Abstract
An apparatus for inputting letters in an electronic device, which can select and input letters in guide screens showing multiple letter groups linked to each other in a tree structure by using only two direction keys and an enter key, and a method thereof are provided. Accordingly, without installing a keyboard in an electronic device, it is possible to simply input letters on a screen using only two direction keys and an enter key in on-screen display letter input menu screens, by dividing letters into sub groups in a tree structure.
Claims21
An apparatus for inputting letters in an electronic device, the apparatus comprising:
- a key input unit which selects a letter input mode and inputs commands necessary to input letters;
- a memory which divides letter information into multiple groups, stores the information of each of the multiple groups, and stores menu screen information for guiding inputting of letters, according to a tree structure;
- a controller which controls the memory in response to key commands input from the key input unit, sequentially reads the menu screen information for selecting an uppermost letter group to a lowermost letter group from the memory, reads the information of a letter selected from the lowermost letter group from the memory, and controls the letter information displayed on a letter input window;
- and
- a graphic data processor which graphically processes the menu screen information and letter information and performs the processed information to be output as image signals.
A method for inputting letters in an electronic device comprising:
- (a) dividing letters into multiple groups, storing information of each of the groups, and storing menu screen information for guiding inputting of letters according to a tree structure;
- (b) sequentially outputting the menu screen information for selecting an uppermost letter group to a lowermost letter group in response to key commands;
- and
- (c) generating image signals corresponding to a letter selected in the menu screen information of the lowermost letter groups.
