Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional display systems present content without dynamic adaptation, then device complexity is reduced, but visual comfort deteriorates
Solution Approach 1:
The patent segments the display content into foveal and peripheral regions, applying different processing strategies to each. The foveal region receives high-quality rendering while the peripheral region uses simplified processing, thereby reducing overall system complexity while maintaining visual comfort in critical areas.
Solution Approach 2:
The patent implements local quality by applying different modification methods to different regions of the display. The foveal region undergoes minimal modification to preserve visual acuity, while the peripheral region receives more aggressive modifications to reduce eye strain, optimizing visual comfort without uniformly increasing system complexity.
2Object-affected harmful factors
If display systems apply sophisticated content modification, then visual comfort is improved, but processing time increases
Solution Approach 1:
By segmenting the display buffer into foveal and peripheral regions, the system applies sophisticated modifications only where necessary (peripheral region) while using simpler processing for the foveal region, thereby reducing overall processing time while still addressing eye strain in the peripheral visual field.
Solution Approach 2:
The patent applies partial action by modifying only the peripheral region content rather than the entire display buffer. This selective approach reduces processing time while still providing sufficient modification to alleviate eye strain in the peripheral visual field where excessive detail is less critical.
3Adaptability or versatility
If display systems use static characteristics, then device complexity is reduced, but adaptability to user needs deteriorates
Solution Approach 1:
The patent implements dynamics by dynamically adjusting the display buffer content based on real-time gaze estimation and content analysis. The system adapts to individual user needs by modifying peripheral region content according to current viewing conditions and user characteristics, achieving high adaptability without requiring complete system redesign.
Solution Approach 2:
The patent introduces an intermediary processing layer (the content regulator module) that sits between the original display buffer and the final output. This intermediary dynamically adjusts content based on gaze direction and user needs, providing adaptability while keeping the core display system architecture relatively simple.
