The concept of Augmented Reality (AR) displays is defined, in relation to the amount of real (unmodelled) and virtual (modelled) data presented in an image, as those displays in which real images, such as video, are enhanced with computer generated graphics. For the important class of stereoscopic AR displays, several factors may cause potential perceptual ambiguities, however, which manifest t...

Virtual reality exposure therapy is slowly becoming a viable option for therapists. For virtual reality systems to be used in the daily practice of therapists, their usability needs to be taken into consideration. This paper describes the current state-of-the-art in interfaces for these systems, and describes several proposals for improving the design of these systems. An exploratory evaluation...

A specific phobia is a common anxiety-related disorder that can be treated efficiently using different therapies including exposure therapy or cognitive therapy. One of the most famous methods to treat Exposure involves exposing target patient anxiety source its context without intention cause any danger. promising track research lies in VR (VRET) and/or AR (ARET), where gradual negative stimul...

A growing body of literature suggests that virtual reality is a successful tool for exposure therapy in the treatment of anxiety disorders. Virtual reality (VR) researchers posit the construct of presence, defined as the interpretation of an artificial stimulus as if it were real, to be a presumed factor that enables anxiety to be felt during virtual reality exposure therapy (VRE). However, a h...

With more and more workflow systems adopting cloud as their execution environment, it becomes increasingly challenging on how to efficiently manage various workflows, virtual machines (VMs) and workflow execution on VM instances. To make the system scalable and easy-to-extend, we design a Workflow as a Service (WFaaS) architecture with independent services. A core part of the architecture is ho...

Virtual Communities (VCs) offer ubiquitous access to information and exchange possibilities for people in similar circumstances. This is especially valuable for patients with chronic / life-threatening diseases as they exhibit strong needs for information and interaction. Grounded on the preceding findings of the analysis on the user-centric construction of the VC krebsgemeinschaft.de, this art...

In face of the high number of different hardware platforms that we need to program in the Internet-of-Things (IoT), Virtual Machines (VMs) pose as a promising technology to allow a program once, deploy everywhere strategy. Unfortunately, many existing VMs are very heavy to work on resourceconstrained IoT devices. We present COISA, a compact virtual platform that relies on OpenISA, an Instructio...

This paper focuses on the development of a new spatial ability test in virtual reality (VR). This test measures the ability to visualize and mentally manipulate three-dimensional objects directly in 3D space, and should thus have a higher ecological validity than previous spatial ability tests. Items are viewed through head mounted displays and manipulated by means of a wireless pen input devic...

Per capita, Australia has the highest rate of greenhouse gas emissions in the industrialised world (Turton & Hamilton, 2002). As such, it is increasingly recognised that engaging Australians in environmentally sustainable practices and behaviours is central to reducing greenhouse gas emissions for a sustainable future. This paper proposes a conceptual framework for engaging people in environmen...
