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)
Immersive virtual environments can break the deep, everyday connection between where our senses tell us we are and where we are actually located and whom we are with. The concept of 'presence' refers to the phenomenon of behaving and feeling as if we are in the virtual world created by computer displays. In this article, we argue that presence is worthy of(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)

In this paper, I address the question as to why participants tend to respond realistically to situations and events portrayed within an immersive virtual reality system. The idea is put forward, based on the experience of a large number of experimental studies, that there are two orthogonal components that contribute to this realistic response. The first is(More)
This note addresses the confounding of the term 'presence' with several different distinct aspects of experience. Distinctions should be made between immersion, presence, involvement, emotional response, degree of interest. An analogy with colour science is pursued, specifically the difference between wavelength distribution and perception of colour-where(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)
A b st ra ct This paper describes a new measure for presence in immersive virtual environments (VEs) that is based on data that can be unobtrusively obtained during the course of a VE experience. At different times during an experience, a participant will occasionally switch between interpreting the totality of sensory inputs as forming the VE or the real(More)
We describe an experiment to assess the influence of body movements on presence in a virtual environment. In the experiment 20 participants were to walk through a virtual field of trees and count the trees with diseased leaves. A 2 x 2 between subjects design was used to assess the influence of two factors on presence: tree height variation and task(More)
