UIST (ACM Symposium on User Interface Software and Technology) 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 & web user interfaces, tangible & ubiquitous computing, virtual & augmented reality, multimedia, new input & output devices, and CSCW. The intimate size, single track, and comfortable surroundings make this symposium an ideal opportunity to exchange research results and implementation experiences.

Accepted papers will be published in the UIST 2011 Conference Proceedings and the UIST 2011 Video Proceedings, and will be included in the ACM Digital Library. The primary author of each accepted paper will receive an Author Kit with detailed instructions on how to submit a final, publication-ready version of the paper. Accepted demos and posters will be made available to the conference attendees digitally.

We recommend that prospective authors consult the UIST 2011 Author's Guide. This document contains information on the reviewing process and a description of what constitutes an excellent UIST contribution, including the page format for all submissions.

We only accept electronic submissions. To submit, see the UIST Electronic Submission site (http://www.precisionconference.com/~sigchi).

Videos accompanying submissions should be submitted through the UIST Electronic Submission Site. Although papers must stand on their own, submitted videos will be sent to reviewers as supporting material. We refer authors preparing a video for UIST to the Video Guide. Please do not be intimidated by the guide. Videos are viewed only as supporting material, and authors of accepted papers will have the opportunity to prepare a more polished final video presentation for inclusion in the DVD proceedings and as supplemental material in the ACM Digital Library.

When submitting your video for review, please encode your video in a format that works across as many platforms as possible without the installation of additional codecs (i.e., it is best if your video will play on vanilla versions of Windows Media Player and/or Quicktime player). Please note that the total aggregate size for a submission cannot exceed 50 MBytes (including all documents and additional material).
