Description

情報表示装置および情報表示装置の情報表示方法Information display device and information display method of information display device
　本発明は、情報表示装置および情報表示装置の情報表示方法に関し、特に、手軽に情報を閲覧できる情報表示装置および情報表示装置の情報表示方法に関する。 The present invention relates to an information display device and an information display method for the information display device, and more particularly, to an information display device for easily browsing information and an information display method for the information display device.
　近年、パーソナルコンピュータの動作速度の向上、ネットワークインフラの普及、データストレージの大容量化と低価格化等に伴い、従来は紙への印刷物（以下、紙文書と言う）で提供された文書や画像等の情報を、より簡便な電子情報として入手、閲覧できる機会が増大している。 In recent years, documents and images that have been provided on paper (hereinafter referred to as paper documents) have been improved with the increase in the operating speed of personal computers, the spread of network infrastructure, and the increase in capacity and price of data storage. The opportunity for obtaining and browsing such information as simpler electronic information is increasing.
　このような電子情報のより自由な閲覧方法として、情報表示装置の一種で、例えば電子ブック等と呼ばれる、持ち運びに便利で、読む姿勢が制限されない小型、薄型の電子情報端末が開発されている。しかし、電子情報端末で電子情報を閲覧するのは、紙文書で閲覧するのに比べて問題が多い。 As a more free browsing method of such electronic information, a kind of information display device, for example, an electronic book or the like, which is a small and thin electronic information terminal that is convenient to carry and is not restricted in reading posture, has been developed. However, browsing electronic information with an electronic information terminal is more problematic than browsing with paper documents.
　１例として、紙文書を読む場合には、読者は、紙文書を読み進めながら、後で参照したい表記があった場合、文書を手で持ちつつ、参照したい表記があるページ間に指を挟む「指しおり」と言うしぐさを行う。 As an example, when reading a paper document, if a reader has a notation that he / she wants to refer to later while reading the paper document, he / she holds the document in his / her hand and holds his / her finger between the pages having the notation to be referred to. Do a gesture that says "pointing".
　「指しおり」は、紙のしおり等の補助の道具を必要とせず、参照する場合にすぐに目的のページを開けることができ、参照するページを開いた場合に、読み進めていた元のページに自然に「指しおり」を挟んでいる状態となり、元のページにすぐに戻れる等、便利である。さらに、手を離せば「指しおり」の解除が可能で、しおりを挟む、外す、といった操作を意識せずに行うことができる。 “Pointer” does not require an auxiliary tool such as a paper bookmark, and the target page can be opened immediately when it is referenced, and the original page that was read when the reference page is opened. It is convenient that the user can naturally put a “pointer” between them and immediately return to the original page. Furthermore, the “pointing” can be released by releasing the hand, and operations such as pinching and removing the bookmark can be performed without being aware of the operation.
　従来から、電子情報端末のためのしおり機能として、例えば、複数の釦にリンクして目的のページを記憶し、再度この釦を押すと目的のページを開くしおり機能が実現されている。 Conventionally, as a bookmark function for an electronic information terminal, for example, a bookmark function that links to a plurality of buttons, stores a target page, and presses the button again to realize the target page is realized.
　また、例えば特許文献１には、画面上のページにしおりをつけるスイッチと、しおりの一覧を表示する画面と情報を表示する画面との２つの画面を備えた電子ブックにおいて、しおりの一覧から選択された画面を、情報を表示する画面に表示する方法が提示されている。 Further, for example, in Patent Document 1, an electronic book having two screens, a switch for attaching a bookmark to a page on a screen, a screen for displaying a list of bookmarks, and a screen for displaying information, is selected from a list of bookmarks. A method for displaying the displayed screen on a screen for displaying information is presented.
特開２００１－１０１２０２号公報JP 2001-101202 A
　しかしながら、上述した複数の釦によるしおり機能の例では、目的のページは容易に開けるが、読み進んでいた元のページに容易に戻る機能がなく、予め元のページにも釦を割り付けてしおりを付与する動作が必要である。 However, in the example of the bookmark function with a plurality of buttons described above, the target page can be easily opened, but there is no function to easily return to the original page that has been read, and the button is assigned to the original page in advance. The operation to give is necessary.
　また、特許文献１の方法では、しおりの付与は容易であるが、目的のページの閲覧にはしおりを選択する操作が必要で、「指しおり」に比べると不便である。さらに、しおりの付与も文書と同時に記憶されるため、一時的に記憶したい場合には、しおりの削除を行う必要があり、不便である。 In addition, in the method of Patent Document 1, it is easy to assign a bookmark, but an operation for selecting a bookmark is necessary for browsing a target page, which is inconvenient compared to “pointing”. Furthermore, since the bookmark is also stored at the same time as the document, it is inconvenient to delete the bookmark if it is to be stored temporarily.
　本発明は、上記事情に鑑みてなされたもので、簡単に、参照したい画面を開き、かつ、読み進んでいた元の画面に戻ることができる情報表示装置および情報表示装置の情報表示方法を提供することを目的とする。 The present invention has been made in view of the above circumstances, and provides an information display device and an information display method for an information display device that can easily open a screen to be referred to and return to the original screen that has been read.

In the drawings, the same or equivalent parts are denoted by the same reference numerals, and redundant description is omitted.
　最初に、本発明における情報表示装置の第１の実施の形態の構成について、図１および図２を用いて説明する。図１は、情報表示装置の第１の実施の形態の外観の１例を示す模式図である。 First, the configuration of the information display device according to the first embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a schematic diagram showing an example of the appearance of the information display device according to the first embodiment.
　図１において、情報表示装置１は、筐体の正面に表示部１０と操作部５とを備えている。表示部１０は、液晶や電気化学表示素子等で構成され、文書や画像等のユーザによって選択された閲覧したい情報を表示する。操作部５は、第１スイッチ５１、第２スイッチ５２、第３スイッチ５３、戻りスイッチ５４、送りスイッチ５５およびファイル選択スイッチ５６等で構成される。 1, the information display device 1 includes a display unit 10 and an operation unit 5 on the front surface of the housing. The display unit 10 is composed of a liquid crystal, an electrochemical display element, or the like, and displays information desired to be browsed selected by a user, such as a document or an image. The operation unit 5 includes a first switch 51, a second switch 52, a third switch 53, a return switch 54, a feed switch 55, a file selection switch 56, and the like.
　図２は、情報表示装置の第１の実施の形態の内部構成を示すブロック図である。 FIG. 2 is a block diagram showing an internal configuration of the information display device according to the first embodiment.
　図２において、情報表示装置１は、表示制御部２、操作部５、記憶部６、バス９および表示部１０等で構成されている。 2, the information display device 1 includes a display control unit 2, an operation unit 5, a storage unit 6, a bus 9, a display unit 10, and the like.
　表示制御部２は、ＣＰＵ３および表示コントローラ４等で構成されている。ＣＰＵ３は、操作部５からの操作信号を受信して、その内容に従い、表示部１０への表示の制御を表示コントローラ４に指示する。表示コントローラ４は、ＣＰＵ３からの指示に従い、表示部１０への表示を制御する。 The display control unit 2 includes a CPU 3 and a display controller 4. The CPU 3 receives the operation signal from the operation unit 5 and instructs the display controller 4 to control the display on the display unit 10 according to the content of the operation signal. The display controller 4 controls display on the display unit 10 in accordance with an instruction from the CPU 3.
　操作部５は、図１に示したように、第１スイッチ５１、第２スイッチ５２、第３スイッチ５３、戻りスイッチ５４、送りスイッチ５５およびファイル選択スイッチ５６等で構成され、各スイッチ５１～５６の出力は、ＣＰＵ３に接続されている。ここでは、各スイッチ５１～５６は、押し釦式のスイッチで構成されているとするが、その他に、静電式のタッチセンサや光センサ等を用いてもよい。 As shown in FIG. 1, the operation unit 5 includes a first switch 51, a second switch 52, a third switch 53, a return switch 54, a feed switch 55, a file selection switch 56, and the like. Is connected to the CPU 3. Here, each of the switches 51 to 56 is assumed to be a push button type switch, but an electrostatic touch sensor, an optical sensor, or the like may be used.
　第１スイッチ５１が操作される、即ち図１の第１スイッチ５１の釦が押されると、第１スイッチ５１から第１信号５１ａがＣＰＵ３に向けて送信される。第２スイッチ５２および第３スイッチ５３についても同様に、各釦が押されることで、第２信号５２ａおよび第３信号５３ａがＣＰＵ３に向けて送信される。第１スイッチ５１、第２スイッチ５２および第３スイッチ５３は、本発明の「指しおり」動作に用いられる。 When the first switch 51 is operated, that is, when the button of the first switch 51 in FIG. 1 is pressed, the first signal 51 a is transmitted from the first switch 51 to the CPU 3. Similarly, for each of the second switch 52 and the third switch 53, the second signal 52 a and the third signal 53 a are transmitted to the CPU 3 by pressing each button. The first switch 51, the second switch 52, and the third switch 53 are used for the “pointing” operation of the present invention.
　戻りスイッチ５４、送りスイッチ５５およびファイル選択スイッチ５６についても同様で、各釦が押されることで、戻り信号５４ａ、送り信号５５ａおよびファイル選択信号５６ａがＣＰＵ３に向けて送信される。戻りスイッチ５４および送りスイッチ５５は、ページ戻し動作およびページ送り動作に用いられる。ファイル選択スイッチ５６は、表示部１０に表示する情報ファイルの選択に用いられる。 The same applies to the return switch 54, the feed switch 55, and the file selection switch 56. When each button is pressed, the return signal 54a, the feed signal 55a, and the file selection signal 56a are transmitted to the CPU 3. The return switch 54 and the feed switch 55 are used for a page return operation and a page feed operation. The file selection switch 56 is used to select an information file to be displayed on the display unit 10.
　記憶部６は、第１記憶部６１、第２記憶部６２および情報記憶部６３等で構成され、第１記憶部６１と第２記憶部６２とは本発明の「指しおり」動作に用いられ、情報記憶部６３は、文書や画像等の閲覧のための情報ファイルの記憶に用いられる。 The storage unit 6 includes a first storage unit 61, a second storage unit 62, an information storage unit 63, and the like. The first storage unit 61 and the second storage unit 62 are used for the “pointing” operation of the present invention. The information storage unit 63 is used for storing an information file for browsing documents, images, and the like.
　ＣＰＵ３、表示コントローラ４および記憶部６の間の指示やデータのやりとりは、バス９を介して行われる。 Instructions and data exchange among the CPU 3, the display controller 4 and the storage unit 6 are performed via the bus 9.
　ここで、ページ戻し動作およびページ送り動作について、簡単に説明する。通常は、ユーザによってファイル選択スイッチ５６が操作されて、記憶部６の情報記憶部６３に記憶されている閲覧のための情報ファイルの何れかが選択されると、ＣＰＵ３の指示により、情報記憶部６３に記憶されている選択された情報ファイルの内の１ページ分の情報が、表示コントローラ４によって表示部１０に表示される。 Here, the page return operation and page feed operation will be briefly described. Normally, when the user operates the file selection switch 56 to select one of the information files for browsing stored in the information storage unit 63 of the storage unit 6, the information storage unit One page of information in the selected information file stored in 63 is displayed on the display unit 10 by the display controller 4.
　ここで、ユーザによって送りスイッチ５５が操作される、即ち図１の送りスイッチ５５の釦が押されると、送りスイッチ５５から送り信号５５ａがＣＰＵ３に向けて送信される。ＣＰＵ３は、送り信号５５ａを受信すると、表示部１０に表示されている情報を１ページ先に送るページ送り指示を表示コントローラ４に向けて送信する。 Here, when the feed switch 55 is operated by the user, that is, when the button of the feed switch 55 in FIG. 1 is pressed, a feed signal 55a is transmitted from the feed switch 55 to the CPU 3. When the CPU 3 receives the feed signal 55 a, the CPU 3 sends a page feed instruction for sending the information displayed on the display unit 10 one page ahead to the display controller 4.
　表示コントローラ４は、ページ送り指示を受信すると、表示部１０に表示されている１ページ分の情報の次のページの情報を、情報記憶部６３に記憶されている選択された情報ファイルから取り出して表示部１０の表示を更新する。ページ戻し動作についても同様である。 When the display controller 4 receives the page turning instruction, the display controller 4 extracts the information of the next page of the information for one page displayed on the display unit 10 from the selected information file stored in the information storage unit 63. The display on the display unit 10 is updated. The same applies to the page return operation.
　なお、ここでは、閲覧する情報ファイルは、情報記憶部６３に記憶されている閲覧のための情報ファイルの何れかからユーザによってファイル選択スイッチ５６が操作されることで選択されるとしたが、これに限るものではなく、例えば情報表示装置１がインターネットに接続されており、例えばインターネット上の図書館にある情報ファイルから必要に応じて１ページ分の情報をダウンロードして表示してもよい。 Here, the information file to be browsed is selected by operating the file selection switch 56 from any of the information files for browsing stored in the information storage unit 63. For example, the information display device 1 is connected to the Internet, and for example, information for one page may be downloaded and displayed from an information file in a library on the Internet as necessary.
　次に、本発明における情報表示装置の第１の実施の形態の動作について、図３を用いて説明する。図３は、情報表示装置の第１の実施の形態の「指しおり」動作を示すフローチャートである。 Next, the operation of the information display device according to the first embodiment of the present invention will be described with reference to FIG. FIG. 3 is a flowchart showing the “pointing” operation of the first embodiment of the information display device.
　図３において、ステップＳ１１で、ユーザによって第１スイッチ５１の釦が押されたか否かが確認される。操作されていなければ（ステップＳ１１；Ｎｏ）、ステップＳ２１に進む。操作された場合（ステップＳ１１；Ｙｅｓ）ステップＳ１３で、現在、即ち第１スイッチ５１の釦が押された時点で表示部１０に表示されている１ページ分の情報が、しおり画面情報として記憶部６の第１記憶部６１に記憶され、ステップＳ２１に進む。 In FIG. 3, it is confirmed in step S11 whether or not the button of the first switch 51 has been pressed by the user. If not operated (step S11; No), the process proceeds to step S21. When operated (step S11; Yes), in step S13, the information for one page currently displayed on the display unit 10 when the button of the first switch 51 is pressed is stored as bookmark screen information. 6 is stored in the first storage unit 61, and the process proceeds to step S21.
　ステップＳ１１およびＳ１３は、本発明におけるしおり画面情報記憶工程として機能する。これで、表示部１０に現在表示されている１ページ分の情報に「指しおり」を挟んだことになる。 Steps S11 and S13 function as a bookmark screen information storage step in the present invention. Thus, “pointing” is sandwiched between information for one page currently displayed on the display unit 10.
　ステップＳ２１で、ユーザによって第２スイッチ５２の釦が押されたか否かが確認される。操作されていなければ（ステップＳ２１；Ｎｏ）、ステップＳ３１に進む。操作された場合（ステップＳ２１；Ｙｅｓ）ステップＳ２３で、現在、即ち第２スイッチ５２の釦が押された時点で表示部１０に表示されている１ページ分の情報が、元画面情報として記憶部６の第２記憶部６２に記憶される。 In step S21, it is confirmed whether or not the user has pressed the button of the second switch 52. If not operated (step S21; No), the process proceeds to step S31. When operated (step S21; Yes), in step S23, the information for one page currently displayed on the display unit 10 at the time when the button of the second switch 52 is pressed is stored as original screen information. 6 in the second storage unit 62.
