VR technology is good at fooling visual and auditory perception, and has made great strides in these areas over the past decade. But when it comes to tactile perception, it’s still largely limited to vibrating controllers, which is a decades old idea. There are VR vests and treadmills, but they are technically quite primitive and not worth the effort for most people.
Ready Player One gives the impression that the OASIS is a parallel world in which you physically participate similarly to the natural world. But the book and the movie don’t explain how this is done technically. Even if we had sophisticated haptic suits and treadmills like in the movie, interacting with virtual worlds would not seem as natural as it does for the protagonists in the OASIS.
Something like this could only be possible with a sophisticated brain-computer interface that somehow enables sensory hallucinations. But this is a dystopian idea more reminiscent of The Matrix than Ready Player One, and infinitely further away in terms of feasibility than archaic technologies like haptic suits and treadmills.
Virtual reality as a gateway to a hyper-realistic parallel world: this is an effective sales concept, but it has little to do with reality. Most people are aware that they are wearing VR headsets when they play games. They are consciously using their real bodies and enjoying it. And they are happy to return to reality after a while. After all, it’s still the best place to cuddle or have a pizza.
I think the term “virtual reality” promises more than it can deliver and may even be based on a misunderstanding. Humanity has developed a wide variety of immersive techniques throughout its history: from the art of storytelling and the cave paintings of Lascaux to film and virtual reality. I believe the latter is just another point in this evolution, not its conclusion.
Just because virtual reality can deceive our visual and auditory senses even more than before, it is not necessarily predestined to become a fully immersive technology. In fact, I believe that in the future, virtual reality will be just one of many, and by no means the most common, application of face computers. And that’s perfectly fine.
The book has a lot of parts in it that hint that the haptics weren’t really all that realistic, but the visuals and audio were very very good. Controls were hand gestures and I would expect standardized.
I think we’re not all that far from what the book describes in the beginning. At least as far as individuals hardware.
As far as lag minimized connections and interfacing with multiple users all at once… yeah that’s handwaving and I feel we’re far from having a system that has near the “capacity” described in the book.
