Multi-Display Capture System for Emergency Application Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen-sharing tools are inadequate for sharing multi-screen or multi-window applications, such as 9-1-1 call handling and dispatching software, as they cannot effectively display and manage multiple simultaneous screens or windows, leading to cumbersome user experiences for both sharers and viewers.
Innovation Solution
A multi-display capture system that allows users to select and capture multiple display areas, generating a combined display that can be shared, with options to label, arrange, and enlarge specific areas, ensuring real-time updates and full context visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing screen-sharing tools are used to share multi-screen applications, then single screen or window sharing is supported, but multiple simultaneous screens or windows cannot be effectively displayed
Solution Approach 1:
The system segments the multi-screen display into multiple individual screen captures, allowing each screen to be selected and shared independently. The user can choose to share one or more specific screens from the multi-screen setup, transforming the complex multi-screen sharing problem into manageable individual screen shares.
Solution Approach 2:
The system adds a temporal dimension to screen sharing by enabling seamless switching between different screen captures during the sharing session. This allows the shared content to transition between multiple screens over time, effectively sharing the entire multi-screen workspace rather than being limited to a single static screen.
2Loss of information
If multiple display areas are captured simultaneously, then full context visibility is achieved, but display complexity and management difficulty increase
Solution Approach 1:
The system implements dynamic display management where the arrangement and visibility of multiple screen captures can be adjusted in real-time. Users can switch between different screen captures, enlarge specific areas, and control which screens are visible at any given moment, making the complex multi-screen display adaptive and easy to manage.
Solution Approach 2:
The system nests multiple screen captures within a unified display interface, allowing each individual screen to be contained within the overall multi-screen shareable display. This hierarchical structure enables users to view multiple screens simultaneously while maintaining the ability to focus on individual screens when needed.
3Loss of information
If screen sharing is enabled for multi-screen applications, then complete application context can be shared, but user experience becomes cumbersome for both sharers and viewers
Solution Approach 1:
The system performs preliminary organization of multiple screen captures before the sharing session begins. Screens are pre-configured and made available for selection, allowing users to quickly start sharing without having to manually arrange or configure each screen during the session, thus improving ease of operation.
Solution Approach 2:
The system introduces an intermediary interface that manages the complexity of multi-screen sharing between the application and the users. This intermediary layer handles screen selection, arrangement, and switching automatically, shielding users from the underlying complexity while preserving complete application context visibility.

AI summary
A multi-display capture system receives user selections of two or more display areas, such as screens or application windows, generated by a computing device. The multi-display capture system simultaneously captures a video stream of each of the selected display areas. In another display area, the multi-display capture system outputs a combined display that includes each of the captured video streams. The user may select a video stream to enlarge, and the multi-display capture system enlarges the video streams while continuing to display the other video streams. The combined display may be shared with one or more other users.
