Pedestrian trajectories are used to learn about human behavior in public space and the impact of spatial features on pedestrian flows. Currently, these trajectories are collected manually, with self-tracking devices, or with video cameras. Even when trajectories are obtained using computational techniques, such as using computer vision to trace them in space, these datasets are not made available for reproducibility or comparative studies between different locations. To close this gap, this paper makes available the data of pedestrian trajectories collected in 39 European squares. Firstly, we summarize the data collection process which was based on collecting footage from publicly available webcams. Secondly, we describe the process of trajectory extraction entailing object detection, tracking, and georeferencing. Lastly, we describe the data cleaning and validation steps that lead to the final dataset. The dataset ultimately includes 348,300 pedestrian trajectories extracted from 193 hours of video footage, collected at different times of the day, during working days and weekends, and during the Spring and Summer season. ...

A social and spatial capital approach

Journal article (2026) - M. van Gils, J. Weeland, G. Slingerland, C. Wehrmann, O. Trienekens, M. J. van Dorst
This study explores how residents use and experience their living environment, focusing on the social affordances of neighbourhood places. Through narrative mapping in group sessions in a case study neighbourhood in Rotterdam, nineteen residents, including less-heard groups, mapped their living environments and reflected on their experiences. While residents primarily engage within their neighbourhood, perceptions of safety and territorial claims shape how places are used, particularly in parks and community hubs. By foregrounding lived experience, the study shows how social affordances take shape in neighbourhood places and give rise to uneven potentials for social and spatial capital formation. ...

Participatory design in sensitive contexts involves substantial invisible extra work that rarely appears in project plans or publications. At the same time, close collaboration with groups in sensitive contexts can expose researchers to significant emotional demands. While both invisible work and emotional labour have been discussed in CSCW and PD, little attention has been paid to how they intersect. In this reflection paper, we analyse four heterogeneous practice-based computing projects to examine the co-constitution of emotional labour and extra work. We thereby analyse how extra work shapes researchers’ emotional experiences and how emotional demands generate additional work. Drawing on cross-case analysis in the tradition of design case studies, we identify three recurring emotional patterns: (1) responsibility and moral obligation, (2) uncertainty, insecurity, and lack of control and (3) frustration, anger, and ethical tension. We show how these patterns are closely tied to institutional and structural conditions such as funding precarity, sustainability gaps, and organisational instability. By conceptualising emotional labour and extra work as mutually reinforcing, we contribute a more integrated understanding of participatory research practice and argue for greater visibility and recognition of researchers’ emotional work as a prerequisite for sustainable and responsible collaboration. ...

A conceptual framework to embed digital participation in planning processes for citizen empowerment

Journal article (2026) - J. E. Goncalves, G. Slingerland, S. Sarabi, G. Dane
Digital participation tools hold the promise to empower citizens and local communities to address urban development challenges. However, although many scholars have experimented with digital tools for citizen engagement, their efforts remain largely disconnected from planning practice. To address this disconnection, this paper analyses digital participation in planning from three perspectives: participatory planning, citizen engagement level, and human–computer interaction (HCI). We considered a wide range of digital participation tools, from tools designed for research projects to commercial and open-source tools. Our results show that there are two levels of “power mediation” and their “mediating actors” in digital participatory planning: (1) the digital tool and the HCI designer who creates the tool, and (2) the planning cycle and the planner who defines the participatory process. We furthermore highlight the importance of embedding participation tools in complementarity with each other to empower citizens at different levels. Taking these two insights into account, we developed an integrated framework – the EmpowerCycle – to embed digital participation tools in planning processes for citizen empowerment. The framework addresses the disconnection between digital tools and planning practice, supporting both researchers and practitioners in the design and implementation of digital participation tools in planning practice and decision-making processes. ...

Design for and with values in designing for social change (Design Ethics SIG)

Journal article (2026) - Deger Ozkaramanli, Fatima Zahra Abou Eddahab-Burke, Sine Celik, Geertje Slingerland, Michael Nagenborg, Natalia Gulbransen-Diaz, Leigh Anne Hepburn
This editorial introduces the theme track ‘Design for and with values in designing for social change’. Building on prior work that frame ethics as an invitation to care, the track focuse on values as a central construct in socially engaged design. It responds to a growing need to move beyond abstract value frameworks toward understanding how values are elicited, surfaced, negotiated, and enacted in practice. Drawing on 24 selected papers, we reveal a strongly interdisciplinary collection where participatory design emerges as a dominant method. The contributions are organized into four overlapping themes revolving around the concepts of power, methods, dignity and care. The track highlights both instrumental and critical approaches as well as top-down and bottom-up value articulations. With this, it emphasizes the importance of context, relationality, and reflexivity in socially engaged design. ...

It discusses the relevance, applications, and different methods of community engagement in the built environment. The inclusion of main take-away, recommendations for community engagement, and a range of example projects demonstrating various methods, bridge the gap from scientific knowledge to application in practice. ...
The advent of complex socio-technical systems in modern society calls for teaching value-based participatory design in engineering curricula. Yet, no scientific literature supports teachers in this effort. This paper introduces a teaching approach called “value-based participatory design of complex socio-technical systems” and reports on its implementation. It emphasizes the importance of actively involving stakeholders and tapping into their values from the very start of the design process. Following this approach, students learn to (1) design with stakeholders, (2) identify key values and conflicts to create a value-based mission statement, (3) navigate uncertainties, (4) adopt an iterative design process, and (5) recognize that only stakeholders can define what works best. Results of an academic course based on this approach confirm its value and importance for engineering curricula. ...

Place-making is a promising approach to foster strong communities in cities. While participation has always been central to urban place-making, novel approaches such as using co-design and digital technologies change how stakeholders participate in the design of place-making interventions and the potential effect of these interventions. These new approaches open up questions on how participation works in place-making and how it is facilitated to achieve the intended outcomes. Through a literature review, 23 articles were selected and analysed using qualitative analysis informed by program theory. This allows us to understand the goals and workings of participation in place-making and its influence on the place-making itself. Findings include that designers of place-making interventions often do not explicitly consider their participation goal in selecting participatory mechanisms, and that place-making efforts driven by physical space are most effective in achieving impact. ...

The role of interface design in digital engagement

"With a large part of the built environment privately owned in many European cities, citizen engagement is crucial for the success of sustainability initiatives in urban areas. The use of digital platforms and tools can support this process, given their potential to enable remote participation, reach a large number of citizens, and enhance governance transparency. However, many digital platforms for citizen engagement in sustainability action remain underutilised.

This study adopts a user-centric perspective to analyse the interface design of over ten digital platforms and identify design elements that hinder or foster engagement. Our analysis highlights four main interface issues: disconnection between scientific data and personal experience, complex navigation, information overload, and limited opportunities for action.

To overcome these limitations, we developed a set of design guidelines addressing four themes: Awareness and framing, Individual and collective action, Effective use of data, and Navigation and visuals. We implemented these guidelines in two prototypes, focusing on heat waves and biodiversity loss in urban areas. The prototypes were tested in workshop settings with positive feedback from participants, corroborating the importance of citizen-centric interface design in ensuring effective citizen engagement." ...

Co-design has been widely applied to develop interventions supporting behavior change. While numerous co-design propositions have been developed, applying these in practice often leads to difficulties and tensions. This study aims to review the co-design propositions and understand the dilemmas when applying them. A literature review was conducted, and twelve co-design propositions were identified after qualitative analysis. The study found that some co-design propositions conflict because they align with an idealistic versus a realistic perspective. By studying these conflicts indepth, seven dilemmas were identified at the intersection of realist and idealist propositions. Implications of the findings on design for behavior change were discussed, and this paper serves as a starting point to help researchers and practitioners identify, articulate, and navigate these dilemmas to achieve successful co-design outcomes. ...

The rapidly expanding rural community (often called rurban) is a new place for CSCW with unique sociogeographic characteristics that give rise to the need for adapted participatory practices. Socially Engaged Art (SEA) offers pluralistic and critical approaches to participative rurban CSCW to meet this need. This paper provides a case study of SEA-informed CSCW in an Irish rurban community. An online digital art summer school was delivered to young residents of Northrock using freely available digital collaboration and creation tools. Young people in rurban communities are navigating personal, social and political issues in a complex and evolving environment. In this summer school, SEA was applied to explore these issues through the creation and sharing of digital art on participant experiences and hopes for the future. The summer school hoped to promote critical thinking, confrontational dialogue and greater mutual understanding. We found that rapid creation and critique of a range of digital art expressions of social issues accessed nuanced and contradictory experiences, bringing them into dialogue with each other while supporting mutual understanding and new perspectives on rurban place and identity as they evolve. We propose integrating SEA into CSCW with young people in liminal and transitional communities such as the rurban to explore complex lived experiences in pursuit of more equitable futures and sustainable community expansion. We also draw attention to the usefulness of readily available digital and online tools in supporting CSCW in creative workshop situations. ...

Citizen engagement in urban planning is essential to designing urban spaces that are just and responsive to societal challenges. Consequently, local stakeholders are invited into urban co-creation processes. Digital tools are often used in this process to shape urban futures together. This paper explores what role digital technologies play in urban co-creation through five case studies from European cities that were presented at a workshop during the 11th Communities and Technologies conference. The Co-Design Framework is used to analyse the cases and understand how digital tools support collaboration on different levels throughout the design cycle. The findings help to design more effective digital tools for urban co-creation and provide an analysis methodology to compare and contrast urban co-creation practices across cases varying in scale, time, and utilised tools. ...

Fast growth of cities decreases the quality of life in these places. In response, Municipalities install policies aiming to improve local livability. While literature suggests social structures to have a defining impact on policy effectiveness, current evaluation metrics are not able to take this into account. This paper presents the Social Neighbourhood model, an agent-based model used to simulate and explore how livability changes in a neighbourhood given various social structures and policies. The model is applied to a neighbourhood in The Hague, Netherlands. The main result of the modelling experiments is that social structures have a very strong influence on whether or not a policy to improve livability is effective. Three hypotheses, concerning this relationship between social structures, livability, and policy interventions are drawn up as a starting point for future research. ...
Identifying the diverse and often competing values of citizens, and resolving the consequent public value conflicts, are of significant importance for inclusive and integrated urban development. Scholars have highlighted that relational, value-laden urban space gives rise to many diverse conflicts that vary both spatially and temporally. Although notions of public value conflicts have been conceived in theory, there are few empirical studies that identify such values and their conflicts in urban space. Building on public value theory and using a case-study mixed-methods approach, this paper proposes a new approach to empirically investigate public value conflicts in urban space. Using unstructured participatory data of 4528 citizen contributions from a Public Participation Geographic Information Systems in Hamburg, Germany, natural language processing and spatial clustering techniques are used to identify areas of potential value conflicts. Four expert interviews assess and interpret these quantitative findings. By integrating quantitative assessments with the qualitative findings of the interviews, we identify 19 general public values and nine archetypical conflicts. On the basis of these results, this paper proposes a new conceptual model of ‘Public Value Spheres’ that extends the understanding of public value conflicts and helps to further account for the value-laden nature of urban space. ...

Recent interest in biodiversity to combat climate crises led governments to use data platforms and sensing tools to monitor, conserve and increase city biodiversity. Given that most of these tools are designed for expert users and most city space is privately owned, there is a growing need for urban living labs (ULLs) approaches that combine community co-design with HCI for biodiversity. This paper develops and explores the BULL (Biodiversity Urban Living Lab) approach, building on the existing City Commons HCI framework, using research-through-design and action research methods. A BULL approach should not only engage citizens but also lead to opportunities for individual and collective action towards biodiversity as perceived common. Next to this, ecological and technological entities as non-human actors need to be involved in community-based co-creation in BULLs. The BULL approach provides a process and specific tools for multi-stakeholder groups, including more-than-human ones, to experiment with opportunities for more biodiversity in a local community, resulting in individual and collective action. ...
