Illustrate the Advantages of using virtual reality
- it's safer (As techniques can be tried out in advance without the dangers of real operation for example maintaining a nuclear plant where it is possible to try a task on a computer first to learn how to do it; if mistakes are made the results would be harmless; for example doing a medical task on a "virtual" patient is much safer in case of mistakes etc.)
- Cost savings (no need to build real thing that could save large sums of money for example testing out a real moon buggy or building a part of a chemical plant would be very costly).
- It's possible to do tasks which would generally be impossible (for example doing a task in outer space, walking inside a nuclear reactor etc.)
- There is a feeling of "being there" which makes the training more realistic and can allow some very realistic scenarios to be tested out for example how to deal with an emergency on a chemical plant which could be made to be really realistic!!
