Navigation Map Point Display with Directional Icon
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems face challenges in intuitively displaying additional information about a point on a map, leading to driver distraction due to the crowded nature of map data, making it difficult for drivers to understand the exact location and execute appropriate maneuvers.
Innovation Solution
A method that estimates the position of a point on a navigation map, including the side of the street, and displays this information using an icon that graphically indicates the direction, along with additional details such as building information, street views, ratings, and facility availability, to assist drivers in making informed decisions while minimizing cognitive load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If additional information about a point is displayed on the navigation map, then the information completeness is improved, but the map becomes crowded and harder to read
Solution Approach 1:
The patent segments the additional information into multiple categorical groups (e.g., point information, building information, floor information, facility information). Each category is displayed in a separate designated area on the map, preventing information crowding while maintaining completeness. This segmentation allows drivers to process information in organized chunks rather than overwhelming全部内容.
Solution Approach 2:
The patent utilizes the vertical dimension of the map display by arranging information in stacked designated areas (first designated area, second designated area, third designated area, fourth designated area) rather than spreading information horizontally. This dimensional arrangement preserves map readability while accommodating comprehensive information display.
2Measurement precision
If detailed point information is displayed on the map, then the understanding of exact location is improved, but driver distraction increases
Solution Approach 1:
The patent assigns different visual characteristics to different information categories based on their importance and type. Each designated area uses distinct visual styling (different icons, colors, or formats) to highlight specific information types. This local differentiation helps drivers quickly identify and process critical location information without being overwhelmed by uniform presentation of all data.
Solution Approach 2:
The patent extracts critical location-determining information (such as left/right side indication, building entrance position) and places it in prominent designated areas separate from supplementary information. This extraction ensures that essential navigation-critical information is immediately visible and processable, reducing the cognitive load and distraction for drivers.
3Loss of information
If multiple types of information are displayed simultaneously, then the comprehensiveness is improved, but the cognitive load increases
Solution Approach 1:
The patent divides comprehensive information into four distinct designated areas, each dedicated to a specific information category. This segmentation allows drivers to process information systematically rather than attempting to comprehend all data simultaneously, thereby reducing cognitive load while maintaining information comprehensiveness.
Solution Approach 2:
The patent employs periodic updating of information in the designated areas based on the vehicle's progress along the route. As the vehicle approaches the destination, relevant information is updated and displayed in appropriate areas, while less relevant information is minimized or hidden. This periodic refresh strategy prevents information overload by presenting only currently relevant data.

AI summary
A method and an apparatus of displaying a point on a map of route guidance includes receiving an entry of a user, determining a point based on the entry of the user, determining an address number of the point, retrieving map data indicating a road segment which includes the address number of the point from map information storage, estimating a position of the location based on the street address number of the point and position data of the road segment, and displaying the point with an icon at the estimated position on the map. While estimating the position of the point, a side of the street at which the point is located is estimated and a shape of the icon graphically indicates a direction corresponding to the side of the street at the estimated position.
