This article presents an interactive technique for moving through an immersive virtual environment (or “virtual reality”). The technique is suitable for applications where locomotion is restricted to ground level. The technique is derived from the idea that presence in virtual environments may be enhanced the stronger the match between(More)
Witmer and Singer recently published a questionnaire for eliciting presence in virtual environments together with a questionnaire for measuring a person's immersive tendencies (Witmer & Singer, 1998). The authors mentioned that they did not agree with my notion of immersion: 'Though the VE equipment is instrumental in enabling immersion, we do not agree(More)
A study by Slater, et al., [1995] indicated that naive subjects in an immersive virtual environment experience a higher subjective sense of presence when they locomote by walking-in-place (virtual walking) than when they pushbutton fly (along the floor plane). We replicated their study, adding real walking as a third condition. Our study confirmed their(More)
Investigating virtual environments has become an increasingly interesting research topic for engineers, computer and cognitive scientists, and psychologists. Although there have been several recent studies focused on the development of multimodal virtual environments (VEs) to study human-machine interactions, less attention has been paid to human-human and(More)
This paper describes an experiment that compares behaviour in small groups when they carry out a task in a virtual environment (VE) and then continue the same task in a similar real-world environment. The purpose of the experiment was not to examine task performance, but to compare various aspects of the social relations between the group members in the two(More)
" We modern, civilised, indoors adults are so accustomed to looking at a page or a picture, or through a window, that we often lose the feeling of being surrounded by the environment, our sense of the ambient array of light... We live boxed up lives. Abstract This paper reviews the concepts of immersion and presence in virtual environments. We propose that(More)
The integration of the human brain with computers is an interesting new area of applied neuroscience, where one application is replacement of a person's real body by a virtual representation. Here we demonstrate that a virtual limb can be made to feel part of your body if appropriate multisensory correlations are provided. We report an illusion that is(More)
This paper describes an experiment to assess the anxiety responses of people giving five minute presentations to virtual audiences consisting of eight male avatars. There were three different types of audience behaviour-an emotionally neutral audience that remained static throughout the talk, a positive audience which exhibited friendly and appreciative(More)
