Title: Digital Cultural Landscapes for Sustainable Development in Remote and Island Communities

Abstract: Heritage plays a crucial role in community identity and sustainable development, yet remote and island communities often face challenges in engaging with and protecting their landscapes. This research explores how emergent digital technologies—such as 3D modelling, VR, and AR—can enhance heritage engagement and contribute to sustainable development. Using a practice-led methodology, case studies from Scotland and Malta demonstrate how digital cultural landscapes can support climate action, institutional capacity-building, and sustainable communities. A sustainable virtual museum framework is being developed, linking heritage to real-world environmental and socio-economic challenges. This presentation highlights the findings from these case studies, and the next steps in developing an immersive digital environment for an underwater heritage site.

Title: Reimagining the Digital Gig Economy: Evaluating the economic feasibility and technological capabilities of physical cooperative gig platform

Abstract: The gig economy, fuelled by digital platforms, has transformed the labour markets around the world, offering flexibility but often at the cost of security for the worker and fair compensation. This presentation explores platform cooperatives – a democratically owned and governed alternative – as a potential solution to these challenges. I will delve into the economic feasibility and technological capabilities of physical delivery cooperatives, comparing them to traditional investor-owned platforms. By examining key performance metrics, regulatory environments, and worker empowerment, my ongoing work will assess whether platform cooperatives can achieve a comparable level of service while fostering more equitable working conditions. This presentation aims to spark discussion on the future of the gig economy and the role cooperative models can play in creating a more sustainable digital labour landscape.

Title: Engaging Culture Heritage with Authentic Characters to Support Inclusive Learning

Abstract: Digitalization opens up new opportunities for cultural heritage, and lately the exploration of virtual reality has created new forms of representation of cultural content for educational institutions, museum exhibitions, and heritage preservation organizations. High-fidelity technology allows virtual agents to simulate realistic human appearances and behaviour to interact and engage with their surroundings. This speech presents work-in-progress research regarding designing, creating and utilising authentic characters to strengthen the exhibition of cultural heritage. Through the discussion on research design and practice, this research examines the capability of characters to enrich immersion and communication with heritage. This presentation introduces the realism and authenticity of character design, clarifies the goals for digitalization for inclusive learning opportunities in SDG, and ends with future work.

Title: Behaviour Planning: A toolbox for diverse planning

Abstract:

Diverse planning approaches are utilised in real-world applications like risk management, automated streamed data analysis, and malware detection. These approaches aim to create diverse plans through a two-phase process. The first phase generates plans, while the second selects a subset of plans based on a diversity model. A diversity model is a function that quantifies the diversity of a given set of plans based on a provided distance function.

Unfortunately, existing diverse planning approaches do not account for those models when generating plans and struggle to explain why any two plans are different.

Existing diverse planning approaches do not account for those models when generating plans, hence struggle to explain why any two plans are different, and are limited to classical planning.

To address such limitations, we introduce Behaviour Planning, a novel toolbox that creates diverse plans based on customisable diversity models and can explain why two plans are different concerning such models.

Title: Leveraging Immersive Technology to Enhance Climate Communication, Education & Action

Abstract: Climate change represents one of the most pressing challenges of our time, not only in its environmental impacts, but also as a pivotal science communication problem. Despite widespread scientific consensus on the causes and mitigation strategies for climate change, public understanding remains deeply fragmented and polarized. This disconnect hinders the collective action required from individuals, organizations, and policymakers to combat global warming effectively. My research explores the potential of immersive technologies to bridge the gap between scientific knowledge and public understanding by leveraging experiential learning experiences to inspire the attitudinal and behavioural shifts necessary to address climate change.

Title: Adversarial Attack as a Defense: Preventing Unauthorized AI Generation in Computer Vision

Abstract: Adversarial attack is a technique that generate adversarial examples by adding imperceptible perturbations to clean images. These adversarial perturbations, though invisible to human eyes, can cause neural networks to produce incorrect outputs, making adversarial examples a significant security concern in deep learning. While previous research has primarily focused on designing powerful attacks to expose neural network vulnerabilities or using them as baselines for robustness evaluation, our work takes a novel perspective by leveraging adversarial examples to counter malicious uses of machine learning. In this seminar, I will present two of our recent works in this direction. First, I will introduce the Locally Adaptive Adversarial Color Attack (LAACA), which enables artists to protect their artwork from unauthorized neural style transfer by embedding imperceptible perturbations that significantly degrade the quality of style transfer results. Second, I will discuss our Posterior Collapse Attack (PCA), a grey-box attack method that disrupts unauthorized image editing based on Stable Diffusion by exploiting the common VAE structure in latent diffusion models. Our research demonstrates how adversarial examples, traditionally viewed as a security threat, can be repurposed as a proactive defense mechanism against the misuse of generative AI, contributing to the responsible development and deployment of these powerful technologies.

User-Centred Interaction Design

Students undertaking CS5042 User Centred Interaction Design were pictured prototyping their design ideas during creative thinking, and hands-on sessions earlier this month. UCID provides experience with modern design methodologies, introduces the philosophy of interaction design and involves working with actual clients.

The module delivered by Miguel Nacenta is a compulsory element for students studying on our MSc in Human Computer Interaction, a popular addition to our MSc Portfolio.

Postgraduate Dinner at Fairmont Hotel

Postgraduate student, Paul Dobra organised an end of semester celebratory dinner at the Fairmont Hotel in April. The social event marked the end of teaching and provided a chance to relax before the commencement of dissertation. Paul supplied comments and shared some photos from the occasion.

“There are rather few occasions not to be happy when you are surrounded by friends and family. Even better so when your friends are like your family, and in true computer science spirit the end of the second semester finished in a grand style: enjoying the scenic view of the North Sea from the balcony of the Fairmont Hotel and Restaurant, approximately 60 postgraduates celebrated their friendship and the successful completion of deadlines. Consisting of a lavish three-course meal and blessed with amazing weather, the event was a reminder of the true, everlasting bonds that can be forged outside university.”
