Abstract
Description
Technical Field
[0001] The present invention relates to a negotiation system that enables video calls by a plurality of information terminals connected via a network, an image synchronous display method executed on an information terminal constituting the negotiation system, and a program executed by the information terminal.
Background Art
[0002] In recent years, contactless services have become established, and cases have increased where a provider of goods and a customer who receives the goods negotiate (WEB negotiation) via a network without actually facing each other, and purchase and contract decisions are made. Technologies related to this have also been proposed (see, for example, the following patent documents).
[0003] In conventional WEB negotiation, a method has been taken in which the camera of a mobile terminal such as a smartphone is used to project an actual product and the product is explained in a live distribution format. In such a case, however, the actual product must be at hand. For example, when explaining a rental property in a live distribution format, each time a negotiation is held, the organizer must actually visit the rental property and take a photograph with a mobile terminal, making it difficult to set a large number of negotiations.
[0004] Also, instead of the live distribution format, negotiations are sometimes carried out while displaying pre-prepared content images on the screen of an information terminal. However, if both the organizer side and the customer side of the negotiation cannot recognize which part of the product they are viewing, there is a risk of claims due to discrepancies in recognition and opportunity losses due to delays in the customer's decision-making.

Summary of the Invention
[0006] Against the backdrop of the above circumstances, the present invention aims to provide a business negotiation system, an image synchronization display method, and a program that enable each information terminal participating in a video call over a network to share content images with the same field of view and angle, thereby enhancing mutual understanding among participants. [Means for solving the problem]
[0007] The first stage of this invention's negotiation system is defined as follows: A business negotiation system that enables video calls between multiple information terminals connected via a network, The aforementioned information terminal is The display unit has a content image display area for displaying content images, A synchronization operation selection means detects the selection and deselection of an exclusive synchronization operation for the content image, and, when the synchronization operation is selected, transmits a synchronization start signal to other information terminals participating in the call. Operation data transmission means for transmitting operation data corresponding to display operations on the content image to the other information terminal, A synchronization start signal receiving means that receives the synchronization start signal from the other information terminal, A receiving processing means that, after receiving the synchronization start signal, performs a display operation on the content image based on data corresponding to the display operation transmitted from the other information terminal, Equipped with, The content images displayed in the content image display area of each information terminal participating in the aforementioned call are capable of synchronized display.
[0008] In this defined first-phase business negotiation system, synchronized content images can be displayed in the content image display area of each information terminal participating in the call. In other words, since the business negotiation can proceed while sharing content images with the same field of view and angle, mutual understanding among participants can be enhanced.
[0009] The second aspect of this invention is defined as follows: In the first phase, the specified business negotiation system is displayed on the video call screen of the information terminal at all times, and the synchronization operation selection means detects the selection and deselection of the synchronization operation when the synchronization icon is operated.
[0010] According to the second phase of the business negotiation system defined in this way, synchronized display can be achieved at any time the synchronization icon is operated, initiated by any information terminal participating in the call.
[0011] Here, the following operations can be performed synchronously: changing the display magnification of the content image displayed in the content image display area, moving the display portion within the same content image, switching to another content image, and overwriting the display of line drawings on the content image (third phase).
[0012] Furthermore, in a sales negotiation system, it is desirable to allow customers to view products from all angles, thereby making the products more concretely visible and creating a sense of immersion for the customer. Therefore, in this invention, the image displayed in the content image display area can be selected from a plurality of appearance images obtained when the shooting direction is rotated 360 degrees around the object being photographed, each with a different shooting direction. By performing a predetermined image switching operation, the system can be configured to switch and display the external image in a manner that rotates the object being photographed in one direction (fourth aspect).
[0013] Furthermore, the content image display area can display a portion of a panoramic image of the interior or interior of the object being photographed. The system can be configured so that the portion of the panoramic image displayed in the content image display area is moved based on a predetermined display portion movement operation (fifth aspect).
[0014] The sixth aspect of this invention, the image synchronization display method, is defined as follows: A method for synchronously displaying content images between an information terminal having a content image display area on its display unit and other information terminals connected via a network, The aforementioned information terminal, A synchronization operation selection step that detects the selection and deselection of an exclusive synchronization operation for the content image, and transmits a synchronization start signal to the other information terminal when the synchronization operation is selected, A step of transmitting operation data corresponding to a display operation on the content image to the other information terminal, A synchronization start signal reception step which receives the synchronization start signal from the other information terminal, After receiving the synchronization start signal, the receiving processing step includes executing a display operation on the content image based on operation data corresponding to the display operation transmitted from the other information terminal, Execute this. According to the image synchronization display method for the sixth position as defined in this way, the same effect as that for the first position is achieved.
[0015] The program of the seventh aspect of this invention is defined as follows: The display unit has a content image display area for displaying content images, and is connected to other information terminals via a network. A synchronization operation selection step that detects the selection and deselection of an exclusive synchronization operation for the content image, and transmits a synchronization start signal to the other information terminal when the synchronization operation is selected, An operation data transmission step of transmitting operation data corresponding to a display operation on the content image to the other information terminal, A synchronization start signal reception step of receiving a synchronization start signal from the other information terminal, After receiving the synchronization start signal, a reception corresponding processing step of executing a display operation on the content image based on the operation data corresponding to the display operation transmitted from the other information terminal, are to be executed. The program of the seventh aspect defined in this way corresponds to the image synchronization display method of the sixth aspect and has the same operations and effects.

[0017] Next, embodiments of the present invention will be described in detail with reference to the drawings. In Figure 1, 1 represents a business negotiation system used for conducting web-based business negotiations. The business negotiation system 1 in this embodiment comprises an information terminal 2 for the organizer, information terminals 4A and 4B for the guest (customer), a remote business negotiation server 6, a login server 7, an authentication server 8, and a content management server 9. These information terminals 2, 4A, and 4B and servers 6, 7, 8, and 9 are connected to a network 10, and video calls are made possible by these multiple information terminals 2, 4A, and 4B sending and receiving audio and image data via the network 10. Here, the number of information terminals on the guest's side participating in the business negotiation is not limited to two; it may be one or three or more. Furthermore, in addition to the internet, the network 10 can also utilize wired LAN (Local Area Network), wireless LAN, etc.
[0018] The organizer's information terminal 2 can be, for example, a smartphone, tablet, or personal computer. The following explanation will use the case where the organizer's information terminal 2 is a personal computer as an example. As shown in Figure 2, the information terminal 2 includes a CPU 11, ROM 12, RAM 13, storage device 14 such as a hard disk, a display 15, a network interface 16, a keyboard 17, a mouse 18 as a pointing device, a camera 19, a microphone 20, a speaker 21, a media interface 22, an external device interface 23, and a bus line 25. In the information terminal 2, the CPU 11 reads various programs and data stored in the ROM 12 and storage device 14, and when viewed as a whole, it functions as a communication unit 32, a display unit 34, an operation unit 36, a control unit 50, etc., as shown in Figure 3. Similarly, the control unit 50 also functions as various means.
[0019] The communication unit 32 includes a network interface 16 and communicates with other information terminals and servers.
[0020] The display unit 34 includes the display 15 and displays various information. For example, when a video call is started, the display unit 34 displays the video call screen 35, which serves as a business negotiation screen as shown in Figure 7. A detailed explanation of this video call screen 35 will be given later.
[0021] The operation unit 36 receives input such as various commands. If the information terminal 2 is a personal computer, the operation unit 36 is configured to include, for example, a keyboard 17 and a mouse 18. The keyboard 17 is an input means equipped with multiple keys for inputting characters, numbers, various instructions, etc. The mouse 18 is an input means for selecting and executing various instructions, selecting processing targets, moving the cursor, etc.
[0022] The imaging unit 38 includes a camera 19 and primarily captures images of terminal users (business negotiation participants). The captured data (video data) from the imaging unit 38 is transmitted to other information terminals 4A and 4B via the network 10.
[0023] The sound pickup unit 40 includes a microphone 20 and acquires audio data by picking up the voice of the terminal user, etc. The audio data is transmitted along with the above-mentioned captured data to other information terminals 4A and 4B via the network 10.
[0024] The audio output unit 42 includes a speaker 21 and outputs audio data sent from other information terminals through the speaker 21.
[0025] The storage unit 44 includes a storage device 14 such as a hard disk. However, it may also be composed of flash memory or ROM. Various programs are stored in the storage unit 44. For example, the OS (Operating System) and various applications are stored. The applications stored in the storage unit 44 include programs that perform the processes described later. The programs that perform the processes described later may be pre-installed in the storage unit 44, but when accessing the server to participate in a business negotiation, they may be sent from the server to the information terminal via the network 10 and installed in the storage unit 44 at that time. In this case, the programs may be stored in RAM 13.
[0026] The control unit 50 includes the following: image / sound processing means 51, image operation reception processing means 52, synchronization operation selection means 53, operation data transmission means 54, synchronization start signal reception means 55, and reception response processing means 56.
[0027] The image and audio processing means 51 receives and transmits captured data and audio data, and performs processing such as displaying the image on the display unit 34 and outputting the audio from the audio output unit 42.
[0028] The image manipulation receiving processing means 52 receives display operations such as changing the display magnification of the content image, as described later, creates and records corresponding operation data, and displays the content image at a predetermined field of view and angle.
[0029] The synchronization operation selection means 53 detects the user's selection and deselection of an exclusive synchronization operation on the content image and outputs a synchronization start signal to the other information terminals 4A and 4B. Specifically, when the synchronization icon 70 provided in the content image display area 63 (see Figure 7) is pressed in an asynchronous state, the selection of a synchronization operation is detected and a synchronization start signal is sent to the other information terminals 4A and 4B participating in the call. After the synchronization icon 70 is pressed, the content of the display operation on information terminal 2 is reflected on the screens of the other information terminals 4A and 4B, as will be described later, so that exclusive synchronization operation by information terminal 2 becomes possible. This exclusive synchronization operation is deactivated when the synchronization icon 70 on information terminal 2 is pressed again, and a desynchronization signal is sent to the other information terminals 4A and 4B participating in the call.
[0030] After the synchronization operation selection means 53 detects the selection of an exclusive synchronization operation, the operation data transmission means 54 transmits operation data corresponding to the display operation for the content image to the other information terminals 4A and 4B.
[0031] The synchronization start signal receiving means 55 accepts a synchronization start signal from another information terminal if the information terminal 2 itself is in an asynchronous state and a synchronization start signal is sent from either of the other information terminals 4A or 4B. Thereafter, display operations based on mouse operations on information terminal 2 are disabled.
[0032] The receiving processing means 56, after receiving a synchronization start signal from another information terminal (e.g., information terminal 4A) in the synchronization start signal receiving means 55, executes a display operation on the content image of information terminal 2 based on the operation data transmitted from the other information terminal (e.g., information terminal 4A).
[0033] The above describes the organizer's information terminal 2. However, the guest's information terminals 4A and 4B can also use terminal devices such as smartphones, tablet devices, or personal computers, similar to the organizer's information terminal 2. In this example, the guest's information terminals 4A and 4B are configured with the same personal computer as the organizer's information terminal 2. Components common to both terminals are indicated using the same symbols, and their explanations are omitted.
[0034] On the other hand, the remote negotiation server 6, login server 7, authentication server 8, and content management server 9 are built using general-purpose computers and are equipped with a CPU, ROM, RAM, storage devices such as hard disks, a display, network interface, keyboard, mouse as a pointing device, media interface, external device interface, and bus lines. These components have the same configuration as the CPU 11, ROM 12, RAM 13, storage device 14 such as a hard disk, display 15, network I / F 16, keyboard 17, pointing device 18, media I / F 22, external device I / F 23, and bus line 25 in the aforementioned information terminal 2, so their explanation will be omitted.
[0035] The remote business negotiation server 6 is a server device similar to a conference server in a well-known remote conferencing system, and it distributes images, audio, and other data received from each information terminal to other information terminals participating in the same meeting (business negotiation).
[0036] Login server 7 manages products for each domain (e.g., cars, motorcycles, real estate) and the number of content generated per user.
[0037] Authentication server 8 is responsible for user management, managing user company information and other data, and exchanging tokens with login server 7.
[0038] The content management server 9 primarily manages the generated content images. Furthermore, this server allows the organizer to log in to the business negotiation system 1 and schedule business negotiations. The storage unit of this content management server 9 stores content images related to products. Here, a vehicle can be used as an example of a product. In this case, as shown in Figure 4, the storage unit of the content management server 9 stores data associated with the vehicle's ID (e.g., C1), including a content image representing the vehicle's exterior (e.g., G1), a content image representing the vehicle's interior (e.g., N1), and, if necessary, a secondary image (e.g., S1).
[0039] Here, the content image representing the vehicle's exterior (e.g., G1) is composed of multiple exterior images taken from different angles, each captured while rotating the camera 360 degrees around the vehicle. The content image representing the vehicle's exterior (e.g., G1) can be obtained as follows. First, video recording begins when a front view image of the vehicle is obtained, and the camera moves around the vehicle at a roughly constant speed, capturing the vehicle's exterior in 360 degrees. Next, frame images (still images) are extracted from the obtained video data at roughly equal intervals. By arranging the 36 images G1-1 to G1-36 (see Figure 5) extracted in this way in the order they were taken, and associating and connecting adjacent images, a single content image G1 can be created, consisting of multiple exterior images taken from different directions, as shown in Figure 5. In the example in Figure 5, G1-1 is a front view of the vehicle, G1-10 is a left side view of the vehicle, G1-19 is a rear view of the vehicle, and G1-28 is a right side view of the vehicle. Here, the symbols 1 to 36 appended after G1 are image IDs that identify each image within the content image G1 representing the exterior.
[0040] On the other hand, the content image representing the vehicle's interior (e.g., N1) is a panoramic image with a 360-degree field of view horizontally. However, the panoramic image may have a field of view of less than 360 degrees (e.g., 180 degrees or more). When a panoramic image is virtually treated as a three-dimensional spherical shape, as shown in Figure 6, the portion (region) P displayed on the information terminal screen is identified by its central coordinates P1 and the display magnification. An example of a portion of a panoramic image being displayed in the information terminal's content image display area 63 is shown in Figure 11.
[0041] On the other hand, the secondary image (e.g., S1) is a content image that captures a specific part of the vehicle separately from the exterior and interior images mentioned above.
[0042] In the business negotiation system 1 configured as described above, based on application processing performed on the organizer's information terminal 2, an email containing URL information for the business negotiation is sent in advance to the information terminals 4A and 4B that are scheduled to participate. At the scheduled date and time, each information terminal 2, 4A, and 4B accesses the remote business negotiation server 6, establishing a session between each information terminal 2, 4A, and 4B and the remote business negotiation server 6, enabling video calls between each information terminal 2, 4A, and 4B.
[0043] Next, we will explain the video call screen 35 on the display unit 34 of each information terminal after the video call has started, using information terminal 2 as an example. In this embodiment, the video call screen 35 is displayed on the display unit 34 of the information terminal 2 based on display control by the control unit 50. As shown in Figure 7, the video call screen 35 has a participant display area 61 on the left side of the screen that displays the participant's captured image, a content image display area 63 in the center of the screen that displays the content image, and a shared memo area 66 and a detailed information display area 67 on the right side of the screen. A product list display area 64 and a related image list display area 65 are also provided at the bottom of the screen.
[0044] The participant display area 61 shows images taken by the organizer 61a and guest 61b and 61c, respectively, which were captured by the cameras of the information terminals.
[0045] The shared memo area 66 is a display area for shared memos where both the host and guests can input text. By clicking the icon to omit the illustration, a text file save dialog will appear, allowing the contents of the shared memo area 66 to be saved as a text file on the user's device.
[0046] The detailed information display area 67 is the area for displaying detailed product information. This detailed product information must be set and registered in advance by the organizer.
[0047] The product list display area 64 is an area that displays a list of vehicles selected by the organizer for this business negotiation from among the vehicles registered in the storage unit of the content management server 9, as thumbnails. In this example, thumbnails 64a, 64b, 64c, and 64d of vehicles C1, C2, C3, and C4 are displayed.
[0048] The related image list display area 65 displays a list of content images associated with the selected vehicle C1 (see Figure 4) as thumbnails 65a, 65b, and 65c when any vehicle (in this case, vehicle C1) is selected from the list of vehicles displayed in the product list display area 64. In this example, image G1 representing the exterior, image N1 representing the interior, and sub-image S1 are displayed as related images for vehicle C1.
[0049] The content image display area 63 displays the image selected from the content images listed in the related image list display area 65. For example, if the thumbnail 65a of image G1, which represents the exterior, is selected, then the content image display area 63 will display G1-1 (front view of vehicle C1), which is the first image of image G1 representing the exterior.
[0050] Figure 8 shows the content image display area 63 in isolation. As shown in the figure, the content image display area 63 is controlled to always display the synchronization icon 70 and the magnification change icon 71. The synchronization icon 70 is the icon used to select and deselect the synchronization operation. As will be described later, when the synchronization icon 70 is operated and the synchronization operation is selected, a paint icon 73 and other icons are newly added and displayed in the content image display area 63. Users of the information terminal can perform display operations on the content image displayed in the content image display area 63, such as changing the display magnification, moving the display area, switching the displayed image, and overwriting the line drawing, by pressing these icons or by performing predetermined mouse operations. The above explanation of the video call screen 35, including the content image display area 63, was given using information terminal 2 as an example, but the same applies to the other information terminals 4A and 4B.
[0051] The following provides a detailed explanation of how to display content images. As shown in Figure 8, the content image display area 63 is provided with two types of icons 71a and 71b as magnification change icons 71. Icon 71a on the right side of the figure is an icon for enlarging the image. When icon 71a is pressed, the operation is received by the image operation reception processing means 52, and the content image is enlarged according to the number of times it is pressed. The icon 71b on the left side of the diagram is an icon for displaying a reduced image. When icon 71b is pressed, the operation is received by the image manipulation reception processing means 52, and the content image is displayed in a reduced size according to the number of times it is pressed.
[0052] Furthermore, in this embodiment, when the content image is displayed in an enlarged state, the portion of the content image displayed in the content image display area 63 (display portion) can be moved. Specifically, as shown in Figure 9, when the mouse pointer 18a is placed over the content image in the content image display area 63 and dragged in any direction, the operation is received by the image manipulation reception processing means 52, and the portion displayed in the content image display area 63 moves according to the direction and distance of the drag. In this example of Figure 9, the enlarged headlight portion moves to the central part of the content image display area 63. Furthermore, as shown in Figure 11, even when displaying only a portion of a panoramic image of the vehicle's interior, the displayed portion can be moved based on the same display portion movement operation.
[0053] Furthermore, in this embodiment, the content image can be switched to display as a different image. Specifically, when the content image is not enlarged (i.e., displayed at the smallest magnification), as shown in Figure 10(A), if the mouse pointer 18a is placed over the content image in the content image display area 63 and dragged horizontally (to the left in the figure), the operation is received by the image operation reception processing means 52, and the appearance images displayed in the content image display area 63 are sequentially switched and displayed as G1-1 → G1-2 → G1-3. That is, as shown in Figures 10(A), (B), and (C), according to this embodiment, the appearance images can be switched and displayed in a manner that rotates the vehicle C1 in one direction (counterclockwise in this example) up to 360 degrees with a single mouse operation. Furthermore, by clicking on other thumbnails 65b and 65c displayed in the related image list display area 65, the image G1 representing the exterior can be switched to displaying the image N1 or sub-image S1 representing the interior.
[0054] Furthermore, in this embodiment, line drawings can be overlaid on the content image. When the terminal user presses the sync icon 70, a paint icon 73 appears in the content image display area 63, as shown in Figure 11. By pressing this paint icon 73, the user can overwrite the content image display area 63 with freehand line drawings as shown in 74a and 74b. After drawing lines, an undo icon 75 and an eraser icon 76 are added to the content image display area 63. Pressing the undo icon 75 cancels the line drawing 74b that was just performed. Pressing the eraser icon 76 erases all line drawings 74a and 74b at once.
[0055] Next, the synchronization operations that can be performed in the business negotiation system 1 of this embodiment will be described. In this embodiment, it is possible to switch between a mode in which the content images displayed in the content image display area 63 of each information terminal 2, 4A, 4B participating in the call are synchronized, and an asynchronous mode in which each information terminal can display content images of different types. Each information terminal 2, 4A, and 4B is equipped with a synchronization icon 70 that is pressed to select or deselect exclusive synchronization operations for content images. When the press of the synchronization icon 70 is detected on any of the information terminals, the content images displayed on the screens of all information terminals can be synchronized at the initiative of the terminal that pressed the icon.
[0056] Figure 12 is a flowchart showing the switching of display operation modes for content images. When video communication begins, each information terminal first selects asynchronous mode for displaying content images (step S001). Next, an information terminal (e.g., information terminal 2) determines whether or not there is a synchronization start signal from another information terminal (step S002). If a synchronization start signal from another information terminal (e.g., information terminal 4A) is detected, the information terminal (e.g., information terminal 2) stops accepting display operations based on its own mouse operations (such as changing the magnification of the displayed image or moving the displayed part) and switches to a synchronous follow mode, which accepts display operations from the other information terminal (e.g., information terminal 4A) that has the initiative (step S005). This synchronous follow mode can be switched back to asynchronous mode by detecting a synchronization desynchronization signal from the other information terminal (e.g., information terminal 4A).
[0057] On the other hand, if no synchronization start signal is detected from other information terminals in step S002, the process proceeds to step S003 to determine whether or not a synchronization-initiated signal is output when the synchronization icon 70 of the information terminal itself (for example, information terminal 2 itself) is pressed (step S003). If a synchronization-initiated signal is detected here, the process switches to a synchronization-initiated mode in which the information terminal itself (for example, information terminal 2 itself) takes the lead in displaying other information terminals in synchronization (step S006). This synchronization-initiated mode can be switched back to asynchronous mode by detecting a synchronization-initiated release signal from the information terminal itself, which is output when the synchronization icon 70 is pressed again. In this example, when switching between synchronization and asynchronous mode using a single synchronization icon 70, it is preferable to change the display mode of the synchronization icon 70 according to the state so that it is easy to identify whether synchronization or asynchronous mode is selected.
[0058] On the other hand, if no synchronization-driven signal is detected in step S003, the asynchronous mode is maintained, and each information terminal can display content images in different forms. Thus, in this embodiment, any of the information terminals 2, 4A, or 4B can take the lead in performing synchronized display (synchronized operation).
[0059] Figure 13 is a sequence diagram showing an example of the process when information terminal 2 is switched to synchronous-driven mode. In this example, on the information terminal 2, the content image display operation 1 is performed (step S101), and after the image 1 corresponding to the display operation 1 is displayed (step S103), the synchronization icon 70 on the information terminal 2 is pressed to switch to synchronization-driven mode (step S104).
[0060] After switching to synchronous-led mode, information terminal 2 transmits a synchronization start signal to the other information terminals 4A and 4B (step S105). Here, since transmission and reception between each information terminal are performed via the remote negotiation server 6, the synchronization start signal from information terminal 2 is actually transmitted to the remote negotiation server 6, and the remote negotiation server 6, upon receiving it, transmits it to the other information terminals 4A and 4B. Upon receiving this synchronization start signal, information terminal 4A switches to synchronous-driven mode (steps S106, S107). Similarly, information terminal 4B also switches to synchronous-driven mode (steps S108, S109).
[0061] Next, information terminal 2 transmits the operation data (operation data 1) created in step S102 to the other information terminals 4A and 4B (step S112). Upon receiving this operation data 1, information terminal 4A displays image 1 (steps S113, S114). Similarly, information terminal 4B also displays image 1 (steps S115, S116). As a result, the content images on each information terminal are displayed in sync.
[0062] The operation data transmitted to the other information terminals 4A and 4B here includes the content ID, image ID, coordinates (X, Y) and display magnification information for the content image to be displayed, as well as the display range (part) of the image. If the display operation is to overwrite a line drawing, the position information of the line drawing is also transmitted to the other information terminals 4A and 4B. The other information terminals 4A and 4B that receive the operation data can display the image 1 by obtaining image data from the content management server 9 as needed.
[0063] Subsequently, when display operation 2 is performed on information terminal 2 (step S120), and the content image displayed on information terminal 2 (step S122) changes to image 2, operation data (operation data 2) corresponding to the content of display operation 2 is transmitted to the other information terminals 4A and 4B (step S123). Upon receiving this operation data 2, information terminal 4A displays image 2 (steps S124, S125). Similarly, information terminal 4B also displays image 2 (steps S126, S127). As a result, the content images on each information terminal are displayed in sync again.
[0064] As described above, the business negotiation system 1 of this embodiment allows synchronized content images to be displayed in the content image display area 63 of each information terminal 2, 4A, and 4B participating in the call. In other words, since the business negotiation can proceed while sharing content images with the same field of view and angle, mutual understanding among participants can be enhanced.
[0065] In the business negotiation system 1 of this embodiment, the synchronization icon 70 is displayed at all times on the video call screen 35 of the information terminals 2, 4A, and 4B. The synchronization operation selection means 53 detects the selection and deselection of a synchronization operation when the synchronization icon 70 is operated. Therefore, according to the negotiation system 1, synchronized display can be achieved at any time the synchronization icon 70 is operated, initiated by any information terminal participating in the call.
[0066] In the business negotiation system 1 of this embodiment, the following operations can be performed synchronously: changing the display magnification of the content image displayed in the content image display area 63, moving the display portion within the same content image, switching to another content image, and overwriting the display of line drawings on the content image.
[0067] Furthermore, in the sales negotiation system 1 of this embodiment, the image displayed in the content image display area 63 can be selected from a plurality of exterior images G1-1 to G1-36, each taken with a different shooting direction, obtained when the shooting direction is rotated 360 degrees around the vehicle. By performing a predetermined image switching operation, the exterior images G1-1 to G1-36 are switched and displayed in a manner that the vehicle rotates in one direction. This allows the exterior of the vehicle to be viewed from all directions, making the vehicle more concretely visible and creating a sense of immersion for the customer.
[0068] Furthermore, in the sales negotiation system 1 of this embodiment, a portion of a panoramic image of the vehicle's interior can be displayed in the content image display area 63, and the portion of the panoramic image displayed in the content image display area 63 is moved based on a predetermined display portion movement operation. As a result, the vehicle's interior can be viewed from all directions, making the vehicle more concretely visible and creating a sense of immersion for the customer.
[0069] Although embodiments of the present invention have been described in detail above, these are merely examples. The present invention can be configured in various modified forms without departing from its spirit. (1) For example, in the above embodiment, a personal computer was used as the information terminal, but it is also possible to use a smartphone or tablet terminal. In this case, the display operation of the content image can be performed by tapping, dragging, etc. with a fingertip on the touch pad provided on the display unit. Furthermore, even if smartphones and personal computers are used as information terminals and the display size of the content image display area is different, by making the aspect ratio of the content image display area the same on each of these terminals, it is possible to share content images with the same field of view and angle.
[0070] (2) It is also possible to perform synchronization operations other than those exemplified in the above embodiments. For example, as shown in Figure 14, an icon 80 associated with additional information is placed at a specific position in the content image, and when the icon 80 is pressed on the information terminal with control, a separate window of the additional information associated with the icon 80 is displayed on each information terminal.
[0071] (3) Product-related content images are not limited to still images; if necessary, product-related videos can also be displayed in the content image display area 63. For example, the 36 still images shown in Figure 5 can be linked together in the order they were taken to create a single video representing the exterior of the vehicle.
[0072] (4) Furthermore, although the business negotiation system in the above embodiment used cars as the subject of the content images, it can also be applied to products other than cars (for example, motorcycles, bicycles, watches, jewelry, real estate such as condominiums or rental apartments, or commercial facilities). In addition, when providing a service, it is also possible to use the venue where the service is provided (for example, a wedding venue) as the subject of the content images.
[0073] (5) The business negotiation system of the above embodiment can also be enhanced with a function to assist in the application for preliminary loan approval. Figure 15 is an explanatory diagram showing one such example. In this example, as shown in Figure 15(A), an icon 80 for loan pre-approval application is provided on the video call screen 35 of the organizer's information terminal 2. When the icon 80 is pressed, an information input screen 81 is displayed separately (see Figure 15(B)). The information input screen 81 can automatically reflect the information necessary for loan pre-approval application, such as dealer information registered in the database beforehand and information about the vehicle displayed in the content image display area 63. This information can also be entered manually as needed. After confirming that the necessary information has been entered in the information input screen 81, pressing the send icon 82 provided in the information input screen 81 will open a preliminary screening input screen owned by the credit company in a new tab on the customer's information terminal (e.g., 4A), and the information previously entered by the organizer will be transmitted when this new tab opens. By incorporating such features into the sales negotiation system, the efficiency and convenience of procedures when using loans for product purchases can be improved. [Explanation of Symbols]
