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.

Perspective switch between first-person and aerial-views is an important and commonly executed task in navigation; and it is a special case in studying the effects of aging on navigational performance as well, because, reportedly, it is particularly harder for older people. In a controlled experiment, our participants learned a route in first-person view VE, and reproduced what they learned in an aerial-perspective view in immediate and delayed recall stages. To examine the effects of (and interactions between) multiple factors involved in the experiment in relation to the given task, we provide an in-depth investigation of group differences in spatial knowledge acquisition when a perspective switch is required based on age, mental rotation abilities, and visuospatial memory capacity with three VE designs that differ in levels of realism. Our findings based on the recall accuracy of 81 (42 younger, 39 older) participants in sketching tasks demonstrate significant differences across VE types, overall, in favor of our custom-designed VE in this demanding task. Furthermore, we demonstrate that age and visuospatial memory abilities are strong moderating factors, explicitly in this sketching task that requires a perspective switch, irrespective of VE types.

The sound of being there : Audiovisual cartography with immersive virtual environments / Florian Hruby in KN, Journal of Cartography and Geographic Information, vol 69 n° 1 (May 2019)  

Public [article]  inKN, Journal of Cartography and Geographic Information > vol 69 n° 1 (May 2019) . - pp 19 - 28 Titre : The sound of being there : Audiovisual cartography with immersive virtual environments Type de document : Article/Communication Auteurs : Florian Hruby, Auteur Année de publication : 2019 Article en page(s) : pp 19 - 28 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Termes descripteurs IGN] audiovisuel [Termes descripteurs IGN] environnement géographique virtuel [Termes descripteurs IGN] immersion [Termes descripteurs IGN] réalité virtuelle [Vedettes matières IGN] Géovisualisation Résumé : (Auteur) In recent years, immersion has become a frequently emphasized factor in the geovisualization research agenda. A principal reason for this growing interest is the assumption that immersive virtual environments (IVE) facilitate the formation of spatial presence, generally understood as the sense of “being there”. In a virtually mediated environment, the feeling of being there is of particular concern for cartographic ambitions, in terms of generating insights through geospatial representation. Current literature indicates that immersive VR systems stimulate the experience of spatial presence; however, this assumption is mainly based upon user studies in the visual communication channel. Moreover, research on IVE for geovisualization matters has to date been focused on visual-graphical rather than on auditive or even multisensory representations in virtual space. In this context, the present paper aims to evaluate the potential of audiovisual cartography with immersive virtual environments. Following a brief discussion of basic concepts, such as immersion, spatial presence and embodiment, we will integrate these aspects into a geovisualization immersion pipeline (GIP), as a framework with which to systematically link the technical and cognitive aspects of IVE. In the subsequent sections, we will examine this framework in the audio channel by analyzing how sound is implemented and perceived in GeoIVE. As we shall see, the positive effect of a combined audio-visual vs. exclusively visual presentation is supported by a series of user studies of sound effects, making audiovisual cartography with IVE a rich and worthwhile field of research.

Depth camera indoor mapping for 3D virtual radio play / Juho-Pekka Virtanen in Photogrammetric record, vol 33 n° 162 (June 2018)

In this paper, a virtual version of an audio installation in a historic building is produced, where the user freely explores the building and experiences a set of audio clips, creating a virtual radio play. A depth camera indoor mapping system, Matterport, captured a set of staged interiors. The aim was to evaluate the quality and usability of the indoor models and to demonstrate applying them in 3D application development. The quality of the models was evaluated by comparison with laser scanning, revealing limitations with Matterport: increasing the size of the measured area lowered the level of detail and accuracy of volumetric models. The quality of textures was not affected by this limitation, maintaining the appearance of models. To obtain optimised models for mobile 3D applications, a manual revision process was applied.

Learning effectiveness of virtual environments for 3D terrain interpretation and data acquisition / A.M. Perez-Romero in Survey review, vol 49 n° 355 (October 2017)

According to the experimental design, students received homogeneous training, followed by differential training, which divided the students into three statistically homogeneous groups where each group was subject to a different learning process: (1) virtual environment learning; (2) learning using physical scale models; and (3) a theoretical class. Afterwards, the students were evaluated using two tests under real field conditions. Results were obtained for the following study variables: field-test scores and whether or not the student was repeating the course. The students who learned using physical scale models obtained the best scores; their scores were significantly higher than those of students using virtual environment or a theoretical class. These findings open up new perspectives on the teaching of surveying with respect to other teaching methods.
