Abstract: A Chinese input method in a mobile device comprising a touch screen, the method comprise classifying a plurality of initial icons into initial icon groups according to a predetermined criteria and arranging the initial icon groups on a virtual keyboard of the touch screen to display an initial icon keyboard, determining one or more of the plurality of the initial icons as initial icon input based on touch input on the initial icon keyboard, arranging a plurality of final icons on the virtual keyboard of the touch screen to display a final icon keyboard and determining one or more of the plurality of the final icons as final icon input based on touch input on the final icon keyboard.

Abstract: The present invention relates to an information input system and method using an extension key. The information input system comprises: an input unit including a plurality of divided regions, for detecting a user selected divided region among the plurality of divided regions; and an input analysis unit for allocating corresponding information to the plurality of divided regions, and analyzing, if the input unit detects a user selected divided region among the plurality of divided regions, whether or not information allocated to the divided region is input. The input analysis unit allocates an extension key to at least one divided region out of the plurality of divided regions; and once the extension key is selected, the input analysis unit allocates new information to an extended region which is a divided region determined according to the extension key.

Abstract: A virtual keyboard input system using a pointing device in a digital device. The virtual keyboard input system includes: a sensor unit sensing a contact and a two-dimensional contact position; a switch unit; and a control unit dividing a contact sensitive region of the sensor unit into multiple division regions according to XY coordinates, assigning virtual keys of a virtual keyboard to the division regions, and when the switch unit is turned on, controlling an input of information for a virtual key assigned to a division region which is contacted among the division regions.
