Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-device interaction technologies lack efficient methods for seamless and intelligent interaction between devices, particularly in scenarios where user operations on one device control another, leading to suboptimal user experience and inefficient file transfer.
Innovation Solution
A multi-screen interaction method and apparatus that projects a second terminal's interface onto a first terminal, allowing the first terminal to detect and respond to user operations, enabling direct control and file transfer between devices through operations like dragging and copying, with support for wired and wireless connections, including USB, Bluetooth, and NFC.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional multi-device interaction technologies are used, then device connection is established, but user experience is suboptimal and interaction efficiency is low
Solution Approach 1:
The patent projects the interface of a second terminal onto a first terminal, creating a visual copy of the remote device's interface. This allows users to see and interact with the second terminal's interface on the larger first terminal screen, enabling seamless control without switching devices. The copying principle resolves the contradiction by maintaining operational simplicity while significantly improving interaction efficiency through centralized control.
Solution Approach 2:
The first terminal acts as an intermediary device between the user and the second terminal. By projecting the second terminal's interface onto itself and detecting operations on this projected interface, the first terminal mediates control operations, translating user actions into commands for the second terminal. This intermediary role improves both ease of operation and interaction efficiency by providing a unified control point.
2Productivity
If manual operations on both devices are required, then device control is achieved, but file transfer efficiency is reduced
Solution Approach 1:
By projecting the second terminal's interface onto the first terminal, the patent enables users to perform file operations on the projected interface using the first terminal's input devices. This copying approach eliminates the need for manual operations on both devices simultaneously, as all control can be performed from the first terminal, thereby improving file transfer efficiency while maintaining operational simplicity.
Solution Approach 2:
The system enables self-service operation where the first terminal automatically detects operations performed on the projected interface and translates them into appropriate commands for the second terminal. This self-service mechanism reduces manual intervention requirements and improves file transfer efficiency by automating the coordination between devices.
3Extent of automation
If interface projection and operation detection are implemented, then interaction intelligence is improved, but device complexity increases
Solution Approach 1:
The first terminal is designed to perform multiple functions: it serves as both the user interface device and the control mediator. By projecting the second terminal's interface onto itself and detecting operations on this projected interface, the first terminal universalizes its role, handling both display and control functions. This multi-functionality improves interaction intelligence without significantly increasing overall system complexity, as it utilizes existing terminal capabilities.
Solution Approach 2:
The patent merges the functions of interface display and operation detection into a single device (the first terminal). By combining these functions that could be distributed across multiple devices, the system improves interaction intelligence through centralized processing while actually reducing overall system complexity. The merging principle allows the first terminal to handle both projection and detection tasks, simplifying the architectural design.

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.
