Description

  The present invention relates to an information processing apparatus and method, and a program, and more particularly, to an information processing apparatus and method for operating a target by drag and drop, and a program.

  Conventionally, a GUI (Graphical User Interface) has been adopted in a device such as a personal computer that can be directly operated by a user. The GUI is generally said to be easy to use for beginners because it can be operated intuitively compared to a command-based interface. In such a GUI, there are many devices that can be dragged and dropped.

  Drag and drop specifies the icon of a predetermined target (movement source) as the start point and the icon of another target (movement destination) as the end point, and uses a pointing device such as a mouse to point the pointer at the movement source icon. The operation is to press the mouse button repeatedly, move the pointer to the destination icon while pressing the mouse button, and release the mouse button when the pointer reaches the destination icon.

  By drag-and-drop, it is possible to apply processing corresponding to drag-and-drop to the movement source target and the movement destination target.

  Since drag-and-drop is an operation similar to directly operating a target, drag-and-drop has an advantage that the user can easily understand the contents intuitively. Drag-and-drop is also easy and easy to use once the user understands it.

  However, it is difficult for a user who uses the device for the first time to know which can be dragged and dropped, which can be moved to, and what happens when dragged and dropped. .

  In order to cope with this, there are some which display as text help what can be dropped and what happens when dropped at a place where it can be dropped (see, for example, Patent Document 1).

JP 2001-306207 A

  However, even if the drag-and-drop character help is displayed, it is not possible to know whether or not the drag-and-drop operation can be performed at this point. For example, there is a case where a target to be dragged and dropped is currently used by another user and cannot be dragged and dropped, and the user knows whether or not the desired target can be dragged and dropped. Can not.

  Under such circumstances, it is necessary for the user to infer which object can be dragged and dropped, or what kind of processing is executed by the drag and drop, which is not convenient. In addition, when such a guess is lost, a process different from the intended process is executed.

  In addition, due to restrictions on the display screen, if there are a large number of drag and drop operations, text help cannot be displayed on the screen at once, and complicated operations are required to read the help. .

  The present invention has been made in view of such a situation, and enables a user to be notified whether or not a drag-and-drop operation can be performed easily and quickly.

  The information processing method or program according to one aspect of the present invention determines whether an icon is indicated by a pointer satisfying a predetermined condition (for example, step S12 in FIG. 3), and the icon satisfies the condition and the icon is When it is determined that the pointer is instructed, the movement source represented by the icon designated by the pointer and the object on the screen of the drag and drop destination to which the icon of the movement source is dragged and dropped are displayed. 3 is specified (for example, steps S13 to S19 in FIG. 3), and the display of an animation for dragging and dropping the source icon to the destination object is controlled (for example, FIG. 3). Steps S20 and S21) are included.

  FIG. 1 is a block diagram showing an example of the configuration of a personal computer according to an embodiment of the present invention. A CPU (Central Processing Unit) 11 executes various processes according to a program stored in a ROM (Read Only Memory) 12 or a storage unit 18. A RAM (Random Access Memory) 13 appropriately stores programs executed by the CPU 11 and data. The CPU 11, ROM 12, and RAM 13 are connected to each other by a bus 14.

  As the CPU 11, a cell described in "Birth of Cell", Nikkei Electronics, Nikkei BP, February 28, 2005, pages 89 to 117 can be used.

  An input / output interface 15 is also connected to the CPU 11 via the bus 14. The input / output interface 15 is connected to an input unit 16 including a keyboard, a mouse, and a microphone, and an output unit 17 including a display and a speaker. The CPU 11 executes various processes in response to commands input from the input unit 16. Then, the CPU 11 outputs the processing result to the output unit 17.

Get etc. The acquired program and data are transferred to and stored in the storage unit 18 as necessary.

  FIG. 2 is a block diagram showing a configuration of a program executed on the personal computer. In the personal computer, an application program 41 and an OS (Operating System) 42 are executed.

  The application program 41 includes a determination unit 51, a movement source movement destination specifying unit 52, a display control unit 53, and items 54-1 to 54-8.

  The application program 41 applies various processes to the items 54-1 to 54-8. The application program 41 displays an animation indicating a drag-and-drop operation when a predetermined icon on the screen is designated by a pointer.

  The OS 42 is an operating system such as Windows (registered trademark) or Mac OS (registered trademark) X, and controls basic operations of the personal computer. That is, the OS 42 is basic control software. The OS 42 supplies the application program 41 with position information indicating the position of the pointer on the screen and operation information indicating an operation on the input unit 16 such as a mouse. For example, when the button of the input unit 16 that is a mouse is pressed, the OS 42 indicates that the button is pressed, and supplies information indicating the position of the pointer on the screen when the button is pressed to the application program 41. To do. For example, when the icon is pointed with the pointer, the OS 42 supplies an ID for specifying the pointed icon to the application program 41.

  The determination unit 51 determines whether or not an icon is designated with a pointer satisfying a predetermined condition. For example, the determination unit 51 determines whether or not an icon is designated with a pointer based on position information and operation information from the OS 42 and satisfying a predetermined condition.

  When it is determined that the icon is indicated by the pointer satisfying the condition, the movement source movement destination specifying unit 52 drags and drops the movement source represented by the icon indicated by the pointer and the icon of the movement source. The movement destination represented by the object on the drag-and-drop destination screen is specified.

  The display control unit 53 controls display of an animation of dragging and dropping a source icon to a destination object.

  Items 54-1 to 54-8 are objects that contain data or data and methods. Items 54-1 to 54-8 correspond to objects on the screen, respectively. The object here is, for example, an icon or an area.

  Hereinafter, when it is not necessary to distinguish the items 54-1 to 54-8 individually, they are simply referred to as items 54.

  The number of items 54 is not limited to eight and can be any number.

  Next, a drag and drop animation display process will be described with reference to the flowchart of FIG. In step S <b> 11, the determination unit 51 acquires information indicating the state of the pointer instruction. For example, in step S <b> 11, the determination unit 51 operates as an example of position information indicating the position of the pointer on the screen of the output unit 17, which is a display, and an operation to the input unit 16 such as a mouse, as an example of information indicating a pointer instruction state. Is obtained from the OS 42. In step S12, the determination unit 51 determines whether or not the item icon has been instructed for 3 seconds or more from the information indicating the instruction state of the pointer. If it is determined that the item icon has been instructed for 3 seconds or more, the process proceeds to step S13.

  In step S12, the determination unit 51 may determine whether or not an icon is instructed with a pointer continuously for a predetermined period of time, not limited to 3 seconds. Alternatively, for example, in step S12, the determination unit 51 indicates that the pointer indicates an icon while a predetermined key of the keyboard constituting the input unit 16, for example, the Shift key, the Ctrl key, the Alt key, the space key, or the like is pressed. It may be determined whether or not it has been done.

  FIG. 4 is a diagram illustrating an example of an image that the application program 41 displays on the output unit 17 that is a display. The window 81 is an image for inputting an instruction to the application program 41 and outputting the processing result of the application program 41. For example, the window 81 includes three regions 82 to 84.

  For example, the area 82 is an area for displaying an icon of the item 54 that is a source of definition of each state of the state machine to be generated by the application program 41. The area 83 is an area for generating a specific description of any state of the state machine. The area 84 is an area for displaying an icon of the item 54 corresponding to each state of the state machine to be generated.

  For example, in the region 82, icons 85-1 to 85-4 corresponding to the items 54-1 to 54-4 to be moved (movement source) in the drag-and-drop operation are displayed. . For example, the items 54-1 to 54-4 constitute a library that is a set of objects that are the source of definition of each state of the state machine.

  For example, in the region 84, any of the items 54-1 to 54-4 as the movement source is dragged and dropped, and the items 54-5 to 54-10 (item 54-) to be other targets (movement destinations) are dragged and dropped. 9 and 54-10 are not shown), and icons 86-1 to 86-6 corresponding to each of them are displayed. Items 54-5 through 54-10 each describe one state of the state machine.

  When the resource such as the item 54 is not occupied, in the window 81, the user drags and drops one of the icons 85-1 to 85-4 in the area 82 to the area 83, or It can be dragged and dropped to any of the icons 86-1 to 86-6.

  That is, for example, the user operates the mouse of the input unit 16 to move the pointer 87 on the display screen of the output unit 17, and the mouse button with the pointer 87 over the icon 85-1 in the region 82. And the pointer 87 is moved to the icon 86-1 in the region 84 while the mouse button is pressed. When the pointer 87 reaches the icon 86-1, the user releases the mouse button of the input unit 16. In this manner, the icon 85-1 in the area 82, which is an example of the movement source, is dragged and dropped onto the icon 86-1 in the area 84, which is an example of the movement destination.

  In step S11, for example, the determination unit 51 determines whether or not the pointer 87 illustrated in FIG. 4 indicates the icon 85-3 for 3 seconds or more. The determination unit 51 supplies the determination result to the movement source movement destination specifying unit 52. In this case, the determination unit 51 supplies an ID for specifying the icon designated by the pointer to the movement source movement destination identification unit 52.

  In step S <b> 13, the movement source movement destination specifying unit 52 inquires of the point item that is the item 54 for which the icon is instructed about the movement destination item that is the movement destination item 54 to be dragged and dropped. That is, in step S <b> 13, the movement source movement destination identification unit 52 identifies the item 54 corresponding to the instructed icon based on the ID supplied from the determination unit 51. Then, the movement source movement destination identification unit 52 inquires of the point item that is the identified pointed item 54 about the movement destination item.

  In step S14, the movement source movement destination specifying unit 52 acquires an item ID for specifying the movement destination item from the point item.

  For example, in step S <b> 13, the movement source movement destination identification unit 52 calls the item 54 that is a point item by designating a callback function registered in advance for each item 54. Then, since the item 54 calls the callback function and notifies the movement source movement destination identification unit 52 of the item ID for identifying the item 54 that is the movement destination item, the movement source movement destination identification unit 52 Get an ID.

  For example, the item ID for specifying the destination item is registered in the item 54 in advance.

  In step S15, the movement source movement destination specifying unit 52 inquires whether it is possible to move to the movement destination item based on the selected item ID.

  In step S <b> 16, the movement source movement destination specifying unit 52 acquires a response indicating whether movement is possible from the movement destination item.

  For example, in step S15, the movement source movement destination specifying unit 52 specifies a callback function registered in advance for each item 54, and calls the item 54 that is the movement destination item specified by the selected item ID. Then, since the item 54 that is the movement destination item calls the callback function and transmits a response indicating whether or not the movement is possible, the movement source movement destination specifying unit 52 acquires the response in step S16. To do.

  For example, when the destination item specified by the selected item ID has been edited by another user at that time, the item 54 that is the destination item transmits a response indicating that the item cannot be moved. Therefore, in step S <b> 16, the movement source movement destination specifying unit 52 acquires a response indicating that the item 54 is not movable (cannot be moved).

  For example, if the destination item identified by the selected item ID is not occupied by another user at that time, the item 54 that is the destination item transmits a response indicating that it can be moved. Therefore, in step S16, the movement source movement destination specifying unit 52 obtains a response indicating that the item 54 can be moved (moveable).

  For example, when the destination item specified by the selected item ID is occupied to execute a predetermined process at that time, or when changing the state is prohibited, the item 54 is the source A response indicating that movement is not possible is transmitted to the movement destination specifying unit 52.

  If the user is not authorized to access the destination item specified by the selected item ID, the item 54 that is the destination item may transmit a response indicating that the item cannot be moved. .

  In step S17, the movement source movement destination specifying unit 52 determines whether or not all the movement destination items have been inquired. If it is determined that all the movement destination items have not been inquired, the process returns to step S15, and the next Item ID is selected, and the above-described processing is repeated for the next destination item.

  If it is determined in step S17 that all destination items have been inquired, the procedure proceeds to step S18.

  In step S18, the movement source movement destination specifying unit 52 generates a combination of the point item and the movement destination item. In step S19, the movement source movement destination specifying unit 52 thins the combination.

  For example, in step S19, when the movement destination is a plurality of items 54 of the same type, the movement source movement destination specifying unit 52 leaves one of the combinations of the same type of movement destination items, Thinning out the combinations to erase the combinations.

  Here, the same type of item 54 refers to an item 54 having the same predetermined attribute. For example, since the items 54-5 to 54-10 in which the icons 86-1 to 86-6 are displayed in the area 84 correspond to one state of the state machine, the attributes are the same. , The same type of item 54.

  For example, in step S <b> 19, the movement source movement destination specifying unit 52 thins out the combinations so that only the combination of the movement destination item with the smallest item ID and the point item is left among the combinations of movement destination items of the same type. .

  Further, for example, the movement source movement destination specifying unit 52 moves the icon closest to the point item icon on the screen among combinations of movement item items of the same type based on the position of the icon on the screen. The combination is thinned out so that only the combination of the previous item and the point item remains. Furthermore, for example, the movement source movement destination specifying unit 52 thins out the combinations so that the combination of the movement item and the point item whose icons are displayed on the screen remains among the combinations of the movement item of the same type. .

  For example, priorities may be assigned to the items 54 in advance, and the movement source destination specifying unit 52 may thin out combinations based on the priorities.

  The specific procedure for thinning out the combination may be any procedure.

  The movement source movement destination specifying unit 52 supplies the display control unit 53 with an item ID for specifying the point item and the movement destination item in the combination left after thinning.

  In step S20, the display control unit 53 generates animation display data for displaying a drag-and-drop animation corresponding to the combination. For example, in step S20, the display control unit 53 identifies the icon corresponding to the point item from the item ID acquired from the movement source movement destination identification unit 52, and the ID that identifies the icon corresponding to the movement destination item. The display control unit 53 makes an inquiry to the OS 42 based on the ID for specifying the icon corresponding to the point item and the ID for specifying the icon corresponding to the destination item, and the OS 42 supports the point item. The image data of the icon corresponding to the position on the screen of the icon to be moved and the point item, and the image position of the icon corresponding to the destination item and the image data of the icon corresponding to the destination item are acquired.

  The display control unit 53 generates animation display data for displaying an animation of dragging and dropping the icon of the point item onto the icon of the destination item.

  That is, the display control unit 53 generates animation display data for displaying an image indicated by the image data of the icon corresponding to the point item together with the image of the pointer 87 at the position on the screen of the icon corresponding to the point item. Further, the display control unit 53 arranges the image indicated by the image data of the icon corresponding to the point item together with the image of the pointer 87 at the position on the screen of the icon corresponding to the destination item. Animation display data to be moved to the image indicated by the icon image data corresponding to is generated.

  In step S <b> 21, the display control unit 53 causes the output unit 17, which is a display, to display an animation for dragging and dropping the point item icon onto the destination item icon using the animation display data, and the process ends.

  FIG. 5 is a diagram illustrating an example of an animation displayed on the output unit 17 that is a display. The animation 101 shows an operation of dragging and dropping the icon 85-3 corresponding to the point item to the icon 86-2 corresponding to the destination item. The animation 101 is displayed on the window 81.

  At the beginning of the animation 101, together with the same image as the pointer 87, the same image as the icon 85-3 corresponding to the point item is displayed on the icon 85-3 on the screen (the same position as the icon 85-3). The Next, the same image as the pointer 87 and the same image as the icon 85-3 are displayed on the icon 86-2 (the same position as the icon 86-2) corresponding to the destination item. To the same image.

  In the animation 101, an arrow 102 indicating the same image as the pointer 87 and the movement of the same image as the icon 85-3 may be displayed.

  The destination item may be an object, for example, an area.

  The animation 103 shows an operation of dragging and dropping the icon 85-3 corresponding to the point item to the area 83 corresponding to the destination item. The animation 103 is displayed on the window 81.

  At the beginning of the animation 103, the same image as the pointer 87 and the same image as the icon 85-3 corresponding to the point item are displayed on the icon 85-3 on the screen. Next, the same image as the pointer 87 and the same image as the icon 85-3 are moved to the same image as the region 83 displayed on the region 83 corresponding to the destination item.

  In the animation 103, an arrow 104 indicating the movement of the same image as the pointer 87 and the same image as the icon 85-3 may be displayed.

  In this case, the animation 101 or the animation 103 is displayed so as to be distinguishable from the window 81. For example, the same image as the pointer 87 and the same image as the icon 85-3 are displayed discretely (position and time are displayed in a discrete manner), or displayed semi-transparently.

  Further, in the animation 101 or the animation 103, an image showing the drag and drop effect may be displayed. For example, when an instance icon is displayed in the region 83 and an instance corresponding to the item 54-3 is generated by dragging and dropping the icon 85-3 to the region 83, the instance icon is displayed at the end of the animation 103. The same image may be displayed in the area 83.

  In the animation, the display of the same image as the icon of the destination item may be omitted.

  In this way, when an icon is pointed to satisfy a predetermined condition, a drag and drop animation is displayed. Thereby, it is possible to inform the user whether or not a drag-and-drop operation is possible simply and quickly.

  The user can know at a glance whether or not a desired target can be dragged and dropped by the displayed animation. There is no need to perform operations such as scrolling as in the help screen displayed in characters.

  When an image showing the drag-and-drop effect is displayed in the animation, it is not necessary to guess the process to be executed, and the user can surely know the drag-and-drop effect.

  In addition, since the combinations of the point item and the destination item are thinned out, the animation is displayed only for the representative combination. By doing in this way, it is prevented that many similar animations are displayed, and the display of animation does not become complicated. As a result, the user can know whether or not the drag-and-drop operation can be performed more quickly and reliably.

  FIG. 6 is a block diagram showing another configuration of a program executed on the personal computer. In the personal computer, the application program 121 and the OS 42 are executed. 6, the same parts as those shown in FIG. 2 are denoted by the same reference numerals, and the description thereof is omitted.

  The application program 121 includes a determination unit 51, a display control unit 53, a movement source movement destination specifying unit 141, an item manager 142, and items 161-1 to 161-8.

  The application program 121 applies various processes to the items 161-1 to 161-8. The application program 121 displays an animation indicating a drag-and-drop operation when a predetermined icon on the screen is designated by a pointer.

  The movement source movement destination identifying unit 141 identifies the movement source and the movement destination from the state of the object that is the movement source and the movement destination held in the item manager 142. The item manager 142 holds the state of the object that is the movement source and the movement destination.

Items 161-1 to 161-8 are objects made of data. Items 161-1 to 161-8 correspond to objects on the screen, respectively.

  Hereinafter, the items 161-1 to 161-8 are simply referred to as items 161 when it is not necessary to distinguish them individually.

  The number of items 161 is not limited to eight and can be any number.

  Next, another process of displaying the drag and drop animation will be described with reference to the flowchart of FIG. Since each of step S51 and step S52 is the same as each of step S11 and step S12 of FIG. 3, the description is abbreviate | omitted.

  In step S <b> 53, the movement source movement destination specifying unit 141 inquires of the item manager 142 about the movement destination item that is the movement destination item 161 to be dragged and dropped. That is, in step S <b> 53, the movement source movement destination specifying unit 141 inquires the item manager 142 about the movement destination item based on the ID supplied from the determination unit 51.

  The item manager 142 holds information on a destination item such as an item ID that identifies the destination item.

  When the item manager 142 is inquired about the destination item, the item manager 142 notifies the item ID for specifying the destination item. In step S54, the source destination specifying unit 141 receives the destination item from the item manager 142. Get the item ID to be identified

  In step S55, the movement source movement destination specifying unit 141 inquires of the item manager 142 whether the movement is possible based on the selected item ID.

  In step S <b> 56, the movement source movement destination identification unit 141 acquires a response indicating whether or not movement is possible from the item manager 142.

  For example, if the destination item specified by the selected item ID has been edited by another user at that time, the item manager 142 transmits a response indicating that the item cannot be moved, so step S56. The movement source movement destination specifying unit 141 acquires a response indicating that movement to the movement destination item specified by the selected item ID is not possible (cannot be moved).

  For example, if the destination item identified by the selected item ID is not occupied by another user at that time, the item manager 142 sends a response indicating that the item can be moved, In S <b> 56, the movement source movement destination identification unit 141 acquires a response indicating that movement to the movement destination item identified by the selected item ID is possible (moveable).
