Augmented Reality (AR) is a visualization technique in which computer generated graphics are superimposed over one's view of the real world. This paper reports results of recent studies in which navigation data was superimposed into a ship pilot's field of view, including a system recently instaIIed on the US military s High Speed Catamaran Joint Venture (HSV-Xl). The system displays both navig...

Anxiety disorders, including phobias and post-traumatic stress disorder, are common and disabling disorders that often involve avoidance behavior. Cognitive-behavioral treatments, specifically imaginal and in vivo forms of exposure therapy, have been accepted and successful forms of treatment for these disorders. Virtual reality exposure therapy, an alternative to more traditional exposure-base...

The efficacy of virtual reality (VR) exposure therapy was examined for the fear of flying. Virtual reality exposure involved six sessions of graded exposure to flying in a virtual airplane. The specific contribution of anxiety management techniques (AMT) and the VR exposure was examined in a single case design. The subject was a 42-year-old female with a debilitating fear and avoidance of flyin...

A number of carefully controlled studies have documented the effectiveness of traditional imaginal exposure for the treatment of post-traumatic stress disorder (PTSD). Virtual reality (VR) exposure therapy is based on a similar logic but rather than self-generating imagery, patients wear a VR helmet and go into a three-dimensional (3-D) computer generated virtual world to help them gain access ...

This paper presents a technology for supporting in-house forensic CG video generation by police and prosecution. For confidentiality, it is usually not allowed to generate criminal CG video through subcontracting, whereas existing CG modeling and video editing systems are too complicated to use for police or prosecution. The proposed technique solves this problem with Augmented Reality (AR) tec...

This paper describes research that investigated the application of 3D Augmented Reality (AR) for animating traffic simulation models in real time to support the planning and design of road construction projects. Traditional 3D visualization applications use Virtual Reality (VR) environments to visualize traffic simulations. The significant amount of time and human resources required to collect ...

Virtual Reality (VR) provides users advanced visualization and interaction technology for designing, analyzing and exploring complex data. To address the issue of noise in manufacturing environments, we developed a VR-supported method allowing users to explore noise behavior. This method consists of an implementation of acoustic simulation and visualization for both desktop and Cave Automatic V...

Digitally based courses and their online delivery are rapidly expanding access to learning opportunities (Duffy and Kirkley 2004; NRC 2000; Visser and Visser-Valfrey 2008). It is important to ask however: access to what kind of learning opportunities? Weigel (2000) argues that most current attempts to create online learning environments suffer from a "port the classroom to the Web" model. Resea...
