I have always dreamed about traveling, its my main passion along with photography. With oculus rift there will be content that that will allow me to virtually travel anywhere I want and with something like omni treadmill or any threadmill and motion detection I could actually walk in the plains of Serengeti or even Antarctica - in the footsteps of the guy or girl who has the camera attached to them or the robot etc.
I could go for a run in the morning in some exotic beach and in the evening stroll the streets of some city. I could hang out with a wolf pack or climb Everest with an expedition. I could be a virtual storm chaser close to a tornado and even travel deep in the ocean.
In fact these experiences will be so real, without risk, and of course cheap that I might actually have second thoughts about traveling... Antarctica without the cold... Jungles without the heat and bugs... And people who will provide these content will make millions.
While OR is a gaming device it has so much potential that its beyond comprehension as of now. Once the 'collective consciousness' is made aware of this little device and its available in shops, there will be an explosion of creativity that might actually change the world itself - no exaggeration intended, use your own imagination.
In the R&D offices of all major electronic companies, they're right now scratching their heads on how to make their own ORs and join this new VR revolution... In fact other uses of OR might in fact overshadow its humble gaming origins.
