Understanding How Mobile Interactions Shape Grasp and Contact Patterns Beyond the Touchscreen

The way users hold a smartphone depends on the interaction task, yet little is known about the fingers' engagement with the device's surfaces beyond the touchscreen. Such an understanding not only opens up opportunities for novel on- and off-screen interactions, but also the device’s possible physical affordances. We…

Take the Power Back: Screen-Based Personal Moderation Against Hate Speech on Instagram

Hate speech remains a pressing challenge on social media, where platform moderation often fails to protect targeted users. Personal moderation tools that let users decide how content is filtered can address some of these shortcomings. However, it remains an open question on which screens (e.g., the comments, the reels…

Capturing Team Cognition: A Multimodal Dataset for Adaptive Collaborative Interfaces

We introduce a multimodal dataset and experimental setup designed to support the development of adaptive collaborative systems. Data were collected from distributed teams working simultaneously across two continents, demonstrating the feasibility of sensing team cognition in geographically dispersed settings. The data…

Rest Assured: Detecting Mental Fatigue and Recovery with EEG Headphones

Mental fatigue, a common consequence of cognitively demanding work, impairs concentration and well-being, posing long-term health risks. Distinct from drowsiness, mental fatigue is reliably measured with EEG, yet conventional setups remain too cumbersome for everyday use. To overcome this barrier, this study investiga…

Satisficing vs. Maximizing in Prompt Writing: Trait and Task Effects in Human–AI Interaction

Generative AI systems are increasingly used for cognitively demanding tasks, yet little is known about how psychological factors shape user prompting behavior. This study investigates the role of individual satisficing tendencies in maximizing behavior when selecting prompt strategies across different task domains. In…

Supporting Communication and Well-being with a Multi-Stakeholder Mobile App: Lessons Learned from A Field Study with ADHD Children and their Caregivers

Children with attention deficit hyperactivity disorder (ADHD) and their caregivers face daily challenges which can adversely affect their well-being, especially regarding communication within their care ecosystems, comprising family, friends, educators, and therapists. To foster communication among children and their…

Mind Games! Exploring the Impact of Dark Patterns in Mixed Reality Scenarios

Mixed Reality (MR) integrates virtual objects with the real world, offering potential but raising concerns about misuse through dark patterns. This study explored the effects of four dark patterns, adapted from prior research, and applied to MR across three targets: places, products, and people. In a two-factorial wit…

Give and Take: Perceptions of a Conversational Coach Agent in Fitness Trackers

While Personal Informatics (PI) tools utilise data visualisations to communicate behaviour, users often struggle to make sense of their data and translate it to actionable insights. Conversational Agents (CAs) offer potential for improved access to PI data, yet their role in PI tools remains under-explored. We conduct…

Crossing the Line? The Paradox of Human-Like Design in Conversational Agents

Since the early development of conversational agents (CAs), human-likeness has been a central design focus. Numerous studies have highlighted the benefits of more human-like CAs, including user experience, engagement, and trust improvements. As a result, researchers have proposed guidelines for designing CAs that clos…

Beyond the Illusion: LLMs and the Case for Pragmatic Cues in Conversation

Conversational agents are becoming increasingly adept at interacting with humans in a very natural manner. They incorporate subtle linguistic and paralinguistic cues: changes in tone and style, emotional expressions, or fillers like `mm-hm'. In human communication, such cues serve pragmatic functions that support mutu…
