The virtual-reality Oculus Rift headset has been put to a novel use by the Norwegian army - helping soldiers to drive tanks.

By mounting cameras on the outside of the tank, soldiers were able to create a 360-degree feed to the Oculus headset, worn by the driver.

The device - still just a prototype - is much cheaper than conventional military camera systems.

But the picture quality is not yet good enough for operational use.

The army began testing the headset in 2013 and in April of this year tried out the latest iteration of the hardware.
