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 We seek original, unpublished papers documenting original research contributions, practice and experience, or novel applications, from all areas of spatial user interaction.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.
