Digital Platforms for Citizen Participation

Processes for citizen participation in decision-making seek to open opportunities for people to influence agenda-setting, public budget allocation, or policy-making. In the last years, there is an increasing interest in exploring how digital platforms can support these forms of citizen participation. There are many open questions about citizen participation processes and how they become implemented digitally. What does it mean participate in decision-making processes in issues of public interest? How can digital platforms support democratic forms of participation? Who is invited to participate? In 2019, I visited the PartipaLab at the MediaLab Prado in Madrid. For six months, I collaborated with researchers, citizens, city officers on different projects about participation, technologies, and democracy. Some of the outcomes were report on the sustainability of civic technologies, and a publication on sortition as participation instrument.

Equity in Computing

Why is it important to create equal opportunities in computer science? Why do stereotypes matter? How to move from deficit approaches in diversity programmes? Research shows that there are structural and systematic issues that shape how people participate in computer science. However, these pervasive problems can not be addressed holistically, they require concrete interventions. To that purpose, in the last years, I have co-organised many activities, workshops, public events, and talks on equity in computer science. Some of the outcomes are interactive products that open opportunities for discussion and learning. All materials, instructions, and source code are available on FemTech.dk.

Political alignments in Participatory Design

How do political alignments influence how people participate in design projects? How do design affordances shape democratic participation in digital platforms? Based on the four digital democracy positions proposed by L. Dahlberg, we developed a set of cards to discuss the political alignment of participatory design projects. Unpacking how people prefer to participate in projects with a political lens is important because of their design implications. For example, participants who are aligned with deliberative forms of participation might prefer mechanisms such as consensus; while participants who are aligned with rational forms of participation might prefer decisions to be taken through voting. These cards are a design tool that has been proofed to successfully unpack important considerations in several Participatory Design projects.

Representing Matters of Concern: GRACE

GRACE is an interactive installation designed to celebrate the 70th anniversary of the “first bug ever found” by Grace M. Hooper in 1947. It is a large wooden installation built using origami, microcontrollers, sensors, and actuators with which participants can interact with their mobile phones. Conceptually, GRACE seeks to open up discussions on concerns about equity, gender, and computing. Theoretically, the design is inspired by Latour’s “object-oriented democracy”, which points to two different meanings of the word representation. On the one hand, representing is about the ways to bring legitimate people around a matter of concern (“Who is to be considered?”). The second is about presenting the different views and angles on an object of concern (“What is to be considered?”). Since 2017, more than 1000 people have interacted with the installation in Denmark, the USA, and France.

Processes in the Formation of Publics: spazioD

How can design support the formation of publics? What processes can support publics’ formation? According to J. Dewey’s, publics are groups of people that have a mutual concern and gather together to act on it. In this project the matter of concern at stake was dyslexia. Dyslexia is a condition that entails non-normative ways of processing information. Research has predominantly focused on neurological, pedagogical, or psychological aspects of dyslexia; in this project we focused on the social construction of dyslexia. Through the development of digital platforms, interactive artifacts, and public events we challenged many of the social constructions and provided opportunities for mutual learning among parents, teachers, and experts. One of the outcomes was the “Settimana Europea della Dislessia“, an annual event that has been now taking place for three years, attracting thousands of people in the region of Trentino (IT). This project was one of the case studies in my PhD thesis, where I proposed a methodology for supporting the formation of publics.

From Participatory Design to Participatory Development: SmartCampus

Smart Campus was a project aimed at creating campus services with and for students in Trentino (IT). The project followed a participatory design approach, where students were progressively involved in the design of the campus services and eventually became part of the development of technologies. During the project we engaged in user research, prototyping, and development activities. The project had a great impact on the local context and it also led to several publications in top international conferences and high-ranking journals.

Crowdsourcing for Multimedia Retrieval: CUbRIK

CUbRIK was a project that explored ways to increase precision and relevance of Artificial Intelligence algorithms. In the project, I investigated the potentials of crowdsourcing for multimedia retrieval in machine learning, with a special emphasis on task design and ethical implications. I was the leader of the work package on Human Computation, which entailed managerial and organizational responsibilities. The work in this project led to publications in top conferences and journals, such as this crowdsourced creative commons dataset and this crowdsourcing procedure for non-obvious attributes.

Multimedia Retrieval for Recommending Systems: Near2me

Near2me is a travel recommender concept that generates recommendations based on multimedia retrieval algorithms. Near2me sought to provide “authentic” recommendations by making use of users photos on Flickr. I co-led the user evaluation of the prototype as part of the Petamedia network of excellence. The design was envisioned by Luz Caballero and co-evaluated by Valentina Occhialini.

Gesture-based interaction: Behand

Behand was a novel way of interaction that allowed mobile phone users to manipulate virtual three-dimensional objects inside the phone by gesturing with their hand. Behand provided a straightforward 3D interface and extended the phone’s input and display space. It is ergonomically appropriate and technically feasible. Behand was the outcome of a design case project with Luz Cabellero and Valentina Occhialini at the Industrial Design department of the Technical University of Eindhoven. Our supervisor was Andres Lucero, who worked for Nokia at the time. Behand won the Student Design Competition at MobileHCI in 2010.

Automatic Assessment of User Experience: UX_Mate

UX_Mate (UX Motion Activation Tracking Engine), is a software tool developed for automatic assessment of UX by means of facial motion tracking. UX_Mate brings together the advantages of EMG and approaches based on video analysis since it does not require invasive devices and can be used in natural settings, including situations with critical or varying illumination conditions. Moreover, it exploits fine-grained facial motion tracking instead of relying on a fixed emotion classifier. This feature allows taking advantage of low-intensity, mixed emotions as the ones elicited in HCI. A database of annotated and synchronized videos of interactive behavior and facial expressions, and details about the evaluation are available on our research paper.
