Vehicle Navigation Scrolling Rate Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle navigation systems face challenges in allowing users to review content lists while driving, as scrolling through lists can be too fast or contain too many items, diverting the driver's attention from the road.
Innovation Solution
A method and system that obtain a scrolling input from the user, determine its value, and display content items at a first scrolling rate if the value is greater than a predetermined threshold, allowing for controlled and safe navigation through content lists.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the navigation system displays content lists with multiple items, then the information completeness is improved, but the driver's attention is diverted from the vehicle path
Solution Approach 1:
The patent segments the content list into multiple pages or groups, allowing the driver to access different categories of information (points of interest, restaurants, hotels, etc.) in separate views. This segmentation reduces the cognitive load on the driver by presenting information in manageable chunks rather than overwhelming lists, thus maintaining information completeness while reducing distraction.
Solution Approach 2:
The patent implements dynamic scrolling behavior where the scrolling rate adjusts based on vehicle speed. When the vehicle is stationary or moving slowly, faster scrolling is permitted. When the vehicle is moving quickly, scrolling slows down or is restricted. This dynamic adjustment allows full access to information when safe, while preventing distraction during high-speed operation.
2Productivity
If the navigation system allows fast scrolling through content lists, then the access speed is improved, but the user cannot view and understand the information displayed
Solution Approach 1:
The patent implements dynamic scrolling rate adjustment based on vehicle speed. The system monitors vehicle speed and automatically adjusts the scrolling rate accordingly - slower scrolling at higher speeds, faster scrolling at lower speeds. This ensures that users can comprehend information when it is safe to do so, while still providing efficient access when the vehicle is stationary or moving slowly.
Solution Approach 2:
The patent incorporates feedback mechanisms where the system monitors scrolling behavior and vehicle speed, then adjusts scrolling parameters in real-time. The system provides visual feedback through the display and may provide haptic feedback through the steering wheel controller, allowing users to understand the current scrolling state and make informed decisions about information consumption.
3Reliability
If the navigation system restricts scrolling at speeds above a threshold, then driver safety is improved, but user access to content lists is limited
Solution Approach 1:
The patent implements dynamic access control where scrolling functionality is not completely blocked above threshold speeds, but rather adjusted. The system allows scrolling above the speed threshold but at reduced rates, and may require additional user confirmation for certain actions. This dynamic approach maintains driver safety by preventing rapid interactions at high speeds while still allowing necessary access to critical information.
Solution Approach 2:
The patent changes the parameter of scrolling rate based on vehicle speed parameters. Rather than a binary on/off restriction, the system continuously adjusts scrolling speed, pause duration, and interaction requirements based on the vehicle's current speed. This allows full content list accessibility when safe, with progressively stricter controls as speed increases, maintaining both safety and usability.

AI summary
A method for displaying content items of a navigation system for a vehicle includes the steps of obtaining a scrolling input from a user, determining a value pertaining to the input, and displaying the content items at a first scrolling rate if the value is greater than a predetermined threshold.
