ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a mobile telephone with a character recognition function, and in particular, to a mobile telephone capable of registering and performing functions using a character recognition function, and a method for controlling the same.
2. Description of the Related Art
In general, mobile telephones have various functions, which can be selected by inputting a combination of input keys. However, due to the compactness of mobile telephones, the number of input keys are limited. This limitation creates an inconvenience to users trying to select among the various functions.
To solve this problem, a character recognition mobile telephone containing a touch screen has been proposed. However, in the conventional character recognition mobile telephone, the utility of the character recognition function is limited, for example, to character input for short message transmission. Accordingly, there has been a demand for a character recognition mobile telephone capable of handling the various functions of the telephone.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a character recognition mobile telephone capable of registering and performing various functions using a character recognition function, and a method for controlling the same.
In accordance with one aspect of the present invention, a method for registering function characters in a mobile telephone includes the steps of: upon indication of an off-hook condition, entering a character recognition mode; upon receipt of a function character, selecting a corresponding one of several functions of the mobile telephone and displaying the received function character that matches the selected function; and registering the function character in association with the selected function, when a user inputs a registration key input in response to the displayed function character.
In accordance with another aspect of the present invention, a method is provided for recognizing function characters in a mobile telephone, where the mobile telephone includes a touch screen, a character code storage for storing character codes, a character recognizer, and a function character storage for storing character codes corresponding to functions of the mobile telephone. The method includes the steps of: upon an indication of an off-hook condition, entering a character recognition mode; recognizing touch screen data input from the touch screen using the character recognizer; reading a character code for the recognized character from the character code storage and displaying the read character code; searching the function character storage for a character code identical to the displayed character code, when the touch screen data input is completed; and entering a function mode associated with the character code, when the function character storage has a character code identical to the displayed character code.
In accordance with a further aspect of the present invention, a character recognition mobile telephone is provided which includes a function character storage for registering character codes corresponding to various function modes of the mobile telephone; a touch screen with which a user inputs a desired function character; a character recognizer for generating feature data for the character input from the touch screen and a corresponding character code, and searching the function character storage for a character code identical to the generated character code; and a controller for entering a function mode corresponding to the input character.
