Text-input device and method
First Claim
1. A text-input device comprising:
- a display unit that displays a user interface, which is divided into a plurality of individually presented areas each area including a plurality of cells where predetermined text is displayed;
an input unit that includes a plurality of text-input units to provide a focus moving signal that moves a focus to select a predetermined cell in one of the plurality of individually presented areas and a selecting signal that selects the focused cell, each of the plurality of text-input units corresponding to a different one of the individually presented areas;
a user interface providing unit that generates a control signal corresponding to the selected cell with reference to a mapping table according to whether the selecting signal is available; and
a control unit that performs a control command based on the control signal,wherein the plurality of text-input units includes a first text-input unit corresponding to an area of the individually presented area in which the focus is currently located, and a second text-input unit not corresponding to the area, andwherein the focus moves to an individually presented area corresponding to the second text-input unit when the focus moving signal is provided from the second text-input unit.

11. A method of operating a portable electronic device, comprising:
-
displaying a user interface divided into a plurality of individually presented areas, each area including a plurality of cells where a predetermined text is displayed, receiving a focus moving signal that moves a focus to select a predetermined cell in one of the plurality of individually presented areas and a selecting signal that selects the focused cell from a plurality of text-input units, each of the plurality of text-input units corresponding to a different one of the individually presented areas, creating a control signal corresponding to the selected cell with reference to a mapping table according to whether the selecting signal is available, and performing a control command based on the control signal, wherein the plurality of text-input units includes a first text-input unit corresponding to an area of the individually presented areas in which the focus is currently located, and a second text-input unit not corresponding to the area, and wherein the focus moves to an individually presented area corresponding to the second text-input unit when the focus moving signal is provided from the second text-input unit. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A method of inputting a letter into a device that is capable of supporting at least two modes, each mode displaying one of first and second text areas from which to choose the letter, the method comprising:
-
setting the device into the one of the modes that includes the letter; when a first input key is pressed, inputting a second selecting signal if the letter is included within a second text area of the mode and is focused on; when the first input key is manipulated directionally and the letter is included within a first text area of the mode, inputting a first directional signal to move the focus from a secondary letter to the letter if the letter is not initially focused on when a text area changing signal is input; when a second input key is pressed, inputting a first selecting signal if the letter is included within a first text area of the mode and is focused on; when the second key is manipulated directionally and the letter is included within the second text area, inputting a second directional signal to move the focus from a secondary letter to the letter if the letter is not initially focused on when the text changing signal is input; when the first input key is manipulated directionally and the letter is included within the second text area, inputting the text area changing signal to change a focus to a predetermined cell in the first text area; and when the second input key is manipulated directionally and the letter is included within the first text area, inputting the text area changing signal to change a focus to a predetermined cell in the second text area. - View Dependent Claims (21, 22, 23, 24, 25, 26)
