Navigation Map Item Differentiation via Color Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems face difficulties in allowing users to distinguish between multiple items of the same category, such as POIs or traffic information signs, when using voice commands, as these items are often graphically displayed in a similar manner, making it challenging for drivers to select a specific item during high driving loads.
Innovation Solution
The method involves associating each item on the navigation map with unique graphic attributes, such as different shapes, patterns, or colors, allowing users to select items using voice commands by recognizing the distinct attributes, thereby facilitating easy identification and selection of specific items among a group.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple POIs or traffic information signs of the same category are displayed with similar graphical icons, then the navigation map maintains visual consistency and simplicity, but users cannot easily distinguish between individual items when using voice commands during high driving loads
Solution Approach 1:
The patent applies color changes by assigning different background colors to icons representing the same category of POIs or traffic information signs. This allows users to visually distinguish between individual items while maintaining the same icon type, enabling accurate voice command selection without compromising visual consistency of the navigation map.
Solution Approach 2:
The patent changes visual parameters of icons by modifying background colors or patterns while keeping the icon shape and type consistent. This parameter change enables differentiation between multiple items of the same category, allowing users to identify and select specific items through voice commands even when driving load is high.
2Reliability
If multiple items of the same category are displayed with identical icons, then the display remains simple and consistent, but drivers experience difficulty in selecting specific items during high driving loads
Solution Approach 1:
The patent implements reliable item selection by assigning distinct background colors to different items of the same category. This simple visual differentiation mechanism enhances selection accuracy without significantly increasing device complexity, as it only requires modifying the color parameter of existing icons.
Solution Approach 2:
The patent applies local quality by modifying only the background color or pattern of specific icons while keeping the overall icon design and navigation map structure consistent. This localized visual differentiation improves item distinguishability without requiring complex system-wide changes.
3Object-affected harmful factors
If voice commands are used for item selection during high driving loads, then driver safety is improved by reducing touch operations, but the ability to accurately select among multiple similar icons is reduced
Solution Approach 1:
The patent reduces driver distraction by enabling voice command selection, and simultaneously improves item identification ease by assigning distinct background colors to different icons. The visual differentiation allows drivers to quickly identify target items and confirm voice command selections without requiring close visual inspection or complex touch operations.
Solution Approach 2:
The patent enhances voice command operation by providing visual feedback through distinct background colors. When a driver issues a voice command, the system can highlight or emphasize the target icon with a distinctive background color, confirming accurate item identification and reducing driver distraction through clear visual confirmation.

AI summary
A method and an apparatus of displaying a plurality of items on a map includes selecting the plurality of items, associating the plurality of items with a plurality of graphic attributes respectively in a manner that two items of the plurality of items are associated with different graphic attributes, and displaying the plurality of items using the plurality of graphic attributes, thus, the method of displaying the plurality of items on the map allows a user to distinguish the plurality of items by graphic attributes while at least one of the plurality of items is described in voice commands, even if the plurality of items belong to a same group attributes.
