•La realtà virtuale (VR O RV) è una tecnologia che consente di ricreare, tramite computer, mondi e oggetti che sono la trasposizione digitale di ambienti reali o di fantasia. •RV è un modo per visualizzare, manipolare e interagire con dati estremamente complessi per mezzo di una simulazione che, in ambienti immersivi, viene percepita totalmente dai nostri sensi, in particolare dalla vista, seguita dall’udito e dal tatto.

DEFINIZIONIIntroduzione alla RV


•Utente sceglie• Interazione•Realismo (rendering: resa realistica degli oggetti rappresentati, real-time)

• Immersività, senso di presenza (I/O video/audio)

•Cooperazione (Telepresenza)

PECULIARITA’ Differenze con la grafica tradizionale (CAD)

APPLICAZIONIIntroduzione alla RV


- Decision-making collaborativo- Penetrazione su problemi complessi

- Costi di produzione e di lavoro- NON PRATICABILITA’, danno e spesa ambienti fisici reali

- Dimostrativi di prodotti- Acquisizione di capacità e apprendimento dei concetti

- Esplorazione intuitiva

Halden VR Centre

VR Centre was established in 1996 The activities started out as

Bilateral IFE projects work for Norwegian and international industry

VR research increasingly more important

Use of Virtual Reality in Control Room Engineering (CRE)



Why Use VR in CRE?

Costly physical mock-up not necessary Design can be modified quickly and easily

to prototype different solutions in a short period of time

Can evaluate a design against ergonomic data, guidelines and recommendations

Save time and money in addition to a more optimal design solution

Scenarios

In a Scenario one or more manikin workers

perform work tasks inside the NPP.

In order to distinguish between workers,

each gets a different colouring either on

the suit or the helmet.

Each worker also has a name and a

description that can be edited by the user.



Camera View

The user can view the scene from a virtual camera…



Manikin View

..or from the eyes of one of the manikins.



Manikin View with radiation Information



Radiation Landscape Visualisation

A surface plot of the dose-rate in the area around the spectator is also provided.

The data in this plot are measurement interpolations at the chest (dosimeter) height of a person viewing the model from the virtual camera’s position.



Scenario Recording

A scenario is recorded as a set of routes with action markers. Each of these

routes or work tasks belongs to a manikin.



Playback of Scenarios

On playback the manikin will walk the route as recorded, doing work or handling objects on the

markers where the user has recorded such actions.

The manikin is also pausing on markers where it has been synchronized to wait for other manikins to

finish their tasks.



Scenario CreationLe attività di Halden - VR-Dose


The Dose-Rate of a Work Task

In the scenario recording, routes with markers of positions and duration at each position are generated.

These routes may afterwards be assigned to real life workers from the system worker database.



The Database InterfaceLe attività di Halden - VR-Dose


Libreria di oggetti

A bank of decommissioning tools is being made. These tools can be inserted into the Fugen model and used by the manikins in the scenarios.

Examples:



Taglio di oggetti

In a dismantling process, cutting of various large objects will be necessary. This is a complicated task in VR, and a module for cutting pipes is being made this year.



VRDose e ambiente di progetto

A more user friendly interface is under development.

In the decommissioning project, JNC will use the planning and work estimation system “COSMARD” by JAERI. The new user interface of VRdose will try to reflect the COSMARD work breakdown.

Based on COSMARD, a wizard for scenario recording will help the user to enter information into the system.
