A 3D collaborative virtual environment to integrate immersive virtual reality into factory planning processes

As collaborative virtual environments (CVEs) are more widely used, participant access to CVE objects and information becomes a significant concern. In virtual reality games, storefronts, classrooms, and laboratories, for example, the need to control access to spaces and objects is integral to the security of activities taking place there. However, limited access controls are typically available in CVEs. Often, such controls are course-grained, only protecting against movements by unauthorized participants into specific areas. In answer to this deficiency, we offer a discretionary access control (DAC) system based on traditional concepts of users and groups, and tailored to the needs of a CVE. Our system, called WonderDAC, includes the ability to restrict movement into areas, as well as control interactions with objects. A basic WonderDAC prototype has been implemented within the Project Wonderland CVE.

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.

Virtual Reality Application

<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.

What viable technologies exist to enable the development of so-called desktop virtual reality (desktop-VR) applications? Specifically, which of these are active and capable of helping us to engineer a collaborative, virtual environment (CVE)? A review of the literature and numerous project websites indicates an array of both overlapping and disparate approaches to this problem. In this paper, we review and perform a risk assessment of 16 prominent desktop-VR technologies (some building-blocks, some entire platforms) in an effort to determine the most efficacious tool or tools for constructing a CVE

In this paper we present a virtual tennis game. We describe the creation and modeling of the virtual humans and body deformations, also showing the real-time animation and rendering aspects of the avatars. We focus on the animation of the virtual tennis ball and the behavior of a synthetic, autonomous referee who judges the tennis games. The networked, collaborative, virtual environment system is described with special reference to its interfaces to driver programs. We also mention the virtual reality (VR) devices that are used to merge the interactive players into the virtual tennis environment, together with the equipment and technologies employed for this exciting experience. We conclude with remarks on personal experiences during the game and on future research topics to improve parts of the presented system.

PurposeThe purpose of this paper is to examine how the use of immersive virtual reality (IVR) impacts on the surprise aspects of designing.Design/methodology/approachThe empirical case is a new hospital in the UK wherein a CAVE (Cave Automatic Virtual Environment) type of an IVR environment was used performing six design review sessions during the bid preparation stage. Drawing from a former video-based study, the authors conducted follow-up discussions with the participants to access their perspectives on design surprises emerging from their engagement with the IVR. The study developed a reflective methodology, interviewing participants about their experiences of doing design in the immersive environment. Retrospective discussions were conducted in a data review format, through playing back video clips of the IVR design sessions and asking the participants to reflect on their IVR design experience and on design surprises emerging from their engagement with the IVR.FindingsThe findings indicate that IVRs, such as the CAVE, are not only enhancing existing understandings of design but also challenging the participants' understanding of the design as they experience the immersive version of it, provoking ruptures in current procedures and driving unanticipated changes to the design.Originality/valueThis qualitative study of surprise in design work using IVRs (for a real-life design project) brings new insights into emerging practices of designing using immersive technology, such as the CAVE.

The Impact

Immersive virtual reality (iVR) devices are rapidly becoming an important part of our lives and forming a new way for people to interact with computers and each other. The impact and consequences of this innovative technology have not yet been satisfactory explored. This empirical study investigated the cognitive and social aspects of collaboration in a shared, immersive virtual reality. A unique application for implementing a collaborative immersive virtual environment (CIVE) was developed by our interdisciplinary team as a software solution for educational purposes, with two scenarios for learning about hypsography, i.e., explanations of contour line principles. Both scenarios allow switching between a usual 2D contour map and a 3D model of the corresponding terrain to increase the intelligibility and clarity of the educational content. Gamification principles were also applied to both scenarios to augment user engagement during the completion of tasks. A qualitative research approach was adopted to obtain a deep insight into the lived experience of users in a CIVE. It was thus possible to form a deep understanding of very new subject matter. Twelve pairs of participants were observed during their CIVE experience and then interviewed either in a semistructured interview or a focus group. Data from these three research techniques were analyzed using interpretative phenomenological analysis, which is research method for studying individual experience. Four superordinate themes—with detailed descriptions of experiences shared by numerous participants—emerged as results from the analysis; we called these (1) Appreciation for having a collaborator, (2) The Surprising “Fun with Maps”, (3) Communication as a challenge, and (4) Cognition in two realities. The findings of the study indicate the importance of the social dimension during education in a virtual environment and the effectiveness of dynamic and interactive 3D visualization.
