“…Over time, many articles and journals defined presence differently, but all had a similar general meaning. In this research paper, the main definition of presence that will be used is the awareness or state of the mind of being in an environment, either real or virtual (Usoh et al, 1999;Nunez & Blake, 2001). Experiencing a sense of presence can happen whenever a person mentally feels that he or she is present in a situation.…”

User experience is a critical component in the development of virtual environment systems and applications. To create an effective and efficient user experience for virtual environment systems, it is imperative to conduct empirical studies to explore factors that contribute to a heightened sense of presence, or immersion, for users, who increasingly demand an experience in a virtual environment that seems as real as possible. The primary hypothesis of this study is that participants will experience higher levels of presence in an Immersive Visualization Environment (IVE) than in a Traditional Virtual Reality Environment (TVRE). The empirical methodology consists of two different experiments designed, developed, and implemented using seventy participants. A simulated virtual airplane scenario was created and conducted for each participant. After completion of each simulation session, each participant was given a questionnaire that measured the participant's sense of presence in either virtual or real environments. Analysis of the collected data indicated that there was a statistically significant difference in the level of presence experienced by participants between the TVRE and IVE systems. The primary conclusion is that participants experienced a higher sense of presence in the IVE experiment when compared with the TVRE experiment, indicating significantly more natural and richer user experience through the IVE system's interface.

“…A virtual reality (VR) environment, however, is suitable for such circumstances. Virtual environments that can generate a high degree of presence are thought to be more effective and better suited to task performance (Slater 1994;Nunez and Blake 2001).…”

Abstract. This project intends to develop a method for using virtual reality (VR) to represent a built environment for simulating environmental influences on occupants. Objectives of the project were to explore: (1) what environmental stimuli would affect habitants' perception, and (2) what possible factors in the built environment would affect occupants' cognition. An office was selected as the subject of study. Methods were to create a number of digital models, each containing an embedded variable, and then test the impact of environmental influences on visual perception. Results obtained in this study indicate that materials have stronger impact to human perception than colors, and VR has great potential for design decision making and post-occupancy evaluation.

“…Because models use quite different theoretical bases, there is often little common ground for comparisons or discussion between authors. Recently, there has been a move towards using cognitive psychology and perception theory as a basis for presence research (see [8] and [9] for examples of this trend). Our work follows this trend by beginning from the concept of cognitive presence [9] which emphasizes the role of perception and the subsequent selection of environmentally appropriate behaviours in virtual environments.…”

“…We conducted an experiment to investigate the effects of higher-level cognitive processes (by means of schemata activation) on presence, and how these conceptual variables interact with the fidelity of sensory stimuli. Based on the reasoning presented in 1.2 above, and on the definition of cognitive presence [9] we assume that schemata are involved in the cognitive processing of environments, and therefore in presence. Our aim was to test the following two hypotheses and the associated interaction effect:…”

Many presence studies show the importance of display variables in determining presence. However, very little empirical evidence exists to support the notion of "the suspension of disbelief" or other psychological determinants of presence. We argue from a cognitive presence perspective that presence can be considered as an extension of perception, a process which is known to be significantly affected by the perceiver's mental state. We support our argument by presenting the results of a large study (n=103) in which users were conceptually primed by reading a booklet either related to or unrelated to a VE and then were left to explore that VE with either a high quality or low quality display. We found a significant interaction effect between display quality and priming, showing that the mental state of the user sets a context which affects their experience of presence as measured using two scales. We conclude that, like perception, presence does not simply occur as a consequence of sensory input only, but that it is a constructive process in which the VE user creates an experience using both sensory and psychological inputs.
