effect on the screen in response to the indication of the input of the control device  200  used in the focusing mode. 
     Further, the display  115  provides at least one item on the screen. 
     The display  115  according to an exemplary embodiment may move the cursor displayed on the display in the pointing mode onto the item which is focused on last in the focusing mode in response to the indication of the input of the control device to enable the display apparatus to leave the pointing mode according to the control of the controller  180 .

     The user input interface  230  may be configured as a keypad, a button, a touch pad, and/or a touch screen, etc. The user may input a command related to the display apparatus  100  to the control device  200  by manipulating the user input interface  230 . When the user input interface  230  includes a hard key button, the user may input a command related to the display apparatus  100  to the control device  200  through an operation of pushing the hard key button. When the user input interface  230  includes the touch screen, the user may input a command related to the display apparatus  100  to the control device  200  by touching a soft key of the touch screen. 
     For example, the user input interface  230  may include a four-directional button or a four-directional key  201  such as the control device  200   a  shown in  FIG. 1B  and  FIG. 4B . The four-directional button or four-directional key may be used for controlling a window, a region, an application, or an item displayed on the display  115 . The four-directional key or button may be used to direct movements in upward, downward, leftward, and rightward directions. Further, it may be understood that the user input interface  230  may include a two-directional key or a two-directional button instead of the four-directional key or the four-directional button. That is, the key or button arrangement is not particularly limited. 
     According to an exemplary embodiment, the four-directional button or the four-directional key  201  may be used for moving a focus of an item displayed in the item region provided in the display  115 . 
     Further, the user input interface  230  may include various kinds of input units, such as a scroll key or a jog key, etc., which may be manipulated by the user. 
     Moreover, the user input interface  230  may include a touch pad  202  such as that of the control device  200   b  shown in  FIG. 4B . According to an exemplary embodiment, the user input interface  230  may receive a user input of dragging, touching, or flipping through the touch pad of the control device  200 . Further, the display apparatus  100  may be controlled according to a kind of the received user input (for example, a direction in which a drag command is input, and a period in which a touch command is input). 
     Returning to  FIG. 4A , the sensor  240  may include a gyro sensor  241  or an acceleration sensor  243 . The gyro sensor  241  may sense information on a motion of the control device  200 . As an example, the gyro sensor  241  may sense the information on the motion of the control device  200  based on x, y, and z axes. The acceleration sensor  243  may sense information on a movement speed of the control device  200 . The sensor  240  may further include a distance measurement sensor, and sense a distance from the display apparatus  100  using the distance measurement sensor. 
     Referring to  FIG. 4B , the control device  200   c  according to an exemplary embodiment may be implemented as a pointing device including a four-directional key  204 , a touch pad  203 , a gyro sensor  241  (shown in  FIG. 4A ), and an acceleration sensor  242  (shown in  FIG. 4A ). That is, when the control device  200  is implemented as the pointing device, a function of the display apparatus  100  may be controlled according to a tilting direction or angle, etc. using the gyro sensor  241  of the control device  200 . 
     According to an exemplary embodiment, a selection signal of the four-directional key  204  may be used for moving a focus of an item displayed in the item region provided in the display  115 . 
     According to another exemplary embodiment, a touch signal of the touch pad  203  may be used for controlling a movement of a cursor provided in the display  115 . That is, when the touch signal of the touch pad  203  is used for controlling the movement of the cursor, the user may use a signal of the acceleration sensor or the gyro sensor of the pointing device  200   c  as an input signal for controlling the movement of the cursor by touching the touch pad  203  of the pointing device  200   c . Accordingly, the user may activate a pointing function of the pointing device  200   c  by touching the touch pad  203 , and deactivate the pointing function of the pointing device  200   c  by releasing the touch on the touch pad  203  of the pointing device  200   c.    
     Referring to  FIG. 4B , the control device  200   d  according to an exemplary embodiment may be implemented as a pointing device including a four-directional key  205 , a gyro sensor  241  (shown in  FIG. 4A ), and an acceleration sensor  242  (shown in  FIG. 4A ). The control device  200   d  may be similar to the control device  200   c , but may omit the touch pad  203 . Accordingly, the control device  200   d  may implement the pointing function without a touch to the touch pad. The user may activate the pointing function of the control device  200   d  by gripping and moving the control device  200   d , and deactivate the pointing function of the control device  200   d  by not moving the control device  200   d , or by putting down the control device  200   d  such that the control device  200   d  enters a power saving mode after a time has passed. The time may be predetermined. 
     Returning to  FIG. 4A , the output interface  250  may output an image or voice signal corresponding to the manipulation of the user input interface  230  or a signal received in the display apparatus  100 . The user may recognize whether the user input interface  230  is manipulated or the display apparatus  100  is controlled through the output interface  250 . 
     As an example, the output interface  250  may include an LED module  251  turned on or off when the user input interface  230  is manipulated or a signal is transceived with the display apparatus  100  through the wireless communicator  220 , a vibration module  253  generating a vibration, a sound output module  255  outputting a sound, or a display module  257  which outputs an image. 
     The power supply  260  may supply power to the control device  200 . The power supply  260  may reduce power consumption by stopping the supply of power when the control device  200  is not moved for a period of time. The period of time may be predetermined, or may be set by the manufacturer or the user. The power supply  260  may resume supplying the power when a key included in the control device  200  is manipulated. The key may be predetermined or may be set by the manufacturer or the user. 
     The storage  270  may store various kinds of programs, application data, etc. needed for a control or an operation of the control device  200 . 
     The controller  280  may control overall operations related to the control of the control device  200 . The controller  280  may transmit a signal corresponding to the manipulation of a key included in the user input interface  230  or a signal corresponding to the motion of the control device  200  sensed in the sensor  240  to the display apparatus  100  through the wireless communicator  220 . 
     The display apparatus  100  may include a coordinate value calculation unit (not shown) capable of calculating coordinate values of a cursor corresponding to the motion of the control device  200 . 
     The coordinate value calculation unit (not shown) may calculate the coordinate values (x, y) of the cursor displayed on the display  115  by correcting a vibration of a hand or an error from a signal corresponding to the motion of the control device  200  which is sensed. 
     Further, the transmission signal of the control device  200  sensed by the sensor  160  may be transmitted to the controller  180  of the display apparatus  100 . The controller  180  may determine information on the motion of the control device  200  and the manipulation of the key from the signal transmitted by the control device  200 , and may control the display apparatus  100  in response to the determined result. 
     As another example, the control device  200  may calculate the coordinate values of a cursor corresponding to the motion, and transmit the calculated result to the display apparatus  100 . In this case, the display apparatus  100  may transmit information on the received pointer coordinate values to the controller  180  without separately correcting the vibration of the hand or the error. 
     According to an exemplary embodiment, the user may control a position of the cursor or the focus displayed on the screen of the display using the direction key, the touch pad, the pointing function, etc. of the control device  200 , and select the item. 
       FIG. 5  is a flowchart for describing a display method in a display apparatus according to an exemplary embodiment. 
     Referring to  FIG. 5 , in operation S 510 , the display apparatus  100  displays on the display  115  at least one item controllable by at least one control device. 
     According to an exemplary embodiment, the display  115  may display the item as shown in  FIG. 6 . Referring to  FIG. 6 , the display apparatus  100  may provide an item region  600  for displaying items on the display  115 , and display items # 1  to # 6  in the item region  600 . Positions or the number of the item regions, and arrangements or the number of items may be diversely set, and be set according to methods described with reference to  FIGS. 1A to 1C . 
     The items displayed on the display  115  may be controlled according to a signal corresponding to the input of the direction key of the control device in the focusing mode, or be controlled according to a signal corresponding to the pointing function of the control device in the pointing mode as shown in  FIG. 6 . 
       FIG. 6  is a reference diagram for describing a display screen when a display apparatus is operated in a pointing mode according to an exemplary embodiment. 
     Referring to  FIG. 6 , the user may activate the pointing function of the control device  200   c  by touching the touch pad  203  of the control device  200   c  including the touch pad  203 . When the user moves the control device  200   c  in a state of touching the touch pad  203  of the control device  200   c , the gyro sensor  241  and the acceleration sensor  243  of the control device  200   c  sense the motion of the control device  200   c  and the control device  200   c  transmits the sensed movement signal to the display apparatus  100 , and the sensor  160  of the display apparatus  100  receives the movement signal and transmits the movement signal to the controller  180 . 
     The controller  180  which implements a display control function by loading the display control module  190 - 1  stored in the storage  190  places the cursor  320  in a position corresponding to the movement signal based on the movement signal transmitted from the sensor  160  by the pointing system  20 . 
     Alternatively, the user may activate the pointing function of the control device  200   d  by gripping and moving the control device  200   d  in which the touch pad is not included. 
     Returning to  FIG. 5 , in operation S 520 , the display apparatus  100  senses at least one input of the control device to enable the display apparatus to leave the pointing mode. 
     The input of the control device to enable the display apparatus to leave the pointing mode may include a deactivation action of the control device used in the pointing mode or an activation action of the control device used in the focusing mode. 
     The deactivation action of the control device used in the pointing mode may include a release of the touch in the control device used in the pointing mode or an entry of the power saving mode of the control device used in the pointing mode. 
       FIG. 7  is a reference diagram for describing an operation of a display apparatus according to input of a control device so that a display apparatus departs a pointing mode according to an exemplary embodiment. 
     Referring to  FIG. 7 , in a state in which a cursor  320  is placed at a position s(x1, y1) in the pointing mode, the user may deactivate the control device used in the pointing mode by moving fingers away from the touch pad  203  and releasing the touch, in the control device  200   c  in which the pointing function is implemented by including the touch pad  203 . 
     Alternatively, the control device  200   d  may enter the power saving mode when a period of time elapses without sensing the movement signal in the control device  200   d  when the user puts down the control device  200   d  in which the pointing function is implemented without including the touch pad. The period of time may be predetermined, or may be set by the manufacturer or the user. The entry of the power saving mode may be used as the deactivation action of the control device used in the pointing mode. 
     The activation action of the control device used in the focusing mode may include a signal corresponding to the input of the direction key by the user in the control device  200   a  including the direction key  201  as shown in  FIG. 7 . 
     The sensor  160  of the display apparatus  100  may sense the input of at least one control device to enable the display apparatus to leave the pointing mode, and transmit the sensed input to the controller  180 . 
     The pointing system  20  of the controller  180  may inform the integrated input device control system  40  of an event which indicates that there is a signal corresponding to the input of at least one control device to enable the display apparatus to leave the pointing mode as a type of an event. 
     Returning again to  FIG. 5 , in operation S 530 , the display apparatus  100  may move the cursor displayed on the display in the pointing mode onto the item which is focused on last in the pointing mode, in response to the sensed input. 
     The integrated input device control system  40  of the controller  180  which receives an event which indicates that there is a signal corresponding to the input of at least one control device to enable the display apparatus to leave the pointing mode may directly cause the cursor to disappear in the display  115 , and confirm information on the item which is lastly focused from the last focusing item information  12  stored in the focusing system  10 . 
     The integrated input device control system  40  may confirm position coordinates of the item which is focused on last through the UI toolkit system  30 . 
     After this, the integrated input device control system  40  may execute an animation of moving from a current position of the cursor, that is, a position of the cursor when a signal corresponding to the input of the control device to enable the display apparatus to leave the pointing mode to a position of the item which is focused on last. 
     For example, referring to  FIG. 7 , it is assumed that the position of the cursor when a signal corresponding to the input of the control device to enable the display apparatus to leave the pointing mode is sensed is s(x1, y1), the item which is focused on last is the item # 2 , and a center position of the item # 2  is s(x2, y2). The integrated input device control system  40  may not directly cause the cursor to disappear from the position s(x1, y1) but execute the animation of moving the cursor from the position s(x1, y1) to the position s(x2, y2) when a signal corresponding to the input of the control device to enable the display apparatus to leave the pointing mode is sensed. The user may not experience that the cursor has abruptly disappeared, and may experience a natural movement of the cursor when entering the focusing mode from the pointing mode by executing the animation. 
     The position at which the cursor is moved need not be the center position of the item which is focused on last, and may be any position on the item which is focused on last. 
     According to an exemplary embodiment, the display apparatus  100  may cause the cursor to disappear from the display  115  after the operation of moving the cursor onto the item which is focused on last is completed. 
     Further, according to another exemplary embodiment, the display apparatus  100  may move the cursor onto the item which is focused on last, and also display by adding a visual effect to the item which is focused on last. 
       FIG. 8  is a reference diagram for describing a display screen when a display apparatus is operated in a focusing mode according to an exemplary embodiment. 
     Referring to  FIG. 8 , the UI toolkit system  30  of the controller  180  may cause the cursor to disappear, and add a visual effect  310  to the item # 2  for indicating that the item # 2  is focused on when the operation of moving the cursor onto the item # 2  which is focused on last is completed as shown in  FIG. 7 . The visual effect  310  which indicates that the item is focused on may be diversely determined, and for example, the visual effect  310  of surrounding a border of the item # 2  with a bold line (see, e.g.,  FIG. 1B ) or differentiating a color of the item # 2  from colors of other items may be applied. 
     The user may move a focus between the items by starting from the item # 2  which is focused using the control device  200   c  having the focusing function. 
     When the display apparatus is operated in the focusing mode in a state in which the item # 2  is focused on, for example, the user may move the focus to the item # 3  adjacent to the right of the item # 2  by pushing a right direction key among the direction key  204  of the control device  200   c  shown in  FIG. 8 . 
     Further, the user may move the focus to the item # 4  adjacent to the right of the item # 3  by pushing the right direction key once more as shown in  FIG. 8 . An example in which the item # 4  is focused on is illustrated in  FIG. 10 . 
       FIG. 9  is a flowchart for describing a display method in a display apparatus according to an exemplary embodiment. 
     Referring to  FIG. 9 , in operation S 910 , the display apparatus  100  senses the input of the control device to enable the display apparatus to leave the focusing mode. 
     The input of the control device to enable the display apparatus to leave the focusing mode may include the activation action of the control device used in the pointing mode. 
       FIG. 10  is a reference diagram for describing input of a control device so that a display apparatus departs a focusing mode according to an exemplary embodiment. 
     Referring to  FIG. 10 , the activation action of the control device used in the pointing mode may include an operation in which the user uses a finger to touch the touch pad  203  of the control device  200   c  in which the pointing function is implemented by including the touch pad. 
     Alternatively, the activation action of the control device used in the pointing mode may include an operation of gripping and moving the control device  200   d  in which the pointing function is implemented without including the touch pad. It should be noted that, in some exemplary embodiments, the activation action including the operation of gripping and moving the control device may also be implemented in the control device  200   c  which includes the touch pad. 
     When a signal corresponding to the input of the control device to enable the display apparatus to leave the focusing mode is sensed, the pointing system  20  of the controller  180  may inform the integrated input device control system  40  of the sensed input in a type of an event. 
     Returning to  FIG. 9 , in operation S 920 , the display apparatus  100  may control the display to cause the cursor displayed in the pointing mode to appear on the item which is focused on last in response to a signal corresponding to the input of the control device to enable the display apparatus to leave the focusing mode. 
       FIG. 11  is a reference diagram for describing a display screen when a display apparatus is operated in a pointing mode according to another exemplary embodiment. 
     Referring to  FIG. 11 , the integrated input device control system  40  which receives an event which indicates that the input of the control device to enable the display apparatus to leave the focusing mode is sensed may cause the cursor  320  displayed in the pointing mode to appear on the item # 4  which is focused on last. 
     The user may control the movement of the cursor from the position of the cursor located on the item # 4  using the control device  200   c  having the pointing function. 
     When entering the pointing mode from the focusing mode, the user may experience a natural and seamless feedback among various input devices by starting to draw the cursor starting to be displayed in the focusing mode on not an arbitrary position on the display  115  but a position in which the focusing operation is complete, that is, the item which is focused on last. 
     The display method according to the above described exemplary embodiments may be recorded in a computer readable recording medium by being implemented in a program instruction form capable of being executed through various computer devices.
