The SIGCHI 2026 conference brought together more than 5,200 researchers in Human-Computer Interaction in Barcelona. The SICAL team was presenting two articles and a poster, while the Database team co-organized two workshops.

The article "How Interface Design Choices Lead to Indirect Environmental Impacts Through Use Intensification, An empirical evaluation of Messaging Apps" written as part of a joint PhD with the University of Strasbourg, received a best paper honourable mention award. This article studies how the design of user interfaces can lead to environmental harms. The article proposes a analysis method structured around feature analysis and interviews. The article contributes design heuristics and develops theoretical contributions, proposing four categories of indirect effects, leading to the expansion of digital infrastructures.

The two workshops of the Database team are : 

• (Re-)Thinking Empathy’s Materiality in HCI
•  Co-Data: Cultivating Effective Human–LLM Collaboration for Collaborative Data Processing
