Transparent Display Eye Contact Alignment Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In online meetings, users often fail to maintain eye contact due to misalignment between the camera position and the displayed user's position on transparent display devices, leading to a deterioration in communication quality.
Innovation Solution
The electronic apparatus includes a controller that compares the position of the camera with the displayed user's image and adjusts the display to ensure the camera is superimposed over the user's eyes, allowing for eye contact by synchronizing the camera and display panel drives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera is positioned opposite the transparent display to capture user images, then the camera can record the user's face and expressions, but the camera position does not align with the displayed user's position on the display panel, causing misalignment and preventing eye contact
Solution Approach 1:
The patent creates a virtual copy of the camera's viewing angle by calculating and displaying the user's image at a position that corresponds to the camera's optical axis. The controller generates display information that positions the user's eyes at the same angular position as the camera, creating a virtual alignment that enables eye contact even though the physical camera position remains fixed opposite the display.
Solution Approach 2:
The patent changes the display parameters by calculating adjusted position coordinates for the user's image based on the camera's position and the user's actual position. The controller modifies the display information to shift the user's image position on the display panel, transforming the fixed camera-position relationship into a dynamic position adjustment that enables eye contact.
2Adaptability or versatility
If the user's image is displayed at the actual camera position on the display panel, then the camera position is fixed, but when the user moves or changes posture, the displayed position does not match the user's new position, deteriorating communication quality
Solution Approach 1:
The patent implements a feedback mechanism where the sensor continuously detects the user's position and posture, and the controller uses this information to dynamically adjust the display position. The system forms a closed-loop control where the user's movement is detected and immediately reflected in the display position adjustment, enabling real-time adaptation to maintain eye contact.
Solution Approach 2:
The patent transforms the static display position into a dynamic one by continuously updating the user's image position based on real-time sensor data. The display position is no longer fixed but adapts dynamically to the user's movements and posture changes, enabling the system to maintain eye contact alignment regardless of user position variations.
3Adaptability or versatility
If the sensor detects user position and the system adjusts display based on detected position, then the system can adapt to user movement, but the detection and adjustment process adds system complexity
Solution Approach 1:
The patent makes the existing sensor and controller serve multiple functions: the sensor not only detects user position for display adjustment but also provides information for eye contact alignment calculation. The controller performs both general display control and specific eye contact position adjustment using the same hardware components, reducing the need for additional dedicated components and minimizing system complexity increase.

AI summary
According to one embodiment, an electronic apparatus includes a display panel including a display area, a camera opposed to the display area of the display panel, and a controller that controls drive of the display panel and drive of the camera, the controller compares a position of an image of an eye of a user displayed in the display area and a position of the camera, and moves, in a case where difference is present between the position of the image of the eye of the user and the position of the camera, an image of the user such that the position of the image of the eye of the user is superposed on the position of the camera.
