Description

Apparatus and method of inputting Korean vowels}

The present invention relates to a Hangul input device and a method thereof, and more particularly to a Hangul input device and method that can easily input Hangul vowels.

There are a number of ways to input Hangul through various information communication terminals such as mobile phones, PDAs (Personal Digital Assistants) and personal computers.

Keyboards commonly used in computers have a QWERTY keyboard layout. A portable communication terminal such as a PDA has a touch screen as an input means, and a user touches a corresponding key on a software keyboard displayed on the touch screen using a stylus pen to input letters, numbers, or symbols. Enter it.

As a software keyboard applied to a portable communication terminal for Korean input, a software keyboard having a QWERTY keyboard layout is common. However, it is inconvenient for the user because the screen is small to display the entire keyboard on the screen. Therefore, in general, only some keyboards are displayed, and when the user presses a special key, the rest of the keyboards are adopted. However, there is still inconvenience in that the user has to input several keys.

Another software keyboard applied to a portable communication terminal for inputting a Korean character is a software keyboard having a keyboard layout in a natural manner.

FIG. 1 is a diagram illustrating an example of an anti-static keyboard layout. Cheonjiin (天地 人) method can input all Hangul vowels using three basic form elements, "·" (cheon), "ㅡ" (ji) and "ㅣ" (in), so you can enter a limited number of keys. It is useful for portable communication terminals such as PDAs that need to display keys on mobile phones or narrow touch screens.

However, even when the Korean vowels are input in the celestial manner, the user may have to make several key inputs.

Table 1 below shows an example of the number of key inputs when inputting Korean vowels according to the Cheonjiin method.

Hangul Vowel Key combination Input count ㅏ l + ㆍ 2 ㅑ l + ㆍ + ㆍ 3 ㅒ l + ㆍ + ㆍ + l 4 ㅖ ㆍ + ㆍ + l + l 4 ㅘ ㆍ + ㅡ + l + ㆍ 4 ㅙ ㆍ + ㅡ + l + ㆍ + l 5

As shown in Table 1, when the Korean vowel is input according to the Cheonjiin method, the user must enter the key five times as many times, and in the case of the double vowel, the user must enter the key four times.

In addition, in the case of the anti-corrosive keyboard shown in FIG. 1, "·" (thousand), "-" (ji) and "|" (phosphorus) are simply arranged side by side in a row at the top or bottom of the keyboard. Therefore, when a user wants to enter a vowel, the user first divides the vowel into three elements, "·" (thousand), "ㅡ" (ji), and "ㅣ" (in), and then enters it on the keyboard. You must go through the process of determining the order to be done.

Accordingly, an aspect of the present invention is to provide a Korean vowel input device and a method for easily inputting Korean vowels.

In order to achieve the above object, the Hangul input device according to an aspect of the present invention, the gesture database for storing the Hangul vowel code corresponding to each gesture input by the user through the touch screen; And a gesture confirmation unit which receives a gesture input by the user from the touch screen, searches the gesture database, and selects and outputs a Hangul vowel code corresponding to the gesture.

The display apparatus may further include a touch region confirming unit configured to confirm whether the region touched by the user is a collection region according to a touch region signal indicating an area touched by the user input from the touch screen. When one region is identified as a vowel region, the touch region signal is output to the gesture confirming unit, and the gesture confirming unit checks whether the input touch region signal is a gesture, and if the touch region signal is a gesture, the gesture database. Search and select a Hangul vowel code corresponding to the gesture is preferably output.

The gesture checking unit may determine the touch area signal as a gesture when the touch area signal is a signal generated in response to an operation of drawing a line in a predetermined vowel area displayed on the touch screen.

The vowel region may include a spiking region representing a vowel of a Hangul vowel at the center of the vowel region, a first horizontal region and a second horizontal stroke region representing a horizontal stroke of a Korean vowel at the top and bottom of the vowel region, respectively. It is preferable to include a first vertical stroke region and a second vertical stroke region respectively representing the vertical strokes of the Korean vowels on the left side and the right side.

The gesture checking unit may determine a gesture input by a user according to a type of a plurality of regions in which a line is drawn, from among a plurality of regions constituting the vowel region, and display the Hangul vowel code corresponding to the determined gesture in the gesture database. It is desirable to search and select.

In order to achieve the above object, the Hangul input method according to an aspect of the present invention,

(a) receiving a gesture from a user through a touch screen; determining a Hangul vowel corresponding to the gesture; And (c) outputting the determined Hangul vowels.

In addition, the step (a) may include (a1) determining whether the area touched by the user through the touch screen is a collection area; And (a2) if the area touched by the user is determined to be a collection area, determining whether the user touches the touch screen is a gesture.

In addition, the step (a2) is preferably a step of determining the user's operation as a gesture when the user's operation is a line drawing a predetermined vowel area displayed on the touch screen.

The vowel region may include a spiking region representing a vowel of a Hangul vowel at the center of the vowel region, a first horizontal region and a second horizontal stroke region representing a horizontal stroke of a Korean vowel at the top and bottom of the vowel region, respectively. It is preferable to include a first vertical stroke region and a second vertical stroke region respectively representing the vertical strokes of the Korean vowels on the left side and the right side.

In addition, the step (b) is a step of determining the gesture input by the user according to the type of the plurality of areas of the line among the plurality of areas constituting the vowel area.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a diagram illustrating an example of a keyboard for inputting Korean characters according to the present invention. Referring to FIG. 2, keys for consonant input are arranged on the left side of the keyboard, and a vowel area where keys for inputting a vowel are arranged on the right side of the keyboard.

3 is a diagram illustrating a specific example of a vowel region for Korean vowel input according to the present invention.

For the vowel input of the Hangul according to the present invention, three basic shape elements used in the conventional Cheonjiin method, namely, "|", "." And "-", are used.

Referring to FIG. 3, the vowel region according to the present invention includes a spiking region 2 representing "·" corresponding to a spiking of the Hangul vowel at its center, and a "" corresponding to the horizontal stroke of the Hangul vowel above and below the spiking region, respectively. The first horizontal stroke region 4 and the second horizontal stroke region 5 representing "-", and the first vertical stroke region 1 and second representing "l" corresponding to the vertical stroke of the Hangul vowel on the left and right sides of the squeezed region, respectively. The vertical stroke area 3 is included.

4A and 4B are views showing another modified example of the vowel region shown in FIG. 3. Similar to the vowel region shown in FIG. 3, horizontal stroke regions are formed above and below the spiking region, respectively, and vertical stroke regions are formed on the left and right sides of the spiking region, respectively.

5 is a diagram illustrating an example of inputting a Korean vowel through a vowel region according to the present invention illustrated in FIG. 3.

As illustrated in FIG. 3, a user inputs a vowel by touching an Hangul vowel area displayed on a predetermined area on a touch screen using an input means such as a stylus pen (not shown). Touching the collection area is divided into operations of clicking on an area on which a corresponding key is displayed with a stylus pen and drawing a line across a plurality of areas constituting the collection area as in the related art. The latter is called a gesture.

Gestures are introduced using the fact that the surface of the touch screen is smooth and the physical properties of the stylus pen used as an indicator make the stylus pen slide well on the touch screen.

Hereinafter, with reference to Figure 5 will be described the principle of inputting the Hangul vowel according to the present invention.

The large circle shown in the row corresponding to the gesture (or gesture + click) of FIG. 5 represents the squeezing area 2 of the vowel regions shown in FIG. 3. Although not specifically illustrated, similarly to the vowel region illustrated in FIG. 3, the first horizontal stroke region 4 and the second horizontal stroke region 5 exist above and below the squeezing region 2, respectively. On the left side and the right side of (2), the first vertical stroke region 1 and the second vertical stroke region 3 are present. In addition, a line segment represents a gesture by a user, and a dot represents a click.

Here are some examples of vowels to illustrate the principle of vowel input.

First, the case where the vowel "ㅏ" is input will be described. The user inputs the vowel " k " by performing a gesture of drawing a line across the first vertical stroke region 1 and the squeezing region 2 with a stylus pen. At this time, the direction of drawing a line does not matter. In other words, whether the line is drawn from the first vertical stroke region 1 to the pinching region 2 or the line from the pinching region 2 to the first vertical stroke region 1, the first vertical stroke region 1 and the pinching region If a line is drawn over the area 2, the Hangul input device according to the present invention determines that the input gesture represents the vowel "ㅏ". Therefore, in the conventional cheonji method to input the vowel "ㅏ", but the second key input, but according to the present invention is possible with one gesture operation.

Next, the case where the vowel "ㅑ" is input will be described. The user inputs the vowel “ㅑ” by clicking once with the stylus pen on the first vertical stroke region 1 and the squeezing region 2 by clicking the gesture and the squeezing region 2. At this time, the direction of drawing a line may be in any direction. The order in which the gesture and the click action are performed may be used. However, in a human writing habit, it is common to first perform a gesture for inputting "ㅑ" first, and then click on the pinch area 2 to input the pinch.

For input of the short vowel "-" or "l", the user only needs to click once on one of the two horizontal stroke areas 4 and 5 or one of the two vertical stroke areas 1 and 3, and no gesture action is required.

In the case of inputting the vowel “ㅐ”, the user performs a vowel “ㅐ” by performing a gesture of drawing a line from the first vertical stroke region 1 to the second vertical stroke region 3 through the squeezing region 2 with the stylus pen. ".

In summary, among the plurality of regions constituting the vowel region, the corresponding Hangul vowel is uniquely determined according to which region the user draws a line. Accordingly, as shown in FIG. 5, a gesture (or a combination of a gesture and a click) uniquely corresponding to each Hangul vowel may be determined.

As such, the user may easily input a desired Korean vowel by using a gesture and a gesture of clicking the vowel area displayed on the touch screen using a stylus pen.

Hereinafter, a Hangul input device according to an embodiment of the present invention will be described.

6 is a block diagram of a Hangul input device according to an embodiment of the present invention.

Referring to FIG. 6, the Hangul input device according to the present invention includes a touch screen 11, a touch area checking unit 12, a gesture checking unit 13, a gesture database 14, a preceding collection processing unit 15, and a preceding collection. Storage 16 and character set database 17;

The touch screen 11 displays the Hangul vowel area according to the present invention as described above, and transmits a signal indicating the area touched by the user, for example, a coordinate signal indicating the position of the touched area to the touch area checking unit 12. Output A single coordinate signal is output in the click operation, but a continuous coordinate signal is output in the gesture of drawing a line in the vowel area.

The touch area checking unit 12 receives a coordinate signal indicating the position of the area touched by the user from the touch screen 11 and checks whether the touched area is a vowel area. If a consonant key or a number or other character key other than the vowel area is touched, the touch area confirmation unit 12 controls the character set database 17 to output the corresponding consonant or other character to the touch screen 11. The touch area checking unit 12 controls the preceding vowel processing unit 15 to delete the preceding vowels stored in the preceding vowel storage unit 16, if any.

When it is determined that the touched area is the vowel area, the touch area checker 12 outputs a coordinate signal indicating the position of the area touched by the user from the touch screen 11 to the gesture checker 13.

The gesture confirmation unit 13 receives a signal indicating the position of the area touched by the user from the touch area confirmation unit 12 and checks whether the input signal is a signal indicating the gesture. If the input signal is not a single coordinate signal but a continuous coordinate signal, the gesture check unit 13 determines that the input signal is a signal indicating a gesture.

If it is determined that the input signal is a gesture, the gesture check unit 13 searches the gesture database 14, reads the Hangul vowel code corresponding to the input gesture, and outputs it to the preceding vowel processing unit 15.

For example, if a continuous coordinate signal is input from a coordinate belonging to the first vertical stroke region 1 to a coordinate belonging to the pinching region 2, the gesture checking unit 13 may refer to the gesture database 14 to collect the input gesture. After confirming that "ㅏ" is indicated, the Korean vowel code indicating vowel "ㅏ" is read, and then output to the preceding vowel processing unit 15.

The gesture database 14 stores pairs of values of a coordinate corresponding to a gesture or a combination of a gesture and a click and a Hangul vowel code corresponding to each.

If the signal input to the gesture checking unit 13 is not a gesture but a signal corresponding to a click operation, the Hangul vowel code corresponding to the click operation is output to the preceding vowel processing unit 15.

The preceding vowel processing unit 15 is a device for processing a double vowel. The preceding vowel storage unit 16 stores the preceding vowel input immediately before the current input character for the vowel processing.

The preceding vowel processing unit 15 checks whether there is a preceding vowel code stored in the preceding vowel storage unit 16 when receiving the Hangul vowel code from the gesture confirming unit 13. If there is a preceding vowel code stored in the preceding vowel storage unit 16, the vowel code and the inputted vowel code are synthesized by referring to the gesture database 14, and a predetermined double vowel code is output to the character set database 17. For example, in the case of "ㅖ" in the vowel shown in FIG. 5, when the first user draws a line from the squeezing area 2 to the second vertical stroke area 3, the vowel "ㅓ" in the preceding vowel storage unit 16. The corresponding code is stored. When the user draws a line from the squeezing area 2 to the second vertical stroke area 3 again, the preceding vowel processing unit 15 receives a code corresponding to "제" from the gesture confirming unit 13 and the preceding vowel storage unit. With reference to the code and gesture database 14 corresponding to "ㅓ" stored in (16), a code corresponding to the double vowel "ㅖ" is output to the character set database 17.

Hereinafter, a Hangul vowel input method according to an embodiment of the present invention will be described.

7 is a flowchart illustrating a Hangul vowel input method according to an embodiment of the present invention.

In operation 20, a user inputs a signal by touching a touch screen on which a predetermined Hangul vowel area is displayed. The touch screen outputs a coordinate signal indicative of the location touched by the user. A single coordinate signal is output in the click operation, but a continuous coordinate signal is output in the gesture of drawing a line in the vowel area.

It is determined whether the area touched by the user is the collection area (step 21).

If a key in an area other than the vowel area is touched, the corresponding consonant or other character is determined (step 22), and if the stored preceding vowel exists, it is deleted (step 28) and displayed on the screen through the touch screen. (30 step).

However, if the area touched by the user is a vowel area, it is determined whether the signal input by the user is a signal representing a gesture (step 23). If the input signal is not a single coordinate signal but a continuous coordinate signal, it is determined that the input signal is a signal representing a gesture.

If the input signal is a gesture, a Hangul vowel corresponding to the input gesture is determined (step 25). For example, if the input signal is a continuous coordinate signal from the coordinates belonging to the first vertical stroke region 1 to the coordinates belonging to the pinching region 2, it may be determined that the input gesture represents the vowel “ㅏ”.

However, if the input signal is not a gesture but a signal corresponding to a click operation, a Hangul vowel code corresponding to the clicked region is determined (step 24).

After determining the Hangul vowels indicated by the user's input in step 24 or 25, it is determined whether there is a preceding vowel input for the vowel processing (step 26).

If there is a preceding vowel, a predetermined vowel vowel is synthesized according to the preceding vowel and the input vowel (step 27).

After the twenty-seventh step, the preceding vowel stored in the predetermined memory is deleted (step 28). Since it is already used for compounding the vowels, the preceding vowel stored in the predetermined memory is deleted and left blank for the next vowel processing.

However, if there is no stored preceding vowel, the input vowel is stored in a predetermined memory (step 29). If there is a next vowel input by the user for double vowel input, the vowel is stored in the predetermined memory for double vowel processing. However, if the next input is a consonant or other, not a vowel symbol or number, the preceding vowel stored by step 28 is deleted.

Finally, the vowel other characters input by the user through the touch screen are displayed through a predetermined screen on the touch screen (step 30).
