Multi-Surface Vehicle Display Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In modern transportation vehicles, the existing display systems often use multiple screens to present navigation and other data, which can be confusing for drivers, especially when trying to minimize attention diversion from traffic events, and there is a need for a unified and intuitive way to display information across multiple display surfaces.
Innovation Solution
A method and system for a transportation vehicle display system with at least two display surfaces that generate coherent map excerpts based on navigation data, where the arrangement of the surfaces determines the geographical relationship of the displayed data, allowing for easy comprehension and adaptation to different operating modes, including user input and automatic changes based on driving parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple display surfaces are used to present navigation data, then the information coverage is improved, but the driver's attention is diverted from traffic events
Solution Approach 1:
The navigation display is segmented across multiple display surfaces (first and second display surfaces), with each surface showing specific map excerpts. The first display surface shows a first map excerpt and the second display surface shows a second map excerpt, dividing the overall navigation information into manageable segments that reduce cognitive load while maintaining comprehensive coverage
Solution Approach 2:
Different display surfaces are assigned different levels of importance and information types based on their location. The first display surface (typically closer to the driver) displays more critical navigation information such as current position and immediate route guidance, while the second display surface displays supplementary information, creating a hierarchical information structure that optimizes driver attention
2Area of stationary object
If multiple display surfaces show different map excerpts, then the geographical coverage is improved, but the coherence of the display is reduced
Solution Approach 1:
Multiple map excerpts displayed on different surfaces are merged to form a coherent overall representation. The system ensures that the first map excerpt on the first display surface and the second map excerpt on the second display surface together create a unified geographical view, with seamless transitions and consistent visual styling that maintains display coherence across surfaces
Solution Approach 2:
The display system transitions from a single-dimensional display to a multi-dimensional display architecture, utilizing spatial arrangement of multiple display surfaces to represent geographical relationships. The relative positions of display surfaces correspond to geographical relationships in the map excerpts, adding a spatial dimension that enhances coherence
3Adaptability or versatility
If the display system adapts to different operating modes, then the versatility is improved, but the system complexity is increased
Solution Approach 1:
The display system dynamically adapts its configuration based on detected operating modes (e.g., driving mode, parking mode, navigation mode). The system can switch between different display configurations, adjust which surfaces are active, and modify the content displayed on each surface according to the current operating mode, providing versatility without requiring multiple fixed systems
Solution Approach 2:
The display system is designed with universal functionality to handle multiple operating modes and information types using the same hardware infrastructure. The control unit can configure the first and second display surfaces to serve different functions depending on the mode, allowing a single system to perform multiple roles (navigation, entertainment, vehicle information) without adding separate dedicated systems

AI summary
A method for operating a display system in a transportation vehicle having at least one first display surface and one second display surface, wherein the display surfaces are spaced apart from one another and the display system has a first and a second operating mode. Navigation data are acquired and a map display is generated based on the acquired navigation data, wherein the map display has a current position of the transportation vehicle. Display data for at least one first component display and a second component display are generated based on the map display, wherein the first component display is displayed by the first display surface and the second component display is displayed by the second display surface. The first component display has a first map excerpt, and the second component display has a second map excerpt. Also disclosed is a display system in a transportation vehicle.
