Attention-Based Camera Selection for Inclusive Meeting Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing meeting room setups with wall-mounted cameras often leave remote attendees feeling excluded when conversation moves away from the main display, as existing solutions like 360° center-of-table cameras and PTZ systems fail to adequately address the shifting attention of in-room participants.
Innovation Solution
A system that uses computer vision and gaze detection to determine the attention direction of in-room participants, dynamically selecting the most appropriate local camera to capture images based on their focus, and transmitting these images to remote participants to maintain an inclusive meeting experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a wall-mounted camera is used in a meeting room, then the setup is simple and cost-effective, but remote attendees feel excluded when conversation moves away from the main display
Solution Approach 1:
The system divides the camera network into multiple spatially distributed cameras (front-of-room camera, side cameras, rear cameras) positioned at different locations around the meeting room. Each camera captures a specific zone, allowing the system to segment the viewing experience and select the appropriate camera based on where attention is directed, thereby resolving the contradiction between simple setup and adaptability to shifting focus
Solution Approach 2:
The system dynamically switches between different cameras based on real-time detection of attention direction. The camera selection is not fixed but adapts as conversation and attention move around the room. This dynamic switching mechanism allows the system to maintain simplicity in its physical setup while achieving high adaptability to shifting conversation focus through software-controlled camera selection
2Adaptability or versatility
If a 360° center-of-table camera is used to bring remote attendees' point of view to the table, then remote attendees feel more included, but the system cannot adequately capture shifting attention directions of in-room participants
Solution Approach 1:
The system introduces an attention detection module as an intermediary between the cameras and the remote attendees. This module processes visual data from multiple cameras to determine where in-room participants are looking and directs the appropriate camera feed to remote attendees. This intermediary layer enables precise measurement of attention direction while maintaining the inclusive feeling for remote participants
Solution Approach 2:
The system employs multiple cameras serving universal purposes - they not only capture images for remote attendees but also provide the data needed for attention direction detection. The same camera network serves dual functions: providing visual content and enabling attention analysis, thereby achieving both inclusion and precise attention capture without requiring separate specialized systems
3Adaptability or versatility
If PTZ systems are used to follow conversation focus, then the camera can track attention direction, but the system is complex and may not adequately capture the faces and front of participants when attention shifts
Solution Approach 1:
Instead of using a single complex PTZ system, the approach segments the coverage into multiple fixed cameras positioned at different locations (front, sides, rear). Each camera has a fixed field of view covering a specific zone. This segmentation simplifies each individual camera while collectively providing comprehensive coverage and the ability to track attention shifts by switching between segmented views
Solution Approach 2:
The system creates multiple copies of the meeting scene from different spatial perspectives through the distributed camera network. Rather than relying on a single camera that must physically rotate and zoom (PTZ), the system captures parallel views from multiple fixed positions and selects the appropriate copy based on attention direction. This copying approach reduces mechanical complexity while maintaining adaptability to tracking attention

Function Achieved in This Case
Enhances the sense of inclusion for remote attendees by providing a dynamic and intelligent representation of the meeting, ensuring they see the faces and front of in-room participants as their attention shifts, thereby improving the overall meeting experience.

AI summary
A computer implemented method includes detecting an attention direction of a local participant in an electronic meeting using an attention detector, selecting one of multiple local cameras to capture images of the local participant having a position most closely associated with the detected attention direction, and transmitting images from the selected one of the multiple cameras to remote participant devices. A gallery view may also be displayed on a display situated near the direction of attention.
