Description

  The present invention relates to a graphics dialogue apparatus and a graphics dialogue program for performing dialogue by drawing.

With the development of the Internet, a dialogue system in which a plurality of users interact with each other through a network has been developed (see, for example, Patent Document 1). According to such an interactive system, a large number of users can interact with each other through the Internet by inputting sentences using a keyboard of a personal computer. It is also possible to save the contents of the dialogue as data and search by a desired term.
JP 2002-82894 A

  However, in actual face-to-face meetings or lectures, for example, while drawing on a whiteboard, explanations are given while adding functions such as emphasis, denial, and question to the contents of the drawing. For example, emphasis is expressed by enclosing a figure with a circle, negative is expressed by attaching a cross to the figure, and a question is expressed by drawing a question mark near the figure.

  On the other hand, various drawing tools for drawing with a computer have been developed. According to the drawing tool, various diagrams can be easily drawn, and the diagrams can be corrected and the diagram data can be stored.

  By applying such a drawing tool to the dialogue system, it is considered that not only text but also dialogue by drawing becomes possible.

  However, when a conventional drawing tool is used in a dialogue system, it is difficult to give functions such as emphasis, denial, and question to the drawing contents. In addition, when the drawing content is stored as data, the drawing target cannot be searched based on the function.

  Also, if you have a conversation while drawing, you understand the meaning of the drawing contents during the conversation, but if you do not understand the process of generating the figure by looking at the figure drawn later, you will not understand the meaning of the figure There are many cases. However, it is inefficient from a time and labor point of view to regenerate the entire diagram generation process later.

  An object of the present invention is to provide a graphics interaction apparatus and a graphics interaction program capable of easily understanding each other and efficiently reproducing desired drawing contents based on functions.

  On the shared electronic whiteboard 2 of FIG. 4, a drawing window 201, an input button 202, a search button 203, a join button 204, a save button 205, a color button 206, an end button 207, function selection buttons 211 to 220, a search condition designation window 230 and a reproduction number designation window 231 are displayed.

  The input button 202, the search button 203, the combination button 204, the save button 205, the color button 206, the end button 207, and the function selection buttons 211 to 220 are collectively referred to as operation buttons. The user can select each operation button by pressing each operation button on the screen with the electronic pen 4.

  In the drawing window 201, drawing objects and function drawings drawn by the user of the shared electronic whiteboard 2 are displayed, and drawing objects and function drawings drawn by other users of the shared electronic whiteboard 2 are displayed.

  The input button 202 is used for selecting an input process, and the search button 203 is used for selecting a search process. The input process is a process for the user to draw on the shared electronic white board 2. The search process is a process for extracting a drawing object having a desired function from drawing information stored by the user. Details of the input process and the search process will be described later.

  The combination button 204 is used to combine a plurality of drawing objects into one drawing object. The save button 205 is used to save a relationship between a drawing object drawn in the drawing window 201 and a function assigned thereto as drawing information in a file. The color button 206 is used to select a color when drawing on the shared electronic white board 2. The end button 207 is used to end all the processes.

The search condition designation window 230 is used to set a search condition for search processing. The reproduction number designation window 231 is used for designating the number of drawing objects to be reproduced and displayed before and after the drawing object retrieved by the retrieval process.

  Although not shown in FIG. 4, the function drawing of FIG. 3 may be displayed together with the function selection buttons 211 to 220.

  FIG. 5 is a flowchart showing the overall processing of the graphics dialogue program executed by the CPU 21 of the shared electronic white board 2 of FIG. The overall processing of the graphics dialog program will be described below with reference to FIG.

  The CPU 21 determines whether or not the input button 202 has been pressed by the user (step S1). When the input button 202 is pressed, the CPU 21 executes input processing to be described later (step S2).

  If the input button 202 is not pressed, the CPU 21 determines whether or not the search button 203 has been pressed by the user (step S3). When the search button 203 is pressed, the CPU 21 executes a search process to be described later (step S4).

  If the search button 203 is not pressed in step S3, the CPU 21 executes another process (step S5).

  Thereafter, the CPU 21 determines whether or not the end button 207 has been pressed (step S6). If the end button 207 is not pressed, the process returns to step S1 and the processes of steps S1 to S6 are repeated. When the end button 207 is pressed, all the processes are ended.

  6 and 7 are flowcharts showing an input process (step S2 in FIG. 5) in the graphics dialogue program executed by the CPU 21 of the shared electronic white board 2 in FIG. Hereinafter, the input process of the graphics interactive program will be described with reference to FIG. 4, FIG. 6, and FIG.

  The user draws on the shared electronic white board 2 using the electronic pen 4. A continuous line segment drawn at the time of drawing is called a stroke. The time interval between strokes is called a drawing pose (non-drawing section). A plurality of strokes having a drawing pose of 400 milliseconds or less are regarded as one drawing object. The user can set and change the stroke color by pressing the color button 206.

  The CPU 21 stores the input time, coordinates, and color of the stroke drawn on the shared electronic white board 2 by the user in the RAM 23 as drawing data (step S11). Further, the CPU 21 generates a drawing object based on the plurality of strokes and the drawing pose of the drawing data (step S12).

  For example, when the drawing pose between the stroke ST1 and the stroke ST2 drawn in the drawing window 201 of FIG. 4 is 400 ms or less, the drawing object OB1 is generated by the stroke ST1 and the stroke ST2. Similarly, various drawing objects OB2 to OB11 shown in FIG. 4 are generated.

  Next, the CPU 21 determines whether or not a drawing object has been selected by the user (step S13). The user can select a drawing object by pressing the drawing object area in the drawing window 201 using the electronic pen 4.

  When the drawing object is selected, the CPU 21 determines whether or not the combining button 204 has been pressed by the user (step S14).

  If the join button 204 has not been pressed, the process returns to step S13 to determine again whether or not the drawing object has been selected by the user (step S13).

  When the drawing object is selected, the CPU 21 determines whether or not the combining button 204 has been pressed by the user (step S14).

  When the user selects a plurality of drawing objects, the processes in steps S13 and S14 are repeated.

  When the join button 204 is pressed in step S14, the CPU 21 joins the selected drawing objects (step S15). Thereby, a plurality of drawing objects are regarded as one drawing object. For example, the drawing objects OB9 and OB10 generated in the drawing window 201 of FIG. 4 are combined and regarded as one drawing object OB20.

  When one drawing object is selected in step S13 and the combining button 204 is pressed in step S14, the drawing objects are not combined.

  If the user does not select a drawing object in step S13, the process proceeds to step S16.

  Thereafter, the CPU 21 determines whether or not a function is selected by any of the function selection buttons 211 to 220 (step S16). In this case, the user presses any one of the function selection buttons 211 to 220 using the electronic pen 4 to affirm, deny, indicate (pronounically), emphasize, question (yes-no), question (who), Any one of a question, a question, a question, a question, a question, and a question can be selected.

  If no function is selected by the function selection buttons 211 to 220, the process returns to step S11.

  When a function is selected by any of the function selection buttons 211 to 220, the CPU 21 determines whether or not the range of the drawing object has been designated (step S17). In this case, the user can specify the whole or a partial range of the desired drawing object using the electronic pen 4. If the drawing object range is not designated, the CPU 21 waits until the drawing object range is designated.

  When the range of the drawing object is designated, the CPU 21 gives the function selected in step S16 to the drawing object (step S18). Further, the CPU 21 displays the function drawing corresponding to the function on, near or around the designated range of the drawing object (step S19).

  For example, when the function of question is selected by pressing the function selection button 216 in FIG. 4 and the range of the drawing objects OB2 and OB3 drawn in the drawing window 201 is designated, the drawing object A function drawing F1 is displayed in the vicinity of OB2 and OB3.

  When the negative function is selected by pressing the function selection button 212 in FIG. 4 and the range of the drawing object OB5 drawn in the drawing window 201 is designated, the function is displayed on the drawing object OB5. Drawing F2 is displayed.

  Further, when the function “what” is selected by pressing the function selection button 218 in FIG. 4 and the range of the drawing object OB6 drawn in the drawing window 201 is designated, the drawing object OB6 is displayed. A function drawing F3 is displayed in the vicinity.

  In addition, when the function selection button 211 in FIG. 4 is pressed and an affirmative function is selected and the range of the drawing object OB8 drawn in the drawing window 201 is designated, a function is displayed around the drawing object OB8. A drawing F4 is displayed.

  Next, the CPU 21 stores the relationship between the drawing object and the function in the RAM 23 (step S20).

  Thereafter, the CPU 21 determines whether or not the save button 205 has been pressed by the user (step S21). If the user has not pressed the save button 205, the process returns to step S11 and the processes of steps S11 to S21 are repeated.

  When the save button 205 is pressed by the user, the CPU 21 saves the relationship between all the drawing objects and functions of the drawing window 201 in FIG. 4 as drawing information in a file (step S22). In this case, the described function is given to the drawing object to which the function is not given. The file is stored in the external storage device 26 of FIG.

  FIG. 8 is a flowchart showing a search process (step S4 in FIG. 5) in the graphics dialogue program executed by the CPU 21 of the shared electronic white board 2 in FIG. Hereinafter, the graphics interactive program search process will be described with reference to FIGS. 4 and 8. FIG.

  First, the CPU 21 determines whether or not an input period and a function are specified as a search condition in the search condition specification window 230 of FIG. 4 (step S31).

  Any past period can be designated as the input period. Functions include affirmation, denial, indication (pronoun), emphasis, question (yes-no), question (how), question (how), question (where), question (where) and question (where) Either of them can be specified. In this case, the user can specify these functions from a pull-down menu (not shown).

  For example, in the search condition designation window 230 of FIG. 4, January 1, 2005 to January 31, 2005 is designated as an input period, and emphasis is designated as a function.

  When the search condition is not specified in the search condition specifying window 230, the CPU 21 waits until the search condition is specified in the search condition specifying window 230.

  When the search condition is specified in the search condition specifying window 230, the CPU 21 determines whether or not the specified function is a description (step S32).

  If the designated function is not a description, the CPU 21 searches for a drawing object in the file stored in the external storage device 26 and its function based on the designated input period and function (step S33).

  Next, the CPU 21 displays a list of searched drawing objects and functions on the shared electronic white board 2 (step S34). As a result, among the drawing objects drawn within the specified input period, the drawing objects to which the specified function is given are displayed together with the functions.

  If the function specified in step S32 is a description, the CPU 21 searches for a drawing object in the file stored in the external storage device 26 and its function based on the specified input period and function (step S35). ).

  Next, the CPU 21 displays a list of searched drawing objects on the shared electronic white board 2 (step S36). As a result, a list of drawing objects that are narrative drawing drawn within the designated input period is displayed.

  Next, the CPU 21 determines whether or not a drawing object has been selected from the list by the user (step S37). If no drawing object is selected, the process waits.

  If a drawing object is selected, it is determined whether or not the number of drawing objects to be reproduced is designated by the user in the reproduction number designation window 231 (step S38). In this case, the number of drawing objects to be reproduced represents how many drawing objects drawn before and after the drawing object selected by the user are displayed.

  When the number of drawing objects to be reproduced is designated in the reproduction number designation window 231, the CPU 21 draws the selected drawing object and the corresponding function drawing and the designated number of drawing objects before and after the drawing object and the corresponding drawing object. The function drawing is extracted from the file (step S39).

  Thereafter, the CPU 21 reproduces and displays a drawing history including the extracted drawing object and function drawing (step S40). For example, in the reproduction number designation window 231 of FIG. 4, 5 is designated as the number of drawing objects to be reproduced before the selected drawing object, and 5 is designated as the number of drawing objects to be reproduced later. In this case, the drawing object and function drawing drawn five times before the selected drawing object to the drawing object and function drawing drawn five times after the selected drawing object are reproduced and displayed in the drawing time order.

  As described above, since a function is given to a desired drawing object and a function drawing is displayed in association with the drawing object, the user can interact with other users by drawing. This facilitates mutual understanding among a plurality of interlocutors.

  In addition, since the relationship between the assigned function and the drawing object is saved in the file, it becomes possible to efficiently search for the drawing object based on the function. Thereby, desired drawing contents can be reproduced efficiently.

  Further, an input period can be further specified as a search condition for searching for drawing objects stored in a file. As a result, the corresponding drawing object is retrieved from the file based on the designated function among the drawing objects within the designated input period. Therefore, the user can easily reproduce the drawing contents in a desired input period based on the function.

  Furthermore, since the selected drawing object is reproduced and displayed together with the function drawing, the user can easily reproduce the conversation contents by the past drawing based on the function.

  In addition, the drawing object selected by the user and the designated number of drawing objects before or after the drawing object are reproduced and displayed in time order. As a result, the user can easily reproduce the content of the dialog by drawing in the past desired time based on the function.
