Abstract

An electronic teaching material capable of easily dynamically reconfiguring and rearranging display objects on a screen can be created. By applying the priority control condition within a range that does not deviate from the duplication avoidance condition, the group object in the lower hierarchy can be set to the individual processing mode while the editing target is kept unique, or placed in the same group object. A plurality of group objects are set to the individual processing mode at the same time. When other group objects included in one group object are in individual processing mode, group objects that are included in one group object, do not include other group objects, and are not included in other group objects When switching to the individual processing mode, the duplication avoidance condition is prioritized over the priority control condition, and the group in the highest hierarchy is shifted to the individual processing mode without departing from the duplication avoidance condition.

Description

  The present invention relates to a program using object technology.

  In recent years, various educational methods have been attempted in educational institutions that conduct natural language education in order to improve the understanding of learners. As one of such teaching methods, it is not uncommon to see so-called e-learning using a computer as an auxiliary teaching material at the time of language education against the background of the spread of personal computers (PCs) in the field of language education.

Learners' interest in language acquisition has also increased, and e-learning is not limited to specialized environments such as educational institutions as an application range in the field of language education, and electronic teaching materials can be easily obtained for general home learning. ing.
Such electronic teaching materials are also becoming more multifunctional in order to increase learning motivation and to differentiate from other companies' products (for example, see Patent Document 1). According to the electronic learning system disclosed in Patent Document 1, electronic learning materials can be edited by adding original information such as images and sounds prepared by the learner himself.

JP 2006-308815 A

There are two main types of software used for e-learning: one used by teachers to present learning content to students, and one used by students themselves for use in learning. .
Typical software used for the former teacher application includes slide creation software represented by PowerPoint (registered trademark).
This kind of slide creation software can display characters and images prepared in advance at any time and place them at any position. Time and effort can be saved.
In addition, since re-editing of the contents is also editing of the image and text data on the computer, editing work is compared to the case where the printed contents are distributed or the learning contents are shown using an OHP (OverHead Projector) sheet or the like. Can save you time.

There are various kinds of teaching material software used for the latter purpose for learners, but what is desired to be developed in the future is teaching material software having an interactive function unique to electronic teaching materials.
The interactive function is not a simple browsing function, but a function that a display object on the software moves, makes a correct / incorrect determination, and notifies the determination result in accordance with a learner's operation. With such a function, in addition to the merit that the learner can learn without using paper or a pen, there is a merit that the answer result to the question can be confirmed on the spot.

As described above, e-learning using software is useful, but many problems remain at present. In general, the above slide creation software does not support dynamic changes such as the configuration and arrangement of display objects when presenting information.
Here, “dynamic change” refers to making a change to a configuration or arrangement according to the situation on the spot, which is different from the configuration / arrangement as prepared in advance.

In addition, from this, if the materials created using the slide creation software are handed over to the learner, they will simply be used as educational materials for viewing purposes, and learning using interactive functions Does not correspond to
Thus, the development of e-learning requires a mechanism that can flexibly cope with changes in the configuration and arrangement of display objects such as characters and images.

Many softwares have a “grouping” function as a function of composing display objects such as characters and images.
The grouping is normally performed by a method of selecting and specifying a display object such as a plurality of characters and images and generating a group object composed of the plurality of objects specified and specified.
By using this grouping function, it is possible to generate objects composed of multiple display objects, and to perform change processing such as position change and color change for multiple objects at once. It becomes.

However, in general, existing software having the grouping function as described above cannot easily reconfigure groups.
Normally, to reconfigure an object such as adding or removing an object from a group or changing the arrangement within a group, cancel the grouping, select an object that you want to be a member of the group, and then group again. It is necessary to follow the procedure.

Also, some existing software, such as Illustrator (registered trademark), has a function that allows reconfiguration without releasing grouping. Usually, in these software, a certain group object is used. When transitioning to a reconfigurable state, the entire screen is switched to a mode for reconfiguring the group object, and in that state, other objects cannot be operated.
For this reason, these software cannot keep multiple group objects in a reconfigurable state at the same time, and each time a different group object is reconfigured, the reconfiguration mode and the normal mode are not used. It is necessary to follow the procedure of switching.

Due to the above technical limitations, it is very difficult to change the composition dynamically when presenting the electronic teaching materials created by the teacher to the learner. There will be restrictions.
In addition, it is difficult for a learner who has received the electronic learning material to learn using the interactive functions inherent in the electronic learning material. I can't make full use of it.

The present invention has been made in view of the above problems, and provides a mechanism that enables creation of an electronic teaching material that can easily reconfigure and rearrange display objects on a screen, and The purpose is to broaden the range of education and learning using electronic teaching materials by providing a mechanism that enables the learners to use interactive functions when the electronic teaching materials are delivered to learners. To do.

[First invention]
Therefore, in order to solve the above problem, a program according to the first invention of the present application is:
A procedure for displaying, arranging and rearranging display objects composed of characters, images, etc .;
Creating a group object by grouping an arbitrary number of the display objects, and setting the arbitrary number of display objects as subordinate objects of the group object;
A grouping of one group object and another display object or other group object, thereby making the one group object a subordinate object of a higher-order group object;
A procedure for performing batch processing on all subordinate objects of the group object while fixing the relative positional relationship between the subordinate objects;
In a program that causes a computer to execute

For any group object in any hierarchy, the processing mode, the batch processing mode that can execute batch processing while fixing the relative positional relationship between the subordinate objects of this group object, and the fixed state of the relative positional relationship Mode switching procedure to switch to individual processing mode that can execute individual processing for any subordinate object by canceling
Assigning a unique determination area to the group object;
Have

When a group object is held in the individual processing mode,
(1) When a display object or group object that is not a subordinate object of this arbitrary group object is dragged and moved from the outside of the judgment area to the inside of the judgment area, the dropped display object or group Add the object as a subordinate object of the arbitrary group object,
(2) When the subordinate object of this arbitrary group object is dragged out of the determination area and dropped outside the determination area, the dropped subordinate object is excluded from the arbitrary group object. And
(3) When the subordinate object of the arbitrary group object is dragged and dropped in the determination area, the position of the dropped subordinate object in the arbitrary group object is updated,
In addition, the processing mode can be held for each group object,

Furthermore, a procedure for assigning an identification character string for uniquely identifying any display object or group object,
A procedure for specifying a determination condition when comparing the identification character string given to the group object and the identification character string given to the subordinate object of the group object;
Have

When a string matching operation is performed,
Acquire an identification character string of the group object, and an identification character string assigned to each subordinate object of the group object,
Check whether the acquired identification character string of the group object and the acquired identification character string of the subordinate object match under the specified determination condition,
The configuration is such that the verification result (match or mismatch) is notified.

As described above, in some conventional software, when group objects are organized (addition, exclusion, rearrangement, etc.), the group relation must be released and all subordinate objects of the group object must be separated. Could not be added or excluded. In addition, this type of software also requires regrouping to reconfigure the group objects after the subordinate object addition / exclusion operations are completed.
However, according to the program according to the first invention, the concept of the determination area is introduced to the group object, and the display object moved from the outside of the determination area to the inside is added as a subordinate object of the group object. Subordinate objects that have moved out of the range are excluded from the group object.
Therefore, when the group objects are organized, the operation procedure corresponding to the above-described group cancellation or regrouping is omitted, and the group organization can be easily performed with a smaller number of operations.

In addition, as described above, some conventional software can reconfigure subordinate objects without canceling the group. In the case of these software, multiple group objects can be reconfigured simultaneously. Each time a different group object is reconfigured, the reconfiguration mode (equivalent to “individual processing mode”) and normal mode (equivalent to “batch processing mode”) It is necessary to follow the procedure of switching.
However, according to the program according to the first invention, since it is possible to maintain the individual processing mode for each group object, such a switching procedure becomes unnecessary, and when reconfiguring a plurality of group objects sequentially The operation procedure can be simplified.

According to the program of the first invention, whether or not the identification character string of the group object matches the identification character string of the subordinate object under the specified determination condition when the character string collating operation is performed. Is matched.
In this way, it is possible to set answers to various questions such as a hole filling problem, a selection problem, and a rearrangement problem created by the teaching material creator on this software.
Also, the learner can answer these various questions by operating the objects on the screen, and can confirm the correctness immediately after answering.

The contents of the question can be changed by changing the determination condition to be specified. The determination conditions include (1) complete match, (2) random order match, and (3) partial match.
Furthermore, when the teaching material creator creates a question, it is also possible to give a question whose answer is an image or sound by assigning an identification character string to an object composed of an image or sound.

[Second invention]
In order to solve the above problem, a program according to the second invention of the present application is:
A procedure for displaying, arranging and rearranging display objects composed of characters, images, etc .;
Creating a group object by grouping an arbitrary number of the display objects, and setting the arbitrary number of display objects as subordinate objects of the group object;
A grouping of one group object and another display object or other group object, thereby making the one group object a subordinate object of a higher-order group object;
A procedure for performing batch processing on all subordinate objects of the group object while fixing the relative positional relationship between the subordinate objects;
In a program that causes a computer to execute

For any group object in any hierarchy, the processing mode, the batch processing mode that can execute batch processing while fixing the relative positional relationship between the subordinate objects of this group object, and the fixed state of the relative positional relationship Mode switching procedure to switch to individual processing mode that can execute individual processing for any subordinate object by canceling
Assigning a unique determination area to the group object;
Have

When a group object is held in the individual processing mode,
(1) When a display object or group object that is not a subordinate object of this arbitrary group object is dragged and moved from the outside of the judgment area to the inside of the judgment area, the dropped display object or group Add the object as a subordinate object of the arbitrary group object,
(2) When the subordinate object of this arbitrary group object is dragged out of the determination area and dropped outside the determination area, the dropped subordinate object is excluded from the arbitrary group object. And
(3) When the subordinate object of the arbitrary group object is dragged and dropped in the determination area, the position of the dropped subordinate object in the arbitrary group object is updated,
In addition, the processing mode can be held for each group object,

In addition, for multi-level group objects such that the group object has other group objects as subordinate objects, priority control conditions stipulating that the group object is shifted to the individual processing mode in order from the upper level group object,
In addition, in order to uniquely determine the group object to be edited, (A) the group object that shifts to the individual processing mode and the group object that includes this group object must not enter the individual processing mode at the same time. (B) shift to the individual processing mode. The group object included in the group object and the group object included in the group object do not simultaneously enter the individual processing mode.
Have

By applying the priority control condition within a range that does not deviate from the duplication avoidance condition, the group object in the lower hierarchy can be set to the individual processing mode while the edit target is kept unique, or a plurality of objects arranged in the same group object can be set. Group objects can be in individual processing mode at the same time,

When other group objects included in one group object are in individual processing mode,
When switching a group object that is included in the one group object, does not include the other group object, and is not included in the other group object to the individual processing mode,
The configuration is such that the duplication avoidance condition is prioritized over the priority control condition, and the group in the highest hierarchy is shifted to the individual processing mode without departing from the duplication avoidance condition.

According to the program of the second invention, under a condition for avoiding duplication, when a certain group object shifts to the individual processing mode, all other group objects that are in a non-independent relationship (embedding relationship) with this group object are all. Changed to batch processing mode.
As a result, it is possible to prevent a plurality of group objects in a non-independent relationship (embedding relationship) from being simultaneously held in the individual processing mode.
Further, under the priority control condition, switching to the individual processing mode is performed preferentially from a higher-order group object.
As a result, even when there is a multiple structure in which a certain group object has other group objects as subordinate objects, it is possible to designate a group object in an arbitrary hierarchy as a processing mode change target.

Here, the “independent relationship” is a relationship in which there is no embedded relationship between one object and another object.
Specifically, when the inclusive relation of objects (group objects, subordinate objects) is represented by a tree structure (see FIG. 5), a third object other than both objects is reached before reaching one object from another object. This refers to a relationship that cannot be reached unless the direction (upward or downward) of following the tree through the tree is changed.
In the example of FIG. 5, it is necessary to change the direction of tracing the tree from the upward direction to the downward direction in the group object G-31 while leaving the subordinate object G-11 to reach the subordinate object G-21. . Therefore, there is no embedding relationship between the subordinate objects G-11 and G-21, and they are independent. In this case, both can hold the individual processing mode.

In the present invention, the concept of “non-independent relationship” is used as a concept opposite to “independent relationship”. “Non-independent relationship” means that an embedded relationship exists between an object and another object.
Specifically, it refers to a relationship in which the direction (upward direction or downward direction) in which the tree is traced does not change before reaching from one object to another object through the shortest path.
In the example of FIG. 5, while leaving the subordinate object G-11 and arriving at the subordinate object G-22 or the group object G-31, it is not necessary to change the direction in which the tree is traced in the upward direction. Therefore, there is an embedded relationship between the subordinate object G-11 and the objects G-22 and G-31, and they are non-independent. In this case, both cannot hold the individual processing mode.

According to the program of the second invention, even when a group object has multiple hierarchies, it is possible to make a group object in an arbitrary hierarchy editable, and a plurality of independent group objects At the same time, it can be kept in an editable state.
Thereby, the procedure at the time of the group object reconfiguration operation is reduced, and the operation efficiency at the time of changing the display configuration on the screen is improved.

[Third invention]
The program according to the third invention of the present application is a program according to the first or second invention,
The method further includes a step of automatically rearranging the subordinate objects of the group object at a predetermined interval when the subordinate objects are added or removed from the group object or the position of the subordinate object is changed in the determination area.
According to each program according to the first invention or the second invention described above, the group configuration of the group object is immediately changed. According to the third invention, the subordinate objects after the configuration change can be automatically laid out, Since the user can move while maintaining this state, the user can omit an operation for arranging the layout.

[Fourth Invention]
The program according to the fourth invention of the present application is a program according to the first, second, or third invention, for learners with restricted display objects or group objects that can be operated, and destinations to which these objects are moved. Usage environment and
The display object and the group object can be operated indefinitely, and a use environment for a teaching material creator capable of arbitrarily selecting a destination of the movement can be set.

In the program according to the present invention, the learning material creator gives the learning material created on the software to the learner, and the received learner can operate the learning material with a language education application. However, if there is no restriction on the data modification of the electronic teaching material, it is possible that the learner mistakenly changes or deletes the object in the electronic teaching material.
On the other hand, if any access to the display object by the learner is prohibited, interactive learning using the advantage of the electronic teaching material by operating the display object becomes impossible.
According to the program relating to the fourth invention, the usage environment for the teaching material creator who has been given the editing authority to create / modify the original electronic data, and the electronic data are limited to answering questions and confirming answers. It is possible to provide two different use environments, that is, a use environment for a learner who is given only the right to use for the purpose, and the above-mentioned problems can be solved.

In the use environment for the teaching material creator, it is desirable that the use environment for the learner and the usage environment for the teaching material creator can be switched.
This is because when the learning material creator himself / herself sets the use environment for the learner, it can be confirmed whether or not the program is operating as intended by the learning material creator in the environment.

[Fifth Invention]
In order to solve the above problem, a program according to a fifth invention of the present application is a program according to the fourth invention,
The display objects that can be operated in the use environment for learners are subordinate objects of the group object set to the individual processing mode,
The configuration is such that the movement destination of the object in the use environment for learners is a group object set to the individual processing mode.

[Sixth Invention]
In order to solve the above problem, a program according to the sixth invention of the present application is a program according to the fourth or fifth invention,
When a drag operation is performed by the user, the dragged original display object remains in its original position, and a duplicate drag mode is generated to generate an object having the same attribute as the display object at the drag destination.
The display object that can be operated in the environment for learners is a display object generated in the duplicate drag mode,
The configuration is such that the movement destination of the object in the use environment for learners is a group object set to the individual processing mode.

In the initial state (default), the objects that can be operated in the use environment for learners are limited to objects under the group object set in the individual processing mode, objects set in the duplicate drag mode, and the like.
The “duplicate drag mode” here means that when a drag operation is performed by the user, the original display object that has been dragged is left in its original position, and an object having the same attribute as this display object is dragged. This refers to the operation mode that is generated first.
In addition, in the use environment for learners, there are restrictions on the destination of the object to be moved. Specifically, the object can be moved only when it is added as a subordinate object of the group object G set to the individual processing mode.
Thereby, the operation by the learner is limited to the operation necessary for learning such as the answer to the question, and it is possible to prevent the screen configuration that forms the basis of the electronic teaching material data from being damaged by the operation by the learner.

Hereinafter, this content will be described in detail.

FIG. 1 is a block diagram illustrating an electrical configuration of the language education terminal 1 according to the first embodiment.
As shown in FIG. 1, the language education terminal 1 includes an output unit 14 such as a liquid crystal display (not shown) and an input unit 13 including a touch panel (not shown). The input unit 13 may have a gesture recognition function using an infrared sensor or the like.
The language education terminal 1 includes a control unit 11 including a CPU (central processing unit) that executes arbitrary arithmetic processing, a storage unit 12 including a hard disk drive (HDD), ROM, RAM, and the like, and various signals or The communication unit 15 includes a communication port (not shown) that forms an information input / output path.

The communication unit 15 is connected to a public communication line (not shown) such as the Internet or a mobile communication network, and performs various communications with other devices. As the communication unit 15, a network interface, a modem, or the like is used.
The terminal 1 is connected to a printer (not shown) via a predetermined interface such as a USB (Universal Serial Bus) connection terminal or the communication unit 15, and user data 122 created by the user by the language education application 121 is printed on a paper medium. May be printed out.
An example of the user data 122 is an electronic teaching material in which questions, answers to questions, explanations, explanatory diagrams, and the like are each configured by a display object D.

The control unit 11 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like, and an application program (for language education) stored in the ROM / storage unit 12. The application 121) is loaded into the RAM and executed, thereby realizing various logical means.
In the language education terminal 1, an object generation / deletion unit 111, an object editing unit 112, and a group management unit 113 are realized.

  The object generation / deletion unit 111 is a unit that generates or deletes an object. As illustrated in FIG. 2A, the object generation / deletion unit 111 includes an object generation unit 1111 and an object deletion unit 1112.

The object generation unit 1111 is a unit that generates a display object D (for example, see D-1 to D-5 in FIG. 4A) composed of characters, images, and the like according to the input content. When the terminal 1 includes a camera that captures an arbitrary subject, an image captured by the camera can be used as the display object D.
In the case where the object is character data, the object generation unit 1111 divides characters by a delimiter (for example, a blank symbol) inserted in the sentence when the character is input to the electronic teaching material (user data 122). The display objects D may be individually generated in units of columns.

In this example, the display object D generated by the object generation unit 1111 is managed using the display object information 123 (see FIG. 6).
The display object information 123 is information for designating a correspondence relationship between the display object ID assigned to the display object D and the attributes related to the display object D.
In the example of FIG. 6, in the display object information 123, the display object ID for individually identifying the display object D, the data type and data content of each display object D, and the attributes (position, size, Color).

Further, the object deleting unit 1112 shown in FIG. 2A is a unit that deletes the display object D designated by the user in response to the user's object deleting operation.
When the display object D is deleted, the object deletion unit 1112 deletes the registered content related to the display object D from the display object information 123 (FIG. 6).

  The object editing unit 112 shown in FIG. 1 is a unit that performs overall object editing processing. As shown in FIG. 2B, the object editing unit 112 includes a display position management unit 1121 and an attribute management unit 1122.

The display position management unit 1121 is a unit that displays, arranges, and rearranges the display object D.
The attribute management unit 1122 is a unit that manages the attribute of the object (group object G or display object D) based on the display object information 123 and the group object information 124.
Examples of this attribute include the size and angle of the display object D, the character color / background color, and the like. Further, the attribute management unit 1122 controls display / non-display switching of the object.
In this way, each user can perform highlighting by changing the color or size of each object so as to be easily understood by each user.

The group management unit 113 shown in FIG. 1 is a unit that performs overall management of the group object G.
As shown in FIG. 3, the group management unit 113 includes a grouping unit 1130, an automatic alignment switching unit 1133, an automatic alignment unit 1134, a mode switching unit 1135, a group editing unit 1136, a group release unit 1140, have.

Furthermore, in this example, the grouping means 1130 is subdivided into subordinate object organization means 1131 and area allocation means 1132 by function.
The subordinate object organizing means 1131 is a means for generating and configuring the group object G by generating the group object G and configuring any number of display objects D as subordinate objects of the group object G.
In the example of FIG. 4A, a group object G-22 having a display object D-3 and a group object G-11 as subordinate objects is configured. It is also possible to generate an empty group object that has no subordinate objects.

In this example, the group object G generated by the subordinate object organizing means 1131 is managed using the group object information 124 (see FIG. 7). The group object information 124 is information for designating a correspondence relationship between the group object ID assigned to the group object G and various information related to the subordinate objects of the group object G.
In the example of FIG. 7, in the group object information 124, a group object ID for individually identifying the group object G, a processing mode of each group object G, a subordinate object of each group object G, and an object of each subordinate object The type is associated.

The area allocation unit 1132 shown in FIG. 3 is a unit that allocates a unique determination area to the group object G.
In the present invention, the concept of a determination area unique to the group object G is used, and when the group object is in the individual processing mode, it is determined whether or not the object has been moved across the determination area. Objects are added / excluded.
Further, when the subordinate object of the object G is dragged in the determination area and dropped in the determination area, the position of the subordinate object is changed according to the position at the time of dropping.

The automatic alignment switching unit 1133 can switch the automatic alignment function of the automatic alignment unit 1134 on or off by a user's automatic alignment switching operation.
When the group object G (for example, see G-11 to G-31 in FIG. 4A) adds or excludes subordinate objects or changes the position in the determination area, the automatic alignment unit 1134 The subordinate objects of the object G are automatically rearranged at a predetermined interval.

The mode switching unit 1135 shown in FIG. 3 is a unit that switches the individual processing mode so as to satisfy the overlap avoidance condition and the priority control condition.
The designation of the group object G that shifts (switches) the processing mode to the individual processing mode is performed by a predetermined operation (for example, a long press via the touch panel) on the determination region of the object G.
In addition, the designation of the group object G that shifts (switches) the individual processing mode to the batch processing mode is performed by determining this object G with a predetermined operation (for example, a double tap via the touch panel) different from the transition to the individual processing mode.

The “duplication avoidance condition” refers to a condition for avoiding a plurality of group objects G that are not in an independent relationship (that is, in a non-independent relationship (embedding relationship)) simultaneously in an individual processing mode. .
Under the overlap avoidance condition, when a certain group object shifts to the individual mode, the group object in a non-independent relationship (embedding relationship) with this group object is changed to the collective mode to satisfy the overlap avoidance condition.

The technical significance of the duplicate avoidance condition is shown below.
As a specific example, in the example of FIG. 4A, the group object G-31 has a group object G-21 and a group object G-22 as subordinate objects, and the group object G-22 is a group object as a subordinate object. The group objects G-31, G-22, and G-11 have a non-independent relationship (embedding relationship).

Here, if the overlap avoidance condition is not imposed, a situation may occur in which a plurality of group objects among the group objects G-31, G-22, and G-11 are simultaneously set to the individual processing mode.
In the group object set to the individual processing mode, the user can individually operate the subordinate objects. For example, all of the group objects G-31, G-22, and G-11 are set to the individual processing mode. In the situation where the user's finger or mouse cursor is placed on the display object D-4, the object to be edited is (1) the subordinate object of the group object G-11. (2) G-11 (including subordinate objects D-4 and D-5 of G-11) that are subordinate objects of the group object G-21, or (3) Group object G- It is determined whether the object is G-22 (including G-22 subordinate objects D-3 and G-11). Can not.
For this reason, by imposing duplicate avoidance conditions that prevent multiple group objects that are in a non-independent relationship (embedding relationship) from being simultaneously held in the individual processing mode, the ambiguity in specifying the object to be edited is reduced. Can be excluded.

The “priority control condition” refers to a condition for determining a priority order when switching to the individual processing mode.
Under the priority control condition, the priority control condition is satisfied by preferentially switching from the higher-level group object G to the individual processing mode. As a result, even when there is a multiple structure in which a group object has another group object as a subordinate object, it is possible to appropriately designate a group object at an arbitrary hierarchy as a change target of the individual processing mode according to the priority order.
Note that the mode switching unit 1135 preferentially applies the overlap avoidance condition when both the overlap avoidance condition and the priority control condition are likely to be applied in a superimposed manner.

For example, in the example of FIG. 8A, all group objects are set to the batch processing mode.
In this state, when an operation for changing the processing mode of the group object G-22 to the individual processing mode is performed on the group object G-22, first, the processing mode of the group object G-31 is shifted to the individual processing mode. (See FIG. 8B).
This is whether priority is given to changing the group object G-31 in the hierarchy above the group object G-22 to the individual processing mode according to the priority processing mode.

When the group object G-22 is changed to the individual processing mode in a state where the group object G-31 is set to the individual processing mode as shown in FIG. 8B, the group object G-22 is operated. Is changed to the individual processing mode (see FIG. 8C).
At this time, the processing mode of the group object G-31 that is in a non-independent relationship (embedding relationship) with the group object G-22 is returned to the collective processing mode in accordance with the overlap avoidance condition (FIG. 8C).

In addition, when a transition operation to the individual processing mode is performed on the group object G-21 in this state, the processing mode of the group object G-21 is maintained while the processing mode of the group object G-22 is held in the individual processing mode. Is changed to the individual processing mode (see FIG. 8D).
In this case, if the priority control condition is satisfied, the processing mode of the group object G-31 at a higher level than the group object G-21 is changed. Both G31 are set to the individual processing mode, and the overlap avoidance condition is not satisfied.
In such a case, the overlap avoidance condition has priority. That is, the process for changing the group object G-31 to the individual processing mode is not performed, and the processing mode of the group object G-21 is changed to the individual processing mode.
As described above, the mode switching unit 1135 includes a unit that changes the processing mode of an arbitrary hierarchy while excluding the ambiguity of the designation of the edit target even in the group having the multiple structure.

In addition, since the mode switching unit 1135 in FIG. 3 can maintain the processing mode for each group object G as long as each group object is in an independent relationship, there is a group that can be reorganized on the screen. There can be multiple.
In the screen example of FIG. 9, since the group objects G-412 and G-414 are independent, they are simultaneously held in the individual processing mode. On the other hand, since the group objects G-411, G-413, and G-414 are in a non-independent relationship with each other, they are restricted by the overlap avoidance condition. Therefore, it can be seen that these objects G-411, G-413, and G-414 cannot be simultaneously held in the individual processing mode.

The group editing unit 1136 illustrated in FIG. 3 is a unit that executes addition / exclusion of subordinate objects with respect to the group object G, and rearrangement of subordinate objects within the determination area of the group object G.
The group editing unit 1136 is subdivided by function into subordinate object adding unit 1137, subordinate object excluding unit 1138, and subordinate object rearranging unit 1139.

  The subordinate object adding unit 1137, when an arbitrary group object G is held in the individual processing mode by the mode switching unit 1135, is an object that is not a subordinate object of the arbitrary group object G (hereinafter referred to as “non-subordinate object” as appropriate). Is dropped in the determination area, the dropped object is added as a subordinate object of the arbitrary group object G.

  The subordinate object excluding means 1138, when an arbitrary group object G is held in the individual processing mode by the mode switching means 1134, when the subordinate object of the arbitrary group object G is dropped outside the determination area, The dropped subordinate object is excluded from the arbitrary group object G.

  The subordinate object rearranging unit 1139 drags and drops the subordinate object of the arbitrary group object G in the determination area when the arbitrary group object G is held in the individual processing mode by the mode switching unit 1134. In this case, the subordinate objects are rearranged in the determination area of the group object G.

In the program according to the present embodiment, it is possible to organize the group object G while maintaining grouping, and therefore it is possible to omit an operation procedure corresponding to group release or regrouping that has been conventionally required when grouping.
For this reason, group organization can be easily performed with a smaller number of operations, and characteristic technical ideas unique to the present invention that have not been found in conventional software have been elaborated.

  The group cancellation unit 1140 is a unit that cancels the group relationship between the subordinate objects in the group object G formed by the subordinate object organization unit 1131.

Next, the operation of the language education terminal 1 according to the present embodiment will be described.
Here, a plurality of display objects D are generated by a user's operation, a group object G is formed by grouping the plurality of display objects D, the automatic alignment mode is switched, and subordinate objects of the group object G are added / An operation in which exclusion / relocation is sequentially performed will be described.

First, as shown in FIG. 10, the object generation unit 1111 generates a display object D composed of characters, images, and the like in accordance with the input contents from the user (step S11). In the example shown in FIG. 11A, a plurality of display objects D-51 and D-52 are generated by a user input operation.
Note that the attribute management unit 1122 adds information related to the newly formed display objects D-51 and D-52 to the display object information 123.

When the group formation operation is performed by the user, a group object G-50 (see FIG. 11B) having the display objects D-51 and D-52 selected and specified as subordinate objects is formed (step S12).
At this time, the attribute management unit 1122 adds information related to the newly formed group object G-50 to the group object information 124. In this example, as shown in FIG. 11B, when the group object G-50 is formed, the processing mode is set to the batch processing mode.

  Subsequently, a unique determination area is automatically allocated to the group object G-50 just formed by the area allocation means 1132 (step S13).

When the user performs a switching operation to turn the automatic alignment function from off to on, the automatic alignment switching unit 1133 switches the group object G-50 to the automatic alignment mode.
Accordingly, the automatic alignment unit 1134 automatically aligns the subordinate objects of the group object G-50 at equal intervals (step S14).

  When the user further performs a group editing mode change operation, the mode switching unit 1135 shifts the group object G-50 to the individual processing mode (see FIG. 11C) (step S15).

Thereafter, when the non-subordinate object is dropped in the determination area of the group object G by the user, the subordinate object adding unit 1137 adds the dropped object as a subordinate object of the group object G (step S16), and further automatically The alignment means 1134 automatically aligns all subordinate objects including the dropped object according to the position at the time of dropping.
In the example of FIG. 11D, the display object D-53, which is a non-subordinate object, is dropped by the user in the determination area of the group object G-50, so that the object D-53 becomes the group object G-50. Added as a subordinate object. Then, all the subordinate objects D-51 to D-53 including the dropped object D-53 are automatically aligned.

Thereafter, when the subordinate object of the group object G is dropped outside the determination area by the user, the dropped object is excluded from the subordinate objects of the group object G (step S17), and the automatic alignment unit 1134 Rearrange all subordinate objects.
In the example of FIG. 11E, when the subordinate object D-51 of the group object G-50 is dropped outside the determination area by the user, the object D-51 is excluded from the subordinate objects of the group object G-50. Is done. Thereafter, the remaining all subordinate objects D-52 and D-53 are rearranged.

Subsequently, when the position of the subordinate object of the group object G-50 (subordinate objects D-52 and D-53 in FIG. 11F) is changed within the determination area by the user rearrangement operation (step S18). Depending on the position after the change, all subordinate objects D-52 and D-53 are automatically rearranged. At this time, the display position management unit 1121 updates the position information regarding the subordinate object whose position has been changed.
In the example of FIG. 11F, in the group object G-50, the position of the subordinate objects D-52 and D-53 in the arrangement state of FIG. In the determination area of the group object G-50, the left and right are interchanged.
Note that the area allocation unit 1132 illustrated in FIG. 3 automatically adjusts the size of the determination area according to the arrangement state of the subordinate objects after the rearrangement when the subordinate objects of the group object G are added or excluded. It may be a thing.

As described above, according to the program according to the first embodiment, the concept of the determination area is introduced into the group object G, and the display object D moved from the outside of the determination area to the area is subordinate to the group object G. It is possible to exclude from the group object G the subordinate objects that have moved in the area and moved out of the area.
In addition, the above operation can be performed on an object in an arbitrary hierarchy, and the above operation can be performed on a plurality of objects without performing a switching operation.
Therefore, when the group object G is organized, an operation procedure corresponding to group cancellation or regrouping is omitted, and the group organization can be easily performed with a smaller number of operations.

  Also, unlike blackboards and paper media, editing electronic data compatible with e-learning makes it easy to add and delete information without leaving traces, so that knowledge organization and text required for language learning Management and notebook creation can be performed efficiently.

In addition, by introducing the program (application) according to the present embodiment into an arbitrary multi-function electronic apparatus, various characteristic functions of the present invention can be added, and the language education terminal 1 can be configured.
Further, according to the present embodiment, the language education terminal 1 can be configured inexpensively, simply and in a short time, simply by installing a dedicated application in the multi-function electronic device.

  Here, as the multifunctional electronic device, a smart phone, a tablet terminal or a PC (Personal Computer), an electronic blackboard, or the like is preferably used. When processing objects, a significant processing load is imposed on the CPU, but with smartphones and tablet devices, the processing performance has improved dramatically and the operating speed is comfortable even when executing object processing. Can be secured.

In addition, a portable multifunction electronic device has the advantage of portability, and therefore can easily learn a language when the user finds it convenient.
In addition, because of this portability, the language education system comprising a plurality of the language education terminals (Fig. 1), the educational material creator and students of the educational institution bring the terminal 1 together and connect them to each other by communication. 19) also has a secondary merit that it can be easily configured.

In this example, a multi-function electronic device is adopted, but it has become common knowledge that such a device includes a touch panel as an input means. Also, electronic devices having a gesture recognition function using an infrared sensor or the like are being put into practical use.
If these devices are used, the display object D and the group object G can be additionally arranged in the user data 122 by performing an operation by gesture input while directly observing the display screen, or existing by drag and drop. Objects D and G can be rearranged.
With this input function, the user can intuitively change the arrangement of pictures and characters that represent meaning, and it is possible to produce a great advantage that it is easy to perceive visually as seen in language learning by e-learning.

[Embodiment 2]
In language education, it is common to ask various questions to measure the level of understanding of learners. This question format includes a selection problem, a burial problem, and a rearrangement problem.
The program according to the second embodiment collates whether or not the identification character string assigned to the group object G matches the identification character string assigned to the subordinate object of the group object G under a predetermined determination condition. To do.

In order to realize the identification character string collation function, the language education terminal 1A in which the program is installed includes collation means 114 as shown in FIG.
As shown in FIG. 13, the collating unit 114 is subdivided by function into an identification character string setting unit 1141, a determination condition specifying unit 1142, and a character string collating unit 1143.

The identification character string setting unit 1141 gives an identification character string for uniquely identifying an arbitrary display object D or group object G to the object D or G according to the input contents of the user. When the display object D / group object G is composed of characters, character data may be used as an identification character string as it is by default.
Here, the identification character string assigned to the group object G corresponds to the correct answer in the question, and the identification character string assigned to the subordinate object corresponds to the answering limb.

The determination condition specifying unit 1142 compares the identification character string given to the group object G with the identification character string given to the subordinate object of the group object G according to the designation operation from the user. Specify judgment conditions.
In this example, (1) perfect match, (2) random order match, (3) partial match, etc. can be selected as the determination condition. When the user delimits each identification character string with “/ (slash)”, “& (ampersand)”, or other predetermined symbols, the character string collating means 1143 performs comparison under each order-matching / partial-matching condition.

When creating a rearrangement problem in which a given word is rearranged in the correct word order, the order of subordinate objects needs to match, and therefore, it is sufficient to specify perfect match as a determination condition.
In addition, when creating a selection question that selects all the given options from the given choices, the order in which the subordinate objects are arranged is unquestioned.
Furthermore, even when creating a selection question that selects a part of the choices according to the subject matter from the given choices, the order of arrangement of the subordinate objects is unquestioned, so partial matching may be specified as the determination condition.

After the identification character string and the determination condition are set, when the user adds, excludes, or rearranges (rearranges) the subordinate objects and further performs a character string matching operation, the character string matching unit 1143 displays the group object G And an identification character string assigned to each subordinate object of the group object G are acquired.
Then, the character string collating unit 1143 collates whether or not the acquired identification character string of the group object G matches the acquired identification character string of the subordinate object under the designated determination condition.

In the example of FIG. 14, the blank group object G-61 for answers is collated with the identification character strings of the display objects D-61 to D-66 of the group object G-62 for options. In the group object G-61, “Nihon is now what?” Is set as an identification character string, and a perfect match is designated as a determination condition by user selection.
In addition, “Nihon” is set as the identification character string in the display object D-65 which is image data, and character data as the identification character string is set in the display objects D-61 to D-64 and D-66. It is used as it is.
The answer group object G-61 is set to the individual processing mode and the automatic alignment function is set to ON.

  When an arbitrary object among the display objects D-61 to D-66 is dropped on the determination area of the group object G-61 by the user, the arbitrary object is added as a subordinate object of the group object G-61. Then, the automatic alignment means 11 automatically aligns all subordinate objects.

Further, when a character string collating operation is performed by the user, the character string collating unit 1143 designates collation between the identification character string of the group object G-61 and the identification character string of the subordinate object of the group object G-61. Perform based on judgment conditions.
In this example, since complete match is specified as the determination condition, if the subordinate objects of the group object G-61 are organized as shown in FIG. 15, it is determined that the identification character strings match under the determination condition. .
In this example, as shown in FIG. 15, the character string collating unit 1143 notifies the collation result (match or mismatch) according to the user's click operation. This notification form may be a screen display or may be read out by voice reproduction.

[Modification]
In the program according to the present invention, the learning material creator passes the electronic learning material (user data 122) created on the software installed on an arbitrary terminal to the learner, and the learner who has received the learning material learns the learning material. It is also possible to operate on this software installed on the terminal owned by the user.
However, if there is no restriction on data modification of the electronic teaching material, it is possible that the learner mistakenly changes or deletes the display object D or group object G in the electronic teaching material. When there is only one electronic teaching material data, there is a possibility that the data cannot be restored to the original state.
On the other hand, if any access to the display object by the learner is prohibited, interactive learning using the advantage of the electronic teaching material by operating the display object becomes impossible.
In order to solve such a problem, the program according to the present invention may be configured such that the use environment for learners and the use environment for teaching material creators can be set.

Here, “use environment for educational material creator” means display object D (see D-71 and D-72 in FIG. 16) and group object G (G-71 and G- in FIG. 16) as shown in FIG. 72) can be operated without limitation, and refers to a usage environment in which these destinations can be arbitrarily selected. Examples of material creators include educators and problem creators.
The “use environment for learners” refers to a use environment in which restrictions are imposed on objects that can be operated and places that can be moved to during a move operation.
In the initial state (default), the objects to be operated in the use environment for learners are limited to the subordinate objects of the group object G set to the individual processing mode, the objects set to the duplicate drag mode, and the like. The moving operation of the object to be operated is effective only when this object is added as a subordinate object of the group object G set to the individual processing mode.
For example, in the use environment for learners, as shown in FIG. 17, the objects that can be operated are limited to the subordinate objects of the object D-82 and the group object G-81 that are set to the duplication drag mode. The movement destination is also limited when it is added as a subordinate object of the group object G-81 set to the individual processing mode.

By using the above mechanism, the teaching material creator can arrange the object corresponding to the question option as a subordinate object of the group object G set in the individual processing mode, or set it in the duplicate drag mode. This allows the learner to operate the object.
In addition, by setting the part corresponding to the answer column of the question as a group object set to the individual processing mode, the answer can be added by adding (moving) the object for the option as a subordinate object of the group object for the answer column. Can be done.

Below, the usage example in the use environment for learners is shown by taking FIG. 14 as an example.
In the example of FIG. 14, since the group object G-62 is set to the individual processing mode, even under the use environment for learners, D-61 to D-66, which are subordinate objects of G-62, are operation targets. I can be. Therefore, the learner can drag and move any object D-61 to D-66. Further, since G-61, which is an empty group object having no subordinate object, is held in the individual processing mode, subordinate objects can be added to this group object G-61 even in a use environment for learners. It is. Therefore, in the use environment for learners, the learner drags and moves any of the objects D-61 to D-66 that are display objects for choice, and the subordinate object of G-61 that is the object for the answer column It is possible to answer questions by adding as.
Further, since the group object G-61 is held in the individual processing mode, it is possible to perform rearrangement by rearranging the subordinate objects added to the G-61 in the use environment for learners.
Further, since the group object G-62 is held in the individual processing mode, the object added as a subordinate object of the G-61 is excluded from the G-61 in the use environment for learners, and the G-62 is changed to the G-62. It is also possible to return (add as a subordinate object of G-62).

On the other hand, since the objects D-60, G-61, and G-62 are not subordinate objects of the group object held in the individual processing mode, these objects may be operation targets in the use environment for learners. Not possible (subordinate objects of G-61 and G-62 can be operated, but G-61 and G-62 themselves cannot be operated).
For this reason, the learner performs a moving operation on D-60, which is an object for instructing answers to questions, G-61, which is an object for answer fields, and G-62, which is an object for storing options. It is possible to prevent this operation.

Further, in the use environment for learners, the movement of the object is limited to the case where the object is added as a subordinate object of the group object held in the individual processing mode, and therefore D-61 to D-66 which are options objects. Can be confirmed only when added as a subordinate object of the group object G-61 and when rearranged within the group object G-62.
Accordingly, it is possible to prevent the option object from being moved to an unintended location of the learning material creator in the use environment for learners. In addition, since the object to be moved is guaranteed to be a subordinate object of the group object held in the individual processing mode when the movement is confirmed, it is guaranteed that the object becomes a movement object again after the movement is confirmed.
Thus, in the use environment for learners, it is possible to prevent the learner from performing an operation not intended by the creator of the teaching material while ensuring that the learner can perform an operation necessary for learning.

In order to realize the above function, the language education terminal 1B in which the program according to the modification is installed further includes user environment setting means 115 as shown in FIG.
The user environment setting means 115 is a means for switching between a learning material creator use environment and a learner use environment.

It is also possible to configure an application that operates only in a use environment for learners in which operable objects are limited.
In this case, since the function is reduced as compared with the environment for the educational material creator, this program can be provided at a low price, and it can be expected that the spread of e-learning in educational institutions will be promoted.

Furthermore, it is possible to prepare a plurality of terminals on which the above-described program is installed, and configure a language education system that can be used by a large number of people in educational institutions such as various schools.
As shown in FIG. 19, the language education system 100 of this example is a system in which a plurality of language education terminals 1 are connected in a communicable state via a public communication line 200 such as the Internet or a mobile communication network. .
When the public communication line 200 such as the Internet is employed, a high security level can be secured by using, for example, a VPN (Virtual Private Network) technology.

Since these terminals 1 share the same electronic learning material (user data 122) through the network, both the learning material creator and the learner can mutually confirm the modified content through the common electronic learning material. You can check the level of understanding and ask questions and advice smoothly.
Further, the user data 122 created by the teaching material creator can be distributed to the learners.

Furthermore, in this example, as shown in FIG. 19, an arbitrary language education terminal 1 is connected to the external monitor 300. The external monitor 300 is installed at a predetermined place where a language education lecture is performed for the purpose of sharing information between educators and learners through the screen.
According to the language education system 100, the display object D in the user data 122 can be edited and rearranged while the user data 122 created and edited in advance by the teaching material creator is presented to the learner on the screen.

  The present invention has been described above with reference to the embodiments, but the present invention is not limited to the above embodiments. Various modifications that can be understood by those skilled in the art can be made to the configuration and details of the present invention without departing from the gist of the present invention.
