The finding or development

Participants rated a Persian-language pregnancy app positively and valued its structured guidance. Some wanted broader nutrition and medication information. The pilot did not measure physical-activity changes or clinical outcomes.

What supports it

Peer-reviewed accepted article: one-month Android pilot; 16 participants recruited, 13 completed UEQ and interviews.

Reviewed: Publisher abstract, publication metadata and declarations reviewed 1 November 2026. Abstract-only review; PDF and supplement not reviewed.

Why it matters for design

Shows why favourable experience ratings and perceived benefits should be separated from evidence that a service improves health.

The finding or development

Caregivers and designers valued the materials but requested richer cultural context, clinical histories and calming strategies to inform personalised robot interactions.

What supports it

Peer-reviewed mixed-methods study: 15 stakeholders rated composite personas and activity maps, then discussed improvements; March–April 2025.

Reviewed: Publisher abstract, methods, discussion and limitations reviewed 29 October. Appendices and underlying data not reviewed.

Why it matters for design

A practical example of evaluating design artefacts with stakeholders before using them to guide development.

The finding or development

Models retaining more lower-rated project records generally predicted the study’s satisfaction score better than models trained on smaller, cleaner subsets. Filtering data can discard useful variation as well as errors.

What supports it

Peer-reviewed computational comparison: 134 projects, 60 data variants and 12 predictive models, with repeated nested cross-validation.

Reviewed: Publisher abstract, dataset preparation, evaluation methods, findings and validity discussion; code and supplementary results not audited.

Why it matters for design

A methods reading for testing data-exclusion rules rather than assuming stricter filtering always improves prediction. It does not justify accepting weak evidence in a literature review.

The finding or development

The proposed transfer-bed design scored higher than an existing bed in the authors’ expert evaluation. The study describes a route from stakeholder requirements to product specifications.

What supports it

Peer-reviewed accepted journal article published online ahead of its final version. Journey mapping and interviews informed requirements; Kano, AHP and QFD supported prioritisation and translation into technical characteristics. An expert panel compared designs.

Reviewed: Abstract, publication metadata and ethics statement only; full methods, results and supplements not reviewed.

Why it matters for design

Compare how each prioritisation step preserves or changes user needs. This is an editorial reading prompt, not validation of the combined method.

The finding or development

Simplified designs helped basic use, but some technically confident older participants described feeling restricted by fewer possibilities. Their accounts challenge treating age as a reliable shorthand for digital needs.

What supports it

Peer-reviewed qualitative study: one focus group with 12 co-design participants aged 60–81; thematic analysis.

Reviewed: University-hosted abstract and publication metadata reviewed 29 October. Publisher full text unavailable; abstract-only review.

Why it matters for design

Consider functional needs and digital skills separately when recruiting participants and deciding which controls to simplify.

The finding or development

The tested models scored below people on average and made reliably different patterns of errors. A good overall score alone therefore does not establish that a model interprets charts as people do.

What supports it

Peer-reviewed early publication comparing eight vision-language models with human responses across six visualisation assessments.

Reviewed: Publisher abstract and publication metadata only; methods, model versions and participant sampling not reviewed.

Why it matters for design

For designers evaluating dashboards or AI chart assistants, compare specific misunderstandings as well as accuracy. This is an editorial implication, not a tested design intervention.

The finding or development

Participants described avoiding devices, changing routines to prevent alerts, or acting to reassure caregivers. Monitoring intended to support independence could also constrain everyday choices.

What supports it

Qualitative longitudinal journal study: 21 older adults followed for over a year, with four interview phases.

Reviewed: Abstract and publication metadata on PubMed and indexed publisher record; full text could not be retrieved.

Why it matters for design

Ask whose needs an alert serves and whether residents can challenge or adjust monitoring. These are editorial design questions, not tested remedies.

The finding or development

WCAG-EM 2.0 sets out a process for defining scope, sampling, testing and reporting accessibility conformance across digital products, extending beyond websites.

What supports it

W3C Group Note · evaluation methodology

Reviewed: Published methodology, scope and status

Why it matters for design

A practical structure for documenting an accessibility evaluation and explaining the boundaries of its findings.

The finding or development

No participant completed every navigation task. Terminology and grouping findings informed a proposed library navigation redesign organised around everyday functions. Institutional approval indicated feasibility, not demonstrated usability improvement.

What supports it

Peer-reviewed mixed-methods case: access logs, usability testing (24 students), terminology questionnaire (58) and card sorting (20).

Reviewed: Publisher methods, findings, redesign proposal and limitations reviewed 31 October 2026; raw data and complete task protocol not reviewed.

Why it matters for design

A practical example of connecting several research methods to specific navigation decisions in an educational service.

The finding or development

The groups found similar totals but only 15 shared problems. Domain-specific heuristics highlighted more severe issues; Nielsen’s elicited more fine-grained findings. Interview feedback prompted clearer terminology and distinctions between heuristics.

What supports it

Journal research: expert interviews refined ten heuristics; two groups of six evaluators compared them with Nielsen’s on a social-pass Figma prototype.

Reviewed: Publisher abstract, evaluation methods, comparative results and limitations rechecked 31 October 2026; linked prototype not tested.

Why it matters for design

A published practice case linking prior findings, refinement and evaluation across an entire identity journey. Consider combining general and domain-specific checks; this is an editorial application.

The finding or development

This practitioner article turns research on reactions to AI disclosure into questions about policy, audiences, context, expectations and the extent of AI involvement.

What supports it

Practitioner synthesis of cited research

Reviewed: Article and its discussion of supporting studies

Why it matters for design

A starting point for designing and testing clear disclosures in AI-enabled products, rather than assuming that one label works for every audience.
