Description

Sliding 4-button compound input method and character input method {SLIDING 4-BUTTONS COMPLEX INPUT SYSTEM AND CHARACTER INPUT METHOD}

Embodiments of the present invention relate to a character input unit for inputting a character in a sliding type in a touch-based device.

Recently, devices such as smart phones and PDAs equipped with touch screens provide a text input method in which a finger is directly touched on a screen instead of a physical button type text input method. In particular, various touch technologies for detecting a single or a plurality of finger touches and a sliding of a finger are gradually commercialized. In addition, as various input interfaces are possible, various forms of character input methods have been proposed.

Korean Patent Laid-Open Publication No. 10-2006-0119527 (published November 24, 2006) is a slide method of disposing a character input area on a concentric circle around a fixed area where a user's finger is fixedly contacted on a touch screen. A character input technique capable of inputting a character is disclosed.

Qwerty input method, which is used in the existing mobile environment, places most characters on one screen, and therefore generally has 26 buttons. Each button is about 4mm wide and 6mm wide based on the 3.7-inch screen. It is composed. The QWERTY input button is significantly smaller than a normal adult user's finger, and has a large number of buttons. In addition, in the input device of the existing mobile device, since the position of the button for the special character is fixed, the user may need to find and input the position every time the special character is used, thereby reducing the input speed.

In the present specification, in order to solve the input typographic problem of the existing QWERTY input device, which is widely used in mobile devices, the number of buttons is increased, and the size of the buttons increases the size of the buttons easily and quickly with special functions that are frequently used by users. A character input device is proposed that can place the location of the user at a location convenient for the user.

In order to reduce the error rate of Korean and English inputs in mobile devices, such as relatively small screens, a four-button composite input device and texts that conveniently input Korean and English characters using four buttons are basically provided by reducing the number of buttons placed on the screen. Provide an input method.

In order to enable users to enter special characters easily and quickly, the present invention provides a four-button compound input method and a text input method including a function to support placing a user's frequently used special characters in a desired position.

Is it possible to customize the special character button? impossible possible Special character buttons can be arranged by the user arbitrarily to increase convenience and input speed.

Furthermore, in the present invention, it is possible to register a special character frequently used on the keyboard of the Hangul / English / numeric input mode. When a shortcut button is pressed and a special character is pressed on the keyboard of the special character input mode, a keyboard screen of the Hangul input mode appears as shown in FIG. 8. At this time, if one of the frequently used special characters ('!', '?', '@', '~') Is selected from the common keys displayed on the keyboard screen of the Korean input mode, the special characters are entered at the position. The special characters selected with the shortcut button in the mode are replaced with the special characters frequently used in the Hangul input mode. In this way, the characters frequently used by the user can be arbitrarily registered on the keyboard of the Hangul input mode.

In addition, it is possible to change the position of a special character frequently used in the keyboard of the special character input mode. Long pressing any one button in the keyboard state of the special character input mode shown in FIG. 7 activates the special characters to move (eg, buttons shake). With the movement of special characters activated, you can drag special characters that you use frequently and place them in the desired position. At this time, the special characters originally located at the corresponding position are placed one space to the right.

Hereinafter, a method of inputting a character through the push-type four-button composite input according to the present invention is as follows. The Hangul input mode among the various input modes will be described as an example.

As shown in FIG. 9, when a button for inputting Korean characters is pressed in total, characters are unfolded when a character input button is pressed. 'ㅋ', 'ㅎ', 'ㅡ' and 'ㅣ' used in the center of the four buttons are input by touching the buttons. At this time, 'ㅋ' and 'ㅎ' are used to display a lot of smiles of teenagers in their 20s and 20s so that they can be placed at the center of the button so that they can be input quickly with a single touch. Also, 'ㅡ' and 'ㅣ' are the basics of vowels, so they are placed in the center of the button, and other vowels are shifted according to the characteristics that other vowels can be made by adding cloth (·) to 'ㅡ' or 'ㅣ'. Place it in consideration of the direction in which it is located.

10 illustrates a consonant input form.

As shown in FIG. 10, while pressing and holding the 'ㅋ' or 'ㅎ' button, the letters input by pushing are expanded. Consonants with double consonants can be placed around the 'ㅋ' button to make them easier to learn. Push direction is 6 directions in total and push the button in the direction of the consonant to be input while releasing the hand to complete the input of the character.

11 illustrates a vowel input form.

As shown in FIG. 11, when the 'ㅡ' or 'ㅣ' button is pressed and held, the letters input by pushing are expanded. The 'ㅡ' button is configured to input the button with one cloth and ',', and the 'ㅣ' button is configured to enter the button with two cloths. Push direction is 4 or 5 directions in total. Push and hold the button in the direction of the vowel where you want to enter and release the character.

Fig. 12 shows the input form of twin consonants.

Double consonants can be entered using the 'ㅋ' button, and double consonants can be entered with up to two pushes. For example, if you want to input the double consonant 'ㄲ', as shown in Fig. 12, while pressing the 'ㅋ' button to push the terminal sound to select the terminal sound 'ㄱ' first and then in the direction of the 'ㅋ' button again Slide to select 'ㅋ' and 'ㅋ' is changed to 'ㄲ'. At this time, when the consonant 'ㄲ' is released and the hand is released, the twin consonant 'ㄲ' is input.

Fig. 13 shows the consonant input form.

For example, the double consonants may be input through a single touch and push operation using the 'ㅋ' button. As shown in FIG. 13, when the consonant is input, the consonant is selected when the first consonant is selected and then moved to the second consonant. For example, if you want to input 'ㄵ', push the 'b' and then 'ㅈ' with the 'ㅋ' button selected and release the consonant 'ㄵ'. At this time, when moving from 'b' to 'ㅈ' as shown, 'ㅈ' is converted to a double consonant 'ㄵ' combining two consonants. As an exception, 'ㄶ' can be added to the list of double consonants.

As another example, a double consonant can be input by two touches using the 'ㅋ' button and the 'ㅎ' button. That is, when inputting the double consonants, if you input the first consonant and then enter the second consonant, the consonant is changed to the double consonant. For example, if you want to input the double consonant 'ㄺ', push the 'ㄹ' direction while releasing the '' 'button and release' '' first. If you push to the left, 'ㄱ' is added to complete the double consonant 'ㄺ'. As described above, 'ㄺ', 'ㄼ', 'ㄽ' can be input only by using both the 'ㅋ' button and the 'ㅎ' button.

The double vowels are also the same as the above-described double consonant input method.

14 illustrates an input form of two vowels.

For example, after selecting a short vowel by pushing a predetermined direction in a state in which the '-' or 'ㅣ' button is selected, the stroke is added by pushing the hand to the position of the '-' or 'ㅣ' button again. For example, if you want to enter 'ㅐ', push 'ㅏ' with the 'ㅡ' button selected and push 'ㅡ' again to release '을'. In this case, if the user pushes the 'ㅡ' button from the 'ㅡ' button and then pushes the 'ㅡ' button again, the 'ㅡ' may be converted to 'ㅐ' and displayed.

As another example, you can enter a vowel with two in two touches. This is a method of adding a stroke, such as adding a stroke of Easy Hangul. For example, if you want to input '밀', push the 'ㅡ' button with the 'ㅡ' button selected, release it, enter 'ㅏ' first, then press the 'ㅣ' button to add a stroke. have.

The push-type four-button composite input device according to the present invention may support an input method using multi-touch. That is, when consonants and vowels are simultaneously input through multi-touch, the input characters are combined and input through an automata. Even if the vowel button is pressed first, pressing the consonant button before releasing the vowel results in multi-touch input. If you enter a vowel using multi-touch and then enter consonants, it is input as the finality. If you remove the consonant and press the consonant button again during multi-touch input, the first consonant is entered as a consonant and the second consonant is entered as a final.

Therefore, the push-type four-button composite input device according to the present invention basically reduces the number of buttons arranged on the screen to reduce the typing error of Korean and English inputs in a mobile device having a relatively small screen. To help you enter it. In addition, the push-type four-button composite input device according to the present invention can provide a function for supporting the user to place the special characters frequently used in a desired position in order to allow the user to enter the special characters easily and quickly. have.

Hereinafter, embodiments of the character input apparatus using the 4-button push equation will be described with reference to FIGS. 1 to 14. 15 is a block diagram showing the internal configuration of a push-type four-button composite input according to an embodiment of the present invention.

As shown in FIG. 15, the four-button composite input unit 1500 may include a touch sensing unit 1510, a mode setting unit 1520, a display control unit 1530, and a character input unit 1540. Can be. Each configuration of the four-button composite input unit illustrated in FIG. 15 may perform an independent function or operate in a form that is dependent on at least one configuration.

The four-button compound input 1500 provides character input functionality in devices with touch sensitive displays.

The touch sensitive display can further include proximity sensor arrays or other elements for determining at least one contact point with the touch sensitive display.

The touch detector 1510 detects whether a user touches and detects a touch position according to the user's touch and a pushing direction following the touch position. For example, when a user touches or touches a finger on a character input screen of a touch-sensitive display, the user moves the finger in a predetermined direction, and the touch sensing unit 1510 moves the touch position and the finger of the user. The moving direction (that is, the pushing direction) may be sensed to check the position value and the direction value corresponding thereto, and the checked position value and the direction value may be transmitted to the character input unit 1540.

The mode setting unit 1520 may set the text input mode by the input method selected by the user. In other words, the mode setting unit 1520 is a Korean input mode for inputting Hangul, an English input mode for inputting English, a special character input mode for inputting special characters or a number for inputting numbers according to a user's request. One of the input modes can be set as the character input mode.

The display control unit 1530 may arrange and display characters on the character input screen according to the character input mode. In the case of Korean or English, the display control unit 1530 divides the phoneme, which is the minimum unit of characters, into four character groups, and displays four character input buttons corresponding to the character group one-to-one on the character input screen. As shown in FIG. 1 and FIG. 4, the four character groups corresponding to Hangul are the first consonant group ㄱ, ㄴ, ㄷ ,,, ㅅ, ㅈ, ㅋ) and the second consonant group (ㄹ, ㅁ, ㅇ, ㅊ , ㅌ, ,, ㅎ), the first vowel group (ㅏ, ㅓ, ㅗ, ㅜ, ㅡ, ㅢ), and the second vowel group (ㅑ, ㅕ, ㅛ, ㅠ, ㅣ). Meanwhile, as shown in FIG. 5, the four letter groups corresponding to the English language include the first alphabet letter group (q, w, a, s, e, z, x) and the second alphabet letter group (r, d, f, g). , c, v), the third alphabet letter group (y, u, t, h, j, b, n), and the fourth alphabet letter group (i, k, l, o, m, p). In addition, the display control unit 1530 arranges one phoneme (hereinafter, referred to as 'center phoneme') among the phonemes belonging to the character group in the center of the letter input button and the other phoneme (hereinafter referred to as 'nearby phoneme') in the center. It can be arranged around the phoneme.
