We curated a list of this year’s publications — including links to social media, lab websites, and supplemental material. We have six journal articles, 67 full papers, 30 LBWs, eleven interactivities, one alt.chi paper, one DC paper, lead three workshops and give two courses. Four papers were awarded a best paper award, and seven papers received an honourable mention.
The papers for the contributing labs were also curated in a PDF booklet by Michael Chamunorwa, and it can be downloaded here: Booklet 2023
