The ACM Special Interest Group on Computer-Human Interaction (SIGCHI) is the world’s largest association of professionals who work in the research and practice of human-computer interaction (HCI). We are an interdisciplinary group of computer scientists, software engineers, psychologists, interaction designers, graphic designers, sociologists, multi-media designers, information scientists, and anthropologists, just to name some of the domains whose special expertise come to bear in this area. What brings us together is a shared understanding that designing useful and usable technology is an interdisciplinary process, and when done properly it has the power to transform lives. SIGCHI has almost 70 active chapters across 6 continents, which aim to promote local support networks for HCI professionals.

You can sign up for SIGCHI membership on the ACM website. If you are a member currently, you can check your membership status and expiration date by logging in to MyACM and navigating to the ‘My Services’ section. Note that SIGCHI membership is different from ACM membership; one does not grant you the other. SIGCHI membership is relatively inexpensive in comparison to ACM membership and grants a different set of benefits. These are listed below, and the list is growing.
