Abstract:

This thesis investigates the promotion of social well-being in cities through the concept of urban-digital hybridity, which considers social and spatial interactions—whether physical and/or digital—as inseparable in the urban context. Based on an integrative literature review, a set of indicators was identified and categorised to more comprehensively assess the effectiveness of public policies aimed at improving quality of life in technology-mediated urban environments.
The review of indicators combined traditional methodologies—such as those used in the World Happiness Report, published by the United Nations—with metrics related to physical and mental health, community participation, perception of safety, and cultural vitality, while also incorporating emerging variables derived from the use of digital media. The research methodology adapted the mapping and critical analysis of these indicators to Marichela Sepe’s Cartography of Happiness, applying it to contexts of urban-digital hybridity and combining it with empirical digital placemaking experiments.
Case studies and digital placemaking experiences were conducted in the cities of Porto and Póvoa de Varzim, involving local communities, religious institutions, and schools, exploring technological mediation as a catalyst for social bonds and the activation of public spaces. Heatmaps of interactions, together with qualitative field data, allowed the identification of correlations between patterns of urban activation, city morphology, and landscape.
As its main outcome, the research proposes three core metrics for assessing social well-being in hybrid cities: Sense of Belonging, Sense of Place, and Sense of Community, analysed in their urban, digital, and hybrid dimensions.
The thesis’ main contribution is an integrated model for assessing urban social well-being, combining physical and digital metrics to provide an operational framework for urban planning and public policy design, aiming to foster more inclusive, participatory, and well-being-oriented cities.

Inspiring the motivation to learn: Rui Rodrigues honoured with the Teaching Excellence Award on FEUP’s Day 2026

Posted on

We live in times when the motivation to discover and create seems to be threatened by the ease with which machines offer us information, already organised and interpreted. If machines seem to know everything for us, a central question arises for current teaching: why learn?

It is in this context that the role of the teacher is increasingly being put to the test. And it is precisely to this question that Rui Rodrigues, lecturer in the Department of Informatics Engineering (DEI), affirms that “the intrinsic satisfaction of discovering things, of creating things, of making things happen, of understanding what makes them work, and of sharing this with your fellow human beings” is the most obvious answer.

This educational vision resulted in Rui Rodrigues being distinguished with the Teaching Excellence Award, presented on FEUP’s Day, celebrated on January 13th. For the second consecutive year, a DEI lecturer has been honoured with this recognition, underscoring the sustained quality of the department’s pedagogical practices.

In a context where those who want to learn can often do so independently, Rui Rodrigues argues that the real challenge of teaching is: teaching people to enjoy learning.
“Indifference is all too common among students today, so I interpret this award more as recognition of the various efforts to combat this indifference than as a success in this challenge, which is never won. In this sense, it is an award that is certainly due to many of us (some even more deserving), who continually strive to find new ways to not only get the message across to the recipient, but to have it internalised.”

This approach has had a decisive impact on the careers of many students. Teresa Matos, a PhD student and colleague, recalls that it was in the practical classes in Computer Graphics that she found her area of interest: “It was in Rui’s practical classes in Computer Graphics that I found my area of interest, and it was later in the Student Computer Graphics Centre, with his constant support, that I found my way at FEUP.” She also highlights the professor’s tireless dedication to both students and colleagues, as well as his constant search for pedagogical innovation. “Seeing his tireless dedication day after day encourages me to strive to be a better educator and researcher. I consider him a true example of how to be an excellent professor.”

Pedro Silva, a former student and master’s student, also emphasises not only the professor’s scientific rigour, but also his human dimension. Throughout his academic career, he found in Rui Rodrigues a professor who was always available to answer questions and share knowledge, but it was during his dissertation that he recognised a particularly remarkable level of support. “He was a tremendous help during the writing of the document, both for his accurate suggestions regarding its structure and content, as well as for the advice he emphasised throughout the process.” Calmness, humour and empathy are traits that Pedro highlights as fundamental to overcoming the most demanding moments of the academic journey. “There are not many teachers, researchers and human beings like Professor Rui, and I hope he will continue at FEUP for many years to come.”

For Rui Rodrigues, teaching remains, above all, a deeply human exercise. In an increasingly automated world, the role of the teacher is to show that learning is not just about accumulating answers, but about developing curiosity, critical thinking and a desire to create — so that students are not only connected to the machine, but also to each other.

This award, granted ex aequo to Prof. Beatriz Oliveira, from the Department of Industrial Engineering and Management (DEGI), recognises not only the individual career of the teacher, but also a way of teaching that values pedagogy as a space for discovery, relationship and construction of meaning.

A. Augusto de Sousa honoured by GPCG – Portuguese Computer Graphics Group

Posted on

The Portuguese Computer Graphics Group (GPCG), the Portuguese chapter of Eurographics, honoured Professor António Augusto de Sousa, recently retired DEI lecturer, at the International Conference on Graphics and Interaction (ICGI’25), which took place on 13 and 14 November at the Olga Cadaval Cultural Centre in Sintra.

The session was attended by colleagues and former students who wanted to recognise the Professor’s career and exceptional contribution in the areas of Computer Graphics and Human-Computer Interaction, with special emphasis on his involvement as a founding member of the GPCG.

Recognised for his strong commitment to teaching, as well as for his constant support and enthusiasm for multiple academic and student initiatives, Professor António Augusto de Sousa leaves behind a remarkable legacy. This tribute highlighted his role as a reference and the high prestige he continues to enjoy among the Portuguese Computer Graphics and Interaction community.
In the context of this tribute, a brief historical review was requested in which the Professor revisits the founding moment of the GPCG and reflects on the journey and work developed over its 36 years of existence:

“The GPCG – Portuguese Computer Graphics Group was formally registered in 1990, having been established as a National Chapter of the international association EUROGRAPHICS.
In 1998, I was elected to the board of the GPCG, taking on the role of its second president. During this period, I initiated a series of scientific events that are still held annually today, and I promoted, on behalf of the group, the organisation of the EUROGRAPHICS 1998 conference, held in Lisbon.
I sought to create the necessary conditions for the affirmation and dissemination of the GPCG, while also encouraging collaboration with other similar groups, particularly in Spain. This cooperation was the embryo for the later creation of the SIACG conference series – Ibero-American Symposium on Computer Graphics.
Over the years, I have also held various positions in the GPCG’s management bodies, namely Vice-President (2000–2002 and 2013–2014), Treasurer (2014–2016) and Secretary of the General Assembly (2002–2008). In 2015, I led the process of digitising the minutes of all the meetings organised by the group, which were later indexed in the EUROGRAPHICS association’s digital library. More recently, I gathered and organised various historical documents, particularly those relating to the formation of the GPCG, and prepared a summary of the group’s history, which I presented at the EPCGI 2024 conference in Vila Real.

The thesis was co-supervised by Pedro Miguel do Vale Moreira (PhD), Full Professor at the Instituto Politécnico de Viana do Castelo.

Abstract:

Human gait analysis provides critical information on biomechanical function, clinical assessment, and biometric recognition, but achieving accurate and reproducible motion understanding under real-world variability remains a major challenge. Traditional motion capture techniques are dependent on expensive infrastructure and controlled environments, which limit scalability and realworld validity. This thesis addresses these limitations by developing computational methodologies that exploit both RGB and depth information to enable robust, efficient, and fully automatic gait analysis using consumer-grade sensors. The research followed a structured trajectory that encompasses dataset creation, representation design, and methodological innovation. First, an extensive review and comparative analysis of existing vision- and depth-based gait datasets identified gaps in modality diversity, annotation quality, and accessibility. To address these issues, the Gait Recognition Image and Depth Dataset (GRIDDS) was designed, acquired, and publicly released. GRIDDS provides synchronized RGB, depth, silhouette, and 3D skeletal data from 35 participants recorded under controlled conditions, establishing one of the first standardized multi-modal benchmarks for gait analysis and recognition. Building on this foundation, two novel computational gait representations were introduced that fuse two-dimensional appearance cues with three-dimensional skeletal structure to increase robustness to viewpoint, clothing, and carried-object variations. These Gait Skeleton Image (GSI) variants (joint-based and line-based) were integrated within deep learning frameworks and evaluated through extensive experiments, demonstrating competitive and, under certain circumstances, superior performance compared with established appearance-based methods across multiple datasets and covariate conditions. Finally, new methods for gait silhouette interpolation were introduced, combining deterministic geometric reasoning (BRIEF) and bidirectional deep learning (BiSINet) to reconstruct missing frames and enhance temporal coherence. The proposed interpolation techniques significantly improved downstream recognition accuracy and demonstrated strong generalization across datasets and frame-rate conditions. Collectively, the contributions of this work, which span multi-modal data acquisition, robust gait representation learning, and temporal reconstruction, advance the scientific and technological frontiers of human gait analysis, promoting reproducibility, accessibility, and applicability in both clinical and computer vision domains.

Creativity Talks | “Neurorobotics: Connecting the Brain, Body, and Environment” by Jeffrey L. Krichmar

Posted on

The seventeenth session of Creativity Talks will feature Professor Jeffrey L. Krichmar, an expert in neurorobotics and computational neuroscience at the University of California, Irvine, as the keynote speaker, presenting “Neurorobotics: Connecting the Brain, Body, and Environment.”
The talk will take place on December the 4th 2025, at 17:30, and will be moderated by Armando Sousa (DEEC).

Abstract:

Neurorobots are robots whose control systems follow structural and dynamical aspects of the nervous system. Their artificial brains can be thoroughly probed and recorded as the robot interacts with the world. Neurorobotic design principles fall into three categories that follow natural organisms: First, they must react decisively to sensory events. Second, they must have the ability to adapt, learn and remember over their lifetime. Third, they must weigh the different and sometimes conflicting options that are crucial for completing tasks. Following these principles can not only increase our understanding of how brain responses lead to flexible behavior, but they may also lead to more intelligent systems. In this talk, I will describe the field of neurorobotics and then present neurorobot interaction case studies that focus on how neuromodulation and neurohormones can influence affect, learning, and behavior.

The talk will be broadcast online:
