Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional virtual 3D game rendering is used, then the game can be displayed on standard screens, but the visual effects lack vividness and immersion
Solution Approach 1:
The patent transitions from conventional 2D/flat 3D rendering to true stereoscopic 3D by introducing depth dimension calculation. It computes depth information for each pixel based on view matrix transformation and projection matrix, enabling the display of objects with realistic depth perception rather than just flat images or simple pseudo-3D effects.
Solution Approach 2:
The patent dynamically adjusts stereoscopic display parameters including viewing distance, viewing angle, and depth scale factor based on eye position parameters detected by the eye tracker. This allows the 3D effect strength and depth perception to be optimized in real-time according to the viewer's actual position and orientation, enhancing visual vividness and immersion.
2Reliability
If eye tracking and real-time parameter adjustment are implemented, then visual immersion is enhanced, but system complexity increases
Solution Approach 1:
The patent integrates multiple functions into a unified rendering pipeline: eye position acquisition, head pose estimation, view matrix transformation, projection matrix calculation, and stereoscopic image generation all occur within the existing game rendering system. This multi-functional integration minimizes additional hardware requirements while achieving enhanced immersion.
Solution Approach 2:
The patent replaces complex mechanical eye tracking hardware with software-based eye position estimation using facial feature point detection from camera images. This substitution reduces mechanical complexity while maintaining the ability to track eye position and adjust stereoscopic parameters in real-time.
3Reliability
If stereoscopic 3D conversion is applied to all games, then immersive experience improves, but processing time and computational resources increase
Solution Approach 1:
The patent performs view matrix and projection matrix calculations based on predicted future eye positions using gyroscope data and AI models. By anticipating the viewer's next gaze direction and position, the system pre-calculates rendering parameters, reducing real-time processing delays and maintaining smooth frame rates during stereoscopic conversion.
Solution Approach 2:
The patent implements dynamic adjustment of stereoscopic rendering intensity and depth scale factor based on game scene characteristics and eye movement patterns. For static scenes or less critical moments, rendering complexity is reduced, while dynamic action sequences receive full stereoscopic processing, optimizing the balance between immersion and processing time.
