A virtual environment is a computer-generated world accessible to a (human) user through input/output devices. It is similar to a traditional simulation but with an emphasis on threedimensional graphics, immersion and real-time interaction. A distributed virtual environment has several participants interacting simultaneously with the virtual world. An example application would be a surgical tra...

Single display privacyware is a technique for collaborative interaction in which one display is used for multiple users, but each user is able to see certain private information that others cannot. In this paper, we describe and evaluate two applications of single display privacyware. One is the use of fish tank virtual reality for multiple users, and the other is hiding private information fro...

An ethnographic analysis of an ambulance control centre is presented, specifically investigating the design of information displays and their practical use in this setting. The spatial distribution of the displays around the control room is described and its consequences for cooperative work drawn out. From these analyses, we make several suggestions for information visualisations in virtual en...

abstract: enviromental concerns, improvements in renewable energy technologies, governmental incentives for the use of these resources, and increased t&d; costs, are the main factors driving the energy sector into a new era, where considerable portions of electrical demand will be met through widespread installation of distributed energy resources (ders). the virtual power plant (vpp) is a dece...

Virtual reality (VR) exposure therapy is a common treatment for phobia and the efficacy of this technique has proved. The darkness phobia is one of the most common disorders among the children. This is the first research about the darkness phobia and using VR to treat the patients. The VR system designed in this article is composed from two parts: Mechatronic devices and graphics unit. As a chi...

This work presents a system for providing ubiquitous visual information to actors in a virtual studio, blue screen, or other mixed reality environment. The Scanning Mirror Projector (ScaMP) system uses steerable projection and head pose estimation to form a new type of ever-present display that projects visual information of a virtual world to the gaze direction of the user. This system allows ...

We discuss on the potential of suspensions of gold nanoparticles with variable refractive index for the possible physical realization of in-relief virtual dynamic display of plane images. A reasoning approach for a vision system to display in real-time volumetric moving images is proposed based on well-known properties of optical media, namely the anomalous dispersion of light on certain transp...

Water is the first and foremost limiting factor for agricultural production, and undoubtedly, water crisis is considered as one of the international challenges for governments and human societies. Given that virtual water was first used as a way to tackle water scarcity in countries with limited water resources, so that countries with low water should import food from abundant countries...
