The invention relates to a
system with an intelligent terminal as a host, a mouse and a
touch panel at the same time. The
system comprises a display control module, a
mode switching control module and a multifunctional touch plate control module. The display control module is used for detecting whether the
system is externally connected with a displayer and driving the external displayer and an internal display screen to carrying out displaying. The
mode switching control module is used for enabling an intelligent terminal to be switched between a host mode and a terminal mode. The multifunctional touch plate control module is used for simulating the intelligent terminal to the mouse and the
touch panel. An implementation method of the system is that after the intelligent terminal is connected with the external displayer, the intelligent terminal is switched to the host mode, displaying is redirected to the external displayer again, a touch screen of the intelligent terminal and a moving sensor are used for simulating the intelligent terminal to the mouse and the
touch panel of a computer, and meanwhile showing of
virtual mouse keys and a multi-point touch zone on the internal display screen is controlled. The intelligent terminal is changed to be the host system with the mouse / the touch panel, when the intelligent terminal is connected with the external displayer and a keyboard for working, cost for
purchasing the mouse / touch panel can be saved, and carrying is convenient.
