Opportunities for VR in R&D initiatives

Proceedings Virtual Reality Annual International Symposium '95, 1995

Foreword "Timothy Leary Wasn't Invited" It seemed to me that "we" and "they" had both shown up for the first VRAIS conference, VRAIS '93, in Seattle. "We" were the "techies," the scientists and engineers who are exploring and developing virtual environments technology. 'They" were the off-the-wall fringe element that VR seems to attract. "Our" manifesto is that VR is an important new human-computer interface technology with broad potential for educating and training people; helping designers design, even helping to protect people's lives. It is a fascinating area of scientific investigation, one that is inherently multidisciplinary.

During the last decade, Virtual Reality (VR) systems have progressed from primary laboratory experiments into serious and valuable tools. Thereby, the amount of useful applications has grown in a large scale, covering conventional use, e.g., in science, design, medicine and engineering, as well as more visionary applications such as creating virtual spaces that aim to act real. However, the high capabilities of today's virtual reality systems are mostly limited to firstclass visual rendering, which directly disqualifies them for immersive applications. For general application, though, VR-systems should feature more than one modality in order to boost its range of applications. The CAVE-like immersive environment that is run at RWTH Aachen University comprises state-of-the-art visualization and auralization with almost no constraints on user interaction. In this article a summary of the concept, the features and the performance of our VR-system is given. The system features a 3D sketching interface that allows controlling the application in a very natural way by simple gestures. The sound rendering engine relies on present-day knowledge of Virtual Acoustics and enables a physically accurate simulation of sound propagation in complex environments, including important wave effects such as sound scattering, airborne sound insulation between rooms and sound diffraction. In spite of this realistic sound field rendering, not only spatially distributed and freely movable sound sources and receivers are supported, but also modifications and manipulations of the environment itself. The auralization concept is founded on pure FIR filtering which is realized by highly parallelized non-uniformly partitioned convolutions. A dynamic crosstalk cancellation system performs the sound reproduction that delivers binaural signals to the user without the need of headphones. The significant computational complexity is handled by distributed computation on PCclusters that drive the simulation in real-time even for huge audio-visual scenarios.

—Virtual Reality (VR) technology has been used widely today in Science, Technology, Engineering and Mathematics (STEM) fields. The VR is emerging computer interface distinguished by high degrees of immersion, trustworthy, and interaction. The goal of VR is making the user believe, as much as possible, that he is within the computer-generated environment. The VR has become one of the important technologies to be discussed regarding its applications, usage, and its different types that can achieve huge benefits in the real world. This survey paper introduces detail information about VR systems and requirements to build correct VR environment. Moreover, this work presents a comparison between system types of VR. Then, it presents the tools and software used for building VR environments. After that, we epitomize a road of the map for selecting appropriate VR system according to the field of applications. Finally, we introduce the conclusion and future predictions to develop the VR systems.

The construction of a Virtual Reality and Visualization Center in a public or private University results in a series of benefits; it allows the students to interact with modern technology, to learn with different tools. Specifically, this paper focuses on a Virtual Reality and Visualization Center built at the Bachelor in Computer Engineering at the Autonomous University of Tlaxcala, this center is called VirtUATx. VirtUATx allows building different virtual environment multi-screen considering the head movements through a professional head tracker, a full navigation system by means of recognition of body movement's using Kinect or manual using keyboard. Furthermore, VirtUATx incorporates 3D object manipulation, anaglyphic and active stereoscopy and 3D sound. This Center is used in different courses, such as Research Seminars, Computer Graphics, Research Methodology, and Interaction Human-Computer, but in the future this center will benefit other bachelors.

The fourth industrial revolution is characterized by the convergence of various technologies including the Internet of Things, Artificial intelligence, virtual reality, and augmented reality among others. This revolution is shaping how people live, interact, and share information. Virtual Reality (VR) is one of these technologies that are revolutionizing the world. VR technology enables individuals to immerse themselves in a virtual world using special headsets, gloves and computers and has seen its application in several sectors hence improving productivity and do things that could have proven difficult or impossible. This paper explores the evolution of VR technology, its current state, and its application in real life. Through its application, the paper reviews how it has already been applied in industries like entertainment, medicine, education, automotive and others to change how things are done. By using VR, organizations can increase their productivity and give customers a better user experience, increasing sales and profits. Health and safety issues, ethical considerations and costs are also reviewed in this paper. There is a need for collaboration between content creators, developers, policymakers, and researchers to come together and utilize the full potential of this technology while addressing the current challenges.

Virtual Reality (VR) is not a niche but key of a larger trend in next generation Reality Based Interfaces (RBI) according to Robert J. K. Jacob from Tufts University in his keynote address at this year's 3D User Interfaces (3DUI) Symposium, which took place in conjunction with the IEEE Conference on Virtual Reality. "Use reality wherever you can, for the rest, use something different." Jacob (figure 1) encouraged researchers to continue and broaden their work towards the development of interfaces which in his opinion should be based on natural users' skills and incorporate new technologies whenever what we gain by the computers' capabilities is more than we lose by giving up familiarity in handling objects and information.

This paper presents a summary of all on-going projects within the VR-DIS research programme at Eindhoven University of Technology.

Since 1991 Virtual Reality has been used in student projects in the Building Information Technology group. It started as an experimental tool to assess the impact of VR technology in design, using the environment of the associated Calibre Institute. The technology was further developed in Calibre to become an important presentation tool for assessing design variants and final design solutions. However, it was only sporadically used in student projects. A major shift occurred in 1997 with a number of student projects in which various computer technologies including VR were used in the whole of the design process. In 1998, the new Design Systems group started a design studio with the explicit aim to integrate VR in the whole design process. The teaching effort was combined with the research program that investigates VR as a design support environment. This has lead to increasing number of innovative student projects. The paper describes the context and history of VR in Eindhoven and presents the current set-up of the studio. It discusses the impact of the technology on the design process and outlines pedagogical issues in the studio work.
