Key Findings

  • 01Kansei factors influencing elderly users' perception of vehicle form were identified and clustered.
  • 02Key design features impacting elderly-oriented satisfaction were pinpointed through attribute reduction.
  • 03A predictive model was established to map design features to optimal emotional responses for elderly users.
  • 04Specific features like 'Hub6', 'Headlight9', 'Car side view2', 'Rearview mirror9', and 'Front door10' were identified as crucial for eliciting optimal emotions.

Application

Design takeaway

Prioritize specific, emotionally resonant design features identified through user research when designing vehicles for the elderly, rather than relying solely on general aesthetic trends.

How to apply

Conduct user research to identify key Kansei factors for your target demographic, deconstruct product aesthetics into measurable features, and use data analysis to determine which features most strongly influence desired emotional responses.

Project actions

  • 01Clearly define the target user group and their specific needs and emotional drivers.
  • 02Use a structured approach to deconstruct the product's form and identify measurable design attributes.
  • 03Employ appropriate data analysis techniques to correlate design features with user responses.

Method & Evidence

AimHow can Kansei engineering principles and data-driven modeling be used to optimize the form design of low-speed new energy vehicles to align with the emotional and perceptual needs of elderly users?
MethodMixed-methods research combining qualitative analysis (Kansei factor identification) and quantitative modeling (rough set theory, support vector regression).
ProcedureThe study involved identifying Kansei factors relevant to elderly users, deconstructing vehicle appearances into key design features, using rough set theory to reduce these features to those most impactful on user satisfaction, and employing support vector regression to build a predictive model linking design features to optimal emotional responses.
ContextAutomotive design, specifically low-speed new energy vehicles for the elderly.

Strengths & Limitations

Strengths

  • +Systematic approach to linking user emotions with design features.
  • +Utilizes advanced data analysis techniques for predictive modeling.

Limitations

The sample size of participants may limit the generalizability of findings. The specific context of low-speed NEVs might not apply to broader automotive design challenges.

Reliability & validity

Reliability could be enhanced by using standardized questionnaires and ensuring consistent presentation of design stimuli. Validity is supported by the use of established Kansei engineering principles and statistical modeling techniques to link subjective user responses to objective design features.

Think critically

To what extent can the emotional responses identified for one specific product category (low-speed NEVs) be generalized to other product types or user groups, and what are the potential pitfalls of over-reliance on quantitative modeling for subjective emotional design?

05

Design Principles

"Design for emotional resonance by systematically linking user-perceived attributes to desired affective outcomes."

Understanding the emotional drivers behind user preferences is crucial for designing products that resonate with target demographics. This approach allows for data-driven design decisions that can enhance user satisfaction and market appeal, particularly for aging populations.

06

What This Means for Your Design

This study shows how designers can figure out what makes older people feel good about the look of a small electric car by asking them about their feelings and then using math to find the best design parts.

How to use in your project

  • 1.Use the Kansei engineering framework to guide your user research and identify emotional design targets.
  • 2.Apply morphological analysis to break down your design into key features for systematic evaluation.
  • 3.Consider using statistical methods to analyze the relationship between design choices and user satisfaction.
