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) as well as smaller conferences such as Fun and Games and Gamification. CHI PLAY is sponsored by the ACM Special Interest Group for Computer-Human Interaction (SIGCHI). All accepted submissions will be distributed in the CHI PLAY Conference Proceedings available in the ACM Digital Library, where they will remain accessible to thousands of researchers and practitioners worldwide.
