‘But currently there is no specific Guinness record, so I want to establish that.’

Because of his choice of game, he had to stay engaged and keep moving to create new drawings throughout most of the experience. 

For the challenge, which was completed on 7 April, Mr Westerman wore a HTC Vive.

‘The longest videogame marathon on a virtual reality game system is 25 hr 2 min and was achieved by Derek Westerman (USA) in Los Angeles, California, USA, on 7 April 2016,’ says the Guinness World Records website.

‘The virtual reality system used during this attempt was the HTC Vive and Derek played the game Tilt Brush for the entire attempt.’

Tilt Brush lets users paint in 3D space with virtual reality, using the room they are in as their canvas.

Instead of playing a traditional game, which might have made the time fly by, Mr Westerman used a painting app called Tilt Brush (pictured). Because of his choice of game, he had to stay engaged and keep moving to create new drawings throughout most of the experience

After the first half hour he had already starter to suffer.

‘Time’s passing pretty slow. I was starting to get extremely bored sitting down, and it’s scary to be extremely bored after a half hour.’

But two hours into the challenge he became more used to it. 

‘So at first it seemed really tedious being in here and I’m realizing the way to pass the time is to make little art projects,’ he said, after spending two hours in the headset.

HTC claims the Vive is ‘the first complete VR solution’ as it includes two wireless controllers (pictured), room scale movement sensors, the headset – complete with a built-in camera and phone – as well as two VR titles to play on it. The total package costs $799 (£555)

But the time spent in the VR headset took its toll. After 17 hours Mr Westerman was sick into a bucket (pictured) that he had used to pee into 11 hours previously. With four hours to go, he started to talk incoherently. ‘I don’t know where I’m at,’ he said. ‘All right, I’m freaking out a little bit’
