We have observed subjective, physiological and behavioral reactions of subjects during a fully-immersive flight phobia experiment under two different conditions: the virtual flight environment was displayed immediately, or subjects visited a transitional environment before entering the virtual flight environment. We have quantified to what extent a gradual transition to the VE via a transitional environment increases the level of presence.

abstract = {General interest in visualizations of digital 3D cityscapes is growing rapidly, and several applications are already available that display such models very realistically. In order to generate a virtual 3D city model different approaches exist which use miscellaneous input data sources, for example, 2D maps, aerial images, or laser-scanned data. However, 3D landmarks which denote highly-complex and architecturally prominent buildings, e.g., churches, castles, spires etc., cannot be reproduced in an adequate manner by automatic reconstruction. Therefore, these entities are usually modeled manually by architectural offices or 3D design companies.

General interest in visualizations of digital 3D cityscapes is growing rapidly, and several applications are already available that display such models very realistically. In order to generate a virtual 3D city model different approaches exist which use miscellaneous input data sources, for example, 2D maps, aerial images, or laser-scanned data. However, 3D landmarks which denote highly-complex and architecturally prominent buildings, e.g., churches, castles, spires etc., cannot be reproduced in an adequate manner by automatic reconstruction. Therefore, these entities are usually modeled manually by architectural offices or 3D design companies.
