Gomez Ortega, A. (author), Bourgeois, Jacky (author), Kortuem, G.W. (author)Most people interact with digital technologies that collect personal data about their behavior and experiences, leaving behind a data trail. The data within this trail is abstract and difficult to interpret; still, people often need to decide about its collection and distribution. Hence, it is paramount to support personal data literacy, for...conference paper 2024

Gomez Ortega, A. (author), Noortman, Renee (author), Bourgeois, Jacky (author), Kortuem, G.W. (author)Most people are entangled with an ever-growing trail of data that results from their daily interactions with products and services. Yet, they are hardly aware of the nature and characteristics of the data within this trail. We design dataslip, a provocative artifact that materializes the personal data trail into a receipt and aims to elicit...conference paper 2024

Bourgeois, Y. (author), Giordano, Fabrizio (author), Cazaux, S.M. (author), Schrijer, F.F.J. (author)The discovery of vast subsurface oceans hidden under kilometers of ices on icy moons in our Solar System has sparked worldwide interests in ascertaining their potential habitability. In the case of Saturn’s moon Enceladus, supersonic plumes of water vapour and icy grains have been observed by the Cassini mission spewing from the surface, giving...abstract 2024

(author)Behavioral data is ubiquitous in products, services, and systems that people interact with. It is increasingly used by design and HCI researchers and practitioners throughout their human-centered and participatory design processes. The highly dynamic nature of behavioral data makes it deeply intertwined with people, their behavior, and their...conference paper 2023

Gomez Ortega, A. (author), Milias, V. (author), Broadhead, J.S. (author), van der Valk, C.P. (author), Bourgeois, Jacky (author)As we navigate the physical and digital world, we unknowingly leave behind an immense trail of data. We are informed about this via lengthy documents (e.g., privacy policies) or short statements (e.g., cookie popups). However, even when we know that data is collected, we remain largely unaware of its nature; what information it contains and how...conference paper 2023

Meijer, Wo (author), Verhoeff, Bent (author), Verma, H. (author), Bourgeois, Jacky (author)The digitization of services and global lock-downs have led an explosion of delivery services, which use gig-workers as delivery personnel. They can face apathy from both their employers and users of the service. Previous studies focused on mediating interactions between workers or workers and tasks. However, delivery presents the opportunity...conference paper 2023

Gomez Ortega, A. (author), Bourgeois, Jacky (author), Hutiri, Wiebke (author), Kortuem, G.W. (author)As we navigate physical (e.g., supermarket) and digital (e.g., social media) systems, we generate personal data about our behavior. Researchers and designers increasingly rely on this data and appeal to several approaches to collect it. One of these is data donation, which encourages people to voluntarily transfer their (personal) data...journal article 2023

Gomez Ortega, A. (author), Bourgeois, Jacky (author), Kortuem, G.W. (author)Digital technologies have increasingly integrated into people's lives, continuously capturing their behavior through potentially sensitive data. In the context of voice assistants, there is a misalignment between experts, regulators, and users on whether and what data is 'sensitive', partly due to how data is presented to users; as single...conference paper 2023

Gomez Ortega, A. (author), Bourgeois, Jacky (author), Kortuem, G.W. (author)Recently, methods and approaches such as Participatory Data Analysis, Data-Enabled Design, and Contextual Inquiry have highlighted how design activities can benefit from behavioral data. This data offers new ways to learn from what people do and how they do it, across time and space. However, behavioral data introduces changes and frictions to...book chapter 2023

Gomez Ortega, A. (author), Bourgeois, Jacky (author), Kortuem, G.W. (author)Ubiquitous wearable and mobile technologies generate vast amounts of data from sensors and self-logging applications. This data creates opportunities to better understand people’s behavior and inform research on intimate topics such as menstruation. However, in design and HCI research, reconstructing the context in which data was collected and...conference paper 2022

(author), Nedić, Dajana (author), Jimenez Garcia, Juan (author), Meijer, Wo (author), Kumar Chaudhary, Pranshu (author), Bourgeois, Jacky (author)Designers and HCI researchers from industry and academia have been exploring the opportunities that emerge from incorporating behavioral data into the design process. For this, designers employ and combine data from multiple sources, multiple scales, and types to obtain valuable insights that inform and support design decisions. This combination...conference paper 2022

Lu, Jiahao (author), Gomez Ortega, A. (author), Gonçalves, M. (author), Bourgeois, J. (author)With the advance of the Internet and the Internet of Things, an abundance of 'big' data becomes available. Data science can be incorporated in design, which brings forward various opportunities for designers to benefit from this new material. However, the designer's perspective and their role remains unclear. How do they think about and...journal article 2021

Liu, J. (author), Draganov, D.S. (author), Ghose, R. (author), Bourgeois, Q. (author)Detecting small-size objects is a primary challenge at archaeological sites due to the high degree of heterogeneity present in the near surface. Although high-resolution reflection seismic imaging often delivers the target resolution of the subsurface in different near-surface settings, the standard processing for obtaining an image of the...journal article 2021

Jahangir, S. (author), Ghahramani, Ebrahim (author), Neuhauser, Magdalena (author), Bourgeois, Sébastien (author), Bensow, Rickard E. (author), Poelma, C. (author)The objective of this study is to investigate the collapsing behavior of cavitation, which leads to the erosion of material. An experimental examination was conducted in a channel with a semi-circular cylinder obstacle, which serves as a “vortex cavity” generator. Cavitation was achieved by employing a range of pressure differences over the...journal article 2021

Gomez Ortega, A. (author), Bourgeois, Jacky (author), Kortuem, G.W. (author)In-The-wild research allows the HCI community to gain insights into personal behaviour and characteristics. For designers and researchers, this means having access to rich spatiotemporal insights reflecting user's characteristics, behaviours, and needs. However, designerly contexts require contextualized and meaningful data, and collecting it...conference paper 2021

Ghahramani, Ebrahim (author), Jahangir, S. (author), Neuhauser, Magdalena (author), Bourgeois, Sébastien (author), Poelma, C. (author), Bensow, Rickard E. (author)In this paper, the cavitating flow around a bluff body is studied both experimentally and numerically. The bluff body has a finite length with semi-circular cross section and is mounted on a surface in the throat of a converging-diverging channel. This set-up creates various 3D flow structures around the body, from cavitation inception to...journal article 2020

Nanbakhsh, K. (author), Kluba, M.M. (author), Pahl, Barbara (author), Bourgeois, Florian (author), Dekker, R. (author), Serdijn, W.A. (author), Giagka, Vasiliki (author)Platinum is widely used as the electrode material for implantable devices. Owing to its high biostability and corrosion resistivity, platinum could also be used as the main metallization for tracks in active implants. Towards this goal, in this work we investigate the stability of parylene-coated Pt tracks using passive and active tests. The...conference paper 2019

Kroon, E.J. (author), Huisman, D.J. (author), Bourgeois, Q. P.J. (author), Braekmans, D. (author), Fokkens, H. (author)The introduction of the Corded Ware Culture (3000–2500 BCE) is considered a formative event in Europe's past. Ancient DNA analyses demonstrate that migrations played a crucial role in this event. However, these analyses approach the issue at a supra-regional scale, leaving questions about the regional and local impact of this event unresolved...journal article 2019

(author), Bourgeois, Jacky (author), Danford, Gerard (author)One promising way to cope with changing requirements from the labor market in the domain of Science, Technology, Engineering and Mathematics (STEM), but also to keep the field up to date, to start innovations and to advance the STEM domain as such is the use of student labs. In these labs, students work together in small groups imitating...journal article 2019
