Current UX evaluation for IoT-based Smart City applications heavily relies on subjective methods like questionnaires and interviews, with limited use of objective usage data or expert reviews. This user-centred design research insight is drawn from a 2024 study published in Academic Publication. Using Rapid systematic review with 43 studies, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Expand UX evaluation beyond questionnaires and interviews to include objective usage data and expert reviews for a more complete understanding of user experience in IoT Smart City applications.
Questionnaires Dominate IoT Smart City UX Evaluation, Neglecting Usage Data

Key Findings
- 01Questionnaire-based user testing (e.g., SUS, UEQ) and interviews are the most frequently employed methods for evaluating IoT applications.
- 02There is a notable lack of studies utilizing user testing based on automated measurements or expert-based reviews.
- 03There is a need to explore UX evaluation methods that leverage usage data and employ a combination of methods for continuous UX evaluation in IoT and Smart City environments.
Application
Design takeaway
Expand UX evaluation beyond questionnaires and interviews to include objective usage data and expert reviews for a more complete understanding of user experience in IoT Smart City applications.
How to apply
When designing an IoT-based Smart City application, plan for a UX evaluation that includes not only user surveys and interviews but also the collection and analysis of actual usage data (e.g., interaction logs, performance metrics) and potentially expert heuristic evaluations.
Project actions
- 01When evaluating your design, don't just rely on surveys. Think about how you can observe users interacting with your prototype or collect data on their usage patterns.
- 02Consider incorporating expert reviews as a complementary method to identify potential usability issues.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Provides a systematic overview of current UX evaluation practices in a relevant domain.
- +Identifies a clear gap in the research and practice regarding the use of objective data and expert reviews.
Limitations
A rapid review might miss some relevant studies. The findings are heavily weighted towards smart home applications, so they might not apply equally to all smart city domains.
Reliability & validity
The reliability of the review depends on the systematic search and inclusion criteria. Validity is supported by the synthesis of findings across multiple studies, but the 'rapid' nature might affect comprehensiveness.
Think critically
Given the prevalence of subjective evaluation methods, what are the potential biases or limitations introduced into the UX assessment of IoT-based Smart City applications, and how can these be mitigated?
Design Principles
"Employ a diverse range of evaluation methods, integrating both subjective user feedback and objective usage data, to comprehensively assess the user experience of complex interactive systems."
This reliance on subjective feedback can lead to a superficial understanding of user experience, potentially overlooking critical usability issues that arise during actual product use. Designers need to incorporate a broader range of evaluation methods to ensure robust and reliable UX insights for complex, interconnected systems.
What This Means for Your Design
When you test how people use smart city apps that connect to things (like IoT), most studies just ask them questions or interview them. They don't often look at how the app is actually being used with data or get experts to check it.
How to use in your project
- 1.Reference this study to justify the need for a comprehensive UX evaluation strategy in your design project, particularly if your project involves IoT or complex interactive systems.
- 2.Use the findings to support your choice of evaluation methods, explaining why you are including both subjective and objective measures.

Paragraph starter
This research highlights a common trend in evaluating IoT-based Smart City applications, where user experience assessment predominantly relies on subjective methods such as questionnaires and interviews, with a notable underutilization of objective usage data and expert reviews. To ensure a comprehensive understanding of user experience for complex interactive systems, it is imperative to adopt a mixed-methods approach that integrates both qualitative feedback and quantitative usage metrics, as suggested by Choma and Zaina (2024).
