Title: Invisible Health Clues in Everyday Handwriting

Abstract: Everyday handwriting may quietly reflect subtle changes in a person’s health. This project explores how natural writing patterns—such as stroke dynamics, pressure, and rhythm—can offer early indicators of motor or neurological conditions. Without relying on wearables or clinical tasks, the approach passively monitors handwriting during familiar, routine activities. By capturing and analyzing writing behaviour over time, it becomes possible to build personal baselines and detect meaningful deviations. This work envisions a privacy-preserving, low-effort way to integrate long-term health awareness into daily life.

Title: Privacy and Trust on the Web

Abstract: Many web users use content blockers to block ads and privacy invasive trackers from the sites they visit. Due to their increasing popularity and the nature of a web funded by ads and tracking, ad-tech firms have resorted to more and more sophisticated countermeasures to evade these blocks that have created an arms race between the blockers and trackers. Since many content blockers rely on community curated filter-lists that require laborious manual review, combined with the increasingly dynamic obfuscation techniques utilised by trackers to evade these blocks, issues surrounding the scalability of content blockers have arisen.

While many automated solutions have been proposed to assist in blocking unwanted privacy-harming functionality, there is still no comprehensive solution that tackles all privacy-invasive behaviours, avoids breaking legitimate website functionality, and is robust to evasion techniques. Existing solutions all have trade-offs but do not appear to offer the user any control over what trade-off they wish to make. This project will seek to demonstrate that it is possible to give users control over the granularity of trade-off they wish to make that will satisfy the trade-offs in a scalable and robust manner for their use case.

Title: Understanding the Planning Capabilities and Limitations of LLMs in Blocks World.

Abstract: We investigates the planning capabilities of Large Language Models (LLMs) in the symbolic Blocks World domain. While prior work has shown that LLMs often fail to generate correct or executable plans, we shift focus toward understanding the causes of plan failures and identifying the conditions under which LLMs succeed. We evaluate a range of LLMs across problems of varying difficulty and four prompt types with varying degrees of information in natural language. To support this analysis, we introduce a fine-grained failure category spanning Plan, Goal, State, and Action. The analysis deepens our understanding of LLM planning behavior and contributes an empirical framework for diagnosing failure modes, thereby informing the development of more reliable LLM-based planning systems.

Title: Context-PEFT: Efficient Cross-Domain Transfer Learning

Abstract: Parameter-Efficient Fine-Tuning (PEFT) techniques such as LoRA, BitFit and IA3 have demonstrated comparable performance to full fine-tuning of pre-trained models for specific downstream tasks, all while demanding significantly fewer trainable parameters and reduced GPU memory consumption. However, in the context of cross-domain transfer learning, the need for architectural modifications or full fine-tuning often becomes apparent. To address this we propose Context-PEFT, which learns different groups of adaptor parameters based on the current input domain. This approach enables LoRA-like weight injection without requiring additional architectural changes. Our method is evaluated on the COCO captioning task, where it outperforms full fine-tuning under similar data constraints while simultaneously offering a substantially more parameter-efficient and computationally economical solution.

Title: Methodologies for Creating Interactive and Lifelike Historical Characters Based on MetaHuman

Abstract: Virtual characters have long held promise as pedagogical tools in heritage education, particularly for creating immersive interactions with historical figures. Researchers have envisioned systems capable of emulating these figures, enabling users to engage in life-like, face-to-face dialogues over time. While technological constraints historically limited such applications, recent advancements in computational graphics and language models have now made them viable. This paper presents a framework for constructing interactive virtual character systems, outlining their core components through two critical dimensions: photorealism and interaction. The photorealism dimension leverages modern graphics tools to achieve high-fidelity visual representation, while the interaction dimension utilizes language models to enable socially believable and contextually responsive dialogue. We examine the necessity of each component and analyze available technological solutions with their respective trade-offs. Beyond the technical framework, we discuss potential future improvements and address ethical and practical concerns inherent to such systems. By synthesizing current technologies and their applicability, this work provides institutions with practical guidance for developing customized interactive systems that balance functionality with cost-efficiency.

EDI Talk: Why Do We Need Diversity in Research Software Engineering

On Thursday 22nd May the EDI committee hosted a talk on “Why Do We Need Diversity in Research Software Engineering?” by the Software Sustainability Institute Fellows Deborah Udoh (OLS) https://www.software.ac.uk/fellowship-programme/deborah-udoh and Olexandr Konovalov (St Andrews) https://www.software.ac.uk/fellowship-programme/olexandr-konovalov. On display we had a collection of posters designed by students to promote and raise awareness of EDI aspects, and celebrate cultural differences in the School and in our discipline. This was accompanied by coffee and cakes.

This talk was the story of two members of the global research software community whose paths converged thanks to the Software Sustainability Institute. One a Ukrainian mathematician and computer scientist in Scotland, the other a Nigerian nurse in tech – they are from vastly different backgrounds, but share more in common than meets the eye, and have already begun to shape an inclusive future for researchers from all walks of life.

Through lived experiences, they explored the real-world barriers they faced – from underrepresentation and visa limitations to the invisible weight of imposter syndrome — and the communities and infrastructures that helped them keep going: OLS, the Carpentries, and the SSI.

They spoke of using their platforms to build better pathways into research and research software engineering, especially for those who never imagined they belonged in these spaces, and how institutions, allies, and community members play an active role in creating more equitable, mentally healthy spaces — and why your involvement matters.

Title: From Isolated to Continuous Automated Sign Language Recognition

Abstract: Sign languages are full-fledged visual natural languages combining manual and non-manual features. As the name suggests, Automated Sign Language Understanding (ASLU) aims to automate tasks involving sign language. A primary obstacle to ASLU is the creation of appropriate datasets. Indeed, most datasets focus on materials gathered from TV broadcasts covering limited topics, which fail to accurately reflect sign language in the wild. Moreover, annotating such datasets is a prohibitively costly process. With the end goal of Sign Language Translation (written/spoken language to sign language) in mind, ASLU research has transitioned from Isolated to Continuous Sign Language Recognition. However, sign language intricacies have made this transition non-trivial.

Title: Enhancing Deep Learning Approaches for the Automated Monitoring of Dense Seabird Colonies

Abstract: Cliff-nesting birds serve as valuable indicators of marine ecosystem health, yet dense populations and remote habitats present significant challenges for automated monitoring. With current state-of-the-art object detectors often failing under the conditions of extreme crowding and occlusion, this project aims to develop and refine deep learning techniques that enable the fine-grained, automated analysis of seabird colonies. Current work explores semi-supervised learning strategies that leverage domain-shifted knowledge to reduce the need for exhaustive annotation across complex image datasets. These methods not only reduce the laborious process of manual annotation but also demonstrate promising improvements in performance across the long-tailed species distribution. While ongoing efforts are directed at further optimising these models, future work will leverage additional spatial information with the aim of supporting richer insights into behavioural dynamics within these populations.

SACHI Seminar – Prof Sampsa Hyysalo: Design Participation | Fri 23 May, 15:00–16:00, JCB 1.33A

We are excited to invite you to a special SACHI seminar this week with Prof Sampsa Hyysalo, who will be visiting us from Aalto University in Finland. This is a great opportunity to hear from one of the leading voices in participatory design and user innovation.

📅 Friday 23rd May | 🕛 15:00 – 16:00 PM | 📍 JCB, Room 1.33A

Title:

Design Participation: Changing Roles of Users in Innovation and Research

Abstract:

In this talk, Sampsa will introduce ideas from his forthcoming book Design Participation (September 2025, cover attached), which presents doable and demonstrated ways by which design can become a major contributor to social and environmental change. This entails a shift from seeking to define solutions to opening spaces in which others—activists, entrepreneurs, civil servants, neighbourhood communities, politicians (and so on) —can effectively elaborate on and find (re)solutions to the matters they are facing. He will reflect on over two decades of research, offering insights into how participatory methods can help tackle complex social and environmental challenges. The talk will draw from work in health tech, energy transition, and civic design.

This session should be particularly relevant to colleagues working in Human-Computer Interaction, Science and Technology Studies, systems design, and research that intersects with communities, policy, and practice.
