Adaptive Campfire Display for Shared 3D Viewing and Annotation
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 multiple passengers, do not support annotation and interaction with virtual holographic images, and require constant adjustment due to passenger height and position variations.
Innovation Solution
A system comprising an image chamber with multiple displays and reflectors that project images to passengers, a transparent display for interaction, and sensors for adjusting based on passenger movements, allowing a centrally floating image with interactive annotation capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a screen or monitor is mounted within the vehicle for viewing by passengers, then passengers can view entertainment content, but the system cannot provide a centrally located floating three-dimensional image viewable by multiple passengers simultaneously
Solution Approach 1:
A transparent display acts as an intermediary between the virtual holographic image and the passengers, allowing the image to appear centrally located and floating while enabling multiple passengers to view it simultaneously from different positions within the vehicle compartment
2Loss of information
If current virtual holographic image systems are used, then three-dimensional images can be displayed, but the systems do not include the ability for annotation and for information to be presented with the virtual holographic image
Solution Approach 1:
The transparent display merges multiple functions into a single device: it displays the virtual holographic image, presents annotation information, and provides a touch interface for user interaction, eliminating the need for separate display systems for each function
3Adaptability or versatility
If inverse head-up-display architectures with beams splitters are used, then virtual holographic images can be displayed, but the systems must be constantly re-adjusted to accommodate height and position variations of passengers
Solution Approach 1:
The system incorporates sensors that automatically detect passenger position and height variations, and the transparent display automatically adjusts its parameters to maintain optimal viewing conditions, eliminating the need for manual re-adjustment by users
