This paper reports on the effect of 3D architectural visualization in VR and its possible effect on the sense of presence. The problem definition was tested by use of a between subjects design. Two groups were randomly formed. One group evaluated the 3D visualized virtual environment, and the other the 2D visualized virtual environment. Afterwards the Igroup Presence Questionnaire was used to evaluate the sense of presence. This questionnaire covers three subscales (spatial presence, involvement, and experienced realism) and one additional general item (“sense of being there”) not belonging to a subscale. Two out of three subscales showed a significant improvement of the 3D visualized virtual environment. Involvement and the general item showed no significant difference. It is evident that the 3D architectural visualization provides us with a promising perceptual component for reaching a higher sense of presence for VR exposure therapy.
