Full Immersion VR?: Full Immersion VR is a theoretical technology you often find in fiction that has yet to be made into reality. Most commonly a player enters either a pod or wears a headset and lays down on a bed in order to interact with a game purely through brainwaves. This allows a player to enter a virtual world without any other form of input like a controller or keyboard.

Why doesn’t it exist?: Generally, it is because of the lack of technology to allow a computer to correctly interpret a person’s brainwaves to actions. Given that it uses the person’s brain to control everything, that really is the stumbling block from true virtual reality like you see in fiction.

If you want the most prominent example from recent years, that would be Sword Art Online’s NerveGear and AmuSphere technology. Honestly, it’s a pity that we have yet to achieve that and have spent time on pointless pursuits like the blockchain instead of pushing forward research to get to this piece of technology.

What about Web 3.0 and the Metaverse?: Well frankly the entire Web 3.0 experiment is kind of pointless in my eyes until we achieve true full immersion VR like we see in Sword Art Online. Maybe we will see it one day if we are lucky.
