Virtual Reality

Virtual Reality (VR) is a type of spatial computing where users are fully immersed in a virtual world. The eventual goal of Virtual Reality is to wind up at a stage where the players are completely and totally immersed in their fantasy so as to not know that they took a "deep dive" into something that was VR.

There are many ideas like this one in fiction. One that is brought up quite a bit in pop-culture is [https://matrix.fandom.com/wiki/Construct#:~:text=From%20clothing%20to%20equipment%2C%20weapons,operatives%20hack%20into%20the%20Matrix. The Construct]" from The Matrix. Another is .hack And one other is S.A.O. (Sword Art Online).

These virtual worlds all do not allow, free-movement, IRL. This is called a "Full Dive" Simulation.

Interesting concepts:

To quote from the Sword Art Online Wikia:

"The «World Seed» (世界の種子, Sekai no Shushi?), is an item that holds a program package called «The Seed» (ザ・シード, Za Shīdo?). The Seed is a free, preset series of program packages that can be used for creating Virtual Reality (VR) worlds as well as control the input and output of the five senses of the players, allowing players to FullDive into the created world. The Seed was created by Kayaba Akihiko and replaced usual proprietary game systems, like the Cardinal System that Akihiko had developed while working for Argus and which was required to run VR games, but had a terrifyingly huge license fee."

To quote, from Morphious, on The Matrix Wiki:


 * "This is the Construct. It's our loading program. We can load anything... From clothing to equipment, weapons, training simulations; anything we need."
