Demonstrate and apply knowledge and understanding of how virtual reality is used in the following applications:
− training; and
− gaming.

Virtual reality:
A system that enables a person to react and move according to certain simulated conditions
Simulation:
A program which models a real life situation by putting values into a model to see how it behaves in different environments.

VR Equipment
• Helmet
• Gloves
• Bodysuit

• Games
• Holiday tours
• Combat situations
• Historical recreations

• Helmet sometimes called a Head Mounted
Device - allows 3D visual hearing
• Glove for sensations of touch to allow the control of the model

• A device that goes on the end of the finger and senses simulated movement

Advantages
• Eliminates the danger
• Less expensive than using a real plane
• Helps give the pilot experience of a real environment
Disadvantages
• The training can only be as good as the program

Advantages
• Can add to the gaming experience such as having animated people with various attributes
• Visual, sound and sensation effects can be added
Disadvantages
• The person can start believing in the unreal
• The equipment to play the games is sophisticated

• VR: Virtual reality
• HMD: Head Mounted Device
