Being Like Kirito and Asuna in the Real World

Have you ever tried—or at least seen—the thrill of playing with a Virtual Reality (VR) device? This sophisticated device seems like a magic door, allowing us to jump in and interact directly within the game world.

However, behind all its marvels, there's one significant and unfortunate drawback. Modern VR devices still heavily rely on the user's visual acuity and physical stamina.

So, what if we look to the future, or more precisely, delve into the world of fiction? For fans of novels or anime, the title Sword Art Online (SAO) must be very familiar.

In that story, there are revolutionary devices called NerveGear and AmuSphere, used for full immersion into VRMMO (Virtual Reality Massively Multiplayer Online) games.

In the SAO story, NerveGear is the first-generation FullDive device. Unfortunately, this device is extremely dangerous because it emits microwaves that can fry the user's brain if they die in the game, or if the helmet is forcibly removed from the outside.

How AmuSphere Works

AmuSphere operates with a highly futuristic mechanism: it temporarily blocks central nervous signals from the brain to the physical body, then fully transfers the user's consciousness into the virtual world.

Even more incredibly, this device is designed to trick the human nervous system into fully replicating all five senses.

This is where the true, often-forgotten magic lies. If technology like AmuSphere truly becomes a reality, it would no longer be just a luxury toy for gamers, but a grand gateway to equality for people with disabilities.

For the Visually Impaired

Those who are blind, deaf, paralyzed, or have other physical disabilities could once again see clearly, hear friends' voices, walk upright, run fast, and even fly freely within the virtual world.

This technology would tear down thick walls of discrimination and open up truly equal employment opportunities.

People with disabilities could pursue professional careers in the virtual world as programmers, content creators, designers, and even virtual esports athletes, just like people without disabilities.

In the Field of Healthcare

In the field of healthcare, this device could even become a revolutionary medical therapy for severe stroke patients or those experiencing total paralysis (locked-in syndrome), allowing them to interact and socialize with the outside world again.

The good news is that the development of technology in this direction is not mere fantasy.

Scientists and global technology companies are racing to develop Brain-Computer Interfaces (BCI), such as the research currently being undertaken by Neuralink.

Coupled with Leaps in AI Technology

Coupled with the rapidly advancing leaps in Artificial Intelligence (AI) technology, the realization of FullDive devices is not impossible for us to witness in our lifetime.

The challenge for scientists now is simply how to make such devices practical to wear on the head like a headband without requiring medical surgery, while also ensuring the privacy and security of our brain data so that users' thought signals are not easily hacked or misused in the virtual world.

However, there's one crucial piece of advice to remember: if devices like NerveGear or AmuSphere are ever commercially released in the real world, don't rush to buy them on day one.

Wait Patiently for About One or Two Years

Wait patiently for about one or two years to ensure there are no manufacturing defects or undesirable issues.

Furthermore, the initial release price will undoubtedly be very expensive and drain your wallet.

After all, we still need to be vigilant and cautious, just in case a life-or-death game tragedy à la Sword Art Online actually happens in the real world.

Unless, of course, you genuinely intend to be a hero and want to become the next Kirito or Asuna.
