DETAILED DESCRIPTION [Outline] In a character string input device having a function of inputting a character string displayed on a display device by a coordinate input device, the coordinate input A means for identifying that the position designated by the device is a specific region, and when the designation ends at a position corresponding to the specific region, it is not regarded as the end of the designation of the character string, and a new By providing a means for identifying the input target character string by regarding the character string input instruction started at 1) as a continuation instruction, the character string instruction can be easily performed.

[Industrial application field]

The present invention relates to an input device in a computer, and more particularly to a character string input device for inputting a character string to be searched into an electronic dictionary or the like.

With recent advances in computer technology, computer-aided learning (CA
L) has come into practical use, but in computer-aided learning (CAL), for example, when learning a language such as Japanese or English, it is necessary to look up a word whose meaning is unknown. come.

However, with the recent progress in semiconductor technology, as the capacity of memory elements has been increased and the economy has been increased, so-called electronic dictionaries have come into practical use. You can look it up.

At this time, in the past, the word of unknown meaning was input with a key, but there is a problem in terms of operability. Therefore, recently, the direct indication type input device has been put into practical use, and this direct indication type has been put into practice. An input method using an input device has come to be adopted.

In this method, the word whose meaning is unknown in the text displayed on the screen of the display device can be identified by touching the word with a special pen and the electronic dictionary can be searched.

Even in this case, if there is a line break in the middle of the word, there is a problem that the operability is poor, and regardless of whether there is a line break in the middle of the word or not, direct manipulative type in which unified maneuverability is obtained The character string input device has been required.

[Problems to be solved by conventional technology and invention]

FIG. 4 is a diagram illustrating a configuration example of a conventional character string input device, and FIG. 3 is a diagram illustrating an example of a sentence display screen.

First, the text to be learned is selected in the sentence presentation unit 1,
It is displayed on the display device 2. On the screen of the display device 2,
For example, a sentence as shown in FIG. 3 (a) is displayed.

The learner reads and learns this sentence, but if there is a word (word) whose meaning is incomprehensible in the sentence, he or she can instruct the word to look it up in an electronic dictionary (not shown).

Usually, a transparent coordinate input device 3 is overlaid on the surface of the screen of the display device 2, and when touched with a pen,
The coordinates are input.

For example, in FIG. 3, when it is desired to check “sulfur oxide”, touch “sulfur” with a pen as shown in FIG. 3 (b) and draw a line as it is to “yellow oxide”. Move the pen and at the "object" release it.

The position detecting unit 4 monitors the position of the pen, and the next character identifying unit 5 identifies the designated character according to the coordinate information. The identified characters are transmitted to the character string generation unit 6 one after another.
Sent to, where the strings are assembled.

After the pen is released, in the conventional method, an operation of notifying that the designation of the target character string is completed, for example, pressing a key or a menu displayed at a specific position on the screen of the display device 2 is performed. For example, operations such as selecting with the pen are performed from the completion notification input unit 7.

Therefore, both the operation required for character string instruction and the operation for notifying its completion are required. When the input target consists of n characters, generally, the total of n times of character instructions and one completion notification is required. The operation is required n + 1 times, and even if the input target is only one character, the operation is required twice.

When a word in the sentence displayed on the screen is designated and a search is performed in an electronic dictionary (not shown), the designated character string continues to exist, so each character constituting the word is designated. Instead of this, it is also possible to trace the character from the word start character to the word end character in succession at one time.

If the instruction method is limited in this way, basically the instruction of the target character string can be performed by one operation.
Since it is not necessary to give instructions in more than one time, there is no need to notify the completion of instruction input.

However, in reality, there may be a line break in the middle of a word, in which case the instruction will be terminated once and the instruction will continue from the beginning of the next line. Instructions cannot be given by one operation, and notification of instruction input completion is still required.

That is, the conventional method requires at least two operations in any case.

Considering the convenience of the user, the less the number of operations, the easier it is to use. Therefore, it is usually desirable to use the method of inputting the character string only once. Even when there is a line break in the middle of the word, if it can be processed by basically the same operation as in the case other than that, the input can be normally performed by one operation.

In view of the above-mentioned conventional drawbacks, the present invention provides a character string input instruction,
An object of the present invention is to provide a character string input device that can be easily operated with one operation regardless of the presence of line breaks.

[Means for solving problems]

FIG. 1 is a principle block diagram of a character string input device of the present invention.

In the present invention, in the character string input device having the function of inputting the character string of the sentence displayed on the display device 2 by the coordinate input device 3, the coordinate input device 3 is used. Means 8 for identifying that the designated position is a specific region, and when the designation ends at the position corresponding to the specific region, it is not considered that the designation of the character string ends, and a new It is configured to include means 9 and 6 for identifying the input target character string by regarding the started character string input instruction as a continuation instruction.

[Action]

That is, according to the present invention, in a character string input device having a function of inputting a character string of a sentence displayed on a display device by the coordinate input device, the coordinate input device is used. A means for identifying that the instructed position is a specific area, and when the instruction ends at a position corresponding to the specific area, it is not considered that the instruction of the character string has ended, and a new start is continued. By providing a means for identifying the input target character string by regarding the entered character string input instruction as a continuation instruction, the character string instruction can be easily performed. It is possible to give an instruction, and even in the case of a character string between which a line feed is inserted, the instruction can be given by an operation that is almost the same as a normal operation, so that there is an effect that a simple and convenient character string input means can be provided.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 2 is a block diagram showing an embodiment of the present invention.
FIG. 3 is a view showing an example of the text display screen, and the specific area identifying unit 8, the continuous processing requesting unit 9 and the related mechanism in FIG. 2 are means necessary for carrying out the present invention. The same reference numerals indicate the same objects throughout the drawings.

The function of the character string input device of the present invention will be described below with reference to FIGS. 2 and 3.

In the present embodiment, the present invention is applied to the input of a search character string when performing a dictionary search in a language learning device using a computer.

First, the text to be learned is selected in the sentence presentation unit 1,
It is displayed on the display device 2. On the screen of the display device 2,
For example, a sentence as shown in FIG. 3 (a) is displayed.

The learner reads and learns this sentence, but if there is a word (word) that does not make sense in the sentence, it can be looked up in the dictionary 11, for example, an electronic dictionary, by pointing the word.

Usually, a transparent coordinate input device 3 is overlaid on the surface of the screen of the display device 2, and when touched with a pen,
The coordinates are input.

For example, if you want to examine "sulfur sulfide" in Fig. 3 (a), touch "sulfur" with a pen as shown in Fig. 3 (b) and draw a line as it is to "yellow oxide". , Move the pen and at the "object" release it.

The position detecting unit 4 monitors the position of the pen, and the next character identifying unit 5 identifies the designated character according to the coordinate information. The identified characters are transmitted to the character string generation unit 6 one after another.
Sent to, where the strings are assembled.

When the pen is released, the position detection unit 4 sends the input end information to the character string identification unit 5, and when this information is transmitted to the character string generation unit 6, the character string " “Sulfur oxide” is sent to the dictionary search unit 10 as a search target word.

The dictionary search unit 10 searches the dictionary 11 for the heading "sulfur oxide", and when it finds it, the description is displayed in the search result presentation unit.
Send to 12.

The search result posting unit 12 sends the above-mentioned explanation to the display device 2 and displays it.

In this way, when there is no line feed in the middle of the search target character string, the character string can be designated by one operation.

Next, a method of designating a word between line breaks will be described.

For example, if you want to look up a "sprinkler",
Two strings, "su" and "prinkler," must be specified. If the pen is released after touching the "su" with the pen, only the "su" becomes the search target. Therefore, in the present invention, as shown in FIG.
After touching the "Su" with the pen, move the pen to the right.

On the right side of each line, as shown by "□" in Fig. 3 (d),
A continuation instruction area for one character is prepared, and when the pen enters this area, the specific area identification unit 8 determines that the continuation instruction has been issued and notifies the continuation processing request unit 9.

When the continuation process request unit 9 requests the character string generation unit 6 to perform the continuation process, the character string generation unit 6 retains the character string “s” generated up to that point.

Next, when "Prinkler" is instructed, the character string identification unit 5 causes the character string generation unit 6 to
Although "p" is sent, since the continuation processing is performed here, the generated character string is not "p" but "sp" after the already generated "s". Since the input end information is sent when the "sprinkler" is generated, the "sprinkler" is sent to the dictionary search unit 10 as a search target character string.

That is, when the instruction for the character string reaches the right end of the line, if the instruction target is up to that point, you can release the pen there,
If there is a continuation, the pen is extended to the right side, the pen is released, and a new character is designated from the beginning character of the next line, so that a character string connecting them can be input.

As described above, according to the present invention, by preparing a continuation instruction area for one character at the right end of a line and indicating the area with a pen, it is possible to indicate that there is a continuation in the character string that has been instructed so far. The characterizing feature is that the character string in the next line is connected to the character string in the previous line to be recognized as one word by recognition by the column input device.

〔The invention's effect〕

As described above in detail, the character string input system of the present invention has a function of inputting a character string of a sentence displayed on the display device by displaying the character string of the sentence on the coordinate input device. In the character string input device, means for identifying that the position designated by the coordinate input device is a specific area, and, if the designation ends at the position corresponding to the specific area, By providing a means for identifying a character string to be input by considering a newly started character string input instruction as a continuous instruction without regard to the end of the instruction, the character string instruction can be easily performed. Normally, a character string can be specified by one operation, and even in the case of a character string that inserts a line feed, it can be specified by an operation that is almost the same as a normal operation, so a simple and simple character string input means. Provided by There is a kill effect.
