Priority Analysis of Wandering Alarm Device Functions for Elderly Users Based on the KANO-QFD Model with Machine Learning Algorithm
This study addresses the critical need for improving anti-wandering devices for the elderly by integrating the KANO and QFD models with machine learning. It identifies core, expected, and attractive functionalities based on a large-scale survey (506 samples), overcoming limitations of traditional surveys and technology-driven innovations. The machine learning algorithm significantly reduces false alarms (from 30.56% to 10.02%) and improves classification accuracy (from 61.76% to 67.64%), leading to more precise, user-centric device development. This framework shifts product development from 'technology stacking' to 'precision services,' ensuring devices respect dignity and enhance safety in an aging society.

Enterprise Process Flow
Performance Comparison: ML vs. Traditional
| Metric | Traditional Method | Machine Learning Algorithm |
|---|---|---|
| Accuracy (%) | 61.76 | 67.64 |
| Precision (%) | 61.05 | 67.65 |
| Recall (%) | 82.25 | 95.97 |
| F1-Score (%) | 74.36 | 80.70 |
| False Alarm Rate (%) | 30.56 | 10.02 |
Core Functional Requirements Identified
Problem: Traditional anti-wandering products suffer from homogeneity and lack of user-centric design, failing to meet the true needs of elderly users.
Solution: Through KANO-QFD, three core requirements were identified: real-time positioning (error <50m), one-touch SOS emergency calls, and waterproof/dustproof design. Other attractive demands include health monitoring and emotional interaction. Functions causing privacy intrusion or frequent false alarms were identified for removal.
Impact: This approach leads to 'precision services' by optimizing functionalities based on user priority, reducing unnecessary features, and enhancing user satisfaction and safety for elderly individuals.
