Association for Computing Machinery's Special Interest Group on Computer Human Interaction (or ACM SIGCHI) is an international society for professionals, academics and students who are interested in human-technology and human-computer interaction.
Through over 20 sponsored and over 40 in-cooperation conferences, publications, web sites, and other services they provide several forums for discussion.
SIGCHI also offers workshops and outreach, and promotes informal access to a wide range of individuals and organizations involved in HCI.
ACM SIGCHI facilitates an environment where its members can invent and develop novel technologies and tools, explore how technology impacts people’s lives, inform public policy, and design new interaction techniques and interfaces.
Overall, the mission of ACM SIGCHI is to support the professional growth of its members who are interested in how people interact with technologies and how technology changes society.
