The Association for Computing Machinery (or ACM) hosts an annual Conference on Human Factors in Computing Systems (frequently refered to as CHI). This series of academic conferences is generally considered one of the most prestigious in the field of human-computer interaction. It is hosted by ACM SIGCHI, the Special Interest Group on Computer-Human Interaction and is a place where researchers and practitioners gather from across the world to discuss the latest in interactive technology. CHI attracts thousands of international attendees and has been held annually since 1982. For more information on CHI, http://sigchi.org/ (visit )http://sigchi.org/ (SIGC)HI.org
