The following embodiments can be used alone or in combination with each other. In addition, the embodiments described below may be used in combination with the above-described user interface (UI).

The present invention provides various methods related to the e-book viewing function.

The e-book is also called a digital book, and it is composed of electronic files so that it can be read out and read at any time from a portable small mobile terminal. Unlike a paper book, the e-book can quickly search for information, directly modify the information, or change the content to the latest contents, and can include not only text but also multimedia information such as sound or image. In addition, the e-book is not a simple electronic document (for example, a Word file, a PDF file, a text file, etc.) but a book constructed so that digital rights management (DRM) is added to prevent illegal copy and unauthorized distribution. In addition, there is an advantage that it is possible to carry over hundreds of electronic books according to the memory capacity of the mobile terminal.

In the following description, a user interface (UI) for storing and managing the electronic books is referred to as 'electronic bookstore' for convenience. In the electronic bookstore, not only an electronic book but also additional information such as a memo, a bookmark, a hyperlink, and a highlight can be separately stored for each electronic book. The program for reproducing the electronic book is referred to as an " electronic book reader ".

The e-book reader can play back all types of information (e. G., Text, sound, images, Internet link information, movies, notes, highlights, bookmarks, etc.) contained in the e-book. In addition, the e-book reader may not play back only information of a specific format or vice versa. As described above, it is possible to set a playback mode (for example, a text mode, a sound mode, an image mode, a text & sound dual mode, etc.) to control the output of a specific format of information, It can be described that the electronic book is displayed or reproduced according to the format of the electronic book.

For reference, the audio e-book which can be reproduced in the sound mode can convert the text e-book into audio using the TTS (Text to Speech) function, and the audio e-book and the text e-book can be synchronized. Alternatively, only a file or an audio file in which a text e-book and an audio e-book are synced can be separately downloaded. Of course, you can download files with images, audio, and text synced.

For convenience of explanation, it is assumed in the following embodiments that the e-book reader is set to the text mode. The user can launch the e-book reader and then select and play the desired e-book. In order to select the e-book, the user performs a menu call, an e-book retrieval menu selection, a folder in which the e-book is stored, an e-book list displayed in the selected folder, and a desired e-book selection process in the e-book list do. When the user selects a desired electronic book, the controller 180 loads the selected electronic book in the memory 160 and displays the selected electronic book on the screen of the electronic book reader.

Hereinafter, the functions that can be performed during playback of the electronic book will be described with reference to the accompanying drawings.

3A to 3C are diagrams for explaining a memo function of an electronic book reader according to the present invention.

As described above, the user can input a memo while the electronic book is displayed. The memo can be entered using text (e.g., typing or handwriting recognition), sound (e.g., voice recording), or an image (e.g., still image or moving picture).

For example, as shown in FIG. 3A, a user may select a memo input menu 210 and then set a memo input type (e.g., text, sound, image) (220). The control unit 180 may activate the microphone 122 or the camera 121 or display a pop-up window 240 for text input according to the selected input type. When the pop-up window is displayed, a soft keypad may be displayed 230 together. The user can use the soft keypad to input a note in the pop-up window or a note in a written form using an arbitrary input means (e.g., a pen). The control unit 180 may store the inputted memo in association with the electronic book as additional information of the electronic book.

In addition, when the note is input in a text format, a separate page may be added and input. For example, you can insert a page for entering notes on the next page (for example, page 6) of the current page (for example, page 5) of an e-book.

Also, the memo can be input simultaneously in two or more formats. For example, you can enter notes in video and text format. Or a process in which a text is input (e.g., typing or handwriting) may be photographed as a moving picture and inputted as a memo.

When the memo is inputted as described above, an icon indicating the memo type can be displayed on the electronic book. For example, as shown in FIG. 3B, when the memo is text, an icon 251 representing a text may be displayed. When the memo is an image (still image or moving image), a thumbnail image 253, , And if the note is a sound, an icon 252 representing a sound may be displayed. As described above, icons for selecting a memo format are displayed on one side 250 of the screen, and an electronic book body is displayed on one side 260 of the screen where the icon is not displayed. The icon display area 250 and the electronic book text display area 260 may be overlaid and displayed without being divided.

Although not shown in the drawing, the memo icon may be divided into an e-book reader screen, note icons may be displayed on one screen, and an e-book text may be displayed on another screen. Alternatively, a note icon may be displayed on a word or a sentence in a text of the electronic book in a superimposed manner. Or some or all of the memo contents may be overlaid on the e-book text. At this time, the memo contents are displayed dimly, and when the user selects the memo contents, the memo contents can be changed sharply. Accordingly, when displaying an electronic book, the user can select whether to display only the content of the text, display the content with the memo icon in the main text, or display the content with the content of the memo in the main text.

When the user selects the icon indicating the memo as described above, the memo contents can be outputted in a manner suited to the format of the memo. For example, if the format of the memo is text, the text is displayed in the pop-up window 254. If the format of the memo is an image, a still image or a moving picture is displayed in a pop-up window. (Step 255). Here, the transparency of the pop-up window 254 can be adjusted. Accordingly, the pop-up window can be displayed so as to overlap with the original contents of the electronic book.

In addition, since the format of the memo is divided as described above, the user can select and output the memo of the desired format. For example, as shown in FIG. 3C, only the images of the image format are listed, and one of the image memos can be selected and displayed. Alternatively, only one text memo can be selected and displayed after listing only text memos. Here, the list 255 of the memos can be displayed as an icon or displayed as a summary of the memo. At this time, it is possible to display at least any one of information related to each memo (e.g., a chapter, a paragraph, or a page) 256 in any of the above cases. That is, the contents of the desired text can be easily retrieved by referring to the memo information.

In addition, the memo may be set as a standby screen or a background screen of the mobile terminal. Here, the memo set as the idle screen or the background screen may be overlaid on the existing background screen or the idle screen, and the transparency of the memo may be adjusted to distinguish the idle screen from the idle screen.

4A to 4C are diagrams for explaining the page turning function of the electronic book reader according to the present invention.

The page of the e-book is generally handed over manually and it is also possible to turn it over automatically. However, since the speed at which a user reads an e-book is not constant, if the page is automatically turned over, there may be a time remaining or shortage before the page is turned over. Thus, in the present embodiment, the electronic book turnover function that can solve the above problems will be described.

As shown in FIG. 4A, the user can set the auto flip time option 261 before executing the page automatic flip function. For example, if the automatic turnover time is set to '10 seconds', the control unit 180 automatically flips the page of the e-book every 10 seconds. The automatic turnover time may be set differently according to the type (e. G., Cartoon, magazine, novel, etc.) 262 of the e-book.

When the automatic page turning function is executed after displaying the electronic book as described above, the control unit 180 can display the remaining time before turning the page or the elapsed time after passing the page. For example, as shown in FIG. 4B, the time information (e.g., remaining time or elapsed time) 263, 264 is displayed on one side (e.g., one side edge, one side, etc.) And the user may change the display position of the time information. Where the time information may be displayed as a number 263 or as an animated image 264. [ Accordingly, the user can adjust the speed at which the e-book is read by referring to the time information. For example, if the remaining time is not enough, the user can read the e-book as quickly as possible.

In another embodiment, if the animated image is a specific character, the character may be placed on one side of the e-book reader screen, and the effect of moving the character each time the page is moved may be set. In addition, the character and the time counting information are linked with each other to move the character from left to right or from top to bottom, so that the elapsed time and the remaining time can be confirmed at the same time. Further, it is possible to arrange two or more of the characters at different positions, and to set them to meet at a specific position in conjunction with the time counting information.

However, if there are many portions to be read as compared with the remaining time, the user can temporarily suspend automatic page turning. If the remaining time is too long, the user can immediately return to the next page. For example, as shown in FIG. 4C, if the remaining time is insufficient, the controller 180 may stop the time counting (266) if the user touches the time information displayed on the screen (265). When the touch is released, the time count can be restarted (267). When the counting of the restarted time is completed, the controller 180 can automatically pass the page (268).

On the other hand, if too much time is left even after the user reads the text of the electronic book, the user can double-touch one side of the screen and the control unit 180 can immediately complete the time count and then turn the page. As described above, even if the user arbitrarily manipulates page turning, the page automatic turning function is not released.

On the other hand, the page turning function can be operated not only by the touch method, but also by using the keypad or voice recognition. For example, the user can operate the page turning function by setting a key that can perform the same function as the touch. You can also manipulate page breaks by using commands such as 'Next', 'Previous', or 'Page Number'. For reference, the page may be set to turn to the left, flip right, flip down, or flip up.

5 is an exemplary diagram illustrating a readability improving function of the e-book reader according to the present invention.

Readability means the degree of efficiency of how easy the print is to be read. Paper books can not be used to improve readability once they are printed, but they can be used to improve readability when reading e-books . For example, you can improve readability by using the typeface, spacing, line spacing, spacing, or highlighting of e-books. In addition, functions for improving readability will be described in the following embodiments.

As a first embodiment, the user can highlight a background or text of a line or block to be touched when reading an electronic book (271). Where the highlight may include at least one of an underline, a background color, a font color, or font sizes.

In the second embodiment, only the text corresponding to the line or block to be touched by the user can be displayed (272). For example, a line or block that is not touched may be dimmed and a line or block that the user touches may be relatively clear or bright.

As a third embodiment, the control unit 180 may automatically display or highlight text corresponding to a line or a block at a predetermined time interval (step 273). For example, assuming that the page turnover time is 10 seconds and the text on the page is 10 lines, one second can automatically and sequentially display a particular line more clearly or brighter than the other lines.

As a fourth embodiment, the font size of a specific line may be automatically changed or changed to be larger (274). When the font size is changed as described above, text that can not be displayed on one line is automatically passed to the next line.

As a fifth embodiment, a specific area (for example, a magnifying glass area) can be enlarged and displayed as if a book or a newspaper are viewed with a magnifying glass (275). For example, a screen such as a size of an actual paper book may be formed, and a motion such as a gyro sensor may be used to detect movement of the terminal, thereby moving the page in all directions, thereby enlarging and displaying the contents located in the specific area. At this time, an indicator for indicating where the specific area is within the page may be displayed.

In addition, when the user rotates or tilts the mobile terminal, the controller 180 may rotate the electronic book in the lateral or longitudinal direction corresponding to the tilt angle according to the rotation angle, tilt angle, and tilt direction of the mobile terminal.

6 is an exemplary diagram illustrating the statistical functions of the electronic book reader according to the present invention.

Every time the user displays an e-book to read 281, the control unit 180 reads the 'reading time', 'the type of book read', 'the number of books read', 'the total time taken to read a book' , Or 'purchase cost of books' by 'day / week / month / quarter / year' (282). The statistics obtained as described above may be stored in a specific area of the memory 160 (283). The statistics can be used to analyze a user's reading habits, or a reading plan can be set for a specific period.

7 is a diagram illustrating an example of a quiz function of the electronic book reader according to the present invention.

The quiz function is a kind of entertainment function that helps the user to concentrate on reading a book. The quiz may output what is already contained in the electronic book, or may be automatically generated from the contents of the electronic book. Alternatively, a quiz related to the electronic book can be downloaded and output via the Internet.

Hereinafter, a method of automatically generating the quiz will be described in the present embodiment. For example, when the user selects the quiz output menu (S101), the control unit 180 automatically generates a quiz within the range of the electronic book that the user has read so far (S102). At this time, since the control unit 180 has no perception ability, it may be difficult to generate a high-dimensional quiz to measure the user's comprehension ability. Thus, you can create a quiz, such as selecting an arbitrary paragraph or sentence in the body of an e-book, and then parenthesizing any word in that paragraph or sentence.

When the user outputs the answer sheet, the control unit 180 inputs the answer sheet (S104). If the user inputs the answer sheet (S104), the control unit 180 determines whether the answer sheet is the OMR (Optical Mark Recognition) (S105). ≪ / RTI >

The scoring may be provided in connection with the quiz providing server. And, the score result can automatically generate statistics (S106). The generated statistics are stored and may be provided to the user as a statistical data for a change in score by day, week, or month, or an average correct answer (S107). That is, the user can confirm the degree of improvement of the readability of the book by using the quiz statistics.

8 is a diagram illustrating an example of a bookmark function of an electronic book reader according to the present invention.

The bookmark function is one of the additional functions for improving the convenience of the user reading the e-book. The bookmark can be stored as a separate file and can be linked to the electronic book. For example, when displaying the e-book, a bookmark file linked to the e-book can be automatically found and displayed together with the e-book.

When a user creates a bookmark in an electronic book display (311), the bookmark can be generated by inserting multimedia contents such as text, image (still image, moving picture), icon, voice, etc. (312). For example, the e-book reader may provide various types of bookmarks by default, and a user may select a bookmark creation menu and create a new bookmark in the form of a bookmark provided as a default. The bookmark may specify a particular paragraph, line, or specific location on the current page as well as the current page.

Meanwhile, when the bookmark creation is completed as described above, the controller 180 can separately generate a bookmark information file linked to the electronic book, and the separately generated bookmark file can be transmitted to another mobile terminal. Accordingly, when the electronic book linked to the transferred bookmark file is displayed on the mobile terminal, the bookmark information may be displayed on the electronic book.

FIG. 9 is an exemplary diagram illustrating a hyperlink function of an electronic book reader according to the present invention. FIG.

The hyperlink function is one of the additional functions for improving the convenience of users reading e-books. The hyperlink function may allow a user to directly hyperlink a specific word selected in the body of the electronic book and related information (321), and automatically hyperlink using the dictionary built in the mobile terminal itself (322). (323) by automatically searching for a dictionary provided by a specified web site (e.g., a dictionary website) designated via the Internet.

The hyperlinked word may be displayed 320 to distinguish it from other unlinked words in the ebook body. In addition, the control unit 180 can list the words for which the hyperlink is set up on one side. Accordingly, when the user selects any one of the listed word lists, the controller 180 can display not only the page with the selected word but also the information linked with the word.

The linked information may be displayed on one side of the screen by dividing the screen (331), and may be overlaid on the body of the electronic book (332). When the linked information is overlaid and displayed, transparency can be adjusted.

The e-book reader related to the mobile terminal of the present invention may further include the additional functions for improving the convenience of the user in addition to the functions described above.

For example, although not shown in the drawings, it is possible to change the background color or the background design of the cover or body of the electronic book while maintaining the contents of the contents of the electronic book. Also, the volume can be confirmed according to the tilting direction and tilt angle of the mobile terminal by using a gyro sensor or the like. You can also make phone calls, browse the Internet or send emails while viewing a catalog (eg, business name, phone number, email, etc.). In addition, color information can be extracted while reading an e-book such as a magazine, thereby providing information about color to users interested in color. You can also display distance and altitude information using a map in an e-book. That is, the length of dragging the destination point by the user can be converted to the actual distance and altitude using the accumulation degree of the e-book map.

Meanwhile, another additional function can provide current position information when displaying or reproducing an electronic book. For example, an ebook consisting of a total of 100 pages can indicate that it is currently displaying 44 pages, or an audio ebook with a total of 10 minutes can indicate that it is currently playing a five minute section. It is preferable that a scroll bar is displayed on the image or audio audio guidance is provided to notify the user of the progress of the audio / image book while watching / listening to the book using only audio books and images. Optionally, it is preferable to display page information on the image.

In addition, when the user ends the e-book reader function and then re-executes the e-book reader function, the user can automatically display the page displayed when the user ends the e-book reader function. For example, when the user reads the 44 pages of the electronic book 1 and then exits and then displays the electronic book 1 again, the controller 180 automatically moves to page 44 and displays the page. Similarly, if the audio e-book is reproduced after the 5-minute interval of the audio e-book is reproduced, the controller 180 can automatically move to the 5-minute interval of the audio e-book and reproduce the audio e-book. As described above, the function of automatically opening a page read at the end of an electronic book is called an automatic spread function, and the history of all e-books read by the user can be managed. Therefore, when the user re-reads an e-book that has been read once, the portion that was previously read and then ended is automatically expanded.

All of the above embodiments can be applied to all modes such as text mode, sound mode, and text & sound dual mode.
