St Andrews HCI Research Group

Welcome to the website for SACHI which aims to act a focal point for human computer interaction research across the University of St Andrews and beyond.

SACHI is the St Andrews Computer Human Interaction research group (a HCI Group) based in the School of Computer Science. Members of SACHI co-supervise research students, collaborate on various projects and activities, share access to research equipment and our HCI prototyping workshop. Established in 2011, we now have a regular seminar series, social activities, summer schools and organise workshops and conferences together. Along with the above links, you can find more news about us here.

Seminar: Democratising the Design and Development of Emerging Technologies 17th March 2025


Abstract:

My research focuses on democratising the development of emerging technologies. More specifically, by establishing accessible approaches for designing and building emerging technologies such as robotics, wearables, and shape-changing interfaces. To advance the field, my research focuses not only on understanding these technologies (e.g., their design), but also how to build them (e.g., engineer them), and how to innovate with them (e.g., application). In this talk, I will go into detail about some of the projects I have worked on around this topic across the fields of HCI, Design, and Engineering.

Bio:

Dr. Aluna Everitt is a lecturer in the Department of Computer Science and Software Engineering at the University of Canterbury, New Zealand. Prior to moving to Christchurch (NZ), she was a Research Associate in the Cyber-Physical Systems group at the University of Oxford and a Junior Research Fellow at Kellogg College, University of Oxford. She was also a Senior Visiting Researcher and postdoc at the University of Bristol (BIG Lab). Dr. Everitt was awarded her PhD in Computer Science from Lancaster University, specializing in Human-Computer Interaction (HCI). As a multi-disciplinary researcher, her areas of interest and expertise lie across the fields of HCI, Design, and Engineering. She has a particular interest in conducting both quantitative and qualitative research which combines a mix of engineering fabrication approaches for iterative prototyping, together with collaborative design (co-design) to encourage users and experts from different domains to develop content and applications for the next generation of interactive hardware systems and interfaces (e.g., shape-changing displays, wearables, and robotics).

Seminar: An Upcycled IoT 12th March 2025


Abstract:

The Internet-of-Things (IoT) promises to enhance even the most mundane of objects with computational properties. Yet, IoT has largely focused on new devices, and so, has required households to replace their possessions to adopt IoT. Replacement brings disruption to the home and generates substantial waste. To address this, my research asks us to re-envision how IoT is integrated into the home and asks us to imagine, what if we could upcycle our existing possessions with IoT so that family practices are resilient to technological change? In this talk I’ll describe day to day family life, how families imagine IoT making home life better, a lightweight system to graft IoT onto existing possessions, and open problems in tangible interaction, DIY modification, and sensor uncertainty that need addressed to make an Upcycled IoT possible. Along the way, I’ll describe work my lab has been doing to make progress on these open challenges and the implications these have for making IoT both sustainable and capable of supporting resilient homes.

Bio:

Kristin Williams is an Assistant Professor of Computer Science in Emory University’s College of Arts and Sciences. Her research focuses on making programming the Internet of Things approachable to casual end user programmers. This work builds on Kristin’s longstanding interests in agency, DIY publishing, and access to information. In the past, Kristin has worked closely with community organizations to shape and evaluate assistive technologies for individuals with visual and cognitive disabilities, managed an archive of Soviet dissident literature on the political abuse of psychiatry, and created a 10+ year book project on Central Asian civil society as a Peace Corps volunteer in Kazakhstan. She has a PhD from Carnegie Mellon University’s Human Compter Interaction Institute, an MS in Human-Computer Interaction from both Carnegie Mellon University and the University of Maryland, College Park and a BA in Philosophy from Reed College. She was a 2021 EECS Rising Star, an NSF EAPSI Fellow, and an AAUW Career Development Grantee.

WikiConnect: Bridging Knowledge Gaps for a Fairer Digital Future for all


Wikipedia has become an essential pillar of global knowledge-sharing, but it is far from perfect. Gaps in coverage and skewed information disproportionately impact underrepresented communities, creating a biased view of the world. They also lay the groundwork for biased AI systems that rely on flawed data.

Come and join this webinar to hear from Abd Alsattar Ardati from University of St Andrews about the Digital Inclusion WikiConnect project that empowers participants with the skills and resources to close critical knowledge gaps, raise awareness about digital poverty, and build a more inclusive, equitable digital knowledge ecosystem.

Find out how curating accessible, high-quality content on digital inclusion, WikiConnect doesn’t just document inequalities—it actively works to reduce them, such as the role of shared knowledge in breaking down barriers to digital literacy and other examples of how small, deliberate contributions can ripple outward, driving meaningful change and empowering communities.

You can be part of this too! Come and join, and share this.

Speaker: Abd Alsattar Ardati

Excited to be speaking at this upcoming British Computer Society webinar—open to all! If you’re interested in digital inclusion, open knowledge, collaboration, or AI bias, this one’s for you. Hope to see some familiar faces there!

We need to rethink collaboration to close critical knowledge gaps on Wikipedia—gaps that don’t just limit access to information but fuel a vicious cycle of digital exclusion. AI systems trained on incomplete or biased data don’t just reflect inequalities—they amplify them [1]. As McDowell [2] puts it, ‘bias in, bias out’—a spin on ‘garbage in, garbage out’, highlighting how gaps in data can perpetuate systemic bias.

I’ll share insights from my participatory design research and explore how we can build a more inclusive, equitable digital knowledge ecosystem. I’ll also highlight how the WikiConnect project, part of The IDEA Network in Open Research at the University of St Andrews, raises awareness about digital poverty and shows how you can get involved.

Would love to hear your thoughts—let’s start the conversation! 💡
