SIGCHI

SIGCHI, the Special Interest Group on Computer-Human Interaction, is a unit of the Association for Computing Machinery (ACM) devoted to human–computer interaction. It was established within ACM in 1982 to advance research, education, and professional practice in HCI and to support a global community of researchers and practitioners.

The group's flagship activity is the annual CHI Conference on Human Factors in Computing Systems, commonly known as CHI, which is widely regarded as the premier international conference in HCI. SIGCHI also supports a range of related conferences and venues, including UIST (User Interface Software and Technology), CSCW (Computer-Supported Cooperative Work), and DIS (Designing Interactive Systems), as well as regional, student, and special-interest events.

Publications associated with SIGCHI include the ACM Transactions on Computer-Human Interaction (TOCHI) and the Interactions magazine, both of which disseminate research, practice, and design guidance. The group curates awards, grants, and fellowships to recognize contributions to the field, and maintains an active online presence through the ACM Digital Library and SIGCHI websites.

SIGCHI operates through elected officers and a governance structure that includes chapters and regional affiliates worldwide. It supports professional development, education, and outreach, and serves as a focal point for researchers, designers, and educators in HCI.
