Abstract
A character entry method and apparatus in a terminal in which characters are grouped into a plurality of character sets and a representative character of each of the character sets is imprinted on a respective key are provided. In the character entry method, when a key imprinted with a representative character is pressed, characters belonging to a character set represented by the representative character are displayed. When a directional key is pressed, the number or duration of key presses of the directional key is counted or measured. A character corresponding to the number or duration of key presses is selected among the displayed characters and entered.
Claims26
A character entry method in a terminal in which characters are grouped into a plurality of character sets and a representative character of each of the character sets is imprinted on a respective key, comprising the steps of:
- displaying, when a key imprinted with a representative character is pressed, characters belonging to a character set represented by the representative character;
- counting, when a directional key is pressed, the number of key presses of the directional key;
- and
- selecting a character corresponding to the number of key presses among the displayed characters and entering the selected character.
A character entry apparatus in a portable terminal, comprising:
- a keypad having a plurality of keys wherein characters are grouped into a plurality of character sets and a representative character of each of the character sets is imprinted on a respective key of the plurality of keys;
- a display for, when a key imprinted with a representative character is pressed, displaying characters belonging to a character set represented by the representative character;
- and
- a controller for when a directional key is pressed, counting the number of key presses of the directional key, selecting a character corresponding to the number of key presses among the displayed characters, and entering the selected character.

- displaying, when a key imprinted with a representative character is pressed, characters belonging to a character set represented by the representative character;
- measuring, when a directional key is pressed, the duration of the key press of the directional key;
- and
- selecting a character corresponding to the key press duration among the displayed characters and entering the selected character.
A character entry apparatus in a portable terminal, comprising:
- a keypad having a plurality of keys wherein characters are grouped into a plurality of character sets and a representative character of each of the character sets is imprinted on a respective key of the plurality of keys;
- a display for, when a key imprinted with a representative character is pressed, displaying characters belonging to a character set represented by the representative character;
- and
- a controller for when a directional key is pressed, measuring the duration of the key press of the directional key, selecting a character corresponding to the key press duration among the displayed characters, and entering the selected character.
A computer-readable recording medium having recorded thereon a program for character entry for a terminal, comprising a plurality of keys including directional keys, in which characters are grouped into a plurality of character sets and a representative character of each of the character sets is imprinted on a respective key, comprising:
- a first code segment, for causing a computing device to display, when a key imprinted with a representative character is pressed, characters belonging to a character set represented by the representative character;
- a second code segment, for causing a computing device to count, when a directional key is pressed, the number of key presses of the directional key;
- a third code segment, for causing a computing device to select a character corresponding to the number of key presses among the displayed characters and entering the selected character.
