Enabling users to accurately perceive the correct depth of occluded objects is one of the major challenges in user interfaces for Mixed Reality (MR). Therefore, several visualizat...
Multi-touch displays are particularly attractive for collaborative work because multiple users can interact with applications simultaneously. However, unfettered access can lead t...
This paper introduces architectural and interaction patterns for integrating crowdsourced human contributions directly into user interfaces. We focus on writing and editing, compl...
