[0036] [Information sharing system]

Next, an information sharing system including a plurality of navigation devices 1 will be described. Figure 2 shows a configuration example of the information sharing system. In FIG. 2, the information sharing system 100 includes a plurality of navigation devices la˜: Lc. Each navigation device la˜: Lc has the configuration shown in FIG. That is, each navigation device la to l c communicates with the server 101 or another navigation device 1 using the communication device 38.

[0037] Basically, each navigation device la ~: Lc can send and receive information by connecting to the server 101. For example, when user A who operates navigation device la provides certain information to other users B and C, user A uploads the information to server 101, and users B and C transmit the information to server 101. Download to each navigation device lb and lc. In addition, each navigation device la˜: When Lc is configured to be able to communicate with peer “to peer” (hereinafter referred to as “P2P”), as shown by a broken line 107 in FIG. C can send and receive information directly without going through server 101 It is.

[0038] Each user A to C can share information by logging in to the communication network that constitutes the information sharing system 100 by operating each navigation device la ~: Lc and becoming a member of the information sharing system 100 Become. Specifically, each user inputs a predetermined user name, password, and the like on the navigation device 1 and logs in to the communication network. The logged-in navigation device 1 recognizes other navigation devices 1 that have already logged in on the communication network, and is recognized by other navigation devices 1. Thus, the user becomes a member of the information sharing system 100 until the communication network power is also logged out. In addition, as a basic function, the navigation device 1 constituting the information sharing system (that is, logged in) periodically obtains the current position information of its own vehicle from other members' navigation devices 1. Send to. As a result, while participating in the information sharing system, each member can mutually recognize the current position of the other member's vehicle.

[0039] [Information transmission / reception method]

Next, a basic information transmission / reception method in the information sharing system 100 will be described. In this embodiment, each navigation apparatus 1 transmits and receives music data reproduced by the audio output unit 50 to each other in the information sharing system 100. That is, the music data is an example of provided information in the present invention.

[0040] Hereinafter, a method for transmitting and receiving music data will be described in detail. In FIG. 2, user A who uses navigation device la is an information provider (i.e., information sender), and user B and user C who use navigation devices lb and lc are information receivers. Assume that music data is transmitted and received.

[0041] The navigation device la of the user A who is an information provider includes a music DB 110 that stores a large number of music data. The navigation apparatus la includes a music list 120 that is a list of a large number of music data stored in the music DB 110. The music DB 110 and the music list 120 can be stored in the data storage unit 36 shown in FIG.

[0042] Fig. 3 shows a basic flow of a music data providing method. In this example, user B Suppose that user A requests a music list and music, and user A provides music data to all users including user B.

[0043] First, the user B operates his / her navigation device lb to request the music list 120 from the user A who is the information provider (step Sl). On the other hand, the navigation device 1a of the user A transmits the music list 120 to the navigation devices 1 of all members of the information sharing system 100 (step S2).

[0044] Each user who receives the music list 120 selects the music to be reproduced with reference to the music list, and sends a request for transmission of the music (also referred to as "request") to the user A navigation device. Send to la (step S3). In response to this, the navigation device la of the user A transmits the music data of the requested music to the navigation devices 1 of all the members participating in the information sharing system 100 (step S4). In this way, members participating in the information sharing system 100 can share the music data stored in the navigation device 1 of the user A.

FIG. 4 shows a flowchart of the music data transmission process. This transmission process is realized by the system controller 20 of the navigation device 1 used by the user who is the information provider executing a program prepared in advance. Assume that the information provider is user A and the information receivers are users B and C as illustrated in FIG.

First, the user B or C who is the information receiver operates the navigation device 1 and requests the music list from the user A who is the information provider. The navigation device la of the user A determines whether or not there is a request for a music list from another navigation device 1 (step Sl 1). If the music list request is ineffective, the process ends. When there is a request for the music list, the navigation device la of the user A sends the music list to the navigation devices 1 of all the members participating in the information sharing system 100 (that is, all users who are logged in). Transmit (step S12). In this example, the music list is transmitted to the navigation devices 1b and lc of the users B and C.

[0047] Next, when the user who has received the music list views the music list and sends a request for the music to be played, the navigation device of the information provider receives it (step S13; Yes), The total number of requests is displayed on the navigation device la display 44 (Step S14). The request count result indicates the number of requests for each song in the song list. Then, the user A sees the result of the request and designates the music to be transmitted, and the navigation device la receives the designation (step S15). The navigation device la transmits the music data designated by the user A to all the members (step S16). In this way, the music requested by a specific user who is a member of the information sharing system is transmitted to the navigation device 1 of the member and reproduced. Note that the music data transmitted to each navigation device 1 in step S16 can be stream data. As a result, the user of each navigation device 1 can immediately listen to the transmitted music.

FIG. 5 shows a flowchart of music data reception processing. This transmission process is realized by the system controller 20 of the navigation device 1 used by the user who is the information receiver executing a program prepared in advance. As illustrated in FIG. 2, it is assumed that the information provider is user A and the information receivers are users B and C.

[0049] First, user B who is an information receiver operates navigation device lb to request a song list from user A's navigation device la (step S21), and receives the song list (step S21). S22). Next, when user B refers to the received music list and designates the music to be played back (step S23; Yes), navigation device lb sends a playback request for that music to user A's navigation device la. (Step S24). Then, the navigation device lb of the user B receives and reproduces the music data transmitted from the navigation device la of the user A.

[0050] Since the information provider is set to transmit music data to the member, the navigation device lc of user C can also receive and play the music requested by user B. In this way, if one of the members requests a music list from a user who is an information provider, and one of the users who has received the music list requests a user who is an information provider to play music, All members of shared system 100 can get the music. Also, by providing song data as stream data, members can listen to the same song almost simultaneously.

[0051] In the above example, in step S12, the navigation system 1 of the information provider is ^ Power of sending song lists to members Alternatively, you can send song lists only to certain members, including at least the member who requested the song list in step S11.

[0052] Further, in the above example, the result of request summarization is displayed in step S14, and finally the music to be transmitted by the user is designated from among them. Instead, the requested information may be transmitted to each member in order, without the information provider's navigation device 1 displaying the result of request aggregation. In addition, the information provider's navigation device 1 is notified of the request and notified, and the requested song data of the requested song is transmitted only for the request that is confirmed by the information provider user. It is good as well.

[0053] In the above example, the power of transmitting music data to all members in step S16. Instead, the music data is transmitted only to a specific member including at least the member who requested the music. It does not matter.

[0054] [Display screen example]

Next, an example of a display screen displayed to the user during the music data transmission / reception operation will be described. Hereinafter, the operation procedure by the user will be described with reference to the display screen example of the navigation device 1.

FIG. 6 (a) shows a display screen example of the navigation device lb used by the user B. In this example, it is assumed that users A to C log in to the communication network using navigation devices la to Lc as shown in FIG. 2 and are members of the information sharing system. In this example, it is assumed that each of the users A to C is performing a so-called chat using the communication network of the information sharing system 100. Note that chatting generally means that multiple users who are accessing the Internet or personal computer conversations in real time using characters on the screen. In this example, a user uses the navigation device 1 as a terminal device, and exchanges character string (text) data with a user who uses another navigation device in real time. The character information input by a certain user is basically displayed on the navigation devices 1 of all users who are participating in the chat. The display screen 130 is displayed on the display 44 of the navigation device lb of the user B as shown in FIG. 6 (a). Display screen 130 includes a map, various input buttons, and a chat message. Specifically, the display screen 130 displays a map near the current position of the vehicle including the road 131 on the map, the current position mark 132 indicating the current position of the vehicle, and the route currently being guided , And current position marks 134a and 134c of other members' vehicles participating in the chat are displayed. The current position mark 134a corresponds to the user A's vehicle equipped with the navigation device la, and the current position mark 134c corresponds to the user C's vehicle equipped with the navigation device lc. Further, a message window 145 showing a chat message is displayed on the display screen 130.

[0057] Various input buttons are displayed on the left and right positions of the display screen 130. The music list request button 136 is used when the user who is the information receiver requests the user who is the information provider to transmit the music list. The music request button 137 is used when a user who is an information receiver requests a music from a user who is an information provider. The request display button 138 is used to display a tabulated result of requests for music transmitted from another user or user power as an information provider, and to transmit music data. The music playback button 139 is used when a user who is an information provider proactively transmits and plays music data to each member without a request from a user who is an information receiver.

[0058] In this example, the navigation device of the information provider transmits music data to all members of the information sharing system 100 in principle. However, it is also possible to send music data only to specific members by selecting user A who is the information provider.

[0059] First, on the display screen 130 shown in FIG. 6 (a), when the user B who is the information receiver presses the music list request button 136, the music list request is sent to the navigation device lb force navigation device la. In response to this, the music list is transmitted from the navigation device la to the navigation device lb. When the music list is received, as shown in FIG. 6 (a), the navigation device lb notifies the user B by displaying that fact in a message window 145, for example. Next, when the user B presses the music request button 137, a music list screen 140 shown in FIG. 6B is displayed on the display 44 of the navigation device lb. On the music list screen 140, a music list including a plurality of music is displayed, and the user can select the music bar 141 by operating the input device 60 such as a remote control touch panel. When User B selects one or more songs that he / she wants to play, selects the songs using the song bar 141, and presses the send button 142, the request for the song selected by User B is User A's napping device. sent to la. Thereafter, the display screen 130 shown in FIG. 6 (a) is displayed on the display 44 of the navigation device lb.

[0061] When the navigation device la of the user A receives the music request from the navigation device lb of the user B, as shown in FIG. 7 (a), it indicates that the music request has been received in the message window 145. Display a message. When the user A presses the request display button 138, as shown in FIG. 7 (b), a screen 160 showing the totaled result of requests is displayed on the display 44. On the screen 160, the number of requests is displayed in each music bar 141. User A refers to the total result of the request, selects the music bar 141, selects the music to be transmitted to the member, and presses the send button 142. As a result, the music data of the music selected by the user A is transmitted to the navigation device 1 of the member of the information sharing system 100 and reproduced.

[0062] In the above embodiment, user A is always an information provider, but in reality the roles of the information provider and the information receiver change from moment to moment. In other words, at a certain point in time, among users of a plurality of navigation devices constituting the information sharing system, the user who has received a request for another user-powered music list becomes an information provider, and all other users are other users. Becomes an information recipient. When a song list request is made to another user at the next time, the user who receives the request becomes an information provider. Therefore, members of the information sharing system can request the music possessed by other members and play them on their navigation devices as necessary.

As described above, in this embodiment, in the information sharing system, when a user who is an information receiver requests a music list from a user who is an information provider, the information sharing system is configured. Song list is sent to all users who have Can be done. When each user makes a music request, the navigation device of the user who is the information provider displays the result of the request. The result of the request aggregation is a kind of questionnaire for each user, and the user who is the information provider can see the result of the aggregation and transmit music that satisfies the members.

[0064] [Modification]

In the above example, music data is cited as information shared by members of the information sharing system, but the present invention is not limited to this embodiment. For example, information on points that should be registered in the navigation device can be shared. For example, a user who is an information provider provides a list of registration points to other members, and each member selects a destination he / she wants to go to and makes a request to the information provider. The information provider determines the destination with reference to the result of the request, and transmits the location information of the destination and the route information to Z or the destination to the navigation device of the member. Thereby, the same destination can be set in the navigation devices of all members.

In the above-described embodiment, the music list and the music request, and the music list and the music data are transmitted / received mainly via the server. However, as described with reference to FIG. It is also possible to send and receive data using P2P communication without going through. In particular, the music list request, the music data transmission request, and the music list itself are suitable for transmission by P2P because the data amount is small compared to the music data.

Industrial applicability

[0066] The present invention can be used in a navigation apparatus for a moving body represented by a vehicle or the like.
