Geofence Content Provision via Adaptive Angle Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing geofence-based services often fail to appropriately provide information to users entering or exiting designated areas due to issues like incorrect boundary settings, GPS measurement errors, and inappropriate content delivery.
Innovation Solution
An information providing device and system that stores area designation information and angle threshold values, acquires user terminal position information, specifies entry and exit angles, adjusts threshold values based on conditions, and controls content provision to ensure accurate and timely information delivery to users within or outside geofences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed angle threshold value is used for geofence entry/exit detection, then the system is simple to operate, but GPS measurement errors cause inappropriate content provision
Solution Approach 1:
The patent applies dynamics by making the angle threshold value adjustable rather than fixed. The system dynamically adjusts the angle threshold based on GPS measurement accuracy and area characteristics, allowing the threshold to adapt to different conditions. This resolves the contradiction by enabling the system to maintain high reliability through adaptive thresholds while keeping the base system relatively simple.
Solution Approach 2:
The patent changes the angle threshold parameter based on GPS measurement accuracy and area characteristics. By adjusting this parameter dynamically, the system can compensate for GPS errors and provide content more accurately. This directly addresses the technical contradiction by using parameter changes to improve reliability without requiring complete system redesign.
2Reliability
If the angle threshold value is adjusted to accommodate GPS errors, then content provision reliability improves, but the device complexity increases
Solution Approach 1:
The system performs self-service by automatically adjusting the angle threshold based on GPS measurement accuracy and area characteristics without requiring manual intervention. The server autonomously calculates and updates thresholds, reducing the need for complex manual configuration mechanisms while improving detection accuracy.
Solution Approach 2:
The system uses feedback from GPS measurement accuracy data to continuously optimize the angle threshold. By monitoring actual GPS performance and area characteristics, the system adjusts thresholds to maintain optimal detection accuracy, reducing the need for overly complex predetermined adjustment mechanisms.
3Productivity
If a strict angle threshold is used, then false detections are reduced, but users entering/exiting at non-perpendicular angles miss content provision
Solution Approach 1:
The patent changes the angle threshold parameter based on area characteristics and GPS accuracy rather than using a fixed strict threshold. This allows the system to accommodate various entry angles while maintaining reliable detection, thereby improving content delivery coverage without sacrificing detection precision.
Solution Approach 2:
The system applies different angle thresholds to different areas based on their specific characteristics. By customizing thresholds for each area rather than using a universal strict threshold, the system improves content delivery coverage for diverse entry scenarios while maintaining appropriate detection precision for each location.

AI summary
It is possible to appropriately provide information and services to a user who enters or exits a geofence. An information providing device includes a storage unit for storing area designation information for designating an area set on a route to a target, an angle threshold value, and content information about the target in association with each other, a position information acquisition unit for acquiring position information about a user terminal possessed by a user, a movement angle specifying unit configured to specify a movement angle indicating an angle at which the user enters or exits the area, by using the position information about the user terminal, an adjustment unit for adjusting the angle threshold value when a predetermined condition is satisfied, and a provision control unit for controlling provision of content information based on a result of comparison between the specified movement angle with the adjusted angle threshold value.
