In this paper, we (i) introduce the Computer-Based Training (CBT) context, in particular CBT that employs Virtual Reality (VR) technologies; (ii) describe the generic environment we developed to allow the employment of immersive hardware in Web3D applications, (iii) describe the immersive Virtual Training (iVT) application we have built for the training of industrial maintenance personnel.

The study focused primary teachers views on the educational use of Virtual Environments (VEs). A 3D reconstruction of a Portuguese Romanesque castle, XII Century, was developed. A sample of 21 teachers explored the VE. The study intended to construct a detailed description of the exploration process implemented by the school teachers and to elicit their perspective on the educational potential ...

The present survey explored the acceptability of virtual reality (VR) exposure and in vivo exposure in 150 participants suffering from specific phobias. Seventy-six percent chose VR over in vivo exposure, and the refusal rate for in vivo exposure (27%) was higher than the refusal rate for VR exposure (3%). Results suggest that VR exposure could help increase the number of people who seek exposu...

Virtual Reality (VR) is amongst the technologies that have existed as early as the 1960s. Only until recently it has resurrected and is making a comeback into many shapes and forms of our daily lives. This paper describes in general the use of VR tools in the manufacturing sector. Examples of successful adoption of VR technologies in manufacturing companies and organisations are described. Issu...

There have been several networked virtual environments (NVEs) described in the literature. Each NVE system considers a separate part of the problem and a reference frame for listing all components and comparing different NVEs missing. We summarize the issues to consider while developing complete NVEs, and we compare the most characteristic solutions in the literature for each issue.

This paper proposes the use of Virtual Reality (VR) as the enabling tool for delivering and learning construction layout and surveying. VR is used to provide an interactive learning experience through real-time computer generated imagery (CGI). The students learn and apply the theoretical part of the class through the interaction with the virtual surveying equipment in a virtual environment (VE...

Performance is one of the most critical aspects of creating an immersive application, affecting the comfort of users and their ability to interact with the environment itself. This paper discusses the importance of including application-extensible, real-time-viewable performance monitoring capabilities in Virtual Reality (VR) development systems. It describes how an extensible performance-monit...

Prevalent area of exploitation of CAM (Computer Aided Manufacturing) systems is computer aided program creating for NC production equipment. However, CAM systems do not sufficiently cover all periods of production process and due to this, the necessity to define the systems of Computer Aided Manufacturing Engineering CAME is obvious. Augmented Reality (AR) mixes virtual world with the actual wo...

The aircraft inspection/maintenance system, which is influenced by based operators and regulated by the FAA, consists of several interrelated human and machine components. In this process, visual inspection plays a significant role in ensuring aircraft safety. To improve the quality and reliability of aircraft inspection, training and job aiding have been identified as the two most important in...

 Virtual Reality (VR) systems allows the design of interactive and immersive environments for the simulation of a wide range of situations. These features has been exploited to build realistic applications in order to provide study and training in several areas, particularly in medicine. In this sense, the addition of techniques to assess the actions of users can provide simulations based on v...
