PhillyCHI is the Philadelphia region’s chapter of the Association for Computing Machinery's special interest group on computer-human interaction (SIGCHI). We're an interdisciplinary academic and professional group interested in human-computer interaction, user experience, usability, and other related disciplines. We are professionals, academicians, and students who are passionate about understanding the design, development, and use of computer-based systems. We come from various backgrounds and work in fields ranging from interface design, to programming, copywriting and user research. We hold monthly meetings to discuss current topics in HCI. We also host monthly social events to allow folks an opportunity to network and socialize. All PhillyCHI meetings and events are free and open to the public.
