Description

The present invention relates to an electronic device, a display method, and a display program.

Electronic devices such as electronic dictionaries store various types of content, and can output content arbitrarily selected by a user's operation. Various types of content include, for example, dictionaries, encyclopedias, study reference books, problem sets, literary works, and explanatory books. Generally, content data is classified according to a hierarchical structure. For example, content data is classified into each hierarchy such as part, chapter, section, paragraph, and body.

Hierarchical search (also called table of contents search or classification search) is a method of searching for content to be displayed from content that has a hierarchical structure. In hierarchical search, by selecting any of the categories (items, etc.) in the upper layer, the contents of the lower layers (for example, an item list) included in the selected category are displayed. By repeating the operation of selecting any classification in each hierarchy, the contents of any hierarchy can be displayed.

JP2014-63228A

Conventionally, when performing a hierarchical search for content having a hierarchical structure, it has been difficult to understand the volume of content data in the hierarchy to be displayed. In other words, it is difficult to know how much volume of data is included in the lower layers of the content in the layer to be displayed.

For example, when using the content of a study reference book, the user selects items one by one through hierarchical search and proceeds with learning while changing the contents of the displayed hierarchy. In such cases, with conventional electronic devices, it is not possible to grasp the amount of learning content, including the lower levels included in the item to be displayed, from the item list.

Therefore, even if you set up a study plan of "one chapter a day," for example, there may be large differences in the amount of learning content data for each chapter (including sections, paragraphs, and main text), so you can make steady progress in your studies. A situation may arise where this cannot be done.

Additionally, in the past, it was possible to visually know the volume of a group by grouping multiple contents, calculating the number of pages in the group, and displaying a book image that reflected the thickness according to the number of pages. It is considered to do so (see Patent Document 1). However, since the book image is displayed separately from the display of the content, it is not possible to know the volume of the content to be displayed, and it is also not possible to know the volume of each content.

The present invention has been made in consideration of the above-mentioned problems, and it is an object of the present invention to provide an electronic device, a display method, and a display program that can easily grasp the volume of data included in a hierarchy to be displayed. With the goal.

In order to solve the above problems, an electronic device according to an embodiment of the present invention is an electronic device including a control section, wherein the control section has a hierarchical structure and stores content data in which items are set in the hierarchy. First content data included in any display hierarchy of the included content , and other first content data that is different from the first content data and is included in any of the display hierarchy. A hierarchical image of a first display format displayed in a list format in a predetermined direction, and each of the first content data included in the display hierarchy and the lower order of each of the first content data with respect to the data amount of the entire content. The hierarchical image of the second display form, which is set according to the ratio of the total data amount of the data amount of the second content data in the layer, is displayed adjacently.

According to the present invention, it is possible to provide an electronic device, a display method, and a display program that can easily grasp the volume of data included in a hierarchy to be displayed.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a functional block diagram showing the configuration of an electronic circuit of an electronic device according to an embodiment of the present invention.

In this embodiment, an example in which the electronic device is configured as, for example, an electronic dictionary 10 will be described. Note that the electronic device can be realized by various electronic devices such as a personal computer, a smartphone, and a tablet PC in addition to the electronic dictionary 10.

The electronic dictionary 10 is a device that can read data from dictionaries and dictionaries by inputting headwords (headword search), selecting items (hierarchical search), etc., and displaying and reproducing various information. It is. The dictionary data stored in the electronic dictionary 10 includes information regarding at least one word meaning corresponding to each of a plurality of headwords. Information regarding word meaning includes text information. The dictionary data includes, for example, English-based dictionaries, Japanese-based dictionaries, encyclopedias, and the like. Examples of English-based dictionaries include a Japanese-English dictionary, an English-Japanese dictionary, an English-English dictionary, and an English thesaurus, each of which may include a plurality of different dictionaries. Similarly, Japanese dictionaries include a Japanese dictionary, a thesaurus, an antonym dictionary, an old language dictionary, and the like, each of which may contain a plurality of different dictionaries.

Further, the electronic dictionary 10 records content data of various contents such as study reference books, problem collections, literary works, and explanatory manuals. Various types of content have a hierarchical structure, and content data is classified by hierarchy such as, for example, part, chapter, section, paragraph, and body. Content data is displayed by selecting items (classifications) for each hierarchy (hierarchical search) by a user's operation.

The electronic dictionary 10 has a computer configuration in which a program recorded on various recording media or a transmitted program is read and the operation is controlled by the read program, and its electronic circuit includes a CPU ( central processing unit) 11.

The CPU 11 functions as a control unit that controls the electronic dictionary 10 as a whole. The CPU 11 uses a control program stored in advance in the memory 12, a control program read into the memory 12 from a recording medium 13 such as a ROM card via a recording medium reading unit 14, or a server via a network N including the Internet. The operation of each part of the circuit is controlled according to a control program downloaded from 20 via communication unit 15 and read into memory 12.

The control program stored in the memory 12 includes input signals corresponding to user operations from the key input unit 16, input signals corresponding to user operations from the touch panel 17, or communication with a server 20 on an externally connected network N. It is activated in response to a signal or a connection communication signal with a recording medium 13 such as EEPROM (registered trademark), RAM, ROM, etc. connected via the recording medium reading section 14 .

A memory 12, a recording medium reading section 14, a communication section 15, a key input section 16, a touch panel 17 as a display section, and the like are connected to the CPU 11.

The control programs stored in the memory 12 include a system program that controls the overall operation of the electronic dictionary 10, a communication program for data communication with the externally connected server 20 on the network N, and other electronic devices such as personal computers. is memorized. Furthermore, the memory 12 stores a dictionary control program 12a that executes a search function of searching and outputting information corresponding to input data from dictionary data or content data. Based on the dictionary control program 12a, the CPU 11 causes the touch panel 17 (display) to display information on the content data retrieved by the search function as well as a hierarchical image that allows the volume of the content data to be easily grasped. The hierarchical image is displayed, for example, in an item list format (hierarchical images in a first display format and a third display format, described later), or in a bar format (hierarchical images in a second display format, described later).

The memory 12 also stores dictionary data 12c, content data 12e, and the like.

The dictionary data 12c includes, for example, a database that collects a plurality of dictionaries/dictionaries such as an English-Japanese dictionary, a Japanese-English dictionary, an English-English dictionary, a Japanese dictionary, a thesaurus, an antonym dictionary, and an old word dictionary. The dictionary data 12c includes information such as text corresponding to each headword or item for each dictionary/dictionary.

The content data 12e is data of various contents such as study reference books, problem collections, literary works, and explanatory manuals, and includes data such as images (still images and videos), audio, and the like in addition to text. Content data is managed in a hierarchical structure, and each category (item) of content data in an upper hierarchy includes content data in a lower hierarchy. For example, there is content data for multiple "chapters" in the upper hierarchy, each chapter contains content data for multiple "sections" in the lower hierarchy, and each section further contains content data for multiple "sections" in the lower hierarchy. Contains the content data of the "paragraph". The structure of the hierarchy of each content differs depending on the content.

Note that the dictionary data 12c and the content data 12e may not be built into the main body of the electronic dictionary 10, but may be obtained from a database (for example, the server 20) that can be accessed through the network N, or may be obtained from a removable recording medium. 13 through the recording medium reading section 14.

FIG. 2 is a front view showing the external configuration of the electronic dictionary 10.

In the case of the electronic dictionary 10 in FIG. 2, a CPU 11, a memory 12, a recording medium reading section 14, and a communication section 15 are built in the lower part of the main body of the device, which is opened and closed, as well as a key input section 16 and a pen storage section 18a. , a touch panel 17 is provided on the upper stage side.

The key input section 16 includes a character input key 16a, a dictionary selection key 16b for selecting various dictionaries and various functions, an enter key 16c, a return key 16d, a cursor key (up/down/left/right keys) 16e, a power button, and others. It is equipped with various function keys.

The touch panel 17 is configured by combining a display such as an LCD (Liquid Crystal Display) and a touch pad (position input device), for example. The touch panel 17 displays, in addition to the constantly displayed button 17a, various menus and buttons corresponding to the execution of various functions, and various information such as text and images. In one embodiment, the display unit does not need to have a function as a touch panel. For example, an LCD may be used as the display section instead of the touch panel 17.

The electronic dictionary 10 can input instructions by the user in response to the user's operation on the key input unit 16 or touch operation on the menu or button displayed on the touch panel 17 (using the tip of the pen 18 or the tip of the finger). can.

In the electronic dictionary 10 configured as described above, the CPU 11 controls the operation of each part of the circuit according to instructions written in the dictionary control program 12a, and the software and hardware work together to perform the following operations. Achieve the functionality described in the description.

FIG. 3 is a diagram showing an example of a hierarchical structure of content in this embodiment. Figure 3 shows, for example, the hierarchical structure of the content of the "Japanese History Glossary", and shows that there are 2nd, 3rd, and 4th tiers in order from the 1st tier at the top. .

For example, the first level has multiple "parts", and for example, the lower level (second level) of one part "Part 1 Primitive/Ancient 1" has multiple "chapters" (Chapters 1 to 1). Chapter 3) is included. Similarly, it is shown that a lower hierarchy (third hierarchy) of one "chapter" includes a plurality of "sections" (detailed illustration is omitted).

Next, the operation of the electronic dictionary 10 in this embodiment will be explained.

(First embodiment)
FIG. 4 is a flowchart showing dictionary search processing in the first embodiment.

When the user inputs an instruction to select any content by touching a menu or button displayed on the touch panel 17 or by operating the key input unit 16, the CPU 11 selects the content data of the selected content. 12e (step A1). Further, the CPU 11 causes the touch panel 17 to display a search screen for the selected content.

FIG. 5 is a diagram showing an example of the content search screen D1 in the first embodiment.

The search screen shown in FIG. 5 targets the content "Japanese History Glossary" and includes a character input area D11 for inputting a character string for headword search, and a hierarchical search for instructing a hierarchical search. A button D12 is provided.

Here, when a character is input into the character input area D11 by operating the character input key 16a or the like, a search by headword search is instructed (step A2, headword search). In this case, the CPU 11 searches the dictionary data 12c using the characters input in the character input area D11 as headwords (step A4), extracts headwords containing the input characters at the beginning, and displays them as a headword list on the touch panel. 17. When characters are continuously input into the character input area D11 (step A6, No → step A3, Yes), the CPU 11 similarly extracts a headword that includes the input character at the beginning, and converts it into a headword. The list is displayed on the touch panel 17 (steps A3 to A6).

When the CPU 11 selects a headword from the headword list by operating the cursor key 16e and enter key 16c or using the pen 18 (step A6, Yes), the CPU 11 selects content data corresponding to the selected headword. is displayed on the touch panel 17.

On the other hand, when the hierarchical search button D12 is selected (step A2, hierarchical search), the CPU 11 calculates the data amount of content data including the lower hierarchy for each classification of the display hierarchy, and the content data of the display hierarchy (first The total amount of the display layer, which is the sum of the amount of data (content data) and the amount of data for each category, and the content data (first content data) of the display layer are obtained (step A8). Here, the top layer (first layer) is the display layer, and for each classification in the top layer, the amount of content data (second content data) in the lower layers up to the lowest layer included in the classification is calculated. and obtains the total amount of display hierarchy (the data amount of the entire content when the display hierarchy is the highest layer), which is the sum of the data amount of the content data of the highest layer and the data amount of lower layers for each classification.

For example, in the content hierarchy shown in Figure 3, there are four content data (first content data) in the display hierarchy: "Part 1 Primitive/Ancient 1" to "Part 4 Modern/Contemporary" in the first hierarchy. Get an item list with items. Furthermore, the amount of content data (second content data) in the lower hierarchy is acquired for each of the four items (classifications) of "Part 1: Primitive/Ancient 1" to "Part 4: Modern/Contemporary." In other words, for the classification of "Part 1 Primitive/Ancient 1", the content data of the second layer "Chapter 1" to "Chapter 3" of the lower hierarchy included in "Part 1 Primitive/Ancient 1" Furthermore, the data amount of each content data is acquired for the third layer of the lower hierarchy included in each of "Chapter 1" to "Chapter 3" and the fourth layer of the lower hierarchy. In addition, the total amount of content data of each lower layer (second layer, third layer, fourth layer) included in the classification of "Part 1 Primitive/Ancient 1" is obtained.

Note that, at the time of acquiring the data amount of the content data, the CPU 11 refers to the content data 12e, and refers to the content data 12e for each layer (first content data. For example, the item list in each layer, the item list in the lowest layer, etc. You can calculate the amount of data (text data, etc.) and the total amount (data amount of the display layer), or you can calculate the amount of data of the content data of each layer and the total amount of content data including the lower layers for each classification of each layer. It is also possible to prepare data (data amount file) in which the data is set in advance for each content, and to obtain the data amount and the total amount of content data for each classification of each layer from the data amount file.

Note that the data amount of the content data can be the storage capacity (bytes) stored in the memory 12 as the content data 12e. In addition, the amount of content data includes the number of pages when displaying the content data on the touch panel 17, the number of characters in the text of the content data in the case of content consisting mainly of text, the number of images in the case of content such as an illustrated book, and the number of images when displaying the content data on the touch panel 17. In the case of content such as a collection, the number of questions, etc. can be used as the amount of content data.

Next, the CPU 11 selects the content data of the display layer, the content data, and A search screen including hierarchical images representing volumes for each data classification is displayed on the touch panel 17 (step A9). In the electronic dictionary 10 according to the first embodiment, a hierarchical image in a display form (first display form) that allows easy understanding of the volume of each classification of content data is displayed on the screen representing content data of display hierarchy. If the content data of the display hierarchy is an item list, the item list represents the hierarchical image.

The CPU 11 generates an item list in which the display range of each item in the item list is set according to the ratio between the data amount of content data for each item (classification) and the overall amount (data amount of the entire display hierarchy), and Content data (four items of "Part 1 Primitive/Ancient 1" to "Part 4 Modern/Contemporary" in the first layer) is displayed in each item of the list.

FIG. 6 is a diagram showing an example of the search screen D2 that displays the item list at the highest level in the first embodiment. The search screen D2 shown in FIG. 6 displays an item list D21 including four items. The display range of each item in the item list D21 differs depending on the ratio of the data amount of content data for each item (classification) to the data amount of the entire display hierarchy. The item list D21 shown in FIG. 6 has content data (four items: "Part 1 Primitive/Ancient 1" to "Part 4 Modern/Contemporary") arranged vertically, so the display range of each item is They are displayed with different widths (lengths) in the vertical direction.

In the search screen D2 shown in FIG. 6, for example, the first item has the smallest display area (the vertical width is the narrowest), and the fourth item has the widest display area (the vertical width is the widest). As a result, from the ratio of the display area (vertical width) of the first and fourth items, it can be determined that the amount of content data for the first item is about half of the amount of content data for the fourth item. I can understand it.

Note that when displaying an item list in which content data (items) are arranged horizontally, the display range of each item may vary horizontally depending on the amount of content data for each item (category). Is displayed. In addition to displaying the item list in the vertical/horizontal direction, it is also possible to display the item list in which the items are arranged irregularly. In this case as well, the display range of each item is displayed by an area corresponding to the ratio of the data amount of content data for each item (classification) to the total amount (data amount of the entire display hierarchy).

The search screen D2 shown in FIG. 6 shows an example in which all items in the item list are displayed on one screen, but the item list can also be displayed on multiple screens. In this case, for example, the entire item list can be displayed by scrolling the screen.

When displaying all items in the item list on one screen, the entire screen is associated with the entire data amount of the display layer, and the data amount of the content data for each item is displayed according to the ratio of the data amount of the entire display layer to the data amount of the entire display layer. The display range is set by

On the other hand, when displaying all items in the item list on multiple screens, select any item (for example, the first item displayed at the top, the item with the lowest volume, etc.) as the standard item. By setting the width (display range), the widths of other items can be determined based on the width (display range) in accordance with the ratio of the content data of the reference item to the amount of data. Alternatively, the width of one item corresponding to a preset standard data amount may be determined in advance, and the width of each item may be determined based on the ratio of the data amount of content data for each item to the standard data amount. As a result, even if the item list is displayed across multiple screens, the relationship between the amounts of content data of each item can be easily understood from the width of the item.

In this way, by displaying the item list D21 (hierarchical image), it is possible to check the content data of the display hierarchy, and also to check the amount of data (volume for each classification of content data) including the lower hierarchy of multiple items included in the display hierarchy. , can be easily understood by the difference in the area of the display range.

With respect to the item list D1, it is possible to specify (pre-select) an item to be selected by operating the cursor key 16e (in this case, operating the up and down direction keys). In one embodiment, pre-selection may be performed by a single touch of the item with pen 18. The CPU 11 changes the display form of the selected item (for example, reversely displays it) in response to the pre-selection operation by the user to clearly indicate the pre-selected item. The search screen D2 shown in FIG. 6 indicates that the second item D22 has been pre-selected.

Here, when the selection of item D22 is executed by the user's operation of the enter key 16c or the touch operation of the pen 18 (step A10, Yes), the CPU 11 determines that the next layer (lower layer) is the lowest layer. Determine whether As described above, when the CPU 11 executes pre-selection by a single touch operation by the user, the CPU 11 may determine that the item has been selected by the user's double touch on the item, and may proceed to the next step. .

If the next layer (lower layer) is not the lowest layer (step A11, No), the CPU 11 sets the next layer as the display layer and acquires the content data of the display layer (step A12). In addition, the CPU 11 determines the amount of content data including the lower hierarchy for each classification of the selected item (display hierarchy) with respect to the data amount of the content data of the display hierarchy (the data amount of the selection item (classification) of the upper hierarchy). Generate an item list with the display range set, and add content data (two items in the second layer, ``Chapter 4: Establishment of Medieval Society'' and ``Chapter 5: Growth of Samurai Society'') into each item in the item list. Each is displayed (step A13). Note that the display of the item list (hierarchical image) is performed in the same manner as shown in FIG. 6, and detailed description thereof will be omitted. In other words, the display hierarchy can also be referred to as an area occupied by the items included in the hierarchical image of the first display form in the hierarchy to which the items included in the hierarchical image of the first display form belong.

FIG. 7 is a diagram showing an example of the search screen D3 that displays the item list of the second hierarchy in the first embodiment. The search screen D3 shown in FIG. 7 displays an item list D31 including two items. The display range of each item in the item list D31 differs depending on the ratio of the amount of content data for each item (classification) to the amount of content data in the display hierarchy. Further, the item list D31 does not need to fit on one screen. For example, the entire screen may be displayed by scrolling the screen.

In addition, on the search screen D3, the CPU 11 also displays a display format (a first display format) in which the volume of content data in the display hierarchy (items selected in the upper hierarchy) can be easily grasped, in addition to the item list (hierarchical images in the first display format). 2 display format) is displayed (step A14). In FIG. 7, a hierarchical image in the form of a bar (hereinafter referred to as a hierarchical range bar B1) is displayed along the left edge of the display screen of the touch panel 17 (adjacent to the left side of the item list D31).

The hierarchy range bar B1 represents the total data amount of the content data of the display hierarchy (first content data) and the content data of the lower hierarchy of the display hierarchy (second content data), and the range of the display hierarchy in the entire content. That is, it represents the amount of content data including the lower hierarchy of the item selected on the search screen D2 of the previous screen ("Part 2 Medieval" in FIG. 6), and the range of display hierarchy in the entire content. An example of the first content data is an item list.

In the hierarchy range bar B1 shown in FIG. 7, the overall length in the vertical direction represents the data amount of the entire content. In addition, the data amount of the content data (first content data) of the display hierarchy (second hierarchy "Chapter 4, Chapter 5") displayed in the item list D31 and the data amount of the content data (first content data) of the display hierarchy (the third hierarchy) The total data amount and the data amount of the content data (second content data) of each lower hierarchy of Chapters 4 and 5 and the range of the display hierarchy are calculated in the display hierarchy area B11 (first area) of the hierarchy range bar B1. It is represented by The area other than the display hierarchy area B11 of the hierarchy range bar B1 is represented by a non-display hierarchy area B12 (second area). The display hierarchy area B11 and the non-display hierarchy area B12 are displayed in different display formats, and for example, the display hierarchy area B11 uses a display format that is easier to see (for example, brighter tone, brightness, saturation, etc.). .

In this way, on the search screen D3, by displaying the item list D31, it is possible to grasp the volume of each category of content data, similarly to the item list D21 described above, and by using the hierarchy range bar B1, the display hierarchy including the lower hierarchy can be grasped. It is possible to easily grasp the data amount (ratio) of content data to the data amount of the entire content and the range of display hierarchy in the entire content. Furthermore, by displaying the item list D31 (first content data) and the hierarchy range bar B1 adjacent to each other, it is possible to easily confirm the correspondence between the item list D31 and the hierarchy range bar B1.

Next, as shown in FIG. 7, when the second item D32 ("Chapter 5 Growth of Samurai Society") is selected on the search screen D3 (Step A10, Yes), the CPU 11 If there is a (lower hierarchy) (step A11, No), the same process as described above is executed (steps A12 to A14). FIG. 7 shows a state in which item D32 is pre-selected.

FIG. 8 is a diagram showing an example of the search screen D4 that displays the item list of the third hierarchy in the first embodiment. The search screen D4 shown in FIG. 8 displays an item list D41 including four items. The display range of each item in the item list D41 differs depending on the ratio of the amount of content data for each item (classification) to the amount of content data in the display hierarchy.

Furthermore, in addition to the item list (hierarchical images in the first display mode), the search screen D4 additionally displays hierarchical images in a display format (second display format) that allows easy understanding of the volume of the current display hierarchy. Step A14). In FIG. 8, a hierarchy range bar B2 is displayed between the previously displayed hierarchy range bar B1 and the item list D41, adjacent to the hierarchy range bar B1.

The hierarchy range bar B2 shows the total amount of content data (first content data) in the display hierarchy (third hierarchy) and content data (second content data) in the lower hierarchy of the display hierarchy, and the range of the display hierarchy in the entire content. represents. In other words, the content data including the lower hierarchy of the item selected on the search screen D3 on the previous screen (in Figure 7, "Chapter 5 Growth of Samurai Society", that is, the item selected at the next higher level of the display hierarchy). Represents the amount of data and the range of display hierarchies in the entire content.

In the hierarchy range bar B2 shown in FIG. 8, the overall length in the vertical direction represents the data amount of the entire content, similar to the hierarchy range bar B1. In addition, the range of the total data amount of the content data (first content data) of the display hierarchy (third hierarchy) displayed in the item list D41 and the content data of the lower hierarchy (fourth hierarchy) of the display hierarchy is This is represented by the display hierarchy area B21 (first area) of the range bar B2.

The area other than the display hierarchy area B21 of the hierarchy range bar B2 is represented by a first non-display hierarchy area B22 and a second non-display hierarchy area B23. The display hierarchy area B21, the first hidden hierarchy area B22, and the second hidden hierarchy area B23 are displayed in different display formats. For example, the display hierarchy area B11 and the display hierarchy area B21 of the hierarchy range bar B1 are of the same type. A display form that is easy to visually recognize (for example, similar hue, brightness, saturation, etc.) is used. This makes it easy to understand the vertical relationship of the display hierarchy. Furthermore, the first non-display hierarchy area B22 indicates the range of items (classifications) that are not selected in the upper display hierarchy. The first non-display hierarchy area B22 is included in the display hierarchy area B11 of the upper display hierarchy. The second hidden hierarchy area B23 is an area corresponding to the range of the hidden hierarchy area B12, which is not included in the range of the display hierarchy area B11 of the upper display hierarchy. The second hidden hierarchical area B23 is displayed in the same display form as the hidden hierarchical area B12 of the hierarchical range bar B1, for example, and represents a range that is not selected for hierarchy selection.

In this way, on the search screen D4, by displaying the hierarchy range bars B1 and B2 corresponding to each of the different display hierarchies, the data amount ( ratio) and the range of display hierarchies in the entire content. Furthermore, the relationship between the data amount (ratio) and range of items (classifications) between the display hierarchies in the vertical relationship selected by the hierarchy search is displayed in the first display hierarchy area B11 of the hierarchy range bar B1 and the hierarchy range bar B2. This can be easily understood by the correspondence with the hierarchical area B21 (the display hierarchical area B21 is included in the range of the first area B11). By displaying the layer range bars B1 and B2 adjacent to each other, it is made easier to identify the relationship between the display layers that are in a vertical relationship.

Next, as shown in FIG. 8, when the second item D42 ("2 Decline of the Shogunate and Rise of the Common People") is selected on the search screen D4 (Step A10, Yes), the CPU 11 selects the next item D42. Determine whether the hierarchy (lower hierarchy) is the lowest level. As a result, if it is determined that the next layer is the lowest layer (Step A11, Yes), the CPU 11 displays the content data (first content data) of the selected item on the content data screen D5 (Step A15). FIG. 8 shows a state in which item D42 is pre-selected.

FIG. 9 is a diagram showing an example of the content data screen D5 in the first embodiment. The content data screen D5 shown in FIG. 9 includes an item list D51 including a plurality of items provided corresponding to the item D42 on the search screen D4 as content data corresponding to the item selected on the search screen D4, and an item list D51 including a plurality of items provided corresponding to the item D42 on the search screen D4. Text data D52 corresponding to the pre-selected item in the list D51 is displayed. In the example of the content data screen D5 shown in FIG. 9, text data D52 regarding the item "Yoshimasa Ashikaga" pre-selected in the item list D51 is displayed. If the CPU 11 does not support pre-selection by single touch, text data regarding the top item of the item list D51 (in the case of FIG. 9, "Onin War") is displayed.

In addition, to the content data screen D5, in addition to the item list D51 and body data D52, a hierarchical image in a display format (second display format) that allows easy understanding of the volume of content data in the currently displayed hierarchy is added. Display (step A16). In FIG. 9, a hierarchy range bar B3 is displayed adjacent to the hierarchy range bar B2 between the previously displayed hierarchy range bars B1 and B2 and the content data display area (item list D51, body data D52). There is.

The hierarchy range bar B3 represents the amount of content data in the lowest display hierarchy (fourth hierarchy) and the range of the display hierarchy in the entire content. In other words, the content data includes the lower hierarchy of the item selected on the search screen D4 on the previous screen (in FIG. 8, "2 Decline of the Shogunate and Rise of the Common People", that is, the item selected at the next higher level of the display hierarchy). represents the amount of data and the range of display hierarchies in the entire content.

In the hierarchy range bar B3 shown in FIG. 9, the overall length in the vertical direction represents the data amount of the entire content, similar to the hierarchy range bars B1 and B2. Further, the data amount range of the content data of the display hierarchy (lowest layer ((fourth hierarchy)) is represented by the display hierarchy area B31 (first area) of the hierarchy range bar B3.

The area other than the display hierarchy area B31 of the hierarchy range bar B3 is represented by a first non-display hierarchy area B32 and a second non-display hierarchy area B33. The display hierarchy area B31, the first non-display hierarchy area B32, and the second non-display hierarchy area B33 are displayed in different display formats, respectively, in the same way as the hierarchy range bar B2. Furthermore, the display hierarchy area B31 uses the same easily visible display form as the display hierarchy area B11 and the display hierarchy area B21 (for example, similar hue, brightness, saturation, etc.). This makes it easy to understand the vertical relationship of the display hierarchy. Furthermore, the first non-display hierarchy area B32 indicates the range of items (classifications) that are not selected in the upper display hierarchy. The second hidden hierarchical area B33 is displayed in the same display format as the hidden hierarchical area B12 of the hierarchical range bar B1, for example, and represents a range that is not selected for hierarchy selection.

In this way, on the content data screen D5, by displaying the hierarchy range bars B1, B2, and B3 corresponding to each of the different display hierarchies, it is possible to It is possible to easily understand the amount of data (ratio) and the range of display hierarchies in the entire content. Furthermore, the relationship between the data amount (ratio) and range of items (classifications) between the display hierarchies in the vertical relationship selected by the hierarchy search is determined in the first area B11 of the hierarchy range bar B1 and the display hierarchy area of the hierarchy range bar B2. B21 and the display hierarchy area B31 of the hierarchy range bar B3 can be easily understood. By displaying the layer range bars B1, B2, and B3 adjacent to each other, it is made easier to identify the relationship between the display layers that are in a vertical relationship.

In this manner, in the dictionary search process in the electronic dictionary 10 of the first embodiment, it is possible to easily grasp the volume of content data included in the hierarchy to be displayed.

Note that the hierarchical images in the second display format described above (hierarchical range bars B1 to B3 shown in FIGS. 7 to 9) are displayed in the form of a vertically long bar along the left edge of the display screen of the touch panel 17; It is also possible to have a shape. For example, when the item list is arranged horizontally, a hierarchical image (hierarchical range bar) may be displayed in the form of a horizontally long bar along the lower edge of the display screen of the touch panel 17 in accordance with the arrangement of the items. That is, any display form that can represent the total data amount of the content data of the display hierarchy and the lower hierarchy and the range (width, area, length) of the display hierarchy in all the hierarchy may be used.

In addition, in the content data screen D5 shown in FIG. 9, the hierarchy range bars B1 to B3 are displayed together with the content data of the display hierarchy (item list D51, body data D52), but when displaying the content data of the lowest layer, , the hierarchy range bars B1 to B3 may not be displayed. The content data in the lowest layer (main text data D52) is the content that is ultimately to be viewed through the hierarchical search, and has a larger amount of data than the content data (items) displayed in the item list. Therefore, by not displaying the hierarchical range bars B1 to B3, the display area in which the content data can be displayed can be expanded, and the content data (main text data D52) can be viewed easily.

Furthermore, in the above explanation, the hierarchy range bars B1 to B3 are displayed sequentially from the left side of the display screen of the touch panel 17 as the display hierarchy moves to a lower layer, but it is also possible to display them sequentially from the right side of the display screen of the touch panel 17. It's okay.

In addition, in the above explanation, the amount of content data is expressed by the display range of hierarchical images (item list, layer range bar), but it is also possible to use characters that indicate the amount of content data, such as the number of pages, number of characters, number of images, etc. The amount of data may be specifically understood by adding a number or the like representing the amount of data. Furthermore, for example, a scale dividing the entire hierarchical image into equal parts may be added to make it easier to determine the extent of the range corresponding to the display hierarchy.

Further, in the above description, the data amount of the display hierarchy and the range of the display hierarchy are represented by the hierarchy range bar, but data representing the processing status of the content may be added. For example, if you complete learning by displaying the text data of the searched content, answer a question in the content of a problem set, or add a marker to the text data, Data indicating processed text data (processed data) is stored. When displaying the hierarchical range bar, the CPU 11 displays the position indicated by the processed data (body data position, item position included in the text data, etc.) on the hierarchical range bar using, for example, a color that is easy to identify. Thereby, processed (or unprocessed) text data can be easily displayed by hierarchical search while referring to the position indicated by the processed data displayed on the hierarchical range bar.

Further, in the hierarchy range bars B1 to B3, a plurality of areas are displayed in different display formats (colors), but the display formats are not limited to those described above. For example, only the display hierarchy area B11, display hierarchy area B21, and display hierarchy area B31 corresponding to the display hierarchy may be displayed in a special distinguishable color, and all other areas may be displayed in the same color. Furthermore, the color may be changed for each display hierarchy.

(Second embodiment)
Next, dictionary search processing in the second embodiment will be explained. In the dictionary search process in the first embodiment, when any item is selected from the item list, the amount of data of the selected item (content data of the display hierarchy on the next screen (first content data)) is displayed on the next screen. ) and the content data (second content data) in the lower hierarchy of the display hierarchy) and a hierarchy image (layer range bar) representing the range of the display hierarchy in the entire content. Now, a hierarchical image (hierarchical range bar) is displayed according to the item pre-selected from the item list.

FIG. 10 is a flowchart showing dictionary search processing in the second embodiment.

Steps B1 to B8 shown in FIG. 10 execute the same processing as steps A1 to A8 shown in FIG. 4, and a description thereof will be omitted.

Next, the CPU 11 calculates the content data of the display layer and the volume of the content data for each category based on the data amount and total amount (data amount of the entire display layer) of the content data for each category and the content data of the display layer. At the same time as displaying a hierarchical image (item list) in the first display form representing the content data (step B9), displaying a hierarchical image (hierarchical range bar) in the second display form that allows easy understanding of the volume of each classification of content data ( Step B10).

FIG. 11 is a diagram illustrating an example of a search screen D6 that displays a first layer item list in the second embodiment. The search screen D6 shown in FIG. 11 displays an item list D61 including four items and a hierarchy range bar B1. The method for displaying the item list D61 will be omitted as it is executed in the same manner as in the first embodiment.

The hierarchy range bar B1 includes the content data (first content data) of the pre-selected item in the current display hierarchy (first hierarchy) and the content data (second content data) in the lower hierarchy of the pre-selected item. represents the total amount of data and range of pre-selected items in the entire content. The search screen D6 shown in FIG. 11 shows a state in which the second item "Part 2 Medieval" is pre-selected. The display form of the hierarchy range bar B1 is the same as in the first embodiment, and the description thereof will be omitted.

When the user performs a pre-selection operation on the item list D61 on the search screen D6 (step B11, Yes), the CPU 11 changes the display form of the pre-selected item (for example, displays it in reverse video) and displays the pre-selected item. Specify the selected item. In addition, the CPU 11 determines the total data amount of the content data of the pre-selected item and the content data of the lower hierarchy of the pre-selected item, and the total amount of data of the pre-selected item in the entire content, depending on the pre-selected item. The display position of the display hierarchy area B11 on the hierarchy range bar B1 is changed so as to represent the range (specific examples are shown in FIGS. 12 and 13) (step B10).

Here, when the user selects the item D62 on the search screen D6 by operating the enter key 16c or double-touching the pen 18 (step B12, Yes), the CPU 11 selects the item D62 in the next hierarchy (lower level). layer) is the lowest layer.

If the next layer (lower layer) is not the lowest layer (step B13, No), the CPU 11 sets the next layer as the display layer and acquires the content data of the display layer (step B8), and in the same manner as described above, the CPU 11 sets the display layer as the display layer. A search screen D7 including an item list D7 and a hierarchy range bar B2 is displayed on the touch panel 17.

FIG. 12 is a diagram illustrating an example of a search screen D7 that displays a list of items in the second hierarchy in the second embodiment. The search screen D7 shown in FIG. 12 displays an item list D61 including two items and a hierarchy range bar B2.

In the search screen D7 shown in FIG. 12, the first item "Chapter 4: Establishment of Medieval Society" is in a pre-selected state. Therefore, in the hierarchy range bar B2, the total data amount of the content data of the first pre-selected item "Chapter 4: Formation of Medieval Society" and the content data of the lower hierarchy of the pre-selected item and the entire content. A display hierarchy area B21A is displayed to represent the range of pre-selected items. Furthermore, in the hierarchy range bar B2, a first hidden hierarchy area B22A indicating a range of items that have not been pre-selected in the display hierarchy is displayed.

Here, when the user performs a pre-selection operation on the second item D73 of the item list D71 on the search screen D7 (step B11, Yes), the CPU 11 changes the display format of the selected item D73. , to indicate pre-selected items. Further, in accordance with the pre-selected item D73, the CPU 11 determines the total data amount of the content data of the pre-selected item D73 and the content data of the lower hierarchy of the pre-selected item, and the pre-selected data in the entire content. In order to represent the range of items, a display hierarchy area B21B (see FIG. 13) is displayed in place of the display hierarchy area B21A in the hierarchy range bar B2.

FIG. 13 is a diagram showing an example in which the pre-selected items on the search screen D7 in the second embodiment are changed.

In the search screen D7 shown in FIG. 13, the pre-selected item has been changed to the second item "Chapter 5 Growth of Samurai Society." Therefore, in the hierarchy range bar B2, the total data amount of the content data of the second pre-selected item "Chapter 5 Growth of Samurai Society" and the content data of the lower hierarchy of the pre-selected item and the entire content A display hierarchy area B21B is displayed to represent the range of pre-selected items. In addition, in the hierarchy range bar B2, the display hierarchy area B21A that was displayed in the range corresponding to the previously pre-selected item D72 is changed to the first hidden hierarchy area B22B that indicates the range of the item that is not pre-selected. Be changed.

Here, when the selection of an item is executed by the user's operation of the enter key 16c or the double-touch operation of the pen 18 (step B12, Yes), the CPU 11 selects whether the next layer (lower layer) is the lowest layer or not. For example (step B13, Yes), the same process as steps A15 and A16 in the first embodiment is executed to display a content data screen displaying the content data of the lowest layer.

In this way, in the dictionary search process in the electronic dictionary 10 of the second embodiment, in addition to the effects of the first embodiment, the hierarchical range is A bar can be displayed. Thereby, by performing a pre-selection operation, it becomes possible to easily confirm the volume and range of content data including the lower hierarchy of each item on the hierarchy range bar.

(Third embodiment)
In the first and second embodiments, in the item list, the display range of each item is displayed with different widths in the vertical direction depending on the ratio of the data amount of content data for each item to the data amount of the entire display hierarchy. However, the hierarchical image of the first display form of the third embodiment has an item range image that shows the data amount of content data of each item (classification) in the item list relative to the standard data amount. are doing. That is, in the third embodiment, the display range of each item is displayed with different widths depending on the ratio of the amount of content data including the lower hierarchy of each item to the predetermined standard amount of data.

FIG. 14 is a flowchart showing dictionary search processing in the third embodiment.

The dictionary search process shown in FIG. 14 is detailed as being executed in the same manner as the other processes in steps A9 and A13 of the flowchart of the first embodiment shown in FIG. 4, except for steps C9 and C13 for displaying the item list. Further explanations will be omitted.

Based on the amount of content data for each classification and the content data for the display hierarchy, the CPU 11 creates content data for the display hierarchy (first content data) and a hierarchical image (first display) representing the volume of content data for each classification. A search screen including the following format is displayed on the touch panel 17 (step C9). In the electronic dictionary 10 according to the third embodiment, when the content data of the display hierarchy is an item list, a hierarchical image is displayed in a display format that allows easy understanding of the volume of each classification of content data. In other words, for each item, an item list is generated in which an item range image with a display width set according to the amount of content data for each category is added to each item, and the content data is added to each item in the item list. (A specific example of displaying the item list will be described later (FIG. 15)).

Further, if any item is selected in the item list (step C10, Yes), and the next layer (lower layer) is not the lowest layer (step C11, No), the CPU 11 sets the next layer as the display layer, Content data of the display hierarchy is acquired (step C12). The CPU 11 generates an item list in which each item is appended with an item range image with a display width set according to the amount of content data including the lower hierarchy of each item (classification) of the selected item (display hierarchy). Content data is displayed in each item of the list (step C13).

FIG. 15 is a diagram showing an example of an item list to which item range images are added on the search screen D9 in the third embodiment.

In the search screen D9 shown in FIG. 15, the hierarchy range bars B1 and B2 are displayed in the same manner as in the first embodiment, and their explanation will be omitted. In the item list D91 shown in the search screen D9, content data of a plurality of items in the display hierarchy (four items "Yayoi Culture" to "Yamataikoku Union") are arranged at equal intervals in the vertical direction.

Furthermore, a line D92 representing the reference data amount is displayed on the search screen D9. The reference data amount can be, for example, the average value of the data amount including lower layers for each item in the display layer. The reference value may be set based on other data.

Furthermore, an item range image is added to the content data of each item. In the search screen D9 shown in FIG. 15, the item range image is, for example, the range in which the display form (for example, reverse display) is changed to indicate that the item has been pre-selected, that is, the horizontal direction for each item on the search screen D9. is set for the range of . That is, item range images B41, B42, B43, and B44 are added to the content data of the four items, respectively. The item range image B42 is in a pre-selected state and is displayed in a different display form (different color, etc.) from the other item range images B41, B43, and B44.

When any item is selected by an operation using the cursor key 16e or a touch operation using the pen 18, the CPU 11 changes the display form to indicate that the item range image of that item has been pre-selected.

The display width (horizontal display width) of the item range image is determined according to the ratio of the data amount of the content data including the lower hierarchy of each item to the reference data amount indicated by the line D92.

In this way, in the dictionary search process in the electronic dictionary 10 of the third embodiment, in addition to the effects of the first embodiment, the data amount of content data including the lower hierarchy of each item as well as the line D92 representing the standard data amount. By adding an item range image corresponding to the item range image, the volume of data for each item can be easily grasped by comparing it with the reference data amount. Also, since the item range image is set for the horizontal range of each item, the vertical length required for one item is the same regardless of the amount of data, so if there are many items included in the display hierarchy Even in this case, it is possible to represent the amount of data including lower layers corresponding to the content data (first content data) of many items on one screen. The third embodiment can also be applied to the second embodiment described above.

Next, a modification of the display form of the hierarchy range bar in the first to third embodiments will be described.

FIG. 16A is a diagram showing an example of a search screen D10 on which, for example, three hierarchical range bars B1, B2, and B3 are displayed. Here, it is assumed that, for example, the display hierarchy area B21 of the hierarchy range bar B2 is selected by, for example, a touch operation using the pen 18.

In this case, when the CPU 11 detects that the display hierarchy area B21 of the hierarchy range bar B2 has been selected, as shown in FIG. The display of the hierarchy range bar B3 corresponding to the hierarchy is changed.

In the example shown in FIG. 16(B), a second display hierarchy area B21A is displayed in which the entire hierarchy range bar B2 selected by the pen 18 is changed to the same display format as the display hierarchy area B21, and the display hierarchy area B21 is The second display hierarchy area B31A is displayed by expanding the range of the display hierarchy area B31 of the hierarchy range bar B3 using the same magnification (ratio) as the second display hierarchy area B21A.

As shown in FIG. 16(A), the lower the display layer is, the narrower the range of the data amount of the display layer with respect to the entire content (the length of the entire bar), and the data amount of the display layer and the data amount of the upper layer become narrower. Or the relationship with the range becomes difficult to understand. Therefore, by changing the display range corresponding to the display hierarchy to be enlarged according to the range of the hierarchy range bar selected by the user's operation, as shown in FIG. 16(B), the hierarchy range bar can be expanded. It is possible to easily understand the relationship between the display hierarchy and the hierarchical display hierarchy.

Next, bar jump processing for changing the display hierarchy to be displayed using the hierarchy range bar in the first to third embodiments will be described.

FIG. 17 is a flowchart for explaining bar jump processing in this embodiment.

In the first to third embodiments described above, when there is an operation to select any item in the item list, the next lower hierarchy is changed to the display hierarchy, but if the displayed hierarchy range bar is touched Depending on the position specified by the operation, the display is changed according to the touch operation position.

When the CPU 11 detects a touch operation with the pen 18 on the hierarchy range bar (step D1, Yes), the CPU 11 selects a selected hierarchy range bar (corresponding to the display hierarchy) and a position corresponding to the touch operation on the hierarchy range bar. The bar area corresponding to the item in the display hierarchy is specified, and the display hierarchy and item to be displayed are determined (step D2).

The CPU 11 displays a hierarchy range bar and an item list on the touch panel 17 according to the display hierarchy and item to be displayed (step D3).

For example, when the display hierarchy area B21 of the hierarchy range bar B2 shown in FIG. 9 is touched, the item list D41 of the display hierarchy corresponding to the display hierarchy area B21 shown in FIG. The hierarchy range bar B3 corresponding to the lower display hierarchy is deleted.

Furthermore, when the second hidden hierarchical area B33 of the hierarchical range bar B3 shown in FIG. 9 is touched, the item list D51 and the main text data D52 shown in FIG. main text data). Furthermore, the positions of the display hierarchy area B11, display hierarchy area B21, and display hierarchy area B31 in each of the hierarchy range bars B1 to B3 are changed to the range of content data of the display hierarchy currently being displayed.

In this way, by making it possible to change the displayed content using the hierarchy range bar, it is possible to specify any display hierarchy and display content data by selecting one from multiple hierarchy range bars. Can be done. Furthermore, by specifying different positions in one hierarchy range bar, it is possible to display different content data in different upper hierarchies within the same display hierarchy.

In addition, the method described in the embodiment is applied to a memory card (ROM card, RAM card, etc.), magnetic disk (flexible disk, hard disk, etc.), optical disk (CD-ROM, DVD, etc.) as a program that can be executed by a computer. , and can be stored and distributed in a recording medium such as a semiconductor memory. Then, the computer reads the program recorded on the recording medium and has its operations controlled by this program, thereby realizing the same processing as the functions described in the embodiments.

In addition, program data for realizing each method can be transmitted over a network (such as the Internet) in the form of program code, and the program data can be imported from a computer (such as a server device) connected to this network. Functions similar to those of the embodiments described above can also be realized.
