DETAILED DESCRIPTION OF THE INVENTION [Outline] A character string information retrieval device, for example, a learning device, which has a display unit and an electronic dictionary controlled by a computer system, and how it is displayed on a display screen. For the purpose of providing a character string information retrieval device equipped with a character string input mechanism capable of recognizing character string information as a character string, an arbitrary character string on the display screen of the display unit can be continuously displayed with a pen, for example. Connect the ones that are specified and detected, or connect the ones that are discretely specified and detected with a pen in the order determined in advance regarding the display positional relationship on the screen, for example, in the order in which text sentences are arranged. By providing a means for forming a single character string, a plurality of continuous or discrete character strings are connected in sequence to form a single character string. The electronic dictionary is searched by the specified character string.

[Industrial applications]

The present invention relates to an input device in a computer system,
In particular, the present invention relates to a character string information retrieval device equipped with an electronic dictionary.

The electronic dictionary stores contents of various dictionaries such as a Japanese dictionary in a memory, and in order to look up the electronic dictionary, it is necessary to input a character string to be searched in some form.

When the character string to be searched is input, the memory is searched by the input character string, and information such as reading, meaning, and example of the character string stored in the memory corresponding to the character string is searched. Is read from the memory and displayed on the display device.

Such an electronic dictionary displays texts on a display device in sequence, and by incorporating the learning device into a learning device capable of advancing learning while interacting with a person trying to learn,
It is possible to improve learning efficiency.

However, with the recent spread of computer systems, Japanese language learning devices (CAL) controlled by the computer systems, for example, have come into practical use. , Because it will be handled by ordinary amateurs,
As a means for inputting a character string necessary for learning the Japanese language, it is necessary to have as good operability as possible.

[Problems to be solved by conventional technology and invention]

FIG. 5 is a diagram showing a configuration example of a conventional character string information retrieval device.

This example shows a conventional character string search method for a dictionary search in a learning device using a computer system.

First, the text 2 to be learned is displayed on the display unit 6 via the screen information storage unit 4 and the output unit 5, and the learner learns by reading the contents of the text displayed on the screen.

If there is an unknown word in the text of the text displayed on the screen, the learner can search the electronic dictionary 1 by inputting this word from the keyboard of the input unit 10. .

Hereinafter, a specific example thereof will be described. As described above,
If there is an unknown character in the text of the text displayed on the display unit 6, the learner presses a "start key" (not shown) and inputs the character from the input unit 10.

In this case, when inputting characters that do not exist on the keyboard, such as kanji, it is necessary to use kana-kanji conversion, roman kanji conversion, or the like, or to input and convert the character code of each kanji is there.

In this way, when the input of the corresponding character is completed, for example, by pressing the “end key”, the character is input to the search unit 3.

The search unit 3 searches the electronic dictionary 1 for the input and converted characters, reads information about the characters, and sends the read information to the image information storage unit 4, where the image is stored. It is stored in the form of information.

The screen information of the information on the characters stored in the screen information storage unit 4 is converted into a video signal in the output unit 5 and sent to the display unit 6, and is replaced with the content of the text or the content of the text. Is displayed.

In such a conventional method, if you do not know how to read the character string to be searched or the character code, you cannot enter it,
In addition, there is a problem that inputting is very troublesome.

In particular, when searching for a word in a sentence displayed on the display screen, even if the word is present in front of the eyes, it is necessary to re-input, and as described above, it takes time. Therefore, it was very difficult for learners to use.

In view of the above-mentioned conventional drawbacks, the present invention makes it possible to easily input a character string to be searched without prior knowledge when searching for a character string displayed on a display screen of a display display unit. The purpose is to provide a device.

[Means for solving problems]

FIG. 1 is a diagram showing a configuration example of a character string information retrieval device of the present invention.

The above problems can be solved by the character string information retrieval device configured as follows.

A character string information retrieving apparatus controlled by a computer system, comprising a display display unit 6, means for designating an arbitrary character on the display screen of the display display unit 6, and discretely on the display screen. Means 8 for detecting a designated character string and means 9 for connecting the detected plurality of discrete character strings in a predetermined order to form one character string.
And a storage device 1 that stores information about some character strings
And means 3 for retrieving information on the formed character string from the storage device 1.

[Action]

That is, according to the present invention, a display unit is provided,
In a character string information retrieval device controlled by a computer system, an arbitrary character string on the display screen of the display display unit is discretely designated by a pen and detected, for example, and the detected positional relationship is determined in advance. Ordered,
For example, by connecting in the order in which text sentences are arranged and forming a single character string, a continuous or discrete character string is sequentially connected to form a single character string, Since the electronic dictionary is searched by the formed character string, there is an effect that any displayed character string can be easily specified and set as a search target.

〔Example〕

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

FIG. 1 described above is a diagram showing a configuration example of the character string information retrieval device of the present invention, and FIG. 2 is a diagram showing a processing flow in the retrieval character string generation unit in the configuration example of the present invention. , Third
The figure is a diagram for explaining the character string generation method in the configuration example of the present invention, and the designated character string detection unit 8 and the detected character string combination unit 9 in FIG. 1 are means necessary for implementing the present invention. . Note that the same reference numerals indicate the same object throughout the drawings.

Hereinafter, a character string forming operation by the character string information retrieval device of the present invention will be described with reference to FIGS. 1 to 3.

Even if the present invention is carried out, the process of searching for a character string is not particularly different from that of the prior art, and therefore the description thereof will be omitted. Here, the character string to be searched from the text displayed on the screen of the display unit 6 The method of generating will be mainly described.

That is, according to the present invention, the character designating unit 7 including, for example, a transparent coordinate detecting device is mounted on the surface of the screen of the display display unit 6, and the learner uses a "start key" (not shown). After pressing "", a character on the display screen corresponding to the coordinates can be specified by touching an unknown character with the pen through the character specifying unit 7.

When a character on the screen is designated, the information is registered in the image information storage unit 4, and the designation of the designation is accepted by the display unit 6 through the output unit 5, for example, the brightness of the character is increased. It is displayed, for example.

Subsequently, when another character is designated, that character is also accepted.

When a character on the screen is designated (see FIG. 3), the information is registered in the screen information storage unit 4, and the designation is accepted by the display unit 6 through the output unit 5, for example, the third As in the case of the character "rough" in the figure, the brightness is modulated and displayed.

Subsequently, when another character (in this example, "re" excluding the character "(a)" following "rough", that is, a discrete "re" is specified (see FIG. 3), similarly, After that, when the characters are specified by repeating the same operation (see FIG. 3), the specified character string detection unit 8 is activated by pressing an “end key” (not shown). The information in the screen information storage unit 4 is checked to check whether or not it is a designated character in order from the first character on the screen, and the discrete designated character string is detected and connected (FIG. 2). Refer to each step indicated by "designated character string detection unit"8'in the flow chart of FIG. 4) If the designated character string is found and the next character is not the designated character, information on the character strings connected up to that point Is sent to the detected character string combining unit 9 and the character string is As the first character string, the designated character string detection unit 8 subsequently detects the designated character string (see the step of “Detected character string combination unit” 9 in the flowchart of FIG. 2). Parts 8'and 9 form a search character string by connecting discretely specified characters in the order in which they are detected (see FIG. 3).

When the characters on the screen have been checked to the end, the search unit 3 accesses the electronic dictionary 1 for the words of the search character string formed up to that point, and searches for the character string.

As described above, the present invention relates to a plurality of character strings in which arbitrarily dispersed character strings are designated by the character designating unit (pen) from the text displayed on the screen of the display display unit. It is characterized in that when the designated characters can be discretely recognized by scanning in the order in which the text sentences are arranged, one character string is generated by connecting them in the recognized order. An example in which a character string can be specified regardless of the order in which characters are specified is shown below.

(1) recovery A from the instruction mistake) the character of the character by character case calculations system (wrong first "Sun" of the system to single instruction instruction) in the calculation system (subsequently instructed the character of "total") calculation system (continue the character of the "death", "scan", "hand""no," the sequential instructions) → calculation system b) subsequent case of a system that character can instruct the string by tracing a straight line) calculation system ( "total" in Tatchimisu Missing) Calculation system (continue to indicate “total”) → Calculation system (2) Addition of character string a) In case of intending to change instruction during input Calculation system (initially intended to indicate “system”) Calculation system (and then, additional instructions reconsider the direction of the compound word "computing system" is appropriate as a search target word "calculating") → calculation system [effect of the invention] has been described in detail Further, the character string information retrieval device of the present invention includes a display display unit, and in the character string information retrieval device controlled by the computer system, an arbitrary character string on the display screen of the display display unit can be Detected by specifying discretely,
By providing a means for forming a single character string by connecting in the order defined by the display positional relationship, for example, in the order in which text sentences are arranged, a plurality of discrete character strings are connected in order to form a single character string. Is formed, and an electronic dictionary is searched with the formed character string.
There is an effect that any displayed character string can be easily specified and searched.
