Solution Overview
Problem
Current devices fail to effectively replicate the experience of face-to-face interaction in remote scenarios, lacking the ability to capture and display eye-related information and gaze direction accurately to create a window-like effect for real-time communication.
Innovation Solution
A system comprising a steerable array of beam-deflecting facets combined with a large area camera and a window-simulation controller, which captures and processes eye-related information to simulate the view of a remote user, allowing for real-time image presentation and capture, mimicking a window-like experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional display device is used for video conferencing, then the basic display function is provided, but the ability to accurately capture and display eye-related information and gaze direction is lost
Solution Approach 1:
The display device is segmented into multiple functional layers: a display panel for image output, a camera array for capturing eye-related information, and a beam-deflecting facet array for directing light. Each component performs a specific function, allowing the system to accurately capture gaze direction while maintaining a relatively simple overall structure.
Solution Approach 2:
The camera array and beam-deflecting facet array are integrated behind the display panel, creating a nested structure where multiple functional elements are contained within the display device housing. This nesting approach enables complex functionality without significantly increasing the external dimensions or visual complexity of the device.
2Adaptability or versatility
If a window-like effect is implemented for real-time communication, then the face-to-face interaction experience is improved, but the device complexity increases due to multiple integrated components
Solution Approach 1:
The display device is designed to perform multiple functions: displaying video images, capturing eye-related information through the camera array, and directing light through beam-deflecting facets. This multi-functionality enables the device to create a window-like effect for real-time communication while consolidating multiple capabilities into a single integrated system.
Solution Approach 2:
The display panel, camera array, and beam-deflecting facet array are merged into a single integrated device. The camera array and beam-deflecting facets are positioned behind the display panel, combining capture and display functions in one unit, thereby enabling real-time communication with a window-like effect without requiring separate devices.
3Measurement precision
If beam-deflecting facets are used to direct light for accurate gaze capture, then the measurement precision of eye information is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The beam-deflecting facet array replaces complex mechanical eye-tracking systems with an optical approach. By using fixed geometric facets that passively direct light based on incident angle, the system achieves accurate gaze detection without requiring moving parts or complex mechanical adjustment mechanisms, thereby simplifying manufacturing.
