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.

Key Findings
- 01The proposed method successfully incorporates qualitative features into choice models.
- 02The use of images can introduce a bias in the perceived magnitude of design 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.

Variables
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?
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.
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.
