SIGDOC is the Association for Computing Machinery's Special Interest Group (SIG) on the Design of Communication (DOC). Until 2003, SIGDOC focused on documentation for hardware and software. With the shift in focus from documentation to the "design of communication," SIGDOC better positioned itself to emphasize the potentials, the practices, and the problems of multiple kinds of communication technologies, such as web applications, user interfaces, and on-line and print documentation.
SIGDOC focuses on the design of communication as it is taught, practiced, researched, and theorized in various fields, including technical communication, software engineering, information architecture, and usability, etc.
The traditional SIGDOC member was likely to be teacher, researcher, and/or practitioner of computer documentation. Today, a member of SIGDOC is likely to be a teacher, student, researcher, or practitioner of technical communication, computer science, user interface/interaction design, or a related field.
