Vehicle List Scrolling with Dynamic Transparency and Pivoting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for displaying information in vehicles, particularly when scrolling through lists, often distract drivers due to complex presentation and require prolonged gaze, as they do not efficiently manage list entry transitions and visibility.
Innovation Solution
A method where list entries are moved with interpolated intermediate images, changing position, size, and transparency, using a combination of pivoting and translational movements outside the display area, ensuring a fluid animation without rotation, and highlighting essential elements for quick user orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If list entries are displayed with complex presentation and traditional scrolling, then information can be displayed, but driver distraction increases and information capture time extends
Solution Approach 1:
The list is divided into multiple pages with a limited number of entries visible at once. During scrolling, only the currently selected list entry is fully visible and readable, while other entries are partially obscured or hidden. This segmentation ensures that the driver's attention is focused on one piece of information at a time, reducing cognitive load and distraction.
Solution Approach 2:
Different visual properties are applied to different parts of the display based on their importance. The selected list entry has full opacity and clarity, while non-selected entries have reduced opacity or are partially hidden. This local differentiation in visual quality helps the driver quickly identify important information without being overwhelmed by all displayed content.
2Productivity
If traditional scrolling is used, then list entries can be changed, but the transition requires prolonged gaze and reduces safety
Solution Approach 1:
The display transitions between list entries using dynamic animation effects rather than static, abrupt changes. List entries smoothly transition in and out of view with fading effects and positional movements. This dynamic presentation allows the driver's eye to track the changing information more naturally and quickly, reducing the time needed to process each entry while maintaining clarity.
Solution Approach 2:
During scrolling transitions, non-selected list entries are quickly faded out or moved out of the visible area, allowing the display to 'skip' through less important information rapidly. This rushing through of secondary information minimizes the time the driver needs to spend processing each entry, while the selected entry remains clearly visible for immediate comprehension.
3Ease of operation
If perspective movements are applied during scrolling, then visual interest is increased, but readability may be compromised
Solution Approach 1:
While perspective movements and 3D effects are applied to create visual interest and help users understand the scrolling direction, these effects are selectively applied only to non-selected list entries. The currently selected entry maintains perfect clarity, proper orientation, and optimal readability without any distracting perspective distortions. This local application of visual effects preserves both engagement and readability.
Solution Approach 2:
The perspective effects are applied dynamically during transition animations rather than being static. As list entries move in and out of the selected position, they exhibit subtle 3D transformations that provide visual feedback about the scrolling direction and state. However, once an entry becomes the selected entry, these dynamic perspective effects are removed or minimized to ensure maximum readability.

AI summary
The present invention relates to a method for displaying information on a display area (1), in particular in a vehicle, in which at least a subset of a list having a plurality of list entries (16) is displayed, and while scrolling through the list the subset changes so that list entries (16) disappear and new list entries (16) are displayed instead. The method according to the invention is characterised in that the position, the size and the transparency of the displayed list entries (16) are changed during scrolling.
