Interest-Aware Disparity Mapping for 3D Gaming Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D gaming technologies face challenges in providing a comfortable viewing experience across different devices with varying screen sizes, leading to eyestrain and discomfort due to inconsistent depth perception, as they typically use constant disparity values adjusted for dedicated devices without considering the unique screen sizes and viewing distances of other devices.
Innovation Solution
Implementing interest-aware disparity mapping algorithms that adjust 3D content in real-time to ensure all objects fall within a comfortable viewing range on different devices, preserving the depth information of important objects and minimizing distortion, by analyzing screen size and expected viewer distance for each device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If constant disparity values adjusted for dedicated devices are used, then depth perception is optimized for specific devices, but viewing comfort deteriorates across devices with different screen sizes
Solution Approach 1:
The system dynamically adjusts disparity values based on the target device's screen size and viewing distance characteristics. Instead of using fixed constant disparity values optimized for dedicated devices, the disparity mapping parameters are adapted in real-time to match the specific display characteristics of tablets, smartphones, or other devices, thereby maintaining both depth perception accuracy and viewing comfort across diverse platforms
Solution Approach 2:
The invention changes the disparity mapping parameters according to the target device's screen dimensions and expected viewing distance. By modifying these critical parameters based on device-specific characteristics, the system achieves optimal depth perception and viewing comfort for each device type while maintaining a single code base
2Ease of operation
If disparity mapping is optimized for dedicated devices, then viewing comfort is improved for those devices, but depth information of important objects is lost when displayed on other devices
Solution Approach 1:
The system applies different disparity mapping strategies to different regions or objects within the 3D scene based on their importance. Important objects retain their original depth information and disparity characteristics, while less critical elements are adjusted to fit the comfortable viewing range. This localized approach ensures that depth information of key objects is preserved while maintaining overall viewing comfort on various devices
3Device complexity
If a single code base is used across multiple devices, then development complexity is reduced, but viewing distortion increases due to different screen sizes
Solution Approach 1:
The invention implements a universal disparity mapping framework that functions across all device types through a single code base. The system includes device configuration detection and adaptive parameter adjustment capabilities that work universally for tablets, smartphones, and other displays, eliminating the need for separate code versions while maintaining consistent viewing quality through automated adaptation to different screen characteristics
