Description

  The present invention relates to a public personal computer terminal that can be used for an unspecified public in a public place such as an airport, a station, or a hotel lobby.

  With the spread of Internet technology, an Internet terminal that can be easily used by an unspecified public in a public place has been proposed.

  When a user tries to use an Internet service, a conventional Internet terminal allows an advertisement content prepared on a management server to be browsed in advance, and allows access to a desired website only after the browsing is completed. (For example, Patent Document 1). In addition, an Internet terminal that can use an Internet service on the condition that a coin amount of a necessary amount is inserted by attaching a coin counter to the Internet terminal has been put into practical use (Patent Document 2).

JP 2008-60930 A JP 2004-213585 A

  In the former case of the prior art, since the Internet terminal can provide the Internet service desired by the user only after the browsing of the advertisement content designated in advance is completed, the service is quickly started. There was no problem. In the latter case, since coins are assumed to be inserted, there is an unavoidable problem that user incentives are hindered and usage efficiency tends to be reduced. In addition, since none of these conventional technologies can provide software services other than Internet services, there is a problem that it is difficult to improve the utilization efficiency of the entire facility.

  Therefore, in view of the problems of the prior art, the object of the present invention is to preliminarily browse designated advertisement content and insert coins by incorporating a display control unit in addition to the Internet usage unit and application usage unit. Another object is to provide a public personal computer terminal that can immediately use various application software in addition to the Internet service for free, and can expect a great improvement in usage efficiency.

  The configuration of the present invention for achieving such an object includes a management control unit that downloads advertising content from a management server via the Internet, an Internet usage unit that downloads Internet information from an arbitrary web server by a user operation, On the display screen according to the operating time of the application usage unit that uses application software by the user's operation, the advertisement display unit that displays the advertising content from the management server on the display screen by the user's operation And a display control unit that controls the area ratio of the advertising area to the main area, and the management control unit selects and operates the Internet usage unit, the application usage unit, and the advertising display unit by user operation. Is the gist.

  The display control unit can expand the advertising region by reducing the main region on the display screen every time the operation of the application using unit passes a certain time.

  In addition, when the advertisement banner on the display screen is designated by the user, the display control unit may display the advertisement content corresponding to the designated advertisement banner on the display screen for a certain period of time. If only the display is made, the main area on the display screen may be restored.

  In addition, the display control unit can control the area ratio of the advertising area to the main area on the display screen according to the operating time of the Internet usage unit, and the management control unit is in a waiting time waiting for the user's input operation The advertising content of a specific advertiser can be displayed as a portal screen.

  According to such a configuration of the invention, the management control unit automatically starts, for example, simultaneously with power-on, and downloads and stores the latest advertising content from the management server. The advertising content here is content information for each advertiser to be displayed in the advertisement display unit, and includes not only product advertisements and product information, but also company information, job information, purchasing information, and the like. Alternatively, one or both of a moving image and a still image may be included. Further, the management control unit can select and operate any one of the Internet usage unit, the application usage unit, and the advertisement display unit by the user's operation, and can respond to the user's request. However, since the advertiser who provides the advertising content can obtain an advertising effect by allowing the user to browse the advertising content, it bears a consideration (advertisement fee) for the advertising effect. Therefore, the user can immediately use the personal computer terminal free of charge, and can expect improvement in utilization efficiency.

  The Internet using unit can access any web server via the Internet and download and use any Internet information by user operation. In addition, the application using unit can operate and use arbitrary application software such as Microsoft Word, Excel, Power Point, and the like by user operation. However, the processing target data of such application software is input by the user himself / herself through an input device such as a keyboard or an auxiliary memory such as a USB memory, a CD, or a DVD. It is assumed that the user himself / herself takes it out by printing out the apparatus or outputting it to an auxiliary memory such as a USB memory, a CD, or a DVD. Therefore, the user can receive any software service other than the Internet service via the application utilization unit, and can further improve the utilization efficiency.

  The display control unit changes and controls the area ratio of the advertisement area to the main area on the display screen in accordance with the operating time of the Internet usage unit or the application usage unit. However, the main area here is a display area of display information by the Internet using section or application using section that is in operation, and the advertising area is a display area other than the main area on the display screen. This is a display area for one or more advertisement banners linked to the advertisement content. The advertisement content from the management server includes link information between them in addition to the advertisement banner and advertisement content for each advertiser.

  For example, the display control unit reduces the main area on the display screen and expands the advertising area every time a certain period of operation of the Internet using part or the application using part is performed, thereby allowing the user to It is possible to force browsing and realize the advertising effect reliably. However, the main area and the advertisement area on the display screen can be divided into arbitrary forms. For example, the advertisement area is arranged in a band shape on a part or all of the four peripheral edges of the display screen, and the remaining area is set as the main area. As the operating time of the Internet using unit or application using unit elapses, the main region can be reduced to expand the advertising region, and the area ratio of the advertising region to the main region can be increased.

  When a specific advertising banner displayed in the advertising area of the display screen is specified by the user, the display control unit displays the advertising content linked to the advertising banner in the entire area of the display screen for a certain period of time. , The user can be forced to view. In addition, when the display control unit forcibly browses the advertising content in this way, the main area on the display screen is restored to the initial value, and the display information from the Internet usage unit or application usage unit again interferes with the main area. Display without.

  The management control unit can upload operation result data to the management server. However, the operation result data includes, for example, result data such as the use time of the personal computer terminal by the user, the operation time of the Internet use unit, the application use unit, and the advertisement display unit, and the browsing time of the advertisement content for each advertiser. It is assumed that the management server can analyze the operation result data and use it for the subsequent operation of the personal computer terminal.

  The management control unit displays the advertising content of a specific advertiser as a portal screen repeatedly during the standby time, so that the display screen can be used effectively as an advertising medium even during the standby time when there is no user. Can do. However, the specific advertiser mentioned here refers to one or more predetermined advertisers.

The interface box 15 incorporates a USB terminal, a CD drive, a DVD drive, etc., and inputs data from an auxiliary memory such as a USB memory, CD, DVD, etc. to the computer main body 11, and sends data from the computer main body 11 to a USB memory, The data can be output to an auxiliary memory such as a CD or DVD.

  The terminal 10 can be installed in any public place by being incorporated in a stand 22 with a chair 21 on which a user MA can sit (FIG. 2). An oblique storage panel 22a for the display device 12 is formed on the upper portion of the stand 22, and a small console 22b for placing a keyboard or the like is attached below the storage panel 22a. On the back side of the stand 22, a storage bracket fixing bracket 22 c (not shown) that stores the computer main body 11, the printer device 13, the interface box 15, and the like is formed. The chair 21 and the stand 22 are erected on a common base 23.

  1 and 2, the user MA can access the display device 12 and the input device 14, but the computer main body 11 is physically hidden so that the user MA cannot access it. And The printer device 13 can be accessed only by the user MA with respect to the printed document output section, and the interface box 15 is equipped with auxiliary memories such as a USB memory, a CD, and a DVD brought by the user MA. The user MA can access only the part.

  The computer main body 11 includes an operating system 31 and a software management control unit 32, an Internet use unit 33, an application use unit 34, an advertisement display unit 35, and a display control unit 36 (FIG. 3). The management control unit 32 can access the management server S on the Internet N via a browser, and the Internet usage unit 33 can access any web server on the Internet N via a browser. The application use unit 34 can operate and use any application software preinstalled in the computer main body 11, and the advertisement display unit 35 can display the advertisement content downloaded from the management server S on the display device 12. It can be displayed on the display screen. The display control unit 36 controls the area ratio of the advertisement area to the main area on the display screen according to the operating time of either the Internet utilization unit 33 or the application utilization unit 34.

  The operation of the management control unit 32 is, for example, as shown in the program flowchart of FIG.

  The program is started when the terminal 10 is turned on. First, the program accesses the management server S and inquires about the update information of the advertisement content held by the management server S (program step (1) in FIG. (Write as (1)). Therefore, if there is a correct response from the management server S (2), the update information is downloaded and fetched (3), and the operation result data of the terminal 10 at the previous operation (previous day) is uploaded to the management server S ( 4).

  Subsequently, the program deletes the operation history of the user MA during the previous operation remaining in the terminal 10 (5). Thereafter, the program displays the portal screen of FIG. 5 over the entire display screen of the display device 12 (6), and waits for an input operation by the user MA ((7), (6), (7)). . Therefore, if the user MA touches the touch panel on the portal screen, presses any key on the keyboard, or clicks the mouse (7), the program displays the menu screen of FIG. Display on the screen (8).

  Note that the portal screen in FIG. 5 repeatedly displays the advertising content of one or more specific advertisers displayed during the waiting time repeatedly in a large area of the display screen, and guides the input operation. Is displayed in the lower part. On the other hand, in the menu screen of FIG. 6, category selection buttons P1, P1,... For browsing advertisement contents by the advertisement display unit 35 are arranged in the most area of the display screen, and the functions are selected in the vertical column at the right end. Buttons P2, P2,... Are arranged. However, the function selection buttons P2, P2,... Are not directly related to the present invention except for the selection of the uppermost Internet usage section 33 and the selection of the next-stage application usage section 34, and thus the description thereof is omitted. .

  Thereafter, the program waits for any of the category selection buttons P1, P1,..., Function selection buttons P2, P2,... To be selected on the menu screen of FIG. , (9)) When the selection operation is not performed within a predetermined time, the process returns to the portal screen display step ((9), (10), (6), (7), (6)).

  When the selection operation is performed within a predetermined time (9), in the case of the “Internet” function selection button P2 for selection of the Internet usage unit 33 (11), the Internet usage unit 33 is activated (12). ) In the case of the “PC software” function selection button P2 for selecting the application using unit 34 (13), the application using unit 34 is activated (14), and in the case of any of the category selecting buttons P1, P1,. ((11), (13)), the advertisement display unit 35 is activated (15). The subsequent program transfers control to any of the Internet usage unit 33, application usage unit 34, and advertisement display unit 35 activated in program steps (12), (14), and (15). The operation history of the user MA is deleted (5), the original portal screen is displayed, and the next user MA is waited for an input operation ((6), (7), (6)).

  The operation of the Internet utilization unit 33 is, for example, as shown in the program flowchart of FIG.

  When the program is started through the program step (12) in FIG. 4 by pressing the “Internet” function selection button P2 for selection on the Internet utilization section 33 on the menu screen in FIG. 8 having the operation panel C is displayed as the display screen (program step (1) in FIG. 7, hereinafter simply referred to as (1)). However, the display screen of FIG. 8 includes an operation panel C, a main area M for browsers, and an advertisement area B for advertisement banners B1, B1,... Buttons C1, C1,..., URL display column C2 of the website being accessed, search word input column C3 at the time of search, and the like are included. When the "QR code" operation button C1 in the operation panel C is pressed, the URL displayed in the URL display field C2 is converted into a two-dimensional barcode QR code (registered trademark, the same applies hereinafter), and the main area M Can be easily read via the camera function of a mobile phone, for example.

  However, the operation of the function selection button P2 and the operation button C1 by the user MA may be any one of pressing, clicking, and touching regardless of the expression.

  Subsequently, the program stores the current time as the Internet use start time (2). If the subsequent operation of the user MA is a search (3), the program executes a search operation of Internet information on the Internet N (4) and an advertising banner B1 in the advertising area B of the display screen of FIG. , B1... Are changed to those of the advertiser that matches the search word at the time of search (5), and the web page information of the search result is displayed in the main area M of the display screen (7). When the operation of the user MA is not search (3), the web page information corresponding to the URL designated by the user MA directly entering the URL display field C2 is displayed in the main area M of the display screen (( 6), (7)).

  Thereafter, when a certain period of time has passed without any operation by the user MA ((8), (9)), the program closes the browser display screen (10) and controls the program steps of FIG. Returning to (12), (5) to (7), the display screen is the portal screen of FIG. Further, as long as the operation buttons C1, C1,... For the Internet in the operation panel C are properly operated ((8), (11), (12), (8)), the program can be used on the Internet N according to the operation. The predetermined Internet information can be downloaded and displayed in the main area M of the display screen. However, when the “END” operation button C1 on the operation panel C is operated, the program jumps to the program step (10) to terminate the use of the Internet. The Internet information from the web server can be printed out by the printer device 13 at any time, and output to and stored in the auxiliary memory attached to the interface box 15.

  Therefore, when Internet information is used as described above ((8), (11), (12), (8)), when a certain time has passed (12), the program is displayed in the main area of the display screen. M is reduced and the advertising area B is expanded ((13), FIG. 9). Incidentally, the display screen of FIG. 9 is larger than the display screen of FIG. 8 in that the advertising area B is enlarged by an amount corresponding to the advertising banners B1, B1,. Only the main area M is reduced. Further, when a certain time elapses (12), the program further reduces the main area M of the display screen and expands the advertisement area B ((13), FIG. 10). In the display screen of FIG. 10, the advertising area B is enlarged by an amount equivalent to the advertising banners B1 and B1 of the upper center part of the code H and I, and the main area M is reduced accordingly. Yes. However, in FIG. 8 to FIG. 10, the number of the advertising banners B1, B1,... In the advertising area B may be fixedly displayed. It may be displayed while scrolling.

  In this way, when the use of the Internet information is continued ((8), (11), (12), (8)), the main area M of the display screen is reduced in a stepwise manner for every predetermined time. When the advertising area B is enlarged step by step ((12), (13)), the user MA presses or clicks, touches, or touches an arbitrary advertising banner B1 in the advertising area B on the display screen. (14), the advertisement content linked to the advertisement banner B1 is popped up and displayed on the display screen ((15), FIG. 11), and the advertisement content can be browsed. In the display screen of FIG. 11, in the vertical column on the right end, in order from the top, a display D1 of the category to which the advertising content belongs, an operation button D2 for making a telephone call to a contact person of the advertising content, A QR code display D3 indicating contact information, an upper and lower operation buttons D4 for browsing other pages of the advertisement content, and an operation button D5 for returning to the original screen are arranged.

  The program displays the advertising content of FIG. 11 (15), waits for a certain period of time (16), updates the use start time previously stored in the program step (2) (17), and displays The main area M and the advertisement area B on the screen are restored to the original initial values in FIG. 8, and the use of the Internet information is further continued ((17), (8)). That is, when the program forces the user MA to browse the advertisement content in FIG. 11 for a certain time (16), the program can restore the main area M of the display screen on the condition (17).

  Next, the application utilization part 34 is as the program flowchart of FIG. 12, for example.

  When the program is started via the program step (14) of FIG. 4 by pressing the function selection button P2 of “PC software” for selection on the application utilization unit 34 on the menu screen of FIG. 13 is displayed in order to select any of the application software built in the computer (program step (1) in FIG. 12, hereinafter simply referred to as (1)). ).

  However, the display screen of FIG. 13 includes, in addition to the operation panel C, a main area M for guide messages and an advertisement area B for advertisement banners B1, B1,... In addition to the buttons C4, C4..., Various operation buttons C5, C5. Therefore, when, for example, the “word” selection button C4 in the operation panel C is pressed, the Word program is activated (2) and the display screen shown in FIG. In the main area M of the display screen of FIG. 14, the Word program screen is opened, and the selection buttons C4, C4,... The button is changed to C5, and the others are disabled.

  Subsequently, the program stores the current time as the start time for using the application software (3). Further, when the data file to be processed by the application software opened in the main area M is designated through the operation button C5 of the “file operation” by the operation of the user MA thereafter (4), The data file is opened and displayed in the main area M (5). The data file at this time may be a ready-made file in an auxiliary memory such as a USB memory, a CD, or a DVD attached to the interface box 15 by the user MA. It may be a file of input data.

  After that, when a certain period of time has passed without any operation by the user MA ((8), (9)), the program stops the application software as it is (10), and controls the program step of FIG. Returning to (14), (5) to (7), the display screen is the portal screen of FIG. As long as the program operates the application software displayed in the main area M properly ((8), (11), (12), (8)), the program operates the application software according to the operation, Data of a specified data file can be processed appropriately and sequentially. However, when the “End Word” operation button C5 on the operation panel C is pressed, it is possible to jump to the program step (10) and terminate the use of the application software.

  When the use of the application software is artificially terminated through the “end word” operation button C5 in this way, the program designates the auxiliary memory that is attached to the interface box 15 with the processed data. It is assumed that the user MA is instructed to execute one or both of outputting to a file and storing it, or causing the printer device 13 to print out. Therefore, the user MA can remove the auxiliary memory storing the processed data file from the interface box 15 and take it home, and can bring back the print result of the processed data.

  When application software is used as described above ((8), (11), (12), (8)), when a certain time has elapsed (12), the program is displayed in the main area M of the display screen. Is reduced to expand the advertising area B ((13), FIG. 15). The display screen of FIG. 15 is larger than the display screen of FIG. 14 in that the advertising area B is enlarged corresponding to the advertising banners B1, B1,. Region M is reduced. Further, when a certain time has passed (12), the program further reduces the main area M of the display screen and expands the advertising area B (13). However, the display screen at this time is the same as that in FIG. 10, and the advertising area B is enlarged by the amount corresponding to the advertising banners B1 and B1 at the center of the upper stage, and the main area M is reduced accordingly. .

  In this way, when the application software continues to be used ((8), (11), (12), (8)), the main area M of the display screen is reduced gradually in a certain time. When the advertisement area B is expanded in stages ((12), (13)), the user MA designates an arbitrary advertisement banner B1 in the advertisement area B on the display screen (14), The advertisement content linked to the advertisement banner B1 is popped up and displayed on the display screen ((15), FIG. 11) and can be browsed.

  Further, after displaying the advertising content of FIG. 11 (15), the program waits for a certain period of time (16), and updates the use start time previously stored in the program step (3) (17). Then, the main area M and the advertisement area B on the display screen are restored to the original initial values in FIG. 14, and the use of the application software is further continued ((17), (8)). That is, when the program forces the user MA to browse the advertisement content in FIG. 11 for a certain time (16), the program can restore the main area M of the display screen on the condition (17).

  Next, the operation of the advertisement display unit 35 is, for example, as shown in the program flowchart of FIG.

  When the program is started through the program step (15) in FIG. 4 by pressing any of the category selection buttons P1, P1,... For browsing advertisement contents on the menu screen in FIG. All advertisement banners B1, B1,... Belonging to the large category (category) corresponding to the category selection button P1 are arranged and displayed on the display screen (program step (1) in FIG. 16, hereinafter, simply as (1)). (FIGS. 17 and 18).

  However, FIG. 17 corresponds to the “job selection” category selection button P1 in FIG. 6, and FIG. 18 corresponds to the “business / consultation” category selection button P1. In the display screens of FIGS. 17 and 18, function selection buttons P2, P2,... Similar to those on the right end of FIG. 6 are arranged in a vertical line on the right end, and advertisement banners B1, B1. Up and down operations for scrolling and displaying the large classification (category) display D1, the small classification selection buttons D6, D6..., And the advertising banners B1, B1. Button D4 and operation button D5 for returning to the original screen are arranged in a vertical line. Therefore, on the display screen of FIG. 17 or 18, when one of the small category selection buttons D6, D6... Is pressed to select a small category (2), the program will display the advertising banners B1, B1 belonging to the selected small category. ... Are extracted and displayed (FIG. 19). However, FIG. 19 corresponds to the case where the “law office” selection button D6 is pressed on the display screen of FIG.

  In FIG. 19, when an arbitrary advertisement banner B1 is designated and a designated advertisement is selected (3), the program displays the advertisement content of the designated advertisement corresponding to the designated advertisement banner B1 on the display screen (( 4), FIG. 11). However, in order to display the advertisement content of FIG. 11, not only the advertisement banner B1 on the display screen of FIG. 19 but also the advertisement banner B1 on the display screen of FIGS. 17 and 18 may be designated. And

  Thereafter, the program appropriately applies the advertising banners B1, B1,... On the display screens of FIGS. 17 to 19, selection buttons D6, D6..., Operation buttons D4, D5, operation buttons D4, D5, etc. on the display screen of FIG. As long as the operation is performed, arbitrary advertisement contents can be selected and displayed in order and can be viewed by the user MA ((5), (8), (11), (5)). On the other hand, if such a display operation is not performed (5), the timer count for inoperable time measurement is started (6), and when a certain time elapses (7), control is performed in the program step (15) of FIG. , (5) to (7), the display screen is the portal screen of FIG. When the operation button D2 for making a call on the display screen of FIG. 11 is operated ((5), (8)), the program makes a call to the contact of the advertisement content being displayed (9). The necessary calls can be made (10).

  17 to 19, function selection buttons P2, P2,... Are arranged in a vertical line at the right end as in the menu screen of FIG. Therefore, when the "Internet" or "PC software" function selection button P2 is pressed on the display screens of FIGS. 17 to 19, the program of FIG. 16 is interrupted at that point, and the program step (12) or program of FIG. Assume that control is transferred to step (14). Further, the display screen of FIG. 11 displayed through the program steps (4) and (11) of FIG. 16 has function selection buttons P2, P2,... Similar to those of FIGS. You may change to 20 display screens.

  In the above description, the program steps (11) to (17) of FIG. 7 reduce the main area M on the display screen according to the Internet usage time, that is, the operating time of the Internet usage unit 33, and the advertising area B As a result, the change control is performed to increase the area ratio of the advertisement area B to the main area M, and the advertisement content corresponding to the advertisement banner B1 designated by the user MA is forcibly browsed for a certain period of time. I am letting. Further, the program steps (11) to (17) in FIG. 12 operate in exactly the same manner depending on the usage time of the application software, that is, the operating time of the application using unit 34. Therefore, each of the program steps (11) to (17) in FIG. 7 and FIG. 12 can be configured as a common subprogram used by the Internet utilization unit 33 and the application utilization unit 34, respectively, and the display control in FIG. It is assumed that the unit 36 corresponds to this subprogram.

  The control mode of the main area M and the advertising area B on the display screen by the display control unit 36 is such that the main area M and the advertising area B are sequentially changed as shown in FIGS. May be adopted. For example, a strip-shaped advertisement area B is arranged below the main area M (FIG. 21), and the strip-shaped advertisement area B to be added above the main area M as the operating time of the Internet utilization section 33 or the application utilization section 34 elapses. The width may be gradually expanded downward (arrow direction in the figure). Further, the width of the L-shaped advertisement area B along the left side and the lower side of the main area M may be sequentially increased rightward and upward (FIGS. 22A and 22B). Further, an advertisement area B that moves irregularly in the main area M may be arranged (FIG. 23A), and the area of the advertisement area B may be sequentially enlarged (FIG. 23B). Note that the advertisement area B may be expanded stepwise as time elapses, or may be expanded continuously.

  According to the present invention, in addition to the Internet service, services for using various application software can be immediately provided to the public free of charge, and can be appropriately operated by being placed in any public place.
