Multiplexed Hologram Display for Shared In-Vehicle 3D Floating Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle entertainment systems lack the ability to provide a centrally located, three-dimensional floating image viewable by all passengers, failing to offer an immersive and unified visual experience.
Innovation Solution
A system comprising a display that projects a multiplexed hologram of three-dimensional images and a set of beam splitters, each associated with a passenger, allowing each to see the image as if it floats centrally, with the option to rotate images for varying perspectives and equipped with head-tracking capabilities for adjustable orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single screen or monitor is mounted within the vehicle for viewing by passengers, then the system achieves its intended purpose of providing entertainment, but it fails to provide a centrally located three-dimensional floating image viewable by all passengers
Solution Approach 1:
The system segments the holographic image into multiple views, with each beam splitter receiving and directing a specific perspective to individual passengers. This segmentation enables each passenger to perceive a unique three-dimensional perspective of the same object, creating a unified yet personalized viewing experience for all passengers
Solution Approach 2:
Beam splitters serve as intermediary optical elements between the single holographic display and multiple passengers. Each beam splitter redirects the holographic image to its associated passenger, enabling the system to provide centrally located three-dimensional floating images viewable by all passengers without requiring multiple displays
2Ease of operation
If beam splitters are made transparent to allow passengers to see through them, then passenger visibility is improved, but the beam splitter structure becomes more complex
Solution Approach 1:
The beam splitters are designed with transparent properties specifically at the locations where passengers need to see through them, while maintaining their optical reflecting functionality for directing holographic images. This local quality optimization allows passengers to see both the floating image and through the beam splitter to the vehicle interior
3Adaptability or versatility
If the display projects a multiplexed hologram with multiple three-dimensional holographic images, then passenger engagement is enhanced, but the use of energy increases
Solution Approach 1:
The display projects multiple three-dimensional holographic images in a multiplexed sequence rather than simultaneously, with each beam splitter receiving different images at different times. This periodic action allows the system to enhance passenger engagement with multiple perspectives while managing energy consumption by activating only one holographic image at a time
