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. ZusammenfassungVirtuelle Realität (VR) und Immersion haben sich in den vergangenen Jahren auf der Forschungsagenda der Kartographie fest etabliert. Ein Hauptgrund dieses wachsenden Interesses ist die Annahme, dass immersive virtuelle Umgebungen räumliches Präsenzerleben induzieren, so dass sich Rezipient/inn/en in einer medialen Umgebung anwesend fühlen und Handlungsmöglichkeiten innerhalb derselben wahrnehmen. Für das grundsätzliche Ziel der Kartographie, raumbezogenes Wissen durch Repräsentationen zu vermitteln, ist das Phänomen räumlichen Präsenzerlebens von besonderem Interesse. Rezente Studien weisen zwar darauf hin, dass immersive VR-Systeme ein hohes Präsenzerleben erzeugen können, stützen sich dabei jedoch in erster Linie auf Untersuchungen des visuellen Kommunikationskanals. Ebenso hat sich die kartographische Erforschung immersiver Umgebungen bislang vor allem visuellen bzw. graphischen, weniger aber auditiven und multisensorischen Repräsentationsformen gewidmet. Vor diesem Hintergrund versucht der vorliegende Text, das Potenzial einer audiovisuellen Kartographie in immersiven virtuellen Umgebungen zu bewerten. Der einleitenden Diskussion zentraler Termini (z.B. Immersion, räumliches Präsenzerleben, Embodiment) folgt eine Verknüpfung dieser Schlüsselbegriffe innerhalb einer kartographischen Immersionspipeline -eine Modellvorstellung, die technische und kognitive Aspekte imme...

“…However, the rating increases for the SV4 case, where visual matches sounds. This could be explained -to some extent -by the congruency hypothesis (Ge & Hokao, 2005;Lindquist, Lange, & Kang, 2016). The large reduction in level provided by a strong visual barrier matches people's expectations, positively affecting general pleasantness.…”

ABSTRACT:Sound planning is not often included in the urban design process despite the well-known audio-visual interactions of human perception. A methodology to compare the overall appreciation of future renovation alternatives of urban public spaces using Virtual Reality Technology is proposed. This method is applied to assess the role of noise in the overall appreciation of a walk on a bridge crossing a highway. The auralization is a dynamic 3D surround based on B-format recordings (ambisonics), filtered by means of full-wave numerical calculations obtaining the sound field behind noise barriers along the bridge's edge. Four different styles of visual street design including different noise barrier heights in combination with the 4 corresponding predicted sound fields were evaluated for their pleasantness by 71 normal-hearing participants on 4 separate days. Each day participants experienced all the visual environments with only one soundscape (to elude direct sound comparison) and anything related to sound was not mentioned in the first part of the experiment. Even in this non-focussed context, a statistically significant effect of the sound environment on the overall appreciation was found. In general, the pleasantness increases with traffic noise level reduction, but the visual design has a stronger impact. By mentioning the soundscape while introducing the evaluation, slightly lower (but statistically significantly different) pleasantness ratings were obtained. Instead of increasing noise barrier height, improving the visual design of a lower barrier seems more effective to increase pleasantness.Visual designs including vegetation strongly outperform others. The virtual experience was rated as immersive and realistic.3

Human actions in the natural environment create a visual impact. The main objective of this study was to examine the acceptance of vegetation screens for integrating buildings into the landscape using new techniques of visualization in three dimensions (3D), videos and public participation. The status quo of two study areas representative of the Mediterranean climate in Spain (one inland and one coastal) was modelled, placing vegetation screens around a building typical of the area and varying the density, species, and layout of plants. After establishing a series of scenarios, videos showing a simulation of outdoor tourism activities performed at varying speeds were created to analyse how movement affects the perception of the combination of a building and vegetation screen in the versions created. The 3D models generated were subjected to a survey for public participation and to allow respondents to rate their preferences of the videos created. The results show that adding vegetation always improves the integration of buildings into the landscape. The most highly rated vegetation screen placed around the buildings in the two scenarios was high density vegetation, irrespective of the layout or species.
