Using numerous studies from virtual reality, 3D cinema, and video games, Daniel Pietschmann analyzes key implications for the combination of realistic input devices and stereoscopic displays in experiencing modern virtual environments. These technologies provide perception-based sensory stimuli that are examined within the context of spatial mapping. The focus is on the integration of various input and output technologies along with the associated interaction objects. A high degree of spatial mapping allows users to intuitively interact with virtual spaces, as the perceptual spaces are ideally aligned with each other. The transfer of knowledge and skills from real to virtual actions leads to a positive user experience and improved task performance. The author discusses the application of spatial mapping depending on the I.
