Improving 3D Visualizations: Exploring Spatial Interaction with Mobile Devices

3D data visualizations, while offering a lot of potential, have also well-known issues regarding occlusion and readability. Immersive technologies might help overcoming these issues by addressing the perceptional problems and increasing the tangibility of the data. In this work, we explore the potential of spatial interaction with mobile devices. Building on the related work and our own experiences, we report on visualizations that are fixed in space or fixed on the device, as well as combining them with head-coupled perspective. A number of prototypes we developed, helped us to gain practical insights in the possibilities and limitations of these techniques.
