US 2012/0235838 A1 · METHOD AND DEVICE FOR CHARACTER INPUT BY DIECTION KEY

Abstract

A method and a device for character input by direction key are disclosed. The method comprises: a mapping relation between characters in input character set and direction key input sequences is constructed, and at least a code table representing the mapping relation is established; the character is inputted by a code table selection key and a direction key, the character input comprises the following steps: a code table as a current code table is determined according to the input of a code table selection key (S10); a prompting message of the current code table is displayed on a display screen (S20); an input character is determined in the current code table according to a direction key input sequence (S30). The used direction key, the confirmation key and the code table selection key are based on an existing key of an existing e-book reader, media player and other electronic devices.

a characters is input by code table selection keys, arrow keys and a confirmation key, the method for character input comprises the following steps:
P10) to detect whether there is any new key input;
if no, keep on waiting;
if yes, go to the next step;
P20) to judge the type of the key input and execute the following operations respectively according to the type:
when code table selection keys are input, to switch the current code table according to the key input and control the display screen to display the prompt message of the current code table, then go back to the step of P10;
when a arrow key is input, to recognize the key-value of the arrow key input and update the sequence of arrow keys input accordingly;
to select a current character in the current code table according to the sequence of arrow keys input and then go back to the step of P10;
when the Confirmation key is input, to confirm that the current character is the character input and go to the end of the process to input a character;

6 more elements

A device for character input by arrow keys comprises a character input module and a group of keys input, a display screen and a memory that communicate with the character input module, characterized in that:

the group of keys input comprises at least one code table selection key, a plurality of arrow keys and at least one confirmation key;
the content to control the display screen and the character input module to execute the following steps is stored in the memory:
S10:
to confirm the current code table according to the input of the code table selection key;
S20:
to display the prompt message of the current code table on the display screen;
S30:
to confirm the character input in the current code table according to the sequence of arrow keys input.
