Video Conference Participant Layout by Camera State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video conference systems display all participants' images in the same size and fixed positions, making it difficult for users to intuitively distinguish between active and inactive participants, thereby reducing communication efficiency and user experience.
Innovation Solution
The method involves displaying media streams from terminals with ON cameras in a predetermined size in a first area and those with OFF cameras in a reduced size in a second area, with separate zones for recording and non-recording zones, and adjusting display based on participant identity and number of presenters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all participants' images are displayed in the same size and fixed position, then the display layout is simple and uniform, but participants with cameras OFF occupy excessive display area and reduce visibility of active participants
Solution Approach 1:
The patent applies local quality by differentiating the display characteristics based on camera state. Participants with cameras ON are displayed in a first area with larger size and different visual characteristics, while participants with cameras OFF are displayed in a second area with reduced size. This creates localized display qualities that match the functional state of each participant, allowing active participants to be prominently visible while minimizing the space occupied by inactive participants.
2Device complexity
If all participants' images are displayed in the same size, then the display is uniform and easy to implement, but it is difficult to intuitively distinguish between active and inactive participants
Solution Approach 1:
The patent employs visual differentiation through color and brightness changes to indicate participant status. Participants with cameras ON are displayed with higher brightness and distinct visual characteristics in the first area, while participants with cameras OFF are displayed with reduced brightness and different visual characteristics in the second area. This use of visual properties allows intuitive distinction of participant status without requiring complex additional indicators.
Solution Approach 2:
The patent introduces a spatial dimension by dividing the display into a first area for active participants and a second area for inactive participants. This spatial separation, combined with size differentiation, creates a hierarchical display structure that naturally conveys participant status. The dimensionality change from uniform display to differentiated spatial zones enables intuitive information transmission about who is actively participating.
3Stability of the object's composition
If participants with cameras OFF are displayed in the same size as active participants, then the display layout is consistent, but other participants cannot intuitively perceive the information of different participants
Solution Approach 1:
The patent implements dynamic display characteristics that adapt to the camera state of each participant. The display system automatically adjusts the size, area, and visual properties of participant images based on whether their camera is ON or OFF. This dynamic adaptation maintains layout consistency through systematic rules while simultaneously conveying activity status through differentiated visual characteristics, resolving the contradiction between consistency and information transmission.

AI summary
The method comprises: Step S1: receiving a media stream pushed by a terminal and determining the camera state of the terminal, if the camera of the terminal is ON, then proceeding to Step S2; if the camera of the terminal is OFF, then proceeding to Step S3; Step S2: displaying the media stream of the terminal in a predetermined size in a first predetermined area; and Step S3: displaying the media stream of the terminal in a reduced size in a second predetermined area. Disclosed in embodiments of the present application is a method for presenting information of video conference participants, which enables a participant to intuitively learn information about other participants, by showing their information in the first area or the second area presented locally based on the camera state of their respective terminals, thus greatly improving the conference communication efficiency and the user experience.
