Dear SIGdial members, We are pleased to announce the Call for Presentations for the workshop "SignHAI 2026," which will be held as part of HAI 2026 taking place in Osaka this November. The workshop welcomes contributions on inclusive agent design involving sign languages and other forms of communication (General Track), as well as turn-taking prediction in sign language dialogue (Challenge Track). For the Challenge Track, annotated signing-activity segments from a subset of the JSL Corpus (Japanese Sign Language Colloquial Corpus) will be released and used as evaluation data for turn-taking prediction in sign language dialogue. The deadline for presentation applications is October 14. You are required to submit only the title and abstract at the time of application; submission of a full manuscript is not required. We warmly encourage anyone interested in these topics to submit a presentation proposal. For further details, please visit the workshop website: https://sites.google.com/kyoto-u.ac.jp/signhai2026/ We look forward to your participations. SignHAI organizers. ----- Kotaro FUNAKOSHI Laboratory for Future Interdisciplinary Research of Science and Technology (FIRST), Institute of Integrated Research (IIR), Institute of Science Tokyo
