Rollercoaster of emotions! Vertigo sufferer has his family in stitches as he takes a virtual reality fairground ride

This is the hilarious moment a man who is scared of heights takes his first virtual reality ride on a rollercoaster. 

Paul Best from Bodmin, Cornwall, donned the Oculus Rift and was filmed by his brother Graham as he squealed, grunted and flinched during the immersive experience. 

Family members can be heard in the video laughing hysterically at Paul's reactions. 

His sister-in-law weeps with laughter as she stands behind him to make sure he does not fall over.

Mr Best, who is scared of heights, grunted and groaned while experiencing the virtual ride

Unlike a traditional video game the virtual reality headset 'fools' the user's brain into believing that the user is in the middle of the scenario. 

And Paul is clearly utterly convinced as he leans from side to side, grunts and groans as if being tossed around by the fairground attraction. 

Graham said Paul 'hates heights and fairground rides' but decided to stand up as he tried out the £299 Oculus Rift headset he had been given as an early Christmas present 

Graham added: 'My wife had to steady him to stop him from falling over.'

People using the VR headsets have reported crashing into television while trying to leap across the virtual scenario, forgetting they are still within the confines of their living room. 

The makers have warned that users could hurt themselves or become the victims of theft whilst they are using the devices because the goggles occupy a user’s entire visual field.
