We invite you to participate in the ACM Symposium on Spatial User Interaction 2016, which will be co-located with UIST 2016 in Tokyo, Japan. We seek original, unpublished papers documenting original research contributions, practice and experience, or novel applications, from all areas of spatial user interaction. User interface evaluations are strongly encouraged for every publication in this venue.

The symposium solicits full and short papers. Papers are of variable length, and paper length must be based on the weight of the contribution. Full papers (normally 8 pages, maximum 10) should describe research or design work within the scope of spatial user interaction. Short papers (up to 4 pages) should address the same topic, but may include preliminary results or conceptual ideas. Submitted papers should be anonymous for the double blind reviewing process, led by an international program committee. Submissions must not be previously published or accepted for publication elsewhere and must not be under review by any other publication venue during SUI 2016's reviewing period. All submissions should be prepared in the ACM SIG Proceedings format (http://www.acm.org/publications/article-templates/proceedings-template.html/)

Please note that an abstract submission is required in advance of the submitting the paper, in order to facilitate the assignment of reviewers. Supplementary videos are strongly encouraged, but not required. Submissions should address one or more of the following topics within spatial user interaction. Unlisted but strongly related topics are also welcome.

- Spatial interaction techniques - Spatial user interface metaphors - Spatial input devices and technology - Interaction on spatial, stereoscopic, and 3D displays - Evaluation methods for spatial user interaction - Collaborative interaction in 3D space - Design and user experience (UX) for spatial user interaction - Applications of human spatial perception to interaction - Adaptive and perceptual-inspired spatial user interaction - Applications of spatial UIs, such as games, entertainment, CAD, education. - Gesture-based spatial interaction - Tangible spatial user interaction - Multi-touch technologies for spatial user interaction - Desktop interfaces for spatial interaction - Multisensory and other novel forms of spatial user interaction

Accepted work will be archived in the ACM Digital Library, and will be provided as open-access for the first month following the symposium. Selected SUI papers will be presented in a special poster track at UIST 2016. Selected SUI demos will also be demonstrated at UIST 2016. For accepted submissions, at least one author must register for the symposium and present the work. If no author is registered by the early registration deadline, the accepted work will be withdrawn from the proceedings and digital libraries.

More information is available at sui-symposium.org.

Submissions: Papers, posters, and demos must be submitted through the online submission system (http://precisionconference.com/~sigchi)
