Transmission Optical Element Orthogonal Information Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transmission-type optical devices, such as head-mounted displays and projection mapping, face challenges in allowing multiple observers to share information simultaneously and in separating external information from projected information, leading to reduced visibility and mixed perception of both.
Innovation Solution
A transmission-type optical element with a substrate and information forming units that allow transmissivity in one direction while forming distinct information elements on orthogonal surfaces, enabling observers to view external information and information provided by the element as separate entities, with control systems for adjusting the optical element's position relative to the scene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information is displayed on a transmission-type display (head mounted display), then information visibility is improved, but external information visibility deteriorates
Solution Approach 1:
The invention transitions from displaying information on a flat transmission-type display surface to forming information elements on the side surfaces of three-dimensional information forming units. This dimensional change allows light to pass through the transparent substrate while reflecting off the side surfaces to display information, enabling both external visibility and information display simultaneously without the trade-off present in conventional transmission-type displays
2Productivity
If projection mapping directly projects videos on a structure, then information delivery is improved, but information separation deteriorates
Solution Approach 1:
The invention segments the display surface into multiple information forming units, each with side surfaces that can independently form information elements. This segmentation allows different regions to display different information content, enabling clear separation between structure-related information and projected information, unlike conventional projection mapping where all information is mixed on a single surface
3Ease of operation
If a transmission-type device is attached to an individual observer, then information display is improved, but information sharing deteriorates
Solution Approach 1:
The invention creates a universal information display system through transparent substrates with information forming units that can be integrated into various structures (buildings, vehicles, objects) rather than being limited to individual head-mounted devices. This allows multiple observers to simultaneously view the same information or different information displayed on different side surfaces, enabling both individualized and shared information access
