Poorly designed personas risk reinforcing stereotypes, marginalizing certain groups, and embedding biases into the design process. Using a mixed-method approach – combining direct inquiries with four LLMs and participatory workshops – we analyze gender bias in synthetic personas. Drawing from feminist theory, Human–Computer Interaction (HCI), and Participatory Design (PD), both societal, normative, and representational biases were identified. As a result of this, we argue that synthetic personas should not be used as direct stand-ins for real users but instead reframed as objects of critical inquiry. They can serve as provocations—tools that challenge assumptions and expose biases in LLM-generated outputs. Furthermore, this study underscores the need to move beyond exclusively expert-driven evaluations by incorporating user perspectives directly. By doing so, the evaluation process becomes richer, more representative, and better equipped to identify biases that might otherwise be overlooked.</div></div>","PeriodicalId":54955,"journal":{"name":"International Journal of Human-Computer Studies","volume":"205 ","pages":"Article 103651"},"PeriodicalIF":5.1,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145268359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different important findings that might drive the interaction design with CCTs emerged. For example, developers expressed diverse preferences on when and how code suggestions should be triggered (proactive, manual, hybrid), where and how they are displayed (inline, sidebar, popup, chatbot), as well as the level of detail. It also emerged that developers need to be supported by customization of activation timing, display modality, suggestion granularity, and explanation content, to better fit the CCT to their preferences.

Through qualitative interviews, we examined designers’ perspectives on ethics and ethics in the design process, the challenges they face, and the strategies they apply in practice. We found that designers across contexts struggle to define ethics and feel unprepared to address it. They discuss ethics in relation to design practice, and despite shared concerns, our findings show differences among work contexts. Participants are a central concern, with non-corporate designers adopting more formal approaches and deeper participant engagement. Corporate designers take more practical approaches, aligning ethics with company goals. Interviewees described strategies to address ethical challenges, offering insights into how ethics is applied in practice, where applied research designers reflect elements of both academic and corporate settings, combining strategies from each. Our findings also highlight a mismatch between formal ethical approval processes and the evolving nature of design work, where they fall short of supporting ongoing ethical reflection.

In this study, occupational therapists and computer scientists collaborate to develop a recommendation system designed to assist in configuring a smart assistive technology that helps people having sustained a traumatic brain injury cook safely. The relevance of the recommendations made by this case-based recommendation system was first evaluated by comparing the recommended assistant options with the selections of an expert occupational therapist. Then, we questioned the final users, i.e. occupational therapists, about the usefulness of such a system. This first prototype demonstrated promising results, with about 80% correct recommendations for selection (with an average percentage ranging from 77.0% to 86.2% depending on the threshold set for recommended functionalities, using a database of 16 cases). Additionally, the system was found to be robust against an unbalanced database and has been estimated as useful and relevant by end-users, who remain the final decision-makers.

However, the effectiveness of these textual explanations is often compromised by suboptimal presentation within RecSys user interfaces (UIs), leading to reduced user engagement and comprehension. This issue is particularly relevant given the recent emergence of large language models (LLMs) for generating RecSys explanations.

Based on a two-phase methodology combining qualitative user studies and quantitative evaluations, f-RecX maps four input dimensions (Explanation Style, Goals, Domain Dynamics, and Recommender Systems Technique) to an output dimension focused on visual representation. The framework aims to enhance the ’consumability’ of textual explanations by making them easier to locate and comprehend, and more valuable for non-expert users.
