Multi-View Display Spatial Zone Content Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional signs and displays often fail to provide relevant and intelligible content to viewers due to limitations in viewing distance, angle, and context, leading to cluttered, obstructed, or distorted views, and existing solutions like multiple displays or content cycling can be cumbersome and inefficient.
Innovation Solution
A multi-view display system that uses multi-view pixels to emit beamlets of light, which can be controlled independently in brightness and direction, allowing different content to be displayed to different viewers in spatially distinct zones based on their location and context, with a sensing system to account for obstructions and viewing angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple displays are installed to provide location-relevant information to different viewers, then the effectiveness of content delivery is improved, but the device complexity and space requirements increase
Solution Approach 1:
The viewing area in front of the display is divided into multiple depth-related spatial zones. Each zone is assigned specific content that is relevant to viewers at that distance. The display system segments the visual output so that different portions of content are directed to different spatial zones, allowing one display to serve multiple location-specific functions simultaneously.
Solution Approach 2:
Different regions of the display output are assigned different content qualities and types based on the spatial zone. Content for distant zones may be larger scale or more general, while content for near zones can be more detailed. This local differentiation of content quality ensures each zone receives appropriately tailored information without requiring separate displays.
2Adaptability or versatility
If content is cycled over time on the same display to optimize for specific viewers, then the adaptability to different locations is improved, but the loss of time and viewer frustration increase
Solution Approach 1:
Instead of cycling content through time, the system segments content spatially by depth zone. Multiple location-optimized content versions are displayed simultaneously in different spatial regions, allowing each viewer to immediately see content relevant to their position without waiting for their turn in a content rotation sequence.
Solution Approach 2:
The display continuously presents all location-specific content versions simultaneously rather than cycling through them sequentially. This continuous presentation ensures that every viewer, regardless of position or arrival time, can immediately access relevant content without experiencing delays or missed opportunities.
3Quantity of substance
If all desired content is included on a single display, then the completeness of information is improved, but the viewing quality and intelligibility deteriorate due to size constraints
Solution Approach 1:
The total content is segmented into multiple portions, each optimized for a specific depth zone. This segmentation allows each content portion to be displayed at an appropriate scale and detail level for its intended viewing distance, rather than forcing all content into a single uniform scale that compromises readability for any particular viewer position.
4Quantity of substance
If a single display shows all content simultaneously, then the completeness of information is improved, but the content becomes incompatible, distracting, or overcrowded
Solution Approach 1:
Different content types and messages are segmented and assigned to different spatial zones based on their compatibility and target audience. This spatial separation prevents incompatible or potentially distracting content from appearing simultaneously in the same visual field, while still allowing diverse content to be presented across the full range of zones.

AI summary
A system and method for simultaneously displaying, in plural spatially distinct zones via a multi-view display, differentiated content is disclosed. In accordance with the method, a plurality of spatially distinct zones are defined, differentiated content is assigned to the zones, a location for at least some of plural landing spots of beamlets projected by multi-view pixels of the multi-view display is estimated, the spatially distinct zone in which each said landing spots resides is determined, and beamlets associated with said some landing spots are driven to cause an appropriate content portion to be viewable at said some landing spots, as a function of location in a particular spatially distinct zone.
