ABSTRACT:
In a character input method and apparatus, data can be input by a simple operation using a displayed keyboard. The keyboard is displayed on the picture surface of a display unit, and data is input by designating a key position on the keyboard. The designated key position is detected based on a designated coordinate position on the keyboard. The corresponding operation is identified based on coordinate positions subsequently input on the keyboard, and a specific key code is generated based on the detected key position and the identified operation.
