In-Vehicle Device for Automated Subject Behavior Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for monitoring the safety and health conditions of individuals, such as elderly persons, require frequent visits from salespersons, which is burdensome and inefficient.
Innovation Solution
An in-vehicle device equipped with an image capturing unit, control unit, and storage unit that captures images, detects subjects, recognizes their behaviors, and stores this information for association, allowing for remote monitoring without undue burden on the target.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the salesperson visits the user's house frequently to check on the target, then the reliability of health condition monitoring is improved, but the ease of operation deteriorates due to burden on the salesperson
Solution Approach 1:
The system enables automatic self-monitoring of health conditions through image capture and behavior recognition, eliminating the need for salesperson visits. The device autonomously detects subjects, recognizes behaviors, and transmits information without human intervention, resolving the contradiction between monitoring reliability and operational ease.
Solution Approach 2:
The patent replaces the mechanical system of physical visits by salespersons with an automated image-based detection system. The image capturing unit, control unit, and storage unit work together to substitute manual inspection with automated behavior recognition, improving both reliability and ease of operation.
2Reliability
If the target sends reply messages to confirm safety, then the reliability of health condition monitoring is improved, but the ease of operation deteriorates due to burden on the target
Solution Approach 1:
The system performs self-monitoring automatically without requiring target participation. The image capturing unit continuously captures images, the control unit detects subjects and recognizes behaviors, and the storage unit saves information autonomously, eliminating the burden of sending reply messages while maintaining monitoring reliability.
Solution Approach 2:
The patent introduces an intermediary system (image capturing unit, control unit, storage unit) that mediates between the target and the monitoring process. This intermediary automatically handles all monitoring tasks without requiring direct target involvement, resolving the contradiction between reliability and ease of operation.
3Reliability
If the salesperson visits the user's house when there is no reply, then the reliability of health condition monitoring is improved, but the productivity deteriorates due to frequent visits being burdensome
Solution Approach 1:
The system enables continuous automated monitoring through uninterrupted image capture and behavior recognition. The image capturing unit operates continuously, the control unit processes images in real-time, and the storage unit maintains records without interruption, providing continuous monitoring without the productivity loss associated with frequent visits.
Solution Approach 2:
The patent replaces the mechanical visit-based monitoring system with an automated image processing system that operates continuously without human intervention. This substitution eliminates the productivity burden of frequent visits while maintaining continuous monitoring reliability.

AI summary
An in-vehicle device includes a control unit, a storage unit configured to store features of each subject that is a person, and an image capturing unit. The control unit obtains an image captured by the image capturing unit, detects a subject in the obtained image based on the features stored in the storage unit, recognizes a behavior of the detected subject from the obtained image, and stores the detected subject and the recognized behavior in association with each other.
