Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a help function for assisting a user's operation in a computer application, an OA device, a home electric appliance, and the like. The present invention relates to an apparatus and a computer-readable recording medium on which a program for realizing the function is recorded.

[0002]

2. Description of the Related Art Computer software such as word processors or home electric appliances such as VCRs include:
A function for assisting the user called an assist function or a help function for displaying a description of the operation by performing a specific operation such as pressing a help key when the operation method is unclear is provided. By using this help function and referring to information for assisting the user, it is possible to easily check the explanation of the necessary function when necessary even if the user does not remember all the operation methods.

However, in a system in which the number of functions is enormous due to the increase in the number of functions, it is difficult for a user to find a necessary function description simply by displaying all the function descriptions. For this reason, it is necessary to appropriately grasp the function requested by the user and display a corresponding operation description. Japanese Patent Laid-Open No. 7-121563 discloses that the user presses a help key and then inputs a keyword. Do
Japanese Patent Application Laid-Open No. Sho 61-243517 discloses a "help information search device" for searching for and displaying appropriate help information by keyword matching, and discloses two or more function keys after a user presses a help key. "Information processing apparatus with help function" that sequentially presses and displays the most appropriate help according to the combination.

[0004]

The above "help information search device" performs a search by keyword matching. For example, if the keyword (centering, centering) is given to the centering function of the Japanese word processor, and a request sentence "centering" or "centering" is given by the user, centering is performed by matching the keywords. Function is searched. However, in the search by keyword matching, "center" is used to search for the centering function.
Does not match the keyword (centering, center alignment) assigned to the centering function, the centering function cannot be searched.
It is virtually impossible to pre-register all keywords that are assumed to be input by the user, and even beginners may not even know that there is a centering function, and cannot input a request sentence There is a problem that sometimes. As described above, the search method based on keyword matching has a limitation as a help display device.

[0005] The above-mentioned "information processing apparatus with help function" displays the most appropriate help display by a combination of function keys input after the help key is pressed. The help display of the function that requires pressing the function key is performed by the combination of. Therefore, the help display of the related function is not performed although the function key is not pressed. In addition, only one function is displayed by the combination, and related functions cannot be displayed in a related order. For example, "cursor" is used for manuals
Although there are many functions that require key operation, related functions cannot be displayed except for functions that are directly related to the “cursor” key, such as “display next page”. Also, no matter how many times the same function key is pressed, it is treated as if it were pressed once. For example, when the left cursor movement key is pressed once, a help display related to the movement is displayed, and when the cursor movement key is pressed many times, the help display of the “line start” key cannot be displayed. Furthermore, in both of the above methods, when displaying the help, it is necessary to press the help key and then input a request statement or a function key, and it is essential that the user actively input after pressing the help key. is there.

[0006] The present invention has been made in view of such problems of the prior art, and when the help key is pressed,
An object of the present invention is to provide a help display device that retrieves and displays appropriate help information from a user's key operation history up to that time, and a computer-readable recording medium that records a program for realizing the function.

[0007]

According to the present invention, a key input operation history of a user at the time when a help key is pressed is converted into a feature vector, and appropriate help information is searched using the feature vector. The above purpose is achieved by displaying. That is, the help display device according to the present invention includes:
A key input operation history storage unit for storing a history of key input operations, a key vector dictionary for holding key vectors representing key characteristics, and a description of each function to be displayed as a help and a feature of the description A key input operation for generating a key input operation vector representing characteristics of a key input operation from a key input operation history stored in a key operation history storage unit with reference to a function description database holding an explanatory sentence vector and a key vector dictionary It is characterized by comprising a vector generation means and a search means for searching for a corresponding function from a function description database based on the key input operation vector generated by the key input operation vector generation means.

The help display device searches the function description database based on the history of the user's key input operation, so that the user does not need to input a keyword or a request sentence for the search, and the user can input the search result. Even if you do not have knowledge about the function, you can search and display the description about the function,
Appropriate help display can be performed when the help key is pressed. Further, by converting a key input into a feature vector (key input operation vector) and performing a search using the feature vector, a function description sentence close to the key input feature vector is searched for. It is not necessary to store all possible key input operations, and even if the user's key input operation is slightly different from the expected one, the functions searched for in order from the closest function are displayed in order and displayed. Can be displayed.

The help display device further includes a reading function storage means for storing a function read when the help display is performed, and based on the contents of the key input operation history storage means and the reading function storage means and the key vector dictionary. May be provided with a key input operation learning means for learning an explanatory note vector. In this case, the explanation text vector in the function explanation database is learned based on the record of the explanation text of which function was read by the user when the help display was performed. By displaying the help vector, the key vector dictionary is learned.
The more the help display device is used, the more the search accuracy of the help display can be improved.

[0010] The key input operation learning means can also learn key vectors based on the contents of the key input operation history storage means and the read function storage means and the key vector dictionary. In this case, the learning of the key vector dictionary is performed on the basis of the key input operation history and the record of which function the user has read when explaining the help. Since the key vector dictionary is learned by performing the help display, the accuracy of the search for the help display can be improved as the help display device is used.

According to the present invention, there is provided a machine-readable recording medium comprising: a computer for storing key input operation history storing means for storing a history of key input operations; a key vector dictionary for storing key vectors representing key characteristics; Function description database means for holding a description of each function to be displayed and a description vector representing characteristics of the description;
A key input operation vector generating means for generating a key input operation vector representing a characteristic of the key input operation from the key input operation history stored in the key operation history storage means with reference to the key vector dictionary; and a key input operation vector generating means. A program is recorded for functioning as search means for searching for a corresponding function from a function description database based on the generated key input operation vector.

Further, in the present invention, the key input operation history of the user at the time when the help key is pressed is converted into a keyword, and appropriate help information is searched and displayed using the keyword, thereby displaying the help information. To achieve. In other words, the help display device according to the present invention has a key input operation history storage unit for storing a history of key input operations, and a function of storing a description of an operation procedure of each function key and a function description corresponding to each function name. It is characterized by comprising an explanation database and a search means for searching a function explanation database for a corresponding function name for a history of key input operations.

More specifically, there is provided a keyword conversion means for converting a key operation into a keyword, and the retrieval means comprises a keyword converted from the key input operation history stored in the key input operation history storage means by the keyword conversion means. The search may be performed based on the degree of matching of the keyword with the function description sentence of the function description database. According to this help display device, when the help key is pressed when the operation of the device is not understood, the key operation history of the user is converted into a keyword, and appropriate help information is searched and displayed. It is not necessary to input a request sentence or a keyword for performing the operation, and the work efficiency can be improved.

[0014] The apparatus further includes a keyword conversion means for converting a key operation into a keyword, and the function description database includes a function description sentence for explaining a key operation procedure of each function and an associative key operation list associated with each function. The search means may perform a search based on the degree of coincidence between the keyword converted by the keyword conversion means and the associative key operation list from the history of the key input operation stored in the key input operation unattendance storage means. it can. In this case, even if the user does not perform the key operation according to the key operation procedure of the description of each function, if the user matches the associative key operation list, the function can be searched and displayed. it can. In addition, for each function, a beginner who does not know the function registers the key operation for performing the same as an associative key operation list, and when the help key is pressed, a more convenient function is searched and displayed. Therefore, the user interface is greatly improved over the conventional help function.

A machine-readable recording medium according to the present invention is a computer-readable recording medium storing key input operation history storing means for storing a history of key input operations, and a description of an operation procedure of each function key or a function description for each function name. A program is recorded for functioning as a function description database to be held in association with the search function, and a search unit for searching for a function corresponding to the history of key input operation from the function description database. The “feature vector” (specifically, “key vector”, “description vector”, and “key input operation vector”) referred to in this specification is the IEICE Technical Report AI92-99 issued by the Institute of Electronics, Information and Communication Engineers. (1993) It corresponds to a context vector proposed in "associative search from a large-scale database". JP-A-6-195388 discloses an example in which this feature vector is used for retrieval.

The "feature vector" indicates the degree of the relationship between the concept and the context of the word in the sentence, and is a vector representation of the degree of the semantic connection between many feature words. is there. If N concept classifications are feature words,
The value of each element of the N-dimensional vector corresponds to each characteristic word. The feature vector X _i = (x
_i1 , x _i2 ,..., x _iN ) are 0 ≦ x _ij ≦ E _m
Becomes _Em is a positive constant. Word i and feature word j
If there is no relationship between the two, x _ij = 0, and if there is a relationship, a large value is taken according to the degree of the relationship.
For example, the feature vector has five feature words (natural, urban,
Noise, animal, and green), and when the value of each element is a binary value of 0 or 1, the feature vector of the word “mountain” is set to (1, 0, 0, 1, 1) And so on.

[0017]

Embodiments of the present invention will be described below with reference to the drawings. Here, a help display device of a Japanese word processor (hereinafter abbreviated as word processor) will be described as an example. FIG. 1 shows a schematic configuration of an example of a help display device according to the present invention. The help display device includes an input unit 1 such as a keyboard for performing a key input operation, an output unit 2 such as a display for displaying a searched function and a description thereof, and a control unit for controlling the help display device. 3,
The system includes a function description database 7 for storing a description of a function and a description vector representing the characteristics of the description, and a key vector dictionary 8 for storing a key vector representing the characteristics of the key.
The control means 3 includes a key input operation history storage means 4 for storing a history of key input operations, a key input operation vector generating means 5 for generating a key input operation vector representing characteristics of the key input operations, a key input operation Search means 6 for searching the function description database 7 from the vector is included.
The input means 1 is provided for the target device of the help display device such as a word processing device or a personal computer running word processing software, and the output device 2 is usually provided for the target device of the help display device. It is.

FIG. 2 shows a help display device 9 and a target device 10.
FIG. The help display device 9 shown in FIG. 2 is obtained by separating the input means 1 and the output means 2 from the help display device shown in FIG. The target device 10 is
This is the target for help display, here the personal computer running word processing software. When the target device 10 is used, data input by a key from the input unit 1 is transmitted to the target device 10 and also to the help display device 9, and the history of the key input operation is stored in the help display device 9. It is stored in the key input operation history storage means 4. Then, the user cannot understand the operation of the target device 10,
When a key for calling a help display device such as a "help key" is pressed, the help display device 9 searches the function description database 7 based on the key input operation history stored in the key input operation history storage means 4, The description of the function as the search result is output to the output unit 2.

A method for searching the function description database 7 based on the history of key input operations will be described below. Key input operation data input from the input unit 1 is coded and stored in the key input operation history storage unit 4. FIG. 3 shows an example of data stored in the key input operation history storage means 4. In FIG. 3, the history of the input key is coded and stored in a two-digit decimal number, and the input data is added one after another. In the actual key input operation history storage means 4, the number of histories that can be stored is limited,
The old history may be deleted every time a new history is added.

The function description database 7 holds a description of each function of the target device of the help display device, in this case, a description of each function of the word processor, and a description text vector representing the characteristics of the description. FIG. 4 shows an example of data stored in the function description database 7. FIG. 4 shows an example of a function name, a description, and a description vector for the five functions of the word processor, "centering", "indent", "double size display", "cursor movement", and "line head movement". Here, it is assumed that the description sentence vector is nine-dimensional and the characteristic word is (move, up, down, left, right, delete, insert, shape, enlarge). The description sentence vector is normalized so that its size becomes 10. Here, the magnitude of a vector refers to the value of the square root of the sum of squares of each element of the vector.

The key vector dictionary 8 holds key vectors representing key characteristics. FIG. 5 shows an example of a part of the key vectors held in the key vector dictionary 8. In this example, for example, the key code “00” and the key vector (1, 0, 0, 1, 1, 1,
0, 0, 1, 0) is assigned, and the “line start (CTR
The (L + A) ”key is assigned a key code“ 07 ”and a key vector (1, 0, 0, 1, 0, 0, 0, 0, 0). In order to explain the correspondence between the key code and the actual key, a column of “corresponding key” is added in FIG. 5, but only the pair of the key code and the key vector is included in the actual key vector dictionary 8. Has been saved. In this example, each element of the key vector has a binary value of 0 and 1. The “general character key” in the “corresponding key” column is a kana or alphabet key that is not directly related to the word processing function.

FIG. 6 is a flowchart showing the flow of a function explanation display process using the help display device. When the "help key" or the like is pressed (S11) and the help display is performed, first, the history of the key input operation is retrieved from the key input operation history storage unit 4 (S12), and the history is stored in the key input operation vector generation unit. 5 will be sent. here,
The history of the five most recently entered key input operations is taken out from the key input operation history storage means 4, and the input of the "help key" is not included in the history. There are other ways to retrieve the key input operation history, such as the method of extracting from the most recent one to the place where the "execute" key is pressed last for the execution of the function, or the key input "insert (input)" ,
There is a method of classifying into several modes such as "delete" and "move", and taking out from the newest one to the place where the mode was last switched.

If the data stored in the key input operation history storage means 4 is as shown in FIG. 3, "08, 11, 0
5, 05, 05 "are extracted,
It is sent to the key input operation vector generation means 5. The key input operation vector generation means 5 refers to the key vector dictionary 8 and generates a key input operation vector representing the characteristics of the transmitted key input operation (S13). The key input operation vector is calculated by normalizing the sum of the key vectors corresponding to each key. If the key vector for each key code is as shown in FIG.
The sum Vs of the vectors corresponding to the two key codes is as follows.

Vs = (4,0,0,3,1,0,2,0,0) A vector Vn obtained by normalizing the vector Vs so that the magnitude becomes 10 is as follows. Vn = (7.3,0,0,5.5,1.8,0,3.
(7, 0, 0) The key input operation vector generated in this way is sent to the search means 6 to search for a function corresponding to this key input operation (S14). The search means 6 has a function having an explanatory note vector that is close to the key input operation vector Vn generated by the key input operation vector generation means 5.
Search from the function explanation database 7. In order to calculate the distance between the two feature vectors, the inner product value of the two vectors is calculated here. Both vectors have a size of 1
Since it is normalized to 0, its inner product value is from 0 to 100
And the closer to 100, the closer the distance between the two vectors is. Key input operation vector Vn
Calculating the inner product value P (x) of the function and the explanatory note vector of each function x shown in FIG.

P (centering) = 64.97 P (indent) = 61.32 P (double size display) = 24.2 P (cursor movement) = 81.03 P (line head movement) = 90.84 The function whose distance from the input operation vector Vn is short is “line start”. Then, the function names of the functions searched in order from the shortest distance to the key input operation vector Vn are output to the output means 2 as candidates as follows (S1).
5). However, the point does not have to be displayed.

1. (90 points) Move to beginning of line 2. (81 points) Cursor movement (64 points) Centering 4. (61 points) Indent 5. (24 points) Double-width display

When the user selects a description of a function through the input means 1 (S16), the description of the selected function is read from the function description database 7 and output to the output means 2 (S17). In this manner, related functions can be ranked and displayed based on the history of key input operations.
In addition, when the same key is pressed several times, the effect of the key vector becomes stronger.
The effect of the key becomes stronger, and "line start" is searched at the top. In the case of the history “08, 11, 06, 06, 05” in which the “left cursor” key is pressed only once, the sum Vs of the vectors corresponding to the above five key codes and the size Vs The vector Vn normalized so that is equal to 10 is as follows.

Vs = (4,0,0,1,3,0,2,0,0) Vn = (7.3,0,0,1.8,5.5,0,3.
(7, 0, 0) Therefore, when the inner product value P (x) of the key input operation vector Vn and the explanatory text vector of each function x shown in FIG. 4 is calculated, the result is as follows. Will be searched at the top.

P (centering) = 64.97 P (indent) = 76.86 P (double-width display) = 24.2 P (cursor movement) = 81.03 P (head of line) = 70.49

FIG. 7 shows a schematic configuration of a help display device in which a part related to key input operation learning is extracted. The part for learning the key input operation includes the control means 3 for controlling the help display device, the function explanation database 7, and the key vector dictionary 8. The control means 3 includes a key input operation history storage means 4, a read function storage means 11 for storing functions read by the user at the time of help display, and a key input operation learning means 12 for learning a key vector dictionary.

Next, a method of learning an explanatory sentence vector by learning key input operations will be described. In the reading function storage means 11, a search is performed on the help display device,
When the list of searched functions is displayed, the function that the user has requested to display the description of the function is stored. FIG. 8 shows an example of data recorded in the reading function storage unit 11. The “index” in FIG. 8 is for indicating the position of the key input history in the key input operation history storage means 4 referred to when the help display is performed, and the “selected function” is used by the user. This is the function that performed the reading. There may be a plurality of read functions.

The key input operation learning means 12 reads the key input operation history of the corresponding portion from the key input operation history storage means 4 by using the data recorded in the read function storage means 11 as a correct answer set for learning. And FIG.
Create a learning table like Here, the history of the key input operation five times earlier than the point indicated by “index” in FIG. 8 is extracted. Then, referring to the key vector dictionary 8, a function vector representing the feature of each function is created. The function vector V _f (x) of the function x is calculated as follows.

V _f (x) = f (V _k (x, i)) where V _k (x, i) corresponds to a key code included in the function x of the learning table created as shown in FIG. Is a key vector of the key vector dictionary 8 where f is some function related to V _k (x, i). As an example of the function f, there is a method of normalizing by taking the sum of the key vectors V _k (x, i). That is, the function vector V _k (x) of the function x is calculated as follows.

V _f (x) = k × ΣV _k (x, i) where k is a coefficient for normalizing the magnitude of the vector. For example, the function vector V _f (double-size display) of the function “double-size display” in FIG. 9 is as follows. Where V _k (n)
Represents a key vector of the key vector dictionary 8 corresponding to the key code n.

V _f (double size display) = k × ｛V _k (02) + V _k (5
4) + V _k (21) + V _k (10) + V _k (12)｝ The function vector V _f (x) created in this way is replaced with the description vector of the function description database 7. As described above, by using the explanatory note vector created by learning based on the user's key input operation history,
As the user displays the help, the user can search for a function that matches the user's input.

Next, the key input operation learning of the help display device for learning the key vector will be described. Using the function vector V _f (x) learned as described above, the learned key vector V _k2 (n) corresponding to the key code n is
It is calculated as follows:

V _k2 (n) = g (V _f (n, i)) Here, V _f (n, i) includes the key code n in the function of the learning table created as shown in FIG. Where g is some function related to V _f (n, i). As an example of the function g, there is a method as follows.

V _k2 (n) = k × ΣV _f (n, i) where k is a coefficient for normalizing the magnitude of the vector. For example, in the case of the learning table of FIG. 9, the key vector V _k2 (54) after learning the key code 54 is calculated as follows and stored in the key vector dictionary 8.

V _k2 (54) = k × ｛V _f (centering) +
2 x _Vf (indent) + _Vf (double-width display) + _Vf (page break) 学習 Learning is performed according to the user's selection of the function description, so the more the user displays help, the more user input You will be able to search for the function that matches. When the key vector dictionary is to be learned first, the key vector dictionary can be created manually. In the previous example, the feature words of the key vector are
(Up, down, left, right, delete, insert, format, enlarge) according to the meaning of "space", "tab", "delete", etc. printed on each key on the actual keyboard. Key vectors can be created. The key vector to be created may be created for all keys, or may be created only for frequently used keys. In this way, by defining a feature word for each element of the key vector, the key vector can be given a meaning, and by comparing the value of each element assigned to the vector with the feature word, , Key vectors can be easily maintained.

Next, another embodiment of the help display device according to the present invention will be described. FIG. 10 is a schematic configuration diagram showing another example of the help display device according to the present invention. The help display device includes an input unit 1 for inputting a document by a key input operation, an output unit 2 such as a display, a control unit 3, and a function explanation database 17. The control means 3 includes a key input operation history storage means 4 and a keyword conversion means 1 described later by hardware or software.
5 and the function of the search means 16.

FIG. 11 shows a part of an example of the function explanation database 17. The function description database 17 holds word processor function names such as "centering" and "indent", as well as a description of the function, a key operation procedure for realizing the function, and an associative key operation list.

FIG. 12 is a flowchart for explaining the processing procedure of the help display device of the present invention. When the user who cannot understand the operation of the word processor presses the help key (S21), the control unit 3 retrieves the key operation history of the user from the key operation history storage unit 4 (S22). For example, the history of five recently input key input operations is extracted from the key operation history storage means 4, and a "help key"
Will not be included in the history. The keyword conversion means 15 converts a key operation directly corresponding to the function in the key operation history into a keyword (S23).

The keyword conversion means 15 can be realized by a key code / keyword correspondence table as shown in FIG. For example, when the "centering" key is pressed, the key code "00" is converted into the keyword "centering". The same applies to a case where "centering" is selected from a menu with a mouse or the like instead of the "centering" key. By not including the general character key in the key code / keyword correspondence table, only the key code corresponding to the word processing function in the key operation history is converted into the keyword.

The search means 16 is a function explanation database 17
Is searched for a function that matches the key operation history (S24),
The searched function name is displayed on the output means 2 (S25).
The function displayed here may be one or plural. If a plurality of functions are displayed, the user selects a desired function from the displayed functions (S26). When a function is selected, the search unit 16 displays a function description of the selected function on the output unit 2 (S27).

Next, an example in which the search means 16 performs a search by a keyword search method will be described more specifically. Here, the "centering" function in word processing editing will be described as an example. As described in the function description database shown in FIG. 11, the "centering" function is a function of moving a designated character string to the center of a line, and the key operation procedure is to center the "cursor". Move to the character string and press the "Centering" key.

It is assumed that the word processing user tries to center the document title, does not know the operation method, presses the "centering" key, and then presses the help key (S2).
1). The key code "00" corresponding to the "centering" key is taken as the key operation history (S22). The key code "00" is converted into the keyword "centering" by the keyword conversion means 15 (S23), and the function description database 4 is converted by the keyword "centering".
Is searched (S24).

In the search, in this example, a keyword is extracted from the text of the key operation procedure for the function explanation database and used for the search. This keyword extraction can be easily realized by preparing a keyword table corresponding to the key operation in advance. In this case, (centering, cursor) is extracted from the function item of “centering” in the function description database as a keyword. Similarly, from the function item "Indent" (cursor,
Indent) is extracted.

As shown in FIG. 14, a keyword and a function list from which the keyword is extracted are created in advance as an index table. The search is performed by ranking each function item by the number including the keyword converted from the key operation history based on the index table of FIG. 14, and then displaying the function name on the output means 2 (S25). In this case, the function name “centering” is searched because the keyword (centering) converted from the key operation history matches, and the function name “indent” is not searched because the keyword does not match. If the user has also pressed the "cursor" key, "indent" is also searched for as the next candidate. If multiple feature names are searched at the same time,
After allowing the user to select an appropriate one from among them and narrowing down to one function (S26), a description is displayed (S2).
7).

Next, an example using the associative key operation list shown in FIG. 11 will be described. In the associative key operation list, a key operation list in which a novice who does not know the existence of the function is assumed to obtain the same effect as when using the function is registered in advance. For example, in the “centering” function, “delete”, “space”, and “tab” keys are registered on the assumption that a user who does not know the centering function performs a key operation for performing “centering”.

It is assumed that the word processor user presses the "space" key several times, presses the "delete" key, and then presses the help key in order to center the title of the document (S21). "Space" as key operation history
The key and the "delete" key are taken (S22) and converted into the keywords "space" and "delete" (S23),
The function description database 17 is searched by the keywords "space" and "delete" (S24). “Centering” and “indent” where the associative key operation list matches the keyword are output as candidates. In addition, "space (blank input)" and "delete (delete one character)" are also output as lower candidates (S25). After allowing the user to select an appropriate one from among them and narrowing it down to one item (S2
6), a description is displayed (S27). In this way, even when there is no operation procedure that matches the key operation history in the function description, an appropriate function can be searched for by using the associative key operation list.

In order to function as the help display device of the present invention, a program for executing the above-described processing is recorded in a computer-readable recording medium such as a floppy disk or a CD-ROM in advance, and is stored in the computer. It may be installed and used.
