System and method for interacting multi-screen in a car

摘要

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.

1. A system for interacting multi-screen in a car, comprising:
a main device for a driver to use comprising:
a main switch configured to turn on or turn off a power supply of the main device; when the power supply of the main device is turned on, a main touch screen of the main device is configured to display a user interface having a plurality of icons; when an icon is selected from the plurality of icons, a controller of the main device in coordination with a memory of the main device is configured to perform a function of the icon selected to display an image on the main touch screen and output sound using a main sound card of the main device; anda main connection interface configured to input/output video signals through a wired or a wireless connection; and at least one secondary device for a passenger to use each comprising:
a secondary connection interface configured to connect to the main connection interface of the main device through a connecting wire;a secondary switch configured to turn on or turn off a power supply of the secondary device; when the controller of the main device detects the power supply of the secondary device is turned on, the user interface is transferred to a secondary touch screen of the secondary device where the plurality of icons are displayed; when another icon is selected from the plurality of icons, the controller of the main device in coordination with the memory of the main device is configured to perform a function corresponding the another icon selected to display another image on the secondary touch screen and output sound using a secondary sound card of the secondary device; wherein the memory of the main device is configured to form a main frame buffer corresponding to the main device to store a user interface image on the main touch screen when the controller is performing function of the icon selected and at least one secondary frame buffer corresponding to the at least one secondary device, each of the at least one secondary frame buffer is configured to store a user interface image on the secondary touch screen when the controller is performing function of the another icon.
