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.

The visualization of spaces, both virtual and built, has long been an important part of the environment design process. Industry tools to visualize occupancy have grown from simple drop-in stock photos post-design to real-time crowds simulations. However, while treatment of visualization and collaborative design processes has long been discussed in the HCI and Architecture communities, these inclusive design methods are infrequently seen in architecture education (e.g. studio) and practice, nor implemented in licensure requirements - leaving designers to think about the future occupants on their own. While there are strong indicators of the impact visualization modality and rendering style have on perception of scale and space, little has been explored regarding how we represent the human form with respect to these design tools and practices. We present findings from a novel online interactive space planning and estimation study that examines the effects of 3 common building visualization modalities in the design process with 3 human form modalities extracted from the architecture literature. Results indicate the type of visualization changes the number of occupants estimated, and that designers prefer integrated manikins within building models when estimating space usage, although their acceptance was equally divided between 2D and 3D. Our findings lay the foundation for new and focused design tools integrating human form and factors at building scale.

This paper describes two exploratory and ongoing projects on data perception with the support of some preliminary experimental results. Firstly, the paper describes two approaches for haptic-based representation of multivariate data. Later, one of the approaches has been extended to help the blind students learn data structures in a multimodal environment.
The design of lighting in Computer graphics is directly derived from cinematography, and many digital artists follow the conventional wisdom on how lighting is set up to convey drama, appeal, or emotion. In this paper...
