Images can be used to quantify subjective qualitative attributes of public spaces within choice experiments, but careful analysis is needed to account for perceptual biases. This user-centred design research insight is drawn from a 2015 study published in Transportation research procedia. Using Sequential estimation of discrete choice and latent variable models, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When using images in design research, implement methods that account for subjective interpretation to ensure accurate data on user perceptions of qualitative attributes.

Application

Design takeaway

When using images in design research, implement methods that account for subjective interpretation to ensure accurate data on user perceptions of qualitative attributes.

How to apply

In user research for public spaces or products, use carefully selected and validated images in surveys to gauge user responses to aesthetic and experiential qualities, and analyze results with an awareness of potential perceptual biases.

Project actions

  • 01When selecting images, consider their clarity, representativeness, and potential for varied interpretations.
  • 02Be explicit about the qualitative attributes you are trying to measure with each image.

Method & Evidence

AimHow can visual representations be used to quantify subjective qualitative attributes of public spaces in design research?
MethodSequential estimation of discrete choice and latent variable models
ProcedureImages depicting public spaces were used in stated preference surveys. The method involved estimating choice models and latent variable models sequentially to quantify the relevance of qualitative attributes like beauty and safety, while also analyzing potential biases introduced by image perception.
ContextUrban design and public space planning

Variables

IVVisual representation of public space attributes (images)
DVPerceived relevance/magnitude of qualitative attributes (e.g., beauty, safety)
CVImage content, survey design, participant demographics
04

Strengths & Limitations

Strengths

  • +Provides a methodological approach to quantify subjective perceptions.
  • +Addresses the practical challenge of representing complex design scenarios visually.

Limitations

The specific images chosen might not be universally representative, and the participant pool's cultural background could influence their interpretation of the visuals.

Reliability & validity

Reliability could be assessed by re-testing participants with the same images. Validity would depend on how well the chosen images and subsequent quantitative measures truly capture the intended qualitative attributes.

Think critically

How can designers ensure that the images used in research accurately reflect the intended design qualities and minimize subjective misinterpretations?

05

Design Principles

"Quantify the qualitative: Use structured methods to translate subjective user perceptions into measurable design data."

Understanding how users qualitatively perceive design elements like beauty or safety is crucial for creating effective public spaces. This research offers a method to bridge the gap between subjective visual perception and quantitative design analysis, enabling more user-informed design decisions.

06

What This Means for Your Design

You can use pictures to ask people what they think about how beautiful or safe a public space looks, and then turn their answers into numbers. But be careful, because people might see the pictures differently than you expect, which can change the numbers.

Paragraph starter

This research by Hurtubia, Guevara, and Donoso (2015) highlights the potential of using images in stated preference surveys to quantify qualitative attributes of design, such as the perceived beauty or safety of public spaces. While effective in incorporating subjective feedback, the study also cautions that image perception can introduce biases in the magnitude of design attributes, necessitating careful analysis and validation.
