Human Factors Research

Virtual reality, augmented reality, and other forms of virtual environments have the potential to dramatically change how individuals work, learn, and interact with each other. A key objective of human factors research and practice is to determine how these environments should be designed to maximize performance efficiency, ensure health and safety, and circumvent potential human virtual environment interaction problems. This session will demonstrate some of the distinct and diverse uses of virtual reality, mixed reality, and virtual environments in an alternative format. The session will begin with each demonstrator providing a brief overview of their virtual environment and describing how it has been used to address a particular problem or research need. Following the description portion of the session, all demonstrations will be set-up around the room, and session attendees will be encouraged to directly interact with the environment and ask demonstrators questions about their research and inquire about the effectiveness of using their virtual environment for research, training, and evaluation purposes. The overall objective of this alternative session is to provoke ideas among the attendees for how virtual reality, mixed reality, and virtual environments can help address their research, training, education or business needs.

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.

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.

Person Experience

Virtual reality (VR) technology has the potential to make a person experience anything, anytime, anywhere. It has the ability to influence the human brain that it assumes to be present somewhere that it is really not. In this paper, we exploit this application of the VR technology to simulate virtual environments that can help with PTSD therapy for people affected by trauma due to accident, war, sexual abuse and so on. Several sensors are used to gather the user movements on a motion platform and replicate it in the virtual environment with the help of a Raspberry Pi board and Unreal Developer’s kit. It has flexible interfaces that the clinician can modify the virtual environment according to the requirement for the patient.

Mental Exercise

This paper conducts an extensive survey on existing Virtual Reality (VR)-based rehabilitation approaches in the context of different types of impairments: mobility, cognitive, and visual. Some VR-based assistive technologies involve repetitions of body movements, some require persistent mental exercise, while some work as sensory substitution systems. A multi-modal VR-based environment can incorporate a number of senses, (i.e., visual, auditory, or haptic) into the system and can be an immense source of motivation and engagement in comparison with traditional rehabilitation therapy. This survey categorizes virtual environments on the basis of different available modalities. Each category is again subcategorized by the types of impairments while introducing available devices and interfaces. Before concluding the survey, the paper also briefly focuses on some issues with existing VR-based approaches that need to be optimized to exploit the utmost benefit of virtual environment-based rehabilitation systems .

Virtual City

In recent years virtual environments (VEs) have become more and more popular and widespread due to the requirements of numerous application areas in particular in the 3D city visualization domain. Virtual reality (VR) systems, which make use of tracking technologies and stereoscopic projections of three-dimensional synthetic worlds, support better exploration of complex datasets. However, due to the limited interaction space usually provided by the range of the tracking sensors, users can explore only a portion of the virtual environment (VE). Redirected walking allows users to walk through large-scale immersive virtual environments (IVEs) such as virtual city models, while physically remaining in a reasonably small workspace by intentionally injecting scene motion into the IVE. With redirected walking users are guided on physical paths that may differ from the paths they perceive in the virtual world. The authors have conducted experiments in order to quantify how much humans can unknowingly be redirected. In this chapter they present the results of this study and the implications for virtual locomotion user interfaces that allow users to view arbitrary real world locations, before the users actually travel there in a natural environment.

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.

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 Subject

Like most new technologies, virtual reality (VR) has been the subject of a great deal of idealization. This paper both debunks that idealization by discussing some problems that certain types of VR could cause and emphasizes how other types of VR could bring the technology closer to its ideal. Virtual reality is divided into four types: social (there are real other people to interact with), nonsocial (other interactants are simulations of people), creative (users can create elements in the virtual environment), and noncreative (users interact with a fixed environment created for them). Nonsocial VR may cause problems by making it difficult for children and adolescents to learn social skills. Noncreative VR is problematic because it places limits on users' creativity and freedom. Engineers developing VR technology are encouraged to develop social and creative VR.

Restrict Movement

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.
