“It’s Just a Wild, Wild West”: Harnessing Public Procurement as an AI Governance Mechanism

Public sector AI has the potential to harm citizens, with risks increasing as its use expands. Recent work positions public procurement as a way to shape public sector AI in line with public interests, using the state’s purchasing power to influence which AI systems are procured and under what conditions. This paper e…

When Play Hurts: Understanding Common Barriers in Movement-Based Games

Exergames promise enjoyable physical activity through gameplay, yet players often face barriers that undermine engagement, safety, and retention. To date, knowledge about which barriers are encountered by end-users of commercial exergames and which mitigation strategies are used is limited. To address this gap, we con…

Determining Perception Thresholds for Real and Virtual Inclinations While Cycling in Virtual Reality

In virtual reality (VR) experiences, mismatches between reality and virtuality are usually undesirable, as they can disrupt immersion and induce cybersickness. However, when carefully controlled, they may expand the design space of VR. This research investigates perceptual detection thresholds for mismatches between r…

Show Me How to Play: Exploring Self-Modeling for Onboarding in Virtual Reality Exergames

Exergames combine motivating game elements with bodily movement to encourage physical activity. However, onboarding players to perform correct movements remains a challenge, especially in virtual reality (VR) environments where safety and performance are critical. Drawing inspiration from sports training and learning…

Certified But Imperfect: Investigating The Role of AI Certifications And System Performance on Trust in And Reliance on AI Systems

While regulatory frameworks call for the implementation of AI certifications, empirical knowledge about how such certifications affect interactions is still scarce. In this work, we examined how AI certifications affect users' trust and reliance. In addition, we examined whether certifications elevate user expectation…

The Limits of Stakeholder Participation in Safety-Critical Contexts: Lessons from Air Traffic Control

Calls for participatory AI development often assume that stakeholders can and should substantially shape a system's design. However, this agency may be constrained by competing demands, e.g. those safety-related. We explore this tension through a case study in Air Traffic Control (ATC) system development. Interviews w…

Certified AI System = Trustworthy? Exploring Expert and Lay User Perceptions and Needs Regarding AI Certification

AI certification has emerged as a promising mechanism to enhance transparency, accountability, and public trust. However, end-user perspectives remain largely unexplored. This study investigates two groups with differing AI expertise. Through qualitative interviews with 30 participants (15 experts, 15 lay users), we e…

Who Controls the Conversation? User Perspectives On Generative AI (LLM) System Prompts

System prompts---instructions that shape the behaviour of generative AI systems---strongly influence system outputs and users' experiences. They define the model's guidelines, `personality', and guardrails, taking precedence over user inputs. Despite their influence, transparency is limited: system prompts are gen…

Flow on Social Media? Rarer Than You'd Think

Researchers often attribute social media’s appeal to its ability to elicit flow experiences of deep absorption and effortless engagement. Yet prolonged use has also been linked to distraction, fatigue, and lower mood. This paradox remains poorly understood, in part because prior studies rely on habitual or one-shot re…

Campus AI vs. Commercial AI: Comparing How Students and Employees Perceive their University’s LLM Chatbot vs. ChatGPT

As the use of LLM chatbots by students and researchers becomes more prevalent, universities are pressed to develop AI strategies. One strategy that many universities pursue is to customize pre-trained LLM-as-a-service (LLMaaS) chatbots. While most studies on LLMaaS chatbots prioritize technical adaptations, these s…
