Interest Degree Measurement via Camera-Based User Behavior Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interest degree analysis systems cannot measure interest for users without registered mobile equipment, limiting their ability to gather data on users who do not possess such equipment.
Innovation Solution
An interest degree measurement system that uses cameras to capture images of users and determine their location and behavior, allowing for the calculation of interest levels based on area attributes and behavior, even for users without registered mobile equipment, and includes a simulation system to model changes in interest information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If mobile equipment such as information terminals is used to acquire user movement trajectory, then interest degree information can be obtained for users with registered equipment, but information cannot be acquired for users who do not possess registered mobile equipment
Solution Approach 1:
The patent introduces cameras as an intermediary device to capture user images and behavior, replacing the direct reliance on mobile equipment. The camera system serves as a mediator that can observe and record user movements and interests without requiring users to have or use registered mobile devices, thus expanding measurement coverage to all users in the space.
2Adaptability or versatility
If camera-based user specification and behavior tracking is implemented, then interest data can be collected for all users regardless of equipment registration, but system complexity increases
Solution Approach 1:
The patent makes the camera system perform multiple functions: user specification (identification), behavior information acquisition (movement tracking), and interest degree calculation. By consolidating these functions into a single camera-based system rather than requiring separate mobile equipment and processing systems, the overall system complexity is managed while achieving universal user coverage.
3Loss of information
If behavior information is acquired through image capture and analysis, then interest patterns can be analyzed for unregistered users, but processing requirements and computational load increase
Solution Approach 1:
The patent extracts only the essential behavior information needed for interest degree calculation from the captured images, such as movement trajectories and time spent in areas, rather than processing and storing all image data. This extraction approach reduces computational load and power requirements while maintaining complete user behavior data for analysis.

AI summary
In an interest degree measurement system included in a simulation system, a behavior information acquisition unit acquires behavior information on an arrival floor of a user on the basis of an image or images captured by a camera. An interest information acquisition unit acquires interest information representing degrees of interest of users for each attribute on a basis of arrangement and attributes of areas on the arrival floor and the behavior information. An interest information storage unit stores the interest information for each user, including information on a time point and a location. A visualization processing unit generates an interest degree map by visualizing distribution of degrees of interest of users of a building using the information stored in the interest information storage unit.
