File Opening by Operation Location in Multi-Screen Collaboration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-screen collaboration scenarios, users cannot conveniently open files on the device they intend to view without exiting the collaboration mode, requiring complex steps.
Innovation Solution
A method where a first device detects user operations on its display or a second device's display to determine which device to open the file, allowing local opening on the first device if the operation is on its display and remote opening on the second device if on the second display, with metadata synchronization for file access and updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a file is opened on the second device (PC) with larger display area, then the viewing effect is improved, but the user cannot view the file on the first device (mobile phone) without exiting multi-screen collaboration mode, requiring complex steps
Solution Approach 1:
The system dynamically determines which device should open the file based on real-time detection of user operation location. When the user operates on the first device's display, the file opens on the first device; when the user operates on the second device's display, the file opens on the second device. This dynamic adaptation resolves the contradiction by making the file opening behavior flexible rather than fixed, allowing the system to provide both large-screen viewing capability and convenient file access on the mobile device depending on user context.
2Illumination intensity
If the file is always opened on the second device, then the viewing effect is improved, but the response time and power consumption increase due to remote operation handling
Solution Approach 1:
The system enables the first device to handle file opening operations locally when the user interacts with the first device's display, eliminating the need to transmit operations remotely to the second device. This self-service capability reduces response time and power consumption for operations that can be performed locally, while still maintaining the option to open files on the second device when large-screen viewing is needed.
3Ease of operation
If the system detects user operation location and routes file opening accordingly, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The system uses an intermediary mechanism (the multi-screen collaboration framework) that already exists to detect user operations and coordinate between devices. By leveraging this existing intermediary infrastructure, the system can determine operation location and route file opening requests appropriately without adding significant complexity, as the intermediary already handles cross-device communication and coordination.

AI summary
This application relates to a file opening method and a device. A first device displays a first interface, and projects the first interface onto a second interface of a second device, where the first interface includes at least one file icon, the second interface includes the first interface, and a file corresponding to the at least one file icon is stored in the first device. The first device detects an operation performed on the file icon. When the file icon is an icon displayed on the first interface, the first device invokes a first application to open the file; or when the file icon is an icon displayed on the second interface, the first device sends metadata of the file to the second device, where the metadata of the file is used to open the file on the second device.
