Problem
Current vehicle entertainment systems lack the ability to provide a centrally located, interactive, and augmented reality-enhanced floating three-dimensional image that can be viewed by multiple passengers, and do not support annotation or tactile interaction with virtual holographic images.
Innovation Solution
A system comprising an image chamber with displays and reflectors to project three-dimensional images centrally, a transparent display for private information, and an augmented reality display on the vehicle window, along with sensors and gesture recognition to enable interactive gaming and personalized content display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If current virtual holographic image systems are used, then floating images can be displayed, but annotation and additional information cannot be presented with the virtual holographic image
Solution Approach 1:
The patent combines multiple display technologies into a single integrated system. The transparent display overlay is merged with the virtual holographic image chamber, allowing annotations and additional information to be displayed simultaneously with the 3D holographic content without requiring separate display devices. This merging enables comprehensive information presentation while maintaining a unified system architecture.
Solution Approach 2:
The patent adds a transparent display overlay dimension that exists in front of the virtual holographic image space. This creates a multi-layered display architecture where the first layer presents the 3D holographic content and the second transparent layer provides annotation and information overlays, effectively adding another dimension of information presentation without interfering with the underlying holographic display.
2Adaptability or versatility
If inverse head-up-display architectures with beam splitters are used, then virtual images can be displayed, but constant re-adjustment is required to accommodate passenger position variations
Solution Approach 1:
The system incorporates sensors that automatically detect passenger position and eye tracking data, then self-adjusts the virtual holographic image positioning and transparent display overlay alignment without requiring manual intervention. The system serves itself by continuously monitoring passenger location and automatically recalibrating the display parameters to maintain optimal viewing conditions for all passengers.
Solution Approach 2:
The patent implements a feedback mechanism where sensors continuously monitor passenger position, head orientation, and eye gaze direction. This real-time feedback is processed by the control system, which then adjusts the holographic image projection and transparent display positioning to ensure proper alignment and viewing comfort, creating a closed-loop adaptive system.
3Adaptability or versatility
If multiple individual screens are provided for each passenger, then personal viewing is enabled, but a centrally located shared viewing experience cannot be achieved
Solution Approach 1:
The virtual holographic image chamber with transparent display overlay serves multiple functions simultaneously: it provides a shared central viewing experience for all passengers, enables personalized content delivery to individual passengers through position-based rendering, and allows interactive engagement for multiple users. This single multi-functional system replaces what would otherwise require multiple separate display devices for each passenger.
Solution Approach 2:
The system segments the viewing experience by providing different content or perspectives to different passengers based on their position and orientation, while maintaining a unified physical display structure. The transparent display can show personalized information to each passenger simultaneously, and the holographic chamber can render different views for different viewing angles, achieving personalization without requiring separate physical screens for each user.
4Ease of operation
If current entertainment systems are used, then basic viewing functionality is provided, but tactile interaction with virtual images is not available
Solution Approach 1:
The patent introduces a transparent display overlay as an intermediary layer between the passenger and the virtual holographic image. This transparent display serves as a mediator that can detect tactile input (such as touch or gesture) from the passenger and translate it into interactive commands that control the virtual holographic content, enabling tactile interaction without requiring direct physical contact with the virtual image itself.

AI summary
A method of using a system for generating a centrally located floating image display includes displaying a first image with a first display, receiving the first image with a first reflector, reflecting the first image with the first reflector, displaying, a second image with a second display, receiving the second image with a second reflector, reflecting the second image with the second reflector, displaying first private information to the first passenger and second private information to the second passenger with a transparent display positioned between the first passenger and the first reflector and between the second passenger and the second reflector, receiving input from the first and second passengers with the system controller, collecting images with an external scene camera, and displaying general information with an augmented reality display.
