Selective Screen Mirroring for Privacy and Notification Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen sharing technologies in electronic devices, such as mirroring to external devices, face challenges in protecting user privacy and ensuring important notifications are not missed, while allowing concurrent use of other device functions.
Innovation Solution
An electronic device with a processor that identifies configured conditions based on events, such as sender history or user input, to selectively mirror only the execution screen of an application instead of the full screen, and optionally display notifications, using a pop-up screen format.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If full screen mirroring is transmitted to external device, then screen sharing function is provided, but user privacy is exposed and important notifications may be missed
Solution Approach 1:
The patent segments the screen content by identifying and separating important elements (notifications, key application areas) from general content. The processor analyzes the screen to determine important areas and transmits only those segmented regions to the external device, rather than mirroring the entire screen. This resolves the contradiction by providing screen sharing functionality while protecting privacy through selective content transmission.
Solution Approach 2:
The patent applies local quality by transmitting different quality levels or levels of detail for different regions of the screen. Important areas such as notifications and key application interfaces are transmitted with high fidelity, while less critical areas are either omitted or transmitted with reduced detail. This allows the screen sharing function to operate effectively while minimizing privacy exposure through differentiated content transmission.
2Object-affected harmful factors
If notification is configured not to be displayed during mirroring for privacy protection, then privacy is protected, but important notifications may be missed
Solution Approach 1:
The patent employs preliminary action by proactively identifying and prioritizing important notifications before they are displayed on the external device. The processor analyzes incoming notifications in advance, determines their importance based on predefined criteria (such as application type, sender, or user preferences), and ensures they are transmitted to the external device even when notification display is otherwise restricted. This resolves the contradiction by protecting general privacy while ensuring critical notifications are reliably delivered.
3Loss of information
If full screen is mirrored to external device, then complete screen content is shared, but device functions cannot be used concurrently without interrupting screen sharing
Solution Approach 1:
The patent applies dynamics by making the screen sharing content adaptive and changeable in real-time. The processor continuously monitors the screen for important elements and dynamically adjusts which areas are transmitted to the external device. When the user needs to use other device functions, the system can dynamically switch between transmitting full screen content and transmitting only important areas, allowing concurrent function usage without permanently sacrificing screen sharing quality.

AI summary
An electronic device is provided. The electronic device includes a communication module, a display, and at least one processor operatively connected to the communication module and the display, wherein the at least one processor is configured to, in a state that full screen information on, for mirroring, a full screen displayed on the display is transmitted to an external device via the communication module, identify whether at least one configured condition is satisfied, based on an event occurring, and based on the at least one configured condition being satisfied, transmit, to the external device, information on an execution screen of at least one application among execution screens of applications being displayed on the display, in replacement of the full screen information so as to mirror only the execution screen of the application.
