Description

  The present invention relates to a presentation support apparatus, a presentation support method, and a presentation support program. .

  In conventional presentations, it has been common to print the content to be presented on a transparent sheet and project it onto the screen using an overhead projector (OHP). In recent years, however, personal computers (PCs) and liquid crystals have been used. More and more work is done using projectors. When using a PC, graphics and moving images can be easily handled by the function of the presentation software, which is very convenient.

  Usually, the presenter understands the content of the presentation well, so it is often possible to make a presentation just by looking at the presentation slide projected on the screen without reading the scenario manuscript of the presentation content. When giving a presentation in a foreign language, such as a presentation at an international conference, it may be necessary to prepare a scenario manuscript in advance and present it while reading it. In this case, it is necessary to prepare to print the scenario manuscript on paper in advance, and if you present it with a scenario manuscript in hand, you will need to turn the scenario manuscript when switching the presentation slides. However, there are disadvantages that it is difficult to read the scenario manuscript, and it is difficult to know how far the scenario manuscript has been read due to tension.

  As a system for smoothly proceeding with the presentation, for example, Patent Document 1 proposes a system that can perform a predetermined operation such as page turning with an indicating tool possessed by an explainer. Patent Document 2 proposes a system in which operation units are provided on both sides of a display device.

In Patent Document 3, the created document is analyzed, and the analyzed document is converted into a presentation format and read out by speech synthesis, so that the presentation content and method can be confirmed at the same time as the preparation of the presentation manuscript. A system that can do this has been proposed.

  The presentation support device 16 is composed of, for example, a personal computer, and outputs a slide image (presentation image) having contents presented by the presenter 22 to the projector 14. The projector 14 enlarges and projects the slide image from the presentation support device 16 on the screen 12.

  The remote controller 20 is an operation device for switching slide images projected on the screen 12, and can perform operations such as specifying the next page, previous page, and page number, for example. When the presenter 22 operates the remote controller 20, a remote control signal corresponding to the operation content is transmitted to the presentation support device 16. The presentation support device 16 selects a slide image to be projected on the screen according to the received remote control signal, and outputs it to the projector 14. Thereby, the slide image projected on the projector 14 is switched.

  The audio signal of the speech of the presenter 22 is transmitted to the presentation support device 16 by the audio microphone 18, for example. The audio microphone 18 may be a wireless microphone or a wired microphone.

  In the presentation support device 16, speech recognition processing is performed based on the input speech signal of the presenter 22, and the presenter 22 utters a keyword corresponding to the slide image projected on the screen 12 based on the speech recognition result. If the voice is not spoken, a warning to that effect is given (details will be described later).

  FIG. 2 is a block diagram showing a schematic configuration of the presentation support apparatus 16. The presentation support apparatus 16 includes a voice input unit 30, a voice recognition unit 32, a display unit 34, an operation unit 36, a storage unit 38, a remote control light receiving unit 40, a communication unit 42, and a control unit 44 that controls each unit. Has been.

  The voice input unit 30 receives a voice signal from the voice microphone 18 and outputs it to the voice recognition unit 32. The voice recognition unit 32 performs voice recognition processing based on the voice signal from the voice input unit 30 and outputs character string data of the recognized voice. Note that the voice recognition method of the voice recognition unit 32 may be a method of recognizing the voice of a specific speaker or a method of recognizing the voice of an unspecified speaker. It is necessary to register the voice of a specific speaker.

  The display unit 34 includes a liquid crystal display and displays various images such as a slide image output to the projector 14.

  The operation unit 36 includes, for example, a keyboard, a mouse, a pointing device, and the like.

  The storage unit 38 stores various programs such as a presentation program for displaying a slide image on the display unit 34 and outputting the slide image to the projector 14, various data such as a slide image, a keyword table described later, and the like.

  The remote control light receiving unit 40 receives a remote control signal from the remote control 20 and outputs it to the control unit 44.

  The communication unit 42 is for outputting a slide image to the projector 14 and exchanging various data and control signals with the projector 14. The communication method between the communication unit 42 and the projector 14 may be wireless communication or wired communication.

  The slide image output from the presentation support device 16 to the projector 14 is configured to include a plurality of object images (partial images), for example, as shown in FIG. For example, the slide image P1 for the first page includes object images OBJ1, OBJ2, and OBJ3, and the slide image P2 for the second page includes object images OBJ4, OBJ5, and OBJ6. The object image includes a text image in addition to an image image such as a photograph or a figure.

  As described above, each slide image includes at least one object image. Therefore, the slide image data of the slide image is configured to include the object image data of the object image, and a presentation file is configured by the slide image data of each slide image. Each object image is given an object name, and the object image can be specified by the object name.

  In addition, when the presenter 22 explains each object image of the slide image projected on the screen 12, it may be necessary to explain important keywords related to the object image. For example, as shown in FIG. 3, the object image OBJ1 included in the slide image P1 is an important keyword for the keyword (character string) “A”, and similarly, the object image OBJ2 is an important keyword for “B”. . A plurality of keywords “D” and “E” may be included for one object image, such as the object image OBJ4 included in the slide image P2 of the second page, and a keyword such as the object image OBJ6 may be included. May not be included.

  The storage unit 38 stores a keyword table 50 relating to the correspondence between the keyword of each slide image and the object image as shown in FIG.

  As shown in FIG. 4, the keyword table 50 is data representing the correspondence relationship between the page number of the slide image included in the presentation file, the object name of the object image included in the slide image, the keyword, and the utterance flag.

  The control unit 44 determines whether or not the presenter 22 has uttered the keyword based on the character string data of the speech of the presenter 22 recognized by the speech recognition unit 32 and the keyword table 50. If the keyword is not spoken, the presenter 22 is warned by a method such as outputting an enlarged image of the object image corresponding to the keyword to the projector 14 and displaying it on the screen 12. Thereby, the presenter 22 can recognize that an important keyword is not explained, can prevent omission of explanation, and can easily grasp the progress of the presentation.

  Next, as an operation of the present embodiment, a control routine executed by the presentation support apparatus 16 will be described with reference to a flowchart shown in FIG.

  The control routine shown in FIG. 5 is executed when the presentation support apparatus 16 is instructed to read a presentation file and the presentation program is started.

  First, in step 100, the control unit 44 outputs slide image data of the first page of the slide image included in the presentation file to the projector 14 via the communication unit 42. As a result, an enlarged image of the slide image P1 of the first page is projected on the screen 12. The presenter 22 will explain the content with reference to the slide image P1 projected on the screen 12. The voice of the presenter 22 is picked up by the voice microphone 18 and input to the voice input unit 30.

  In step 102, it is determined whether or not the voice of the presenter 22 has been input to the voice input unit 30. If a voice is input, the process proceeds to step 104. If a voice is not input, the process proceeds to step 110.

  In step 104, the speech recognition unit 32 performs speech recognition processing on the speech signal input to the speech input unit 30 and outputs the speech signal to the control unit 44 as character string data.

  In the next step 106, the control unit 44 determines whether or not a keyword related to the slide image P <b> 1 projected on the screen 12 is uttered based on the character string data from the voice recognition unit 32 and the keyword table 50.

  Specifically, it is determined whether or not a keyword related to the slide image P1 projected on the screen 12 is included in the input character string data. In the case of the slide image P1 of the first page, by referring to the keyword table 50 shown in FIG. 4, it can be seen that three keywords “A”, “B”, and “C” are included. It is determined whether or not the character string data “A”, “B”, and “C” is included in the character string data thus obtained.

  If the keyword corresponding to the slide image projected on the screen 12 is included in the character string data input from the voice recognition unit 32, the process proceeds to step 108, and the utterance flag of the keyword is controlled. It is rewritten by the unit 44. Specifically, the control unit 44 rewrites the utterance flag shown in FIG. 4 to data indicating utterance (for example, “1”). Note that the utterance flag is set in advance to data (for example, “0”) indicating unspoken voice by default.

  Thus, by referring to the keyword table 50, it is possible to easily grasp whether or not the keyword is uttered.

  In step 110, the control unit 44 determines whether or not a remote control signal instructing page switching from the remote control 20 is received by the remote control light receiving unit 40. If page switching is instructed, the process proceeds to step 112. If page switching is not instructed, the process returns to step 102 and the same processing as described above is performed.

  In step 112, the control unit 44 determines whether there is an unspoken keyword among the keywords related to the slide image projected on the screen 12. That is, with reference to the keyword table 50 shown in FIG. 4, it is determined whether or not all of the keyword utterance flags relating to the slide image projected on the screen 12 have been uttered. For example, in the case of the slide image P1 of the first page, it is determined whether or not the utterance flags of the keywords ‘A’, ‘B’, and ‘C’ are all uttered.

  If there are unspoken keywords, the process proceeds to step 116. On the other hand, if there are no unspoken keywords, that is, if all the keywords related to the slide image projected on the screen 12 have been uttered, the process returns to step 100 and the slide image data of the slide image of the page instructed to switch is returned. Output to the projector 14. Thereby, the slide image projected on the screen 12 is switched.

  In step 116, warning processing is performed. Specifically, referring to the keyword table 50, the object name of the object image corresponding to the unspoken keyword is acquired, and the image data obtained by enlarging the object image data corresponding to the object name is output to the projector 14. As a result, the object image corresponding to the unspoken keyword is enlarged and projected onto the screen 12. As a result, the presenter 22 can easily recognize that the keyword is not explained, can prevent the omission of presentation, can support accurate presentation, and can grasp the progress of the presentation. it can.

  The warning method is not limited to this, and other methods may be used for warning. For example, a mark for calling attention may be displayed near an object image corresponding to an unspoken keyword.

  Further, in this embodiment, a case where a warning is given when an unspoken keyword is present when page switching is instructed has been described. However, a warning is given when the order in which keywords are spoken is different from a predetermined order. May be. For example, a term of utterance order is provided in the keyword table 50 shown in FIG. 4, or data of each row of the keyword table 50 is stored in advance according to the utterance order. Then, the order of the spoken keywords is confirmed, and if there is a keyword to be spoken before that keyword, the above warning processing is performed at that time. Thereby, it is possible to support the presentation to be performed more accurately and smoothly.

  Further, for example, when a scenario document for presentation is displayed on the display unit 34 of the presentation support device 16 and the presentation can be performed while viewing the document, a character string that matches the character string included in the scenario document is displayed. When speech recognition is performed, the color of the character string may be displayed on the display unit 34 with a color different from that of other character strings. Thereby, it is possible to easily grasp how far the announcement has been made.
