The ACM SIGCHI Annual Symposium on Computer-Human Interaction in Play (CHI PLAY) is a new international and interdisciplinary conference series (sponsored by ACM SIGCHI) for researchers and professionals across all areas of play, games and human-computer interaction (HCI), we call it: “player-computer interaction”. We invite you to come to London, England to celebrate human-computer interaction in games. CHI PLAY grew out of the increasing work around games and play emerging from the ACM annual conference on Human Factors in Computing Systems (CHI) over the last several years. The goal of the conference is to highlight and foster discussion of current high quality research in games and HCI as foundations for the future of digital play.
