Multi-Screen Interface Projection for Secure Cross-Device Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for cross-device interaction between mobile devices and computers lack efficient and secure methods for establishing connections, file sharing, and seamless user experience, particularly in terms of interface projection and control.
Innovation Solution
A multi-screen interaction method and apparatus that enables direct wireless connections between devices using broadcast information or QR code scanning, allowing for secure and automatic account linking, interface projection with responsive control, and intelligent file transfer through drag-and-drop operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional multi-screen interaction technologies are used, then device connection is established, but user experience is less intuitive and interaction efficiency is reduced
Solution Approach 1:
The patent projects the interface of a second terminal onto the display screen of a first terminal, creating a visual copy of the remote interface. This allows users to see and interact with the second terminal's interface elements (such as file lists, application windows, and control elements) directly on the first terminal's larger or more convenient display, making interactions more intuitive and efficient without requiring constant switching between devices
Solution Approach 2:
The patent introduces a projection mechanism as an intermediary between the first terminal and second terminal. The projected interface serves as a mediator that translates the second terminal's interface elements into a form that can be directly manipulated on the first terminal, enabling seamless cross-device operations without requiring users to physically handle both devices simultaneously
2Ease of operation
If interface projection is implemented, then interaction control is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal interaction mechanism where the first terminal can project and interact with various types of interfaces from the second terminal (file management interfaces, application interfaces, system settings interfaces, etc.). This multi-functional approach consolidates multiple specific interaction scenarios into a single unified framework, reducing the need for separate complex handling logic for each interface type and thereby managing system complexity more effectively

AI summary
Provided are a multi-screen interaction method and apparatus, and a storage medium. The method includes that: a first interface of a second terminal is projected on a display screen of a first terminal; detection is performed on a first operation acting on the first interface; and responsive to the first operation on a first object in the first interface is detected, the first operation on the first object is responded in the first terminal. Through the method, the interaction between different terminals is enhanced.
