Description

  The present invention provides a presentation support system and a presentation support method for supporting a presentation performed by a speaker for an audience, a presentation device used in the system, and a control method for the presentation device. Related to the control program.

  A conventional presentation support system executes presentation software such as PowerPoint (registered trademark) on a computer used by a speaker, and displays a screen of the presentation software on a projector connected to the computer. This is the most popular style.

  Recently, a presentation support system has been proposed in which each computer of a listener can be connected to a network and information can be exchanged between the speaker and the listener via the network.

  For example, you can monitor the progress of a presentation over time and compare the required progress with a pre-registered progress to give advice on whether the presentation is fast or slow, and write down notes attached to each slide. A technique has been proposed in which a speaker is notified by display (see Patent Document 1).

  In addition, conference participants can refer to conference materials distributed electronically using a computer connected to the network, and each participant can perform operations such as turning pages and writing notes on the conference materials. The operation history is collectively stored in the participant status database in real time, and the information is converted into the status information of each participant and presented to the presenter at the necessary timing. A technique has also been proposed in which presentations and discussions can be performed while accurately understanding the participants' understanding and interest (see Patent Document 2).

Further, there is a technique in which presentation data for display for presentation is converted into an image format that can be displayed by the audience device and sent in consideration of the characteristics of the audience device (see Patent Document 3). ).

<Operation of this embodiment>
Next, as operations of the present embodiment, operations of the listener PC 103, the server 105, and the speaker PC 102 used by the listener A will be described with reference to the flowchart of FIG.

I. Operation of Audience PC 103 First, the operation of the audience PC 103 will be described.

  When the listener A performs a predetermined operation on the listener PC 103 when participating in the conference, the listener PC 103 notifies the server 105 of the listener characteristic information via the LAN 107 (step S801).

  The listener characteristic information is described in an XML-based format as shown in FIGS. FIG. 8A shows an example of the listener characteristic information of the listener A, and the <sex> element, the <age> element, and the <language> element represent gender, age, and language used, respectively. Furthermore, the <field> element represents the specialized field of the listener. In the example of FIG. 8A, the listener A shows details in the fields of speech synthesis, speech recognition, natural language processing, Web technology, and XML. The <disability> element represents information on the disabled person of the listener. In the example of FIG. 8A, the listener A is visually impaired. Moreover, the example of FIG.8 (b) has shown the listener characteristic information of another listener B. FIG.

  After step S801, the listener's PC 103 checks whether or not to receive the voice output text from the server 105 until there is an input that signifies the end of the conference, such as a predetermined operation by the listener A (step S805). When received (step S802), the received voice is synthesized (step S803) and a synthesized sound is output (step S804).

  Here, the audio output text is obtained by converting the content included in the presentation data by the speaker for audio output, as will be described later. Thereby, the listener A who is visually impaired can grasp the contents of the presentation data by voice.

II. Operation of Speaker PC 102 Next, the operation of the speaker PC 102 will be described.

  On the speaker PC 102, the speaker performs presentation data created in advance using predetermined software. In the present embodiment, as shown in FIG. 9, the presentation data is structured such that each slide is described in HTML, and each HTML file is accompanied by a metadata file in which metadata related to the contents is described in XML. It shall be.

  When the presentation data is executed by predetermined software, the slide1. The slide described in html has a display as shown in FIG. 10 and is displayed on the screen of the LCD 507 of the speaker PC 102 and the projector 101. When the speaker clicks on the word “next” on the screen display shown in FIG. Move to the slide described in html.

  This software constantly checks whether or not the integrated listener characteristic information, which is data obtained by integrating the listener characteristic information of each listener participating in the conference, has been transmitted from the server 105 (step S813). If so, it is stored (step S814). In the present embodiment, it is assumed that the integrated listener characteristic information is simply a collection of all the audience characteristic information as shown in FIGS.

  On the other hand, when the slide is moved, such as when the lecturer clicks the word “next” in the screen display shown in FIG. 10 (including the case where the first slide is displayed at the start of the presentation) (step S815). In order to convert the sound into a voice for the visually handicapped person, an HTML file that is display data of the current slide is transmitted to the server 105 as the conversion source data (step S816).

  Subsequently, support information for supporting the presentation is generated (step S817). The support information compares the audience's field of expertise with the content of each slide and advises the speaker whether the slide should be explained in detail or briefly. The support information generation unit 202 generates support information. The support information generation unit 202 compares the metadata attached to the target slide with the integrated listener characteristic information.

  The target slide is slide1. In the case of html, the accompanying metadata is meta1. xml. When the content of each <item> element included in the <keywords> element in this is compared with the content of each element in the <field> element in FIG. 8A included in the integrated listener characteristic information, “sound” Since it is known that “recognition” and “speech synthesis” match, it is determined that the listener A has expertise regarding the contents of this slide. On the other hand, when compared with the integrated listener characteristic information of FIG. 8B, since there is no coincidence, it is determined that the listener B does not have expert knowledge regarding the contents of this slide.

  If there are only two listeners (listeners A and B), the “specialty coincidence”, which is the ratio of the listeners who have specialized knowledge regarding the contents of this slide, is calculated as 50%. The support information generation unit 202 refers to a table as shown in FIG. 11 using the degree of special coincidence as a key, and extracts support information corresponding to the degree of special coincidence 50% “Let's give this slide a normal explanation.” . Then, the text is synthesized with speech (step S818), and a synthesized sound is output (step S819).

  In addition, the target slide is slide2. In the case of html, the accompanying metadata is meta2. xml. When this is compared with the integrated listener characteristic information, the degree of special agreement becomes 100% by the same method, so the support information is “Let's explain this slide lightly” from the table of FIG. .

  Subsequently, an HTML file which is display data of this slide is displayed (step S820) (displayed on the LCD of the speaker PC 102 and the screen of the projector 101). The speaker can obtain the support information while giving a presentation by listening to the output sound of step S819 through, for example, an earphone or headphones, and can determine how to explain the slide.

III. Operation of Server 105 Next, the operation of the server 105 will be described.

  The server 105 checks whether or not the listener characteristic information is sent from the listener PC (103 or 104 in this example) (step S806), and if it is sent, it is managed by the listener characteristic information management unit 401. The integrated listener characteristic information is updated by reflecting this in the integrated listener characteristic information (step S807), and the integrated listener characteristic information is notified to the speaker PC 102 (step S808). In the present embodiment, the reflection to the integrated listener characteristic information is simply added to the collection of the listener characteristic information of each listener.

  Further, the server 105 checks whether or not the slide HTML file transmitted from the speaker PC 102 in step S816 has been received (step S809), and if received, converts the HTML file into voice output text. (Step S810). If a visually impaired person is present among the listeners, the voice output text is transmitted to the listener's PC (step S811). Which listener is visually impaired can be determined from the <disability> element in each listener characteristic information included in the integrated listener characteristic information. Unless there is any termination condition (step S812), the process returns to step S806.

  For example, HTML is analyzed, the word “heading” is used for the contents of the <h1> tag, the word “item” is used for the contents of the <ul> tag, and the <a> tag is used. The content of the slide is supplemented with the word “hyperlink”, and the content of the slide is converted so that it can be easily understood by voice. slide1. FIG. 12 shows an example in which the contents of html are converted into text for voice output.

  As described above, according to the present embodiment, the lecturer can make a presentation without waste and lacking in accordance with the specialized field of the audience, and the audience can sufficiently present the contents of the presentation even if there is a visual impairment. I can grasp it.

[Second Embodiment]
