Virtual reality (VR) is the term used to describe representation and perception in a computer-generated, virtual environment. The term was coined by author Damien Broderick in his 1982 novel “The Judas Mandala". The term "Mixed Reality" describes the mixing of virtual reality with pure reality. The term "hyper-reality" is also used. Immersion plays a major role here. Immersion describes the embedding of the user in the virtual world. A virtual world is considered plausible if the interaction is logical in itself. This interactivity creates the illusion that what seems to be happening is actually happening. A common problem with VR is "motion sickness." To create a sense of immersion, special output devices are needed to display virtual worlds. Here, "head-mounted displays", CAVE and shutter glasses are mainly used. Input devices are needed for interaction: 3D mouse, data glove, flystick as well as the omnidirectional treadmill, with which walking in virtual space is controlled by real walking movements, play a role here.

Human Factors Research

Recent advances in technology have made virtual environments, virtual reality, augmented reality, and simulations more affordable and accessible to researchers, companies, and the general public, which has led to many novel use cases and applications. A key objective of human factors research and practice is determining how these technology-rich applications can be designed and applied to improve human performance across a variety of contexts. This session will demonstrate some of the distinct and diverse uses of virtual environments and mixed reality environments in an alternative format. The session will begin with each demonstrator providing a brief overview of their virtual environment (VE) and a description of how it has been used to address a particular problem or research need. Following the description portion of the session, each VE will be set-up at a demonstration station in the room, and session attendees will be encouraged to directly interact with the virtual environment and ask demonstrators questions about their research and inquire about the effectiveness of using VE for research, training, and evaluation purposes. The overall objective of this alternative session is to increase the awareness of how human factors professionals use VE technologies and increase the awareness of the capabilities and limitations of VE in supporting the work of HF professionals.

Abstract The purpose of this article is to highlight the state of the art of virtual reality, augmented reality, mixed reality technologies and their applications in formal education. We also present a selected list of case studies that prove the utility of these technologies in the context of formal education. Furthermore, as byproduct, the mentioned case studies show also that, although the industry is able to develop very advanced virtual environment technologies, their pedagogical implications are strongly related to a well-designed theoretical framework.

The analysis of the ship layout from the point of view of safe and orderly evacuation represents an important step in ship design, which can be carried out through agent-based evacuation simulation tools, typically run in batch mode. Introducing the possibility for humans to interactively participate in a simulated evacuation process together with computer-controlled agents can open a series of interesting possibilities for design, research and development. To this aim, this article presents the development of a validated agent-based evacuation simulation tool which allows real-time human participation through immersive virtual reality. The main characteristics of the underlying social-force-based modelling technique are described. The tool is verified and validated by making reference to International Maritime Organization test cases, experimental data and FDS + Evac simulations. The first approach for supporting real-time human participation is then presented. An initial experiment embedding immersive virtual reality human participation is described, together with outcomes regarding comparisons between human-controlled avatars and computer-controlled agents. Results from this initial testing are encouraging in pursuing the use of virtual reality as a tool to obtain information on human behaviour during evacuation.

Clear Objective

The objective of this study was to use virtual reality as a validation method of a new multimodal warning for use in situations of risk and danger. This warning is intended to be more efficient than the static warnings as regards their ability to convey clear, objective information and securely. The virtual environment used was developed with immersive virtual reality simulating a risk and danger to the user. This virtual environment allows situations are simulated in real life would be impossible for putting at risk the lives of people. For the warning efficiency were evaluated, we used two warnings, static and multimodal, which consisted of harmonization between the ISO and ANSI standards. As innovation factor used was the explanation of the consequences of non-compliance. Multimodal elements used in the notice were a file with a recorded human voice and a flashing red light. These results demonstrated that the virtual environment used, and the multimodal warning were efficient in their goals. The results of the variables used were positive and the hypotheses was validated with the use of statistical tests.

In this study, we propose the use of mixed reality (MR) for the purposes of biological education. Our objective is to create an interactive edutainment MR framework for users to learn about nature and human beings. MitsuDomoe, an interactive ecosystem simulator of virtual creatures in a petri dish, comprises three species of primitive artificial creatures. MitsuDomoe simulates the predation chain of the virtual creatures in the petri dish, and users can interact with this ecosystem via the petri dish interface. Users can also experience immersive observation by wearing HMD. By combining the MR petri dish and immersive virtual reality (VR) interfaces, we synergistically improve user understanding of the experience.

<p><strong>Abstract.</strong> In this paper, we analysed and tested the possibilities for the use of low-cost VR (Virtual Reality) headsets, with a focus on cartographic visualization. Low-cost devices were compared and classified into three categories (low-end, mid-range and high-end). We also created a pilot virtual environment, called “Carthoreality”, and conducted simple pilot user testing using this virtual environment and the three low-end headsets. Our pilot test shows a few drawbacks to these devices, including weight of the headset and penetrating light. Some problems in terms of user aspects were also identified, such as nausea while wearing headsets or disorientation after removing them, which occurred for all users.</p>

Methods Of Evaluation

The Meditation Chamber is an immersive virtual environment (VE), initially created to enhance and augment the existing methods of training users how to meditate, and by extension, to realize the benefits from meditation practice, including the reduction of stress, anxiety and pain. Its innovative combination of immersive virtual reality (VR) and biofeedback technologies added interoceptive or dimensions of inner senses to the already sensorially rich affordances of VR. Because the Meditation Chamber enabled users to become aware of autonomic senses that they are not normally conscious of, and to manipulate them in real-time, we found that it did enhance users’ abilities to learn how to meditate, particularly those who had never meditated. We describe the Meditation Chamber, scientific methods of evaluation and findings, and discuss first-person phenomenological aspects, its long-term applicability for users who have chronic pain, and future directions.

AbstractThe birth of virtual reality marked a new path forward and also gave a fresh view of reality, allowing alternative ‘readings’ of cultural heritage. This new way of representation and simulation was soon associated with the term virtual environment, used to indicate those interactive three-dimensional models that could be navigated and that simulated a place, building, or synthetic representation scheme in real time. A virtual environment is like a “microscope for the mind” that allows you to elaborate amplified projections of the material world, to “look beyond” simple appearances and to make logical connections between elements grouped together. In recent years, virtual environments have been greeted positively by the public and scholars, testified by the quantity of thematic conferences on the subject of Virtual Archaeology. Despite this, there are still many contradictions found in the varying terms and the diverse aims of the developing disciplines that gravitate around the field of virtual reality such as Cultural Virtual Environment, Virtual Restoration, Virtual Archaeology, Enhanced Reality, and Mixed Reality. The spread of new media has upset the traditional systems of communication such as books, television, radio and even the roles of some cultural stakeholder. With this in mind, the role of virtual heritage also consists in transmitting information using the language and cognitive metaphors used in video-games, considering these as cultural paradigms for a form of communication that is freed from the classic rules of elite culture. It is quite frequent to find projects of digital promotion for monuments that are characterised by difficulty of access, or for objects that have been taken from their original context. One solution to enhance the accessibility of those sites is certainly the use of some visual computing technologies which without presuming to be the ultimate answer to the problems posed, try to offer communications tools that permit an effective support to the visit.
