CHI NL Community Event 2024 | April 12 | Utrecht

The CHI NL Community Event 2024 will take place at Utrecht University on Friday April 12 2024.


CHI NL will bring together the local HCI community again in 2024. This year, we gather at Utrecht University, where we will host keynotes and paper presentations and provide the possibility to gather feedback on work that did not make the cut. Of course, there will also be room for networking and social activities on a smaller and cosier scale than at the CHI conference. We are still working on finalising the program – an update on this will follow shortly. We hope to see all our fellow HCI researchers from around the Netherlands for this nice gathering. This event is supported by ACM SIGCHI.

Call for submissions

Many researchers will have submitted papers to the ACM CHI Conference on Human Factors in Computing Systems or other SIGCHI conferences. We call for both accepted and rejected submissions for CHI and other SIGCHI conferences. We will host sessions where authors can practice their presentation or get feedback on their work for a resubmission. Further, we invite HCI research groups to submit a poster introducing their group and their activities to the CHI NL community day. These posters allow the participants of the event to find colleagues with similar research interests as themselves, even if they cannot attend. The deadline for submitting your work is the 29th of March.

Keynote speakers

Prof. Dr. Vanessa Evers (University of Twente)

Title: Designing socially intelligent technology

Abstract: In futurist research, we envision new robotic possibilities and think through the consequences of these (im)possible innovations for people and their impact on society. In imagining this future and developing Social AI and Social robotics solutions, we have been imagining what future robotic services may look like, and study the social and societal consequences. In this presentation I will discuss projects in which we created social robot technology; explain how we went about designing integrated AI driven robots that were envisioned to operate in everyday environments and how we studied the impact of these controversial technologies on people’s lives. Also, there will be a lot of interesting videos to watch as we learned to make robots for people through trial and error.

She has presented her work internationally at high profile events such as the World Economic Forum in Davos (2016), the European Heads of State Digital Summit in Tallinn (2017) and the ASEAN leadership conference. 

Dr. Martijn Willemsen (Eindhoven University of Technology)

Title: Better understand why your recommender system/AI works or not: the benefits of quantitative user-centric evaluation.

Bio: Martijn Willemsen ( is an Associate Professor on human decision making in interactive systems in the Human-Technology Interaction group at Eindhoven University of Technology (TU/e) and at the Jheronimus Academy of Data Science in Den Bosch (JADS), in The Netherlands. He researches the cognitive aspects of Human-Technology Interaction, with a strong focus on judgment and decision making in online environments. His research focuses on how (online) decisions can be supported by recommender systems, and includes domains such as movies, music, health-related decisions (food, lifestyle, exercise) and energy-saving measures. Together with Bart Knijnenburg, he developed a user-centric evaluation framework for recommender systems. His recent focus is on interactive recommender systems that help users to move forward, developing new preferences and/or healthier behavior, rather than reinforcing their current behaviors. Such systems can provide personalized behavioral change. Martijn also focusses on interactive and explainable AI, with recent work evaluating XAI tools and how sport coaches interacting with prediction models.
