Virtual Reality Technology - An Overview

Enhancing the effectiveness of design tools in synthetic environments

“…This definition highlights the relation with reality, which is essential for VR in the field of product development. Furthermore, the three main characteristics (experience, modification and interaction) are mentioned and the different characterisations by Blach are observed (Blach, 2008).…”

“…These VR systems can form a complex combination of possibilities and limitations. To understand the different characteristics of a VR system, and to gain insight in specifications, to following classification of elements can be used (Blach, 2008):…”

“…• Content dynamics: A VR application can respond to the input of the user; the reactivity and to what extent the user can change the virtual environment are described here. (Blach, 2008) states that a VR system needs to be composed of three components: hardware, software, and applications. The hardware used in VR applications can roughly be divided into visual displays, tracking devices, auditory feedback, and haptic feedback.…”

“…The term 'Virtual Reality' is often used as a comprehensive term for all forms of mixed reality. Blach describes virtual environments as a range of embedding computer mediation in reality (Blach, 2008), based on the mixed reality continuum of Milgram (Milgram, Takemura et al, 1995) (figure 2.7).…”

“…The virtual representation of the world offers opportunities for alternation, and provides reaction on the (calculated) consequences. This (Blach, 2008) 2 approach, which is the basis for many VR simulators, makes it easier to perform iterations in a PDP. The effort needed to make an iteration can be minimised by preventing physical models, and the consequences of the iteration can be directly reviewed from multiple perspectives.…”
