　図２は、ナビゲーション装置３０のハードウェア構成を示す図である。図２のように、ナビゲーション装置３０は、少なくとも処理回路５０１、メモリ５０２、入出力インターフェイス５０３を含む構成となっている。 FIG. 2 is a diagram showing a hardware configuration of the navigation device 30. As shown in FIG. As shown in FIG. 2, the navigation device 30 includes at least a processing circuit 501, a memory 502, and an input / output interface 503.
　入力装置３０１、表示装置３０２、音声出力装置３０３および通信装置３０４は、入出力インターフェイス５０３に接続される。図１では、入力装置３０１、表示装置３０２、音声出力装置３０３および通信装置３０４が、ナビゲーション装置３０に外付けされた構成としたが、それらのハードウェアがナビゲーション装置３０の内部に配設されるようにしてもよい。 The input device 301, the display device 302, the audio output device 303, and the communication device 304 are connected to the input / output interface 503. In FIG. 1, the input device 301, the display device 302, the audio output device 303, and the communication device 304 are configured to be externally attached to the navigation device 30, but their hardware is arranged inside the navigation device 30. You may do it.
　ナビゲーション装置３０における入力処理部３１、出力処理部３２、ナビゲーション部３３、情報取得部３４および記憶部３５の各機能は、処理回路５０１により実現される。すなわち、ナビゲーション装置３０は、インターネット端末装置１０における検索履歴または閲覧履歴から推定されたユーザの行き先に関連する情報（推定行き先情報）を取得し、その推定行き先情報をユーザが視聴できるように出力するための処理回路５０１を備える。処理回路５０１は、メモリ５０２に格納されるプログラムを実行するＣＰＵ（Central Processing Unit、中央処理装置、処理装置、演算装置、マイクロプロセッサ、マイクロコンピュータ、プロセッサ、ＤＳＰともいう）である。 The functions of the input processing unit 31, the output processing unit 32, the navigation unit 33, the information acquisition unit 34, and the storage unit 35 in the navigation device 30 are realized by the processing circuit 501. That is, the navigation device 30 acquires information (estimated destination information) related to the user's destination estimated from the search history or browsing history in the Internet terminal device 10 and outputs the estimated destination information so that the user can view it. A processing circuit 501 is provided. The processing circuit 501 is a CPU (also referred to as a central processing unit, a central processing unit, a processing unit, a processing unit, a microprocessor, a microcomputer, a processor, and a DSP) that executes a program stored in the memory 502.
　入力処理部３１、出力処理部３２、ナビゲーション部３３、情報取得部３４および記憶部３５の機能は、ソフトウェア、ファームウェア、またはソフトウェアとファームウェアとの組み合わせにより実現される。ソフトウェアやファームウェアはプログラムとして記述され、メモリ５０２に格納される。処理回路５０１は、メモリ５０２に記憶されたプログラムを読み出して実行することにより、各部の機能を実現する。すなわち、ナビゲーション装置３０は、インターネット端末装置１０における検索履歴または閲覧履歴から推定されたユーザの行き先に関連する情報（推定行き先情報）を取得するステップと、その推定行き先情報をユーザが視聴できるように出力するステップとが、結果的に実行されることになるプログラムを格納するためのメモリ５０２を備える。また、これらのプログラムは、入力処理部３１、出力処理部３２、ナビゲーション部３３、情報取得部３４および記憶部３５が行う処理の手順や方法をコンピュータに実行させるものであるともいえる。ここで、メモリ５０２は、例えば、ＲＡＭ（Random-Access Memory）、ＲＯＭ（Read-Only Memory）、フラッシュメモリ、ＥＰＲＯＭ（Erasable Programmable Read-Only Memory）、ＥＥＰＲＯＭ（Electrically Erasable Programmable Read-Only Memory）等の、不揮発性または揮発性の半導体メモリや、磁気ディスク、フレキシブルディスク、光ディスク、コンパクトディスク、ミニディスク、ＤＶＤ（Digital Versatile Disc）等が該当する。なお、記憶部３５の記憶領域は、メモリ５０２の一部を用いて実現される。 The functions of the input processing unit 31, the output processing unit 32, the navigation unit 33, the information acquisition unit 34, and the storage unit 35 are realized by software, firmware, or a combination of software and firmware. Software and firmware are described as programs and stored in the memory 502. The processing circuit 501 implements the functions of each unit by reading and executing a program stored in the memory 502. That is, the navigation device 30 obtains information related to the user's destination estimated from the search history or browsing history in the Internet terminal device 10 (estimated destination information), and allows the user to view the estimated destination information. The step of outputting comprises a memory 502 for storing a program to be executed as a result. In addition, it can be said that these programs cause the computer to execute procedures and methods of processing performed by the input processing unit 31, the output processing unit 32, the navigation unit 33, the information acquisition unit 34, and the storage unit 35. Here, the memory 502 is, for example, a RAM (Random-Access Memory), a ROM (Read-Only Memory), a flash memory, an EPROM (Erasable Programmable Read-Only Memory), an EEPROM (Electrically-Erasable Programmable Read-Only Memory), or the like. Non-volatile or volatile semiconductor memories, magnetic disks, flexible disks, optical disks, compact disks, mini disks, DVDs (Digital Versatile Discs), and the like are applicable. Note that the storage area of the storage unit 35 is realized by using a part of the memory 502.
　また、サーバー２０のハードウェア構成も、基本的には図２と同様の構成となっている。すなわち、サーバー２０は、インターネット端末装置１０における検索履歴または閲覧履歴からユーザの行き先を推定し、推定されたユーザの行き先に関連する情報（推定行き先情報）を取得し、その推定行き先情報をナビゲーション装置３０へ送信するための処理回路５０１と、それらの処理を処理回路５０１に実行させるためのプログラムを記憶したメモリ５０２とを備えている。 The hardware configuration of the server 20 is basically the same as that shown in FIG. That is, the server 20 estimates the user's destination from the search history or browsing history in the Internet terminal device 10, acquires information (estimated destination information) related to the estimated user's destination, and uses the estimated destination information as the navigation device. 30 and a memory 502 that stores a program for causing the processing circuit 501 to execute these processes.
　以下、ナビゲーションシステム１００におけるインターネット端末装置１０、サーバー２０およびナビゲーション装置３０の各動作を説明する。 Hereinafter, each operation of the Internet terminal device 10, the server 20, and the navigation device 30 in the navigation system 100 will be described.
　図３は、インターネット端末装置１０の動作を示すフローチャートである。インターネット端末装置１０は、ユーザがブラウザ１１を用いてインターネット検索またはウェブページ閲覧を行うと（ステップＳ１１）、その検索履歴および閲覧履歴をサーバー２０へ送信する（ステップＳ１２）。 FIG. 3 is a flowchart showing the operation of the Internet terminal device 10. When the user performs Internet search or web page browsing using the browser 11 (step S11), the Internet terminal device 10 transmits the search history and browsing history to the server 20 (step S12).
　図４は、サーバー２０の動作を示すフローチャートである。サーバー２０が、インターネット端末装置１０が図３のステップＳ１２で送信したユーザの検索履歴および閲覧履歴を受信すると（ステップＳ２１）、行き先推定部２１は、それらの内容を分析してユーザの行き先を推定する（ステップＳ２２）。例えば、検索履歴に地名、施設名、イベント名などが含まれていれば、それらの所在地や開催地がユーザの行き先として推定される。また、閲覧履歴に、特定の観光地、施設、イベントなどのウェブサイトが含まれていれば、それに対応する場所がユーザの行き先として推定される。 FIG. 4 is a flowchart showing the operation of the server 20. When the server 20 receives the user search history and browsing history transmitted by the Internet terminal device 10 in step S12 of FIG. 3 (step S21), the destination estimation unit 21 analyzes the contents and estimates the user destination. (Step S22). For example, if a place name, a facility name, an event name, etc. are included in the search history, those locations and venues are estimated as user destinations. Further, if the browsing history includes websites such as specific sightseeing spots, facilities, and events, a corresponding place is estimated as the destination of the user.
　行き先推定部２１は、ユーザの行き先として推定する場所（以下、「行き先候補地」という）を１箇所に絞り込む必要はなく、複数の行き先候補地を挙げてもよい。行き先候補地が非常に多く挙げられる場合には、例えば、検索頻度や閲覧頻度が比較的高いものに絞り込んだり、行き先候補が集中した地域全体を１つの行き先候補地に変換したりして、行き先候補地の数を少なくしてもよい。 The destination estimation unit 21 does not need to narrow down the place estimated as the user's destination (hereinafter referred to as “destination candidate place”) to one place, and may list a plurality of destination candidates. If there are too many potential destinations, for example, narrow down to those with a relatively high search frequency or browsing frequency, or convert the entire area where the destination candidates are concentrated into one destination candidate. The number of candidate sites may be reduced.
　行き先推定部２１によりユーザの行き先が推定されると、情報収集部２２が、インターネット４０から、推定されたユーザの行き先に関連する情報（推定行き先情報）を検索して収集する（ステップＳ２３）。先に述べたように、推定行き先情報は、推定されたユーザの行き先（行き先候補地）およびその周辺の観光スポット情報、イベント情報、グルメ情報およびそれらの評価情報などである。 When the destination of the user is estimated by the destination estimation unit 21, the information collection unit 22 searches and collects information (estimated destination information) related to the estimated user's destination from the Internet 40 (step S23). As described above, the estimated destination information includes the estimated destination of the user (destination candidate site) and its surrounding tourist spot information, event information, gourmet information, and evaluation information thereof.
　行き先推定部２１による推定行き先情報の収集が完了すると、サーバー２０はナビゲーション装置３０との通信が可能かどうか確認する（ステップＳ２４）。サーバー２０は、ナビゲーション装置３０との通信可能でなければ（ステップＳ２４でＮＯ）、通信可能になるのを待ち、通信可能になると（ステップＳ２４でＹＥＳ）、行き先推定部２１が収集した推定行き先情報をナビゲーション装置３０へ送信する（ステップＳ２５）。 When the collection of the estimated destination information by the destination estimation unit 21 is completed, the server 20 confirms whether communication with the navigation device 30 is possible (step S24). If the server 20 is not communicable with the navigation device 30 (NO in step S24), the server 20 waits for communication, and if communication is possible (YES in step S24), the estimated destination information collected by the destination estimation unit 21. Is transmitted to the navigation device 30 (step S25).
　図５は、ナビゲーション装置３０の動作、特に、推定行き先情報の受信および提示に係る動作を示すフローチャートである。サーバー２０が図４のステップＳ２５で送信した推定行き先情報は、通信装置３０４を通してナビゲーション装置３０の情報取得部３４に受信される（ステップＳ３１）。情報取得部３４に受信された推定行き先情報は、記憶部３５に記憶される（ステップＳ３２）。 FIG. 5 is a flowchart showing the operation of the navigation device 30, particularly the operation related to the reception and presentation of the estimated destination information. The estimated destination information transmitted by the server 20 in step S25 of FIG. 4 is received by the information acquisition unit 34 of the navigation device 30 through the communication device 304 (step S31). The estimated destination information received by the information acquisition unit 34 is stored in the storage unit 35 (step S32).
　記憶部３５に推定行き先情報が記憶されると、入力処理部３１は、ユーザから推定行き先情報の提示要求を受けたか否かを確認する（ステップＳ３３）。ユーザから推定行き先情報の提示要求を受けた場合（ステップＳ３３でＹＥＳ）、出力処理部３２は、表示装置３０２または音声出力装置３０３を用いて推定行き先情報をユーザに提示する（ステップＳ３４）。その後、情報取得部３４は、サーバー２０から新たな推定行き先情報が送信されたかを確認する（ステップＳ３５）。 When the estimated destination information is stored in the storage unit 35, the input processing unit 31 confirms whether or not the estimated destination information presentation request has been received from the user (step S33). When the estimated destination information presentation request is received from the user (YES in step S33), the output processing unit 32 presents the estimated destination information to the user using the display device 302 or the voice output device 303 (step S34). Thereafter, the information acquisition unit 34 confirms whether new estimated destination information is transmitted from the server 20 (step S35).
　ユーザから推定行き先情報の提示要求を受けていない場合は（ステップＳ３３でＮＯ）、推定行き先情報の提示処理（ステップＳ３４）は行わないが、その場合も、情報取得部３４は、サーバー２０から新たな推定行き先情報が送信されたかを確認する（ステップＳ３５）。 When the estimated destination information presentation request has not been received from the user (NO in step S33), the estimated destination information presentation process (step S34) is not performed. It is confirmed whether or not the estimated destination information has been transmitted (step S35).
　サーバー２０から新たな推定行き先情報が送信された場合は（ステップＳ３５でＹＥＳ）、ステップＳ３１へ戻り、新たな推定行き先情報を受信する。サーバー２０から新たな推定行き先情報が送信されていない場合は（ステップＳ３５でＮＯ）、ステップＳ３３へ戻り、ユーザから推定行き先情報の提示要求が入力されるのを待つ。 If new estimated destination information is transmitted from the server 20 (YES in step S35), the process returns to step S31 and receives new estimated destination information. If new estimated destination information has not been transmitted from the server 20 (NO in step S35), the process returns to step S33 and waits for a request to present estimated destination information from the user.
　図４で説明したように、サーバー２０は、ナビゲーション装置３０との通信が可能になるのを待ってから推定行き先情報を送信するため、基本的に、ナビゲーション装置３０が推定行き先情報を受信するタイミングは、ナビゲーション装置３０が起動した直後、より具体的にはナビゲーション装置３０とサーバー２０との通信が可能になった直後となる。そのため、ナビゲーション装置３０は、ユーザが目的地等を設定する前に、推定行き先情報を取得できる。ただし、サーバー２０が推定行き先情報をナビゲーション装置３０へ送信するタイミングは、ナビゲーション装置３０の起動直後だけではない。ナビゲーション装置３０が起動した後も、サーバー２０は、推定行き先情報を更新するごと（すなわち図４の動作が行われるごと）に推定行き先情報をナビゲーション装置３０へ送信しようとする。図５のステップＳ３５は、更新後の新たな推定行き先情報を受信するための処理である。 As described with reference to FIG. 4, the server 20 waits until communication with the navigation device 30 becomes possible and then transmits the estimated destination information. Therefore, basically, the timing at which the navigation device 30 receives the estimated destination information. Is immediately after the navigation device 30 is activated, more specifically, immediately after the communication between the navigation device 30 and the server 20 becomes possible. Therefore, the navigation apparatus 30 can acquire estimated destination information before the user sets a destination or the like. However, the timing at which the server 20 transmits the estimated destination information to the navigation device 30 is not only immediately after the navigation device 30 is activated. Even after the navigation device 30 is activated, the server 20 tries to transmit the estimated destination information to the navigation device 30 every time the estimated destination information is updated (that is, every time the operation of FIG. 4 is performed). Step S35 in FIG. 5 is a process for receiving the updated new estimated destination information.
　ナビゲーション装置３０は、ユーザが入力装置３０１を用いて推定行き先情報の提示要求を容易に入力できるように構成されている。また、図５での説明は省略したが、ユーザは、ナビゲーション装置３０が提示した推定行き先情報を視聴した後、その推定行き先情報を参考にして、ナビゲーション部３３に設定する目的地や経由地、経路などを容易に選択できるように構成されている。 The navigation device 30 is configured so that the user can easily input a request for presenting estimated destination information using the input device 301. Although the description in FIG. 5 is omitted, the user views the estimated destination information presented by the navigation device 30, and then refers to the estimated destination information to set the destination or waypoint set in the navigation unit 33, It is configured so that a route or the like can be easily selected.
　以下では、これらを実現するための画面構成の例を示す。以下の例における「おすすめ情報」は、ユーザの推定行き先情報に相当するものである。また、入力装置３０１および表示装置３０２は、１つのタッチパネル装置を構成しているものとする。すなわち、入力装置３０１は、表示装置３０２の画面に表示されている各種のボタン（ソフトウェアキー）として実現されている。 The following shows an example of the screen configuration for realizing these. “Recommended information” in the following example corresponds to the estimated destination information of the user. Further, the input device 301 and the display device 302 constitute one touch panel device. That is, the input device 301 is realized as various buttons (software keys) displayed on the screen of the display device 302.
　ナビゲーション装置３０は、推定行き先情報をユーザが閲覧するための画面（推定行き先情報の提示要求を入力するための画面）を呼び出すための「おすすめ情報」ボタンを、表示装置３０２に表示される各画面の見やすい位置に表示させる。推定行き先情報は、目的地、経由地、経路等を選択する際に役立つ情報であるのはもちろん、目的地等を設定した後にその周辺の詳細な情報を知りたい場合にも役立つ情報である。そのため、例えば図６のような目的地または経由地の設定画面や、図７のような経路選択画面、図８のような地図表示画面（経路案内画面を含む）などに、「おすすめ情報」ボタンを表示させるとよい。 Each of the screens displayed on the display device 302 includes a “recommended information” button for calling a screen for the user to browse the estimated destination information (a screen for inputting a request for presenting the estimated destination information). It is displayed in the position where it is easy to see. The estimated destination information is useful information when selecting a destination, waypoint, route, and the like, and is also useful when it is desired to know detailed information around the destination after setting the destination. Therefore, for example, a “recommended information” button is displayed on the destination or waypoint setting screen as shown in FIG. 6, the route selection screen as shown in FIG. 7, the map display screen as shown in FIG. 8 (including the route guidance screen), or the like. Should be displayed.

　例えば、ユーザが「おすすめ目的地」ボタンにタッチすると、図１０のように行き先候補地の一覧が表示される。また、ユーザが「おすすめイベント」ボタンにタッチすると、図１１のように行き先候補地の周辺で開催されているイベントの一覧が表示される。同様に、ユーザが「おすすめ飲食店」ボタンにタッチすると、図１２のように行き先候補地の周辺の飲食店の一覧が表示される。ユーザが「おすすめ宿泊施設」ボタンにタッチすると、図１３のように行き先候補地の周辺の宿泊施設の一覧が表示される。 For example, when the user touches the “recommended destination” button, a list of destination candidates is displayed as shown in FIG. When the user touches the “recommended event” button, a list of events held in the vicinity of the destination candidates is displayed as shown in FIG. Similarly, when the user touches the “recommended restaurant” button, a list of restaurants in the vicinity of the destination candidates is displayed as shown in FIG. When the user touches the “recommended accommodation facility” button, a list of accommodation facilities in the vicinity of the candidate destination location is displayed as shown in FIG.
　図１０～図１３の各画面において、「情報を見る」ボタンのいずれかにユーザがタッチすると、それに対応する行き先候補地、イベント、飲食店または宿泊施設に関する推定行き先情報が、表示装置３０２または音声出力装置３０３から出力される。それにより、ユーザは、推定行き先情報を視聴することができる。推定行き先情報の視聴が終わると、再び元の画面（図１０～図１３のいずれか）に戻る。 In each of the screens of FIGS. 10 to 13, when the user touches one of the “view information” buttons, the estimated destination information related to the candidate destination location, event, restaurant, or accommodation facility corresponding thereto is displayed on the display device 302 or the voice. Output from the output device 303. Thereby, the user can view the estimated destination information. When viewing of the estimated destination information ends, the original screen (any of FIGS. 10 to 13) is restored.
　また、図１０～図１３の各画面において、「目的地に設定」ボタンにユーザがタッチすると、それに対応する先候補地の場所、イベントの開催地、飲食店の所在地または宿泊施設の所在地を、目的地としてナビゲーション部３３に設定することができる。このような画面構成により、ユーザは、推定行き先情報を視聴およびそれに対応した目的地の設定を容易に行うことができる。なお、ここではユーザが、推定行き先情報を考慮して目的地に設定する例を示したが、同様の方法により、経由地や経路を設定できるようにしてもよい。 10 to 13, when the user touches the “set to destination” button, the corresponding destination location, event location, restaurant location or accommodation location is displayed. It can be set in the navigation unit 33 as a destination. With such a screen configuration, the user can easily view the estimated destination information and set a destination corresponding to the estimated destination information. Although an example in which the user sets the destination in consideration of the estimated destination information is shown here, the waypoint and the route may be set by the same method.
　実施の形態１に係るナビゲーションシステム１００によれば、行き先推定部２１はインターネット端末装置１０におけるユーザの検索履歴または閲覧履歴からユーザの行き先を推定するため、ユーザが行ったことのない場所でも行き先として推定することができる。また、情報収集部２２が収集した推定行き先情報が、ナビゲーション装置３０に転送されることで、ユーザは推定された行き先の最新の情報を容易に閲覧することができる。さらに、サーバー２０からナビゲーション装置３０へ送られる情報は、行き先推定部２１によって推定された行き先に関する情報に絞り込まれているため、サーバー２０からナビゲーション装置３０へ送られるデータ量は抑えられる。 According to the navigation system 100 according to the first embodiment, the destination estimation unit 21 estimates the user's destination from the user's search history or browsing history in the Internet terminal device 10, so that it can be used as a destination even where the user has never been. Can be estimated. Further, the estimated destination information collected by the information collecting unit 22 is transferred to the navigation device 30, so that the user can easily browse the latest information on the estimated destination. Furthermore, since the information sent from the server 20 to the navigation device 30 is narrowed down to information related to the destination estimated by the destination estimation unit 21, the amount of data sent from the server 20 to the navigation device 30 can be suppressed.
　＜実施の形態２＞
　実施の形態１では、ユーザの行き先を推定する行き先推定部２１と、推定行き先情報を収集する情報収集部２２とを含む情報収集装置を、サーバー２０上で実現した構成のナビゲーションシステム１００を示したが、ナビゲーションシステム１００の構成はこれに限られない。例えば、図１４のように、行き先推定部２１および情報収集部２２をインターネット端末装置１０上で実現することで、情報収集装置をインターネット端末装置１０に内蔵させてもよい。 <Embodiment 2>
In the first embodiment, the navigation system 100 having a configuration in which the information collection device including the destination estimation unit 21 that estimates the destination of the user and the information collection unit 22 that collects the estimated destination information is realized on the server 20 is shown. However, the configuration of the navigation system 100 is not limited to this. For example, as shown in FIG. 14, the information collection device may be built in the Internet terminal device 10 by realizing the destination estimation unit 21 and the information collection unit 22 on the Internet terminal device 10.
　図１４のナビゲーションシステム１００では、ブラウザ１１における検索履歴または閲覧履歴からユーザの行き先を推定する行き先推定部２１としての処理、および、推定されたユーザの行き先に関する情報（推定行き先情報）を収集する情報収集部２２としての処理が、インターネット端末装置１０上で行われる。そして、情報収集部２２により収集された推定行き先情報は、インターネット端末装置１０からインターネット４０を介してナビゲーション装置３０へと送られる。実施の形態１のナビゲーションシステム１００に比べると、インターネット端末装置１０にかかる負荷が大きくなるが、実施の形態１と同様の効果が得られる。 In the navigation system 100 of FIG. 14, information as a destination estimation unit 21 that estimates a user's destination from the search history or browsing history in the browser 11 and information that collects information (estimated destination information) about the estimated user's destination. Processing as the collection unit 22 is performed on the Internet terminal device 10. The estimated destination information collected by the information collecting unit 22 is sent from the Internet terminal device 10 to the navigation device 30 via the Internet 40. Compared with the navigation system 100 of the first embodiment, the load on the Internet terminal device 10 is increased, but the same effect as the first embodiment can be obtained.
　また、図１４のナビゲーションシステム１００でも、インターネット端末装置１０からナビゲーション装置３０への推定行き先情報の送信を、（行き先推定部２１および情報収集部２２を有しない）サーバー２０を通して行ってもよい。その場合、ユーザがインターネット端末装置１０の電源を切った後にナビゲーション装置３０を起動させる場合でも、ナビゲーション装置３０はサーバー２０から推定行き先情報を受信することができる。 Further, in the navigation system 100 of FIG. 14, the estimated destination information may be transmitted from the Internet terminal device 10 to the navigation device 30 through the server 20 (which does not include the destination estimation unit 21 and the information collection unit 22). In that case, even when the user activates the navigation device 30 after turning off the power of the Internet terminal device 10, the navigation device 30 can receive the estimated destination information from the server 20.
　また、図１５のように、インターネット端末装置１０とナビゲーション装置３０との間の通信を、例えばユーザの自宅内のＬＡＮ（Local Area Network）４１を通して行ってもよい。この場合、ナビゲーション装置３０に接続された通信装置３０４は、無線または有線のＬＡＮ端末となる。 Further, as shown in FIG. 15, communication between the Internet terminal device 10 and the navigation device 30 may be performed through a LAN (Local Area Network) 41 in the user's home, for example. In this case, the communication device 304 connected to the navigation device 30 is a wireless or wired LAN terminal.
　図１５のナビゲーションシステム１００では、ナビゲーション装置３０が推定行き先情報を取得できるエリアがＬＡＮ４１の通信圏内（ユーザの自宅内やそれに隣接した車庫内など）に制限されるが、ナビゲーション装置３０は、起動時に推定行き先情報を取得するように構成されていれば、ほぼ確実に推定行き先情報を取得できる。また、図１５の構成は、システムの低コスト化にも寄与できる。また、ＬＡＮ４１に代えて、Bluetooth（登録商標）など、他の方式の近距離通信システムを用いてもよい。 In the navigation system 100 of FIG. 15, the area where the navigation device 30 can acquire the estimated destination information is limited to the communication area of the LAN 41 (such as in the user's home or in the garage adjacent to the LAN 41). If the estimated destination information is configured to be acquired, the estimated destination information can be acquired almost certainly. Further, the configuration of FIG. 15 can contribute to the cost reduction of the system. Further, in place of the LAN 41, other short-range communication systems such as Bluetooth (registered trademark) may be used.
