Now to the example of urgency, i see what you mean, but if you stand close to the TV screen the sense of falling will be higher aswell. Yeah, you are tricking your brain, but its still far from beeing a VR experience. Its albeit a very limited one. So limited that i dont see the point, especially when weighed against health and confort issues.
The idea that a fully realized holodeck is the only thing that can be considered VR is a bit limited.
Like saying that in order to be considered a house, you must have 3 bedrooms and 2 bathrooms at least.
2 bed rooms and 2 bathrooms isn't a house, because that's your definition.
Disagree about the first bolded, I haven't really had that same sense with TV. TV always feels like a gate to another reality, but there's still a separation.
Second bolded, I'm not sure what you mean.
Yes, there are limitations to current headsets, but it doesn't mean that it's not VR.
