DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a first embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram illustrating components of a blind user input device according to the present invention. FIG. 2 is a perspective view showing a time setting unit, an audio output unit, and a one- FIG. 3 is a circuit diagram showing a configuration of key input means for a visually impaired person among the constituent elements of a visually impaired person's handwriting input device according to the present invention, which includes a key input means for a visually impaired person, Means for modifying characters, key input means for character modification, control means for inputting, modifying, synthesizing and transmitting characters.

Here, the character input display means, the text modification display means, the character modification key input means, the character input, correction, synthesizing, and transmission control means are the same as those of the caption broadcasting system disclosed in Patent Registration No. 10-0325501 filed by the present applicant The detailed description of the shorthand character input system will be omitted.

The key input unit for a visually impaired person according to the present invention comprises a voice transmission device 110 and a shorthand input device 120.

First, the voice transmission apparatus 110 will be described.

The voice transmission apparatus 110 according to the present invention includes a time setting unit 111, a voice output unit 113, and a one-chip microcomputer unit 112 electrically connected to one side and the other side of the headset.

3, the time setting unit 111 divides the time by a sound to one side of the headset for the visually impaired, and it is a jumper switch 111-1 having a plurality of jumper 111a And a resistor 111b connected in parallel with a plurality of resistors R1, R2, R3, and R4 having different resistance values, and is configured to manually change a resistance value according to a user's selection, And a speaker 114 is connected to one side of the speaker so that sound is output.

Here, instead of the jumper switch 111a and the resistor portion 111b, a user may arbitrarily configure a variable resistor capable of adjusting a resistance value.

For the visually impaired, the sound that flows into the headset is set to come out at 3-second intervals via the narration voice and the mechanical sound because one cycle per shorthand input is 6 seconds, shouting time is 3 seconds, This is because the time is 3 seconds. Thus, a blind person shamed the shorthanded input for three seconds, and the public can correct for three seconds as a correction worker.

For example, the narrator voice may be recorded by specifying the narrator as "1 second", "2 seconds", or "3 seconds", or mixed with instrumental music so that the shorthanded input is not disturbed.

As another example, the mechanical sound may be composed of a mechanical sound such as "beep (1 second) to beep (2 seconds) to beep gain (3 seconds)", or a natural sound such as a cuckoo or a cricket .

Next, the sound output unit 113 is a place where the sound of the broadcast screen is output in real time according to the time set by the time setting unit on the other side of the headset. As shown in FIG. 3, And is connected to a resistor R6 connected to one side of the terminal, so that the visually impaired person can output the sound of the broadcast screen required for the shorthand input for 3 seconds through the control of the one-chip microcomputer.

The one-chip microcomputer 112 sets the time of the time setting unit, filters the sound of the broadcasting screen that is broadcasted in real time to the sound output unit, removes noise, and controls the sound to be outputted at a predetermined time, A speaker 114 of the time setting unit is connected to one end of the output terminal and a sound output unit 114 is connected to one side of the other output terminal via a resistor R6, Respectively.

Next, the shorthanded input device 120 according to the present invention inputs a word or a sentence which is abbreviated as one key when a blind spoken input is input as a caption character of a voice transmitted through the voice transmission device 110, And a shorthand input device having a function of deleting erroneously inputted characters at a time.

The shorthand device 120 according to the present invention may further include a shorthand key 121 and a backspace key 122 in a shorthand keyboard having a prefix, a neutral, and a vertex.

The abbreviation key 121 is used to allow a user to set a separate abbreviation for one unit character on the shorthand keyboard and store it in the abbreviation database DB so that when the unit character is inputted as one key, .

Here, the unit character refers to a Korean consonant or a vowel combined with any one or more of the initial, neutral, and consonant keys on the shorthand keyboard.

Abbreviation input through this abbreviation key can be input as shown in Table 1 below.

First letter (first letter) Second letter (neutral) End character (Jongseong) Word example Example of Abbreviated Input Initial So He Initial First consonant of second letter The first collection of ending letters patent office Þ + þ + ㅓ First consonant Attorney G Initial First collection of second letter The first collection of ending letters Patent Office Þ + þ + ㅗ First consonant of second letter . N Initial First consonant of second letter First consonant I love you. + + + +

As shown in Table 1, the abbreviation can input the abbreviation of the abbreviation at the convenience of the user through the Korean consonant or vowel, which is selectively combined with one or more of the performance neutrality and the abbreviation key through the shorthand keyboard.

In Table 1, for example, consonants, vowels, numbers, special characters, etc., which can be reminded at the convenience of the user, can be mixed and input, and the input speed can be improved through the weak key.

In addition, the abbreviation database refers to a database in which abbreviations are inputted by consonants and vowels in the order of first, second, and last, in the order of the user, and the categories are included in each category.

The fact that these databases are organized by categories,

In addition to the censorship (nouns, investigations, pronouns)

A number usage database indicating the quantity or order of objects,

A supplementary database for modifying verbs and adjectives,

A database of phrases attached after nouns, pronouns, and rhetoric to indicate or add meaning to the grammatical relationship between the words and other words,

The admiration use database which simply shows the surprise, feeling,

It is divided into a database for describing the action at the back of the sentence or a descriptive database describing the state or the state of things.

A database configured by the above categories is expressed as shown in Table 3 below.

Types of databases An example Name-use database Love, Patent Office, Patent Attorney, Patent Office .... Database of dummy names This, that, that, here, there, there, that, she .... Tubular Usage Database New, Untitled, Old .... Number database One, two, three, first, second, third .... An attached database Very, very well, very much, very much .... Working database The,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, In the words ... Admirable use database Yeah, okay, y'know, yes (when you answer) .... Dictionaries database Is it, I do, I do, I do, I am, I am, I say ....

As shown in FIG. 6, the backspace key 122 according to the present invention is formed on one side of the shorthand, neutral, and affixed keys on the shorthand keyboard to erase the entire character immediately before the erroneous input during shorthand, As shown in FIG. 7, when a backspace is input after inputting a character in the character input mode through the control of the controller in the shorthand keyboard, a backspace key mode for erasing the entire previous character positioned before the typed cursor 23 is operated .

By configuring the backspace key on the shorthand keyboard, the visually impaired can correct the error character immediately, so that more accurate caption characters can be input.

Hereinafter, a specific operation of the blind user input device according to the present invention will be described.

First, it is assumed that, as an initial condition for the operation description, the time for modification and the time for shorthand are set in the control means for the character input, correction, synthesis, and transmission as in the case of the general shorthand input. That is, it is assumed that one cycle is 6 seconds, the shouting time is 3 seconds, and the correction or break time is 3 seconds. The number of shorthand character inputters (PERSONS) is 2, Worker.

As shown in FIG. 4, the screen of the monitor at the time when the visually impaired shorthand letters input by the blind is input is displayed on the display means 20 for transmission of characters A shorthand character display section (21) is configured to display a shorthand character entered by a blind character input by a blind person at the lower end of the transmission sentence display section (33) And a modified character display unit 31 for displaying modified characters inputted by the general correction operator at the lower end of the modified character display unit 21. On the left side of the shorthand character display section 21, a self-correction character display area 21a for displaying characters modified by a general correction operator is formed. On the right side of the self-correction character display area 21a, And a next modified character display area 21b for displaying a character input by the shorthand character inputting unit. Here, reference numeral 22 denotes a cursor.

In one embodiment, as shown in Fig. 7, the driving process of the visually impaired shorthanded input device includes:

A broadcast screen is output from the television, and the shorthand input time is output to the headset at intervals of 3 seconds (S300 to S310), under the control of the one-chip microcomputer section, from the time setting section to the sound (mechanical sound or natural sound).

At the same time, according to the shorthand input time (3 seconds) set by the time setting unit, the voice of the television broadcast screen is output to the other side of the headset through the voice output unit at step S320.

The driving of the audio output unit according to the time setting unit is as shown in FIG.

In other words, a time setting sound notifying of 3 seconds flows through one side of the headset, and at the same time, the sound of the broadcasting screen is flowing through the other side of the headset "East Sea and Mt.

At this time, the subtitle character corresponding to the audio of the television broadcast screen heard in the audio output unit is input to the shorthand keyboard until the blind character input by the blind character disappears for 3 seconds of time setting sound (S330).

If the unit character designated by the abbreviation is input during the subtitle character input by the visually impaired shorthand character inputting person, the abbreviated mode is activated and the abbreviated word or sentences are inputted at once (S340 to S341).

In addition, if there is a caption character in which a blind character input by a visually impaired person is erroneously inputted during the caption character input, the blind character input by the blind character drives the backspace key to delete the entire preceding character at once (S350 to S351).

Then, characters are output to the control means for inputting, correcting, synthesizing, and transmitting the characters from the blind key input means (S342).

Next, as shown in Fig. 4, characters are output from the character input, correction, synthesis and transmission control means 50 to the image distributor (S342).

And then outputted from the image distributor to the shorthand character display section 21 and the modified character display section 31 of the character input display means 20. [

Next, characters are displayed on the character input display means and character display means.

Then, the general correction worker moves the report cursor from the left to the right on the character displayed on the modified character display section, finds a part to be corrected, and corrects the corrected character.

Hereinafter, control means for inputting, modifying, synthesizing and transmitting characters, means for transmitting a sentence, means for transmitting to an external communication station, and an operation procedure are described in Patent Citation No. 10-0325501 filed by the present applicant And a detailed description will be omitted.

Through the above-described constitution and operation process, the present invention can be applied to a visually impaired user's input device and method so that a blind keyboard same as that of a general person can be used by a conventional blind person so that a subtitle is displayed on a broadcast screen and a screen Shorthand input becomes possible.

As described above, according to the visually impaired person's shorthand input device and method according to the present invention, since a plurality of visually impaired shorthand letters input by a blind character and a general correction worker can alternately input shorthand characters, The accuracy of how words are similar to words when you hear them) can hold more than 98%, which is a good effect for blind people to break down the barriers of employment in companies in the computer.
