Towards Optimizing Spatial Perception of Embedded-Object Visualizations in Optical See-Through Mixed Reality

In this poster, we present work-in-progress research towards improving the spatial perception of 3D objects on Optical See-through Mixed Reality displays, addressing, in particular, visualizations comprising virtual objects embedded inside physical real-world objects. This use-case is common in visualization applications in medicine, engineering and geosciences, but is an added challenge in mixed reality (MR), where multiple modalities of data (real and virtual objects) essentially occupy the same 3D space leading to inevitable depth ambiguity. In this poster, we review several strategies for ameliorating this problem, discuss insights from preliminary implementations of such approaches and propose avenues for future work.
