Adaptive Multi-Screen Interface Projection Based on Input Source
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-screen collaboration methods in electronic devices, such as between PCs and mobile phones, often divert user attention and compromise privacy as they always project the mobile phone's display onto the PC, even when the user is directly interacting with the mobile phone.
Innovation Solution
Implementing a display method where the second terminal (e.g., mobile phone) determines the input source and selectively projects or displays interfaces based on the input device used, allowing the user to control which interface is shown on which device, thereby protecting privacy and reducing attention diversion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display interface of the mobile phone is always projected onto the display of the PC for display, then the user can perform operations on the mobile phone at the PC end, but user privacy is compromised and user attention is diverted
Solution Approach 1:
The patent implements dynamic control of interface projection based on input source detection. When the input source is the PC's input device, the mobile phone interface is projected onto the PC display. When the input source is the mobile phone's own input device, the projection is suspended or switched to a different interface. This dynamic adjustment resolves the contradiction by making the projection behavior adaptive to the current interaction context, thereby protecting privacy while maintaining operational convenience.
2Ease of operation
If the display interface of the mobile phone is always projected onto the display of the PC for display, then the user can perform operations on the mobile phone at the PC end, but user attention is diverted between devices
Solution Approach 1:
The patent employs feedback mechanisms by detecting the input source and using this information to control the projection state. The system continuously monitors whether the input comes from the PC or mobile phone, and adjusts the projection accordingly. This feedback loop eliminates unnecessary projection when the user is directly interacting with the mobile phone, thereby reducing attention switching and improving collaborative use efficiency.
3Adaptability or versatility
If the display interface of the mobile phone is always projected onto the display of the PC for display, then multi screen collaboration is achieved, but the system complexity increases
Solution Approach 1:
The patent applies local quality by making the projection behavior context-specific rather than uniform. Different projection behaviors are applied based on the local condition of input source: full projection when PC input device is used, no projection when mobile phone input device is used. This localized approach maintains multi-screen collaboration capability while simplifying the overall control logic by using clear, condition-based rules.
Data Source
AI summary
A method includes a second terminal that displays a first interface, and receives a first operation of a user on content on the first interface. The second terminal sends data to a first terminal in response to the first operation when an input source of the first operation is an input device of the first terminal, where the data is used by the first terminal to display a second interface on a display of the first terminal. The second terminal displays the second interface on a display of the second terminal in response to the first operation when the input source of the first operation is an input device of the second terminal.
