Hybrid Tactile/Tangible Interaction for 3D Data Exploration

“…Good examples of this approach are Jorda et al's [40] prototype for live music performance as well as Al-Megren and Ruddle's [1] setup for abstract data analysis. An example of such a combination for spatial 3D visualization is Sultanum et al's [69] table-based system for exploring geologic reservoir data. They use tangible props for detailed data read-out and parameterizing a focus+context view, while tactile input is used for regular data navigation as well as for dedicated exploration techniques such as dataset splitting and layer peeling.…”

“…We were interested in their general opinion about such a hybrid interaction style, their understanding of the mappings, the way they transition between different modalities, how well the chosen mappings support their data exploration goals, and how they made use of those interaction capabilities in practice. We used an observational strategy like several visualization researchers before us (e. g., [19,44,48,49,69]). We specifically decided against a classical usability study for several reasons.…”

“…While several mappings for the two paradigms have been explored in the past [54,69], their respective benefits and challenges with respect to 3D data exploration remain uncertain. We thus investigate their integration in one device and the resulting possibilities and potential interaction mappings for common 3D data exploration tasks.…”

A Design Study of Direct‐Touch Interaction for Exploratory 3D Scientific Visualization

“…Both the domain-specific setups and also the data-driven approaches pay attention to the ability to combine different interaction techniques in such a way that they can be employed in the same interaction space, an aspect that is also essential in our approach. Mode switching is often enabled using postures, while Sultanum et al [SSSS11] also use tangibles and Lundström et al [LRF * 11] virtual objects for the same purpose. Some techniques essential in visualizationbeyond our 'normal' navigation and zooming [YSI * 10]have been studied before.…”

“…Some techniques essential in visualizationbeyond our 'normal' navigation and zooming [YSI * 10]have been studied before. For example, cutting [SSSS11] and cutting planes [CML * 11], probing [SSSS11], particle placement [BW11], and combinations of 2D and 3D interaction [CML * 11] have previously been discussed individually. Our application domain of fluid mechanics, however, like many other visualization fields requires all of these and other techniques to be accessible, while some (e. g., cutting planes) also need to be controllable with more DOF.…”
