A student's perspective: getting real with virtual reality

As with many up and coming technologies, the road to wide acceptance is not always smooth. Virtual reality (VR) is one such technology whose bumpy ascent is well underway. VR is not all that new but the steady price/performance gains for computational power have helped it gain a broader base of applications and even a little popularity along the way. The author's current research is one example of how VR can be used as an analysis as well as a visualization tool. He is developing interactive scenarios where the user can pose "what if?" questions in a VR environment and the VR environment will respond with an array of possibilities. The user will then be able to experience and better assess the impacts of each alternative. The interactive aspects of VR make it an ideal platform for developing scenarios across a broad range of applications.     

Real people in surreal environments

With high performance computer processing capabilities and appropriate communication bandwidths, virtual reality (VR) and enhanced reality systems are no longer restricted to sophisticated flight simulators. Now there is the opportunity for users to immerse themselves in new worlds and to learn, work and play in different ways. This paper presents some of the key research issues that need to be addressed in order to develop virtual environments (VEs) which will ‘succeed’ across a range of VR application areas, including: What are the key components that constitute compelling, stimulating and easy-to-use VEs? What constitutes a usable VE? Do we understand the human element of VR? Techniques and approaches that will increase our understanding of VR from the user perspective are presented, together with ‘The Mirror’ case study which demonstrates the assessment methodology used to address performance and usability issues relating to a collaborative environment delivered over the Internet.     

Virus tinged? Exploring the facets of virtual reality use in tourism as a result of the COVID-19 pandemic

Several studies have investigated the use of virtual reality (VR) in tourism, but none has taken an epidemiological outlook. This research examined the use of VR in tourism through the lenses of an extended TAM model in times of COVID-19 pandemic. The premise was that, in this context, people would prefer less risky experiences and would see VR as a substitute for traditional travel. The data used was collected through a within-subjects experiment, which proved that intention to use VR in tourism increased under the COVID-19 effect. This study tested a conceptual model that showed this intention was influenced by the perceived ease of use, perceived usefulness, and perceived substitutability of VR, all mediated by people’s interest in VR use in tourism. The perceived authenticity of VR experience determined the perceived substitutability of VR. This paper has theoretical and practical implications. In the long term, promoting tourism-related VR activities might reduce the risk of virus spreading, lessen the pressure imposed on this sector by such epidemic episodes, and increase its sustainability.     

Virtual surgery in a (tele-)radiology framework

Presents telemedicine as an extension of a teleradiology framework through tools for virtual surgery. To classify the described methods and applications, the research field of virtual reality (VR) is broadly reviewed. Differences with respect to technical equipment, methodological requirements and areas of application are pointed out. VR, desktop VR and augmented reality are differentiated and discussed in some typical contexts of diagnostic support, surgical planning, therapeutic procedures, simulation and training. Visualization techniques are compared as a prerequisite for VR and assigned to distinct levels of immersion. The advantage of a hybrid visualization kernel is emphasized with respect to the desktop VR applications that are subsequently shown. Moreover, software design aspects are considered by outlining functional openness in the architecture of the host system. A teleradiology workstation was extended by dedicated tools for surgical planning through a plug-in mechanism. Examples of recent areas of application are introduced, such as liver tumor resection planning, diagnostic support in heart surgery, and craniofacial surgery planning. In the future, surgical planning systems will become more important. They will benefit from improvements in image acquisition and communication, new image processing approaches and techniques for data presentation. This will facilitate pre-operative planning and intra-operative applications

Close encounters of the virtual kind

The brain activity of humans and many other animals is dominated by processing visual images relative to body position. This is not to sell short other sensory paths such as heaving or smell, which are also exquisitely sensitive. The complexity of visual interpretation requires a very interactive and highly parallel brain function. It is not surprising that VR, which depends on interactivity between sensing and the kinetic domains of the body, has emphasized visual applications. Virtual reality is now being used to enhance other senses like touch and hearing. The key contribution of VR is the ability to interact with the human brain at a higher and more creative level than you might experience by looking at a monitor screen, or reading print from the page as you are doing now. At the present time most VR demonstrations have the appearance of being a solution in search of a problem. Applications that truly exploit the power of this technology will surely continue to develop as more people experience the effect of VR and learn how to harness and then to leverage the power in this mode of communication     

Research on virtual reality system design for body and psychological rehabilitation

There are many people in China who suffered from physical and mental diseases and need physical and psychological rehabilitation. Traditional treatments can work in rehabilitation, but will take much money and labor. In recent years, virtual reality (VR) technology has become a new direction to innovate rehabilitation. This paper summarizes the research results of VR technology in rehabilitation for stroke, anxiety, depression and autism. Based on these results, we propose a framework for VR rehabilitation system with virtual agents. A prototype system is developed to corroborate the proposed design guidelines. With the prototype rehabilitation system, autistic children can train their life skills in different scenarios. Preliminary test results show the proposed framework can push users to take the rehabilitation training actively and can be a new method for rehabilitation training.

Virtual Environments for Anyone

Editors' NoteDifferent demands to computing power, graphics processing capabilities, and modalities of user interaction have traditionally kept VR, computer graphics, and games separate research domains. But recently, powerful programmable GPUs and VR-style input devices like the Wii controller have become common. Expensive, custom-built hardware setups are no longer needed to build exciting VR appliances.In this issue's column, Heinrich Godbersen from TFH Berlin argues that this change will bring the worlds of VR, computer graphics, and games together. He discusses how technological advances enable him to move between those worlds and create game-like VR appliances such as Flight Vienna with inexpensive commodity hardware and development tools.—William I.
