Location-Aware Support System for Affected-Area Assistance Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assistance systems burden attention-requiring individuals with operations like selecting destinations or presenting non-contact media, leading to inefficient assistance unless information is output at appropriate locations corresponding to their actual location.
Innovation Solution
An assistance system with a location determining unit, area determining unit, and notification unit to identify the location and potential intersection of an attention-requiring person's path with nearby objects, outputting attention requests to relevant units in the affected area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If notification is issued to all passengers regardless of location, then attention-requiring persons receive assistance, but unnecessary notifications are sent to passengers not in the affected area
Solution Approach 1:
The notification system applies local quality by determining the specific affected area based on the attention-requiring person's location and flow line, then selectively notifying only passengers within that area. This ensures notifications are targeted to relevant locations rather than broadcast to all passengers, improving both reliability and accuracy.
Solution Approach 2:
The system performs preliminary action by determining the affected area in advance before issuing notifications. By calculating the intersection of flow lines and identifying the affected area beforehand, the system prepares the precise notification target, ensuring accurate and timely assistance without unnecessary notifications.
2Loss of information
If assistance system requires operations like destination selection or media presentation, then information can be obtained from the user, but the burden on attention-requiring persons increases
Solution Approach 1:
The system applies self-service by automatically determining the attention-requiring person's location and affected area without requiring any operations from the user. The system independently gathers necessary information through automated detection and calculation, eliminating the need for destination selection or media presentation by the user.
Solution Approach 2:
The system performs preliminary action by automatically obtaining and processing location information before assistance is needed. By pre-determining the affected area and preparing notifications automatically, the system eliminates the need for attention-requiring persons to perform operations during critical moments.
3Loss of time
If notification is issued before the attention-requiring person reaches the affected area, then timely assistance is provided, but notifications may be issued too early causing distraction
Solution Approach 1:
The system applies dynamics by continuously monitoring the attention-requiring person's movement along their flow line and dynamically determining when they are about to enter the affected area. This dynamic approach allows the system to issue notifications at the optimal moment - neither too early nor too late - based on real-time position tracking.
Solution Approach 2:
The system performs preliminary action by determining the affected area in advance and preparing notifications, but only issues them when the person approaches the area. This timing strategy provides timely assistance while avoiding premature notifications that would cause unnecessary distraction.

AI summary
A support system according to the present invention is provided with a whereabouts identifying unit configured to identify the position where a person needing care is present, an area identifying unit configured to identify an affected area, in which there is a possibility that the line of movement of the person needing care and the line of movement of an approaching object approaching the person needing care cross each other, and a notification unit configured to output a care request to an output unit existing in the affected area.
