Visiting Place Identification Using Payment and Stay Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals, including GPS and PHS, struggle to accurately identify specific facilities visited by users, especially in crowded areas like shopping malls or multi-tenant buildings, due to positional errors, which hinders accurate modeling of user behavior and destination prediction.
Innovation Solution
A visited-place identification apparatus that combines position determination, behavior detection, and facility identification, using units such as payment amounts and stay times to accurately pinpoint visited facilities within a predetermined area, allowing for precise tracking and prediction of user behavior patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS positioning is used to determine user position, then positional accuracy is improved (several meters), but it still cannot pinpoint which specific facility the user is visiting in shopping malls or multi-tenant buildings
Solution Approach 1:
The patent segments the facility identification process into multiple stages: first identifying a candidate area using GPS positioning, then narrowing down to specific facilities within that area using behavior detection. This segmentation allows the system to handle the complexity of facility identification in large complexes by breaking it into manageable steps.
Solution Approach 2:
The patent introduces behavior detection (payment amounts, stay times) as an intermediary element that bridges the gap between GPS positioning and facility identification. These behavioral data serve as additional criteria to distinguish between multiple facilities located in the same GPS coordinates, enabling precise identification even in crowded areas.
2Device complexity
If base station positioning is used to determine user position, then device complexity is reduced, but positional accuracy deteriorates (several dozen meters error)
Solution Approach 1:
The patent merges two positioning approaches: base station positioning for broad area identification and GPS for precise location within that area. By combining these methods, the system achieves both the simplicity of base station positioning and the accuracy of GPS, resolving the contradiction between device complexity and measurement precision.
3Ease of operation
If only position information is used to identify visited places, then the system is simple to operate, but it cannot accurately model user behavior patterns
Solution Approach 1:
The patent performs preliminary behavior detection (payment amounts, stay times) alongside position determination. By collecting these additional data points in advance, the system builds a comprehensive user profile that enables accurate behavior pattern modeling without complicating the user interface or operation.

AI summary
A current position determination unit determines a current position of a user; a facility candidate search unit specifies, as a candidate for a visited place, a facility that is located within a predetermined area including the current position determined by the current position determination unit; an electronic money unit and a payment amount calculation unit detect a payment amount of the user; and a most-likely visited facility identification unit identifies a most-likely visited place by selecting from a plurality of facilities a facility corresponding to the payment amount detected by the electronic money unit and the payment amount calculation unit, when the plurality of facilities are specified by the facility candidate search unit.
