Smart Room Design for Dementia Nursing Home Based on Kano-AHP-QFD Integrated Methodology

Area of Science:

• Gerontology
• Human-Computer Interaction
• Healthcare Design

Background:

• Growing demand for dementia-friendly environments.
• Existing smart room designs lack systematic user-need translation.
• Need for optimized smart living rooms in nursing homes.

Purpose of the Study:

• Propose an integrated Kano Model, Analytic Hierarchy Process, and Quality Function Deployment (Kano-AHP-QFD) framework.
• Optimize smart living room design for dementia patients.
• Enhance quality of life for elderly individuals with dementia.

Main Methods:

• Literature reviews and user interviews to identify 22 user requirements.
• Kano model for requirement categorization.
• Analytic Hierarchy Process (AHP) for requirement prioritization (behavior recognition as top priority).
• Quality Function Deployment (QFD) to translate requirements into design functions.

Main Results:

• The Kano-AHP-QFD framework provides a structured, data-driven approach.
• Behavior recognition identified as the highest priority requirement.
• Optimized smart living room designs significantly improved user satisfaction scores from 61.655 to 80.663.

Conclusions:

• The proposed framework enhances scientific rigor and practicality in smart room design.
• Offers valuable insights for designers, care providers, and policymakers.
• Applicable to various cognitive impairment care settings and special user groups.
