Unified Interface for Cross-Device File Transfer in Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In projection scenarios, existing data transmission methods require users to perform multiple operations to share application data between devices, leading to low data sharing efficiency and increased user complexity.
Innovation Solution
A method that allows direct sharing of application data between devices without repeatedly switching user interfaces, by detecting and interpreting specific operations on one device and sending corresponding instructions and information to the other device for seamless data transfer and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user follows the existing data transmission method to insert a picture into a word document, then the picture can be transferred from the mobile phone to the laptop, but the user needs to perform multiple operations including opening Word application, selecting insert option, finding the picture from preset storage address, and adding the picture
Solution Approach 1:
The patent combines the file selection interface and the target application interface into a single unified interface displayed on the large screen device. The user can directly drag and drop files from the projected mobile phone interface to the target application window without switching between multiple applications or interfaces, merging the file transfer process with the application usage process.
Solution Approach 2:
The large screen device acts as an intermediary between the mobile phone and the target application. It receives the drag and drop operation from the user, identifies the source file on the mobile phone, retrieves the file, and automatically inserts it into the target application, mediating the entire file transfer process without requiring the user to manually navigate through storage directories.
2Productivity
If the user wants to insert the picture into a word document, then the picture can be transferred and displayed in the word document, but the user needs to switch between different user interfaces multiple times
Solution Approach 1:
The patent merges the file browser interface and the target application interface into a single unified display. The user can perform the entire file insertion operation within one interface context, eliminating the need to switch between file management interfaces and application interfaces, thus improving operational efficiency.
3Ease of operation
If the existing drag and drop method is used, then data can be transmitted between devices, but the data sharing efficiency is relatively low due to multiple required operations
Solution Approach 1:
The system performs preliminary actions by automatically identifying the source file when the user initiates a drag and drop operation. The large screen device pre-loads the file information and prepares the target application to receive the file, so that when the user releases the drag operation, the file is already ready for immediate insertion, eliminating the need for subsequent manual steps like navigating to storage locations or selecting insert options.

AI summary
The method includes: in a projection scenario, a first device displays, in a first display area of a display, a first user interface of a first application running on the first device, and displays, in a second display area of the display, a second user interface that is being displayed by a second device. The second user interface includes one or more file objects. A user may drag a first file object on the second user interface to the first user interface to release, so that the second device transfers the first file object to the first device. Then, the first device stores the first file object, and provides the first file object for the first application for processing. In embodiments, application data of one device can be directly shared to an application of another device without switching a user interface for a plurality of times.
