Short answer

When designing vehicle interiors, prioritize understanding and translating users' emotional responses into design features, using structured methods like Kansei engineering and QFD to ensure these emotional needs are met in a systematic and adaptable way.

Field: Human Factors
Source: PLoS ONE (2024)
Method: Mixed-methods research combining qualitative analysis of user emotional vocabulary with quantitative modeling using Fuzzy Analytic Hierarchy Process (FAHP) and Fuzzy Quality Function Deployment (QFD).
Evidence: Strong effect

By integrating Kansei engineering with fuzzy Quality Function Deployment (QFD), designers can systematically translate subjective user emotional preferences into tangible design specifications for adaptable automotive interiors. This human factors research insight is drawn from a 2024 study published in PLoS ONE. Using Mixed-methods research combining qualitative analysis of user emotional vocabulary with quantitative modeling using fuzzy analytic hierarchy process (fahp) and fuzzy quality function deployment (qfd)., researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing vehicle interiors, prioritize understanding and translating users' emotional responses into design features, using structured methods like Kansei engineering and QFD to ensure these emotional needs are met in a systematic and adaptable way.

03The approach offers valuable suggestions for the future development of automotive interior spaces.

Application

Design takeaway

How to apply

Use Kansei word association exercises with target users, then employ FAHP to prioritize these emotional drivers, and finally, use a QFD matrix to translate these priorities into specific design features for interior elements.

Project actions

01When researching user needs, don't just ask what people want, ask how they *feel* about different design elements.
02Consider how your design could be adapted or changed by the user over time to maintain relevance and satisfaction.

Method & Evidence

AimHow can Kansei engineering and fuzzy QFD be integrated to systematically design growable automotive interiors that address users' emotional needs and preferences?

MethodMixed-methods research combining qualitative analysis of user emotional vocabulary with quantitative modeling using Fuzzy Analytic Hierarchy Process (FAHP) and Fuzzy Quality Function Deployment (QFD).

ProcedureThe study analyzed user emotional needs (SET factors) using FAHP, extracted Kansei words from interior space samples, performed factor analysis on these words, and then constructed a fuzzy QFD model to derive design weights for guiding the development of dynamic automotive interaction scenarios.

ContextAutomotive interior design, smart vehicles, user personalization.

Variables

IV["User emotional needs/preferences (e.g., SET factors, Kansei words)","Design attributes of the vehicle interior"]

DV["Design weights/priorities for interior features","Effectiveness of the growable/adaptable interior design","User satisfaction with the personalized interior"]

CV["Specific vehicle model/platform","User demographic characteristics (if controlled)","Environmental conditions during user testing"]

Strengths & Limitations

Strengths

+Systematic approach to capturing subjective user emotions.
+Integration of multiple advanced analytical techniques (FAHP, FQFD, Kansei Engineering).
+Addresses the growing trend of personalization in product design.

Limitations

It can be challenging to gather a diverse enough sample of emotional vocabulary, and the complexity of fuzzy logic might be difficult to fully implement without specialized software.

Reliability & validity

The use of established methods like FAHP and QFD lends validity to the structured approach. Reliability would depend on the consistency of user responses and the clear definition of Kansei words and their associated factors.

Think critically

To what extent can emotional needs be fully captured and translated through quantitative methods, and what are the risks of oversimplification or misinterpretation?

Design Principles

"Translate subjective user emotions into objective design parameters through structured analytical and deployment frameworks."

As vehicles evolve into personalized spaces, understanding and responding to users' emotional and aesthetic desires is crucial for market success and user satisfaction. This approach provides a structured method to bridge the gap between abstract emotional needs and concrete design decisions, leading to more desirable and adaptable product offerings.

What This Means for Your Design

This study shows how car designers can figure out what feelings people want in their car interiors and then use special tools (like FAHP and QFD) to design cars that can change and adapt to those feelings.

How to use in your project

1.Use the concept of Kansei words to explore user emotional responses to existing products or design concepts.
2.Adapt the FAHP or QFD methodology to prioritize user needs or design attributes in your own design project.
