Olfaction is the most ancient sense and is directly connected with emotional areas in the brain. It gives rise to perception linked to emotion both in everyday life and in memory-recall activities. Despite its emotional primacy in perception and its role in sampling the real physical world, olfaction is rarely used in clinical psychological settings because it relies on stimuli that are difficult to deliver. However, recent developments in virtual-reality tools are creating novel possibilities for the engagement of the sense of smell in this field. In this article, we present the relevant features of olfaction for relaxation purposes and then discuss possible future applications of involving olfaction in virtual-reality interventions for relaxation. We also discuss clinical applications, the potential of new tools, and current obstacles and limitations.

Currently, virtual reality (VR) is a computer technology that is growing in terms of developments and discoveries. Virtual reality has been introduced in different areas due to the growing interest it has caused in people. The development of applications with virtual reality is increasingly varied, covering activities, tasks, or processes of everyday life in the fields of industry, education, medicine, tourism, art, entertainment, design, and modeling of objects, among others. This chapter will focus on describing the latest advances and developments in virtual reality within the scope of representing reality in the process of locating objects. With the support of virtual environments and intelligent virtual agents, the author has managed to develop a computational model that generates indications in natural language, for the location of objects considering spatial and cognitive aspects of the users.

Imaging of the structure and function of the human brain has grown to an area with increasing impact on neuropsychological research as well as on the routine clinical evaluation of brain damaged patients. The scientific and popular literature is now flooded by increasingly more spectacular pictures of the brain. The images no longer only illustrate what is well known from earlier research but they do also sometimes provide information of importance for the further development of neuropsychological theories. The two volumes edited by Erin D. Bigler, Neuroimaging I and II, offer a possibility for neuropsychologists and other interested readers to get acquainted with the more recent developments in measurement technology and applications in basic science (Volume I) as well as in the clinic (Volume II). The authors of the 24 chapters are generally outstanding researchers, with impressive expertise within their fields of specialization.

Predicting Behavior

Discrepanices between perceived and actual distance may affect people's spatial behavior. In a previous study Nasar, using self report of behavior, found that segmentation (measured through the number of buildings) along the route affected choice of parking garage and path from the parking garage to a destination. We recreated that same environment in a three-dimensional virtual environment and conducted a test to see whether the same factors emerged under these more controlled conditions and to see whether spatial behavior in the virtual environment accurately reflected behavior in the real environment. The results confirmed similar patterns of response in the virtual and real environments. This supports the use of virtual reality as a tool for predicting behavior in the real world and confirms increases in segmentation as related to increases in perceived distance.

The ability to view constructions virtually before using the real resources to construct them has been of main interest in civil engineering over a long period of time. This has been achieved partially through virtual reality. Virtual Reality helps in visualizing the operations on computer generated jobsites and to study the available alternate plans. Even though the latest software in virtual reality helps us in designing and drawing the plans, the question of reality still arises. The plans that are done in computer sometimes do not match with the real practical applications. This shows that it is difficult to bring the experiences of practical world into the computer. In order to overcome the gap between the real and virtual environments, this paper highlights the use of Augmented Reality (AR) in all the areas of civil engineering instead of using Virtual Reality. This paper describes the developing augmented reality technology and its various application domains in civil engineering.

It is often questioned whether task performance attained in a virtual environment can be transferred appropriately and accurately to the same task in the real world. With advancements in virtual reality (VR) technology, recent research has focused on individuals’ abilities to transfer calibration achieved in a virtual environment to a real-world environment. Little research, however, has shown whether transfer of calibration from a virtual environment to the real world is similar to transfer of calibration from a virtual environment to another virtual environment. As such, the present study investigated differences in calibration transfer to real-world and virtual environments. In either a real-world or virtual environment, participants completed blind walking estimates before and after experiencing perturbed virtual optic flow via a head-mounted virtual display (HMD). Results showed that individuals calibrated to perturbed virtual optic flow and that this calibration carried over to both real-world and virtual environments in a like manner.

The term ‘virtual reality' is used widely in contemporary culture to evoke the false worlds of the imagination digital technology has enabled us to create. However, the term itself remains ill defined, particularly amidst recent developments in theories of virtuality and reality that have left contradictory marks on VR. The phrase ‘virtual reality' has become problematic, and is in need of a reconsideration for its continued relevance. This chapter assesses the term throughout its development and in the context of other theorisations such as cinema and cyberspace that have dominated recent digital theory. Taking the Deleuzian expansion of the Virtual and the Lacanian expansion of the Real, the chapter interrogates the constituent processes of VR to suggest a new mode of conceiving the technologies in terms of a parallax between virtual-real and physical-digital within contemporary thought, which will then be applied to a conceptual framework for digital creative practices.

Boundary element (BE) analysis is well known as a tool for assessing the stiffness and strength of engineering components, but, along with finite element (FE) techniques, it is also finding new applications as a means of simulating the behaviour of deformable objects within virtual reality simulations since it exploits precisely the same kind of surface-only definition used for visual rendering of three-dimensional solid objects. This paper briefly reviews existing applications of BE and FE within virtual reality, and describes recent work on the BE-based simulation of aspects of surgical operations on the brain, making use of commercial hand-held force-feedback interfaces (haptic devices) to measure the positions of the virtual surgical tools and provide tactile feedback to the user. The paper presents an overview of the project then concentrates on recent developments, including the incorporation of simulated tumours in the virtual brain.

Virtual reality systems are a popular tool in behavioral sciences. The participants’ behavior is, however, a response to cognitively processed stimuli. Consequently, researchers must ensure that virtually perceived stimuli resemble those present in the real world to ensure the ecological validity of collected findings. Our article provides a literature review relating to distance perception in virtual reality. Furthermore, we present a new study that compares verbal distance estimates within real and virtual environments. The virtual space—a replica of a real outdoor area—was displayed using a state-of-the-art head-mounted display. Investigated distances ranged from 8 to 13 m. Overall, the results show no significant difference between egocentric distance estimates in real and virtual environments. However, a more in-depth analysis suggests that the order in which participants were exposed to the two environments may affect the outcome. Furthermore, the study suggests that a rising experience of immersion leads to an alignment of the estimated virtual distances with the real ones. The results also show that the discrepancy between estimates of real and virtual distances increases with the incongruity between virtual and actual eye heights, demonstrating the importance of an accurately set virtual eye height.

AbstractIn “The Virtual and the Real,” David Chalmers argues that there is an epistemic and ontological parity between VR and ordinary reality. My argument here is that, whatever the plausibility of these claims, they provide no basis for supposing that there is a similar parity of value. Careful reflection upon certain aspects of the transition that individuals make from interacting with real-world, physical environments to interacting with VR provides a basis for thinking that, to the extent that there are good reasons to deny the reality of virtual objects, there are also reasons to place a correspondingly higher value upon the experience of interacting with a VR environment. Chalmers’ assumption to the contrary arises from a subtle misrepresentation of how the phenomenon of cognitive penetration works in the perception of virtual objects, and from an unwillingness to acknowledge how our attitudes toward virtual environments are conditioned by the values we adopt when engaged in gameplay.
