Method and system for switching into irregular polygon area in display screen

The invention relates to the technical field of IoT (Internet of Things), in particular to a method and a system for switching into an irregular polygon area in a display screen. By the method and the system, meanings of gestures of users can be conveniently identified and according to different meanings of the gestures of the users, the irregular polygon area in the designated display screen can be switched into in a wireless remote control manner. The method for switching into the irregular polygon area in display screen is characterized in that after a handheld mobile smart device identifies the meaning of the gesture and generates a corresponding signal, the signal is sent to a non-touch large screen control device in a wireless transmission manner, and after the non-touch large screen control device switches a current selected area in the display screen into the designated irregular polygon area after receiving the gesture meaning signal. The system for switching into the irregular polygon area in the display screen is characterized by comprising a wireless router, the handheld mobile smart device and the non-touch large screen control device, wherein the handheld mobile smart device is connected to the non-touch large screen control device in a wireless manner by the wireless router.
