Description

 Touch keypad and mobile communication terminal {TOUCH KEYPAD AND MOBILE COMMUNICATION TERMINAL}

The present invention relates to a character input method in a touch screen terminal, and more particularly, to a touch keypad and a character input method capable of effectively inputting characters such as English uppercase letters or Hangul twins.

Mobile communication terminals, which have established themselves as essential personal care products, are becoming more and more advanced, such as voice communication and video communication, as well as high-speed, high-capacity data transmission and reception. Various types of models such as a smart phone that adds computer support functions such as Internet communication and information retrieval to a mobile phone and a tablet that combines a cell phone and a laptop function have been released.

Unlike a personal computer (PC), such a mobile communication terminal is smaller in size than a PC because it is intended for mobility, and as a result, how to configure the arrangement or structure of the keyboard for character input is of interest. . In a typical keypad, 10 numbers are arranged in a line, and using the QWERTY keyboard, which displays two small function keys in English or a short vowel in Korean and a terminal sound in addition to two function keys, or by changing the arrangement of characters to the mobile communication terminal. In some cases, a suitable keypad may be configured.

1 is a view showing an example of a conventional touch keypad used in a mobile communication terminal. In particular, FIGS. 1 (a) and 1 (b) are the English keyboard and the Korean keyboard of the mobile short vowel keyboard provided by Google, respectively.

Due to the small screen size, the touch keypad of such a mobile communication terminal is forced to decrease the size of the input key, and the English lowercase and uppercase letters, or Hangul single (short and short vowels) and twin (double and double vowels). Since it is not possible to display all on a single screen, a method of displaying a double tone is used by using a function key such as a shift key or by repeatedly inputting a single key. In particular, in the case of using a function key (shift key), it is difficult to use two fingers at the same time because it is necessary to press the desired letter key while pressing the function key to input uppercase letters or double tones. There is a problem in that it is inconvenient to use the keypad of a mobile communication terminal that is frequently used. On the other hand, if you use it with one hand, you can press the desired letter key after pressing the function key (for example, the up arrow key) for switching between uppercase letters / twins, since these function keys are applied to all keys on the keypad at the same time. There is a hassle of frequently using function keys when inputting alternately between lower and lower case letters, single and double tones.

Due to this, an error occurs frequently in the process of a user inputting text through the touch screen of the mobile communication terminal, and a problem occurs in that the text input time is increased.

As a method for solving such a problem, it can be considered as a method of improving the input operation of the touch keypad through software, a method of updating the character arrangement of the touch keypad, and a method of changing the hardware structure of the mobile communication terminal. For example, Patent Publication No. 10-2002-0077547 (English uppercase letter input method) is an example of an access method through software, which is to discriminate at the time of pressing the keyboard to input uppercase letters, and to register Patent Publication No. 10 -1034284 (character input device) is an example of an access method through character arrangement of a touch keypad, and is a method of constructing a screen keyboard in which priority is sequentially assigned from 1st rank to subsequent rank. In addition, Korean Patent Application Publication No. 10-2011-0085522 (a split keyboard that allows easy input of binary consonants) is an example of an approach to change the hardware structure of a mobile communication terminal. It is a way to operate as a key with shift function applied.

However, the method of inputting uppercase letters by discriminating at the time of pressing the keyboard, such as published patent publication No. 10-2002-0077547, has a high probability of inputting a typo as an input method depending on the user's senses, and is intuitively input by the user There is a difficulty in recognizing characters. In addition, as in Patent Registration No. 10-1034284, a method of changing the keyboard layout of the touch keypad has a problem in that it takes additional effort and time for the user to get used to it by changing the existing keypad arrangement. In addition, as disclosed in Korean Patent Publication No. 10-2011-0085522, a method of changing hardware of a mobile communication terminal has a problem that additional cost and time are required according to manufacturing of the terminal.

Publication Patent Publication No. 10-2002-0077547 (2002.10.12) Registered Patent Publication No. 10-1034284 (2011.05.16) Patent Publication No. 10-2011-0085522 (2011.07.27)

2 is an exemplary view of a screen of a touch keypad to which an individual switch function is applied according to an embodiment of the present invention.

Referring to FIG. 2, the touch keypad to which the individual switch function of the present invention is applied uses the existing touch keypad as it is, but specifies the characters to be switched, such as English uppercase letters or Hangul double consonants and double vowels, For each character input key, a switch function that can be converted individually for each character to be switched, such as upper and lower case letters, terminal and double consonants, or single and double vowels, is added. Here, the case of the Korean keyboard is shown as an example.

Therefore, the touch keypad to which the individual switch function of the present invention is applied can be applied to any existing arrangements of keyboards, such as QWERTY keyboards, Samsung's Cheonjiin keyboards, and LG's Naratgle keyboards, and the same applies to newly used new keyboards thereafter. It is possible to do.

The switch target characters shown as examples in FIG. 2 are terminal vowels a, c, ㅂ, ㅅ, ㅈ constituting 단자, ㄸ, ㅃ, ㅆ, ㅉ as double consonants in the Korean keyboard, and ㅑ, ㅕ, ㅈ as double vowels, Short vowels constituting ㅠ, ㅒ, ㅖ may include ㅏ, 구성, ㅗ, ㅜ, ㅐ, ㅔ. Here, because the character to be switched is specified by using Google's mobile short vowel keyboard as an example, it is classified as 5 consonants and 6 vowels. Therefore, the character to be switched may be changed according to the type of keyboard used.

It is preferable that the touch keypad to which the individual switch function of the present invention is applied allows the user to intuitively recognize this by displaying the character to be switched to the user. Therefore, it is preferable to display an indication indicating the switch function for each input key corresponding to the character to be switched. For example, a red solid line shape (such as a solid line bar shape of the heater switch) can be added to the character portion to be switched. will be. Through the display of the character to be switched, the user can visually recognize that it is possible to convert to uppercase letters, double consonants, or double vowels.

Referring to FIG. 3, the touch keypad to which the individual switch function according to an embodiment of the present invention is applied may be applied to various languages by reflecting the language notation method of each country such as Chinese or Japanese as well as English and Korean. In addition, since a notation method or a keyboard layout may be changed within a single language, a character to be switched may be changed accordingly.

As described above, when applied to an English keyboard, all lowercase letters can be specified as a switch target character to convert to uppercase letters. In this case, a switch function capable of converting to uppercase letters for each input key of each lowercase letter is separately provided. You can. In the case of Hangeul, switch functions are assigned to the input keys corresponding to the five terminal sounds so that the terminal sounds corresponding to ㄱ, ㄷ, ㅂ, ㅅ, ㅈ can be converted into twin consonants of ㄲ, ㄸ, ㅃ, ㅆ, ㅉ. You can. In addition, by individually assigning the switch function to the 6 short vowels of ㅏ, ㅓ, ㅗ, ㅜ, ㅐ, and ㅔ, you can easily input the double vowels of ㅑ, ㅕ, ㅛ, ㅠ, ㅒ, ㅖ using the switch function. have.

At this time, the characters to which the switch function is applied may vary according to the arrangement of the keyboard in Hangul. For example, when a touch keypad such as a keyboard or a keyboard of the heavens and the earth is used, 11 pairs including ㅘ, ㅙ, ㅝ, ㅝ, ㅞ, 아니라 as well as six pairs of ㅑ, ㅕ, ㅛ, ㅠ, 6, ㅖ You could also set the double vowel as the character to switch to.

In addition, in Japanese, a switch function may be applied to mark characters such as katakana or tactile sounds or tactile sounds for foreign language notation.

In addition, since each country has different features and notation methods for each language, such as Chinese, German, and Spanish, it is possible to set or change various characters to be applied to the switch in consideration of the notation method of the language.

For reference, each step of the text input method may be performed according to the order shown in the drawings, but each step may be performed in a different order unless explicitly stated. In addition, some steps may be performed simultaneously, and some steps may be performed selectively.

Character input method using a touch keypad with an individual switch function according to an embodiment of the present invention is a step of displaying a keypad on a touch screen (S10), a step of displaying a switch function on a character to be switched (S20), a character selected by the user Inputting step (S30), determining whether to use the switch function (S40), converting the character used by the switch function (S50), inputting the converted character (S60), and input of characters It may include a step (S70) of determining whether to terminate.

The step of displaying a keypad on the touch screen (S10) is a step of displaying a touch keypad capable of inputting text on a screen of a mobile communication terminal held by a user. As described above, the touch keypad may be a previously used keyboard, such as a QWERTY keyboard, a heavenly keyboard, or a naratgle keyboard, or any type of keyboard provided later. For example, as illustrated in FIG. 1, it may be Google's mobile short vowel keypad displayed in English or Korean.

The step of displaying the switch function on the switch target character (S20) is a step of individually displaying the switch function on the switch target character that the user can convert to uppercase letters or twins among the input keys of the touch keypad made of input characters. As described above, the switch target character may be configured in various forms, such as uppercase letters in English, double consonants or pairs of Hangul, double vowels, or Japanese tactile sounds. In addition, the display indicating the switch function may be made of a solid red line display, as shown in FIG. 2, or may be formed of an arrow or a shape such as a circle or a square.

The step of inputting a character selected by the user (S30) is a step of receiving a character selected by the user through a touch keypad displayed on the screen and displaying it on the screen. When there is a character to be input on the touch keypad displayed on the screen, the user can input the selected character on the screen by pressing the corresponding character. If a character to be entered, such as a capital letter or a pair of consonants or a pair of vowels, is not present on the touch keypad displayed on the screen, the user may convert a specific letter to a letter to be entered using a switch function.

The step of determining whether to use the switch function (S40) is a step of determining whether or not the user performed an operation corresponding to the switch function with respect to the input key of the switch target character displayed with the switch function. The switch function may be defined as a drag operation in the up, down, left, and right directions, but may also be defined as various types of operations that can be distinguished from an operation of pressing a specific character.

The step of converting a character in which the switch function is used (S50) is a step of converting the character to which the switch is applied, such as capital letters or twins, for the input key in which the switch function is used by the user.

The character of 'ㅂ' is converted to the double consonant of 'ㅃ'.

FIG. 6 is a screen view illustrating a state in which a specific character using a switch function is converted into a switch applied character in a character input method using a touch keypad to which an individual switch function is applied according to an embodiment of the present invention. In the method of inputting a character using a touch keypad to which an individual switch function is applied according to an embodiment of the present invention, it is preferable that the characters converted through the switch function remain in the converted state until the conversion is canceled by the user. Of course, it may be possible to automatically return to the original state after input of the converted character.

The step of inputting the converted character (S60) is a step in which a switch function is used to input characters converted into uppercase letters or twins to be displayed on the screen. At this time, the step (S50) of converting the characters in which the switch function is used to uppercase or twins and the step of inputting the converted character (S60) may be performed by separate operations, but the user uses the switch function. It is also possible to continuously perform the step of converting the character in which the switch function is used by one operation (S50) and the step of inputting the converted character (S60). As described above, when the step (S50) of converting the character used by the switch function and the step of inputting the converted character (S60) are performed simultaneously, conversion and input are simultaneously performed by the user using the switch function operation, so the character You will be able to speed up typing and shorten text entry time.

For example, suppose the user inputs the word 'popo'. When using the existing touch keypad, hold down the shift key with one finger, press the 'ㅂ' input key with the other finger, release the shift key, and press the 'ㅗ' input key to complete the 'po'. Repeat twice. Alternatively, after pressing a switch key such as the up arrow, enter 'ㅃ', release the up arrow again, and then enter 'ㅗ' to complete the 'po' and repeat it twice.

However, according to a method of inputting a character using a touch keypad to which an individual switch function is applied according to an embodiment of the present invention, the corresponding character is converted to '드래그' by dragging the 'ㅂ' input key down, and 'ㅗ' and By entering 'ㅃ' and 'ㅗ', the word 'popo' can be completed simply.
