Description

  The present invention relates to a touch screen keypad array such as a portable terminal, and more particularly, can efficiently input Japanese characters on a touch screen keyboard for inputting characters in a portable terminal such as a cellular phone and a PDA. To a touch screen keypad array.

  A mobile terminal represented by a mobile phone can be classified into a feature phone having a physical keypad and a smartphone having a touch screen virtual keypad according to a key input method.

  General feature phones mainly use a method of inputting characters using 12 keys, and some smartphones use a method of inputting using a 26-key qwerty keyboard. is doing.

  However, in the case of a Qwerty keyboard for a smartphone, the size of one key is very small and the interval between keys is narrow, so that there is a problem that fast input is difficult.

  The present invention prevents the key size on the LCD screen of the smartphone from becoming excessively small by configuring the keypad of the touch screen in 4 rows and 5 columns, and at the same time, ensures the number of keys that are inconvenient for input. Furthermore, it is intended to input Japanese characters easily with fewer touches.

  In a language with a kanji structure such as Korean or English, it is relatively easy to input characters by combining letters of the corresponding language, but in Japanese, kana is not a combination of kana. Since characters are formed by a typical transformation, it is difficult to input.

  Therefore, conventionally, pronunciation corresponding to Japanese kana is first entered in English using a keypad array (K) having a normal alphabet arranged on a mobile terminal represented by a mobile phone (M). Then, it is converted and input by operating the conversion selection key.

  However, such a conversion method requires a considerable input time, and it is very difficult for a user who is not familiar with the alphabet, and there is a problem that character input is not easy.

  It is an object of the present invention to provide a touch screen Japanese keypad array having an input method that matches Japanese character characteristics.

  Another object of the present invention is to provide a touch screen Japanese keypad array in which a user can easily learn a character input method and the efficiency of character input is improved.

  In order to achieve the above object, the Japanese touch screen keypad array of the mobile terminal according to the present invention is a Japanese touch screen in which characters are input by a touch screen method with a virtual keyboard displayed on the screen. In the keypad array, five immediate input keys that display “A”, “I”, “U”, “E”, “O” in the initial state, and “KA”, “SA”, “ Nine selection input keys for displaying “ta”, “na”, “ha”, “ma”, “ya”, “ra”, “wa”, and selection for entering the final selected character When the selection input key is operated, the following character group corresponding to the character of the selected selection input key is displayed on the immediate input key, and when the immediate input key is operated in that state, The character displayed on the immediate input key is entered And wherein the door.

  At this time, according to the number of times the selection input key is operated repeatedly, each character corresponding to the character group of the selection input key is displayed on the operated selection input key, and by pressing the selection key in that state, It is desirable to finally input the characters displayed on the selection input key.

  Preferably, the keypad array has an arrangement of 4 rows and 5 columns, and the immediate input keys are arranged in one row.

  More preferably, the selection input keys are arranged in 2 columns to 4 columns of 2 rows to 4 rows.

  The Japanese keypad array according to the present invention includes a kana conversion key for converting hiragana and katakana, a mode conversion key for converting to a numeric or alphabet input mode, and a special character input mode. It is desirable to further include a special character key, a backspace key for deleting the last input character, and a muddy sound ('), a semi-voiced sound (°), a full-width character, and a half-width conversion key for converting to a half-width character. .

  In addition, when the selection key is operated in an initial state, it is preferable that a space is input.

  A touch screen keypad array such as a portable terminal according to the present invention provides a unified intuitiveness by minimizing the number of times of input so that a user can input characters more easily than conversion by conventional alphabet input. This has the effect of maximizing the utility of character input.
