Virtual reality

5 Virtual Reality as Part of Risk Management Systems 

The mutual relation between ergonomics and safety related to the aging labour force creates space for utilization of VR and application of the technology in designing solutions for maintaining older employees in employment. 

Modelling a working environment using virtual reality helps design, in real time, a model reality that does not actually exist. This way, for the area of OHS, it is possible to analyze the existence or occurrence of hazards in the Man-Machine-Environment system at minimal cost and with no real hazard to health. 

The virtual reality application could be considered a new and progressive tool to be used in the risk management system. 

Virtual reality simulates a real or modelled environment that is possible to be visually perceived from the point of view of height, width, and depth, and as such, could provide a visual experience in real time, including sound, touch, and other forms

Furthermore VGInsight [16], a high-end tool for multi-volume and time-dependent volume raytracing is used for Virtual Reality inspection of the measured dataset. The package is running on a Quad-Pentium Pro System under the Linux Operating System. 

Another type of technology that has influenced oil and gas exploration is the acquisition of 3-U surface seismic data. This technology produces so much information that modern interpreters have been forced to give up looking at paper sections and use computers just to view their data. The 3-U seismic surveys are very much like a solid section of the earth. An interpreter can sit at a workstation and literally slice through the data viewing the seismic picture of the earth in almost cvci y way possible. Some companies have assembled virtual reality rooms where the... 

Among its many useful features is the ability to simulate both discrete and continuous CA, run in autorandoinize and screensaver modes, display ID CAs as color spacetime diagrams or as changing graphs, display 2D CAs either as flat color displays or as 3D surfaces in a virtual reality interface, file I/O, interactive seeding, a graph-view mode in which the user can select a sample point in a 1-D CA and track the point as a time-series, and automated evolution of CA behaviors. 

Some of those computers will be the thousands we access in the course of browsing the Internet. Others will be embedded in walls, chairs, light switches, cars, and even the human body. In short, pervasive computing is the antithesis of virtual reality. Instead of creating an artificial world inside the computer, it invisibly enhances the world that already exists. 

Nothing is quite what it seems in this fizzy, heady brew. Alchemy, tarot cards and cabbalistic theology mix with coincidence and quantum physics to create a world of virtual reality. .. the writing is often sharply, blackly funny"...

Finally, virtual reality technology will allow clients to do imaginal exposure virtually. For example, virtual programs can be written that allow the client to face (virtually speaking) all the tough and risky situations in session that they will face outside. They will be able to practice drug refusal skills, alternative ways to act, and new skills in the face of virtually exposed high-risk experiences. Virtual reality will provide a more realistic way to conduct exposure to cues... 

In the future, virtual reality may allow the operator to experience the environment. Special headsets and gloves may be used. After a com-...

Three-dimensional isovalue surfaces, corresponding to / = 0.08, were drawn from virtual reality modelling language (VRML) files produced by MOLDEN [il].

Figure 6.2 Virtual reality uses computer graphics to simulate the experience of being in a 3-D world. This type of therapy is used to treat phobias. By wearing a headset and entering a virtual world, patients can come face-to-face with their fears while remaining in a safe environment.

Process models are unfortunately often oversold and improperly used. Simulations, by definition, are not the actual process. To model the process, assumptions must be made about the process that may later prove to be incorrect. Further, there may be variables in the material or processing equipment that are not included in the model. This is especially true of complex processes. It is important not to confuse virtual reality with reality. The claim is often made that the model can optimize a cure cycle. The complex sets of differential equations in these models cannot be inverted to optimize the multiple properties they predict. It is the intelligent use of models by an experimenter or an optimizing routine that finds a best case among the ones tried. As a consequence, the literature is full of references to the development of process models, but examples of their industrial use in complex batch processes are not common. 

Since we follow an analytical, quantitative, and open-source computational approach, our pharmaceutical product/process and project management method and software toolset are implemented as (Internet browser readable) MS-Excel spreadsheets, integrated with several hyperlinks to the rule base and to optional 2D video and 3D virtual-reality objects for visualization.

There is a loss of contact with the outside world and a retreat into the virtual reality of the dream(y) state. 

So dreaming can be a good trip (ecstatic elation as in my second ski run is not uncommon) or a bad trip (with negative emotions like anxiety, fear, and anger always popping up). This means that dreaming is both heaven and hell (or that heaven and hell are virtual realities that are fabricated by us to mirror the virtual reality of our dream experiences). This... 

The practical example of real distribution systems is the natural gas supply network scheme offered by the Statoil corporation (Figure 3). In order to effectively build up this kind of distribution systems it is necessary to make use of the modular systems development results, and also to make use of the base of virtual reality simulation methodologies in order to prepare the architecture that responds to all requirements and needs of distributed systems. 

The next stage - from theory to practice in distributed system development - is to include logistics planning and material flow simulation (liquid or gas). Based on virtual reality simulation systems the integrated simulation system will combine the virtual reality and the material distribution network simulation. 

The integration of more sophisticate simulation systems like virtual reality systems is also possible. Electronic data management systems, that provide an integration platform for both the layout and the material-flow based data models, give an important contribution to the whole planning process. 

From the understanding of virtual reality as a virtual place of work -where the user can carry out all steps of development - interactive planning seems feasible within this environment. Prerequisite to this scenario is a real time simulation environment for the simulation of technological systems, particularly for distributed networks. One part of simulation model is based on a vertical flow of information, whereas another part of the model is based on the material flow (Figure 6).
