Dynamic Magnification List Scrolling for Vehicle Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles, scrolling through long lists of information requires significant time and attention from the driver, as they need to navigate back to the list entries to select different entries, leading to driver distraction and increased risk.
Innovation Solution
A method and device that allow users to select and scroll through list entries and their associated elements directly, without needing to return to the list, by adjusting the magnification factor based on the operating situation, enabling quicker access to other list entries through touch-sensitive or mechanical interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional scrolling methods are used to navigate through long lists in vehicles, then complete list navigation is achieved, but driver distraction and navigation time increase significantly
Solution Approach 1:
The patent applies dynamics by making the magnification factor adjustable based on the operating situation. The display system dynamically changes the magnification level - using higher magnification when the vehicle is stationary or moving slowly (allowing detailed view) and lower magnification when moving quickly (enabling faster scrolling through more items per screen). This dynamic adaptation resolves the contradiction between viewing completeness and navigation speed.
Solution Approach 2:
The patent changes the magnification parameter according to operating conditions to optimize the balance between list visibility and scrolling efficiency. By adjusting this parameter, the system allows drivers to view more list entries per screen when needed, reducing the number of scroll actions required and thereby reducing navigation time and driver attention requirements.
2Productivity
If the display shows more list entries at once, then navigation time decreases, but the detail visibility of each entry is reduced
Solution Approach 1:
The system dynamically adjusts the magnification factor based on the operating situation, allowing the display to show more or fewer list entries depending on current needs. When the vehicle is stationary or moving slowly, higher magnification provides detailed visibility. When moving quickly or when navigation speed is prioritized, lower magnification displays more entries, improving scrolling efficiency while maintaining the ability to access details when needed.

AI summary
In a method for displaying information arranged in lists, a portion of a list is displayed in a display area, which includes a plurality of list entries, multiple elements being associated at least in part with the list entries, the displayed portion of the list being modifiable by a scrolling action such that previous and subsequent list entries are displayable in succession, and, when a list entry is selected, this list entry is displayed together with at least a portion of the elements that are associated with the list entry. If a selected list entry is displayed together with at least a portion of the elements associated with the selected list entry and the scrolling action is performed, first previous or subsequent elements are displayed in succession and thereupon list entries preceding or following the selected list entry are displayed. A device is configured for implementing the method.
