It is the figure which showed an example (display example 1) of a mode that a drawing object is displayed. It is a flowchart of a display of a drawing object. It is the figure which showed an example (display example 2) of a mode that a drawing object is displayed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a configuration diagram of a drawing object display system according to the present embodiment.

  The drawing object display system 1 displays a drawing object, which is a handwritten character or figure, on a display unit generally called a white board, which is generally large, and is shared by many users, for example.

  For example, the display unit is configured to overlap with a touch panel that is an input unit used for a user to draw a drawing object by handwriting.

  The drawing object display system 1 generates and saves drawing data corresponding to a drawing object drawn by hand, and selects and displays drawing data corresponding to a user operation when displaying the drawing data.

  The drawing object display system 1 includes an input unit 11 used by a user to draw a drawing object by hand, an input processing unit 12 that generates drawing data corresponding to the drawing object drawn by hand, and drawing data stored therein. The data management unit 13 to be displayed, the display unit 14 to display the drawing object corresponding to the drawing data, the display processing unit 15 to display the drawing object on the display unit 14, and the display operation used for the display switching operation of the drawing object Part 16.

  The display unit 14 is configured to overlap with a touch panel that is the input unit 11, for example. The display operation unit 16 is configured by, for example, a mouse wheel that is an input device.

  The input processing unit 12 includes a counter 121 therein, and assigns the order attribute corresponding to the counter 121 and the initial value of the display attribute to the drawing data. The display attribute is either a visible attribute for visualizing the drawing data or an invisible attribute for making the drawing data invisible.

  The display processing unit 15 selects drawing data based on the display position information 151 included therein and the display switching direction of the drawing object, and sets only the display attribute of the drawing data to the visible attribute.

  Here, the drawing object display system 1 is configured to include the input unit 11, the input processing unit 12, the data management unit 13, the display processing unit 15, the display unit 14, and the display operation unit 16. 1 may be configured to connect them via a network.

  FIG. 2 is a diagram illustrating an example of how a drawing object is drawn by the user.

  First, in step 1, the user A draws a black circle at his / her position or a drawing object group OB1 of a map on the input unit 11 using, for example, a pen.

  Next, in step 2, the user A draws a drawing object group OB2 such as an ellipse or the like indicating the sentence “Is there no mark on this side?” And its position.

  Next, in step 3, for example, the user B draws a drawing object group OB3 such as a black circle at a signal position as a mark, a “signal present” sentence, and an arrow.

  Next, in step 4, the user A draws a drawing object group OB4 such as a sentence “Is there a postbox in the middle?”.

  Next, in step 5, for example, the user C draws a drawing object group OB5 such as a black circle at the position of the postbox or a sentence “There are fine”.

  FIG. 3 is a flowchart for generating drawing data corresponding to such a drawing object, assigning an attribute, and saving the drawing data.

  Here, an operation when drawing data is not stored in the data management unit 13 and a plurality of drawing data is stored in the data management unit 13 will be described.

  For example, when the user starts drawing a drawing object using a pen or the like (S1), the input processing unit 12 first resets the counter 121 to “1” (S3).

  If the user finishes drawing the drawing object corresponding to one drawing data (S5), for example, if one drawing data corresponds to only one drawing object, the pen moves away from the touch panel, or 1 When one drawing data corresponds to two or more drawing objects and the “write execution button” explicitly displayed on the touch panel is pressed with the pen, the input processing unit 12 displays only one such drawing. Drawing data corresponding to the object or one or more drawing objects is generated (S7). The drawing data only needs to have sufficient information to display the drawn drawing object at the drawn position.

  Next, the input processing unit 12 assigns an order attribute corresponding to the counter 121 and an initial value (for example, a visible attribute) of a predetermined display attribute to the generated drawing data, and the drawing data is assigned to the data management unit 13. (S9).

  Here, for example, if the counter 121 is “1”, the input processing unit 12 includes the order attribute “1” or “layer1”, and if the counter 121 is “2”, the order attribute is “2” or “layer2”. A number order attribute is added so that it includes.

  Alternatively, for example, if the counter 121 is “1”, the input processing unit 12 includes the order attribute “1”, that is, “layer A”, and if the counter 121 is “2”, the order attribute is “2”, that is, “layer B”. An alphabetical order attribute is given so as to include.

  Next, the input processing unit 12 adds “1” to the counter 121 (S11).

  Next, the input processing unit 12 determines whether or not the user has started drawing the next drawing object using a pen or the like (S13).

  For example, if drawing of the next drawing object is started (S13: YES), the control proceeds to step S5, and if drawing of the next drawing object is not started within a predetermined time (S13: NO), A series of processing ends.

  FIG. 4 is a diagram illustrating an example of stored drawing data.

  As shown in FIG. 4, each drawing data D is stored in the same XML file. Here, each drawing data D corresponds to one drawing object. Each drawing data D includes an order attribute N including “layer1” indicating the order and a display attribute V including “visible” indicating the visible attribute.

  FIG. 5 is a diagram illustrating an example of how a drawing object is displayed (display example 1).

  First, when the user scrolls the mouse wheel, instructs the start of display, and scrolls the wheel down twice, only the display attributes of the drawing data to which the first, second, and third order attributes are assigned are visible attributes. Thus, the corresponding drawing object groups OB1, OB2, and OB3 are displayed.

  Subsequently, when the user scrolls down the mouse wheel, only the display attributes of the drawing data to which the order attributes of No. 1, No. 2, No. 3, and No. 4 are given become visible attributes, and each corresponding drawing object group OB1. , OB2, OB3, and OB4 are displayed. That is, a drawing object “Is there a postbox in the middle?” That belongs to the drawing object group OB4 appears.

  Subsequently, when the user scrolls the mouse wheel down, only the display attributes of the drawing data to which the order attributes of No. 1, No. 2, No. 3, No. 4, and No. 5 are given become visible attributes, and corresponding drawing Objects OB1, OB2, OB3, OB4, and OB5 are displayed. That is, the drawing object “Okay,” belonging to the drawing object group OB5, three black circle drawing objects indicating the position of the post box appear.

  Subsequently, when the user scrolls the mouse wheel upside down, only the display attributes of the drawing data to which the order attributes of No. 1, No. 2, No. 3, and No. 4 are assigned again become visible attributes, and the corresponding drawing. A group of objects is displayed. In other words, the drawing object “Nice” belonging to the drawing object group OB5 is deleted.

  Subsequently, when the user further scrolls the wheel of the mouse, only the display attributes of the drawing data to which the No. 1, No. 2 and No. 3 order attributes are added become visible attributes, and the corresponding drawing objects are displayed. The That is, the drawing object “Is there a postbox in the middle?” Belonging to the drawing object group OB4 is deleted.

  FIG. 6 is a flowchart when the drawing object is reproduced, that is, displayed as described above.

  For example, when the user scrolls the mouse wheel and gives an instruction to start display (S21), the display processing unit 15 first resets the display position information 151 to “1” (S23).

  Next, the display processing unit 15 selects the drawing data to which the order attribute corresponding to the number below the current display position information 151 is selected in the data management unit 13, and sets the display attribute of the drawing data to the visible attribute. (S25).

  Next, the display processing unit 15 reads only the drawing data to which the visible attribute is given from the data management unit 13 and displays all the drawing objects corresponding to the drawing data on the display unit 14 based on the drawing data. (S27).

  Next, the display operation unit 16 determines whether or not the user has scrolled the mouse wheel up or down, that is, whether or not the user has instructed the display switching of the drawing object (S29).

  When the mouse wheel is scrolled up or down, that is, when the user gives an instruction to switch the display of the drawing object (S27: YES), the display operation unit 16 notifies the display processing unit 15 of the scroll direction. The display processing unit 15 subtracts “1” from the display position information 151 if the up scroll is notified and the display position information 151 is “2” or more. 1 "is added (S31), and the process returns to step S25.

  On the other hand, if the mouse wheel has not been scrolled up or down within a predetermined time, that is, if the user has not instructed the display switching of the drawing object (S29: NO), the series of processing ends.

  Thus, for example, as shown in FIG. 5, when the current display position information 151 is “3”, only the display attributes of the drawing data to which the first, second, and third order attributes are assigned are visible attributes. Thus, only the corresponding drawing object groups OB1, OB2, and OB3 are displayed.

  When the current display position information 151 is “4”, only the display attributes of the drawing data to which the order attributes of No. 1, No. 2, No. 3, and No. 4 are assigned become visible attributes, and each corresponding drawing object is displayed. Only the groups OB1, OB2, OB3, OB4 are displayed.

  When the current display position information 151 is “5”, only the display attribute of the drawing data to which the order attributes of No. 1, No. 2, No. 3, No. 4, and No. 5 are assigned becomes the visible attribute and corresponds. Only the drawing object groups OB1, OB2, OB3, OB4, and OB5 are displayed.

  FIG. 7 is a diagram illustrating an example of how a drawing object is displayed (display example 2).

  First, when the user scrolls the mouse wheel to instruct display start, only the display attributes of the drawing data to which the first, second, and third order attributes are assigned become the visible attributes, and each corresponding drawing object group OB1. , OB2 and OB3 are displayed.

  Subsequently, when the user scrolls the mouse wheel down, only the display attributes of the drawing data to which the first, third, and fourth order attributes are assigned become the visible attributes, and the corresponding drawing object groups OB1, OB3, OB4 is displayed. That is, the drawing object belonging to the drawing object group OB2 “there is no mark on this side” is deleted, and the ellipse drawing object indicating the position is erased, and the drawing object belonging to the drawing object group OB4 “is a postal post?” Appears.

  Subsequently, when the user scrolls down the wheel of the mouse, only the display attributes of the drawing data to which the first, fourth, and fifth order attributes are assigned become visible attributes, and corresponding drawing object groups OB1, OB4, OB5 is displayed. In other words, the drawing object “with signal” belonging to the drawing object group OB3 and the drawing object indicated by the arrow indicating the position thereof are deleted, and the drawing object belonging to the drawing object group OB5 “may be fine” and three black circles indicating the position of the post box are deleted. A drawing object appears.

  Subsequently, when the user scrolls the mouse wheel upside down, only the display attributes of the drawing data to which the order attributes of No. 1, No. 3, and No. 4 are added become visible attributes, and the corresponding drawing objects are displayed. Is done. That is, a drawing object “with signal” belonging to the drawing object group OB3 and a drawing object with an arrow indicating the position appear, and the drawing object “nice” belonging to the drawing object group OB5 and three black circles indicating the position of the postbox The drawing object is deleted.

  Subsequently, when the user scrolls the mouse wheel up, only the display attributes of the drawing data to which the No. 1, No. 2 and No. 3 order attributes are assigned become visible attributes, and the corresponding drawing objects are displayed. . That is, a drawing object belonging to the drawing object group OB2 “There is no mark on this side” and an ellipse drawing object indicating the position appears, and the drawing object belonging to the drawing object group OB4 “has a post box?” Is deleted. .

  In order to reproduce or display the drawing object in this way, processing similar to the flowchart of FIG. 6 is performed.

  However, in step S25, the display processing unit 15 causes the data management unit 13 to select the order attribute corresponding to No. 1, the order attribute corresponding to the number obtained by adding “1” to the current display position information 151, and the current display position. Drawing data to which the order attribute corresponding to the number obtained by adding “2” to the information 151 is selected, and only the display attribute of the drawing data is made visible.

  Thus, for example, as shown in FIG. 7, when the current display position information 151 is “1”, only the display attributes of the drawing data to which the first, second, and third order attributes are assigned are visible attributes. Thus, only the corresponding drawing object groups OB1, OB2, and OB3 are displayed.

  When the current display position information 151 is “2”, only the display attributes of the drawing data to which the first, third, and fourth order attributes are assigned become the visible attributes, and the corresponding drawing object groups OB1, Only OB3 and OB4 are displayed.

  When the current display position information 151 is “3”, only the display attributes of the drawing data to which the first, fourth, and fifth order attributes are assigned become the visible attributes, and the corresponding drawing objects OB1, OB4. , Only OB5 is displayed.

  In this embodiment, only the drawing object corresponding to the visible attribute is displayed, but “dark color” or “light color” is given as the display attribute, and the drawing object is displayed in dark color or light color accordingly. You may let them. Alternatively, “blinking display” or “always display” may be given as the display attribute, and the drawing object may be blinked or always displayed in accordance with this. Alternatively, “thick line” or “thin line” may be given as a display attribute, and the drawing object may be displayed with a thick line or a thin line according to this.

  That is, in step S25, the display processing unit 15 displays a display attribute (“blinking display” as described above) indicating that the drawing object should be emphasized with respect to the drawing data to which the order attribute corresponding to the display position information 151 is assigned. Or “thick line”) and display attributes (“always display” or “thin line” as described above) indicating that the drawing object should not be emphasized to other drawing data. In step S27, The drawing data is read out from the data management unit 13 regardless of whether or not the drawing data is given the order attribute corresponding to the display position information 151, and the drawing object corresponding to the drawing data is selected based on the drawing data. What is necessary is just to display on the display part 14 according to the display attribute provided to drawing data.

  In this embodiment, the display switching instruction is performed using the mouse wheel. However, this may be performed by operating the touch panel.

  Therefore, according to the drawing object display system 1 according to the present embodiment, the drawing object corresponding to the drawing data to which the order attribute corresponding to the display position information 151 is given is displayed or displayed according to the display attribute. The above problem (1) can be solved, that is, only a specific drawing object can be displayed or highlighted. Further, an order attribute is given to the drawing data, and the display position information 151 is updated by an operation on the display operation unit 16. By displaying the drawing object corresponding to the drawing data to which the order attribute corresponding to the updated display position information 151 is given, the problem (2) can be solved, that is, the display of the drawing object can be stopped halfway, The display can be changed in the direction of going back in time, and the above problem (3) can be solved, that is, the previous drawing. Even if there is a large gap from the writing object at a time until the writing of the next drawing object occurs, it is possible to quickly display the drawing object.

  A computer program for causing a computer (or a plurality of computers connected via a network) to function as the drawing object display system 1 is a computer-readable recording such as a semiconductor memory, a magnetic disk, an optical disk, a magneto-optical disk, or a magnetic tape. It can be recorded on a medium and can be widely distributed by being transmitted through a communication network such as the Internet.
