From Gamesmold:
In February 2014, I approached the german roller coaster manufacturer Mack Rides with the idea of extending a real roller coaster by wearing an Oculus Rift headset during the ride. I was wondering if it would be possible to replace the real environment by a synchronized virtual ride.
At Mack Rides, they also saw the potential and entered this ground-breaking cooperation project with me and my students, providing us two roller coasters for research and testing (I’m working as a professor at the University of Applied Sciences Kaiserslautern).
Then, on April 7th, we actually became VR coaster pioneers – being the very first people to experience an Oculus Rift VR-ride on a real roller coaster, synchronized to the real track. And it was just unbelievable! On that day, we all felt that we were laying the foundation of something very big.
