Crowd Information Generation for Gathering Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack the ability to effectively notify users of incidents or events at locations where people are gathering, especially for unforeseen or unadvertised events, limiting the provision of relevant information to users.
Innovation Solution
An information provision system that includes a terminal device and an information provision device capable of communicating with each other, managing head count information, generating crowd information based on head count data, and transmitting this information to the terminal device for display on a map, allowing users to identify locations with significant gatherings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If head count information is collected and managed for each position to generate crowd information, then users can be informed about incidents or events at gathering locations, but the system complexity and data management burden increase
Solution Approach 1:
The patent introduces an information provision device as an intermediary between terminal devices and users. This mediator collects head count information from multiple terminal devices, processes it to generate crowd information, and provides it to users. This resolves the contradiction by centralizing data management functions, reducing individual device complexity while preventing information loss about gathering locations.
Solution Approach 2:
The system segments the information provision function into distinct components: terminal devices that collect position data, an information provision device that processes head count information, and display functions that present crowd information. This segmentation allows each component to have specialized, simpler functionality while the overall system achieves comprehensive information gathering and notification capabilities.
2Loss of information
If crowd information is transmitted to terminal devices for display on map images, then users can identify locations with significant gatherings, but the quantity of data transmission and processing increases
Solution Approach 1:
The information provision device extracts only the essential crowd information (positions with significant gatherings) from the complete head count data set. Instead of transmitting all raw head count information, the system identifies and transmits only locations where gatherings occur, significantly reducing data transmission volume while preserving the critical information users need to identify gathering locations.
3Measurement precision
If the system manages detailed head count information including biometric and motion data, then the precision of gathering detection improves, but the data management complexity and privacy concerns increase
Solution Approach 1:
The system uses terminal devices as copies or proxies for collecting detailed user information including biometric and motion data. The actual terminal devices perform the complex data collection and initial processing, while the information provision device receives and processes aggregated head count information. This copying approach allows high-precision gathering detection through detailed data collection while distributing data management complexity across multiple devices rather than concentrating it in one system.

AI summary
An information provision system includes a terminal device, and an information provision device that can communicate with the terminal device. The information provision device includes a communicating section configured to communicate with the terminal device, a head count information managing section configured to manage current head count information for each position, and a crowd information generating section configured to determine a position for making a notification display based on the managed head count information, and generate crowd information containing information of the determined position, and a transmission control section configured to transmit the generated crowd information from the communicating section to the terminal device. The terminal device includes a communicating section configured to communicate with the information provision device, and a control section configured to execute display of a map image on a display section, and execute a display based on the transmitted crowd information on the map image.
