Indoor Map POI Prioritization for Ghost-Click Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing map applications face challenges in displaying indoor maps of complex buildings, such as large shopping malls, due to overlapping points of interest (POIs) leading to malfunctions like ghost clicks and degraded user experience.
Innovation Solution
A method and system that determine POIs to be displayed on a map screen based on priority values and popularities, prioritizing certain POIs when the background and indoor maps overlap, using contention processing to prevent malfunctions and enhance user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all POIs are displayed on the indoor map, then the completeness of information is improved, but the user experience deteriorates due to overlapping POIs and malfunctions like ghost clicks
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the visibility and display parameters of POIs based on their priority values and popularity metrics. High-priority POIs are displayed with higher visibility while lower-priority POIs are suppressed or shown with reduced prominence, resolving the contradiction between displaying all information and maintaining reliable user interaction.
Solution Approach 2:
The patent implements local quality by applying different display treatments to different POIs based on their individual characteristics. Each POI is evaluated independently and assigned specific display properties (visible, hidden, or reduced prominence) based on its priority and popularity, allowing important POIs to be clearly visible while preventing overlapping issues with less important POIs.
2Loss of information
If multiple POIs are displayed simultaneously in overlapping areas, then the information coverage is improved, but malfunctions such as ghost clicks occur
Solution Approach 1:
The patent changes the display parameter of POIs from a binary visible/hidden state to a multi-level state including visible, hidden, and reduced prominence. This allows the system to maintain information coverage by keeping all POI data available while preventing harmful overlaps by adjusting the display prominence of conflicting POIs based on their priority and popularity values.
Solution Approach 2:
The patent creates a composite display layer that combines background map POIs and indoor map POIs with different transparency and prominence levels. This composite approach allows both layers to coexist without causing ghost clicks, as the system dynamically adjusts which POI layer takes precedence in overlapping regions based on the calculated priority and popularity metrics.
3Loss of information
If the indoor map is displayed over the background map, then the detail information is improved, but errors and malfunctions occur during simultaneous display
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the z-index, transparency, and visibility parameters of POIs from the indoor map versus the background map. Based on priority and popularity calculations, the system determines which map layer's POIs should be prominently displayed and which should be suppressed, resolving conflicts and ensuring stable display without errors or malfunctions.
Solution Approach 2:
The patent implements dynamics by making the display configuration adaptive rather than static. The system continuously evaluates the priority and popularity of POIs from both maps and dynamically adjusts which POIs are visible, hidden, or shown with reduced prominence. This dynamic adjustment prevents display errors and malfunctions by ensuring that only appropriate POIs are actively displayed at any given time.

AI summary
A method of providing an indoor map is provided. The method includes transmitting, the background map information to a user terminal, wherein the background map information includes a background map and a plurality of first points of interest (POIs), receiving a request for indoor map detail information for at least one first POI, which is a display target of an indoor map, determining, based on priority values of the plurality of first POIs and priority values of a plurality of second POIs of the indoor map of the at least one first POI, one or more third POIs to be displayed on a map screen, and transmitting the indoor map detailed information to the user terminal, wherein the indoor map detailed information includes floor polygon information of the first POI, which is a display target of the indoor map, and the determined one or more third POIs.
