Proceedings of the 33rd Annual ACM Conference on Human Factors in Computing Systems

Welcome to CHI 2015, the premier international forum for human-computer interaction (HCI). In its early days, HCI focused on optimizing interactions between a user and a computer. Today, computers pervade our world, impacting our lives in varied and subtle ways. By never focusing solely on technology itself but always on innovations and their effects throughout human lives, HCI has increasingly come to mean human-centered innovation.
