Problems solved by technology

[0004] At this stage, the implementation of screen projection technology can be roughly divided into two methods, namely wired and wireless; in the wired method, the user must use the video conversion cable to connect the two devices, and project data through the video conversion cable. This method causes users to be easily bound by cables during use, inconvenient to move, and user experience is not good; In the startup state, the setting path of the "multi-screen interaction" is relatively cumbersome, and the user experience is not good

Abstract

The invention provides a wireless projection screen method and device. the wireless projection screen method includes: responding to an input operation triggered by a user for a preset functional item of a physical key of the intelligent device, and starting an intelligent operation system of the intelligent device to process input of the preset functional item, wherein the preset functional item can trigger a wireless projection screen service; acquiring first key value information of the user corresponding to the input of the preset functional item; converting the first key value information into second key value information which can be recognized by the intelligent operation system through a pre-established mapping file; and instructing the intelligent operation system to start the wireless projection screen service according to the second key value information so as to allow another intelligent device to detect the wireless projection screen service to achieve wireless projection screen. The technical scheme can meet an operation habit of the user for the intelligent device, can rapidly trigger the wireless projection screen service, can save complex operation paths, can simplify a user operation, and cn improve the user experience of projection screen.

Description

technical field [0001] The present application relates to the technical field of screen projection, and in particular to a wireless screen projection method and device. Background technique [0002] With the development of Internet technology, many devices in people's daily life are gradually transformed into smart devices, such as smart TVs, smart projectors, smart phones, etc.; An intelligent part hardware module is added in the system, and the intelligent part hardware module generally includes a processor, a memory, a storage device, an interface and the like. [0003] The wide application of smart devices has led to the gradual development of screen projection technology. The essence of screen projection technology is screen mirroring technology, which can send resources (such as photos, music, videos, PPT and other multimedia content, etc.) on one device to another. Technology for displaying on a device screen. Screen projection technology has been widely used in man...
