Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-screen collaboration technologies fail to effectively integrate the capabilities of source and destination devices, limiting users' ability to simultaneously utilize functions provided by both devices during screen projection.
Innovation Solution
A method and system that enables a destination device to display icons of applications from both the source and destination devices, allowing seamless integration and operation of applications across devices, including the transmission of display data and control messages to facilitate cross-screen functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If screen projection is used to display source device content on destination device, then display capability is improved, but device capability integration is limited
Solution Approach 1:
The patent merges the capabilities of source and destination devices by integrating application functions from both devices into a unified interface on the destination device. The system combines source device applications with destination device applications, allowing users to access and operate both sets of applications through a single unified interface, thereby achieving effective capability integration while maintaining display enhancement.
2Illumination intensity
If screen projection is used to display source device content on destination device, then display capability is improved, but simultaneous function usage is limited
Solution Approach 1:
The destination device interface is designed to be universal, supporting both source device applications and destination device applications within the same operational environment. Users can simultaneously access and operate applications from both devices through the unified interface, enabling multi-functionality without requiring separate control mechanisms or switching between different modes.
3Adaptability or versatility
If application functions are integrated on destination device, then adaptability is improved, but system complexity increases
Solution Approach 1:
The patent introduces an intermediary mechanism that manages the integration of applications from source and destination devices. This intermediary layer handles the complexity of capability integration, application launch coordination, and interface management, thereby enabling adaptability improvement while shielding users from underlying system complexity through automated mediation.
Data Source
AI summary
A source device sends, to a destination device, application information of at least one source device application installed on the source device. The destination device displays an icon of the at least one source device application in a first interface, and displays, in the first interface, an icon of at least one destination device application installed on the destination device. In response to an operation performed on an icon of a first application, the destination device obtains first display data generated during running of the first application on the source device. The destination device displays an application window of the first application based on the first display data. In response to an operation performed by the user on an icon of a second application in the destination device application, the destination device starts the second application, and displays an application window of the second application.
