Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle navigation systems do not allow multiple passengers to interact collaboratively with a floating three-dimensional map image, lacking annotation capabilities and tactile interaction, and require frequent adjustments of inverse head-up-display architectures to accommodate varying passenger positions.
Innovation Solution
A system that uses a combination of displays, reflectors, and a transparent touch screen to project a centrally floating three-dimensional map image, allowing multiple passengers to interact and share navigation decisions, with augmented reality displays and light-emitting particles on windows to create an edge-to-edge augmented reality view, and sensors to track passenger head and eye movements for dynamic image adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-occupant navigation system is used, then the system complexity is low, but multiple passengers cannot interact collaboratively with the navigation display
Solution Approach 1:
The system divides the navigation display into multiple independent holographic image chambers, each serving a specific passenger. Each chamber contains its own display and optical components, allowing multiple passengers to simultaneously view and interact with separate navigation displays while maintaining individualized viewing angles and information privacy.
Solution Approach 2:
The system creates a universal navigation platform that serves multiple functions: displaying navigation information to multiple passengers simultaneously, enabling collaborative decision-making, providing private information display for each passenger, and accommodating various interaction methods (touch, gesture, voice).
2Adaptability or versatility
If inverse head-up-display architecture with beam splitters is used, then virtual holographic images can be displayed, but the system requires constant re-adjustment to accommodate passenger height and position variations
Solution Approach 1:
The system employs dynamic adjustment mechanisms including movable mirrors and adjustable optical components within each holographic image chamber. These components can be automatically repositioned based on sensor data detecting passenger position and height, allowing the system to adapt to varying passenger configurations without manual intervention.
Solution Approach 2:
The system incorporates sensors that continuously monitor passenger position, height, and viewing angle. This feedback information is processed by a control system that automatically adjusts the optical components and holographic image parameters to maintain optimal viewing conditions for each passenger.
3Ease of operation
If current virtual holographic systems are used, then three-dimensional map images can be displayed, but annotation capabilities and tactile interaction are lacking
Solution Approach 1:
The system introduces a transparent touch-sensitive display as an intermediary between the passenger and the holographic image. This transparent display allows passengers to touch and interact with the virtual image as if it were a physical object, enabling intuitive selection, annotation, and manipulation of navigation elements while maintaining the three-dimensional holographic visualization.

Implementation Method 1
reflecting, with the first reflector, the first map image to the first passenger, wherein the first passenger perceives the first map image floating at a central location within the image chamber
Implementation Method 2
reflecting, with the second reflector, the second map image to the second passenger, wherein the second passenger perceives the second map image floating at the central location within the image chamber
Implementation Method 3
the light emitting particles in the windscreen emit visible light in response to absorbing the excitation light
