Translucent Display Camera Alignment for Eye Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users in remote video communication systems cannot make direct eye contact due to the positioning of cameras, which affects the communication experience, and existing systems cannot display different views based on users' visual directions.
Innovation Solution
A video communication system with translucent displays and movable cameras that adjust to align with the position of users' eyes, allowing direct eye contact and immersive interaction by capturing and transmitting video information in real-time, using a micro processing unit to coordinate camera movements and display modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cameras are positioned fixedly to capture video, then video capture is simple and stable, but users cannot make direct eye contact and communication experience deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the camera position adjustable rather than fixed. The camera can be dynamically positioned at different locations (e.g., left eye position, right eye position, center position) according to the user's visual direction and interaction needs. This dynamic adjustment enables direct eye contact between users while maintaining operational simplicity through automated or semi-automated positioning systems.
2Device complexity
If a single fixed camera is used, then the system is simple and stable, but it cannot display different views according to users' visual directions
Solution Approach 1:
The system dynamically adjusts camera positioning based on user visual direction and interaction context. Instead of using a single fixed camera, the system can switch between multiple camera positions or adjust a single camera's position dynamically to capture different views (e.g., left eye view, right eye view, panoramic view), thereby enhancing adaptability without proportionally increasing system complexity.
Solution Approach 2:
The camera system is designed with multi-functionality to serve multiple purposes: capturing video for display, tracking user visual direction, and adjusting positions based on interaction needs. This universal design allows a single or small number of cameras to perform multiple functions including view switching, eye tracking, and immersive video capture, reducing overall system complexity while maintaining high adaptability.
3Reliability
If camera position is adjusted to align with user eyes, then direct eye contact is achieved and communication experience improves, but system complexity increases
Solution Approach 1:
The system employs self-service principles through automated camera positioning that responds to user visual direction and interaction context without requiring manual intervention. Eye tracking algorithms and computer vision techniques enable the system to automatically determine optimal camera positions and adjust them in real-time, reducing the need for complex manual control mechanisms while maintaining high communication quality.
Solution Approach 2:
The camera positioning system utilizes feedback from eye tracking, head pose estimation, and interaction context to continuously adjust camera positions. This closed-loop feedback mechanism ensures that cameras remain aligned with user eyes and visual direction, achieving direct eye contact while managing system complexity through intelligent automated control rather than rigid mechanical structures.
