Virtual Reality is one of the biggest players that will gain more and more interest in the near future. This project will be huge!
But its definitely long term project, because technology needs minimum 1 year till ready for the masses, also hardware has to become cheaper.
I checked now in my country and you can buy VR glasses at 118 $. So its not so expensive.
And the price is only going to get cheaper, especially relative to the technology. Think about your phones, computers, etc. The technology is WAY better than 5 years ago, but the price is way cheaper than it would have cost for the same specs.
For the PCs they are expensive now but for phones you can find a cheaper one .
Ex: in my country: Samsung Gear VR SM-R322 is 93.81 $
Samsung Gear VR SM-R323 + Controler is 145.41 $
Samsung Gear Controler is 62.54 $
And for Other Phones you can find it cheaper ... depends of the glases(they are betwen 20-1000. Ofcourse you can find expensive glasses to ... but Who want use them in this porpouse like this project i think anyone can aford it.
