Screen Projection App Switching Without Display Interruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen projection technologies require users to manually switch between applications on the screen projection display device, which is inefficient and lacks a seamless method for application switching.
Innovation Solution
A method and apparatus for a mobile terminal that allows users to select and project content from an application selection interface, enabling direct switching of applications without exiting the current screen projection, using gestures or touch inputs to control application projection on a larger display device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If users manually switch between applications on the screen projection display device, then application switching can be achieved, but the operation efficiency is low and the process is cumbersome
Solution Approach 1:
The patent segments the application switching process into two independent parts: the source application (first application) and the target application (second application). By separating these functions, the system can maintain the current projection while independently selecting and projecting content from different applications, enabling efficient switching without interrupting the current display.
Solution Approach 2:
The patent introduces a screen projection control interface as an intermediary between the user and the application switching process. This intermediary provides a unified control mechanism that allows users to select target applications without manually navigating through multiple interfaces, thereby improving operation convenience and switching efficiency.
2Productivity
If users exit the current screen projection to switch applications, then application switching is possible, but the current projection is interrupted and time is lost
Solution Approach 1:
The patent implements preliminary action by allowing the system to prepare and select target applications in advance while the current projection continues. The screen projection control interface enables users to pre-select applications without interrupting the ongoing projection, and the system can switch between applications seamlessly based on pre-established selections.
Solution Approach 2:
The patent ensures continuity of useful action by maintaining the current screen projection while simultaneously enabling application switching. The system projects content from both the first application (current) and second application (selected) concurrently, allowing uninterrupted projection while achieving application switching through the screen projection control interface.
3Ease of operation
If a unified application selection interface is provided, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a screen projection control interface that serves multiple functions: it controls application selection, manages projection switching, and provides unified access to both source and target applications. This multi-functional interface reduces the need for separate control mechanisms for each application, simplifying the overall system structure while improving usability.
Data Source
AI summary
A screen projection display method and apparatus, a mobile terminal, a storage medium, and a program product. The method comprises: when the interface content of a first application program is displayed on a screen projection display device, receiving a first instruction (201); in response to the first instruction, displaying an application selection interface, the application selection interface comprising an option of at least one second application program (202); receiving a second instruction for a target second application program among the at least one second application (203); and in response to the second instruction, projecting the interface content of the target second application program to the screen projection display device for display (204).
