The manuscript is structured to include technology, design, and human factor perspectives. The text is visualization/display-focused, that is, other modalities such as audio, haptic, smell, and touch, while important for XR, are beyond the scope of this paper. We further narrow our focus to mainly geospatial research, with necessary deviations to other domains where these technologies are widely researched. The main objective of the study is to provide an overview of broader research challenges and directions in XR, especially in spatial sciences. Aside from the research challenges identified based on a comprehensive literature review, we provide case studies with original results from our own studies in each section as examples to demonstrate the relevance of the challenges in the current research. We believe that this paper will be of relevance to anyone who has scientific interest in extended reality, and/or uses these systems in their research.

Modeling evacuation in institutional space: Linking three-dimensional data capture, simulation, analysis, and visualization workflows for risk assessment and communication / Ian M. Lochhead in Information visualization, vol 18 n° 1 (January 2019)

We present a collection of geovisual analytical environments that were developed to permit new ways to view and assess risk, evacuation, and human movement. Part of this research considers how different approaches to the representation of complex institutional space, using three-dimensional capture technologies at multiple resolutions (or derived from conventional formats, such as building plans), have implicit advantages or liabilities in the analysis of risk and human evacuation. We combine three-dimensional data capture methods with geographical information science theory, three-dimensional game engines, three-dimensional evacuation simulations and spatial analyses that address the variability of campus populations, and draw upon three-dimensional modeling and photogrammetry for the assessment of real-world features in digital space. The outcome of this research demonstrates agile workflows that address emergency planning requirements, but could also enable enhanced visual analysis and interactive learning by all campus citizens. Furthermore, this work reveals key considerations and limitations associated with the dynamic nature of evacuation events and the static environments in which they have been simulated.

Flexible mixed reality and situated simulation as emerging forms of Geovisualization / Chris Lonergan in Cartographica, vol 49 n° 3 (September 2014)

The authors summarize previous work that has led to a critical convergence of enabling technologies and identify new forms of geovisualization facilitated by these technologies. The article introduces situated simulation as a new form of augmented situated geovisual analysis, using two versions of a prototype system called A Touch of Rain. This system allows users to run augmented precipitation simulations in real space, in which virtual rain falls on and interacts with real landscapes and buildings, and thus to perform augmented geovisual analysis. This method opens up new opportunities to link geospatial data, models, and everyday spaces. The authors conclude by discussing implications and opportunities for GIScience.

Virtual and augmented reality interfaces: empirical findings and implications for spatial visualization / Nick Hedley (2001)  

Public contenu dans Mapping the 21st century: the 20th International Cartographic Conference, ICC 2001, Beijing, China, August 6 - 10, 2001, vol 4. Proceedings / L. Li (2001)   Titre : Virtual and augmented reality interfaces: empirical findings and implications for spatial visualization Type de document : Article/Communication Auteurs : Nick Hedley, Auteur Editeur : International Cartographic Association ICA - Association cartographique internationale ACI Année de publication : 2001 Conférence : ICC 2001, 20th International Cartographic Conference ICA, Mapping the 21th century 06/08/2001 10/08/2001 Pékin Chine OA Proceedings Importance : pp 2606 - 2613 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique [Termes IGN] données localisées [Termes IGN] interface utilisateur [Termes IGN] réalité augmentée [Termes IGN] réalité virtuelle [Termes IGN] visualisation 3D Résumé : (Auteur) This is an exciting and challenging time for researchers of visualization and spatial knowledge integration. We are at a new frontier in geographic visualization research. Recent technological development has produced tools and techniques that change the nature of geographic visualization significantly, especially interfaces, interactions and metaphors. It is essential that the field of geographic visualization understand these technologies, and more importantly, understand their relationship with people and the knowledge that results from interactions with them. New spatial visualization technologies are emerging that fundamentally change the nature of interaction and spatial knowledge acquisition from visualizations. Virtual Environments (VE) allow users to explore spatial information using a diverse range of visualization artifacts, interaction modalities and control devices. Experiences in such environments can be powerful. However, like interfaces, every VE provides a unique set of affordances and inherent limitations for visualization a interaction. New interface technologies are emerging that are flexible, portable and more readily combined with everyday practice than existing semi- and fully-immersive VE technologies. Augmented Reality (AR) an emergent technology which enhances real-world settings with virtual objects. The resulting systems provide compelling visualization and interaction experiences that are easily integrated with day-to-day practice. These characteristics have significant potential as future spatial visualization systems. This paper presents key issues and challenges in geographic visualization interfaces using virtual environments with a focus on Augmented Reality. The past two years of research has led to the design and implementation of several virtual environments for spatial visualization, including a fully-immersive VE, and several Augmented Reality visualization systems that allow both non-immersion and full immersion. A sequence of user experiments was undertaken to study mental model formation, conceptual change and behavioral interactions with these interface technologies. Empirical and anecdotal findings are presented from the development and testing of these interfaces. The implications and significance of these findings for geographic visualization and cartographic practice are discussed. Future prospects are discussed and research directions are proposed. This work identifies key issues to guide future spatial visualization interface design and development, and to maximize the potential of these new technologies.
