We examined touch-based navigation of 3D visualizations in a combined monoscopic and stereoscopic viewing environment [32] (see Figure 8 ). We identified a set of interaction modes, and a workflow that helps users transition between these modes to improve their interaction experience. For this purpose we analyzed, in particular, the control-display space mapping between the different reference frames of the stereoscopic and monoscopic displays. We showed how this mapping supports interactive data exploration, but may also lead to conflicts between the stereoscopic and monoscopic views due to users’ movement in space; we resolved these problems through synchronization. To support our discussion, we conducted an exploratory observational evaluation with domain experts in fluid mechanics and structural biology. These experts explored domain-specific datasets using variations of a system that embodies the interaction modes and workflows; we could report on their interactions and qualitative feedback on the system and its workflow.
