Realism in Virtual Reality

In this paper we want to present the state-of-the-art in providing realism in virtual environments. Techniques will be discussed to increase visual and auditory presentation. The behaviour of virtual worlds - a further demand on realism - is introduced and interaction techniques are explained with regard to intuitive understanding. Finally, we explain some applications in virtual environments which aim for a high degree of realism. As a conclusion we try to point out that realism (or a realistic impression) is subjective and heavily depending on the user himself.
