Stereoscopic Display Using Translucent Reflection for Multi-Angle Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stereoscopic image display technologies fail to provide a realistic three-dimensional effect and spatial sensation, especially in allowing users to view images from various angles and directions, as they are limited by the binocular disparity principle and do not effectively utilize gaze tracking for personalized image rendering.
Innovation Solution
An apparatus and method that utilize a translucent reflective structure, combined with a main display and sub-display, to split and reflect stereoscopic images based on user gaze and viewpoint information, allowing for a more immersive and realistic three-dimensional experience by generating and displaying stereoscopic images on a table surface and in space, accommodating multiple users with varying viewpoints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If binocular disparity principle is used to display stereoscopic images, then three-dimensional effect is generated, but realistic spatial sensation and multi-angle viewing experience are limited
Solution Approach 1:
The display system is segmented into multiple independent display parts (main display part and sub-display part) that can present different stereoscopic images simultaneously. Each display part targets specific viewing zones, allowing multiple users to view from different angles without compromising the three-dimensional effect for any individual viewer.
Solution Approach 2:
The invention transitions from traditional single-plane 2D/3D display to a multi-dimensional spatial display system using translucent reflective structures. Images are projected onto both the main display surface and reflected through translucent portions to create virtual images in three-dimensional space, enabling viewing from multiple angles while maintaining spatial accuracy.
2Adaptability or versatility
If single display surface is used for stereoscopic images, then device complexity is reduced, but viewing directions and spatial immersion are limited
Solution Approach 1:
The main display part serves multiple functions simultaneously: it displays direct stereoscopic images for front viewers, reflects images through its translucent portion for top viewers, and works in conjunction with the sub-display part to create comprehensive multi-angle coverage. This multi-functionality increases viewing direction coverage without proportionally increasing overall system complexity.
Solution Approach 2:
The translucent reflective structure acts as an intermediary between the sub-display part and the viewer. It receives light from the sub-display, reflects it to create virtual images in space, and allows simultaneous viewing of both the main display and reflected images, thereby expanding viewing directions without requiring separate independent display systems.
3Measurement precision
If gaze tracking is not implemented, then device complexity is lower, but stereoscopic image accuracy matching user gaze is reduced
Solution Approach 1:
The user tracking part continuously monitors viewer position and gaze direction, providing real-time feedback to the stereoscopic image generating part. This feedback loop enables dynamic adjustment of the stereoscopic images presented to each viewer, ensuring that the three-dimensional effect and spatial accuracy are precisely matched to each user's actual gaze direction and viewing angle.

AI summary
Disclosed is an apparatus for displaying stereoscopic images. The apparatus for displaying stereoscopic images includes a stereoscopic image-generating part, a main display part, a sub-display part, and a translucent reflective structure part. The stereoscopic image-generating part splits a single image to generate a first stereoscopic image to be directly viewed by a user and a second stereoscopic image to be reflected and viewed by the user. The main display part directly displays the first stereoscopic image to a gaze of a user. The sub-display part displays the second stereoscopic image. The translucent reflective structure part reflects the second stereoscopic image displayed on the sub-display part.
