Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to information collecting systems and information collecting methods for providing information to members of the audience at theaters where movies and theatrical productions are presented, collecting information from the members of the audience, and compiling the information from the members of the audience. 
   2. Description of the Related Art 
   Theaters are very convenient venues for distributing agencies, production companies, and merchandise distributors, which present entertainment programs and sell related merchandise, to collect information from members of the audience as large groups of people typically gather at theaters to view movies, theatrical productions, and musical concerts. Hitherto, questionnaires have mainly been used to collect information such as feedback on the programs, and requests. At theaters, organizers of productions may provide members of the audience with information about other programs and related merchandise. For example, pamphlets, brochures, fliers are distributed, and posters and bills are posted. At movie theaters, commercials are screened prior to the presentation of feature films. 
   Collecting information using questionnaires takes time and labor, such as distribution and collecting of questionnaire forms and preparation of pens and pencils. For members of the audience, it is burdensome to fill out and submit questionnaire forms. As a result, the recovery rate is generally low. Also, the information which can be collected using this method is limited. Even when information is provided by distributing pamphlets, brochures, and fliers, by posting bills, and by screening commercials, it is impossible to satisfactorily provide more detailed, relevant information to members of the audience who become interested in a certain event or product because of the information provided in the theaters. It can be concluded that the conventional methods of providing information have been unsatisfactory. In theaters, merchandise such as pamphlets and posters are sold at concession stands. Carrying purchased merchandise home becomes an inconvenience. 
   SUMMARY OF THE INVENTION 
   Accordingly, it is an object of the present invention to provide an information collecting system for efficiently providing an audience member with more information and collecting information from the members of the audience. 
   Another object of the present invention is to provide an information collecting method for efficiently providing an audience member with more information and collecting information from the members of the audience. 
   In order to solve the foregoing problems, according to an aspect of the present invention, an audience information collecting system for providing information to an audience member at a venue where a performance including a movie or a theatrical production is presented and for collecting information from the audience member is provided. The audience information collecting system includes an audience terminal and an information collecting unit.

   DESCRIPTION OF THE PREFERRED EMBODIMENT 
   The present invention will become apparent from the following description of the preferred embodiment with reference to the accompanying drawings. 
     FIG. 1  shows the outline of an audience information collecting system according to an embodiment of the present invention. 
   An audience information collecting system  1  provides information to and collects information from members of the audience at a venue  10  such as a movie theater, a theater, a concert hall, or the like. The audience information system  1  includes an information collecting unit  11  for providing information and compiling collected information and audience terminals  12 ,  13 , and  14  for outputting information to members of the audience and receiving information input by the members of the audience. The information collecting unit  11  and the audience terminals  12  to  14  are connected to one another by a network  15  such as a local area network (LAN) installed in the venue  10 . The network  15  is capable of transmitting information at a high speed. The information collecting unit  11  includes a transmitter/receiver  111  for establishing a connection with the network  15  and transmitting and receiving information; a provided information storage unit  112  for storing information to be provided to an audience member; and a compiler  113  for compiling response information given by the audience member in response to the provided information. The audience terminal  12  includes a transmitter/receiver  121  for establishing a connection with the network  15  and transmitting and receiving information; a provided information output unit  122  for outputting provided information to an audience member; a personal information reading unit  123  for reading information from a recording medium having stored therein personal information of the audience member; and a response information input unit  124  for inputting response information given by the audience member in response to the provided information. The audience terminals  13  and  14  each have the same structure as that of the audience terminal  12 . The audience terminals  12  to  14  are provided at each seat in the venue  10 . The number of audience terminals corresponds to the number of seats and is not limited to three. 
   Audience information collecting systems  2  and  3 , each having the same structure as that of the audience information collecting system  1 , are provided in venues  20  and  30  all over the country. The audience information collecting systems  1  to  3  are connected, by a network  70  such as a public telephone circuit or the Internet, to computers installed at an information provider/collector  40 , a distributor  50 , and an audience member&#39;s home  60 . The information provider/collector  40  provides members of the audience at the venues  10  to  30  with information and collects response information such as feedback and requests from members of the audience. Specifically, for example, the information provider/collector  40  is a film distributor, a concert producer, or a company requested by the film distributor or the concert producer to provide and collect information. The distributor  50  is a company which sells merchandise related to a performance using the audience information collecting systems  1  to  3  at the venues  10  to  30 . The number of venues is not limited to three, and there may be a plurality of venues. The information provider/collector  40  and the distributor  50  are described by way of examples. For example, there may be a plurality of information providers/collectors and a plurality of distributors. Also, there may be an independent information provider and an independent information collector. 
   In the information collecting unit  11 , information to be provided such as advertisements of performances and information on merchandise and selling of related merchandise is stored beforehand in the provided information storage unit  112 . Alternatively, the provided information can be received by the transmitter/receiver  111  through the network  70  and can be stored in the provided information storage unit  112 . From among the stored provided information, necessary information is transmitted through the network  15  in the venue  10  to the audience terminals  12  to  14  situated in seats at predetermined time. 
   For example, the audience terminal  12  is provided at an arm rest of each seat in the venue  10 . The personal information reading unit  123  is an IC-card reader or an IC card reader/writer. By inserting a storage medium such as an IC card of an audience member into the personal information reading unit  123 , stored personal information is read into the audience terminal  12 . Subsequently, various pieces of information transmitted from the information collecting unit  11  are received by the transmitter/receiver  121 , and the information is output by the provided information output unit  122  by displaying it on a screen or the like. 
   Concerning the output information, information on merchandise related to a performance is introduced prior to the start of the performance. During the performance, information such as the name of actors, or a diagram showing the relationships among characters is displayed in order to assist the audience member in understanding the performance. After the performance, a questionnaire form is displayed. If necessary, the audience member can input response information using the response information input unit  124 . The response information is transmitted to the information collecting unit  11 . For example, when a response to the questionnaire is input, the response information and information such as the age and occupation of the audience member read by the personal information reading unit  123  are transmitted to the information collecting unit  11 . If the audience member inputs “yes” in response to a question on the screen asking whether or not the audience member would like more information regarding the introduced merchandise or the like, inquiry information and personal information such as name, address, and telephone number read from the storage medium are transmitted to the information collecting unit  11 . The storage medium having stored therein the personal information may have an electronic money function of electronically storing currency value. If the audience member indicates, by inputting information to that effect, that the audience member would like to purchase displayed merchandise, a payment can be made at the same time. Also, the audience member can place an order for merchandise. 
   The response information input and transmitted by the audience terminals  12  to  14  are received by the information collecting unit  11  and are compiled by the compiler  113 . For example, responses to a questionnaire, the age and occupation of a respondent, inquiries for more information, and a list of orders for merchandise are compiled. The compiled results are utilized by the venue  10  which manages the information collecting unit  11 . The compiled results may be transmitted to the information provider/collector  40  and the distributor  50 . The information provider/collector  40  and the distributor  50  compile necessary information from among the information compiled at the venues  10  to  30  over the country and use the questionnaire results for building business strategy. Also, the information provider/collector  40  and the distributor  50  deliver merchandise to the audience&#39;s home by mail. Concerning inquiries for more information, the requested information can be sent by e-mail. 
   For the producer of a performance, it is possible to provide more information to each audience member using the audience terminals  12  to  14  installed at their seats. Since it is possible for each audience member to easily input information using the response information input unit  124  and the personal information reading unit  123 , it is possible to efficiently gather audience members&#39; responses to provided information automatically. Also, members of the audience can obtain plenty of beneficial information such as information about related merchandise, and information that assists members of the audience in understanding the content of a performance. At the same time, the members of the audience can easily request more detailed information. With an electronic money function, it is possible to place an order for related merchandise and make a payment. Thus, the audience members would no longer be required to queue for merchandise and to carry around purchased merchandise until they get home. It would become unnecessary for the merchandise distributor  50  to hire salesclerks at the venues  10  to  30  to sell merchandise. As a result, the sales productivity is increased. 
     FIG. 2  shows an example of the device configuration of the audience information collecting system  1 . In the following description, it is assumed that the venue  10  is a movie theater. 
   The information collecting unit  11  is a computer server apparatus including an interface  11   a , which includes a modem (modulator-demodulator) or a LAN adapter, for establishing a network connection; a control unit  11   b , which includes a processor, a read only memory (ROM), a random access memory (RAM), and the like, for performing various control processes; and a storage unit  11   c , which includes a hard disk or the like, for storing provided information and various processing programs. Each process performed by the information collecting unit  11  is performed by executing a processing program stored in the storage unit  11   c  or the like. 
   The audience terminal  12  includes an interface  12   a , which includes a LAN adapter or the like, for establishing a network connection; a control processor  12   b , which includes a processor, ROM, RAM, and the like, for performing various control processes; a reader/writer  12   c  for reading and writing an IC card which is inserted therein; a display  12   d  for displaying provided information; input keys  12   e  which audience members use for inputting information; and a storage unit  12   f , which includes a semiconductor RAM or the like, for temporarily storing provided information. In addition to these units, it is possible to provide an earphone terminal through which provided information is output, and earphones. The audience terminals  13  and  14  each have the same structure as that of the audience terminal  12 . The audience terminals  12  to  14  are installed at the corresponding seats in the venue  10  and are connected to the information collecting unit  11  by the LAN  15   a.    
     FIGS. 3A and 3B  show an example of the audience terminal  12 .  FIG. 3A  shows an example of the audience terminal  12  being installed at a seat, and  FIG. 3B  shows an external plan view of the audience terminal  12 . 
   In the venue  10 , as shown in  FIG. 3A , the audience terminal  12  is installed at a position such as an arm rest or a back rest of a seat  120  so that an audience member who sits in the seat  120  can see a display easily and can operate the audience terminal  12  easily. As shown in  FIG. 3B , on the upper surface of the audience terminal  12 , a card insertion slot  12   g  of the reader/writer  12   c  into which an IC card having stored therein personal information is inserted; the small size display  12   d , such as a liquid crystal display, for displaying provided information; and the input keys  12   e  for inputting information are provided. Instead of the input keys  12   e , a touch panel display, wherein information can be input by pressing the screen, can be used as the display  12   d . In this way, the display  12   d  also serves as an input unit. 
   An IC card is created beforehand at a reception desk of the venue  10  or at a predetermined store. When creating an IC card, personal information such as name, address, age, and e-mail address are stored in an IC memory in the IC card. In a registration process, a unique number of the IC card and a password for identifying the owner of the IC card are registered and are stored in the storage unit  11   c  of the information collecting unit  11  or in a server operated by a film distributor. Each audience member has his/her own IC card. The same IC card can be used at movie theaters all over the country. Once an IC card is created, the audience member is required to bring the IC card every time they go to movie theaters. When the audience member sits in a seat, the audience member inserts the IC card into the card insertion slot  12   g , and the audience terminal  12  reads personal information. The audience member is then provided with information via the display  12   d . Alternatively, when inputting response information to provided information using the input keys  12   e , the audience member inserts the IC card. Also, the IC card has an electronic money function wherein funds can be electrically transferred from a bank account. With the electronic money function, when the audience member wants to purchase merchandise displayed on the display  12   d , it is possible not only to place an order but also to make a payment using the audience terminal  12 . 
     FIG. 4  is a flowchart showing a process performed by the audience terminal  12  at a movie theater. 
   When an audience member sits in a predetermined seat, an IC card is inserted into the card insertion slot  12   g  of the audience terminal  12  (S 401 ). The control unit  12   b  performs processing to display a password input screen on the display  12   d . The password is used to authenticate the IC card and the owner of the IC card which will be used when the audience member answers a questionnaire and when personal information is read and transmitted from the IC card. The audience member inputs a password using the input keys  12   e , and the input password is sent to the information collecting unit  11 . The input password is checked against the legitimate password that was registered when the IC card was created. Alternatively, the input password can be sent from the information collecting unit  11  to a server operated by a motion picture company through a public telephone circuit  70   a , so that the server can perform authentication. If the input password does not match the registered password based on the authentication result (S 402 ), it is determined that the carrier of the IC card is not the legitimate owner of the IC card. Thus, the IC card is disabled and is ejected from the card insertion slot  12   g  (S 424 ). 
   If the input password matches the registered password, and the IC card is thus authenticated (S 402 ), the audience terminal  12  starts receiving provided information transmitted from the information collecting unit  11 . When the venue  10  is a movie theater, the audience terminal  12  receives information which introduces merchandise such as a pamphlet and a poster related to a movie until the start of the screening of the movie, and the received information is displayed on the display  12   d  (S 403 ). 
   While the screen which introduces merchandise is being displayed, the audience member can purchase displayed merchandise by operating the input keys  12   e . When information indicating that the audience member wants to purchase merchandise is input by operating the input keys  12   e  (S 404 ), the control unit  12   b  performs processing to transmit personal information such as the name and address of the purchaser, which is read from the IC card using the reader/writer  12   c , and purchase information including the name of the purchased merchandise is transmitted to the information collecting unit  11  (S 405 ). The information collecting unit  11  in turn sends password input screen information for making a payment, and the password input screen is thus displayed on the display  12   d . The password is used to make a payment using an electronic money function of the IC card. The password used here may differ from that used when authenticating the IC card at the time the IC card was inserted. The audience member inputs a password, and the input password is sent to the information collecting unit  11 . The information collecting unit  11  performs authentication. If the input password does not match the registered password (S 406 ), the purchase of the merchandise is cancelled, and the process returns to the merchandise introduction screen. If the input password matches the registered password (S 406 ), the audience terminal  12  receives information indicating that the authentication was successful from the information collecting unit  11 . The reader/writer  12   c  deducts the cost of the purchased merchandise from the amount of money stored in the IC card, thereby making a payment (S 407 ). If it is confirmed based on communication with the information collecting unit  11  that the money has been successfully deducted, the merchandise purchasing process is terminated. Then, the audience terminal  12  starts receiving merchandise information, and the related merchandise is continuously introduced in a similar manner until the start of the screening of the movie (S 403  to S 408 ). 
   When the movie is about to begin (S 408 ), commercials showing other movies and merchandise are screened prior to showing of a feature film. At the same time, the information collecting unit  11  sends information about movies and merchandise shown in the commercials. The audience terminal  12  receives the transmitted information and displays the information on the display  12   d  (S 409 ). If the audience member finds the content of the information interesting, the audience member can request more information by operating the input keys  12   e . When information indicating that the inquiry for information was made is input using the input keys  12   e  (S 410 ), the reader/writer  12   c  reads personal information such as the name, address, or e-mail address and sends the read information as inquiry information to the information collecting unit  11  (S 411 ). While commercials are being shown, the audience terminal  12  receives information concerning the content of the commercials, and the received information is displayed (S 409  to S 412 ). 
   When showing of the feature film begins (S 412 ), the audience terminal  12  receives information about the content of the movie from the information collecting unit  11  in association with the progress of the movie, and the received information is displayed on the display  12   d  (S 413 ). The information includes the name of the actors in the current scene, the setting, the name of the song being played, and the like. When the relationships among characters appearing on the movie are complicated, information such as a diagram showing the relationships among characters is also displayed in order to assist the audience member in understanding the movie. While the information about the content of the movie is being displayed, the audience member can store information displayed at a memorable scene by operating the input keys  12   e . After the movie ends, the stored information can be displayed again. When storing of information about the content of the movie is designated using the input keys  12   e  (S 414 ), the control unit  12   b  causes the storage unit  12   f  to store the received information (S 415 ). After the information is stored, the audience terminal  12  continues receiving information about the content of the movie until the movie ends (S 413  to S 416 ). 
   When screening of the movie is completed (S 416 ), and when information is stored in the storage unit  12   f  during the movie (S 417 ), the information is read from the storage unit  12   f  and is displayed on the display  12   d  (S 418 ). If no information is stored or if displaying of the information is completed, the information collecting unit  11  sends questionnaire information concerning the movie. The audience terminal  12  receives the questionnaire information (S 419 ), and the display  12   d  displays a screen asking the audience member whether the audience member would like to answer the questionnaire. If the audience member indicates that the audience member is willing to respond to the questionnaire by operating the input keys  12   e  (S 420 ), questions are displayed on the display  12   d  (S 421 ). Response information is input using the input keys  12   e  (S 422 ). When all the responses are input, the reader/writer  12   c  reads personal information such as the age and occupation of the audience member which is stored in the IC card. The personal information and the response information are transmitted to the information collecting unit  11  (S 423 ). Alternatively, the content of the transmitted personal information can be displayed when the audience member answers the questionnaire. Also, the content of the personal information can be designated by the audience member. When the questionnaire is completed, or when the audience member indicates that the audience member does not want to answer the questionnaire (S 420 ), the IC card is ejected from the card insertion slot  12   g  (S 424 ). The audience member exits from the venue  10  with the IC card. 
   In this manner, provision of the audience terminal  12  at each seat enables an information provider to directly provide each audience with more information compared with the conventional technology, thereby significantly increasing the information transmission efficiency. Since it becomes easy for the audience to input information with the assistance of the audience terminal  12 , the recovery rate of questionnaires is increased. The information collector can thus collect more information. Also, the audience can receive more information. With the IC card, personal information can be automatically input, or a payment can be automatically made. It thus becomes possible for the audience to easily request more information concerning interesting information or to readily purchase merchandise. 
     FIG. 5  is a flowchart showing a process performed by the information collecting unit  11  in the movie theater. 
   When members of the audience start entering the venue  10 , each audience member inserts their IC cards into the audience terminal  12  installed at each seat. The audience terminal  12  communicates with the information collecting unit  11  through the LAN  15   a  and authenticates the IC card and the audience member (S 501 ). Information indicating that the IC card was inserted into the audience terminal  12  is transmitted through the LAN  15   a . The information collecting unit  11  receives the information using the interface  11   a . The control unit  11   b  reads password input screen information from the storage unit  11   c  and transmits the information to the audience terminal  12 . The password input screen is displayed by the audience terminal  12 , and a password is input. The input password and an identification number unique to the IC card number are sent, and the information collecting unit  11  receives the password and the identification number. The control unit  11   b  performs processing to read a registered password which corresponds to the received identification number and to compare the input password against the registered password. The authentication result information is transmitted through the LAN  15   a . Authentication is performed every time an audience member enters the venue  10  and sits in a seat until the end of the showing of the movie. 
   The audience member is provided with information, and the information collecting unit  11  receives response information (S 502  to S 505 ) concurrently with authentication of the IC card. Information about merchandise related to the movie is directly input to the information collecting unit  11  by an input unit (not shown). Alternatively, such information is stored beforehand in the storage unit  11   c  from an information provider&#39;s server connected to the external public telephone circuit  70   a . When members of the audience start entering the venue  10 , merchandise information is sequentially read from the storage unit  11   c , and the merchandise information is transmitted to the audience terminals  12  to  14  from the interface  11   a  through the LAN  15   a  (S 502 ). 
   During transmission, when a purchase request for merchandise is input using the audience terminal  12 , the information collecting unit  11  receives purchase information including the name of the requested merchandise and personal information such as the name and address of a purchaser (S 503 ). In order to authenticate the IC card (S 504 ), the information collecting unit  11  reads password input screen information from the storage unit  11   c  and transmits the information to the audience terminal  12 . In a manner similar to that in authenticating the IC card when the IC card is inserted, the password input screen is displayed by the audience terminal  12 . A password is input, and the password and an identification number unique to the IC card number are transmitted. The information collecting unit  11  receives the input password and the identification number. The control unit  11   b  performs processing to read a registered password which corresponds to the received identification number and to compare the input password against the registered password. The authentication result information is transmitted through the LAN  15   a . If the IC card is authenticated, the audience terminal  12  deducts a predetermined amount of money from the currency value stored in the IC card. When the information collecting unit  11  determines that the payment has been correctly completed, the information collecting unit  11  stores the purchase information in the storage unit  11   c  (S 505 ). A similar purchasing procedure is repeated until the start of the screening of the film. 
   When it becomes time to start screening the film, commercials are displayed on the screen. The information collecting unit  11  sequentially reads information about movies or merchandise shown in the commercials from the storage unit  11   c  in accordance with the progress of images on the screen, and the information collecting unit  11  transmits the information to the audience terminals  12  to  14  (S 506 ). During transmission, when an inquiry for more information concerning the transmission content is input using the audience terminal  12 , inquiry information including the content of the inquiry and personal information such as the name, address, and e-mail address of the inquirer is transmitted. The information collecting unit  11  receives the inquiry information (S 507 ) and stores the information in the storage unit  11   c  (S 508 ). When screening of the feature film begins, the information collecting unit  11  sequentially reads information about actors in the movie and descriptions of the content from the storage unit  11   c  and transmits the read information to the audience terminals  12  to  14  in accordance with the progress of the movie (S 509 ). 
   When the movie ends, the information collecting unit  11  reads questionnaire information concerning the content of the movie and transmits the questionnaire information to the audience terminals  12  to  14 . When the information collecting unit  11  receives response information which includes the input responses (S 511 ), the information collecting unit  11  stores the response information in the storage unit  11   c  (S 512 ). When members of the audience exit from the venue  10 , and when reception of the response information is completed, the merchandise purchase information, the inquiry information, and the questionnaire response information stored in the storage unit  11   c  are compiled (S 513 ). Concerning the merchandise purchase information and the inquiry information, the number of items, purchaser, and personal information of the purchaser are compiled for each merchandise. Concerning the response information to questionnaires, the responses are compiled by age or occupation.
