Keypad device of mobile communication terminal and input method thereof

Abstract

The present invention relates to a keypad device of a mobile communication terminal and an input method thereof. In the present invention, in order to improve the speed of inputting the english characters, english characters having a higher frequency are provided in positions where characters are convenient to be input by analysing english character frequency based on the code theory, and in order to make the input of URL easy, an additional function for inputting special characters and continuous characters easily is provided. In the present invention, the english characters are allocated according to that if the position of the key is easy to be input based on the occuring frequency of the english characters in the code theory, and in the positions of the keys 3, 6, 9, # which are not convenient for inputting are allocated with english characters having lower frequency to make the input of english characters more convenient for the users of the mobile communication terminal. Furthermore, blank space key is provided in the keypad through which blank space can be input, also a copy key is provided for inputting through copy when users input characters, and a reverse key is also provided for inputting characters in the reverse order of the english characters allocated according to the figure keys. As a result, the input operation of processing english characters is more effective.

Description

technical field [0001] The present invention relates to a mobile communication terminal, in particular to a keypad device of a mobile communication terminal and an input method thereof. In order to speed up the input operation of English characters, according to the analysis of the frequency of English letters used in cipher theory, it is placed at a convenient input position. English characters with high frequency are set on it, and an additional function for easy input of special characters and continuous character input is provided for easy URL input. Background technique [0002] Generally, a keypad used in a mobile communication terminal is composed of simple keys mainly used for inputting a telephone number during a call operation, connecting to other mobile communication services, or operating the mobile terminal. In addition, multiple characters of Korean and English are used for mapping (mapping) to one key for character input. [0003] Also, in other small mobile ...

Problems solved by technology

[0012] And, because the English words and special characters are listed in sequence in the number keys for distribution, when using one hand to input English words, if you want to input the English words distributed in the 3, 6, 9, # keys near the inner side of the above-mentioned keypad 24 will be more difficult

[0013] In the keypad of the mobile communication terminal of the prior art, on the English input operation, because the English word is distributed among each button successively, the English word with high frequency of occurrence is positioned at the arbitrary position of each button, makes need to carry out unnecessary input operation And increase the input time and the number of keystrokes

Simultaneously, when using the WAP (Wireless Application Protocol) browser, due to the specific character "w" or the special character ": / ." etc. that are more used in the input of URL etc. are arranged in sequence in the button, make need spend more input time

[0014] And, in order to continuously input the same text, it is necessary to wait for a certain period of time to end the input operation and move the cursor to the next input position, or use the navigation key to operate so that the next input operation can be performed and then input the corresponding text, so that in the input operation takes unnecessary time or requires unnecessary actions
