Multi-layer Display Head Tracking Depth Fusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-layer display systems face challenges in maintaining visual depth information and clarity when viewed from angles other than the normal position, due to issues with content alignment and parallax, leading to 'sweet spots' where the image breaks or becomes distorted.
Innovation Solution
The implementation of head and eye tracking technology to algorithmically adjust and skew content on multiple display layers, ensuring it is rendered from the viewer's perspective and appears to exist between layers, using projection matrices and depth maps to maintain clarity across varying angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content is displayed on multiple display layers without adjustment, then the display structure is simple, but the content alignment breaks and visual depth information is lost when viewed from angles other than normal
Solution Approach 1:
The patent applies dynamics by making the content display adaptive to the viewer's head position. The system dynamically adjusts content skew and position based on real-time head tracking data, transforming static content into dynamically adjusted content that maintains proper alignment across multiple display layers regardless of viewing angle
Solution Approach 2:
The patent changes display parameters (skew angle, position offset) based on head position parameters. By calculating the relationship between head position and required content adjustment, the system modifies display parameters to compensate for parallax effects, ensuring content remains aligned across layers
2Reliability
If head tracking and algorithmic content adjustment is implemented, then content alignment and depth perception are maintained across varying angles, but the device complexity increases
Solution Approach 1:
The patent implements feedback through head tracking that continuously monitors viewer position and feeds this information back to the content rendering system. This closed-loop feedback mechanism allows the system to automatically adjust content skew and position based on actual viewing conditions, maintaining depth perception reliability
Solution Approach 2:
The patent introduces head tracking technology as an intermediary between the viewer and the display system. This intermediary captures head position data and enables the processing system to calculate appropriate content adjustments, serving as a bridge that connects viewer behavior to display rendering
3Ease of operation
If content is rendered from viewer's perspective with skew adjustment, then viewability is improved, but the processing complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-calculating skew and position adjustments based on head position. Rather than adjusting content in real-time during rendering, the system determines the required transformations in advance based on tracked head position, improving viewability while managing processing complexity

AI summary
A multi-layer display (MLD) system may include a plurality of display screens including at least first and second display screens arranged in a substantially parallel and overlapping manner, and a processing system comprising at least one processor and memory. The processing system may be configured to render content on and between two MLD layers, such that the content is correctly rendered from the perspective angle of the viewer.
