Transparent Vehicle Display Orientation for Bidirectional Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous mobility systems lack effective communication capabilities between occupants and external objects based on driving status, limiting the exchange of unidirectional or bidirectional visual information.
Innovation Solution
A vehicle system with a display that adjusts image orientation based on driving status to provide unidirectional or bidirectional visual information to occupants and external objects, using a mode setter and display controller to determine and adjust image orientation according to the visual information provision target.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a transparent display provides unidirectional visual information to external objects, then external objects can perceive images, but communication capability with occupants is diminished
Solution Approach 1:
The display dynamically adjusts its orientation mode between unidirectional (inward-facing for occupants, outward-facing for external objects) and bidirectional based on driving status. The mode setter determines the appropriate visual information provision target according to driving status, and the display controller adjusts image forward orientation accordingly, enabling the display to adapt between different communication needs without physical reconfiguration.
Solution Approach 2:
The system changes the orientation parameter of the displayed image based on driving status. When driving status indicates external communication is needed, the image orientation is adjusted to outward direction; when occupant communication is prioritized, orientation shifts to inward direction. This parameter change enables flexible information provision without hardware modification.
2Loss of information
If image orientation is adjusted for different visual information provision targets, then communication capability is enhanced, but system complexity increases
Solution Approach 1:
The existing transparent display structure is made multi-functional by enabling it to serve both occupant communication and external object communication purposes. Through software-based orientation adjustment controlled by the mode setter and display controller, the same physical display performs different communication functions based on driving status, avoiding the need for multiple separate display systems.
Solution Approach 2:
The mode setter continuously monitors driving status and provides feedback to the display controller to adjust image orientation accordingly. This closed-loop control ensures the display adapts automatically to changing communication needs based on real-time driving conditions, reducing manual intervention and simplifying user interaction despite the underlying system complexity.

AI summary
A vehicle includes a display, a mode setter determining a visual information provision target of an image displayed on the display according to a driving status and setting forward orientation of the image on the display according to the visual information provision target, and a display controller selecting an image corresponding to the driving status and displaying the image on the display after adjusting the forward orientation of the selected image to the inward direction, outward direction, or both directions of the display according to the forward orientation set by the mode setter.
