Display System Gaze Alignment via Dynamic Image Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In distant communication setups, misalignment between the camera position and the displayed image can cause an uncomfortable feeling due to perceived mismatched gaze direction, leading to discomfort for users.
Innovation Solution
A display method and system that adjusts the positioning of images on a display surface relative to the camera's position, ensuring the image of the user making a sound is displayed closer to the camera during speech, and transmitting the camera's image to the user's terminal device, thereby aligning the perceived gaze direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera is arranged on the display surface to take an image of the user, then a feeling of presence as if the own space and the other space were connected is achieved, but misalignment between the camera position and the displayed image position causes gaze misalignment and uncomfortable feeling
Solution Approach 1:
The patent applies local quality by making different parts of the display system have different functions: the camera is positioned at a specific location on the display surface to capture images, while the displayed image of the remote user is dynamically positioned to align with the camera location. This spatial coordination ensures that when the remote user looks at their captured image, their gaze naturally aligns with the local user's face, creating comfortable eye contact without requiring the entire system to be symmetric or uniformly arranged.
Solution Approach 2:
The system uses feedback by continuously monitoring the camera position on the display surface and adjusting the displayed image position accordingly. The image processing device determines the camera's location and dynamically positions the remote user's image to align with that location, creating a closed-loop system that maintains gaze alignment. This feedback mechanism ensures that any changes in camera positioning are compensated by corresponding adjustments in image placement.
2Device complexity
If the camera position is fixed on the display surface, then the display system is simple to implement, but the image position cannot be adjusted to match different camera arrangements
Solution Approach 1:
The patent applies dynamics by making the image position adjustable and adaptive rather than fixed. The image processing device dynamically determines the camera's position on the display surface and automatically adjusts the displayed image position to align with the camera. This dynamic positioning capability allows the system to adapt to different camera arrangements and display configurations without requiring complex manual reconfiguration, maintaining simplicity while enhancing versatility.
Solution Approach 2:
The system utilizes parameter changes by modifying the image position parameter based on the camera's detected location. When the camera position changes or is initially determined, the system changes the display coordinates of the remote user's image to match the camera's position. This parameter adjustment mechanism enables the system to accommodate various camera arrangements and display setups while maintaining proper gaze alignment.

AI summary
A display method includes displaying a first image representing a first user and a second image representing a second user on a display surface on which a camera is arranged, obtaining information representing a position of the camera on the display surface, outputting a sound made by the first user, displaying the first image at a position, the position being closer to a position of the camera than a position at which the second image is displayed is, during a period in which the sound made by the first user is output, and transmitting an image obtained by the camera during the period in which the sound made by the first user is output, to a terminal device used by the first user.
