         [0005]    Currently, user interfaces, games, movies, and the like using a three-dimensional (3D) virtual world have been actively developed. With time, the 3D virtual world has been developed from a simple configuration three-dimensionally illustrating an object to various configurations using a method of enhancing a variety of visual effects, interesting elements, real sense, and the like. 
         [0006]    With developments in the 3D virtual world, research is being actively conducted on a method of controlling an object, for example, an avatar in the virtual world. 
         [0007]    However, an existing method of controlling an object of the virtual world is generally performed using a simple operation input method, for example, a method of executing a menu of the object such as select, move and rotate, enlarge and reduce, and the like. 
       SUMMARY 
       [0008]    The foregoing and/or other aspects are achieved by providing an object controlling apparatus, including an input unit to receive, from an input device, a pointing signaling for manipulating an object of a virtual world, a database to store object information associated with the object, and a controller to control at least one of an operation, a state, and a shape of the object based on the pointing signal and the object information.

     DETAILED DESCRIPTION 
       [0030]    Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. Embodiments are described below to explain the present disclosure by referring to the figures. 
         [0031]      FIG. 1  illustrates an operation of an object controlling apparatus  100 , which receives a pointing signal from an input device and manipulates an object of a virtual world according to example embodiments. 
         [0032]    Referring to  FIG. 1 , the object controlling apparatus  100  may receive a pointing signal from an input device, including a first input device  111  or a second input device  112 , or both, to manipulate an object  131  of a virtual world  130 . 
         [0033]    A user  110  of a real world may input, as an input signal, an operation, a state, an intent, a shape, and the like of the user  110  in the input device. The input device may generate the pointing signal for controlling the object  131  of the virtual world  130  based on the input signal. Depending on example embodiments, the input device may generate a plurality of pointing signals. 
         [0034]    The input device may transmit the pointing signal to the object controlling apparatus  100 . 
         [0035]    The input device may act as a device to receive, from the user  110  of the real world, a signal or a command for manipulating the object  131  of the virtual world  130 . 
         [0036]    For example, the input device may be a motion sensor to sense a motion of the user  110  of the real world. When the user moves the motion sensor, the motion sensor may sense a motion of the user  110  and may generate a pointing signal for manipulating the object  131  of the virtual world  130  based on the sensed motion of the user  110 . 
         [0037]    The input device may be a touch screen of a portable terminal. When the user  110  of the real world touches the touch screen of the portable terminal to input a click, a double click, a tap, a double tap, a drag, and the like, the touch screen may sense an input signal of the user  110  and generate a pointing signal for manipulating the object  131  of the virtual world  130  based on the sensed input signal. 
         [0038]    The input device may be a combination of a plurality of devices. 
         [0039]    The input device may correspond to a device that is installed at an end joint of a finger of the user  110  to sense a motion of the finger of the user  110 . When the user  110  generates an input signal using a device sensing the motion of the finger, the device sensing the motion of the finger may sense the input signal of the user  110  and generate a pointing signal for manipulating the object  131  of the virtual world based on the sensed input signal. 
         [0040]    The input device may be a keyboard or a mouse. When the user  110  inputs an input signal using the keyboard or the mouse, the keyboard or the mouse may sense the input signal of the user  110  and generate a pointing signal for manipulating the object  131  of the virtual world  130  based on the sensed input signal. 
         [0041]    The object controlling apparatus  100  may control the object  131  of the virtual world  130 . The object controlling apparatus  100  may receive, from the input device, the pointing signal for controlling the object  131  of the virtual world  130  and may control at least one of an operation, a state, and a shape of the object  131  based on the input pointing signal. 
         [0042]    The object controlling apparatus  100  may control at least one of the operation, the state, and the shape of the object  131  based on object information associated with the object  131  of the virtual world  130  as well as the pointing signal. 
         [0043]    For example, the user  110  may input, in the input device, an operation of lifting up the first input device  111  and putting down the second input device  112 . 
         [0044]    The input device may sense the input operation of the user  110  and generate the pointing signal for manipulating the object  131  of the virtual world  130  based on a signal of the sensed operation. The input device may transmit the pointing signal to the object controlling apparatus  100 . 
         [0045]    The object controlling apparatus  100  may control the shape of the object  131  of the virtual world  130  based on the input pointing signal, for example, a signal about an operation of lifting up a corresponding object and putting down the corresponding object, and object information associated with the object  131  of the virtual world  130 , for example, information regarding a form of a slide phone of which an upper portion slides to be opened. 
         [0046]      FIG. 2  illustrates a configuration of an object controlling apparatus  200  according to example embodiments. 
         [0047]    Referring to  FIG. 2 , the object controlling apparatus  200  may include, for example, an input unit  210 , a controller  220 , and a database  230 . 
         [0048]    The input unit  210  may receive, from an input device, a pointing signal for manipulating an object of a virtual world. The input unit  210  may receive a plurality of pointing signals from the input device. 
         [0049]    The pointing signal may be a coordinate value using 3D pointing coordinates. The object of the virtual world may have a local coordinate system. The pointing signal may be a coordinate value expressed using the local coordinate system of the object.

         [0077]    Referring to  FIG. 3 , the object controlling apparatus  300  may include, for example, an input unit  310 , a controller  320 , a database  330 , a first decision unit  340 , and a second decision unit  350 . 
         [0078]    The input unit  310  may receive a pointing signal from an input device. The input unit  310  may receive a plurality of pointing signals from the input device. 
         [0079]    The database  330  may store internal transform information associated with an internal transform of an object of a virtual world and total transform information associated with a total transform of the object. The internal transform information may include a pointing signal for internally transforming the object. The total transform information may include a pointing signal for totally transforming the object. 
         [0080]    The object of the virtual world may include at least one subpart. The internal transform information may include at least one of identification information used to identify the at least one subpart, translation information associated with a translation of the at least one subpart, rotation information associated with a rotation of the at least one subpart, and scaling information associated with scaling of the at least one subpart. 
         [0081]    The internal transform may indicate a unique transform of the object set for each object. The total transform may indicate a transform set to be commonly applied to all the object(s) in the virtual world. For example, the total transform may indicate an enlargement, a reduction, a rotation, and the like of the object(s). In the case of a slide phone, the internal transform may indicate a transform of the slide phone sliding to be opened, a transform of the slide phone sliding to be closed, a transform whereby a button of the slide phone is pressed, and the like. 
         [0082]    The internal transform information may include a pointing signal for the internal transform of the object. A pointing signal for the internal transform may be set to be different for each object. The total transform information may include a pointing signal for the total transform of the object(s). A pointing signal for the total transform may be set to be different for each object. 
         [0083]    A user may change internal transform information of the object. For example, the user may update the internal transform information by storing the received internal transform information in the database  330 . 
         [0084]    The user may change total transform information of the object(s). For example, the user may set total transform information of the object(s) and input the set total transform information into the object controlling apparatus  300 . The object controlling apparatus  300  may update the total transform information of the object(s) by storing the received total transform information in the database  330 . 
         [0085]    The first decision unit  340  may determine whether an input pointing signal corresponds to a valid input signal. The first decision unit  340  may determine whether the input pointing signal corresponds to the valid input signal, depending on whether the input pointing signal matches one of a pointing signal for internal transform of the object and a pointing signal for total transform of the object that are stored in the database  330 . For example, when the input pointing signal matches one of pointing signals stored in the database  330 , the first decision unit  340  may determine the input pointing signal as the valid input signal. 
         [0086]    When the pointing signal is determined as the valid input signal, the second decision unit  350  may determine whether the pointing signal matches the internal transform information. When the input pointing signal matches the pointing signal for the internal transform of the object that is included in internal transform information stored in the database  330 , the second decision unit  350  may determine the input pointing signal matches the internal transform information. 
         [0087]    When the input pointing signal is determined to match the internal transform information, the controller  320  may control the internal transform of the object based on the internal transform information. When the input pointing signal is determined to not match the internal transform information, the controller  320  may control the total transform of the object(s) based on the total transform information. 
         [0088]    Hereinafter, an operation of an object controlling apparatus to control an object according to example embodiments will be described with reference to  FIG. 4A through 8B . 
         [0089]      FIG. 4A  through  FIG. 4C  illustrate an operation of an object controlling apparatus controlling a slide phone of a virtual world according to example embodiments. 
         [0090]    Referring to  4 A, a slide phone  400  of the virtual world may include, for example, a first subpart  401  and a second subpart  402 . 
         [0091]    The slide phone  400  may further include a third subpart through a fourteenth subpart. The third subpart through the fourteenth subpart may correspond to buttons of a button portion provided on a front portion of the second subpart  402 . The buttons may include number buttons from zero to 9, a “#” button, and a “*” button. 
         [0092]    Total transform information associated with a total transform of the slide phone  400  may include information associated with a transform of the slide phone  400  being enlarged. 
         [0093]    Internal transform information associated with an internal transform of the slide phone  400  may include information regarding a transform whereby a button of the button portion of the second subpart  402  is pressed, and a transform whereby the first subpart  401  and the second subpart  402  translate such that the slide phone  400  slides to be opened and closed. 
         [0094]    Internal transform information associated with an internal transform whereby a button  1  of the button portion is pressed may include information as given by Table 4.

         [0095]    Referring to Table 4, a subpart ID of the button  1  of the button portion may be “3”. 
         [0096]    Also, a translation center indicating a center point that is a translation standard of the button  1  being pressed may correspond to 3D pointing coordinates with respect to the center point of the button  1 . The 3D pointing coordinates indicating the translation center with respect to the button  1  may correspond to a coordinate value expressed using a local coordinate system  403  with respect to the slide phone  400 . 
         [0097]    A translation vector indicating a translation distance and direction of the button  1  being pressed may be (0, 0, −1). For example, the pressed direction of the button  1  may correspond to a translation in a negative direction of a Z axis of the local coordinate system  403 . 
         [0098]    A translation base subpart ID indicating a standard subpart with respect to a transform of a third subpart, for example, the button  1  may be “1”. For example, the button  1  may perform a transform whereby the button is pressed based on the first subpart  401 . 
         [0099]    A translation range indicating a minimum value and a maximum value of the pressed translation of the button  1  may have (0, 5). For example, the button  1  may be pressed in the negative direction of the Z axis of the local coordinates system  403  from a minimum of 0 to a maximum of 5. 
         [0100]    Accordingly, when a pointing signal for a translation corresponding to ‘1’ in the negative direction of the Z axis of the local coordinate system  403  based on a coordinate value corresponding to a center of the button  1  is received from an input device, the object controlling apparatus may control a transform of the slide phone  400  so that the button  1  of the slide phone  400  may be pressed in correspondence to the input pointing signal and object information associated with the slide phone  400 . 
         [0101]    Referring to  FIG. 4B , total transform information associated with a slide phone  410  may include information associated with a transform of the slide phone  410  being enlarged. For example, the total transform information may include information associated with a transform of the slide phone  410  being enlarged to be slide phone  420 . 
         [0102]    When a pointing signal  411  for a translation in a negative direction of an X axis of the local coordinate system  403  and a pointing signal  412  for a translation in a positive direction of the X axis of the local coordinate system  403  are input with respect to the slide phone  410 , the total transform information associated with the slide phone  410  may include information associated with the enlargement transform of the slide phone  410 . 
         [0103]    In this example, when the pointing signals  411  and  412 , with respect to the slide phone  410 , are input from the input device, the object controlling apparatus may enlarge the slide phone  410  based on the input pointing signals  411  and  412 , and the total transform information associated with the slide phone  410 . 
         [0104]    Referring to  FIG. 4C , internal transform information associated with a slide phone  430  may include information associated with a transform of the slide phone  430  sliding to be opened and closed. For example, the internal transform information associated with the slide phone  430  may include information associated with a transform of the slide phone  430  being transformed to be an open slide phone  440 . 
         [0105]    When a pointing signal  431  for a translation in a positive direction of an Y axis of the local coordinate system  403  and a pointing signal  432  for a translation in a negative direction of the Y axis of the local slide phone  403  are input with respect to the slide phone  430 , the internal transform information associated with the slide phone  430  may include information associated with a transform of the slide phone  430  sliding to be opened. 
         [0106]    The object controlling apparatus may control an operation of the slide phone  430  sliding to be opened and closed based on a pointing signal with respect to each of the first subpart  401  and the second subpart  402  of the slide phone  430 . 
         [0107]    Table 5 and Table 6 show internal transform information associated with the transform of the slide phone  430  sliding to be opened and closed. Table 5 shows internal transform information associated with the first subpart  401  in the internal transform information associated with the transform of the slide phone  430  sliding to be opened and closed.

         [0108]    Referring to Table 5, a subpart ID of the first subpart  401  may be “1”. The first subpart  401  may include, as children subparts, a third subpart through a fourteenth subpart. 
         [0109]    A translation center may correspond to 3D pointing coordinates with respect to a center point of the first subpart  401 . 
         [0110]    A translation vector may be (0, −1, 0). For example, in the operation of the slide phone  430  sliding to be opened, a translation direction of the first subpart  401  may correspond to the negative direction of the Y axis of the local coordinate system  403 . 
         [0111]    A translation base subpart ID may be “2”. For example, a standard subpart with respect to a translation transform of the first subpart  401  may correspond to the second subpart  402 . 
         [0112]    A translation range may be (0, 20). For example, in the operation of the slide phone  430  sliding to be opened, the first subpart  401  may be translated in the negative direction of the Y axis of the local coordinate system  403  from a minimum of 0 to a maximum of 20.

         [0114]    Referring to Table 6, a subpart ID of the second subpart  402  may be “2”. 
         [0115]    A translation center may correspond to 3D pointing coordinates with respect to a center point of the second subpart  402 . 
         [0116]    A translation vector may be (0, 1, 0). For example, in the operation of the slide phone  430  sliding to be opened, a translation direction of the second subpart  402  may correspond to the positive direction of the Y axis of the local coordinate system  403 . 
         [0117]    A translation base subpart ID may be “1”. For example, a standard subpart with respect to a translation transform of the second subpart  402  may correspond to the first subpart  401 . 
         [0118]    A translation range may be (0, 20). For example, in the operation of the slide phone  430  sliding to be opened, the second subpart  402  may be translated in the positive direction of the Y axis of the local coordinate system  403  from a minimum of 0 to a maximum of 20. 
         [0119]    When the pointing signal  431  for the translation in the positive direction of the Y axis of the local coordinate system  403  and the pointing signal  432  for the translation in the negative direction of the Y axis of the local slide phone  403  with respect to the slide phone  430  are input from the input device, the object controlling apparatus may slide the slide phone  430  to be opened based on the input pointing signals  431  and  432 , and internal transform information associated with the slide phone  430 . 
         [0120]      FIG. 5A  through  FIG. 5C  illustrate an operation of an object controlling apparatus controlling a bottle of a virtual world according to example embodiments. 
         [0121]    Referring to  FIG. 5A , a bottle  500  of a virtual world may include a first subpart  501  corresponding to a bottle cap and a second subpart  502  corresponding to a body of the bottle  500 . 
         [0122]    Internal transform information associated with an internal transform of the bottle  500  may include information associated with a transform of the first subpart  501  and the second subpart  502  being separated from each other. 
         [0123]    Total transform information associated with a total transform of the bottle  500  may include information associated with a transform of the bottle  500  being enlarged or reduced. 
         [0124]    Referring to  FIG. 5B , total transform information associated with a bottle  510  may include information associated with an enlargement and reduction transform of the bottle  510 . For example, the total transform information associated with the bottle  510  may include information associated with a transform of the bottle  510  being enlarged to be a bottle  520  or a transform of the bottle  510  being reduced to be a bottle  530 . 
         [0125]    When a pointing signal  511  corresponding to a black arrow indicator for a translation in a negative direction of an X axis of a local coordinate system  503  and a pointing signal  512  corresponding to a black arrow indicator for a translation in a positive direction of the X axis of the local coordinate system  503  are input with respect to the bottle  510 , total transform information associated with the bottle  510  may include information associated with the enlargement transform of the bottle  510 . 
         [0126]    In this example, when the pointing signals  511  and  512 , corresponding to the black arrow indicators with respect to the bottle  500 , are input from an input device, the object controlling apparatus may enlarge the bottle  510  based on the input pointing signals  511  and  512  and total transform information associated with the bottle  510 . 
         [0127]    When the pointing signal  511  corresponding to a shaded arrow indicator for the translation in the positive direction of the X axis of the local coordinate system  503  and the pointing signal  512  corresponding to a shaded arrow indicator for a translation in the negative direction of the X axis of the local coordinate system  503  are input with respect to the bottle  510 , the total transform information associated with the bottle  510  may include information associated with the reduction transform of the bottle  510 . 
         [0128]    In this example, when the pointing signals  511  and  512 , corresponding to the shaded arrow indicators with respect to the bottle  510 , are input from the input device, the object controlling apparatus may reduce the bottle  510  based on the input pointing signals  511  and  512 , and total transform information associated with the bottle  510 . 
         [0129]    Referring to  FIG. 5C , internal transform information associated with a bottle  540  may include information associated with a transform whereby a bottle cap of the bottle  540  is separated from the bottle  540 . For example, the internal transform information associated with the bottle  540  may include information associated with a transform whereby the bottle cap of the bottle  540  is separated and thus the bottle  540  is transformed to be a bottle  550 . 
         [0130]    When a pointing signal  541  for a translation in a positive direction of an Y axis of the local coordinate system  503  and a pointing signal  542  for a translation in a negative direction of the Y axis of the local coordinate system  503  are input with respect to the bottle  540 , the internal transform information associated with the bottle  540  may include information associated with the transform whereby the bottle cap of the bottle  540  is separated. 
         [0131]    The object controlling apparatus may control an operation of separating the bottle cap of the bottle  510  based on a pointing signal with respect to each of the first subpart  501  and the second subpart  502  of the bottle  540 . 
         [0132]    Table 7 and Table 8 shown internal transform information associated with the transform whereby the bottle cap of the bottle  540  is separated. Table 7 shows internal transform information associated with the first subpart  501  in the internal transform information associated with the transform whereby the bottle cap of the bottle  540  is separated.

         [0133]    Referring to Table 7, a subpart ID of the first subpart  501  may be “1”. 
         [0134]    A translation center may correspond to 3D pointing coordinates with respect to a center point of the first subpart  501 . 
         [0135]    A translation vector may be (0, 1, 0). For example, in the operation of separating the bottle cap of the bottle  540 , a translation direction of the first subpart  501  may correspond to the positive direction of the Y axis of the local coordinate system  503 . 
         [0136]    A translation base subpart ID may be “2”. For example, a standard subpart with respect to a translation transform of the first subpart  501  may correspond to the second subpart  502 . 
         [0137]    A translation range may be (−5, ∞). For example, in the operation of separating the bottle cap of the bottle  540 , the first subpart  501  may be translated in the positive direction of the Y axis of the local coordinate system  503  from a minimum of −5 to a maximum of ∞. 
         [0138]    Table 8 shows internal transform information associated with the second subpart  502  in the internal transform information associated with the transform of separating the bottle cap of the bottle  540 .

         [0139]    Referring to Table 8, a subpart ID of the second subpart  502  may be “2”. 
         [0140]    A translation center may correspond to 3D pointing coordinates with respect to a center point of the second subpart  502 . 
         [0141]    A translation vector may be (0, −1, 0). For example, in the operation of separating the bottle cap of the bottle  540 , a translation direction of the second subpart  502  may correspond to the negative direction of the Y axis of the local coordinate system  503 . 
         [0142]    A translation base subpart ID may be “1”. For example, a standard subpart with respect to a translation transform of the second subpart  502  may correspond to the first subpart  501 . 
         [0143]    A translation range may be (0, 20). For example, in the operation of separating the bottle cap of the bottle  540 , the second subpart  502  may be translated in the negative direction of the Y axis of the local coordinate system  503  from a minimum of 0 to a maximum of 20. 
         [0144]    When the pointing signal  541  for the translation in the positive direction of the Y axis of the local coordinate system  503  and the pointing signal  542  for the translation in the negative direction of the Y axis of the local coordinate system  503  with respect to the bottle  540  are input from the input device, the object controlling apparatus may separate the bottle cap from the bottle  540 . 
         [0145]      FIG. 6A  through  FIG. 6C  illustrate an operation of an object controlling apparatus controlling a door of a virtual world according to example embodiments. 
         [0146]    Referring to  FIG. 6A , a door  600  of a virtual world may include a first subpart  601  and a second subpart  602 . 
         [0147]    Internal transform information associated with an internal transform of the door  600  may include information associated with a transform of the second subpart  602  rotating, for example, pivoting to be opened based on an axis b  605  provided between the first subpart  601  and the second subpart  602 . 
         [0148]    Total transform information associated with a total transform of the door  600  may include information associated with a transform of the door  600  rotating based on an axis a  604 . 
         [0149]    Referring to  FIG. 6B , total transform information associated with a door  610  may include information associated with a transform of the door  610  rotating based on the axis a  604 . For example, the total transform information associated with the door  610  may include information associated with a transform of the door  610  rotating to be a door  620 . 
         [0150]    When a pointing signal  611  for holding a predetermined portion of the second subpart  602  and a pointing signal  612  for a translation in a positive direction of an X axis of a local coordinate system  603  with respect to the door  610  are input with respect to the door  610 , the total transform information associated with the door  610  may include information associated with the transform of the door  610  rotating based on the axis a  604 . 
         [0151]    In this example, when the pointing signals  611  and  612 , with respect to the door  610 , are input from an input device, the object controlling apparatus may rotate the door  610  based on the axis a  604 , using the input pointing signals  611  and  612  and the total transform information associated with the door  610 . 
         [0152]    Referring to  FIG. 6C , internal transform information associated with a door  630  may include information associated with a transform of the door  630  rotating based on the axis  605  to be opened. For example, the internal transform information associated with the door  630  may include information associated with the transform of the door  630  rotating to be an opened door  640 . 
         [0153]    When a pointing signal  631  for holding a predetermined portion of the first subpart  601  and a pointing signal  632  for a translation in the positive direction of the X axis of the local coordinate system  603  are input with respect to the door  630 , the internal transform information associated with the door  630  may include information associated with the transform of the door  630  rotating to be opened.

         [0155]    Referring to Table 9, a subpart ID of the second subpart  602  may be “2”. The second subpart  602  may include the first subpart  601  as a children subpart. 
         [0156]    A rotation center may be (b, 0, 0). For example, the second subpart  602  may rotate based on an axis where a value of the X axis of the local coordinate system  603  is b and a value of each of an Y axis and a Z axis is 0, that is, based on the axis b  605  where x=b. 
         [0157]    A rotation vector may be (0, 0, 1). For example, in the operation of the door  630  rotating to be opened, a translation direction of the second subpart  602  may correspond to a positive direction of the Z axis of the local coordinate system  603 . 
         [0158]    A rotation base subpart ID may be “1”. For example, a standard subpart with respect to a rotation transform of the second subpart  602  may correspond to the first subpart  601 . 
         [0159]    A rotation range may be (0, 90). For example, in the operation of the door  630  rotating to be opened, the second subpart  602  may be translated in the positive direction of the Z axis from minimum zero degree to a maximum of 90 degrees. 
         [0160]    When the pointing signal  631  for holding the predetermined portion of the first subpart  601  and the pointing signal  632  for the translation in the positive direction of the X axis of the local coordinate system  603  with respect to the door  630  are input from an input device, the object controlling apparatus may rotate the door  630  based on the axis b  605 . 
         [0161]      FIG. 7A  through  FIG. 7E  illustrate an operation of an object controlling apparatus controlling a spring of a virtual world according to example embodiments. 
         [0162]    Referring to  FIG. 7A , a spring  700  of a virtual world may include a first subpart  701 . For example, the spring  700  may include only a single subpart  701 . 
         [0163]    Internal transform information associated with an internal transform of the spring  700  may include information associated with a transform of the first subpart  701  being compressed or expanded. 
         [0164]    Total transform information associated with a total transform of the spring  700  may include information associated with a transform of the first subpart  701  being scaled up or down, that is, enlarged or reduced. 
         [0165]    Referring to  FIG. 7B , total transform information associated with a spring  710  may include information associated with a transform of the spring  710  being scaled down, that is, reduced. For example, total transform information associated with the spring  710  may include information associated with the transform of the spring  710  reduced to be a spring  720 . 
         [0166]    When a pointing signal  711  having a predetermined value of a Z axis of a local coordinate system  702  with respect to the spring  710  and for a translation in a negative direction of a Y axis, and a pointing signal  712  having the same value of the Z axis as the value of the Z axis of the pointing signal  711  and for a translation in a positive direction of the Y axis are input, total transform information associated with the transform  710  may include information associated with a reduction transform of the spring  710 . 
         [0167]    In this example, when the pointing signals  711  and  712  with respect to the spring  710  are input from an input device, the object controlling apparatus may reduce the spring  710  based on the input pointing signals  711  and  712 , and total transform information associated with the spring  710 . 
         [0168]    Referring to  FIG. 7C , total transform information associated with a spring  730  may include information associated with a transform of the spring  730  being enlarged, that is, scaled up. For example, the total transform information associated with the spring  730  may include information associated with a transform of the spring  730  being enlarged to be a spring  740 . 
         [0169]    When a pointing signal  731  having a predetermined value of the Z axis of the local coordinate system  702  with respect to the spring  730  and for a translation in a negative direction of an X axis, and a pointing signal  732  having a value of the Z axis different from the value of the Z axis of the pointing signal  731  in the local coordinate value  702  and for a translation in a positive direction of the X axis are input with respect to the spring  730 , total transform information associated with the spring  730  may include information associated with an enlargement transform of the spring  730 . 
         [0170]    In this example, when the input signals  731  and  732  with respect to the spring  730  are input from an input device, the object controlling apparatus may enlarge the spring  730  based on the input pointing signals  731  and  732 , and total transform information associated with the spring  730 . 
         [0171]    Referring to  FIG. 7D , internal transform information associated with a spring  750  may include information associated with a transform of the spring  750  being compressed. For example, the internal transform information associated with the spring  750  may include information associated with a transform of the spring being compressed to be a spring  760 . 
         [0172]    When a pointing signal  751  having a predetermined value of a Z axis of the local coordinate system  702  with respect to the spring  750  and for a translation in the negative direction of the Y axis, and a pointing signal  752  having a value of the Z axis different from the value of the Z axis of the pointing signal  751  and for a translation in the positive direction of the Y axis of the local coordinate system  702  are input, internal transform information associated with the spring  750  may include information associated with a transform of the spring  750  being compressed. 
         [0173]    The object controlling apparatus may control an operation of the spring  750  being compressed based on a pointing signal with respect to the first subpart  701  of the spring  750 . 
         [0174]    Table 10 shows internal transform information associated with the transform of the spring  750  being compressed.

         [0175]    Referring to Table 10, a subpart ID of the first subpart  701  may be “1”. 
         [0176]    A scaling center may be (0, 0, 0). For example, the first subpart  701  may be compressed based on an origin of the local coordinate system  702 . 
         [0177]    A scaling vector may be (0, 1, 0). For example, in the operation of compressing the spring  750 , a translation direction of the first subpart  701  may correspond to the positive direction of the Y axis of the local coordinate system  702 . 
         [0178]    A scaling base subpart ID may be none. For example, since the spring  750  includes only a single subpart, no standard subpart is provided for the transform of the first subpart  701  being compressed. 
         [0179]    A scaling range may be (−40, 40). For example, in the operation of compressing the spring  750 , the first subpart  701  may be compressed in the positive direction of the Y axis of the local coordinate system  702  from a minimum of −40 to a maximum of 40. 
         [0180]    When a pointing signal  751  having a predetermined value of the Z axis of the local coordinate system  702  with respect to the spring  750  and for a translation in the negative direction of the Y axis, and a pointing signal  752  having a value of the Z axis different from the value of the Z axis of the pointing signal  751  and for a translation in the positive direction of the Y axis of the local coordinate system  702  are input from an input device, the object controlling apparatus may compress the spring  750  based on the input pointing signals  751  and  752 , and internal transform information associated with the spring  750 . 
         [0181]    Referring to  FIG. 7E , internal transform information associated with a spring  770  may include information associated with a transform of the spring  770  being expanded. For example, the internal transform information associated with the spring  770  may include information associated with the transform of the spring  770  being expanded to be a spring  780 . 
         [0182]    When a pointing signal  771  having a predetermined value of the Z axis of the local coordinate system  702  with respect to the spring  770  and for a translation in the positive direction of the Y axis, and a pointing signal  772  having the same value of the Z axis as the value of the Z axis of the pointing signal  771  and for a translation in the negative direction of the Y axis of the local coordinate system  702  are input, internal transform information associated with the spring  770  may include information associated with the transform of the spring  770  being expanded. 
         [0183]    In this example, when the pointing signals  771  and  772  with respect to the spring  770  are input from an input device, the object controlling apparatus may expand the spring  770  based on the input pointing signals  771  and  772 , and internal transform information associated with the spring  770 . 
         [0184]      FIG. 8A  and  FIG. 8B  illustrate an operation of an object controlling apparatus controlling a folder phone of a virtual world according to example embodiments. 
         [0185]    Referring to  FIG. 8A , a folder phone  800  of a virtual world may include a first subpart  801  corresponding to a top folder of the folder phone  800  and a second subpart  802  corresponding to a bottom folder of the folder phone  800 . 
         [0186]    Internal transform information associated with an internal transform of the folder phone  800  may include information associated with a transform of the folder phone  800  being opened.

         [0188]    Referring to Table 11, a subpart ID of the first subpart  801  may be “1”. 
         [0189]    A rotation center may be (0, 0, 0). For example, the first subpart  801  may rotate based on an origin of a local coordinate system  803 . 
         [0190]    A rotation vector may be (1, 0, 0). For example, in the operation of opening the folder phone  800 , a translation direction of the first subpart  801  may correspond to a positive direction of an X axis of the local coordinate system  803 . 
         [0191]    A rotation base subpart ID may be “2”. For example, a standard subpart with respect to a rotation transform of the first subpart  801  may correspond to the second subpart  802 . 
         [0192]    A rotation range may be (0, 70). For example, in the operation of opening the folder phone  800 , the first subpart  801  may be translated from minimum zero degree to maximum 70 degrees. 
         [0193]    A subpart ID of the second subpart  802  may be “2”. 
         [0194]    A rotation center may be (0, 0, 0). For example, the second subpart  802  may rotate based on an origin of the local coordinate system  803 . 
         [0195]    A rotation vector may be (1, 0, 0). For example, in the operation of opening the folder phone  800 , a translation direction of the second subpart  802  may correspond to the positive direction of the X axis of the local coordinate system  803 . 
         [0196]    A rotation base subpart ID may be “1”. For example, a standard subpart with respect to a rotation transform of the second subpart  802  may correspond to the first subpart  801 . 
         [0197]    A rotation range may be (0, 70). For example, in the operation of opening the folder phone  800 , the second subpart  802  may be translated from minimum zero degree to maximum 70 degrees. 
         [0198]    Referring to  FIG. 8B , internal transform information associated with a folder phone  810  may include information associated with a transform of the folder phone  810  being opened. For example, the internal transform information associated with the folder phone  810  may include information associated with the transform of the folder phone  810  being transformed to be an opened folder  820 . 
         [0199]    A plurality of pointing signals  811 ,  812 ,  813 ,  814 ,  815 , and  816  may be input with respect to the folder phone  810 . 
         [0200]    The object controlling apparatus may determine whether a valid input signal is present among a plurality of pointing signals input from an input device. 
         [0201]    For example, a combination of the pointing signals  811  and  812  among the plurality of pointing signals  811 ,  812 ,  813 ,  814 ,  815 , and  816  may correspond to the valid input signal. In this example, the object controlling apparatus may determine, as the valid input signal with respect to the folder phone  810 , the combination of the pointing signal  811  having a predetermined value of an Y axis of a local coordinate system  803  with respect to the folder phone  810  and for a translation in a negative direction of a Z axis, and the pointing signal  812  having a value of the Y axis different from the value of the Y axis of the pointing signal  811  and for a translation in the negative direction of the Z axis. The object controlling apparatus may control the folder phone  810  to be opened based on the pointing signals  811  and  812  that are determined as valid input signals, and the internal transform information associated with the folder phone  810 . 
         [0202]      FIG. 9  illustrates an object controlling method according to example embodiments. 
         [0203]    Referring to  FIG. 9 , in operation  910 , a pointing signal for manipulating an object of a virtual world may be received from an input device. Depending on example embodiments, a plurality of pointing signals may be received. 
         [0204]    The pointing signal may correspond to a coordinate value using 3D pointing coordinates. The object of a virtual world may have a local coordinate system. The pointing signal may be a coordinate value expressed using a local coordinate system of the object. 
         [0205]    The object may include at least one subpart. Object information may include at least one of identification information used to identify the at least one subpart, and transform information associated with a transform of the at least one subpart. 
         [0206]    The transform information may include at least one of translation information associated with a translation of the at least one subpart, rotation information associated with a rotation of the at least one subpart, and scaling information associated with scaling of the at least one subpart. 
         [0207]    In operation  920 , at least one of an operation, a state, and a shape of the object may be controlled based on the pointing signal and object information associated with the object that is stored in a database. 
         [0208]      FIG. 10  illustrates an object controlling method according to other example embodiments. 
         [0209]    Referring to  FIG. 10 , in operation  1010 , a pointing signal may be received from an input device. Depending on example embodiments, a plurality of pointing signals may be received. 
         [0210]    In operation  1020 , whether the input pointing signal corresponds to a valid input signal may be determined. 
         [0211]    Depending on example embodiments, whether the input pointing signal corresponds to a valid input signal may be determined depending on whether the input pointing signal matches one of a pointing signal for an internal transform of the object and a pointing signal for a total transform of the object that are stored in a database. For example, when the input pointing signal matches one of the pointing signals stored in the database, the object controlling method may determine the input pointing signal as a valid input signal. 
         [0212]    The database may include internal transform information associated with the internal transform of the object of the virtual world and total transform information associated with the total transform of the object. The internal transform information may include the pointing signal for the internal transform of the object. The total transform information may include the pointing signal for the total transform of the object. 
         [0213]    The object of the virtual world may include at least one subpart. The internal transform information may include at least one of identification information used to identify the at least one subpart, translation information associated with a translation of the at least one subpart, rotation information associated with a rotation of the at least one subpart, and scaling information associated with scaling of the at least one subpart. 
         [0214]    The internal transform may indicate a unique transform of the object set for each object. The total transform indicates a transform set to be commonly applied to all the object(s) in the virtual world. For example, the total transform may indicate an enlargement, a reduction, a rotation, and the like of the object(s). In the case of a slide phone, the internal transform may indicate a transform of the slide phone sliding to be opened, a transform of the slide phone sliding to be closed, a transform whereby a button of the slide phone is pressed, and the like. 
         [0215]    The internal transform information may include a pointing signal for the internal transform of the object. A pointing signal for the internal transform of the object may be set to be different for each object. The total transform information may include a pointing signal for the total transform of the object. A pointing signal for the total transform of the object may be set to be different for each object. 
         [0216]    A user may change internal transform information of the object. For example, the user may update the internal transform information by storing the received internal transform information in the database. 
         [0217]    The user may change total transform information of the object. For example, the user may set total transform information of the object(s). The object controlling method may update the total transform information of the object(s) by storing the received total transform information in the database. 
         [0218]    When the input pointing signal is determined to not be the valid input signal, the object controlling method may return to operation  1010  of receiving the pointing signal from the input device without controlling the operation of the object and the like. 
         [0219]    Conversely, when the input pointing signal is determined to be the valid input signal, whether the input pointing signal matches the internal transform information may be determined in operation  1030 . 
         [0220]    When the input pointing signal matches the pointing signal for the internal transform of the object that is included in the internal transform information stored in the database, the input pointing signal may be determined to match the internal transform information. 
         [0221]    When the input pointing signal is determined to match the internal transform information, the internal transform of the object may be controlled based on the internal transform information in operation  1040 . 
         [0222]    Conversely, when the input pointing signal is determined to not match the internal transform information, the total transform of the object may be controlled based on the total transform information in operation  1050 . 
         [0223]    The object controlling method according to the above-described embodiments may be recorded in non-transitory computer-readable media including program instructions to implement various operations embodied by a computer. The media may also include, alone or in combination with the program instructions, data files, data structures, and the like. Examples of non-transitory computer-readable media include magnetic media such as hard disks, floppy disks, and magnetic tape; optical media such as CD ROM disks and DVDs; magneto-optical media such as optical disks; and hardware devices that are specially configured to store and perform program instructions, such as read-only memory (ROM), random access memory (RAM), flash memory, and the like. 
         [0224]    Examples of program instructions include both machine code, such as produced by a compiler, and files containing higher level code that may be executed by the computer using an interpreter. The described hardware devices may be configured to act as one or more software modules in order to perform the operations of the above-described embodiments, or vice versa. Any one or more of the software modules or units described herein may be executed by a dedicated processor unique to that unit or by a processor common to one or more of the modules. The described methods may be executed on a general purpose computer or processor or may be executed on a particular machine such as described herein.
