Camera-Aligned Display Layout for Speaker Visibility in Video Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems fail to consider the layout of projection images relative to a camera's position, leading to reduced visibility and discomfort due to overlapping camera regions, especially during video conferences.
Innovation Solution
A display method and system that adjusts the positioning and sizing of images on a display surface based on the camera's location, prioritizing the camera-aligned position for the speaker's image and enlarging it during their utterance, while ensuring non-overlapping and maintaining visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera is arranged to overlap the screen to capture the speaker, then the camera can image the user effectively, but the visibility of the overlapping portion deteriorates
Solution Approach 1:
The projection image layout is dynamically adjusted based on who is speaking. When the first user speaks, their image is positioned at the camera location; when the second user speaks, the layout switches to prioritize their image. This dynamic repositioning resolves the contradiction by making the camera overlap beneficial for the active speaker while avoiding visibility issues for others.
Solution Approach 2:
Different regions of the projection image are assigned different functions based on their position. The center region (camera location) is specifically designated for displaying the speaker's image, while other regions display listener images. This local differentiation allows the camera overlap zone to serve a specific purpose without compromising overall visibility.
2Object-affected harmful factors
If the projection image layout is fixed to avoid the camera, then the camera region visibility is maintained, but the layout does not adapt to image content requirements
Solution Approach 1:
The system transitions from a static layout to a dynamic one that automatically reconfigures based on the active speaker. The projection image positions are adjusted in real-time according to speech detection, enabling the layout to adapt to different conversation scenarios while maintaining visibility by strategically placing images.
Solution Approach 2:
The system uses speech detection feedback to determine which user is speaking and automatically adjusts the projection image layout accordingly. This feedback mechanism enables the system to adapt the layout to the current conversation state, resolving the contradiction between fixed visibility and adaptive content requirements.
3Ease of operation
If the speaker's image is positioned at the camera location, then user engagement is enhanced through gaze direction, but the image may overlap with the camera and reduce visibility
Solution Approach 1:
The system creates a specialized display zone at the camera location specifically for the speaker's image. This local assignment ensures that the speaker's image is always positioned to maximize engagement (at the natural gaze point) while the system manages the overlap by ensuring no other images conflict with this primary display zone.

AI summary
A display method including obtaining information representing position on display surface of camera which is arranged on display surface to image first user, displaying first image related to an utterance by first user, and a second image which represents second user, the second image being arranged at position closer to position of the camera than a position of the first image is to the position of the camera, on the display surface during a period in which the second user makes an utterance, transmitting an image obtained by the camera during the period in which the second user makes the utterance, to a terminal device used by the second user, and displaying, on the display surface during a period in which the first user makes an utterance, the first image larger than the first image during the period in which the second user makes the utterance and the second image.
