The popular concepts of Virtual Reality (VR) and Augmented Reality (AR) arose from our ability to interact with objects and environments that appear to be real, but are not. One of the most powerful aspects of these paradigms is the ability of virtual entities to embody a richness of behavior and appearance that we perceive as compatible with reality, and yet unconstrained by reality. The freedom to be or do almost anything helps to reinforce the notion that such virtual entities are inherently distinct from the real world—as if they were magical. This independent magical status is reinforced by themore »
Exploring Virtual Environments by Visually Impaired Using a Mixed Reality Cane Without Visual Feedback
Though virtual reality (VR) has been advanced to certain levels of maturity in recent years, the general public, especially the population of the blind and visually impaired (BVI), still cannot enjoy the benefit provided by VR. Current VR accessibility applications have been developed either on expensive head-mounted displays or with extra accessories and mechanisms, which are either not accessible or inconvenient for BVI individuals. In this paper, we present a mobile VR app that enables BVI users to access a virtual environment on an iPhone in order to build their skills of perception and recognition of the virtual environment and the virtual objects in the environment. The app uses the iPhone on a selfie stick to simulate a long cane in VR, and applies Augmented Reality (AR) techniques to track the iPhone’s real-time poses in an empty space of the real world, which is then synchronized to the long cane in the VR environment. Due to the use of mixed reality (the integration of VR & AR), we call it the Mixed Reality cane (MR Cane), which provides BVI users auditory and vibrotactile feedback whenever the virtual cane comes in contact with objects in VR. Thus, the MR Cane allows more »

Dini, Petre (Ed.)The National Academy of Engineering’s “Fourteen Grand Challenges for Engineering in the Twenty-First Century” identifies challenges in science and technology that are both feasible and sustainable to help people and the planet prosper. Four of these challenges are: advance personalized learning, enhance virtual reality, make solar energy affordable and provide access to clean water. In this work, the authors discuss developing of applications using immersive technologies, such as Virtual Reality (VR) and Augmented Reality (AR) and their significance in addressing four of the challenges. The Drinking Water AR mobile application helps users easily locate drinking water sources inside Auburn Universitymore »

Spatial reasoning skills contribute to performance in many STEM fields. For example, drawing sectional views of three-dimensional objects is an essential skill for engineering students. There is considerable variation in the spatial reasoning skills of prospective engineering students, putting some at risk for compromised performance in their classes. This study takes place in a first-year engineering Spatial Visualization course to integrate recent practices in engineering design education with cognitive psychology research on the nature of spatial learning. We employed three main pedagogical strategies in the course - 1) in class instruction on sketching; 2) spatial visualization training; and 3) manipulationmore »

The goal of this study was to evaluate driver risk behavior in response to changes in their risk perception inputs, specifically focusing on the effect of augmented visual representation technologies. This experiment was conducted for the purely real-driving scenario, establishing a baseline by which future, augmented visual representation scenarios can be compared. Virtual Reality (VR), Augmented Reality (AR) and Mixed Reality (MR) simulation technologies have rapidly improved over the last three decades to where, today, they are widely used and more heavily relied upon than before, particularly in the areas of training, research, and design. The resulting utilization of thesemore »

Virtual reality (VR) systems have been increasingly used in recent years in various domains, such as education and training. Presence, which can be described as ‘the sense of being there’ is one of the most important user experience aspects in VR. There are several components, which may affect the level of presence, such as interaction, visual fidelity, and auditory cues. In recent years, a significant effort has been put into increasing the sense of presence in VR. This study focuses on improving user experience in VR by increasing presence through increased interaction fidelity and enhanced illusions. Interaction in real lifemore »
