The poster track is an excellent opportunity to present unpublished work, receive feedback, network with experts, and initiate collaborations. We invite posters describing work in progress, novel ideas or systems, late-breaking results, and prototypes relevant
to spatial interaction for virtual, augmented, mixed reality, as well as pervasive, intelligent/smart, and real environments.</div>
