Rotating 2D Graphical Object for Intuitive Vehicle Menu Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In motor vehicles, existing display systems often distract drivers with complex menu structures and information presentation, impairing safe driving by requiring attention away from the road during navigation or device operation.
Innovation Solution
A method and display device that rotates a two-dimensional graphical object on the screen from one side to the other, ensuring the object remains fully displayed and visible, with synchronized axis shifts and rotations, allowing for intuitive and quick comprehension of information, even during vehicle operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If hierarchical menu structures are used to present information, then information organization is improved, but driver distraction and operation complexity increase
Solution Approach 1:
The patent transforms traditional hierarchical menu navigation into a spatial dimension by displaying multiple menu levels simultaneously in a tree structure. Instead of navigating through multiple screens sequentially, all menu options are visible at once in an expanded view, allowing drivers to select any option directly without sequential navigation through intermediate menus.
Solution Approach 2:
The patent segments the information display into multiple simultaneous views showing different menu levels and options within the same display area. The tree structure divides the menu system into hierarchical segments that are all visible at once, with parent menus and child options displayed together rather than requiring separate screens for each level.
2Area of stationary object
If displays are made small to fit vehicle space, then space utilization is improved, but information comprehension speed decreases
Solution Approach 1:
The patent utilizes the full display area by implementing a tree structure that expands horizontally and vertically to fill the available space. Multiple menu levels are arranged in a two-dimensional layout that maximizes the use of every pixel on the display, allowing comprehensive information presentation without requiring a larger physical display.
Solution Approach 2:
The patent merges multiple menu levels and information types into a single integrated view. Instead of requiring separate displays or screens for different menu levels, the tree structure combines parent menus, child options, and contextual information into one unified display that utilizes the entire screen real estate efficiently.
3Loss of information
If complex menu structures are used, then information completeness is improved, but operation time and driver attention increase
Solution Approach 1:
The patent segments the complex menu structure into simultaneously visible sections using a tree layout. All menu options across different hierarchical levels are divided into distinct but visible segments within the same view, allowing drivers to scan and select options without sequentially navigating through multiple screens or menu levels.
Solution Approach 2:
The patent implements a dynamic display that can expand and collapse tree branches based on selection. When a driver hovers over or approaches a menu option, the relevant subtree automatically expands to show available choices, while unrelated sections remain collapsed. This dynamic behavior adapts the information presentation to the driver's immediate needs, reducing cognitive load and operation time.

AI summary
In a method for displaying information in a motor vehicle, at least one two-dimensional object is displayed graphically in a first representation which shows one side of the object, and in a second representation which shows the other side of the object, with the aid of a display mounted in the motor vehicle, different information being shown on the respective sides of the two-dimensional graphical object, and the graphical object extending substantially over the entire size of the display in at least one direction in the first and/or second representation. The representation of the graphical object is altered as a function of a control signal such that the graphical object rotates from one side to the other side in a perspective representation on the display, the two-dimensional graphical object always being fully displayed, at least perspectively, during the rotation. A corresponding display device for a motor vehicle is provided for performing the method.
