Description

  The present invention relates to a portable information device, an electronic book, and an information storage medium used for them.

  In recent years, electronic books and portable information devices, which are publishing forms in which information such as characters, images, and voices are recorded on electronic media such as CD-ROMs and FDs and used like books, have been put into practical use.

  Such electronic books and portable information devices can overcome the physical limitations of paper books. Non-linear reading styles are also possible, and readers can enjoy reading from various perspectives.

  Furthermore, since it takes less money and hassle to publish, it is possible to realize the ideal image of publishing where everyone can publish easily or publish specialized things with limited subscribers. It becomes possible.

  By the way, storing map information in such an electronic book or portable information device is convenient because it can be carried with you when you go out or travel, and you can refer to the map image. Especially in e-books and portable information devices, unlike normal maps, it is possible to realize a wide range of functions such as free enlargement, reduction, and scrolling of necessary parts. Become. This is because electronic books and portable information devices can realize functions that are much more enriched than ordinary paper books in searching and using information.

  However, no matter how many functions can be realized, if the operation is complicated or difficult, such as troublesome operation, the treasure is lost. In particular, since an electronic book and a portable information device are small and conveniently formed for carrying, an input method and an operation method suitable for this are desired.

  The present invention has been made in view of the problems as described above. The object of the present invention is to rotate, enlarge, reduce, scroll, etc. a map image in a portable information device or an electronic book capable of displaying the map image. It is to provide an electronic book, a portable information device and an information storage medium used therefor that can realize the above functions with a user-friendly human interface.

  The present invention is a portable information device including a display unit capable of displaying a map image, the finger motion detection means for detecting a movement history of a finger brought into contact with the display unit on which the map image is displayed, and the movement of the finger Based on the history, operation content determination means for determining that at least one operation of rotation, enlargement, reduction and scrolling of the map image has been input, and rotation, enlargement, reduction of the map image displayed on the display unit based on the determination. And map image generation means for generating a map image subjected to at least one scroll operation.

  According to the present invention, the user can input at least one operation of rotation, enlargement, reduction, and scrolling of the map image displayed on the display unit based on a finger movement history.

The movement history of the finger in contact with the display unit is a concept including a temporal element, and is distinguished from an operation that does not include a temporal element as in the case of simply touching an input mark or the like with a finger.

  According to the present invention, various operations can be input based on the movement history of the finger, so that it is not necessary to provide hardware such as buttons and a keyboard on the housing, and a more compact portable information device can be provided. In addition, since an operation input mark display or the like is not required on the screen, effective use of a small screen suitable for carrying is promoted, and a screen display that is easier to view is possible.

  In addition, since it is difficult to input an execution instruction and execution contents at the same time with a single operation using a button or the like, a plurality of operations such as an operation for specifying execution contents and an operation for executing execution instructions are required, which is complicated. . However, since the present invention is input by the movement of the finger, it is possible to simultaneously specify the operation amount and the operation range by detecting the finger instruction range, the movement range, etc., and provide an easy-to-use human interface. Can do.

  According to the present invention, the operation content determination means determines at least one operation amount of a rotation amount, an enlargement amount, a reduction amount, and a scroll amount of the map image based on the movement history of the finger, and the map image generation means A map image obtained by performing at least one of rotation, enlargement, reduction, and scrolling on the map image displayed on the display unit based on the determined operation amount is generated.

  According to the present invention, the user can simultaneously input an operation amount as well as an instruction to execute at least one of rotation, enlargement, reduction, and scrolling of the map image displayed on the display unit according to a finger movement history. it can.

  The operation execution instruction means an instruction to execute any operation such as rotation, enlargement, reduction, scrolling, and the like. The operation amount is, for example, the rotation amount for a rotation operation, the enlargement amount for an enlargement operation, the reduction amount for a reduction operation, the scroll amount for a scroll operation, and the enlargement / reduction or rotation. This means specifying the range to be displayed by scrolling.

  According to the present invention, the operation amount of various operations can be input based on the movement history of the finger. Therefore, the user can input a desired operation amount by adjusting the finger operation according to his / her needs. .

  In addition, since it is difficult for a button or tag to give an execution instruction by specifying an arbitrary operation amount in one operation, a plurality of operations such as an operation amount specification and an execution instruction are required, which is complicated. However, since the present invention is input by the movement of the finger, it is possible to simultaneously specify the operation amount and the operation range by detecting the finger instruction range, the movement range, etc., and provide a simple and easy-to-use human interface can do.

  Further, in the present invention, when the finger motion detection unit detects an operation of moving two fingers that are in contact with the display unit on which the map image is displayed, the operation content determination unit performs the map image enlargement operation. And the map image generating means generates an enlarged map image.

  The operation of moving the two fingers in contact with the display unit on which the map image is displayed is an operation that gives an image of the enlargement of the map image, and the user can accept the operation as an enlargement operation without a sense of incongruity. In addition, it is possible to give an execution instruction that designates enlargement contents such as an enlargement range and an enlargement amount, etc., by a single action, depending on the action position and the action amount of the finger.

  Therefore, according to the present invention, it is possible to provide a portable information device capable of a user-friendly enlargement operation.

  Note that the map image may be enlarged at a constant rate by one operation, or may be enlarged at a rate corresponding to the movement distance of the finger. When enlarging at a rate corresponding to the movement distance of the finger, the user can perform the operation with a single execution instruction specifying the enlargement amount, and an easy-to-use interface can be provided.

  Moreover, it is preferable that the range of the map image displayed on the display unit as a result of the enlargement is a range including the map image at the position where the finger is in contact before the enlargement. In this way, the user can execute an execution instruction designating the expansion range in one operation, and can provide an easy-to-use interface.

  The mode of enlarging the map image is not limited to simply reducing the scale. For example, before the enlargement, the map portion is mainly a map image mainly of information such as topography and city position. This includes the case where the map is expanded to become a detailed map of a city based mainly on information such as buildings and roads.

  Further, in the present invention, when the finger motion detection unit detects an operation of bringing two fingers brought into contact with the display unit on which the map image is displayed, the operation content determination unit performs the map image reduction operation. And the map image generating means generates a reduced map image.

  The operation of bringing two fingers brought into contact with the display unit on which the map image is displayed is an operation that makes a reduction in the map image appear, and the user can accept the operation as a reduction operation without a sense of incongruity. In addition, it is possible to give an execution instruction specifying a reduction content such as a reduction range or a reduction amount by a single operation according to the movement position and movement amount of the finger.

  Therefore, according to the present invention, it is possible to provide a portable information device capable of a user-friendly reduction operation.

  The map image may be reduced at a constant rate by one operation, or may be reduced at a rate corresponding to the movement distance of the finger. When reduction is performed at a rate corresponding to the movement distance of the finger, the user can perform a single operation with an execution instruction specifying the reduction amount, and an easy-to-use interface can be provided.

  Moreover, it is preferable that the range of the map image displayed on the display unit as a result of the reduction is a range including the map image at the position where the finger is in contact before the enlargement. In this way, the user can execute an execution instruction designating a reduction range in one operation, and an easy-to-use interface can be provided.

  Also, the mode of reducing the map image is not only when the scale is simply increased, but, for example, before the enlargement, it is reduced from a town map-like map image mainly composed of information such as buildings and roads. This includes cases where the map image is mainly based on information such as topography and city position.

  According to the present invention, the finger motion detection means detects an operation of rotating another finger that is in contact with the display unit with one finger that is in contact with the display unit on which the map image is displayed as an axis. In this case, the operation content determination unit determines that a map image rotation operation has been input, and the map image generation unit generates a rotated map image.

The operation of rotating the other finger that is in contact with the display unit around the one finger that is in contact with the display unit on which the map image is displayed is similar to the operation when the compass is used. For this reason, it is possible to imagine the rotation of the map image, and the user can accept the operation as a rotation operation without a sense of incongruity. In addition, it is possible to give an execution instruction specifying the rotation contents such as the rotation range and the rotation amount in one operation by the operation position and operation amount of the finger.

  Therefore, according to the present invention, it is possible to provide a portable information device capable of a user-friendly rotation operation.

  Further, when it is desired to match the orientation that the user is currently facing with the orientation on the screen, the map itself is rotated in the case of an actual map. However, in the case of the portable information device of the present invention, the same effect can be obtained by rotating the displayed map image. For this reason, the user can see the map image rotated in a desired direction with a simple operation, and can provide the provided portable information device that is easier to use than the actual map.

  Note that the map image may be rotated at a constant rate by one operation, or may be rotated at a rate corresponding to the movement distance of the finger. When the user rotates at a rate corresponding to the movement distance of the finger, the user can execute an execution instruction specifying the rotation amount in one operation, and an easy-to-use interface can be provided.

  Moreover, it is preferable that the range of the map image displayed on the display unit as a result of the rotation is a range including the map image at the position where the finger is in contact before the rotation. In this way, the user can perform an execution instruction specifying the rotation range in one operation, and can provide an easy-to-use interface.

  The present invention is the portable information device described above, which is used as an electronic book.

2.2 Map Image Manipulation Processing by Finger Movement Next, a specific example of map image manipulation by finger movement in the electronic book of the present embodiment will be described.

  FIG. 3 is a diagram showing an example of a screen displayed when travel information software is set. The center of the screen is mainly used as an information display area, and the end area of the screen is mainly used as a search tag area or a toolbar display area. In the information display area, the contents described in one page of the book are displayed as image information. Search tags 210 to 230 are displayed in the search tag area. In addition, images 240 and 242 simulating “book thickness” are displayed on the left and right edges of the display area.

2.2.1 Map Enlargement Operation When the user touches the “map” 220 field of the search tag with the finger 250, the entire map 260 of “India” is displayed on the screen (see FIG. 4). To obtain information about “Bombay”, place the thumb and index finger around “Bombay” on the screen with the thumb and index finger close as shown in FIG. 6B, and move the thumb and index finger away. An action of moving in the direction (map enlargement gesture) is performed (see FIG. 5). In this way, a map image enlarged according to the movement history of the thumb and index finger is displayed. That is, the greater the degree of separation between the thumb and index finger, the smaller the scale and the more detailed the map is displayed.

  At this time, the map on the screen may be enlarged corresponding to the operation of moving the thumb and index finger away in real time. Further, after the final enlargement amount is determined when the finger stops moving, a map image enlarged according to the enlargement amount may be displayed.

  Further, as shown in FIG. 7, a case where the thumb is fixed and only the index finger is moved away from the thumb may be included in the map enlargement gesture.

  As a result of referring to the enlarged map, when it is desired to obtain a more detailed map image, a more detailed map image can be obtained by repeating the map enlargement gesture. In the present embodiment, when the city map is enlarged to some extent, a detailed map of the city such as a town map is displayed.

2.2.2 Map scrolling operation As shown in Fig. 8, if you place your finger on the screen and move it in the desired direction while pressing your finger on the screen (map scroll gesture), The map is moved and displayed by the distance moved.

2.2.3 Map Reduction Operation In addition, when it is desired to reduce the map, for example, when it is desired to view a map image of a larger scale or to display a wide range of information on the screen, the map is first displayed as shown in FIG. As shown in FIG. 9, the thumb and index finger are separated from each other and placed on a map displayed on the screen, and the thumb and index finger are moved toward each other as shown in FIG. 9 (map reduction gesture). In this way, a map image reduced according to the movement history of the thumb and index finger is displayed. That is, the greater the degree of separation between the thumb and index finger, the smaller the scale and the more detailed the map is displayed.

  At this time, the map on the screen may be reduced in real time with the operation of bringing the thumb and index finger close together. In addition, after the final reduction amount is determined when the movement of the finger stops, a map image reduced according to the reduction amount may be displayed.

  In contrast to FIG. 7, the map reduction gesture may also include a case where the thumb is fixed and only the index finger is moved closer to the thumb.

  As a result of referring to the reduced map, if it is desired to obtain a map image of a wider range, a map image of a wider range can be obtained by repeating the map reduction gesture. In the present embodiment, if the city map is reduced to some extent, the detailed map of the city such as the town map is changed to the normal map display and displayed.

2.2.4 Map rotation operation If you want to change the orientation of the displayed map image without changing the scale, first place your thumb and index finger apart as shown in Fig. 6 (A). Place on the map displayed on the screen, fix either one of the thumb or index finger, and rotate the other finger like a compass around the fixed finger (map rotation) Gesture) (see FIG. 10). In this way, a map image rotated according to the movement history of the thumb and index finger is displayed.

  As shown in FIG. 11, when one of the fingers is fixed to the point O and the other finger is rotated from the point A to the point B, it is rotated from A to B by the rotation angle Θ. A map image rotated in the direction 370 is displayed.

  At this time, the map on the screen may be rotated in real time with the rotation of either one of the fingers. Further, after the final rotation amount is determined when the finger stops moving, a map image reduced according to the rotation amount may be displayed.

  The finger movement is not limited to the case of performing with the thumb and the index finger, and may be performed with, for example, the thumb and the middle finger or a combination of other fingers.

2.3 Search Process Next, a specific example of the search process by the finger movement in the electronic book of the present embodiment will be described.

2.3.1 Normal Search Operation For example, when the user wants to obtain information on a hotel in “South India”, there is a method as shown in FIG. That is, first select the tag "South India", display the first page with information on "South India", then select the tag for accommodation, and the head with information on "South India accommodation" This is a method of displaying a page. When the user wants to obtain various information about “South India”, the user wants to display the first page on which information on “South India” is posted, and then searches for various information on “South India”. It is effective for etc.

2.3.2 Search operation with AND condition However, if the user needs only “South India Accommodation” information, the information of “South India Accommodation” was posted directly in one operation. The first page is preferably displayed. Therefore, in this embodiment, as shown in FIG. 13A, when the user touches the tag “South India” with the finger of the left hand and the tag “stay” with the finger of the right hand, for example, It is configured to display the first page with information on “South India” directly.

  When the information on “South India” is spread over a plurality of pages, the information described in the following pages can be read by performing page turning input as shown in FIG.

2.4 Page Turning, Bookmark Processing, etc. Next, a specific example of turning pages with the electronic book of this embodiment will be described.

2.4.1 Page turning input operation In the electronic book of the present embodiment, various operations are input as finger movements on the screen, so that there are almost no buttons for operation input on the housing. Further, the screen on which the contents of the book are displayed is characterized in that there are almost no operation input marks on the screen (see FIG. 3).

  In the present embodiment, by setting the travel information software in the electronic book, the user can use the same as in the case of referring to the travel guidebook, and is similar to the actual book page on the screen as shown in FIG. You can refer to the contents of

  When the user wants to refer to the next page, if the user traces the information display area on the screen with the index finger from the left to the right as when turning the page of a paper book, the page appears as shown in FIG. The display screen is updated to the contents of the next page with an image that turns over.

  At this time, it is necessary for the user to move his / her finger in the horizontal direction so as to rub with a certain degree of strength by sliding the index finger or the like on the screen. In this embodiment, in order to distinguish the page turning input from other inputs, when the finger is touching the screen at a predetermined area or more and a predetermined pressure value or more and moving in the horizontal direction, This is because it is determined that turning has been input.

  Note that the page turning direction and page up / down differ depending on the vertical writing or horizontal writing as in the actual book. Therefore, in the case of a vertically written book, the page advances from the right to the left. Therefore, when the finger is moved as shown in FIG. 14, the next page is turned, but in the case of horizontal writing, the previous page is turned. On the other hand, in the case of a vertically written book, the previous page is turned when tracing with the index finger from the right to the left, as opposed to FIG. 14, but in the case of horizontal writing, the next page is turned.

  In this way, the user can input the page turning in the same way as when handling a normal book, so that it is possible to provide a human interface that is easy to learn and easy to use.

  In addition, when inputting a page turning, an image in the middle of turning the page according to the movement of the finger may be displayed as shown in FIG. 14, but it may be configured to switch directly to the previous page screen or the next page screen.

  In addition, an image sound that can be associated with the sound of turning the page such as “para” corresponding to the page turning may be output.

2.4.2 Continuous page turning input operation Also, as shown in FIG. 15, an image imitating “book thickness” (hereinafter referred to as “book thickness”) 24
If the user keeps touching 0 and 242 for a predetermined time or more, the pages are flipped continuously. At this time, the page turning speed can be changed by changing the strength with which the user touches. That is, the user can increase the speed at which the page is turned by touching more strongly. Also, by reducing the strength of touching, you can slow down the page turning speed. When the user finds the page he / she wants to read, the user can release the “book thickness” to stop the continuous page turning and position the display screen on the page.

  As in the case of the page turning described above, the raising / lowering of the page differs depending on the vertical writing or the horizontal writing. Therefore, in the case of a vertically written book, if the thickness of the leftmost book is continuously touched as shown in FIG. 15, the page turns continuously in the direction of the next page, but in the case of horizontal writing, the page continues in the direction of the previous page. Turn over. On the other hand, in the case of vertical writing, conversely to FIG. 15, if you keep touching the thickness of the rightmost book, the page will turn continuously in the previous page direction, but in horizontal writing, the page will continue in the next page direction. Turn over.

  In this way, the user can input the page turning in the same way as when handling a normal book, so that it is possible to provide a human interface that is easy to learn and easy to use.

  In addition, during continuous page turning input, an image in the middle of turning the page according to the movement of the finger may be displayed as shown in FIG. 15, but it may be configured to switch directly to the previous page screen or the next page screen every predetermined time. Good.

  In addition, an image sound that can be associated with a sound that the page turns, such as “para-para-pala”, may be output corresponding to the page turning.

2.4.3 Bookmark insertion and reference operation Next, the bookmark function of this embodiment will be described. In this embodiment, it is possible to attach a bookmark to a page to be referred to again so that a bookmark is inserted at a position to be referred to again during normal reading.

  As shown in FIG. 16, a bookmark can be inserted into the page by dragging the arrow portion 260 and tracing it with the finger to the bottom of the screen. That is, after the above operation, the bookmark mark 270 is displayed on the screen as shown in FIG.

  When the user is referring to another page, a bookmark 270 is displayed at the lower end of the screen as shown in FIG.

  When the user wants to refer to the page with the bookmark, the user touches the bookmark 270 displayed at the bottom of the screen with a finger as shown in FIG. 18B, as shown in FIG. 18C. Then, the screen switches to a page with a bookmark.

  In addition, although it demonstrated taking the case where only one bookmark was pinched | interposed, it is not restricted to this. For example, when bookmarks are to be attached to a plurality of pages, bookmark marks of a plurality of colors may be displayed.

2.5 Example of Use of Today's Folder Next, a specific example of use of today's folder of the present embodiment will be described.

In FIG. 3, when the input icon 280 is touched with a finger, a toolbar composed of various operation icons (282, 284, 286, 288) is displayed at the bottom of the screen as shown in FIG.

  Reference numeral 282 denotes an icon to be touched when shifting to a mode for inputting various settings of the electronic book. Reference numeral 284 denotes an icon to be touched when shifting to a mode for shooting a moving image or a still image with a camera which is an accessory of the electronic book. Reference numeral 286 denotes an icon to be touched when shifting to a mode in which characters, figures, and the like are input by using a pen that is an accessory part of the electronic book. Reference numeral 288 denotes an icon that is touched when the input data or information specified on the screen is stored in the today's folder, or when it is desired to refer to the contents of the today's folder. This today's folder is automatically created every day, and its usage is like a warehouse where data created in daily use scenes is always kept. Hereinafter, various usage examples of today's folder will be described.

2.5.1 Example of Floating and Stored Information Stored in Electronic Book An example of floating and storing information stored in an electronic book will be described with reference to FIGS. For example, if you want to get information on “North India”, touch the index of “North India” to open the page and read it. Among them, the word “Tajma Heil” is displayed in red, so touch it (see FIG. 20A). Then, it is configured to automatically jump to the “Tajma Hail” page.

  For example, if you read about “Tajma Heil” in a regular paper book and want to copy this part and carry it with you, you can perform the following operations on this electronic book.

  That is, the user encircles the area in which the information that the user wants to cut is written with the index finger, and moves the finger away from the screen (see arrow 410 in FIG. 20B). Then, the enclosed portion is displayed as if it was raised on the screen (see 420 in FIG. 21). This is called floating.

  Then, press the floating part with your finger, move to the icon 288 of today's folder by dragging and dropping, and release your finger there (hereinafter referred to as “drag and drop to today's folder”) ) And (see FIG. 22), the floating part is stored in the folder of today. In this way, in this electronic book, if the content to be cut is designated with a finger and dragged and dropped into the today's folder, the content designated on the screen can be stored in the today's folder.

  Note that the area to be floated is not limited to an area that can be enclosed by a closed curve or a polygon, but may be an area that is specified by an edge of the screen and a part enclosed by a finger. For example, as shown in FIG. 42A, when a trace is drawn with a finger like 840 and the screen is traced, a portion 852 (shaded area) surrounded by the trace 840 and the edge line 850 at the end of the screen is floated. You may do it.

  Further, as shown in FIG. 42B, two points P1 and P2 on the screen are designated with a finger, and a rectangular region 854 (hatched region) having a line segment connecting the two points as a diagonal is floated. It may be.

  Further, as shown in FIG. 42 (C), three points P3, P4, and P5 on the screen are designated with a finger, and a circular region 856 (hatched region) having the three points on the circumference is floated. You may do it.

2.5.2 Example of storing still images and moving images Next, an example of storing video captured by a camera in today's folder will be described with reference to FIGS.

  For example, when the user wants to share the contents of the timetable during the trip, if the electronic book is used, the camera lens 520 provided in the electronic book body is pulled out as shown in FIG. The timetable 510 can be photographed and the photographing data can be stored in an electronic book.

  That is, when the user pulls out the toolbar of the electronic book and touches the camera icon 284 with his / her finger, the shooting mode is set, and a camera shooting operation display screen as shown in FIG. 23 is displayed. The user touches the screen switches 550 and 540 displayed on the finder screen 530 arranged largely on the left side of the screen with a finger to take a video or a still image. You can choose.

  For example, when the user touches the still image screen switch 540, the display of the shooting execution switch 560 changes to “shutter”. When the user points the camera lens toward the timetable 510, a timetable image captured by the camera lens 520 is displayed on the viewfinder screen 530. When the user touches the “shutter” button 560 with a finger, the image data that has been taken is automatically stored in the folder file together with the shooting date and time.

  The folder file is a file for storing information to be put in “today's folder”. The stored information is managed by date and time, and is formed so as to be readable in date units.

  Further, for example, when the user wants to shoot a moving image, when the moving image switch 550 is touched, the display of the shooting execution switch 560 changes to “waiting for recording”. When the user touches the “recording standby” button, shooting of a moving image is started.

  Note that the camera lens 520 of the electronic book is a wireless type that can be removed from the electronic book main body 522 as shown in FIG. When the user presses the shooting execution switch 560 displayed as “Recording standby”, the display is switched to “Recording”. If the user wants to interrupt shooting, touching the “shooting” button with his / her finger stops shooting and the display switches to “waiting for shooting”. The captured image is automatically stored in the folder file together with the shooting date and time.

2.5.3 Example of storing memos Next, an example of storing user memos will be described with reference to FIGS. 26 and 27. FIG.

  When the user pulls out the toolbar at the bottom of the screen and touches the “memo” icon 286 with a finger, a memo input screen 600 as shown in FIG. 26 is displayed. When the user inputs characters or the like on this screen with the pen 610 attached to the electronic book, the image data is recorded as it is. After the writing, as shown in FIG. 27, when the memo input screen is dragged and dropped to today's folder, the contents described in the memo input screen 600 can be stored in the folder file together with the storage date and time.

2.5.4 Reference processing of today's folder When the user pulls out the toolbar at the bottom of the screen and touches the “today's folder” icon 288 with his / her finger, the today's folder screen 700 of that day as shown in FIG. 28 is displayed. Is displayed. The data stored in today's folder on that day is displayed as icons (710, 720, 730, 740). In this electronic book, the data content stored by the user is converted into an icon as a reduced image as it is, so that the user can easily recall the contents of the data. Furthermore, since the time when the data is stored is displayed below the icon, it can be easily used as a user's action record, and is convenient for organizing the data later.

  When the user touches iconified data 710, 720, 730, 740 with a finger and drags and drops it to the “view contents” portion 750, the contents are displayed on the screen. Similarly, the contents can be automatically deleted by putting them in the trash box portion 780 marked “Discard”.

  Touching the portion 760 labeled “Previous Day” displays the “Today's Folder Screen” on the previous day, and touching the portion 770 labeled “Next Day” displays the “Today's Folder Screen” on the next day. Is displayed. The user can go back to the previous folder screen or return to the current folder screen by touching the “previous day” and “next day” portions.

  Also, as shown in FIG. 29, when the icons of related data are moved with a finger so as to touch, the data in contact are grouped. Therefore, it is convenient for data organization.

FIG. 30 is a diagram for explaining an example of utilization of today's folder.
For example, assume that a user carries this electronic book on a trip for about one month and stores various data in today's folder during the trip. When the user opens the electronic book, 30 today's folders are stored (see FIG. 30A).

  The user writes the data of today's folder stored in the electronic book 800 to another computer 810 connected to the Internet, and sends the data to the travel data collection company 820 using the Internet (see FIG. 30B).

  The travel data collection company 820 edits the collected data and supplies the latest travel data to the travel software publishing company 830. The travel software publishing company 830 releases travel software upgraded based on the latest data.

  If the electronic publishing industry develops in this way, it will be able to supply digital software that reflects the latest data. In addition, because it does not require money or hassle, publishing an ideal image of publishing that everyone can publish easily or can publish specialized things with limited subscribers.

2.7 Operation Example of the Present Embodiment FIGS. 33 to 41 are flowcharts showing an operation example of the electronic book of the present embodiment.

  In the electronic book of the present embodiment, when there is an input such as finger movement, pen input, photographing, etc., the processing content is determined as follows (step S10 in FIG. 33). If it is the current shooting mode, shooting processing is performed (steps S20 and S30). Note that the normal input mode is selected, and when the camera icon on the tool bar is touched, the shooting mode is entered. When an input is detected in the shooting mode, the shooting process described with reference to FIGS. 23 to 25 is performed.

  For example, when it is detected that the user has pressed an operation button on the screen, processing corresponding to the button, for example, when a “moving image” or “still image” button is touched, selection processing of moving image and still image When the “Shutter” button is touched, a still image is shot, and the captured image data is stored in a folder file with the shooting date and time. When the “Recording standby” button is touched, , The process of starting the video recording, the process of ending the video recording when the “Recording” button is touched, and storing the captured image data in the folder file with the shooting date and time, etc. .

If it is the current memo input mode, a memo input process is performed (steps S40 and S50). Note that the normal input mode is selected, and when the memo icon on the toolbar is touched, the mode shifts to the memo input mode. When an input is detected in the memo input mode, the memo input process described with reference to FIGS. 26 to 27 is performed.

  For example, when it is detected that the user has entered a character or the like with a pen on the screen, the input content is displayed in real time, and the input content is stored in the work area as image data. When the input content is dragged and dropped, a process of storing the image data stored in the work area in a folder file with the date and time of storage is performed.

  If it is the current folder reference mode, folder reference processing is performed (steps S52 and S54). Normally, the mode is the normal input mode, and when today's folder icon on the toolbar is touched, the mode shifts to the folder reference mode. When an input is detected in the folder reference mode, the folder reference process described with reference to FIGS. 28 to 29 is performed.

  For example, when it is detected that the user has touched an icon on the screen and dragged and dropped it to the “view contents” portion, processing for displaying the data contents on the screen is performed. Similarly, when it is detected that the object has been put in the trash box marked “discard”, a process of deleting the data is performed. When it is detected that the part labeled “Previous Day” is touched, the process of displaying the “Today's Folder Screen” of the previous day is performed, and the part labeled “Next Day” is touched. The next day “Today's folder screen” is displayed on the next day.

  In the normal input mode, when a finger touches the touch panel, the following processing is performed (see step S60 in FIG. 33 and FIG. 34).

  When there is contact with the icon on the tool bar, various icon processing (see FIG. 41) is performed (steps S70 and S80 in FIG. 34).

  In the case of contact with various input marks such as “search tag”, “book thickness”, “bookmark”, and “bookmark insertion arrow”, input mark operation processing (see FIG. 36) is performed (step 36). S90, S100).

  If there is a second contact with the touch panel, and if a map image is displayed, map operation processing is performed (steps S110, S120, and S130).

  If there is no contact at the second point, it is detected whether or not the contact point is moving, and if it is moving, the processing content that is instructed by the contact area and the contact pressure is determined ( Steps S140 and S150).

  If the contact area and the contact pressure are equal to or greater than the predetermined values, scroll processing is performed if the displayed image is a map image, and page turning processing is performed if the displayed image is a normal book page image (step S160). , S180).

  When the contact area and the contact pressure are not equal to or greater than the predetermined value, the following processing is performed (see FIG. 35). If there is information surrounded by a finger when not dragging and dropping to “today's folder”, floating processing of the information surrounded by the finger is performed (steps S910, S960, and S970).

  In the case of drag and drop to “today's folder”, if it is a memo content, the memo content is stored as image data in a folder file with the storage date and time (steps S920 and S930).

  If it is floating data, the storage date is added to the floating data and stored in a folder file (steps S940 and S950).

  FIG. 36 is a flowchart for explaining detailed processing contents of the processing (step S100 in FIG. 34) when the touch to the input mark is detected.

  When the user's finger is in contact with the search tag, search processing is performed (steps S210 and S220).

  If the user's finger is in contact with the bookmark insertion arrow mark, bookmark insertion processing is performed (steps S230 and S240).

  If the user's finger is in contact with the bookmark mark, bookmark insertion location reference processing is performed (steps S250 and S260).

  The contact pressure of the user's finger is detected, and if it is not equal to or higher than the predetermined pressure value, continuous page turning is stopped (steps S610, S620, S630).

  If the pressure value is equal to or higher than the predetermined pressure value, continuous page turning is performed as follows.

  That is, if the contact position of the user's finger is the thickness of the rightmost book on the screen, if the displayed book is a vertically written book, the page is continuously turned in the previous page direction, and the horizontally written book In this case, page turning is continuously performed in the next page direction (steps S640, S650, S660, S670).

  If the contact position of the user's finger is the thickness of the book at the left end of the screen, if the displayed book is a vertically written book, the page will be turned continuously in the direction of the next page, and the horizontally written book will be displayed. In this case, page turning is continuously performed in the previous page direction (steps S640, S680, S690, and S700).

  FIG. 41 is a flowchart for explaining detailed processing contents of various icon processing (step S80 in FIG. 34).

  If the touch is on the camera icon, a camera shooting operation screen as shown in FIG. 23 is displayed and the mode is shifted to the shooting mode. (Steps S810 and S820). Hereinafter, when there is an input during the shooting mode, the shooting process of step S30 in FIG. 33 is executed.

  If the touch is on the memo icon, a memo input screen as shown in FIG. 26 is displayed and the memo input mode is entered. (Steps S830 and S840). Hereinafter, when there is an input during the memo input mode, the memo input process of step S50 of FIG. 33 is executed.

  If the touch is on the today's folder icon, the today's folder screen as shown in FIG. 28 is displayed and the mode shifts to the folder reference mode. (Steps S850 and S860). When there is an input during the folder reference mode, the folder reference process in step S54 in FIG. 33 is executed.

2.8 Other Various Embodiments The present invention is not limited to this embodiment, and various modifications can be made within the scope of the gist of the present invention.

  In this embodiment, the case where operation input is performed using the thumb and index finger has been described as an example, but the present invention is not limited to this. For example, the thumb and middle finger may be used, or other combinations of fingers may be used.

  In this embodiment, the case of an electronic book has been described as an example, so that the first page in which search information that is the logical product of search items is displayed is displayed. However, in the case of a portable information terminal other than an electronic book, There may be no concept. Therefore, information units may be displayed regardless of the page.

  In the present embodiment, the case where two search items are simultaneously touched with a finger and search information that is the logical product of the two items is output has been described as an example. However, the present invention is not limited to this. For example, three or more search items may be simultaneously touched with a finger, and search information that is a logical product of the three or more items may be output.

  Further, the search information is not limited to the case of touching with a finger at the same time, and search information that is a logical product may be output when touching with a finger within a predetermined time.

  In addition, when there is no information having a logical product relationship with a search condition corresponding to a plurality of search items touched with a finger at the same time or within a predetermined time, at least one of logical sum and a combination of logical sum and logical product is determined. You may comprise so that the means to output the information which it has to a display part may further be included.

  For example, when the tags “South India”, “Accommodation” and “Meals” are touched at the same time, the South India accommodation information and South India meal information may be output.

In particular, when the information is displayed regardless of the page, it is effective to take such a configuration.
For example, if an electronic book or a portable information terminal that stores phone numbers can be searched and output by phone number, specifying multiple phone number search items in the table of contents automatically performs an OR operation. And the case of listing telephone numbers having a logical product relationship. That is, for example, when an item in a common set of “A hospital in A district” such as “A district” and “hospital” is designated, information in a logical product relationship is retrieved and output, When items that are not related to a common set such as “A district” and “B district” or “hospital” and “library” are designated, information having a logical sum is retrieved and output.
