Late-breaking is a type of news report that covers urgent news events. These include severe weather or terrorist attacks, and are usually covered by breaking news tickers that interrupt regular programming. These tickers can be augmented with lower thirds and other graphics to convey the urgency of the story. Until 24-hour news networks existed, such interruptions were typically reserved for the most critical, high-profile breaking news stories (e.g., the assassination of President Kennedy).
Submissions for LBWs are not limited in length but should be clearly written and well illustrated, with clear illustrations of key aspects of the research and compelling visual design. Presenting authors are expected to provide a poster version of their LBW at the conference, as well as a link to an online version for virtual presentation to CHI 2025 attendees.
Accepted LBWs will be published as CHI Extended Abstracts and appear in the ACM Digital Library. They will be accompanied by an optional appendix, which should only contain information not available within the main submission. The selection criteria for LBWs are strict. The work submitted must be of critical importance to the scientific community and should not be a mere extension of previously published or presented work.
