Selective Image Transmission via Drop Area for Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screen mirroring technologies transmit the entire smartphone screen, leading to privacy issues and difficulties in sharing specific content or using the smartphone while sharing the screen with others, such as checking calls or texts during TV viewing.
Innovation Solution
A user terminal with a display unit, communication portion, and controller that allows users to select and transmit only a part of the image to a display apparatus by dragging and dropping it into a drop area, enabling selective sharing and maintaining privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If screen mirroring is used to transmit the entire smartphone screen to a display apparatus, then the content can be displayed on a larger screen, but privacy issues arise and it is difficult to share only specific content
Solution Approach 1:
The patent divides the smartphone screen into selectable regions, allowing users to choose specific portions (e.g., photos, messages, videos) to share. The screen is segmented into shareable content areas and private areas, enabling selective display on the external device while maintaining privacy of unselected regions.
Solution Approach 2:
The patent extracts specific content elements (such as individual photos, messages, or video clips) from the complete smartphone screen and transmits only those extracted elements to the external display apparatus. This allows the desired content to be separated and shared independently from the rest of the screen information.
2Area of stationary object
If the entire smartphone screen is transmitted to the display apparatus, then content can be viewed on a larger screen, but it becomes difficult to use other smartphone functions simultaneously
Solution Approach 1:
The patent segments the smartphone display into multiple functional zones: a shareable content area that can be mirrored to the external device and a private control area that remains accessible on the smartphone. This allows users to interact with smartphone functions (checking calls, texts, notifications) in the private area while the shareable content is displayed on the larger external screen.
Solution Approach 2:
The patent introduces an intermediary interface layer that manages the separation between shared content and private controls. This intermediary system allows simultaneous operation of smartphone functions and external display without conflict, enabling users to check incoming calls or texts while content is being shared on the TV or external monitor.
3Object-affected harmful factors
If selective content sharing is implemented, then privacy is protected, but the system complexity increases compared to full screen mirroring
Solution Approach 1:
The patent implements self-service functionality where the smartphone automatically identifies and separates shareable content from private content based on user preferences or predefined rules. The system autonomously manages which content elements to transmit to the external device, reducing the need for complex manual configuration while maintaining privacy protection.
Solution Approach 2:
The patent creates a universal sharing framework that can handle multiple types of content (photos, messages, videos, notifications) through a single integrated system. This multi-functional approach allows the same selective sharing mechanism to work across different content types, simplifying the overall system architecture compared to implementing separate solutions for each content type.

AI summary
Apparatuses and methods related to a user terminal and a control method thereof are provided. More particularly, apparatuses and methods relate to a user terminal which enables a user to select a part of an image and to transmit the part of the image to a display apparatus. The user terminal includes a display unit configured to display an image and a drop area thereon, a communication portion configured to be connected to a display apparatus, and a controller configured to select at least a part of an image of the display unit by receiving a user's input, and if the selected part of the image is dragged and dropped into the drop area, controls the communication portion to transmit the selected part of the image to the display apparatus.
