  In FIG. 1, the presentation support system 10 includes a presenter terminal 12, a listener terminal 14, and a server 16. The presenter terminal 12 and the listener terminal 14 are connected to the server 16 via a known communication network 18 such as the Internet or a LAN.

  The presenter terminal 12 is a terminal used by a presenter who makes a presentation using the presentation support system 10. In the present embodiment, a known notebook personal computer is used as the presenter terminal 12. On the other hand, the listener terminal 14 is a terminal used by a listener who listens to a presentation using the presentation support system 10. In the present embodiment, a known tablet personal computer having a touch panel display is used as the listener terminal 14.

  The server 16 is provided with a communication unit 20, a storage unit 22, and a control unit 24. The communication unit 20 is connected to the presenter terminal 12 and the listener terminal 14 via the communication network 18, and transmits / receives information to / from the connected terminals. The storage unit 22 stores various information such as a control program and control data, a presentation support program, and presentation reservation information and identification information used when the support program is executed.

  The control unit 24 reads information from the storage unit 22 and drives and controls each unit of the server 16 based on the read information. In addition, when the support program is started, the control unit 24 controls the display 12a of the presenter terminal 12 and the display 14a of the listener terminal 14 based on the support program, and displays various screens on the displays 12a and 14a. Display.

  The support program starts and ends when the presenter terminal 12 accesses the server 16, logs in by entering a pre-registered user name and password, and then inputs an activation instruction and termination instruction to the server 16. it can. When the support program is activated, an initial screen is displayed on the presenter terminal 12. Various tags such as reservation, reservation change, and presentation execution are displayed on the initial screen, and the presenter can operate the presenter terminal 12 to select one of these tags.

  When a reservation tag is selected, an input screen for entering the title and start date / time of the presentation to be reserved is displayed. By entering information (title and date / time) according to this input screen, a new presentation can be reserved. it can. When the reservation is completed, the reserved presentation is given an identification number for distinguishing it from other presentations, and the assigned identification number is notified to the presenter terminal 12.

  When the reservation change tag is selected, an input screen for inputting the identification number of the reserved presentation is displayed. When the identification number is input, the reservation content of the presentation corresponding to the identification number can be changed. When a presentation execution tag is selected, an input screen for inputting an identification number of a reserved presentation is displayed. When an identification number is input, a presentation support process corresponding to the identification number is started.

  As shown in FIG. 2, when the support process is started, the control unit 24 displays the main window 30 and the setting tag 32 on the display 12 a of the presenter terminal 12. The main window 30 displays materials such as slides used by the presenter in the presentation. The display of the main window 30 can be freely switched by operating the presenter terminal 12.

  When the setting tag 32 is selected, a menu screen for performing various settings is displayed. Then, by operating the presenter terminal 12 according to this menu screen, various settings can be made, the support process can be terminated, and display or non-display of a sub window 40 (see FIGS. 7 to 9) described later can be selected.

  When the support process is started, the server 16 can be accessed from the listener terminal 14, and the listener operates the listener terminal 14 to access the server 16 and inputs the identification number of the presentation to participate. Can participate in presentations. It should be noted that the method of accessing the server 16 and the identification number of the presentation are known to the presenter who made the reservation, for example, by notifying each listener using e-mail or verbally at the presentation venue. Can be communicated to listeners

  As described above, when the listener participates in the presentation by inputting the identification number, the control unit 24 displays a link window (not shown) on the display 14 a of the listener terminal 14. In the link window, the same screen as the main window 30 is displayed. When the display of the main window 30 is switched, the display of the link window is switched in synchronization therewith.

  As illustrated in FIG. 3, the control unit 24 monitors the display of the main window 30 during the support process, and switches the display of the link window in synchronization with the display when the display is switched. Thus, the control unit 24 functions as a listener screen control unit. Note that the main window and the link window need not be completely linked. For example, a part of the image may be enlarged or reduced by an operation from the listener terminal. Further, materials previously displayed in the link window may be displayed retrospectively by an operation from the listener terminal.

  Notes can be written on the material displayed in the link window. When writing, for example, the type of writing such as a memo or a question can be specified. For example, the listener starts up the menu with the link window displayed, selects writing, and then designates the type of writing to shift to a writable state, and then performs a touch operation on the display 14a. It is possible to write a memo or a question directly on the displayed material by hand. Thus, the display 14a functions as an input means by handwriting.

  As shown in FIG. 4, the control unit 24 constantly monitors the presence / absence of writing during the support process. When the writing is performed, the control unit 24 performs a collection process and a totaling process. As shown in FIG. 5, in the collection process, the writing is stored as it is in the storage unit 22 as image data. In addition, the control unit 24 associates this image data with information indicating the material (such as what page of the material was written) displayed when the writing was performed, and the type of writing (memo Or the question), and writing related information including information indicating the writing date and time is stored in the storage unit 22.

  As shown in FIG. 6, in the aggregation process, the material is divided into a plurality of areas, it is determined which area has been written, and the number of writing and the number of writing for each area are calculated. For example, if the document is in HTML format, this document can be analyzed by code analysis to determine how the text and images in the document are arranged (area divided). Based on the above, area division may be performed for each paragraph, image, and photograph. Also, if the material is not pre-partitioned as in the above-mentioned HTML, it is possible to divide the sentence and the image by well-known image analysis, or to change the paragraph of the sentence according to the concentration state of the information (the degree of character collection). What is necessary is just to identify and partition for every paragraph.

  The determination as to which area has been written may be made, for example, by determining that writing has been made to the area having the highest degree of overlap with writing or the area closest to writing. Also, the number of writes is calculated by incrementing the value of the counter that counts the number of writes of the same type among the counters that count the number of writes in this area each time a new write is made. do it.

  As described above, the collected and aggregated information on writing can be confirmed by selecting the setting tag 32 on the presenter terminal 12 and displaying the sub window 40. For example, as shown in FIG. 7, the sub window 40 is displayed smaller than the main window 30 in the corner of the display 12a immediately after display, and the display area can be enlarged by clicking the sub window 40.

  In the subwindow 40, a normal analysis screen 50 shown in FIG. 8 and a detailed analysis screen 52 shown in FIG. 9 are displayed. These screens 50 and 52 can be switched by selecting the normal analysis tag 60 and the detailed analysis tag 62 displayed on each screen 50 and 52.

  In FIG. 8, the normal analysis screen 50 shows the result of the collection process, and the writing itself written in the material displayed in the link window is displayed over the written material for each type. It is a thing. The tags 50a, 50b, and 50c are displayed on the normal analysis screen 50. When the tag 50a is selected, all types of writing are displayed over the material. When the tag 50b is selected, the writing written as a memo is displayed on the material. When the tag 50c is selected, the writing written as a question is displayed over the material.

  In FIG. 9, the detailed analysis screen 52 shows the result of the tabulation process. Each area of the material is displayed in different colors according to the number of writings for each type, and each numerical value indicating the number of writings for each type is displayed. It is described in the area. Tags 52a, 52b, and 52c are displayed on the detailed analysis screen 52. When the tag 52a is selected, color-coded display and numerical values are displayed according to the number of all types of writing, and when the tag 52b is selected, a memo is displayed. Color-coded display and numerical values are displayed according to the number of written data written as, and when the tag 52c is selected, color-coded display and numerical values are written according to the number of written data written as questions. .

  In FIG. 9, the material is divided into six areas 70, 71, 72, 73, 74, and 75. There is no type of writing corresponding to the selected tag in area 70, and 2 in area 71. In the example, there are one write, five writes in area 72, seven writes in area 73, twelve writes in area 74, and fifteen writes in area 75.

  In FIG. 9, the area where there is no writing (namely, area 70) is not colored, the area where writing is 1-3 (namely, area 71) is colored in pale yellow, and the area where writing is 4-6 (namely, area 72). ) Is colored yellow, the area of writing 7-9 (ie area 73) is colored light orange, the area of writing 10-12 (ie area 74) is colored orange and the area of writing 13 or more (Ie, area 75) shows an example of coloring in red.

  As described above, the control unit 24 always monitors the presence / absence of writing during the support process, and performs the above-described collection process and aggregation process each time writing is performed. Based on the results of the collection process and the totalization process, the display screens of the sub-window 40 (the normal analysis screen 50 and the detailed analysis screen 52) are updated in real time (see FIG. 4). Thus, the control unit 24 functions as presenter screen control means.

  As described above, the presentation support system 10 transmits the listener's reaction to the presenter in an intuitively easy-to-understand format by observing the normal analysis screen and the detailed analysis screen during the presentation. In addition, since the writing can be performed by handwriting, the listener's reaction is more easily transmitted to the presenter. As a result, it is possible to prevent problems such as the presenter moving forward with the conversation even though the listener does not understand.

  In addition, this invention is not limited to the said embodiment, A detailed structure can be changed suitably. For example, in the above-described embodiment, an example in which a presentation support system is configured from a presenter terminal, a listener terminal, and a server has been described. However, the server may be eliminated. In this case, a function corresponding to the control unit and storage unit of the server may be provided in the presenter terminal, and the presenter terminal and the listener terminal may be directly connected without using the server.

  In the above-described embodiment, an example in which a notebook personal computer is used as the presenter terminal has been described. However, the presenter terminal has a communication function for communicating with the server, a display function for displaying various screens, and an operation function for performing various operations. However, the present invention is not limited to a notebook personal computer, and various known terminals such as a desktop personal computer, a tablet personal computer, a smartphone, and a PDA can be used.

  Moreover, although the said embodiment demonstrated the example using a tablet-type personal computer as a listener terminal, the listener terminal should just have a function which can input a memo by handwriting in addition to the function of the presenter terminal mentioned above. Therefore, it is not limited to a tablet-type personal computer, and various known terminals such as a desktop personal computer, a notebook personal computer, a smartphone, and a PDA can be used.

  In the above embodiment, the material displayed in the link window has been described as an example for browsing only, but the material displayed in the link window may be stored in the listener terminal. Furthermore, for example, attribute information indicating whether or not the presenter terminal allows storage is registered in advance for each material (or each part of the material), and the material (or part of the material) permitted to be stored is registered. May be stored in the listener terminal, and the material (or part of the material) that is not permitted to be stored may be browsed only on the listener terminal.

  In the above-described embodiment, the example in which all the writings of the listener terminal are collected, aggregated, and transmitted (published) to the presenter terminal has been described. However, the type of writing (for example, private) is provided as the type of writing. The writing may not be disclosed to the presenter terminal by selecting private as the writing type.

  Further, the writing color may be selectable, and the writing type may be distinguished by the color. Furthermore, as the type of writing, the writing color is changed according to the type of writing, for example, writing is made yellow when a memo is selected, and writing is made blue when a question is selected. Also good. Conversely, the type of writing may be changed simply by designating the color for writing.

  In the above-described embodiment, an example has been described in which materials are divided into areas for each screen (or one page), but the material area dividing method can be changed as appropriate. For example, an animation composed of a series of images is divided as one area, each image constituting the animation is divided as one area, or each image constituting the animation is further divided into a plurality of areas. It may be divided.

  In addition, a method for determining which area is written can be changed as appropriate. For example, characteristic symbols included in writing, such as arrows, lead lines, and balloons, may be detected using a technique such as image analysis, and it may be determined that writing has been performed on the area indicated by these symbols. .

  Furthermore, a characteristic symbol included in writing may be detected using a technique such as image analysis, and the type of writing may be automatically determined. In this case, for example, based on whether a question mark is detected, whether an exclamation mark or an exclamation mark is detected, whether an underline or a highlight is added to the sentence, etc. What is necessary is just to determine the kind of.

  In addition, the screen displayed in the sub-window is not limited to the above-described embodiment as long as the listener's reaction can be easily transmitted to the presenter.For example, in the normal analysis screen, the display of the writing to be displayed on the material according to the number of writing is performed. The color may be changed. Of course, each area is distinguished, and the writing color displayed on the material may be different between the area with much writing and the area with little writing. Furthermore, according to the number of writing, the writing display mode (lighting, blinking, blinking speed) displayed on the material may be changed.

  Similarly, on the detailed analysis screen, the display mode of each area and the display mode of numbers representing the number of writes displayed in each area may be changed according to the number of writes in each area. Furthermore, as the number of writing increases, the number representing the number of writing may be increased, or the thickness of the line of numbers may be increased. Further, although an example has been described in which a number representing the number of writing is displayed over the area, it may be displayed in the vicinity of the area.

  Further, in addition to the collected / aggregated results of writing, the number of listeners participating in the presentation may be displayed on the presenter terminal. The number of participants can be detected by the control unit monitoring new access or disconnection of the listener terminal. Of course, not only the current number of participants but also the number of midway participants and the number of midway participants may be displayed. In addition, a chart in which the number of participants is associated with the display on the main display such as the page number of the time and the document is displayed may be displayed.

  In addition, when participating in a presentation, the participants are asked to enter identification information (name, age, gender, employee number, membership number, etc.) to display in more detail what kind of participants are participating. Also good. Of course, the identification information of the participant such as the IP address of the listener terminal may be automatically acquired by the server or the presenter terminal. In addition, identification information of a scheduled participant may be registered in advance, and a notification that a scheduled participant is absent or an unscheduled participant has joined may be displayed.

  Furthermore, in the above-described embodiment, an example has been described in which the listener can participate in the presentation simply by inputting the identification number of the presentation. However, like the presenter (terminal), the listener (terminal) is also registered, and when participating in the presentation. In addition, a registered ID or password may be input. Further, identification information of participants who are allowed to participate may be registered, and only registered participants may be allowed to participate in the presentation. This can improve security.

  In the above-described embodiment, the example of displaying the collected / aggregated result of writing (the normal analysis screen and the detailed analysis screen) on the presenter terminal has been described, but the present invention is not limited to this. The collection / aggregation result of writing (normal analysis screen or detailed analysis screen) may be displayed on the listener terminal. This is convenient because the listener can know the reactions of other listeners (the listeners can share the reactions).

  Furthermore, in the above-described embodiment, an example has been described in which a writing collection / counting result (a normal analysis screen or a detailed analysis screen) is displayed during a presentation, but the present invention is not limited to this. For example, the image data of the writing itself and the writing related information are stored in association with the display of the main window at the time of writing (eg, what page of the document was displayed). The transition of the display of the main window, the link window, and the sub window may be reproduced after the presentation ends. By doing this, it is possible to know the circumstances under which each writing was made (the time of writing and the screen of the main window that was displayed at that time (such as what page of the document was displayed)). It is possible and convenient to look back on the situation in the future.

  Of course, the presenter terminal may not only reproduce the state of the presentation after the end of the presentation, but also the listener terminal may be able to reproduce the state of the presentation after the end of the presentation. When reproducing the presentation state at the listener terminal, only the writing written by itself may be reproduced. Furthermore, the image data of the writing itself may also be stored in the listener terminal so that the writing of itself can be confirmed at any timing.

  Moreover, although the said embodiment demonstrated the example which can display two screens, a normal analysis screen and a detailed analysis screen, this invention is not limited to this. For example, only one of these may be displayed.

  In the above-described embodiment, the example is described in which the collection / aggregation is performed every time writing is performed, but the timing of collection / aggregation can be changed as appropriate. For example, collection / aggregation may be performed every time a displayed material is switched at regular time intervals. Similarly, the timing of reflecting the aggregation / collection results (update of the normal analysis screen and the detailed analysis screen) can be changed as appropriate.
