Screen Projection Control via Bidirectional Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screen projection technologies limit the ability of a target device, such as a computer, to adjust or control the display mode or content of a projected screen from another device, like a mobile phone, preventing it from meeting user needs in various application scenarios.
Innovation Solution
A processing method and device that establish a connection channel with a target device, acquire a target instruction based on a target operation, and send target display content to the target device for output in a target window, allowing the target device to control and adjust the screen projection mode and content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile phone projects its screen to a computer using existing screen projection technology, then the content can be displayed on the computer screen, but the computer cannot adjust the display mode or content of the projected screen
Solution Approach 1:
The patent implements a feedback mechanism where the computer receives projection content from the mobile phone and simultaneously sends control instructions back to adjust the display mode and content. This bidirectional communication enables the computer to actively control the projection rather than passively receiving it, resolving the contradiction between adaptability and ease of operation.
Solution Approach 2:
The patent makes the computer serve multiple functions: it acts as both the display device and the control device. The computer can receive projection content, adjust display modes, and control content presentation, thereby enhancing its versatility while simplifying the user experience by consolidating control capabilities in one device.
2Adaptability or versatility
If the computer passively receives and displays projected content, then the projection function is achieved, but the computer cannot meet user needs in different application scenarios
Solution Approach 1:
The patent introduces dynamic adjustment capabilities where the display mode and content can be changed in real-time based on user needs. The system can switch between different projection modes (e.g., mirror mode, capture mode, extended mode) and adjust content dynamically, enhancing adaptability to different application scenarios without requiring complex manual configuration.
Solution Approach 2:
The patent enables the system to automatically detect and adapt to different usage scenarios. The computer can autonomously adjust display parameters and content presentation based on the detected scenario, reducing the need for complex user intervention while maintaining high adaptability to various application needs.

AI summary
A processing method includes establishing a connection channel with a target device including a target screen; acquiring a target instruction based on a target operation acquired by the target device; acquiring target display content in a screen projection mode specified by the target instruction; and sending the target display content to the target device through the connection channel. The target screen outputs the target display content in a target window.
