[Quick Link: http://www.acm.org/uist] We are happy to announce that UIST 2003, the Sixteenth Annual ACM Symposium on User Interface Software and Technology, will be held in Vancouver, British Columbia, Canada on November 2-5, 2003. UIST is the premier forum for innovations in the software and technology of human-computer interfaces. Sponsored by ACM's special interest groups on computer-human interaction (SIGCHI) and computer graphics (SIGGRAPH), UIST brings together researchers and practitioners from diverse areas that include traditional graphical user interfaces, virtual and augmented reality, multimedia, new input and output devices, and CSCW. The intimate size, the single track, and comfortable surroundings make this symposium an ideal opportunity to exchange research results and implementation experiences. UIST 2003 is soliciting full-length research papers, shorter TechNotes, posters, and demos. In addition, UIST will hold its first Doctoral Symposium and its third interaction design contest. Key dates: Papers and Technotes due: March 31, 2003 Demos and Posters due: June 20, 2003 New this year -- UIST is being held overlapping with ICMI-PUI 2003, the International Conference on Multimodal Interfaces. Attendees will have the opportunity to register for both conferences at a substantial discount. For more information, please visit the UIST 2003 web site at http://www.acm.org/uist.
