Abstract
In this paper, we introduce the concept of Extended VR (extending viewing space and interaction space of back‐projection VR systems), by describing the use of a hand‐held semi‐transparent mirror to support augmented reality tasks with back‐projection systems. This setup overcomes the problem of occlusion of virtual objects by real ones linked with such display systems. The presented approach allows an intuitive and effective application of immersive or semi‐immersive virtual reality tasks and interaction techniques to an augmented surrounding space. Thereby, we use the tracked mirror as an interactive image‐plane that merges the reflected graphics, which are displayed on the projection plane, with the transmitted image of the real environment. In our implementation, we also address traditional augmented reality problems, such as real‐object registration and virtual‐object occlusion. The presentation is complemented by a hypothesis of conceivable further setups that apply transflective surfaces to support an Extended VR environment.
