PURPOSE: A method for inputting a character through a keyboard automatic conversion is provided to input a word in an information terminal rapidly and conveniently by automatically changing a consonant/vowel active window and adopting an initial sound and vowel simultaneous input method according to an input order and an input time of a character for inputting the Korean alphabet. CONSTITUTION: If a user selects a predetermined consonant on a consonant plate of a terminal screen using a pen(201), a time recognition unit judges whether the pen is separated from the consonant(202). If the pen presses the consonant continuously, the time recognition unit controls a keyboard automatic conversion unit, and a corresponding candidate vowel keyboard is activated adjacent to the consonant(204). The user moves a trace to a wanted vowel on the corresponding candidate vowel keyboard on condition that the consonant is pressed(205). In the case that the wanted vowel is a diphthong and an additional trace movement is necessary(206), a trace of the initial sound and the medial sound are drawn, the trace is moved to the second vowel of the wanted diphthong(208), and combines a diphthong corresponded to the initial sound and the medial sound(209), and a character is combined(210). After the character combination, if the pen is separated from the keyboard(211), a consonant keyboard is activated(212). If the user selects a consonant corresponded to a final consonant(213), a completed Korean character is combined(214), and the combined character is output(215).

Word input method and a computer-readable recording medium with program for executing the method

PURPOSE: A method for inputting notes by a gesture on a device using a touch screen is provided to enable a preset mode change function to execute by using a specific gesture based on a notes recognition technology on a device using a touch screen. CONSTITUTION: The device comprises an input part(101) recognizing a gesture inputted by a notes input way, a CPU(102) executing a function of command recognized by the input part, an output part(104) outputting the result of CPU on a touch screen and a storage(103) storing various information. The CPU provides the result to a user by executing the function of recognition mode change gesture previously stored in the storage in case that the information transferred from the input part is an input of recognition mode change gesture. A recognition model for recognition mode change gesture is stored in the storage and the CPU executes the function by determining the function corresponding to the information inputted from the input part from the information stored in the storage.

PURPOSE: A method for providing an advertisement using an application program loading time in a mobile communication terminal using a touch screen is provided to obtain the effect of the advertisement without providing inconvenience to terminal users by providing the advertisement using a short time in which an application program is loaded. CONSTITUTION: If a terminal user clicks an application program selection button, an input means selection window is displayed and the user selects an application program for which the user wishes among lists arranged on the application program selection window(504). If the user selects the application program, a CPU judges whether the selected application program an application program into which an advertisement is inserted(506). If the selected application program the application program into which the advertisement is not inserted, a corresponding application program is executed(508). If the selected application program is decided as the application program into which the advertisement is inserted, the CPU reads a corresponding advertisement from a storing unit and outputs the read advertisement on a touch screen while the application program is being loaded(510).
