Floating 3D Vehicle Display With Beam Splitters and Touch Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle entertainment systems lack the ability to provide a centrally located floating three-dimensional image viewable by all passengers, and do not allow for annotation or tactile interaction with virtual holographic images.
Innovation Solution
A system comprising a display projecting three-dimensional images via beam splitters to each passenger, with transparent touch screens or interfaces for annotation and input, and a monitoring system to adjust image positioning based on passenger head and eye movement, enabling a centrally perceived image with interactive capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single centralized screen is used for all passengers to view, then all passengers can see the same content, but passengers cannot interact with the image and cannot receive personalized information
Solution Approach 1:
The system divides the viewing experience into two segments: a shared virtual holographic image that all passengers can view centrally, and individual transparent touch screens for personalized interaction. This segmentation allows the system to provide both unified content delivery and personalized interaction capabilities simultaneously.
Solution Approach 2:
Transparent touch screens serve as an intermediary between passengers and the virtual holographic image. These touch screens allow passengers to interact with the system while maintaining visibility of the three-dimensional image, enabling interaction without blocking the view.
2Ease of operation
If transparent touch screens are added for interaction, then passengers can interact with the image, but the transparency and clarity of the floating image may be reduced
Solution Approach 1:
The system uses transparent touch screens made from thin, transparent materials that minimize obstruction of the virtual image. These thin-film touch screens provide tactile interaction capabilities while maintaining high transparency to preserve the brightness and clarity of the floating three-dimensional image.
3Adaptability or versatility
If multiple individual screens are provided for each passenger, then personalized viewing is enabled, but a centrally located shared image experience is lost
Solution Approach 1:
The transparent touch screens serve multiple functions: they act as interaction interfaces for personalized input, display individualized information for each passenger, and simultaneously maintain transparency to allow viewing of the shared virtual holographic image. This multi-functionality eliminates the need for separate individual screens while providing personalized viewing capabilities.
