Communities identify and are identified by not just the clothes they wear or by the language they speak, or even by the way they greet each other. Communities are often identified by where their activities take place, how they use spaces to construct meanings, and the traces left by their social interactions. These “trigger” regions are thus not just points in space; they are also landmarks, havens, homes, ruins, or hells. Communities, then, are identified and identify with or against, not just space but place. For places do not just organize space; they orient, identity, and animate the bodies, minds, and feelings of both inhabitants and visitors. Presence researchers have often cited and used, the sense of “being in a place” as a test of virtual presence. For example, Biocca (1997) says people feel present in real imaginary or virtual places. Slater (1999) says one aspect of presence is feeling that one is in another place, and not just viewing a set of images. Researchers often use the term “place” in their presence questionnaires (Lessiter, Freeman, Keogh, & Davidoff, 2000; Schuemie, van der Straaten, Krijn, & van der Mast, 2001; Slater, 1999). While much debate has centered on the meaning of virtual “presence,” there has been far less debate on a virtual “place.” Presence in virtual environments is often defined as the subjective belief that one is in a place even though the participant knows the experience is mediated by digital media (Slater, 1999). Yet presence can only be clearly defined when relating it to place, if place itself is clearly defined and understood. Place itself may mean many different types of location, the feeling that one is in or surrounded by a type or kind of location, or the intensity of that feeling of being in a particular place. One may well feel spatially surrounded, or be able to say an event happened in a certain position in a virtual environment without feeling that one was experiencing a strong or unique experience of place. To understand how and why people can feel a sense of presence then, we need to have a clear and appropriate sense of place. And if we do not have a strong sense of place, then perhaps we do not have a strong sense of presence. Many writers (frequently from architecture) have made the distinction between place and cyberspace, and suggested that virtual environments usually lack the former (e.g., Benedikt, 1991; Champion & Dave, 2002; Coyne, 1999; Johnson, 1997; Kalay & Marx, 2001, 2003; Kitchin, 1998). Given the premise that place is a necessary part of creating a meaningful virtual environment, the question is raised as to how we can best gain a sense of place via virtual environments.

This work focus on the study of solutions that using video 360 and virtual reality that allow children’s and older people that are away of their family environments for various reasons to be able to feel they are participating at family or school events. The solutions proposed should deliver a strong sense of presence to the users and the interface must be friendly. The validation will be made by user observation and inquiries.

This paper reports the results of three studies, each of which investigated the sense of presence within virtual environments as a function of visual display parameters. These factors included the presence or absence of head tracking, the presence or absence of stereoscopic cues, and the geometric field of view used to create the visual image projected on the visual display. In each study, subjects navigated a virtual environment and completed a questionnaire designed to ascertain the level of presence experienced by the participant within the virtual world. Specifically, two aspects of presence were evaluated: (1) the sense of “being there” and (2) the fidelity of the interaction between the virtual environment participant and the virtual world. Not surprisingly, the results of the first and second study indicated that the reported level of presence was significantly higher when head tracking and stereoscopic cues were provided. The results from the third study showed that the geometric field of view used to design the visual display highly influenced the reported level of presence, with more presence associated with a 50 and 90° geometric field of view when compared to a narrower 10° geometric field of view. The results also indicated a significant positive correlation between the reported level of presence and the fidelity of the interaction between the virtual environment participant and the virtual world. Finally, it was shown that the survey questions evaluating several aspects of presence produced reliable responses across questions and studies, indicating that the questionnaire is a useful tool when evaluating presence in virtual environments.

Two studies were performed to investigate the sense of presence within stereoscopic virtual environments as a function of the addition or absence of auditory cues. The first study examined the presence or absence of spatialized sound, while the second study compared the use of nonspatialized sound to spatialized sound. Sixteen subjects were allowed to navigate freely throughout several virtual environments and for each virtual environment, their level of presence, the virtual world realism, and interactivity between the participant and virtual environment were evaluated using survey questions. The results indicated that the addition of spatialized sound significantly increased the sense of presence but not the realism of the virtual environment. Despite this outcome, the addition of a spatialized sound source significantly increased the realism with which the subjects interacted with the sound source, and significantly increased the sense that sounds emanated from specific locations within the virtual environment. The results suggest that, in the context of a navigation task, while presence in virtual environments can be improved by the addition of auditory cues, the perceived realism of a virtual environment may be influenced more by changes in the visual rather than auditory display media. Implications of these results for presence within auditory virtual environments are discussed.

Virtual reality environments are increasingly being used to encourage individuals to exercise more regularly, including as part of treatment those with mental health or neurological disorders. The success of virtual environments likely depends on whether a sense of presence can be established, where participants become fully immersed in the virtual environment. Exposure to virtual environments is associated with physiological responses, including cortical activation changes. Whether the addition of a real exercise within a virtual environment alters sense of presence perception, or the accompanying physiological changes, is not known. In a randomized and controlled study design, moderate-intensity Exercise (i.e., self-paced cycling) and No-Exercise (i.e., automatic propulsion) trials were performed within three levels of virtual environment exposure. Each trial was 5 minutes in duration and was followed by posttrial assessments of heart rate, perceived sense of presence, EEG, and mental state. Changes in psychological strain and physical state were generally mirrored by neural activation patterns. Furthermore, these changes indicated that exercise augments the demands of virtual environment exposures and this likely contributed to an enhanced sense of presence.

It has long been argued that the possibility to interact in and with a virtual environment (VE) enhances the sense of presence. On the basis of a three-component model of presence, we specify this hypothesis and argue that the mental representation of possible actions should especially enhance spatial presence, and to a lesser extent the involvement and realness of a VE. We support this hypothesis in three studies. A correlative study showed that self-reported interaction possibilities correlated significantly with spatial presence, but not with the other two factors. A first experimental study showed that possible self-movement significantly increased spatial presence and realness. A second experimental study showed that even the illusion of interaction, with no actual interaction taking place, significantly increased spatial presence.

A text-based networked virtual environment represents to a user a system of rooms joined by exits and entrances. When navigating this system of rooms, a user can communicate in real time with other connected users occupying the same room. Hence, these virtual environments are aptly suited for networked conferencing and teaching. Anecdotal information suggested that some people feel a sense of “being there” or presence when connected to one of these environments. To determine how many people feel this sense of presence, we surveyed 207 people from 6 different groups of users of text-based networked virtual environments. The results indicated that 69% of these subjects felt a sense of presence. Experiments with people in text-based networked virtual environments may be helpful in understanding the contribution to presence by social interaction in other virtual environments.

Outdoor virtual environments (OVEs) are becoming increasingly popular, as they allow a sense of presence in places that are inaccessible or protected from human intervention. These virtual environments (VEs) need to address physical modalities other than vision and hearing. We analyze the influence of four different physical modalities (vision, hearing, haptics, and olfaction) on the sense of presence on a virtual journey through the sea and the Laurissilva Forest of Funchal, Portugal. We applied Slater et al.'s (2010) method together with data gathered by the Emotiv EPOC EEG in an OVE setting. In such a setting, the combination of haptics and hearing are more important than the typical virtual environment (vision and hearing) in terms of place and plausibility illusions. Our analysis is particularly important for designers interested in crafting similar VEs because we classify different physical modalities according to their importance in enhancing presence.

The study of sense of presence experienced in virtual reality environments has become an important area of research. The continued advancement of immersive technology offers more opportunities to examine how a subject becomes immersed in and interacts with a variety of virtual environments. The primary purpose of this research is to study the sense of presence while interacting with a traditional Virtual Reality Environment (Helmet-based system with a Head-tracking device) and compare it with a virtual reality environment using an Immersive Environment (Spherical-based Visualization environment). Two empirical experiments were investigated in this study, each consisting of thirty-five subjects. A virtual airplane scenario was created and simulated for the participants of both environments. Participants were given several questionnaires after completing the simulation. This study mainly focused on question 9 and 10 of that survey, which dealt with how much the participant felt present in the virtual environment, and if the presence of the real world could still be experienced while in the virtual environment. We found that the subjects felt more involved with the virtual environment while using the Immersive Environment simulation versus using the traditional helmet-based Virtual Reality Environment. There was a statistically significant difference in questions 9 and 10 between the Immersive Environment and traditional Virtual Reality Environment when those questions are considered in isolation. However there was not a significant difference in the total sense of presence between the two environments after analyzing the questions together. The primary differences between the questions were analyzed using the overall mean and the standard deviation. The Immersive Environment has a smaller deviation than the traditional Virtual Reality Environment, implying that the sense of presence response is more concentrated. However, the overall results demonstrate that both environments are almost equally effective, with the Immersive Environment having several slight advantages.

Using empirical data, this research suggests that key features of a typical theatrical rehearsal process can significantly improve the sense of presence for participants within a shared virtual environment. Research of shared virtual environments (VEs) for the production of theater shows suggests that theater applications have specific requirements for presence. These can be summarized as characterization, repetition, and group dynamic, while the level of presence is dependent on the actor-avatar, actor-space, and actor-actor relationships.

There are many virtual environments found in the serious game community that simulate real world scenarios. There is a broad range of fidelity and experimental controls among these serious games. An important component to most evaluations is the extent to which level of fidelity impacts the persons immersed in the serious game. While a great deal of virtual environment and serious game research has assessed the subjective state or feeling of the participant (e.g., the participant’s sense of presence) through the use of questionnaires, the current study examines participant experience by examining psychophysiological responses of participants to their surroundings. The primary goal in this study was evaluative: will a virtual environment with arousing contents result in increased sensory arousal if it is presented in a highly immersive configuration? A secondary goal of this study was to investigate the utility of our environment to offer varying levels of stimulus threat to impact the user’s experience of the virtual environment. Increased simulation fidelity in an arousing environment resulted in faster heart rates and increased startle eyeblink amplitudes, suggesting that higher fidelity scenarios had great efficacy related to sensory arousal.
