Multi-Participant Display Sharing With Primary Presenter Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conferencing software allows only a single participant to share content at a time, leading to interruptions and disruptions when multiple participants want to share, disrupting the flow of information and causing frustration among viewing participants.
Innovation Solution
Enabling multiple participants to simultaneously share content in a conference, with seamless switching between primary and secondary presenters, allowing viewing participants to easily select and view shared displays independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If only a single participant is allowed to share content at a time, then the system complexity is reduced and easier to manage, but the productivity and continuity of information sharing is disrupted due to interruptions
Solution Approach 1:
The patent segments the content sharing functionality by allowing multiple participants to simultaneously share different content streams (first content from first presenting device, second content from second presenting device). Each participant can share independently without blocking others, dividing the sharing process into parallel independent streams rather than a single sequential channel.
Solution Approach 2:
The patent introduces a new dimension to content sharing by enabling multiple content streams to coexist in the same viewing space. Instead of a single linear sharing sequence, the system creates a multi-dimensional sharing environment where different participants can present simultaneously at different 'levels' or layers, accessible through the gallery view interface.
2Productivity
If multiple participants share content simultaneously, then the productivity and engagement are improved, but the ease of operation and user interface complexity increases
Solution Approach 1:
The patent segments the viewing interface into distinct components: a gallery view showing multiple content streams simultaneously, and an overlay view for detailed interaction with selected content. This segmentation allows users to easily navigate multiple sharing streams without confusion, as each stream is visually distinct and can be independently selected for detailed viewing.
Solution Approach 2:
The patent introduces an intermediary interface layer (the gallery view with content stream representations) that mediates between the multiple simultaneous sharing streams and the user's viewing needs. This intermediary structure organizes the complexity by presenting simplified thumbnails or representations of each stream, allowing users to easily select desired content without being overwhelmed by the underlying complexity of multiple simultaneous shares.
3Loss of time
If sequential sharing is used, then the device complexity is minimized, but the loss of time occurs when participants must wait for turns
Solution Approach 1:
The patent ensures continuity of useful action by allowing multiple participants to share content simultaneously without interruption. While one participant shares their content stream, other participants can concurrently share their own content streams, eliminating the waiting periods inherent in sequential sharing. The system maintains continuous productive activity across all sharing streams rather than forcing sequential turns.
Solution Approach 2:
The patent enables preliminary action by allowing participants to prepare and have their content streams ready before needing to share. Multiple participants can simultaneously prepare their content and have it queued or pre-loaded in the system, so when they need to share, their content is already prepared and can be immediately displayed without waiting for others to finish or for system preparation.
Data Source
AI summary
A conferencing server receives content streams from presenting devices connected to a conference. Each content stream is received from a respective one of the presenting devices. The conferencing server transmits the content streams to a viewing device connected to the conference. The conferencing server receives a request to designate one of the presenting devices as a primary presenting device. The conferencing server then transmits an indication of the primary presenting device to the viewing device.
