Multi-Resolution POI Boundary Identification in Digital Map Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital map rendering systems often misplace or ambiguously indicate points of interest (POIs), leading to user confusion and difficulty in locating the actual POI, as location indicators may be rendered in incorrect positions or nearby locations.
Innovation Solution
A method for multi-resolution point of interest boundary identification in digital map rendering, which involves receiving POI selection indications, generating and overlaying POI boundary data based on the physical shape of the structure or region associated with the POI, and performing map resolution analysis to accurately display the POI boundary on the map, ensuring correct location identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a pin or location indicator is placed at or near a point of interest, then the POI can be indicated on the map, but the location indicator may be misplaced or ambiguous, leading to user confusion
Solution Approach 1:
The patent segments the POI indication into multiple components: boundary data defining the POI extent, entrance data identifying specific access points, and location indicator data showing precise positioning. This segmentation allows each element to serve a specific function, eliminating the ambiguity of a single pin placement and enabling users to understand both the POI boundaries and exact entrance locations.
Solution Approach 2:
The patent transitions from traditional two-dimensional map display to multi-dimensional representation by overlaying boundary data and entrance data on top of the base map. This adds vertical layering of information, where users can see the POI boundary as a distinct layer with marked entrances, providing spatial context that a simple pin cannot convey.
2Loss of information
If location indicators are placed in streets or building complexes near the POI, then the POI can be indicated, but the actual POI location becomes ambiguous and difficult to locate
Solution Approach 1:
The patent performs preliminary action by pre-defining and storing boundary data and entrance data for each POI before the user queries it. When a user searches for a POI, the system immediately retrieves and displays the pre-prepared boundary and entrance information, eliminating the need for users to manually search or interpret ambiguous pin locations, thus saving time and preserving location accuracy.
Solution Approach 2:
The patent introduces boundary data and entrance data as intermediary elements between the POI and the user. These intermediaries provide contextual information that mediates the relationship between the location indicator and the actual POI, clarifying which building or structure the POI belongs to and where to access it, thereby preventing misinterpretation.
3Device complexity
If traditional pin-based location indicators are used, then the map rendering is simple, but the indicators may be rendered in incorrect positions or nearby locations, causing user confusion
Solution Approach 1:
The patent merges multiple data types (boundary data, entrance data, and location indicator data) into a unified POI representation system. Instead of using separate elements for each aspect, the system combines them into an integrated display where the boundary overlay and entrance markers work together with the location indicator, ensuring that all information is presented cohesively and reliably.
Solution Approach 2:
The patent utilizes color changes to differentiate between various POI elements. Boundary data is displayed with distinct coloring to indicate the POI extent, while entrance data uses different colors or markers to identify specific access points. This color differentiation helps users quickly distinguish between POI boundaries and entrances, improving reliability without significantly increasing rendering complexity.
