Vehicle List Navigation With Boundary Feedback and Soft Stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle operating systems with lists that have a start and end require users to scroll through the entire list to switch between elements, wasting time and requiring high attention to avoid missing the list boundaries, while endless lists that cycle back to the start can be distracting.
Innovation Solution
An operating system that displays lists as endlessly rolling, with visual, acoustic, and haptic signals at the list start and end, allowing users to pause and resume scrolling after a specified interval, enabling quick navigation without full attention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If list elements are displayed as an endless rolling list that cycles from end to start, then navigation continuity is improved, but user attention requirement increases
Solution Approach 1:
The patent applies periodic action by implementing a soft stop mechanism that pauses the continuous list scrolling at list boundaries (start and end positions). This periodic interruption allows users to perceive boundary conditions without completely stopping the endless list functionality, thus maintaining navigation continuity while reducing the attention required to detect list boundaries.
Solution Approach 2:
The patent implements feedback by providing optical, acoustic, and/or haptic signals when the list run reaches or approaches the start or end of the list. This feedback mechanism informs users of list boundaries without requiring continuous attention, resolving the contradiction between endless list navigation and user attention requirements.
2Loss of information
If list run is automatically stopped at list start or end, then user awareness of boundaries is improved, but navigation efficiency decreases
Solution Approach 1:
The soft stop mechanism applies periodic action by temporarily pausing the list run only at boundary positions rather than continuously. This allows the list to resume scrolling automatically after a specified time interval, maintaining overall navigation efficiency while providing periodic boundary awareness to users.
Solution Approach 2:
The patent applies preliminary action by providing advance notice to users through optical, acoustic, and/or haptic signals before the list run is stopped at boundaries. This allows users to anticipate the pause and prepare for it, reducing the perceived disruption to navigation flow while still providing boundary awareness.
3Device complexity
If users must scroll through entire list to switch between elements, then list structure simplicity is maintained, but operation time increases
Solution Approach 1:
The patent applies dimensionality change by implementing direct transition functionality that allows users to jump between list elements in a different dimensional space (from sequential scrolling to direct position jumping). This maintains the simple linear list structure while adding a new navigation dimension that significantly reduces element selection time.
Solution Approach 2:
The patent introduces an intermediary mechanism (the control device with memory function) that stores and recalls list element positions. This intermediary allows users to quickly navigate between elements by recalling stored positions rather than scrolling through the entire list, reducing operation time without complicating the fundamental list structure.

AI summary
The present invention proposes an operating system for a vehicle, wherein the operating system comprises a display device with a display surface, a storage device for storing list items sorted in a list with a list start and a list end, an input element for selecting a list item by a user, and a control device coupled to the display device and the input element, with which a display on the display surface can be controlled, wherein the display surface can be controlled by the control device in such a way that at least a part of the list items on the display surface is displayed in the form of an endlessly rolling list, and such that a change between selected list items can be realized by a list cycle in a list cycle direction initiated by an actuation process on the input element.that when the beginning or end of the list is reached, the list iteration in the previous direction is stopped.
