Do virtual worlds create better real worlds?

Real Mirrors Reflecting Virtual Worlds

This paper introduces the idea of using real mirrors in combination with rear-projection systems for the purpose of interacting with and navigating through the displayed information. Subsequently a derived application is described. For this, we use a hand-held planar mirror and address two fundamental problems of applying head tracking with rear-projection planes: the limited viewing volume of ...

Real Worlds, Virtual Worlds – and the Roots of Psychoacoustics

Knowledge from Psychoacoustics has recently gained increasing attention in technology. In this context it can be observed that, on the one hand, scientific Psychoacoustics is overestimated regarding it's application potency and, thus, contributions are expected from it which it cannot render. On the other hand, Psychoacoustics is also underestimated in that it is considered to be primarily “sub...

Handling Interactions Between Real And Virtual Worlds

When compositing computer generated images and photographs or video images, interactions between real and virtual worlds must be taken into account in order to have a good visual result. These interactions are of three kinds: occluding object determination, specular inter-reflection and shadow computation. We first determine which real objects need to be geometrically and/or photometrically mod...
