Abstract
CHItaly is the Biannual Conference of the Italian Special Interest Group on Computer–Human Interaction (SIGCHI) chapter. In 2021, the conference theme was "Frontiers of HCI" and the call for participation especially welcomed submissions that challenged the disciplinary boundaries of computer-mediated interactions. These CEUR workshop proceedings present the accepted research submissions to the Interactive Experiences (IEs) track, which was chaired by Maria Menendez-Blanco, Secil Ugur Yavuz, and Jennifer Liesbeth Schubert, and to the Doctoral Consortium, which was chaired by Daniela Fogli and Fabio Paternò.
