Description

Korean input method using navigation button of wireless terminal {Method for korean alphabet insertion using navigation button in portable terminal}

The present invention relates to a Korean input method of a wireless terminal, and in particular, the user can recognize the characters at a glance and display the characters at a glance by displaying Korean consonants and vowels, English, and special characters on the LCD (Liquid Crystal Display) of the wireless terminal. The present invention relates to a Korean input method using a navigation button of a wireless terminal, which is suitable for simplifying Korean input and reducing an input error.

In general, a wireless terminal such as a mobile communication system includes an LCD display device. Therefore, the convenience of the user of the wireless terminal is increased through the user interface providing various menus.

On the other hand, the wireless terminal provides various functions in addition to the function for voice communication.

The present invention intends to improve a user interface applied when inputting a character, which will be described below.

The user of the terminal activates the text input mode by using a menu button in the standby state and inputs Korean or English indicated on each button of the keypad in sequence.

In this case, the text input mode has a menu or button for selecting a system of input text. When the user needs to input an English character among other character systems, for example, Korean input, the user switches to the English character input mode and inputs while looking at the characters displayed for each button of the keypad.

The entered character is then stored in memory for later retrieval.

In this way, the storage registration of the telephone number becomes possible.

However, the above-described prior art assigns the Hangul alphabet or English alphabet for each keypad and configures the corresponding character each time the keypad is pressed, and thus, a considerable inconvenience has been incurred when entering a character having a consonant structure of elementary / medium species like Hangul.

That is, when each letter is composed based on the Hangul complete system, the Hangul consonants are used simultaneously as the initial and final consonants. Therefore, it is not possible to determine whether the consonant following the vowel is the final or the first consonant. Thus, the consonant is treated as a finality, and if you want to enter a letter without a backing, move the cursor to the next space after the vowel so that the next consonant is the first consonant.

In addition, when a character is input through the keypad, the number of Korean consonants, vowels, or English alphabets assigned to each keypad is large, requiring several button operations to form a desired character. There was a high disadvantage.

Accordingly, the present invention has been proposed to solve the conventional problems as described above, an object of the present invention is to display the Korean consonants and vowels, English, special characters, etc. on the LCD (Liquid Crystal Display) of the wireless terminal user It is to provide a Hangul input method using the navigation button of the wireless terminal to make it easy to recognize the characters at a glance and to select using the move button, to simplify the Hangul input and reduce the input error.

The present invention improves the input interface of Korean, English, and special characters, including Korean when inputting a wireless terminal.

According to FIG. 2, the wireless terminal is a codec 11 for encoding / decoding a signal, a DSP 12 for digital signal processing, and a DSP 12 for signal processing for transmission of voice or text through a trunk line. Memory unit 13 for storing, and RF stage 14 for transmitting and receiving radio signals is configured.

In addition, in connection with a user interface for menu selection or character input / output, the wireless terminal may include a CPU 16 having an interface program, a font storage unit 16 storing a shape (font), and various characters input by a user. A non-volatile memory 17, an LCD unit 18 for displaying various characters and menus, and key input units 19 and 20 provided with buttons for user selection for menu selection and character input.

In addition to the keypad 19 having a plurality of buttons, the key input units 19 and 20 are further provided with navigation buttons 20 for moving the cursor. Using the navigation button 20, the cursor displayed on the LCD can be easily moved and selected between menu items or characters.

The wireless terminal configured as described above is in the standby mode in a normal operating environment (ST11).

When the user presses the 'menu button' provided in the keypad 19 in the standby mode, the menu is displayed on the LCD unit 18 (ST12).

When the menu is displayed, the user moves the cursor using the navigation button 20 and selects a menu item. In the following description, a menu item for registering a phone number is selected with reference to FIG. 3.

When the phone number registration menu is selected, the menu moves to the phone number registration window. The items entered when registering a phone number include a name and a phone number. Which item to enter first depends on the user's choice. Accordingly, the user selects any one of a name item and a phone number item currently displayed on the LCD unit 18 (ST13).

If the user moves to the name input box using the navigation button 20 and presses the OK button, the user enters the Hangul input mode (ST14 to ST15).

In the Hangul input mode, both the Hangul consonants and vowels are displayed on the LCD unit 18, and indicate one of the Hangul alphabets where the cursor is displayed. The displayed Hangul alphabet may consist of only the terminal sound and the short vowel, or may include some vowel consonants (ㄲ, ㅃ, etc.) or double vowels (ㅖ, ㅚ, etc.), and may be displayed in two or more rows depending on the shape and size of the LCD. . The shape (font) is read from the font storage unit 16.

The characters entered are displayed in the name input display window.

When you press the OK button, the consonant that the cursor currently points to is displayed on the name input display window. According to this procedure, the completed name is displayed on the name input display window by sequentially moving to the desired vowel or consonant and inputting the consonants forming the name.

At this time, the CPU 15 tries to form letters by the input letter. If one letter is configured according to a round-finished system, the cursor is automatically moved to the next space even if the user does not perform any other operation. Letters should consist of the following letters:

If you want to make a space between letters, move the cursor one space on the Hangul input display window using the move button. Use the move button to delete or move backwards while entering text. The movement button for moving the cursor of the Hangul input display window is implemented as an appropriate button (for example, buttons 1 and 3 of the keypad) in consideration of the left and right movement directions. The navigation button 20 is used to move and select the cursor among the displayed characters, and the navigation button is used to move the cursor on the display window in which the input letters are displayed.

When entering name in Hangul input mode, press registration button. Then, the Hangul input mode is terminated and the phone number registration window opens. If the phone number is not entered while the name is registered, the phone number must be entered and the registration button must be pressed. When both the name and the phone number are entered and the registration button is pressed, the CPU 15 stores the name and the phone number in the inactive memory 17 to complete the phone book (ST20).

The name and the phone number can be newly input / registered, and the registered name and the phone number can be edited using the edit button (ST21).

On the other hand, in addition to Hangul, English characters, special characters, or numbers may be input. For example, if you press the Korean / English switch button to change from the Hangul input mode to the English input mode or use the navigation button (20) to select the '>' to move to the next window in the Hangul alphabet display window, the uppercase letters of English appear on the LCD. All are displayed. In the English input mode or the special character input mode, the LCD screen is divided into a part where the alphabet is displayed and a part where the input character is displayed, as in the Korean input mode (ST16 to ST17).

4 shows an English character input window and a special character input window.

In the state in which the uppercase English letter is displayed, the user moves up, down, left, and right by using the navigation button 20 and selects an English letter to enter an English letter.

To input lowercase letters while entering uppercase letters, press the Korean / English button again or move to the next window and select '>'. Then, as in the operation of switching from the Korean input window to the English uppercase input window, an English lowercase input window is opened.

Inserting and deleting of blanks in each mode are done in the same way as in Korean input mode.

If you want to input special characters when entering Korean and English, press the Korean / English toggle button repeatedly until the special character window appears while the Korean consonant / vowel or English alphabet appears (ST18).

When the special character window appears, the character is checked and entered (ST19).

Switching between Korean mode, English uppercase mode, English lowercase mode, and special character mode is performed by continuous operation of Korean / English switching button or by continuous operation of '>' which is moving to next window.

When the input of the name and phone number is completed, the corresponding information is registered by pressing the registration button. At this time, the registered information is stored in the nonvolatile memory 17 so that it can be retrieved later.

When the phonebook registration is completed, the wireless terminal returns to the standby state.
