I'd like to highlight an article of mine that was published a short time ago: all the truly good VR ideas were dreamt up in the 1960s.
The core of the article is to highlight that VR is a combination of simulation and interaction, and combining them effectively had to wait until the 60s, when the digital revolution and computers provided the right tools.
Here is an excerpt from my article:
I round out the article with a list of ideas from the 60s that happened, as well as listing some that have not happened yet. I also highlight the difference between "important" features, and "cool" ones.
Give it a read, and maybe you'll come away with some new ideas or perspectives on VR, and where it is going.
