Abstract

An integrated input system includes a touch sensing unit, a signal processing unit, a user instruction recognizing unit and an integration bus. The touch sensing unit has at least an electrical circuit and a transmission conducting line for outputting a sensing signal after being touched with one or multiple objects. The signal processing unit processes the sensing signal and outputting a press point message. The user instruction recognizing unit analyzes a user instruction, which includes a keyboard message input, a triggering action of a functional key or hot key, a directional input of a touchpad or mouse and a drawing information input of a handwriting board, corresponding to the press point message. The integration bus receives information of an external display unit and transmits the user instruction.
