  The second communication unit 32 communicates with the communication unit 23 of the imaging device 20 by wire or wireless. The information processing apparatus 30 takes in audio data and image data acquired by the imaging apparatus 20 via the second communication unit 32.

  The GPS module 33 is a sensor that detects the position (for example, latitude and longitude) of the information processing apparatus 30. That is, when the information processing apparatus 30 is installed at the presentation venue, the GPS module 33 detects the location of the presentation venue.

  The memory 34 is a non-volatile memory (flash memory) or the like, and in addition to data necessary for carrying out the presentation, the venue communication audio data and image data received by the second communication unit 32 from the imaging device 20, the audio Stores data (table) for analyzing data and image data.

  FIG. 3 shows an example of data stored in the memory 34. As shown in FIG. 3, in the present embodiment, the projection document A, B, C... Of the presentation created in advance by the presenter is stored in the memory 34. These projection originals A, B, C,... Relate to the same subject as an example, but the contents of the projection manuscripts A, B, C,... Suppose that part or all of them are changed. For example, if a certain projection document is “explanation material regarding XX (for beginners)”, another projection document is “explanation material regarding XX (for advanced users)”.

  Further, as shown in FIG. 3, the memory 34 stores a face data table, a frequency table, and a word data table. The face data table stores feature points related to the human face, for example, feature points related to the shape of the eyebrows, eyes, nose, lips and the outline of the face. The face data table stores feature data and color data of feature points such as eyebrows, eyes, nose, lips, and contours for each age of each gender. The frequency table is a table that stores characteristic frequencies (basic frequencies) included in human speech for each gender and age. In the word data table, words in a language used in the country or region where the presentation is performed are registered. Further, it is assumed that keywords registered in advance by the presenter of the presentation are registered in the word data table. In addition, as a keyword, the word etc. in the material used for a presentation shall be registered, for example.

  The display 35 is a liquid crystal display or the like, and is used to display a projection original when a presenter makes a presentation.

  The output unit 36 outputs the same screen information as the screen information displayed on the display 35 to the projection device 40.

  The control unit 37 has a CPU and controls the entire processing of the information processing apparatus 30 in an integrated manner. In the present embodiment, the control unit 37 acquires information on the seat position where the viewer is seated from the seats in the venue based on the image data acquired via the second communication unit 32 (sitting position analysis). Further, the control unit 37 estimates the age group of viewers in the venue based on the image data and the face data table (age group analysis). Moreover, the control part 37 estimates the sex of the person who is uttering voice based on the audio | voice data acquired via the 2nd communication part 32, and a frequency table (gender analysis). Further, the control unit 37 detects keywords related to the presentation based on the voice data and the word data table (keyword analysis). And the control part 37 provides the information which supports a presentation with respect to a presenter based on the acquired, estimated, and detected information. Hereinafter, each analysis method performed by the control unit 37 will be described in detail.

(Sitting position analysis)
The seating position analysis is a process for determining whether each seat in the hall is in a seated state or an empty seat. In the seating position analysis, the control unit 37 acquires the image of the audience seat in the hall imaged by the imaging device 20, and compares it with a reference image of the audience seat (an image taken in the hall using the imaging device 20 before opening). Then, it is determined whether each seat is in a seated state or a vacant seat state. Since the seat where the luggage is placed may be determined to be seated, the control unit 37 performs face recognition using the face data table and specifies the position of the seat where the person is actually sitting. It may be.

  In the seating position analysis, for example, the control unit 37 divides the audience seats in the hall into a plurality of areas, and acquires the seating situation (sitting ratio) for each area. In addition, what is necessary is just to divide | segment an area | region on the basis of the front, back, upper side, center, lower side, 1st floor seat, 2nd floor seat, etc., for example. Further, each of the imageable areas of the plurality of imaging devices 20 may be associated with each divided area. The control unit 37 repeatedly acquires the seating situation (sitting rate) in a timely manner, and stores the seating situation (sitting rate) in the memory 34 in association with the time.

(Age group analysis)
Age group analysis is a process of detecting the face of a person from an image and estimating the age group of the detected person. In the age group analysis, the control unit 37 detects the face of the person using the image of the passenger seat taken by the imaging device 20 and the face data table. As an example of the face detection method, feature points are extracted from an image to detect a face region or the like. The feature points include end points of eyebrows, eyes, nose and lips, and face contour points (for example, the head vertex and the lower end point of the chin). The control unit 37 stores the detected face image in the memory 34. Then, the control unit 37 estimates the age group of the person based on the detected face image. In this case, the control unit 37 compares the feature and color of each feature point in the detected face image with the feature and color of each feature point of the face stored in advance in the face data table, Estimate the age group of people. As an estimation result, the control unit 37 stores information such as “20s” and “40s” in the memory 34 in association with the face image. A method for detecting a person's face from image data and a method for estimating a person's age group are also disclosed in Japanese Patent Application Laid-Open No. 2010-34685 filed earlier by the present applicant.

(Gender analysis)
The gender analysis is a process for estimating the gender of a person who is producing a sound from the sound data acquired by the imaging device 20. In this gender analysis, for example, when the basic frequency of the voice is in the range of 100 to 150 Hz, the control unit 37 is the adult male who is the voice and the basic frequency of the voice is in the range of 200 to 300 Hz. In this case, it is estimated that the person who uttered the voice is an adult female, and the person who uttered the voice is a child when the fundamental frequency of the voice is in the range of 350 to 400 Hz. A method for determining the gender of a person from audio data is also disclosed in Japanese Patent Application Laid-Open No. 2011-130317 filed earlier by the present applicant. The control unit 37 stores the number of times determined as “adult male”, “adult female”, or “child” in the memory 34.

(Keyword analysis)
The keyword analysis is a process of detecting a keyword related to the content of the presentation from the audio data acquired by the imaging device 20. In the keyword analysis, the control unit 37 detects a word included in the acquired voice data, and determines whether the detected word matches the keyword specified in advance by the presenter. If the detected word is a keyword, the keyword and the number of times the keyword is issued are stored in the memory 34.

  The projection device 40 is a projector, acquires information on an image output from the output unit 36 of the information processing device 30, and projects the image onto a screen. As illustrated in FIG. 2, the projection device 40 includes a projection control unit 41 and a projection unit 42. The projection control unit 41 is connected to the output unit 36 by wire or wirelessly, and causes the projection unit 42 to project an image acquired from the output unit 36 of the information processing apparatus 30.

  The projection unit 42 includes a light source, an illumination optical system, a light modulation element, a projection optical system, and the like. The light source is, for example, a lamp that emits light. The illumination optical system illuminates the light modulation element with the light beam emitted from the light source. The light modulation element is, for example, a liquid crystal panel, and generates an image to be projected on the screen. The projection optical system projects the light beam from the light modulation element toward the screen. The projection optical system includes a zoom lens that adjusts the size of an image to be projected and a focus lens that adjusts the focus position.

  Returning to FIG. 1, the information providing apparatus 50 is a server that operates a website, for example, and selects and provides information according to a request from the control unit 37.

  Next, processing (particularly processing of the control unit 37) of the presentation support system 100 configured as described above will be described in detail along the flowchart of FIG.

  4 and 5 are flowcharts showing processing by the control unit 37. The processing of FIGS. 4 and 5 is started when the venue for the presentation is opened. The presenter or the like may set an opening time in advance for the control unit 37, or at a stage when the presenting time comes, the presenter or the like may start a predetermined process for starting the processes of FIGS. The start button may be pressed. When the presentation venue is small, such as a company conference room or school classroom, the arrival of the first viewer at the venue can be detected from the image data and audio data of the imaging device 20. You may make it start the process of FIG.

  In step S <b> 1, under the instruction of the control unit 37, the imaging device 20 starts acquiring audio data and image data in the hall. The audio data and image data in the venue acquired by the imaging device 20 are transmitted to the control unit 37 and stored in the memory 34 by the control unit 37. Data acquisition by the imaging device 20 is continuously performed and continues until the presentation starts or is interrupted by the presenter or the like.

  Next, in step S <b> 2, the control unit 37 detects the position information of the information processing device 30 using the GPS module 33. The control unit 37 stores the detected position information in the memory 34.

  Next, in step S3, the control unit 37 acquires the seating state (sitting rate) of each seat based on the image data. In this case, the control unit 37 acquires the time transition of the seated state for each area in the hall (front of the first floor, rear of the second floor, etc.) and confirms from which area of the hall the seat is filled. .

  Next, in step S4, the control unit 37 estimates the expected degree of presentation. The control unit 37 estimates the degree of expectation of the presentation based on from which area the seat acquired in step S3 is filled. For example, if the seat is buried from the front area, it is considered that there are many viewers eagerly listening to the presentation. In such a case, the control unit 37 has a high expectation of the presentation. presume. On the other hand, if the seat is buried from the rear area, it is considered that the viewer does not expect much from the presentation. In such a case, the control unit 37 has a low expectation of the presentation. presume.

  Next, in step S5, the control unit 37 estimates the age group of the viewer (a specific viewer seated in front of the audience seat) shown in the image based on the image data obtained by imaging the front of the audience seat. That is, in step S5, the control unit 37 estimates the age group of enthusiastic viewers seated in front of the passenger seat. In this case, the control unit 37 detects the face of the person from the image data obtained by imaging the front of the passenger seat, the features and colors of the detected feature points of the face, and the features of the face stored in advance in the face data table. The age group of the detected person is estimated by comparing the features and colors of the points. At this time, in order not to overlap the same data, the face data of the person whose age group is estimated once is not acquired again. In addition, although it is preferable that there are a plurality of persons for estimating the age group, one person may be used if the age groups of a plurality of viewers cannot be estimated.

  Next, in step S6, the control unit 37 performs gender estimation and keyword detection of the recorded voice owner (viewer) based on the voice data recorded in front of the passenger seat. Here, the control unit 37 estimates the gender of the viewer (specific viewer) who sits in front of the passenger seat and wants to listen to the presentation eagerly based on the fundamental frequency included in the audio data. Moreover, the control part 37 detects the keyword relevant to a presentation from the conversation of the viewer who sits in front of a passenger seat.

  Next, in step S7, the control unit 37 selects a projection document and proposes the selected projection document to the presenter. The control unit 37 detects the location of the venue acquired in step S2, the expectation level of the presentation estimated in step S4, the age group of the viewer estimated in step S5, the gender of the viewer determined in step S6, and in step S6. A projection document is selected based on the presence or absence of a keyword.

  For example, when the location of the venue is in Japan, the control unit 37 selects a Japanese projection original, and when the location of the venue is the United States of America, the control unit 37 selects an English projection original. For example, when it is determined from the time transition of the seated state that the degree of expectation of the presentation is high, the control unit 37 selects a projection document with a more detailed explanation. Further, for example, when the main age group of viewers (specific viewers) is in their 40s and 50s, the control unit 37 has few explanations of matters that are considered to be detailed by seniors and For example, select a projection document with an increased explanation of items that seem to be sparse. For example, when the percentage of women included in the viewer (specific viewer) is large, the control unit 37 selects a projection document created with a female eye. Further, for example, when a large number of keywords related to the presentation are issued, it can be estimated that the viewer (specific viewer) has abundant knowledge about the contents of the presentation. Select a projection document. On the other hand, when almost no keywords related to the presentation are detected, it can be estimated that the viewer is not familiar with the contents of the presentation, so the control unit 37 selects a projection document for beginners. Note that the control unit 37 may select a document by combining the examples of selecting the projection document described here. In addition, the control unit 37 may select the projection document by giving priority to the age group, sex, and the like.

  The control unit 37 outputs the selected projection document on the display 35 and proposes it to the presenter. The control unit 37 may propose a plurality of projection originals to the presenter. In this case, the presenter selects one of the projection originals proposed on the display 35. Note that the reason for the proposal (for example, “because there are many women”, “because there are many 40s”, etc.) may be displayed on the display 35 together with a plurality of projection originals. As a result, the presenter can easily and appropriately select the projection document.

  Next, in step S8, the control unit 37 acquires a topic from the network 60 (for example, the information providing apparatus 50). In this case, the control unit 37 acquires the topic of time and the news near the venue based on the location information acquired in step S2 and information on the event as the topic to be acquired. In addition, when the percentage of women included in viewers sitting in front of the audience seats (specific viewers) is large, the control unit 37 may acquire topics related to beauty and fashion that are considered to be of interest to many women. Good. Moreover, the control part 37 may acquire the topic regarding a fashion etc. according to the age group of a meeting place. In addition, any one of the words acquired from the acquired audio data in the venue (for example, words frequently issued other than keywords related to the presentation) is searched on the network 60 as a search word, and a topic related to the word is acquired. May be.

  Next, in step S9, the control unit 37 waits until the presenter accepts the proposal when there is one proposed projection original, and when there are a plurality of proposed projection originals, the presenter Wait until a document is selected. When the proposal is accepted or when the projection document is selected, the control unit 37 proceeds to step S10. Since the presenter can also select a projection document other than the proposed projection document, the process proceeds to step S10 even when such a selection is made.

  In step S <b> 10, the control unit 37 displays the accepted or selected projection document on the display 35 and outputs it to the projection device 40.

  Next, in step S11, the control unit 37 executes a presentation. In this case, the control unit 37 performs processing such as page feed of the projection document in response to the presenter pressing a mouse button or a keyboard key. The control unit 37 starts counting the remaining time from the stage where the presentation is started to the scheduled end time of the presentation.

  Next, in step S12, the control unit 37 compares the scheduled presentation speed (degree of progress) with the current presentation speed (degree of progress), and determines whether or not the presentation time exceeds a predetermined time. Judging. If the determination here is affirmed, the process proceeds to step S13, and the control unit 37 displays the list of topics acquired in step S8 on the display 35 and provides it to the presenter. Thereafter, the process proceeds to step S14.

  On the other hand, if the determination in step S12 is negative, the process proceeds to step S14. In step S14, the control unit 37 determines whether or not the presentation is finished. Note that the control unit 37 may determine whether or not the presentation has ended based on, for example, whether or not the last page of the projection document has been reached. If the determination in step S14 is negative, the process returns to step S11, and the processes and determinations in steps S11 to S14 are repeated. On the other hand, if the determination in step S14 is affirmative, all the processes in FIGS.

  As described above in detail, according to the present embodiment, the second communication unit 32 inputs the audio data and image data acquired by the imaging device 20 to the control unit 37 prior to the presentation, and the control unit 37 37 acquires information related to the seating position of the viewer of the presentation based on each data, and the audio data and image data of the viewer (specific viewer) who sits in front of the audience seat at the presentation venue among the viewers. And get. As a result, the control unit 37 can acquire the characteristics of an enthusiastic viewer sitting in front of the passenger seat from the audio data and the image data.
