Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)
FIG. 1 is a diagram illustrating an example of a hardware configuration of the conference system. As shown in FIG. 1, the conference system 1 includes a display device 11, an input device 12, an information processing device 13, and a recording device 14. The conference system 1 of the present embodiment has two conference rooms, an in-house conference room X and an external conference room Y. In the conference room X and the conference room Y, a display device 11, an input device 12, and an information processing device 13 are installed, respectively. The information processing device 13 in each conference room is connected to the information processing device 13 in another conference room via a communication circuit. Therefore, the information processing device 13 in each conference room can display the same information on the display device 11 installed in each conference room synchronously.

  Recording data 15 is recorded in the recording device 14. In the recorded data 15, for example, a plurality of conference data used in the conference is recorded. The conference data includes one or more slides displayed on the display device 11. In addition, attribute information such as time information, place information, configuration information, and main theme information is added to the conference data. The time information is time information when conference data is displayed on the display device 11 or when an operation from a conference participant (user) is performed on the conference data. The location information is location information where the conference data is used, and is, for example, an identifier of a conference room (internal conference room X, external conference room Y). The configuration information is information on an identifier representing one or more slides constituting the conference data. The main theme information is information representing an attribute of the type of meeting such as a regular meeting or a business meeting.

  FIG. 2 is a diagram illustrating an example of a configuration of a display device, an input device, and an information processing device installed in a conference room. In FIG. 2, the display device 11 is a display or the like. The display device 11 displays a slide 44 as conference data. Here, the slide is composed of one or more objects. The object has attributes such as a stroke group, an image, text, and a moving image. Here, the stroke group refers to a state in which strokes input by the user are grouped, and details thereof will be described later. The slide 44 shown in FIG. 2 is composed of a car graphic 54 having an object attribute as an image and a character “car” 53 having an object attribute as a stroke group. Here, the character “car” 53 is an object that is input and displayed by the user using the input device 12.

  The input device 12 is an electronic pen or the like. For example, the user inputs “car” on the display surface of the display device 11 using the input device 12 during the meeting. Then, the information processing device 13 detects the stroke information of the stroke (input) one character at a time, and displays the character “car” 53 on the display device 11 one character at a time based on the stroke information. In this way, the information processing device 13 can display the stroke as if the user is directly drawing on the display device 11.

  Here, the stroke information is information including stroke graphics (stroke coordinates), stroke speed, stroke length, stroke generator, and stroke time information for one stroke. The stroke graphic means the coordinates of the stroke. The stroke speed is the input speed of the stroke. The stroke length refers to the length of the stroke. The stroke generator is the name of the user who entered the stroke. The stroke time information refers to the stroke input operation time. One stroke refers to a drawing range input by one stroke or a range of one character. The character “car” 53 is composed of three characters, and is a group of strokes composed of three strokes. In this way, a group of strokes composed of a plurality of strokes is called a stroke group. The stroke group may be composed of one stroke. The generation of the stroke group is performed by a CPU of the information processing apparatus 13 described later.

  The user can issue an instruction to display the recording data 15 recorded in the recording device 14 on the display device 11 via the input device 12. The input device 12 is not particularly limited as long as it can be freely input by the user, such as a mouse or a digitizer.

FIG. 3 is a diagram illustrating an example of a hardware configuration of the information processing apparatus. In FIG. 3, the information processing apparatus 13 includes a CPU 31, a ROM 32, a RAM 33, a storage device 34 such as a hard disk, and a communication interface 35. Each component is connected via a bus 36. The CPU 31 controls each component connected to the bus 36.
The CPU 31 performs processing described later by reading the program recorded in the storage device 34 or the ROM 32 into the RAM 33 and executing it. The ROM 32 stores a program that is first executed by the CPU 31 when the information processing apparatus 13 is activated. The RAM 33 is used as a work memory when the CPU 31 executes a program, and the processed data and the like are temporarily recorded therein. The storage device 34 stores a program according to the present embodiment, character authentication data to be described later, and the like. The communication interface 35 connects the display device 11, the input device 12, the recording device 14, and other information processing devices.

FIG. 4 is a flowchart illustrating an example of processing of the information processing apparatus.
In step S <b> 301, the user instructs the information processing device 13 to display the slide included in the conference data on the display device 11 among the recorded data 15 recorded in the recording device 14. The CPU 31 of the information processing device 13 displays the instructed slide.

  Next, in step S <b> 302, the user inputs a stroke via the input device 12 in order to supplement the displayed slide with, for example, an object displayed on the slide. The CPU 31 detects the stroke information of the input stroke and displays the stroke on the display device 11. The CPU 31 groups one or more strokes to generate a stroke group. When there are a plurality of slides to be displayed, the user instructs to display the plurality of slides sequentially, and inputs a desired stroke for each displayed slide.

  Next, in step S303, the CPU 31 records, on the recording device 14, the slide displayed on the display device 11 in step S301, the objects constituting the slide, the stroke input in step S302, and the like. Further, the CPU 31 records slide information in the recording device 14 in association with the slide. The slide information includes an identifier of an object constituting the slide, an attribute of the object constituting the slide, stroke group information when the object attribute is a stroke group, slide sub-theme information, and the like. The CPU 31 records these information on the recording device 14 in association with each slide.

  Here, the stroke group information refers to the number of strokes, stroke group length, stroke group density, stroke group speed, stroke group graphic (stroke group coordinates), stroke group creator, and the like. The number of strokes refers to the number of strokes constituting a stroke group. The stroke group length is the total length of each stroke. The stroke group density refers to the ratio of the stroke group to the slide, and will be described in detail later. The stroke group speed is the average input speed of each stroke. The stroke group graphic (stroke group coordinates) refers to the position coordinates of each stroke. The stroke group creator is the name of the user who entered the stroke group. Of the stroke group information, the number of strokes is acquired in the next step.

  Next, in step S304, the CPU 31 performs a process of acquiring stroke group information (number of strokes) for each slide of conference data recorded in the recording device 14 (acquisition of stroke group information).

Next, in step S305, the CPU 31 determines the importance of the slide based on the acquired stroke group information.
Details of the processes in steps S304 and S305 are shown in FIG.

  Next, in step S306, the CPU 31 collects the slides determined to be important slides (importance is set to 1) in the determination of the importance level of the slides, and outputs them as a file. Further, when displaying the conference data as a list, the CPU 31 determines that the display of the slide determined to be an important slide (importance is 1) is not an important slide (importance is 0). The display is different from the display (display control). Here, the display of the slide includes a case where a thumbnail of the slide is displayed.

  FIG. 5 is a diagram showing an example of slides included in the conference data recorded in the recording device. The conference data shown in FIG. 5 includes four slides 41, 42, 43, and 44. In addition, the slide 43 and the slide 44 include an object whose attribute is a stroke group.

FIG. 6 is a diagram for explaining an example of a method for calculating the number of strokes in the stroke group information. CPU31 calculates the stroke of the area | region which can be extracted with a rectangle as a stroke number. In the case of characters, the number of strokes is calculated by one character. In the case of characters other than characters, the number of strokes is calculated by the number of strokes. For example, the CPU 31 compares the stroke information of the input stroke with the character authentication data stored in the storage device 34 to determine whether the character is a character. The CPU 31 determines that the characters are similar when the two are similar, and determines that the characters are other than the characters when they are not similar.
The CPU 31 calculates the number of strokes for each slide. FIG. 6 illustrates a process in which the CPU 31 calculates the number of strokes using the slide 43 and the slide 44 including the stroke group of FIG.

In FIG. 6, the slide 43 includes an object 51 and an object 52. Here, the object 51 is a stroke input by the user, and constitutes a stroke group composed of one stroke. The object 52 is an image.
First, for the slide 43, the CPU 31 detects the attributes of the object 51 and the object 52 from the slide information of the slide 43. From the slide information of the slide 43, the CPU 31 determines that the attribute of the object 51 is a stroke group, and determines the attribute of the object 52 is an image.
Next, the CPU 31 calculates the number of strokes 55 of the object. The object 51 has one stroke composed of one stroke. Therefore, the CPU 31 calculates the number of strokes as one. Next, the object 52 has an image attribute and has no stroke. Therefore, the CPU 31 calculates the number of strokes as zero.

In FIG. 6, the slide 44 includes an object 53 and an object 54. The slide 44 is the same as the slide described in FIG. Here, the object 53 is a plurality of strokes input by the user and constitutes a stroke group. The object 54 is an image.
Next, for the slide 44, the CPU 31 detects the attributes of the object 53 and the object 54 from the slide information of the slide 44. From the slide information of the slide 44, the CPU 31 determines that the attribute of the object 53 is a stroke group and determines the attribute of the object 54 as an image.
Next, the CPU 31 calculates the number of strokes 55 of the object. The object 53 is a character and the number of characters is three. Therefore, the CPU 31 calculates the number of strokes as three. Next, the attribute of the object 54 is an image and there is no stroke. Therefore, the CPU 31 calculates the number of strokes as zero.

  FIG. 7 is a flowchart showing in detail an example of the processing of steps S304 and S305 in the flowchart of FIG. First, in step S601, the CPU 31 determines whether or not there is a stroke group in the attribute of the object constituting the slide, based on the slide information associated with the slide for the evaluation target. If it is determined that there is no stroke group, the CPU 31 proceeds to step S605. If it is determined that there is a stroke group, the CPU 31 proceeds to step S602.

In step S602, the CPU 31 calculates the number of strokes for the slide to be evaluated as described with reference to FIGS.
Next, in step S603, the CPU 31 compares the calculated number of strokes with a predetermined threshold value. As a result of the comparison, if the number of strokes is equal to or less than the threshold value, the CPU 31 proceeds to step S605. When it is larger than the threshold value, the CPU 31 proceeds to step S604. Note that the threshold value can be arbitrarily changed by a user setting for the information processing apparatus 13.

  In step 604, the CPU 31 determines that the slide to be evaluated is “important slide”, and sets the importance to 1, for example. In step S605, the CPU 31 determines that the slide to be evaluated is “an unimportant slide”, and sets the importance to 0, for example. The CPU 31 adds the importance information to, for example, slide information.

Next, the output process of step S306 in the flowchart of FIG. 4 will be described with reference to FIG. 8, FIG. 9, and FIG.
FIG. 8 is a diagram showing an example of a state in which a plurality of conference data as shown in FIG. 5 is recorded in the recording device. Each of the conference data 71 to 75 is composed of a plurality of slides. For example, the conference data 71 includes slides 76 to 79 and the like. In addition, the conference data 71 to 75 are collected by conference data used on different dates (dates) based on time information set in the conference data, for example. Further, each slide included in the conference data has sub theme information. The slides are divided into groups for each sub theme and recorded on the recording device 14.

FIG. 9 is a diagram illustrating an example in which a list of conference data is displayed in a tree diagram for each content of a conference.
As shown in FIG. 9, the CPU 31 displays a list of conference data including slides on the display device 11. Each meeting data has main theme information such as a regular meeting and a sales meeting. In the example of FIG. 9, a list of conference data related to the regular conference 81 is displayed from the conference data group recorded in FIG.

  A “regular meeting” 81 is displayed as the main theme at the left end of the conference data list. In addition, at the top of the list, the dates of “9/5”, “9/12”, “9/15”, “9/19”, and “9/30” are displayed. For example, in the conference data of FIG. 8, it is assumed that the conference data 71 has time information that is used on 9/5. It is assumed that the conference data 72 has time information that is used on 9/12. It is assumed that the conference data 73 has time information that is used on 9/15. Assume that the conference data 74 has time information that is used on 9/19. It is assumed that the conference data 75 has time information that is used on 9/30. CPU31 displays the date which is the time information which each meeting data has on the upper end of a list.

  At the right end of the conference data list, “whiteboard” 82, “format” 83, “plan” 84, and “search” 85 are displayed as sub-themes of conference data. For example, in the conference data 71 of FIG. 8, it is assumed that the slide 76 has sub-theme information “whiteboard”. Further, it is assumed that the slide 77 has sub-theme information “format”. It is assumed that the slide 78 has sub-theme information “plan”. It is assumed that the slide 79 has sub theme information “search”. CPU31 displays the sub theme information which a slide has on the right end of a list.

  Further, the CPU 31 classifies and displays slide groups included in the conference data for each sub theme. In FIG. 9, when there is a slide group that matches the sub theme in the conference data, the CPU 31 displays a display that the user can recognize, such as “■” or “◯”, at the place where the date and the sub theme intersect. Do. When there is no slide group that matches the sub theme in the conference data, the CPU 31 does not display at the location where the date and the sub theme intersect. Therefore, the user visually understands that, for example, the conference data used for 9/5 includes a slide having sub-theme information of “whiteboard”, “format”, “plan”, and “search”. be able to.

  Furthermore, in the list of FIG. 9, it is possible to easily search for important slides. That is, the CPU 31 displays the display of the group including the slide determined to be an important slide in the slide group matching the sub theme different from the display of the group not including the important slide (display control). . In FIG. 9, the CPU 31 displays a group including an important slide as “◯”, and displays a group not including an important slide as “■”. Further, the CPU 31 changes and displays the display size of “◯”, for example, according to the importance level of the important slide. Further, the CPU 31 may display the group including the most important slide so as to be written together with characters such as “important” 87 in addition to enlarging the group display. Further, the CPU 31 may perform highlighting such as changing the display color or displaying it thickly according to the importance of the important slide. In this way, the CPU 31 visualizes information input to the conference data using the characteristics obtained from the stroke group information for each slide. Thus, the user can quickly find a slide important for the user from the conference data group.

  FIG. 10 is a diagram illustrating an example of slide thumbnail display. For example, it is assumed that the user wants to browse important slides included in a group of slides that are conference data used on September 15 in the conference data list of FIG. In this case, for example, the user moves a pointer 88 such as a mouse so as to overlap a group of slides to be browsed in FIG. Then, as shown in FIG. 10, the CPU 31 displays a list of reduced images (thumbnail images) 91 to 94 of the slides included in the group superimposed on the pointer 88. At this time, the CPU 31 displays the thumbnails 93 and 94 of the slides determined to be important slides larger than the thumbnails 91 and 91 of the slides determined not to be important slides (display control). Further, as shown in FIG. 10, the CPU 31 displays the thumbnail of the slide with the largest number of strokes based on the number of strokes of the slide information of each slide, and displays the thumbnail of the slide with the smallest number of strokes slightly larger. .

(Second Embodiment)
In the first embodiment, only the process in the case of determining the reference of the slide importance degree determination process based on the number of strokes in the process of step S305 in the flowchart of FIG. 4 has been described. However, the determination of the importance is not limited to the case based only on the number of strokes. In the second embodiment, a process in the case where the importance of the slide is determined in combination using the number of strokes and the stroke group density in the process of step S305 in the flowchart of FIG. 4 will be described.

  FIG. 11 is a diagram illustrating an example of slide information in which the stroke group density is included in the stroke group information. Here, the stroke group density 101 is a value calculated by an area ratio between the area of one slide and the rectangular area of an object whose attribute is a stroke group. In the slide thumbnail list display as shown in FIG. 10, the CPU 31 compositely determines the number of strokes of information included in each slide and the stroke group density, and changes the display size of the slide thumbnails. indicate. For example, in FIG. 11, when the stroke group information that the slide 43 has and the stroke group information that the slide 44 has are determined in combination, the slide 44 has a larger number of strokes and stroke group density. Therefore, the CPU 31 determines that the slide 44 is more important than the slide 43, and displays, for example, a thumbnail 94 corresponding to the slide 44 larger than the thumbnail 93 for the slide 43 as shown in FIG.

(Third embodiment)
In the above-described embodiment, the process in the case where the standard of the slide importance level determination process is determined based on the number of strokes or the number of strokes and the stroke group density has been described. However, the criterion for determining the importance is not limited to these. The CPU 31 may use the number of strokes included in the stroke group information, the stroke group length, the stroke group density, the stroke group speed, the stroke group graphic information, the stroke group generator, and the like as the determination criteria.

  The determination of the importance level of the slide is not limited to the determination of whether or not the slide to be determined is important (that is, whether the importance level is 1 or 0). For example, the CPU 31 may set the importance level of the slide to be determined more finely. More specifically, the user sets thresholds in different ranges in the storage device 34 for each slide importance level. The CPU 31 determines which range of threshold values the threshold group information of the object included in the slide to be determined corresponds to among different threshold values. Then, the CPU 31 adds the importance corresponding to the corresponding threshold to the slide information of the slide, and changes the display size of the display related to the slide according to the importance as shown in FIG. 9 or FIG. Thereby, the user can identify the importance of a plurality of slides more efficiently. Note that the CPU 31 may perform highlighting such as changing the display color of the slide or displaying it thickly according to the importance.
