Abstract

In this article I provide from localization experiments in virtual environment. I define common tasks (orientation, localization, and navigation) in immersive visualization. The above mentioned tasks will be examined with user tests. Two localization experiments have been accomplished. In the first localization experiment the localization accuracy was significantly better (p<<0.01 in ANOVA) with loudspeaker reproduction than with headphone reproduction (nonindividualized HRTF's). The second experiment indicated, that localization accuracy is depending on signal (P<<0.01 in ANOVA). Although the absolute lower limit for auditory localization accuracy in front is one degree for the azimuth, the reality is much worse. For example the screens and room reverberation deteriorate loudspeaker reproduction accuracy. Current results suggest that at least in some tasks the audio is useful addition to immersive visualization tasks.
