This meet-up will bring together members of the ACM SIGIR Information Interaction and Retrieval (CHIIR) community and the broader CHI audience to strengthen cross-community dialogue on interactive information retrieval (IIR), search interfaces, and human-centered evaluation methods. Through structured activities, networking opportunities, and collaborative brainstorming, the session aims to identify common challenges, inspire collaborations, and chart a forward-looking research agenda that connects CHI and CHIIR communities.
