Abstract

A system and method for interacting multi-screen in a car are presented. A memory of a main device is configured to form a main frame buffer corresponding to the main device and to form at least one secondary frame buffer corresponding to the at least one secondary device. The memory is further configured to form a frequently executed icon frame buffer corresponding to a frequently executed icon to store a user interface image when the controller is performing function of the frequently executed icon. A user interface is used to select a touch screen icon and frequently executed icon for the touch screen to be directed to a corresponding frame buffer and immediately display and control images in the corresponding touch screen to improve the interaction between touch screens.
