Also reading the comments I see someone saying their father is disabled and this would be a great way to give him the feeling of freedom again. I never really considered uses outside of gaming, but if it could be used as some sort of therapy too then that's fantastic.
Another area is medical.
I know already surgeons can take a virtual tour of a body organ for example, before they operate.
That's a good one. I know they have been experimenting with using robots for surgery controlled by a surgeon thousands of miles away and OR could help there too.
I would imagine the armed forces would have a good few uses too (remote vehicle control, bomb disposal).
