The ACM Symposium on Spatial User Interaction (SUI) 2015 is the third international symposium focused on the user interface challenges that appear when users interact in the space where the flat, two-dimensional, digital world meets the volumetric, physical, three-dimensional (3D) space we live in. This considers both spatial input and 3D output, with an emphasis on the issues around interaction between humans and systems.

Due to the advances in 3D technologies, spatial interaction is now more relevant than ever. Powerful graphics engines and high-resolution screens are now ubiquitous in everyday devices, such as tablets and mobile phones. Moreover, new forms of input, such as multi-touch, finger and body tracking technologies are now easily available. In this environment, spatial UIs are transitioning out of the research community and game industry. More and more commercial 3D systems with spatial interaction capabilities exist, many priced at the consumer level. Until now, the challenges, limitations, and advantages of using this third dimension for human-computer interfaces have not been well understood. These questions will only become more relevant as the associated technologies continue to cross the barrier towards wide adoption.

The goal of the symposium is to provide an intensive exchange between industrial and academic researchers working in the area of spatial user interaction and to foster discussions among participants. ACM's Special Interest Groups on Graphics and Computer-Human Interaction (SIGGRAPH and SIGCHI) co-sponsor the event. The two-day symposium will be held in 2015 in conjunction with ACM SIGGRAPH 2015, and will take place prior to the conference.

We invite you to participate in the ACM Symposium on SUI 2015. We seek original, unpublished papers documenting original research contributions, practice and experience, or novel applications, from all areas of spatial user interaction.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 2015's reviewing period. All submissions should be prepared in the ACM SIG Proceedings format:

www.acm.org/publications/article-templates/proceedings-template.html

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

For accepted papers and posters, at least one author must register for the conference 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.

Papers must be submitted through the online submission system: precisionconference.com/~sigchi
