DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a knowledge presenting apparatus for assisting a person in acquiring knowledge, for example, to "memorize" knowledge such as CAI, particularly English words, kanji, and historical eras.

[0002]

2. Description of the Related Art Conventionally, printed publications such as reference books and wordbooks have been used for knowledge acquisition activities such as memorizing English words, kanji, and historical eras. Printed publications provide all users with the same knowledge in the same configuration and presentation method. Each user looks at the provided knowledge and makes an effort to memorize the knowledge.

[0003] However, humans have individual differences. In the knowledge acquisition activity of “memorizing”, individual differences appear as differences in knowledge acquisition efficiency. For example, when presenting to a large number of humans an English word to be memorized and its meaning in the same presentation method, one could easily memorize the English word,
Others struggled to memorize, and some gave up.

[0004]

In the above-described method using a print publication, the user's knowledge acquisition activity efficiency cannot be maintained at a high and constant level.

[0005] It is an object of the present invention to provide a knowledge presenting apparatus that supports individual users in a knowledge acquisition activity of memorizing knowledge.

[0006]

According to a first aspect of the present invention, there is provided a knowledge presentation apparatus for inputting at least one piece of information relating to a predetermined user, and a knowledge to be acquired by the user. A knowledge database for storing at least one predetermined attribute of the knowledge; a component of an expression for presenting the knowledge to a user;
A component information database that stores the attributes of the component elements of the expression, and a comparison between the information on the user and the predetermined item of the attribute value attached to each knowledge to be acquired, A knowledge importance determining means for determining a value of the importance of the knowledge to be acquired from at least two ranks, and a relationship between the importance and a predetermined type of expression;
By referring to this, the structure of the expression according to the importance of the knowledge to be acquired is referred to.
Means for determining a component as a selection candidate element, and the component

Display means.

[0008] The knowledge presentation apparatus according to claim 3 of the present invention further comprises a user information database in which information on the user is stored, the determined display format, information for identifying the user, and the user input. means for storing the information about the user in the user information database, identify the user
A means for inputting a different information, means for comparing, searching the display format using previously and information identifying the user in the user information database information identifying the inputted user .

[0009]

According to the present invention, components of a screen for presenting knowledge and its presentation rules are selected based on the importance of the knowledge determined by the attributes of the user, and the knowledge is provided to the user based on the selected elements and the presentation rules. It should be presented.

[0010] According to the first aspect of the present invention, the knowledge to be acquired is selected from the database storing the candidates of the knowledge to be acquired by the user, using the characteristics of the user input by the user. For each of the obtained knowledge, the appropriate rank among the multiple importance ranks, such as the knowledge that should be acquired especially using the characteristics of the user and the knowledge that is expected to be acquired, is assigned. It is characterized in that important information is accurately presented to a user by adding a degree and changing a display mode when displaying knowledge to the user according to the added rank.

For example, assuming that 200 words must be stored based on the characteristics of the user, and 10 words of the words must be stored with the highest priority. By displaying the ten most important words using a display format different from the other 190 words,
The user can easily identify the ten most important words, and can easily pay attention to the ten words.

If the user has to store ten words of the same importance, even if the components and expressions of these ten knowledges are different and presented in a form different from other knowledge, The user who sees these ten types of presentation forms needs to be able to judge that these ten are equally important.

Therefore, according to a second aspect of the present invention, elements such as a sentence, a figure, and a moving image which are used to compose a screen for presenting knowledge to a user are selected from a database in which these elements are stored using characteristics of the user. Means for comparing the attribute of the selected element with the importance of the knowledge to be acquired and the attribute of a predetermined arrangement format to determine a form in which the selected component is presented; The present invention is characterized in that knowledge is presented to the user in an expression corresponding to the user.

Further, according to the second aspect of the present invention, by changing the presentation form of the knowledge, it is easy to promote the differentiation of the knowledge, which is one step when the user understands the knowledge.

When the same knowledge is repeatedly acquired as a characteristic generally observed by humans, it is easier to memorize and learn more effectively when viewing the same presentation screen many times than when viewing different presentation screens each time. This is known as the rehearsal effect (eg, Waugh, NC & Norman, D.
A., A primary memory, Psychological Review, Vol. 7
2, pp. 89-104, 1965).

Therefore, according to a third aspect of the present invention, information about a user including history information of knowledge presentation is stored, and when the user repeatedly learns, the information about the user is automatically saved. It is characterized in that the user only sets the attribute value, checks the set attribute value, and makes corrections as necessary.

As described above, the provision of the user information setting means that has been automated to some extent can reduce the user's labor without losing the flexibility in acquiring the characteristic information of the user.

As described above, the knowledge presentation screen created by the means according to the present invention is adapted to the ability of the user, the interest of the user to the presented knowledge, and the necessity. Such a presentation screen assists the user in understanding and assists in memory. In addition, if the same user repeatedly acquires the same knowledge, the same screen is always presented unless the characteristics of the user change,
Help users remember knowledge.

[0019]

Next, embodiments of the present invention will be described with reference to the drawings. << Embodiment 1 >> FIG. 1 is a block diagram showing a configuration of a knowledge presenting apparatus according to an embodiment of the present invention.

The user information input unit 10 receives information about a user from the user. The user information database 11 stores information on the user himself and his learning. The knowledge database 12 stores knowledge to be acquired by the user and information on each of the knowledge. The component information database 13 stores information on components of the knowledge presentation screen. Available elements are collected and stored for each knowledge. The presentation rule database 14 stores rules for presenting components on the screen. The component element database 15 stores component elements together with element numbers. The knowledge importance determination section 16 determines the importance of each knowledge. The screen component selection unit 17 selects, from the component information database 13, the numbers of elements such as texts, figures, and images that constitute the presentation screen. The screen configuration unit 18 configures a knowledge presentation screen. The screen composition unit 18 registers the components used for the construction of the knowledge presentation screen and the numbers of the presentation rules in the user information 101, and then sends the user information 101 to the user information database 11. The output unit 19 includes a device for providing components, a display for outputting a screen configured by the screen configuration unit 18, and the like. The output unit 19 also has a role of connecting the user to the apparatus, such as displaying a message to obtain information from the user.

Next, the procedure for transmitting data between the components of the apparatus shown in FIG. 1 will be described.

A user who uses the apparatus for the first time inputs user information 101 in the user information input section 10.
A screen for inputting the user information 101 is illustrated in FIG. The user information 101 in one embodiment includes, for example, “name”, “age”, “occupation”, “professional”, “English history”, “substantial academic ability” of the user.
There are items such as "interest". Since “real scholastic ability” is set by the system, it is an item not to be input. In the user information input unit 10, the input "occupation" and "English history"
The item data is also converted by the conversion table possessed by the item. The setting of “substantial academic ability” is also performed in the user information input unit 10. From the second use, when the user inputs a name, the user information database 11
The user information 101 is referred to the data stored in the
Is automatically registered, and the user can simply confirm and correct.

The user information 101 input and set in the user information input unit 10 is sent to the knowledge importance determining unit 16.

The knowledge importance determining section 16 determines the knowledge stored in the knowledge database 12 based on the knowledge importance determination rules possessed therein and the user information 101 received from the user information input section 10. The importance of the presentation target knowledge is determined for each, and importance information 102 is created. Then, the knowledge number and importance of the knowledge data whose importance is not 0 are sent to the screen component selection unit 17 together with the user information 101 as knowledge number information 103 and importance information 102, respectively.

The screen component selection unit 17 presents each knowledge based on the component selection rules possessed therein and the user information 101, importance information 102 and knowledge number information 103 received from the knowledge importance determination unit 16. The number of the component data such as a sentence, a photograph, and a video image used for the screen to be used is selected from the component information database 13.
Then, the number of the selected component is used as the use
As user information 101, importance information 102,
The information is sent to the screen composition unit 18 together with the knowledge number information 103.

The screen composition unit 18 determines the composition of a screen for presenting knowledge. Specifically, a process in which the rules in the presentation rule database 14 are applied according to the importance information 102 and the value of each item of the screen design table 105 is determined according to the result. Then, the completed screen design table 105 is sent to the output unit 19. Also, the screen composition unit 18
Registers the components used in the knowledge presentation screen configuration and the numbers of the presentation rules in the user information 101, and then registers the user information 1
01 to the user information database 11. In the user information database 11, the transmitted user information 101
Save for future use.

The output unit 19 fetches knowledge from the knowledge database 12 based on the basic rules for arranging components held therein and the received screen design table 105, and arranges them together with components fetched from the component database 15. To present a knowledge presentation screen.

FIGS. 3 to 6 are flowcharts showing the processing procedure in this embodiment. The manner in which the apparatus shown in FIG. 1 executes processing and presents knowledge according to the procedure shown in the flowcharts of FIGS.

Assume that the user is a high school student of the sciences having the third grade of Eiken.

The user information input unit 10 presents a user information input screen as shown in FIG. 2 to the user in step 31 and requests the user to input information relating to the user.

As shown in FIG. 7 and FIG.
As for the items of “specialization” and “English history”, selection candidates are presented, and the selected one is input. The selection target field of the “specialty” item changes according to the “occupation” input by the user. For example, if "occupation" is entered as "university 3rd or 4th year", the selected field of the "specialization" item will be "literature / agriculture / engineering / physics / education ...", and "occupation" will be referred to as "employee". Then, the selected fields will be “Steel / Sales / General Affairs / Technology…, Banks / Sales / General Affairs…”. The item “interest” is an item for designating a specialty field or the like that the user wants to study with particular emphasis at that time.
The "real scholastic ability" does not appear on the input request screen because the system determines and sets it based on the values of "occupation" and "English history".

By the way, from the users of this time, the user who is named: user A, age = 18 years old, occupation = 3 years of high school, professional = science, English history = Engen 3rd grade, interest = nothing in particular Information 101
was gotten.

The user information input unit 10 uses the occupation data conversion table (Table 1) possessed therein to change the “occupation” data to “high school 3rd year” in order to simplify future data operations. To “3” and re-register.

[0034]

[Table 1] In step 32, the "English history" data is also converted. Table 2
Is replaced with the data value of the "English history symbol" item in the English history correspondence table, and is re-registered. In this case, "Eiken Level 3"
To “3”.

[0035]

[Table 2] The “English history symbol” item in the English history correspondence table takes any value from “1 (rank)” to “6 (rank)”. These ranks have the same settings as the ranks taken in the "occupation" item. In other words, if the "occupation" data is "3", high school students are indicated, and "5" indicates college course students or graduate students. A score of "5" indicates that the student has the academic ability of a college professional or graduate student.

After the conversion of the "occupation" and "English history" data, in step 33 the "substantial academic ability" is set by the system. The "real scholastic ability" data is the larger value of the converted "occupation" data and "English history" data,
Register in the user information 101. This time, since both are “3”, the “real scholastic ability” data also takes a value of “3”.

The user information 10 set as described above
1 is sent to the knowledge importance determination section 16 in step 34.

The knowledge importance determining section 16 extracts the knowledge to be presented and its accompanying data from the knowledge database 12 at step 35. Then, in step 36, the auxiliary data of each knowledge and the user information 101 according to the knowledge importance determination rule.
Are collated, and the importance is determined in step 37 based on the result.

FIG. 9 shows an example of the rule for judging the importance of knowledge referred to in step 36.

In the knowledge database 12 storing English words and their meanings as "knowledge", knowledge data is stored in a format as shown in Table 3.

[0041]

[Table 3] Knowledge data includes items of attached data such as "knowledge number", "field", and "suitability" in addition to "word knowledge" and "semantic knowledge" which are knowledge. The “field” is information indicating a profession / academic field where “semantic knowledge” is frequently used. The knowledge importance determining unit 16 uses the field / specialty correspondence table exemplified in Table 4 to calculate the “field” data and the “specialty” of the user information 101.
Take correspondence with the data entered in the item. Then, "field" data and "specialization" performed with reference to this correspondence table
Data collation is one of the procedures for determining the importance of knowledge.

[0042]

[Table 4] “Aptitude” is information indicating an appropriate time to teach the “knowledge”. Table 5 exemplifies the criteria for the “suitability”. Matching the “fitness” data with the “occupation” data of the user is also one of the procedures for determining the importance of knowledge.

[0043]

[Table 5] The knowledge importance determining unit 16 includes an argument called M-Result, which is a result of comparing the “field” data of knowledge with the “specialization” data of the user, and an A-Result,
It has an argument to store the result of comparing the “fitness” data with the “occupation” data, and a place to calculate the importance of “value”. The initial value of importance is 0. The knowledge importance judging unit 16 also calculates k in order to capture “field” data of knowledge.
An argument of -box is a d-box for capturing "fitness" data, a U-BOX for capturing user "specialty" data, and a J-BOD for "professional" data.
X, I-BOX for "interest" data, "English history"
For data, it has an argument called C-BOX.

The data of the knowledge to be subjected to the importance determination processing is fetched into these arguments, respectively, and is compared with the similarly fetched data of the user according to the rule of FIG.
The result is put into M-Result or A-Result. And M-Result, A-Result
The importance is calculated in the value according to the value inside.

This time, the knowledge numbers 121, 122, 1
The importance of the 23 knowledge is calculated. The state of the processing will now be described with reference to the flowcharts shown in FIGS. FIG. 10 shows a process for obtaining the value of M-Result, FIG. 11 shows a process for obtaining the value of A-Result,
FIG. 12 is a flowchart of a process of calculating importance from the values of M-Result and A-Result.

First, a process for calculating the importance of the knowledge of the knowledge number 121 will be described.

The knowledge importance determining section 16 determines that U-BOX = physical system, J-BOX = 3, I-BOX = nil (no data), C-BOX = 3, k-box = general, d-box
= 2, and put data in each argument. Processing is performed using these values and the rules in FIG.

First, processing for obtaining the value of M-Result is performed. A check is made as to whether the value of k-box is "general". In this case, since it is Yes, M-Result
Is set as the value of S1, and the process of obtaining the value of M-Result ends. Next, the contents of the J-BOX and d-box are compared to obtain the value of A-Result.
In this case, since the data of the J-BOX is larger than the data of the d-box, the data value of the d-box, that is, 2 is written to the A-Result. And M-Resul
The importance is calculated based on the values of t and A-Result. First, since the data of the M-Result is S1, 1 is added to the importance. Next, since data exists in the A-Result, 1 is further added, and the importance is set to 2.
When the data of the C-BOX is compared with the data of the A-Result, the data in the C-BOX is larger.
This indicates that there is a high possibility that the knowledge number 121 has already been learned based on the user's English history. Therefore, 0.5 is subtracted from the importance, and the importance of the knowledge of the knowledge number 121 is determined to be 1.5.

The importance of the knowledge of the knowledge number 122 is calculated in the same flow as the above processing. In the case of the knowledge number 122, k
-Box = commercial, d-box = 4: 6.

In this case, since the data of the k-box is not “general”, the field data in the k-box is converted into the user special data with reference to the field / special correspondence table in Table 4. Therefore, the data of k-box is as follows: "Faculty of Arts, Commerce, Economics,
..., sales, ... ". There is no field of "chemistry" which is the same as the U-BOX data. Then, next, look at the data in the I-BOX to check the user's interest.
Therefore, M-Result ends with nil.
As for the A-Result, since the data of the J-BOX is smaller than the data in the d-box, the process ends with nil. Thus, M-Resul
Since both t and A-Result are nil, knowledge number 12
The importance of knowledge 2 is 0.

The data of the knowledge number 123 is k-box =
Chemistry, d-box = 3. "Chemistry" in k-box
Is converted, the same "physical system" as the U-BOX data is found therein. Therefore, S2 is written in the M-Result. Next, the d-box data and the J-BOX
Comparing the data of A-Res
3 is inserted as the data of the ult. M-Resul
Since t is S2, 2 is added to the importance, and A-Resul
Since t has data, 1 is further added, and the importance becomes 3. After this, C-BOX and A-Result
Are compared, but since they have the same value, the significance of the knowledge number 123 is eventually 3.

The importance determined in this way is determined in step 3
8 is registered as importance information 102. The knowledge number is also registered as knowledge number information 103 in step 39.

In step 40, the knowledge importance determination unit 16 sends the user information 101, the importance information 102 of the knowledge whose importance is not 0, and the knowledge number information 103 to the screen component selection unit 17 together. The screen component selection unit 17
Information of knowledge number 121-importance 1.5 and knowledge number 123-importance 3 and user information 101 are received.

The screen component selection unit 17 determines in step 41
Then, data relating to the component candidates used in the knowledge presentation screen is extracted from the component information database 13, and in step 42, a component element candidate table is created using the extracted data. Then, in the next step 43, the component to be used is selected from the component candidate table according to the component selection rule. In step 44, the number of the selected component is registered as the use element information 104.

Table 6 shows an example of data in the component information database 13 referred to in step 41 and step 43
FIG. 13 shows an example of the component selection rule referred to in FIG.

[0056]

[Table 6] In the component information database 13, one data array is prepared for data of one component. The data array contains the data array name, knowledge number, component number,
Difficulty is recorded. “Difficulty” indicates the rank of the “substantial academic ability” to which the component of the number is suitable.
The first alphabet of the component number data indicates the type of component information. “T ****” is a sentence, “P ****” is a photograph or illustration, “V ****”
Indicates a moving image such as a video.

The screen component selection section 17 has the structure of a component candidate table as illustrated in FIG. In the first to fourth terms of this structure, data on components that can be used for presenting knowledge to be learned is fetched from the component information database 13. From the fifth item to the seventh item, a knowledge number in which the component has been used in the previous learning is entered from the second use. This is entered based on the learned knowledge data, the presentation use element data, and the presentation use rule data in the user information 101. Therefore, the candidate table becomes as shown in Table 7 while repeatedly using this system.

[0058]

[Table 7] The screen component selection unit 17 has a structure of Tcan and Pcan. Both are for recording data on constituent elements of selection candidates, and Tcan contains data on sentence information candidates, and Pcan contains data on image information candidates such as photographs, illustrations and videos. Tcan and P
can has a structure in which the knowledge number, the component number, the difficulty level, and the usage level are entered in that order.

Now, the importance information 102 and the knowledge number information 10 set in the knowledge importance determination section 16 will be described.
3, and a process of determining a component for expressing knowledge using the user information 101, Table 6, FIG. 13, and the like.

First, processing is performed on the knowledge of the knowledge number 121. The screen component selection unit 17 looks up the knowledge number item in the component information database 13 and registers data of an array having the same value as the knowledge number 121 to be processed this time in the candidate table. In addition, by looking at the learned knowledge item in the user information 101, it is checked whether there is data of the number 121. However, since this time the user uses for the first time, there is no learned knowledge, and the candidate table is as shown in Table 8.

[0061]

[Table 8] In the case of the knowledge of the knowledge number 121, the importance is 1.5, and therefore, the rule 2 “present knowledge and example sentences” in the rule of FIG. 13 is applied. Specifically, a component number “T ****”, its knowledge number, difficulty level, and the number obtained by subtracting 4 from the number of elements in the array are extracted from the data in Table 8 as utilization. The use degree is set as described above because, as can be seen from Table 8, the number of items in the data array when there is no use record is four.

These data are stored as information on the selection candidate elements in the form of Tcan 1 = (121, T0100, 3, 0) Tcan 2 = (121, T0256, 1, 0) according to the Tcan structure.

According to the rule shown in FIG. 13, it is determined whether Tcan 1 or Tcan 2 is used. Rule 1
From 1, the actual academic ability is compared with the difficulty of Tcan 1 and Tcan 2. Since this user has a real academic ability of 3, Tcan 1
Is more difficult, so Tcan 1 will be used.

The component number T0100 selected in this way is registered as use element information 104 in step 44.

Similar processing is performed on the knowledge of the knowledge number 123. A table such as Table 9 is created from the component information database 13 based on the knowledge number.

[0066]

[Table 9] Based on the importance of the knowledge, rule 3 “presented by knowledge, example sentence, and image” in the rule of FIG. 13 is applied, and from Table 9, Tcan 1 = (123, T0298,3,0) Tcan 2 = (123 , T0511, 3, 0) Pcan 1 = (123, P0272, 1, 0) Pcan 2 = (123, P0301, 4, 0) Pcan 3 = (123, P0314, 2, 0) Pcan 4 = (123, V1682) , 4: 5: 6,0).

The result T of the application of the remaining rules in FIG.
Can 1 and Pcan 2 are selected, and T0298 and P0301 are registered as use element information 104 for presenting the knowledge of the knowledge number 123. Registered usage element information 1
Reference numeral 04 denotes the screen composition unit 18 in step 45 together with the user information 101, the importance information 102, and the knowledge number information 103.
Sent to

The screen composition section 18 has a screen design table 105 as shown in FIG. 15, and applies the presentation rules in the presentation rule database 14 according to the importance of each presentation object knowledge. The screen is configured by determining the data of the items in the table.

The value of the screen design table 105 is determined in step 46, and the completed table is sent to the output unit 19 in step 47.

The presentation rule database 14 stores presentation rules relating to the configuration when a plurality of pieces of knowledge are arranged on the same screen, the arrangement method of the components, and the like. FIG. 16 shows an example of the presentation rule data. There are two types of presentation rules: regular rules and selection rules. Common rules are used to present all knowledge. The selection rule determines whether it is applied according to the importance value or other conditions. The selection rules include S1, K1,
A symbol such as HH2 is attached. When a selection rule is selected for presenting one piece of knowledge, a plurality of rules having the same alphabetic part of a symbol are not used. That is,
Only one of the rules with the same alphabetic part of the symbol is to be selected. When there are a plurality of executable statements for one conditional clause and there is no special condition for selection, there is a case where one executable statement among the plurality of executable statements is selected at random.

The screen composition unit 18 receives the information of the knowledge number 121-importance 1.5-component number T0100, knowledge number 123-importance 3-component number T0298: P0301 from the screen component selection unit 17. User information 1
01 was received.

The process of selecting the rule for knowledge of the knowledge number 121 will be described with reference to the flowchart shown in FIG.

Of the rule data, the common rule is applied to the presentation of any knowledge. First, the screen configuration is determined by applying A1. To select the presentation screen configuration, a random number generation device included in the screen configuration unit 18 generates a random number, divides the number by the number of candidates, and if the remainder is 1 (A) or 2 (A ),..., 5 is performed as (f). This time, since the number of candidates is six and the random number is 11, (f) is selected as the presentation screen configuration. And A
By applying 2, a standard value that is predetermined as a value of a size representing knowledge or an example sentence is set.

Next, the setting is made according to the selection rule according to the information determined by the application of the regular rule and the importance information.

Since (f) is selected as a result of the application of A1, it is necessary to select two more pieces of knowledge to be presented on the same screen. In this case, knowledge is selected based on the same screen presentation knowledge selection rule (illustrated in FIG. 18) existing in the component database 14. From the knowledge database 12, the knowledge number of the knowledge that satisfies the conditions of the field and the importance is extracted. Here, if more than the required number of knowledge numbers are taken out, a random number is generated as in A1, and the knowledge to be used is determined by the remainder obtained by dividing the random number by the number of candidates.

As a result, this time, knowledge number 503-knowledge of importance level 3 and knowledge number 88-knowledge of importance level 2.5 were selected.

Next, since the importance of the knowledge number 121 is 1.5, the process proceeds to the right side of the flow chart of FIG. 17 to check the rules thereunder. KI1 is applied according to the importance of the knowledge number 503 selected earlier, and the knowledge of the knowledge number 503 is determined to be located at one position on the screen. Since the importance of the knowledge of the knowledge number 88 is 2.5, the position of the knowledge number 88 is determined first according to KF1. Knowledge number 8
Since the position of 8 is determined to be 3, the position of the knowledge number 121 is determined to be 2.

Next, the presence or absence of an image such as an illustration or a video is determined based on whether the importance is 2 or more. If it is 2 or more, the size of the image to be displayed is determined. Since it is 1.5, it is concluded that no selection is necessary.

FIG. 19 shows an example created as described above.
Screen design table 105 for knowledge number 121 shown in FIG.
It is.

The rule for knowledge of knowledge number 123 is selected in the same procedure.

First, the common rules are applied. The screen configuration was determined to be (A) by applying A1. Therefore, it is not necessary to select the same screen configuration knowledge in the selection rule check, and the selection rule on the left side of the flowchart is examined. First, selection of S1 or S2 is performed. A random number is generated, and if it is odd, S1 is selected, and if it is even, S2 is selected. This time, S1 was selected. Next, H1 is selected and the rule rule selection is completed, and the screen design table 105 for the knowledge number 123 becomes as shown in FIG.

In step 47, the screen design table 105 is sent to the output unit 19. The output unit 19 extracts knowledge from the knowledge database 12 in step 48, and extracts and prepares components from the component database 15 in step 49. Incidentally, the component database 1
5 stores data in the following format for each type of data. The text data itself is stored together with the component number. Data of photographs and illustrations are stored individually as files, and the component numbers and the file numbers are stored together. Video data is L
D and videotape, and the frame number at the beginning and the frame number at the end of one scene are stored together with the component numbers. This frame number is passed to an LD or video player, and the player prepares a scene to be presented on the screen. In step 50, the prepared knowledge and constituent elements are arranged based on the received screen design table 105 and the basic element arrangement basic rules possessed therein, and the screen is presented. FIG. 22 shows an example of the component arrangement basic rule.

FIGS. 22 and 23 show examples of screens presented by the above series of processing. FIG. 22 shows the knowledge number 12
2 is a screen prepared to present the knowledge of FIG.
Reference numeral 3 denotes a screen for presenting the knowledge of the knowledge number 123.

The screen composing section 18 registers the constituent elements used for presentation and the number of the presentation rule in the user information 101 in step 51, and then registers in step 52
Sends the user information 101 to the user information database 11.

The user information database 11 stores the received user information in step 53 in the form illustrated in FIG. 24 so that the same knowledge can be presented on the same screen at the next review. . << Embodiment 2 >> Next, a description will be given of a change in a data transmission procedure between the components of the present apparatus in the second and subsequent uses.

The data transmission procedure in the user information input unit 10, the screen component selection unit 17, and the screen configuration unit 18 is different from that at the first use.

In the user information input section 10, when the user inputs a name, data in the user information database 11 is searched by the user name, and the remaining data in the user information 101 is searched using the result. Register items automatically. The user checks the registered data and corrects it if necessary.

The screen component selection unit 17 determines whether the knowledge to be processed is knowledge that has been learned before, by comparing the knowledge number information 103 with the data of the “learned knowledge” item of the user information 101. Are collated. If they are the same, processing is performed to create the screen design table 105 using the components and presentation rules recorded in the user information 101. By this processing, when the same user learns the same knowledge in the same situation, the presentation is always made with the same screen configuration. Further, when the component candidate table is created by the screen component selecting section 17, the data of the “presentation usage element” item in the user information 101 and the data of the “component element number” item of the candidate table are compared. .
If they are the same, the knowledge number recorded in “learned knowledge” in the user information 101 is written to the “use record” item in the data array of the candidate table. By this processing, the usage history of each component of the candidate table is recorded, and is used as one of the judgment factors when the component selection rule is applied.

Now, a case where the user A tries to use the present apparatus again will be described with reference to the flowcharts of FIGS.

The user information input unit 10 presents a user information input screen as shown in FIG. 2 in step 31 in the same manner as in the first embodiment, and urges the user information 101 to be input.

However, this time, when the user A inputs a name, in a step 31, the user information database 11
, The data on the user A is searched by the user name. The remaining items on the user information input screen are automatically set using the obtained data. So,
The user confirms the presented data, and corrects any errors or data to be changed. Note that what is presented to the user here is the same data as in the first embodiment, such as “name”, “age”, “occupation”, “professional”, “English history”, and “interest”. 24 also has information on the learned knowledge, the presentation use element, and the presentation use rule shown in FIG.

Using the data set in this way, the processing from step 32 onward proceeds. However, the processing up to step 40 is the same as that in the first embodiment, and can be easily analogized. Omitted.

In step 40, the screen component selection unit 17 sends the user information 10 from the knowledge importance determination unit 16.
1. Receives importance information 102 and knowledge number information 103.

Here, a case will be described as an example where the same information as knowledge number 121-importance 1.5 is received as in the first embodiment. First, the screen component selection unit 17 executes step 6
In step 1, the knowledge number 121 is compared with the "learned knowledge" data of the user information 101. In the “learned knowledge” item of FIG. 24, 121 and 123 are recorded. Then, in order to present the knowledge of the knowledge number 121, in step 63, the data of the “presentation use element” item = T0100 recorded in the user information 101 of FIG. = A1, A2, A3 (f), A
The screen design table 105 is set by applying S0, KI1, and KF1.

Next, it is assumed that the screen component selection unit 17 has received information of knowledge number 200-importance level 2.

Since the knowledge number 200 is not registered in the user information 101, the process proceeds from step 61 to step 41 and step 62. In step 41, the data of the component that is a selection candidate is referred to, and in step 62, the "learned knowledge" data of the user information 101 is referred to. Then, in step 42, first, a candidate table exemplified in Table 10 is created, and the “component number” data in Table 10 is compared with the “presentation use element” data in the user information 101.

[0097]

[Table 10] Here, since there is T0100, the data “121” of the “learned knowledge” item of the user information 101 is recorded in the “use record 1” item of the array. In addition, “123” is also added to the “Usage record 1” item in the array where P0301 is recorded.
Is recorded.

Table 11 shows the completed candidate table. Using this candidate table, a screen is designed for the knowledge presentation of knowledge number 200.

[0099]

[Table 11] The subsequent processing is the same as that in the first embodiment.
Since it can be easily analogized, the description is omitted.

The following experiment was conducted for the purpose of examining the influence of the laid out information on human perception. Newspaper was taken up as the laid out information.
There are two types of newspapers prepared for the experiment: (1) newspapers composed of economic, political, international and social aspects, and (2) newspapers composed of sports, political, international and social aspects. Yes, the subject was instructed to search for economics from (1) and sports from (2).

On the newspaper side, the sports side is laid out differently from other social and economic aspects due to features such as a large number of non-text areas such as the number of photographs, photographs, headings, and tables.

As a result of the experiment, 2.6 seconds per side when searching for the economic side, and 1.0 seconds per side when searching for the sports side.
It turned out that 9 seconds were required. From this result, it was found that the type of the paper surface can be determined by the characteristics of the paper surface configuration such as “the amount of image data”.

Therefore, retrieval of a presentation surface having a characteristic is performed more quickly than retrieval of a presentation surface that is not otherwise. If there is some regularity in the characteristic of the presentation surface, what is the surface relating to the presentation surface? It can also be determined.

In addition, when the newspaper layout and the judgment of the importance of the article were examined, an important article with a large headline, an important article with a large photo, and an article at the bottom and center of the paper In addition, the articles at the top end were more important than others, and made impressions.

From the above results, it was found that the importance can be determined by the characteristics of the presentation surface of the knowledge, that the importance has a plurality of ranks, and that there are a plurality of means for determining the importance. This indicates that there are a plurality of means for allowing the user to judge the importance of knowledge, and that the number of judgment criteria and the rank of importance can be further increased by combining them. It also shows that it is possible to express the same degree of importance by different presentation means.
