Archival Papers and Notes document work that makes a lasting and significant contribution to our knowledge and understanding of human-computer interaction. The CHI 2009 Organizers have combined the review and submission processes for Papers and Notes, so they are no longer separate submission venues.
Contemporary Trends provoke, intrigue, and inspire the CHI audience. These submissions record the history of HCI practice and innovation outside of the scope of traditional archival papers.
Competitions provide students with an opportunity to work on challenging problems, to exchange ideas, and to compete for awards that provide recognition of excellence.
Other new venues that extend the boundaries of the CHI Conference are sometimes hosted by the various CHI Communities, such as the Design Community Events and Design Theatre of CHI 2008. Additional venues for CHI 2009 will be added to this call as the community chairs develop specific plans for them.
Recent CHI conferences have a short opening session each day with 30-second synopses of all Papers/Notes and Case Studies that will be presented that day. This session is known as CHI Madness. The CHI Madness Guide for next year's conference will be available here later.
