Notifications are an indispensable feature of mobile devices, but their delivery can interrupt and distract users. Prior work has examined interventions, such as deferring notification delivery to opportune moments, but has not systematically studied how ...

Managing attention, progressing towards goals, and monitoring behaviors are elements of self-regulation (SR). SR applications based on contemplative practices such as breath counting have demonstrated gains in field studies but have failed to engage youth ...

This article presents an annotated portfolio of projects that seek to understand and communicate the social and societal implications of blockchains, DLTs and smart contracts. These complex technologies rely on human and technical factors to deliver ...

User trust plays a key role in determining whether autonomous computer applications are relied upon. It will play a key role in the acceptance of emerging AI applications such as optimisation. Two important factors known to affect trust are system ...

Two-factor authentication (2FA) is a recommended or imposed authentication mechanism for valuable online assets. However, 2FA mechanisms usually exhibit user experience issues that create user friction and even lead to poor acceptance, hampering the wider ...

The COVID-19 pandemic disrupted processes interaction designers took for granted, challenging some of our most commonplace design practices. Participatory and situated approaches have been impacted the most: where we engaged stakeholders in-person and in-...

Previous user experience research emphasizes meaning in interaction design beyond conventional interactive gestures. However, existing exemplars that successfully reify abstract meanings through interactions are usually case-specific, and it is currently ...

HCI researchers increasingly involve plants in their interaction design research, such as using plants as novel interfaces or sensors. While research involving other living entities, namely humans and animals is regulated, there exists no guidance for ...

This article investigates new relations with things that are expansive and inclusive of the pluralities and differences within our entanglements with technologies. We do this by extending our commitments to the methodological approaches of material ...

Technology “demos” have become a staple in technology design practice, especially for showcasing prototypes or systems. However, demonstrations are also commonplace and multifaceted phenomena in everyday life, and thus have found their way into empirical ...

Telemedicine systems that involve the use of video conferencing technologies have been available for more than three decades. Yet, they have primarily been used for specialist appointments or within health care facilities. We are now seeing a shift with ...

Technologies can support the well-being of people living with dementia in residential care by fostering meaningful interactions through multimodal and playful features. This article presents the evaluation of A Better Visit, an app that aims at engaging ...
