Vehicle Display Adaptation for Speed-Dependent Object Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems struggle to intuitively and quickly present a large number of graphic objects to drivers, especially at higher speeds, leading to driver distraction and reduced safety.
Innovation Solution
A method and device that adapt display modes based on vehicle speed, using a hysteresis to transition between layouts that arrange graphic objects on a virtual ring at low speeds and in a grid at higher speeds, with animations that converge and diverge to maintain intuitive navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large number of graphic objects are displayed simultaneously on a relatively small display area, then the information completeness is improved, but the detectability of individual objects deteriorates
Solution Approach 1:
The display is segmented into multiple pages, with each page containing a limited number of graphic objects (e.g., 3-5 objects per page). Users can navigate between pages to access additional objects, thereby maintaining detectability while providing access to a large total number of graphic objects across all pages.
Solution Approach 2:
The layout dynamically adapts based on vehicle speed. At low speeds, more graphic objects are displayed per page to provide comprehensive information. At high speeds, fewer objects are displayed per page to enhance detectability, with pagination enabling access to additional objects when needed.
2Productivity
If the display layout is changed to improve information intake speed, then the ease of operation deteriorates due to loss of orientation
Solution Approach 1:
The system prepares multiple pre-defined layout configurations in advance, each optimized for different driving conditions (e.g., stationary, low speed, high speed). When a speed threshold is crossed, the system seamlessly transitions to the pre-prepared appropriate layout, maintaining orientation through consistent object positioning within each layout type.
Solution Approach 2:
The display system automatically detects vehicle speed and self-adjusts the layout configuration without requiring manual user input. This maintains ease of operation by eliminating the need for users to manually switch layouts while still providing optimized information presentation for current driving conditions.
3Ease of operation
If a carousel-like display is used to rotate graphic objects, then the ease of operation is improved for selecting objects, but the information intake speed deteriorates when many objects need to be viewed
Solution Approach 1:
Graphic objects are segmented into multiple pages, with each page displaying a limited set of objects in a carousel format. This maintains ease of operation for selecting objects within a page while preventing information overload. Users can navigate to different pages to access additional objects, thereby improving overall information intake speed.
Solution Approach 2:
The system dynamically adjusts the number of objects displayed per page based on vehicle speed. At low speeds, more objects are shown per page to improve information intake speed. At high speeds, fewer objects are shown per page to maintain ease of selection and detectability, with pagination providing access to additional objects.

AI summary
The present invention relates to a method for displaying information of a plurality of graphical objects (10). Said graphical objects can be displayed by means of a control device (3) of a display device (1) in a first or second display mode. The speed of the vehicle is measured, and in a first speed range the graphical objects (10) are displayed in the first display mode and in a second speed range the graphical objects (10) are displayed in the second display mode. The invention further relates to a device for performing said method.
