- ItemOpen AccessBeyond the Physical: Examining Scale and Annotation in Virtual Reality Visualizations(Department of Computer Science, University of Calgary, 2018-10-10) Ulusoy, Teoman; Danyluk, Kurtis Thorvald; Willett, Wesley J.We examine how viewers in virtual reality (VR) environments interact with simple data visualizations at scales ranging from hand-sized to room-sized. We also explore how the addition of virtual annotation and filtering tools affects how viewers solve basic data analysis tasks. We report on two studies, inspired by previous examinations of data physicalizations. The first study investigated how three visualization sizes, including hand-, table , and room-scale versions, impact viewers’ problem-solving behavior. A second study examined how interactive annotation and filtering tools might support new modes of use that transcend the limitations of physical representations. Our results highlight challenges associated with extreme scales, especially those that require navigation techniques other than physical locomotion, and hint at the potential of interactive annotation and filtering tools in VR visualization environments.
- ItemOpen AccessA Design Space Exploration of Worlds in Miniature(ACM : New York, New York, 2021-05-08) Danyluk, Kurtis Thorvald; Ens, Barrett; Jenny, Bernhard; Willett, Wesley J.Worlds-in-Miniature (WiMs) are interactive worlds within a world and combine the advantages of an input space, a cartographic map, and an overview+detail interface. They have been used across the extended virtuality spectrum for a variety of applications. Building on an analysis of examples of WiMs from the research literature we contribute a design space for WiMs based on seven design dimensions. Further, we expand upon existing definitions of WiMs to provide a definition that applies across the extended reality spectrum. We identify the design dimensions of size-scope-scale, abstraction, geometry, reference frame, links, multiples, and virtuality. Using our framework we describe existing Worlds-in-Miniature from the research literature and reveal unexplored research areas. Finally, we generate new examples of WiMs using our framework to fill some of these gaps. With our findings, we identify opportunities that can guide future research into WiMs.
- ItemOpen AccessExploration & Anthropomorphism in Immersive Unit Visualizations(ACM: Extended Abstracts of the 2018 CHI Conference on Human Factors in Computing Systems, 2018-04-20) Ivanov, Alexander; Danyluk, Kurtis Thorvald; Willett, WesleyWe report on an initial examination of the potential of immersive unit visualizations in virtual reality, showing how these visualizations can help viewers examine data at multiple scales and support affective, personal experiences with data. We outline unique opportunities for unit visualizations in virtual reality, including support for (1) dynamic scale transitions, (2) immersive exploration, and (3) anthropomorphic interactions. We then demonstrate a prototype system and discuss the potential for virtual reality visualization to support personal interactions with data.
- ItemOpen AccessLook-From Camera Control for 3D Terrain Maps(Association for Computing Machinery, 2018-10) Danyluk, Kurtis Thorvald; Jenny, Bernhard; Willett, Wesley J.We introduce three lightweight interactive camera control techniques for 3D terrain maps on touch devices based on a look-from metaphor (Discrete Look-From-At, Continuous Look- From-Forward, and Continuous Look-From-Towards). These techniques complement traditional touch screen pan, zoom, rotate, and pitch controls and allow viewers to quickly transition between top-down, oblique, and ground-level views. We present the results of a study in which we asked participants to perform elevation comparison and line-of-sight determination tasks using each technique. Our results highlight how look-fromtechniques can be integrated on top of current direct manipulation navigation approaches by combining several direct manipulation operations into a single look-from operation. Additionally, they show how look-from techniques help viewers complete a variety of common and challenging map-based tasks.
- ItemOpen AccessTouch and Beyond: Comparing Physical and Virtual Reality Visualizations(2020-09-10) Danyluk, Kurtis Thorvald; Ulusoy, Teoman Tomo; Wei, Wei; Willett, Wesley J.We compare physical and virtual reality (VR) versions of simple data visualizations. We also explore how the addition of virtual annotation and filtering tools affects how viewers solve basic data analysis tasks. We report on two studies, inspired by previous examinations of data physicalizations. The first study examined differences in how viewers interact with physical hand-scale, virtual hand-scale,and virtual table-scale visualizations and the impact that the different forms had on viewer's problem-solving behavior. A second study examined how interactive annotation and filtering tools might support new modes of use that transcend the limitations of physical representations. Our results highlight challenges associated with virtual reality representations and hint at the potential of interactive annotation and filtering tools in VR visualizations.
