1. the method for characters by touch screen input, it is characterized in that, each analogue-key on the soft keyboard of touch-screen is divided at least two zones, the corresponding character in each zone, the mapping relations of storing each zone corresponding coordinate range parameter, the corresponding amplifying parameters of each analogue-key that sets in advance and each zone and character in soft keyboard on each analogue-key, the analogue-key;

  • Obtain the initial position coordinate parameters of initial input operational correspondence;

    Determine the affiliated analogue-key of initial input operation according to the initial position coordinate parameters that obtains, amplify this analogue-key according to the amplifying parameters of this analogue-key that sets in advance;

    Obtain and stop final position coordinate parameters corresponding to input operation;

    Determine input character according to the final position coordinate parameters.
