Nvidia used part of founder and chief executive Jensen Huang's keynote presentation at the company's GPU Technology Conference to give a live demonstration of an autonomous vehicle being controlled by a remote human operator.

The project is based on the idea that we want humans to be the backup controllers of autonomous systems, but there will be times when nobody is physically present, he explained.

This isn't about taking over in an emergency, but rather coping with a situation where a car has come to a halt because the onboard system can't work out what to do next.

The car was initially stationary behind a parked truck. The driver took control, moved off, steered round the truck and into a nearby car park, slotting the vehicle neatly into a vacant space at the first attempt.

The demonstration was performed in a private area that was closed to the public at the time.

VentureBeat shot this video from the floor of the auditorium:

After the demo, the driver told journalists that there was a short break in the main video feed from the car as he entered the parking lot.

Huang said this technology means "we can go somewhere that we otherwise couldn't".

It shows how VR can be used "to teleport ourselves into the mind of the autonomous machine."
