Portable Device Auto-Join for Video Conference Presence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video conferencing systems face challenges in identifying all conference participants in large rooms and effectively displaying both video feeds and shared materials, leading to difficulties in recognizing participants and viewing content, especially in large conference settings.
Innovation Solution
The technology automatically joins portable devices to a video conference without user intervention, using ultrasonic tokens or other methods to detect presence and pair devices, allowing for separate display of video on room displays and materials on portable devices, and includes user prompts for consent and configurable options to ensure user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If all conference participants are captured in one frame in a large conference room, then participant visibility is improved, but participant recognition becomes difficult
Solution Approach 1:
The system segments the conference room participants into multiple groups or regions, with each portable device capturing a specific segment. This allows participants to be viewed in closer detail rather than all compressed into one frame, resolving the contradiction between coverage area and recognition precision.
Solution Approach 2:
Portable devices act as intermediaries between the conference room display system and individual participants. Each portable device captures and transmits specific participant views to remote endpoints, enabling clear identification without requiring all participants to fit in a single large-room frame.
2Quantity of substance
If conference room display presents both video of speaker and shared conference materials simultaneously, then information completeness is improved, but content readability deteriorates
Solution Approach 1:
The display content is segmented into separate channels: the conference room display shows video feeds while portable devices receive and display shared conference materials. This segmentation allows both video and materials to be presented simultaneously without competing for the same display space, maintaining both information completeness and readability.
Solution Approach 2:
The system transitions from a two-dimensional display conflict (video vs. materials on the same screen) to a multi-dimensional distribution model where different content types are delivered to different devices. Video remains on the conference room display while materials are distributed to portable devices, eliminating the readability problem.
3Adaptability or versatility
If portable devices are manually joined to video conference, then device integration is achieved, but user operation complexity increases
Solution Approach 1:
The portable devices automatically join the video conference without requiring manual user intervention. The system detects portable devices in the conference room and automatically integrates them into the conference, eliminating the need for users to perform complex pairing or joining operations while achieving full device integration.
Solution Approach 2:
The system performs preliminary actions by pre-configuring portable devices with conference joining capabilities before the conference begins. Devices are automatically recognized and integrated at the start of the conference, eliminating the need for users to perform manual setup actions during the event.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances participant identification and content visibility by automatically adding all participants to a roster and directing video and materials appropriately, improving the conference experience by ensuring all participants can see each other and shared content without user action.

AI summary
The present technology allow for a user's portable device to automatically join a videoconference without any action by a user. A collaboration service can be aware of portable devices in a conference room that is an endpoint for a video conference, and learn of identities associated with the portable devices present in the conference room. After the video conference is initiated in the conference room, all devices that are in communication with the collaboration service can also be automatically joined to the conference. Since all conference participants in the conference room have their own portable device that is joined to the conference the portable devices in the conference room act as a second screen available to the video conference. As such video from the conference can be directed to a common conference room display, while conference materials can be displayed separately on the portable devices. Additionally, each conference participant's identity can be added to a conference participant roster automatically.
