Nuclear power stations use simulation to improve output by looking at temperature, pressure and gas flow in the plant.
Scientific experiments (for example plant growth) can be observed in varying conditions.
Coastal erosion (the effect of the sea on the coastline) can be studied to anticipate possible flooding, so that defences can be best positioned.
Traffic flow can be simulated in major cities to investigate the need for new roads and/or traffic lights.
The aerodynamic effect on the shape of cars can be investigated by simulating air flow over different body shapes.
Head-mounted VR display
Virtual Reality (VR) is a computer simulation which allows the user to interact with the system. Special interfaces give the user the feel, sound and view of the virtual system. The user wears a head-mounted display through which the virtual world can be seen.
