People experience different levels of presence (e.g. Krijn et al., 2004; Walshe, Lewis, Kim, O'Sullivan, & Wiederhold, 2003), and different levels of cybersickness (Sharples, Cobb, Moody, & Wilson, 2008) even though they are immersed in the same virtual environment setting. In the current study, we raised the question how differences in individual characteristics might relate to differences in ...

Future applications of virtual reality will require increasingly complicated virtual worlds to yield the richness and functionality demanded by increasing numbers of users. This document introduces some qualitative measures of complexity which may be used to asses virtual reality systems. A number of current virtual reality systems are considered with regard to the facilities and complexity whi...

The current article approaches interaction between architecture and machine in one of its several dimensions, namely computer technology and virtual reality. We begin with an introduction to complexity sciences and continue with a brief description of Systems Theory and Cybernetics, leading to the notion of virtual reality and cyberspace. The approach to the virtual architecture presented in th...

This paper addresses the problems associated with interaction in immersive virtual reality and makes recommendations as to how best to deal with these problems, thereby producing a usable virtual reality interactive environment. Immersive virtual reality means that the users are immersed or contained inside the environment in which they are working. For example, they are able to turn their head...

This paper proposes the concept of “liveaction virtual reality games” as a new genre of digital games based on an innovative combination of live-action, mixed-reality, context-awareness, and interaction paradigms that comprise tangible objects, context-aware input devices, and embedded/embodied interactions. Live-action virtual reality games are “live-action games” because a player physically a...
