My research explores how collaboration can be supported and promoted in multi-user immersive analytics environments. A key area of focus is how the intangibility of virtual/holographic objects can be leveraged to provide truly private work spaces, which may eliminate common issues such as distractions and occlusion. These objects can then be subsequently shared in order to present findings and facilitate discussion. The manner in which this sharing is performed may potentially take on many forms, ranging from real-life metaphors (e.g. shared tabletops) to more "magical" interaction methods (e.g. 3D widgets).
