Description

The present invention relates to electronic equipment, display methods, and display programs.

Electronic devices such as electronic dictionaries store various types of content, and can output content arbitrarily selected by a user's operation. Various contents include, for example, dictionaries, encyclopedias, learning reference books, problem collections, literary works, commentaries, and the like. Content data is generally classified according to a hierarchical structure. For example, the content data is classified for each layer such as part, chapter, section, paragraph, and text.

Hierarchical search (also called table of contents search or classified search) is a method for searching content to be displayed from content having a hierarchical structure. In the hierarchical search, by selecting one of the categories (items, etc.) in the upper hierarchy, the content (eg, item list) of the lower hierarchy included in the selected category is displayed. By repeating the operation of selecting one of the categories in each hierarchy, the contents of any hierarchy can be displayed.

Japanese Patent Application Laid-Open No. 2014-63228

Conventionally, when hierarchically searching content having a hierarchical structure, it was difficult to understand the volume of the 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 hierarchy with respect to the contents of the hierarchy to be displayed.

For example, when using the contents of a study reference book, learning progresses while sequentially selecting items and changing the contents of the hierarchy to be displayed by hierarchical search. In such a case, with conventional electronic devices, it was not possible to grasp the amount of learning content including lower layers included in the item to be displayed from an item list or the like.

Therefore, for example, even if you make a study plan of "one chapter per day", there is a big difference in the amount of data of the learning content of each chapter (including section, paragraph, and main text), so you can study steadily. A situation arises where it is not possible.

In addition, conventionally, multiple contents are grouped, the number of pages in the group is calculated, and a book image that reflects the thickness according to the number of pages is displayed, so that the volume of the group can be visually known. It is considered to do (see Patent Document 1). However, since the book image is displayed separately from the display of the content, the volume of the content to be displayed cannot be known, and the volume of each content cannot be known.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-mentioned problems, and provides 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-described problems, an electronic device according to an embodiment of the present invention is an electronic device comprising a control section, wherein the control section controls any display hierarchy of content having a hierarchical structure. Along with the content data, a screen including a hierarchical image in a first display mode is displayed in which the display range for each category of the first content data is set according to the amount of data including the second content data of the lower hierarchy for each category.

ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to provide the electronic device, the display method, and the display program which can grasp the volume of the data contained in the hierarchy made into the display object easily.

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 invention.

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

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

The electronic dictionary 10 also records content data of various types of content such as learning reference books, workbooks, literary works, commentaries, and the like. Various types of content have a hierarchical structure, and the content data is classified for each layer such as part, chapter, section, paragraph, and text, for example. Content data is displayed by selecting an item (classification) for each hierarchy (hierarchical search) by a user's operation.

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

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

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

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

The control programs stored in the memory 12 include a system program that controls the overall operation of the electronic dictionary 10, a server 20 on the externally connected network N, and a communication program for data communication with other electronic devices such as personal computers. is stored. Further, the memory 12 stores a dictionary control program 12a for executing a search function of searching dictionary data or content data for information corresponding to the input data and outputting the information. Based on the dictionary control program 12a, the CPU 11 causes the touch panel 17 (display) to display the information of the content data searched by the search function together with a hierarchical image that makes it possible to easily grasp the volume of the content data. The hierarchical images are displayed, for example, in an item list format (hierarchical images in a first display format and a third display format to be described later) and a bar format display format (hierarchical images in a second display format to be 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 archaic dictionary. The dictionary data 12c includes information such as entry words or text corresponding to each item for each dictionary/dictionary.

The content data 12e is data of various contents such as learning reference books, workbooks, literary works, commentaries, etc., and includes data such as images (still images, moving images) and audio in addition to text. Content data is managed according to a hierarchical structure, and each category (item) of content data in a higher hierarchy includes content data in a lower hierarchy. For example, there are multiple "chapter" content data in the upper hierarchy, each chapter includes multiple "section" content data in the lower hierarchy, and each section further includes multiple "section" content data in the lower hierarchy. Contains "paragraph" content data. The hierarchical structure of each content differs for each content.

Note that the dictionary data 12c and the content data 12e may be obtained from a database (for example, the server 20) that is accessible through the network N, instead of being stored in the main body of the electronic dictionary 10, or may be obtained from a detachable recording medium. 13 may be read out through the recording medium reading unit 14 .

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

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

The key input unit 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, cursor keys (up, down, left, and right keys) 16e, a power button, and others. Various function keys are provided.

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 various menus and buttons according to execution of various functions, and various information such as texts and images in addition to buttons 17a that are always displayed. In one embodiment, the display unit does not have to function as a touch panel. For example, an LCD may be used instead of the touch panel 17 as the display unit.

The electronic dictionary 10 can input instructions from the user according to the user's operation on the key input unit 16 or the touch operation (using the tip of the pen 18 or the fingertip) on menus and buttons displayed on the touch panel 17 . can.

In the electronic dictionary 10 configured as described above, the CPU 11 controls the operation of each circuit part according to the instructions described in the dictionary control program 12a, and the software and hardware operate in cooperation to perform the following operations. Implements the functions described in the description.

FIG. 3 is a diagram showing an example of the hierarchical structure of content in this embodiment. FIG. 3 shows, for example, the hierarchical structure of the contents of a "Japanese History Glossary", showing that there are the second, third, and fourth hierarchies in order from the first hierarchy, which is the highest hierarchy. .

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

Next, the operation of the electronic dictionary 10 according to this embodiment will be described.

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

When an instruction to select any content is input by the user's touch operation on the menu or button displayed on the touch panel 17 or operation on the key input unit 16, the CPU 11 stores the content data of the selected content. 12e is read (step A1). The CPU 11 also 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 to search for an entry word, and a hierarchical search area D11 for instructing a hierarchical search. A button D12 is provided.

Here, when a character is input to the character input area D11 by operating the character input key 16a or the like, it means that 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 that include the input characters at the beginning, and creates a headword list on the touch panel. 17. When characters are subsequently input to the character input area D11 (step A6, No → step A3, Yes), the CPU 11 similarly extracts a headword including the input character at the beginning, and A list is displayed on the touch panel 17 (steps A3 to A6).

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

On the other hand, when an operation to select the hierarchy search button D12 is performed (step A2, hierarchy search), the CPU 11 determines the amount of content data including the lower hierarchy for each classification of the display hierarchy and the content data of the display hierarchy (first content data) and the total amount of the display hierarchy obtained by summing the data amount for each category, and the content data (first content data) of the display hierarchy are obtained (step A8). Here, the highest hierarchy (first hierarchy) is the display hierarchy, and for each classification of the highest hierarchy, the data amount of the content data (second content data) of the lower hierarchy up to the lowest hierarchy included in the classification is Then, the total amount of the display hierarchy (data amount of the entire content when the display hierarchy is the highest hierarchy) is obtained by summing the data amount of the content data of the highest hierarchy and the data amount of the lower hierarchy for each classification.

For example, in the hierarchical structure of the content shown in FIG. Get an item list with items. Also, for each of the four items (classifications) from "Part 1: Primitive/Ancient 1" to "Part 4: Modern/Modern", the amount of content data (second content data) in the lower hierarchy is obtained. That is, for the classification of "Part 1 Primitive/Ancient 1", the data of the content data of the second layer "Chapter 1" to "Chapter 3" of the lower hierarchy included in "Part 1 Primitive/Ancient 1" Further, the data amount of each content data is acquired for the lower layer 3 and the lower layer 4 included in each of "chapter 1" to "chapter 3". In addition, the total amount of content data of each lower layer (second layer, third layer, and fourth layer) included in the classification of “Part 1 Primitive/Ancient 1” is acquired.

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 of each layer (first content data. text data, etc.) and the total amount (data amount of the display layer) may be calculated, or the data amount of the content data of each layer and the total amount of the content data including the lower layers for each classification of each layer may be prepared for each content (data amount file) in which is set in advance, and the data amount and the total amount of content data for each classification of each layer may be obtained from the data amount file.

The data amount of the content data can be the storage capacity (bytes) stored in the memory 12 as the content data 12e. The amount of content data includes the number of pages when the content data is displayed on the touch panel 17, the number of text characters in the content data in the case of content mainly consisting of sentences, the number of images in the case of content such as a picture book, and the number of images. In the case of contents such as collections, the number of questions can be used as the data amount of the content data.

Next, the CPU 11 generates the content data of the display layer and the content based on the data amount and the total amount of the content data for each category (data amount of the entire display layer) and the content data of the display layer (first content data). The touch panel 17 is caused to display a search screen including a hierarchical image representing the volume of each data classification (step A9). In the electronic dictionary 10 according to the first embodiment, a hierarchical image is displayed in a display form (first display form) in which the volume of each classification of the content data can be easily grasped on the screen showing the content data of the display layer. When the content data of the display layer is an item list, the item list represents the layer 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 amount of content data for each item (class) and the total amount (the amount of data for the entire display hierarchy). Content data (four items from "Part 1 Primitive/Ancient 1" to "Part 4 Modern/Modern" in the first layer) are displayed in each item of the list.

FIG. 6 is a diagram showing an example of a search screen D2 displaying an item list of the highest hierarchy in the first embodiment. An item list D21 including four items is displayed on the search screen D2 shown in FIG. The display range of each item in the item list D21 differs according to the ratio of the amount of content data for each item (class) to the amount of data in the entire display hierarchy. In the item list D21 shown in FIG. 6, since the content data (four items from "Part 1 Primitive/Ancient 1" to "Part 4 Modern/Modern") are arranged vertically, 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 narrowest display area (the narrowest vertical width), and the fourth item has the widest display area (the widest vertical width). As a result, it can be determined from the ratio of the display areas (vertical width) of the 1st and 4th items that the data amount of the content data of the 1st item is about half of the data amount of the content data of the 4th item. I can grasp it.

When displaying an item list in which content data (items) are arranged in the horizontal direction, the display range of each item is changed in the horizontal direction according to the amount of content data for each item (class). Is displayed. In addition to the case where the item list is arranged vertically/horizontally, an item list in which each item is arranged irregularly may be displayed. Also in this case, the display range of each item is displayed in an area corresponding to the ratio of the amount of content data for each item (class) to the total amount of data (data amount of the entire display hierarchy).

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

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

On the other hand, when all the items in the item list are displayed on multiple screens, an arbitrary item (for example, the first item displayed at the top, the item with the lowest volume, etc.) can be used as a reference item. By setting the width (display range), the width of other items can be determined according to 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 reference data amount may be determined in advance, and the width of each item may be determined from the ratio of the data amount of content data for each item to the reference data amount. As a result, even when the item list is displayed over a plurality of screens, it is possible to easily grasp the relationship between the data amounts of the content data of each item from the width of the item.

In this way, by displaying the item list D21 (hierarchical image), it is possible to confirm 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 a plurality of items included in the display hierarchy. , can be easily grasped by the difference in the area of the display range.

For the item list D1, an item to be selected can be specified (pre-selected) by operating the cursor key 16e (here, operating the up and down direction keys). In one embodiment, pre-selection may be performed by single-touching an item with pen 18 . The CPU 11 changes the display form of the selected item (for example, reverse display) according to the pre-selection operation by the user, and clearly indicates 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 user selects the item D22 by operating the determination key 16c or by touching with the pen 18 (step A10, Yes), the CPU 11 selects the next layer (lower layer) as the lowest layer. determine whether As described above, when the CPU 11 executes pre-selection by the user's single-touch operation, the CPU 11 may determine that the item has been selected by the user's double-touch, and proceed to the next step. .

If the next layer (lower layer) is not the lowest layer (step A11, No), the CPU 11 acquires the content data of the display layer as the display layer (step A12). In addition, the CPU 11 determines the data amount of the content data including the lower hierarchy for each classification of the selection 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 enter content data (two items in the second layer, "Chapter 4 Establishment of Medieval Society" and "Chapter 5 Growth of Samurai Society") in each item of 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 in the case shown in FIG. 6, and detailed description thereof will be omitted. In other words, the display hierarchy can also be said to be an area occupied by the items included in the hierarchical image in the first display format in the hierarchy to which the items included in the hierarchical image in the first display format belong.

FIG. 7 is a diagram showing an example of the search screen D3 displaying the item list of the second layer in the first embodiment. An item list D31 including two items is displayed on the search screen D3 shown in FIG. The display range of each item in the item list D31 differs according to the ratio of the amount of content data for each item (class) to the amount of content data in the display layer. Also, the item list D31 does not have to fit on one screen. For example, the entire screen may be displayed by scrolling the screen.

In the search screen D3, the CPU 11 also provides a display form (the first 2 display mode) is displayed (step A14). In FIG. 7, along the left edge of the display screen of the touch panel 17 (adjacent to the left side of the item list D31), a hierarchical image in a bar format (hereinafter referred to as a hierarchical range bar B1) is displayed.

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

In the layer range bar B1 shown in FIG. 7, the total 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 display hierarchy lower hierarchy (third hierarchy) The total amount of data (the second content data) and the range of display layers are displayed in the display layer area B11 (first area) of the layer range bar B1. is represented by A layer range bar B1 other than the display layer area B11 is represented by a non-display layer area B12 (second area). The display layer area B11 and the non-display layer area B12 are displayed in different display modes. For example, the display layer area B11 uses a display mode (e.g., bright color tone, brightness, saturation, etc.) that is easier to see. .

In this way, by displaying the item list D31 on the search screen D3, the volume of each content data category can be grasped in the same manner as the item list D21 described above, and the display hierarchy including the lower hierarchy can be determined by the hierarchy range bar B1. It is possible to easily grasp the data amount (ratio) of the content data to the data amount of the entire content and the range of display layers in the entire content. Also, by displaying the item list D31 (first content data) and the layer range bar B1 adjacent to each other, it is possible to easily confirm the correspondence between the item list D31 and the layer 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 (lower hierarchy) (step A11, No), the same processing 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 a search screen D4 displaying an item list of the third layer according to the first embodiment. An item list D41 including four items is displayed on the search screen D4 shown in FIG. The display range of each item in the item list D41 differs according to the ratio of the amount of content data for each item (class) to the amount of content data in the display hierarchy.

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

The layer range bar B2 shows the total data amount of the content data (first content data) of the display layer (third layer) and the content data (second content data) of the lower layer of the display layer and the display layer range of the entire content. represents That is, the content data including the lower hierarchy of the item selected on the search screen D3 of the previous screen ("Chapter 5 Growth of Samurai Society" in FIG. 7, that is, the item selected in the hierarchy one level higher than the display hierarchy) Represents the amount of data and the range of display layers in the entire content.

In the hierarchy range bar B2 shown in FIG. 8, the total length in the vertical direction represents the data amount of the entire content, as in the hierarchy range bar B1. Further, the range of the total data amount of the content data (first content data) of the display layer (third layer) displayed in the item list D41 and the content data of the lower layer (fourth layer) of the display layer is It is represented by a display layer 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 layer area B21, the first non-display layer area B22, and the second non-display layer area B23 are displayed in different display modes. A display form that is easy to see (eg, similar hue, brightness, saturation, etc.) is used. This makes it possible to easily grasp that there is a hierarchical relationship between display layers. Also, the first non-display layer area B22 indicates the range of items (classifications) that have not been selected in the upper display layer. The first non-display layer area B22 is included in the range of the display layer area B11 of the upper display layer. The second non-display layer area B23 is an area corresponding to the range of the non-display layer area B12 that is not included in the range of the display layer area B11 of the upper display layer. The second non-display layer region B23 is displayed in the same display form as the non-display layer region B12 of the layer range bar B1, for example, and represents a range that is not selected for layer selection.

In this way, on the search screen D4, by displaying the layer range bars B1 and B2 corresponding to the different display layers respectively, the data amount ( ratio) and the range of display layers in the entire content can be easily grasped. Furthermore, the relationship between the data amount (ratio) and the range of items (classifications) between display hierarchies selected by the hierarchical search is displayed in the first display hierarchy area B11 of the hierarchy range bar B1 and the hierarchy range bar B2. It can be easily grasped 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 hierarchy range bars B1 and B2 adjacent to each other, it is easy to identify the relationship between the displayed hierarchies in the 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 performs the following: Determine whether the hierarchy (lower hierarchy) is the lowest. As a result, when the next layer is determined to be 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 of the search screen D4 as content data corresponding to the item selected on the search screen D4, and an item list D51. Text data D52 corresponding to the item pre-selected in the list D51 is displayed. In the example of the content data screen D5 shown in FIG. 9, text data D52 related to the item "Yoshimasa Ashikaga" pre-selected in the item list D51 is displayed. When the CPU 11 does not support pre-selection by single touch, text data relating to the topmost item (“Onin no Ran” in the case of FIG. 9) of the item list D51 is displayed.

In addition to the item list D51 and the text data D52, the content data screen D5 is added with a hierarchical image in a display form (second display form) that makes it easy to grasp the volume of the content data in the current display target hierarchy. 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, text data D52). there is

The layer range bar B3 represents the data amount of the content data of the lowest display layer (fourth layer) and the display layer range of the entire content. That is, the content data including the lower hierarchy of the item selected on the search screen D4 of the previous screen (in FIG. 8, "2 Decline of the shogunate and rise of the common people", that is, the item selected in the hierarchy one level higher than the displayed hierarchy). It represents the amount of data in and the range of display layers in the entire content.

In the hierarchical range bar B3 shown in FIG. 9, the total length in the vertical direction represents the data amount of the entire content, as with the hierarchical range bars B1 and B2. In addition, the range of the data amount of the content data of the display hierarchy (lowest layer ((fourth hierarchy))) is represented by the display hierarchy region B31 (first region) of the hierarchy range bar B3.

A first non-display hierarchical area B32 and a second non-display hierarchical area B33 represent areas other than the display hierarchical area B31 of the hierarchical range bar B3. The display layer area B31, the first non-display layer area B32, and the second non-display layer area B33 are displayed in different display modes, similar to the layer range bar B2. In addition, the display layer area B31 uses an easy-to-visual display form similar to that of the display layer area B11 and the display layer area B21 (for example, similar hue, brightness, saturation, etc.). This makes it possible to easily grasp that there is a hierarchical relationship between display layers. Also, the first non-display hierarchy area B32 indicates the range of items (classifications) that are not selected in the upper display hierarchy. The second non-display layer region B33 is displayed in the same display form as the non-display layer region B12 of the layer range bar B1, for example, and represents a range that is not selected for layer selection.

In this way, on the content data screen D5, by displaying the layer range bars B1, B2, and B3 respectively corresponding to the different display layers, the content data of the display layers including the lower layers of each display layer can be It is possible to easily grasp the amount of data (ratio) and the range of display layers in the entire content. Furthermore, the relationship between the data amount (ratio) and the range of the items (classifications) between the hierarchical display layers selected by the hierarchical search is displayed in the first area B11 of the hierarchical range bar B1 and the display hierarchical area of the hierarchical range bar B2. B21 and the correspondence with the display layer area B31 of the layer range bar B3 can be easily grasped. By displaying the hierarchy range bars B1, B2, and B3 adjacent to each other, it is easy to identify the relationship between the displayed hierarchies in the vertical relationship.

In this manner, in the dictionary search processing 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 mode described above (hierarchical range bars B1 to B3 shown in FIGS. 7 to 9) are displayed in a vertically long bar format along the left edge of the display screen of the touch panel 17. A shape is also possible. For example, when the item list is arranged in the horizontal direction, a hierarchical image (hierarchical range bar) may be displayed in a horizontal bar format along the bottom edge of the display screen of the touch panel 17 according to the arrangement of the items. In other words, any display mode may be used as long as it can represent the total amount of data of the display hierarchy and the content data of the lower hierarchy and the range (width, area, length) of the display hierarchy in all the hierarchies.

In the content data screen D5 shown in FIG. 9, the content data of the display layer (item list D51, body data D52) and the layer range bars B1 to B3 are displayed. , the hierarchy range bars B1 to B3 may not be displayed. The content data (text data D52) in the lowest layer is the content to be finally browsed by 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 (text data D52) can be easily browsed.

In the above description, the hierarchy range bars B1 to B3 are sequentially displayed from the left side of the display screen of the touch panel 17 as the display hierarchy shifts to the lower layers. can be

In the above description, the data volume of the content data is represented by the display range of the hierarchical image (item list, hierarchy range bar). The amount of data may be specifically grasped by adding a number or the like representing . Further, the hierarchical image may be added with scales that divide the entire image into equal parts, for example, so that it is possible to easily determine how much the range corresponding to the displayed hierarchical level is.

In the above description, the layer range bar represents the amount of data in the display layer and the range of the display layer, but data representing the status of processing for the content may be added. For example, when a process such as completion of learning by displaying the text data of the retrieved content, answering a question in the contents of the problem collection, or adding a marker to the text data is executed, the 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 (text data position, item position included in the text data, etc.) in the hierarchical range bar using, for example, an easily identifiable color. Thereby, the processed (or unprocessed) text data can be easily displayed by hierarchical search while referring to the position indicated by the processed data displayed in the hierarchical range bar.

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

(Second embodiment)
Next, dictionary search processing in the second embodiment will be described. In the dictionary search processing in the first embodiment, when any item is selected from the item list, the amount of data of the selected item (the content data of the display hierarchy on the next screen (first content data ) and content data (second content data) in the lower hierarchy of the display hierarchy), and a hierarchy image (hierarchy range bar) representing the range of the display hierarchy in the entire content is displayed. displays a hierarchical image (hierarchical range bar) 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 description thereof is omitted.

Next, the CPU 11 calculates the content data of the display hierarchy and the volume of the content data for each classification based on the data amount and the total amount of the content data for each classification (data amount of the entire display hierarchy) and the content data of the display hierarchy. Display a hierarchical image (item list) in the first display form representing (step B9), and display a hierarchical image (hierarchical range bar) in the second display form that can easily grasp the volume of each classification of content data ( Step B10).

FIG. 11 is a diagram showing an example of a search screen D6 that displays an item list of the first layer according to the second embodiment. An item list D61 including four items and a hierarchical range bar B1 are displayed on the search screen D6 shown in FIG. The method of displaying the item list D61 is omitted because it is performed in the same manner as in the first embodiment.

The hierarchy range bar B1 shows 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) of the lower hierarchy of the pre-selected item. and the 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 Middle Ages" has been pre-selected. The display form of the hierarchical range bar B1 is the same as in the first embodiment, and the description thereof is 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, reverse display) to display the pre-selected item. Indicate the selected item. In addition, the CPU 11 determines, according to the pre-selected item, 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 data amount of the pre-selected item in the entire content. The display position of the display layer area B11 in the layer range bar B1 is changed so as to represent the range (specific examples are shown in FIGS. 12 and 13) (step B10).

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

If the next hierarchy (lower hierarchy) is not the lowest hierarchy (step B13, No), the CPU 11 takes the next hierarchy as the display hierarchy and acquires the content data of the display hierarchy (step B8). A search screen D7 including an item list D7 and a hierarchical range bar B2 is displayed on the touch panel 17. - 特許庁

FIG. 12 is a diagram showing an example of a search screen D7 displaying an item list of the second hierarchy according to the second embodiment. An item list D61 including two items and a hierarchical range bar B2 are displayed on the search screen D7 shown in FIG.

In the search screen D7 shown in FIG. 12, the first item "Chapter 4 Establishment of Medieval Society" is pre-selected. For this reason, in the hierarchy range bar B2, the total data amount of the content data of the first pre-selected item "Chapter 4 Establishment of Medieval Society" and the content data of the lower layers of the pre-selected item and the entire content A display layer area B21A is displayed so as to represent the range of pre-selected items in . Also, in the hierarchy range bar B2, a first non-display hierarchy area B22A indicating the range of items that are not pre-selected in the display hierarchy is displayed.

Here, when the user performs a pre-selection operation for the second item D73 of the item list D71 on the search screen D7 (step B11, Yes), the CPU 11 changes the display form of the selected item D73. , to specify the pre-selected item. In addition, the CPU 11 determines, according to the pre-selected item D73, 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 amount in the entire content. A display hierarchy area B21B (see FIG. 13) is displayed instead of the display hierarchy area B21A in the hierarchy range bar B2 so as to represent the range of items.

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

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". For this reason, in the layer 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 layers of the pre-selected item and the entire content A display layer area B21B is displayed so as to represent the range of pre-selected items in . In the hierarchy range bar B2, the display hierarchy area B21A displayed in the range corresponding to the previously pre-selected item D72 is changed to the first non-display hierarchy area B22B indicating the range of items not pre-selected. Be changed.

Here, when the user selects an item by operating the enter key 16c or by double-touching with the pen 18 (step B12, Yes), the CPU 11 determines whether the next layer (lower layer) is the lowest layer. If (step B13, Yes), the same processing as in steps A15 and A16 in the first embodiment is executed to display a content data screen displaying content data of the lowest layer.

In this manner, in the dictionary search processing in the electronic dictionary 10 of the second embodiment, in addition to the effects of the first embodiment, the hierarchical range is set according to the preselection before any item in the item list is selected and confirmed. bar can be displayed. This makes it possible to easily confirm the volume and range of the content data including the lower layer of each item on the layer range bar by the pre-selection operation.

(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 according to the ratio of the amount of content data for each item to the amount of data in the entire display hierarchy. However, the hierarchical image in the first display form of the third embodiment has an item range image showing the data amount of the content data of each item (classification) in the item list relative to the reference data amount. are doing. That is, in the third embodiment, the display range of each item is displayed with different widths according to the ratio of the data amount of the content data including the lower layer of each item to the predetermined reference data amount.

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

The dictionary search process shown in FIG. 14 is executed in the same manner as steps A9 and A13 in the flowchart of the first embodiment shown in FIG. 4 except for steps C9 and C13 for displaying the item list. detailed description is omitted.

Based on the data amount of the content data for each classification and the content data of the display hierarchy, the CPU 11 generates the content data of the display hierarchy (first content data) and the hierarchical image representing the volume of each classification of the content data (first display data). form) 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 layer is an item list, a hierarchical image is displayed in a display format that allows the volume of each category of the content data to be easily grasped. That is, for each item, an item list is generated in which an item range image in which a display width is set according to the amount of content data for each category is added to each item, and content data is added to each item in the item list. Each item is displayed (a specific example of displaying the item list will be described later (FIG. 15)).

Further, when any item is selected in the item list (step C10, Yes), if the next layer (lower layer) is not the lowest layer (step C11, No), the CPU 11 treats the next layer as the display layer, Content data of the display layer is acquired (step C12). The CPU 11 generates an item list to which an item range image with a display width set according to the data amount of the content data including the lower hierarchy for each item (classification) of the selection item (display hierarchy) is added to each item. 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 an item range image is added on the search screen D9 according to the third embodiment.

In the search screen D9 shown in FIG. 15, the hierarchical range bars B1 and B2 are displayed in the same manner as in the first embodiment, and description thereof is omitted. In the item list D91 shown on the search screen D9, the content data of a plurality of items in the display hierarchy (four items "Yayoi Culture" to "Yamatai Alliance") are arranged at regular intervals in the vertical direction.

A line D92 representing the reference data amount is also displayed on the search screen D9. The reference data volume can be, for example, the average value of the data volume including the lower hierarchy for each item of the display hierarchy. The reference value may be set based on other data.

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, a range in which the display form (for example, reverse display) is changed so as to indicate that the item has been pre-selected, that is, the horizontal direction of 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 display mode (different color, etc.) different from the other item range images B41, B43, and B44.

When any item is selected by an operation with the cursor key 16e or a touch operation with the pen 18, the CPU 11 changes the display form so that the item range image of that item is 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 layer of each item to the reference data amount indicated by the line D92.

In this way, in the dictionary search processing in the electronic dictionary 10 of the third embodiment, in addition to the effects of the first embodiment, the line D92 representing the reference data amount and the data amount of the content data including the lower layers of each item are displayed. By adding an item range image corresponding to the , the data volume of each item can be easily grasped by comparison 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. However, the amount of data including the lower layers corresponding to the content data (first content data) of many items can be displayed on one screen. The third embodiment can also be applied to the second embodiment described above.

Next, modified examples of the display form of the hierarchical 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, for example, it is assumed that the display layer area B21 of the layer range bar B2 is selected by a touch operation with the pen 18, for example.

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

In the example shown in FIG. 16B, 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 form as the display hierarchy area B21, and the display hierarchy area B21 is displayed. A second display layer area B31A obtained by enlarging the range of the display layer area B31 of the layer range bar B3 is displayed at the same scale factor (ratio) as the enlargement of the second display layer area B21A.

As shown in FIG. 16A, the lower the display hierarchy, the narrower the range of the data amount of the display hierarchy with respect to the entire content (the length of the entire bar). Alternatively, the relationship with the range becomes difficult to understand. Therefore, according to the range of the hierarchy range bar selected by the user's operation, as shown in FIG. It is possible to easily grasp the relationship with the display hierarchy that is in the vertical relationship by.

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 displayed hierarchy. The display is changed according to the touch-operated position according to the position specified by the operation.

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

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

For example, when the display layer area B21 of the layer range bar B2 shown in FIG. 9 is touch-operated, the item list D41 of the display layer corresponding to the display layer area B21 shown in FIG. Delete the layer range bar B3 corresponding to the lower display layer.

Further, when the second non-display hierarchical region B33 of the hierarchical range bar B3 shown in FIG. 9 is touch-operated, the item list D51 and the text data D52 shown in FIG. text data). Also, the positions of the display layer area B11, the display layer area B21, and the display layer area B31 in each of the layer range bars B1 to B3 are changed to the range of the content data of the display layer to be displayed at present.

In this way, by making it possible to change the display contents using the hierarchy range bar, it is possible to specify an arbitrary display hierarchy and display the contents data by selecting one from a plurality of hierarchy range bars. can be done. Also, by designating different positions in one layer range bar, it is possible to display different content data of different upper layers within the same display layer.

Further, the methods described in the embodiments can be applied to programs that can be executed by a computer, such as memory cards (ROM cards, RAM cards, etc.), magnetic disks (flexible disks, hard disks, etc.), optical disks (CD-ROM, DVD, etc.). , can be stored in a recording medium such as a semiconductor memory and distributed. Then, the computer reads the program recorded in the recording medium, and by controlling the operation by this program, it is possible to implement the same processing as the functions described in the embodiments.

In addition, program data for realizing each method can be transmitted in the form of program code over a network (Internet, etc.), and program data is captured from a computer (server device, etc.) connected to this network, Functionality similar to the previously described embodiments may also be implemented.

It should be noted that the present invention is not limited to the embodiments, and can be variously modified in the implementation stage without departing from the gist of the invention. Furthermore, the embodiments include inventions at various stages, and various inventions can be extracted by appropriate combinations of the disclosed multiple constituent elements. For example, even if some components are deleted from all the components shown in the embodiments, or some components are combined, the problems described in the column of problems to be solved by the invention can be solved, and the invention If the effect described in the effect column of 1 above can be obtained, a configuration in which this constituent element is deleted or combined can be extracted as an invention.
