Light Field Display Positioning Zone and Triggering Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When rendering Light Field content on a 2D display screen, users may experience limitations in scene coverage, leading to perceived holes or black surfaces on the edges due to their position, which affects the parallax rendering effect and Virtual Reality experience.
Innovation Solution
A method is implemented to generate a positioning zone and define a triggering area on the display screen, using pyramidal shapes centered on the user's head position, which triggers incentive effects such as darkening or parallax intensity adjustments to encourage the user to stay within the optimal viewing area, thereby enhancing the parallax effect and preventing edge limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Light Field content is rendered on a 2D display screen, then parallax capability and VR experience are provided, but scene coverage limitations occur leading to holes or black surfaces on the edges
Solution Approach 1:
The patent applies local quality by differentiating between a central positioning zone with full scene coverage and peripheral triggering areas with limited coverage. The system dynamically adjusts rendering quality and applies incentive effects specifically in the triggering areas where coverage limitations occur, rather than uniformly across the entire display.
Solution Approach 2:
The system dynamically adapts the rendering based on user head position within different zones. When the user moves into a triggering area, the system dynamically applies incentive effects such as darkening or parallax intensity adjustments to guide the user back to the optimal positioning zone, making the scene coverage adaptive rather than static.
2Area of stationary object
If incentive effects are applied to guide user position, then scene coverage is improved, but device complexity increases
Solution Approach 1:
The display area is segmented into distinct functional zones: a central positioning zone for optimal viewing and peripheral triggering areas for guidance. This segmentation allows the system to apply different rendering strategies and incentive effects to different regions, improving scene coverage without requiring complex global adjustments.
Solution Approach 2:
The patent introduces visual incentive effects as intermediaries between the user and the content. These effects (darkening, parallax intensity changes) act as mediators that indirectly guide user positioning without requiring direct control mechanisms, simplifying the overall system architecture.
3Area of stationary object
If darkening effect is applied to encourage user to stay in positioning zone, then scene coverage is maintained, but illumination intensity decreases
Solution Approach 1:
The darkening effect is applied locally only in the triggering areas where scene coverage limitations occur, rather than across the entire display. This allows the system to maintain full brightness in the central positioning zone while applying selective darkening in peripheral regions to guide user positioning.
Solution Approach 2:
The incentive effects are applied periodically or dynamically based on user position rather than continuously. When the user moves into a triggering area, the darkening effect is activated; when the user returns to the positioning zone, the effect is removed, creating a periodic pattern that guides positioning without sustained brightness reduction.
