| 14:30-14:50 | A Co-Design Exploration of Screen Design Transitions | Young children’s technology usage is on the rise and transitioning from on screen to off screen can often be difficult for both parents and children. The aim of this study is to explore whether older children can assist in the design of these transitions with younger users in mind. 75 children, aged 9 - 11, participated in a co-design session where they were required to transition designs for children aged 3 - 5 years. To explore different transitioning solutions, the children were split in three conditions (in device, in app, and external transitions). Our paper offers insights into the way children can design for others in relation to screen time ending, we critique different scaffolding methods that were used and offer advice for others doing similar work in this regard, and we suggest some design ideas for further exploration. | Megan Baxter, Matthew Horton and Janet Read | Research |
| 14:50-15:10 | Deletion Considered Harmful | In a world of information overload, understanding how we can most effectively manage information is crucial to success. We set out to understand how people view deletion, the removal of material no longer needed: does it help by reducing clutter and improving the signal to noise ratio, or does the effort required to decide to delete something make it not worthwhile? How does deletion relate to other strategies like filing; do people who spend extensive time in filing also prune their materials too? We studied the behaviour of 51 knowledge workers though a series of questionnaires and interviews to evaluate a range of tactics they used aimed at organizing, filing, and retrieving digital resources. Our study reveals that deletion is consistently under-adopted compared to other tactics such as Filing, Coverage, Ontology, and Timeliness. Moreover, the empirical data indicate that deletion is actually detrimental to retrieval success and satisfaction. In this paper, we examine the practice of deletion, review the related literature, and present detailed statistical results and clustering outcomes that underscore its adverse effects. | Paul Englefield and Russell Beale | Research |
| 15:10-15:30 | The METUX Matrix - A Design Framework for Human-Centred AI | Psychology research has shown that positive user experience is contingent on the fulfilment of three basic psychological needs (Autonomy, Competence and Relatedness). The model for “Motivation Engagement and Thriving in User Experience” (METUX) has provided tools for designing to support these needs across 6 different spheres of technology experience, but the process of addressing needs in the AI context remains challenging. As such, in this paper we present a tool designed to scaffold such a process. We introduce the METUX Matrix, a framework combining the METUX model and insights from multiple literatures to effectively anchor HCI for AI in the basic psychological needs at the heart of human experience. We draw on approaches from literature in psychology and philosophy and explore how the model can be used as part of user research, ethical enquiry, or foresight for AI systems. We do so through three case studies in three critical areas of AI research: 1. Social AI, 2. AI for health, and 3. AI for digital immortality. | Dorian Peters and Tomasz Hollanek | Research |
| 15:30-15:50 | Mindful Eating Practice and its Challenges: Insights from Expert Practitioners | The exploration of mindfulness technologies and human-food interaction has received increased HCI interest, albeit limited research has explored the intersection of these separate areas. To address this gap, we interviewed 21 mindful eating expert practitioners, including nutritionists, dietitians, psychologists, or mindfulness coaches, to understand their mindful eating practices and the feasibility of technologies to support them. Findings indicate that mindful eating practitioners use mindful eating, mindfulness, and mental health interventions for their four client groups: those living with eating disorders, including mental health conditions, non-clinical conditions, and those interested in improving overall wellbeing. Findings also highlight the challenges of mindful eating practice, and we concluded with four design implications for addressing them. | Lala Guluzade and Corina Sas | Research |
