The present invention relates to a Hangul computer keyboard device, and more particularly, to a syllable unit input method of a Hangul computer which can simultaneously input several letters forming a syllable.

The Hangul computer input device currently used uses the keyboard arranged according to Korean Industrial Standard KSC 5715 and inputs one letter at a time.

Using these keyboards, the maximum speed that can be entered by humans has reached its limit.

The human input process can be divided into two processes in terms of physiology.

The first is the process in which letters are perceived in the cerebral cortex through vision, and the second is the process in which the instructions in the cerebral cortex reach to the fingers after the recognition of the characters, and the fingers press their fingers to practice the instructions.

The limiting factor of input speed is not in the cognitive process but in the practice process, and the latter time is longer than the former.

In addition, no matter how much training the latter required time can be reduced to less than a certain time.

Therefore, the efficiency of input speed cannot be improved unless human input method is changed.

Since Koreans have been learning sentences based on syllables composed of many letters from a young age, syllables play an important role in the process of cognitive recognition.

As the musicians recognize the scores marked by chords, Koreans have a special ability to recognize Hangeul, which is composed of syllables composed of a combination of various letters.

For example, a person who knows sheet music can learn to play a piano in a series of chords more easily than a person who does not. If you can develop a special input keyboard that can touch syllables by pressing two to four keys (keys) simultaneously, It is said to be a good fit for Koreans who have a special knowledge in Korea.

Next, the existing Hangul computer has a disadvantage in that the syllable construction process is displayed in the monitor when a sentence is input. For example, two syllables called "value" result in a series of constructs, such as "gap, gap, gap, value". At first glance, the phrase "gap" or "gap" gives the impression that you have mistyped it.

There is no need to show the syllable construction process in the imager, but only the completed syllables give a concise impression. Beckard et al. (US Pat. No. 4,042,777, filed November 15, 1976, published August 16, 1977) devised an electronic, lightweight typewriter with only one hand.

10 letters are arranged in two rows so that 4 fingers can be inputted, and one finger is pressed or 2 or 4 adjacent letters are pressed at the same time to create 26 English letters.

The present invention is a device for inputting the Hangul having a much more complicated structure than English using a font and software in syllable units.

According to the present invention, (1) Korean characters are input in syllable units in consideration of the literacy of Korean-specific syllables, and (2) the syllables are simultaneously inputted with several Jamo alphabets, which can be faster and more efficient than conventional keyboards. 3) The purpose of the imager is to provide a device that shows only the completed syllables.

The present invention relates to a Hangul computer input keyboard device, and to allow simultaneous input of syllables with a unique arrangement of letters, the electronic signal generated when pressing several letters is controlled and accepted as software, and the conventional keyboard basic circuit Is usually used as is.

FIG. 1 shows the arrangement of the keyboards, which are arranged in three groups: the first group, the first group, the second group, and the third group.

Choseong-gun consists of 15 characters, placed on the right side of the keyboard, Neutral-group consists of 9, and placed below the center of the keyboard. Chongseong-gun, like Chosung, placed on the left side of the keyboard.

The constellation and chongseong groups are arranged in three rows of five rows, and the chongseong group is arranged in three columns of three rows.

The six fingers arranged in the two middle rows of the Chosung and Jongseong groups were entrusted by the second fingers of both hands, and the third, fourth and fifth fingers were enclosed by the third, fourth and fifth fingers in each column. do.

The six thumbs of the two right clefts of the clumped group are governed by the right thumb, and the three thumbs of the left cleft are governed by the left thumb.

Letters that do not receive a single item are combined by pressing two letters in each letter group at the same time.

As shown in FIG. 2, the five double consonants "ㄲ, ㄸ, ㅃ, ㅆ, ㅉ" of the Chosung group (1) indicate the case indicated by "ㅁ (pair)" and the pair of consonants in the upper right corner. 7 pairs ㄺ, ㄻ, ㄼ, ㄽ, ㅀ, ㅀ ", which consists of presses, and contains" "" of the Jongsung group (3). 5 pairs of support "ㄲ, ㄳ, ㄵ, ㄶ, ㄶ" which do not contain "d" are configured by pressing the item displayed in Configure.

Jamo composed in the Jong group is as shown in FIG.

"ㅘ, ㅙ, ㅚ, ㅛ" presses "O" and "Ah, Ae, Lee, Female" in order, and "ㅑ, ㅐ, ㅖ, ㅢ" is "Y (Y)" Press “ㅏ, ㅐ, ㅔ, ㅣ” in order to configure.

Now, for each syllable, the syllable is selected from each syllable group, and using the assigned finger, the syllable is composed.

An example thereof is shown as "fourth water".

You can also press the Jamo one by one until you are comfortable with this input method.

Once pressed, keep pressing until one syllable is completed.

A keyboard 1 is connected to a 5-input 23-output data divider encoder 2 and a multiplexer 3, which is a 4-input data selector, and the decoder 2 ) And the multiplexer (3) to the keyboard processor (4), the output (P ₁ , P ₂ ) of the keyboard processor (4) through the inverters (5, 6) input (D) of the flip-flop (7) And the data inputs (D ₁ ) of the serial to parallel conversion register (9), respectively, and the data outputs (Q _{A to} Q _H ) of the serial to parallel conversion register (9) are connected to the input data bus ( D ₀ -D ₇ ), and connect the output Q of the flip-flop 7 to the input D of the flip-flop 8, but not the output of the flip-flop 8.

Is the output of the serial-to-parallel conversion register (9)

To the interrupt request signal terminal, and reset the terminal of the keyboard processor (4).

Is the external keyboard reset signal terminal via the inverter (13)

And the external clock signal terminal PCLK to the clock terminal CLK of the flip-flops 7 and 8, the operation and effect of the apparatus of the present invention are the same as in FIG. The keycode signal is transmitted from the keyboard 1 when a predetermined letter of is pressed.

When a predetermined event is pressed, released and opened, the corresponding code is 128 plus the same code as shown in FIG.

That is, the seventh bit of the key code byte BYTE is set to "1". If there is no key code output, the output voltage is "0".

The start of the key code is indicated by the pressing of the keyboard 1, which is kept above 0.2 milliseconds (ms), after which the 8-bit code is sent at a rate of 0.1 milliseconds (ms) per bit.

Here, "1" represents high and "0" represents low.

The clock line of the keyboard 1 is delayed and inverted for two system clock cycles.

This clock line is used to convert the autonomous data bits in the serial-to-parallel conversion register 9.

This conversion is clocked by the keyboard clock signal generated by the keyboard processor 4.

When eight bits have been converted, the serial to parallel conversion register 9 is latched to provide an interrupt request signal.

The interrupt request signal may read a key code through the parallel input / output port 10 and may be utilized by a user to cancel the interrupt request signal.

The flowchart of the method of the present invention made under such a background includes a first step of checking whether a key scan code is a repetitive key scan code as shown in FIG. 6, or a group of keys in which the key scan code corresponds to a Hangul syllable. A second step of checking whether or not the value is a value indicating a, and if the key scanning code is a group of keyed display values in the second step, a group of keys corresponding to the Hangul syllables is set and pre-pressed A key scan code is used as the key scan code, and the corresponding key of the first key pressed to initialize the key scan code group for Hangul syllables is 80h added to the key scan code, and a key scan code representing the Hangul syllables. A third step of setting the set of as the key scan codes; and increasing and ending the index of the key scan code set which becomes part or all of the Hangul syllables following the third step. And a fifth step of checking for authorized release of the fourth stage, and a second value indicating the key scan code of the key group in step 2, or the key scan code is Hangul syllable key; If the key scan code is not the release key in the fifth step, the previously pressed key is used as the current key scan code, and the sixth step returns to the end of the third step; The seventh step of checking whether or not the key scanning code is the release key of the Hangul syllable, or if the key scanning code is the release key of the Hangul syllable, checking whether the index of the Hangul syllable is "Yi". If the scan code sets the index of the set to 0 and the key scan code does not display a group of keys corresponding to the Hangul syllables, the eighth step ends and if the index of the Hangul syllables among the eighth steps is not "I", Resets that the scan is not the key representing the Hangul syllable key, classifies the set of Hangul key scan codes, provides the same number for the corresponding Hangul syllables, and inputs the key scan codes Step 9 examines whether the Hangul syllable is found by determining the phoneme of the Hangul syllable, and if Hangul syllable is found in the ninth step, place the Hangul syllable number in the keyboard buffer and increase the number of Hangul syllables. In step 10, if the Korean syllable is not found in the ninth step, and ends with the innex of the key scan code set of the Hangul syllable, the index is set to 0. It was done.

That is, no matter how simultaneously pressing the items constituting the syllables, the scan code generated at this time cannot be generated at the same time.

This software program takes advantage of the fact that this code cannot be generated at the same time.

First, it sets the limit of the time when the electronic signal required to compose a syllable is given to the scan code of the case input to the microprocessor.

The make scan code of the first event determines the starting point, and the break scan code determines the completion point.

Second, the computer gives an instruction to select only the necessary signals from the signals of the remaining inputs within the set time. As the first scan's make scan code, since it knows the value of the break scan code, only the make scan code is selected by comparing this value with the make and break scan codes of the remaining events.

It is a unique program of Korean input that retrieves the syllable font from Hangul syllable memory by using the Pattern Search technique based on the collected make scan codes.

There are about 2,000 syllable fonts used in the Korean computer, but about 15 syllables require five letters.

In general characters, syllables made by pressing two or three letters account for 45% each, and syllables made by pressing four letters are about 10%, and syllables requiring five letters are about 0.1%.

As can be seen from this statistic, the input operation is a simple operation of pressing two to four items at the same time. Given the special knowledge of the syllables of Korean people, this input method not only shortens the time but also causes fatigue or boring even if it continues for a long time. Will not make you feel.

As described above, the present invention can dramatically improve the input efficiency of the Hangul computer by inputting the constituent elements simultaneously based on syllables that are the basis of Korean character recognition criteria.

Claims (2)

The alphabetical arrangement of the Korean keyboard is divided into three groups: Chosung (1), Neutral (2), and Jongsung (3). Chosung and Jongsung are located on both sides of the keyboard The syllable unit of the Hangul computer, which is placed at the bottom of the center, selects the letters that constitute one syllable from each letter group, and inputs one syllable by simultaneously pressing several selected letters (鍵, Key) (1 in Fig. 5). Input method. Using a software program to control and accept the electronic signals of the keyboard device (Fig. 6), the start point of the sound quality is made by the make scan code of the first entry into the microprocessor, and the break scan of the key is made. Break scan code is used to determine the completeness of the syllables, and compares the value of the electronic signal of the remaining incidents between them to select the make scan code from the remaining electronic signals. The syllable unit input method of the Hangul computer which finds the corresponding font in the Hangul syllable memory using the pattern search techique.
