Screen Sharing Control Authority and Display Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen sharing technologies do not allow users to easily change control authority among devices or provide additional information on shared content, limiting flexibility and interaction in collaborative environments.
Innovation Solution
A method and device that allow users to set control authority of a screen sharing service based on user input, enabling a user device to take control and transmit control commands, while also displaying additional information by splitting the screen to show shared content and extra details.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control authority is centralized in a particular device or server, then system stability is improved, but flexibility to change control authority and provide additional information deteriorates
Solution Approach 1:
The patent implements dynamic control authority assignment where any device in the screen sharing system can be designated as the control device through user input. The control rights are not fixed but can be transferred dynamically, allowing the system to adapt control flexibility while maintaining stability through structured authority management protocols.
Solution Approach 2:
The patent introduces a control device as an intermediary between the screen sharing system and additional information sources. This intermediary manages control authority and coordinates information distribution, enabling flexible assignment of control while maintaining system stability through centralized coordination.
2Adaptability or versatility
If control authority is distributed among multiple devices, then flexibility is improved, but system complexity and coordination difficulty increase
Solution Approach 1:
The patent segments control authority into distinct functions: the control device manages authority assignment and coordinates information flow, while other devices focus on displaying shared content and receiving additional information. This segmentation reduces coordination complexity by clearly defining roles while maintaining flexibility in authority assignment.
Solution Approach 2:
The control device serves as an intermediary that simplifies coordination by centralizing authority management. Instead of requiring complex peer-to-peer coordination among all devices, the control device mediates information flow and control transitions, reducing overall system complexity while preserving flexibility.
3Ease of operation
If additional information is displayed on shared content, then user experience is improved, but screen space for shared content is reduced
Solution Approach 1:
The patent segments the display area into multiple regions: one region displays the shared content while another region displays additional information. This spatial segmentation allows both the shared content and supplementary information to be visible simultaneously, enhancing user experience without completely sacrificing screen space for either purpose.
Solution Approach 2:
The patent utilizes the spatial dimension of the display by arranging content and additional information in different areas of the screen. This dimensional arrangement allows users to access both shared content and additional information within the same display space, improving user experience while maintaining adequate screen real estate for primary content.

AI summary
A method for sharing content with an external device (110). The method comprising displaying (S210) content on a display of a user device (100) and sharing the displayed content with an external device (110) by using a screen sharing service. The method further comprises setting (S360) the user device (100) to have control authority of the screen sharing service based on a user input. The method further comprises transmitting (S220) control authority setup information indicating that the user device (100) has the control authority of the screen sharing service, to the external device (110). The method further comprises transmitting (S230) a control command to the external device (110) for controlling the shared content at the external device (110) according to the control authority of the screen sharing service. The method is characterized in that the control authority includes authority for displaying additional information regarding the displayed content, and the method further comprises displaying (S370) the additional information on the display of the user device (100) according to the authority for displaying the additional information.
