Movable Camera Aligns With Eye Position on Translucent Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of remote video communication systems cannot make direct eye contact due to the misalignment of camera views, and existing systems cannot display different visual directions, leading to a suboptimal communication experience.
Innovation Solution
A video communication system with translucent displays and movable cameras that adjust to align with the user's eye position, 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 a traditional video communication system uses a fixed camera and display arrangement, then the system structure is simple, but users cannot make direct eye contact because the eyes displayed on the display are spaced apart from the camera
Solution Approach 1:
The camera is made movable instead of fixed, allowing it to adjust its position and angle dynamically. The camera can move horizontally and vertically to align with the user's eye position, enabling direct eye contact during video communication. This dynamic adjustment resolves the contradiction by sacrificing fixed structure simplicity for the benefit of eye contact capability.
2Adaptability or versatility
If a video player displays only a fixed video view, then the display function is simple, but it cannot display different videos or views according to users' different visual directions
Solution Approach 1:
The system uses sensors to detect the user's visual direction and provides feedback to the display module. Based on this feedback, the display dynamically adjusts to show different video views corresponding to the user's visual direction. This feedback mechanism enables the display to adapt to different visual directions while maintaining a relatively simple display structure.
3Measurement precision
If the camera is positioned to capture a wide field of view, then the coverage area is large, but the precision of eye contact alignment is reduced
Solution Approach 1:
The camera dynamically adjusts its field of view based on the detected eye position. When eye contact is detected, the camera can narrow its focus to achieve precise alignment. This dynamic adjustment allows the system to switch between wide coverage and precise alignment as needed, resolving the contradiction between field of view and alignment precision.
