Will the NerveGear ever exist?
While an exact real-life manifestation of the iconic NerveGear from Sword Art Online remains well out of reach today, the astonishing pace of technological advancement means certain key aspects of full dive virtual reality could manifest within 20 to 30 years. However, significant obstacles around hardware limitations, medical risks, and replicating real-world physics mean that even by 2050, VR may remain far from matching Kayaba Akihiko‘s dangerous invention.
The surging popularity of virtual reality
The virtual reality industry has exploded since the first Oculus Rift developer kit launched in 2013. By late 2022, an estimated 15 million VR/AR headsets were in use globally. Revenue in the VR gaming hardware & software market alone is expected to grow at a 42% CAGR from 2022-2030, reaching over $53 billion. Major players like Meta and Sony also plan to release new high-end VR systems in 2024, hinting at a new stage of consumer adoption.
With insatiable gamer demand for ever-more immersive experiences, VR technology is progressing extremely quickly. But current headsets remain highly constrained compared to Sword Art Online‘s imaginative NerveGear.
Obstacles to achieving full dive VR
| Hardware Constraints | – Limited field of view <90° in even top headsets
– Inadequate resolution for natural eye focus
– No mass-market solution for eye tracking, body tracking, facial tracking |
|-|
| Haptic Limitations | – Lack of compact solutions for realistic touch feedback
– Temperature, texture simulation major challenges |
| Health Risks | – Motion sickness from locomotion techniques
– Long-term issues like eyesight damage |
Based on the above, it‘s reasonable to conclude that while incremental improvements will continue, current mainstream VR technology likely sits at least 10-15 years away from providing completely natural, safe full dive experiences comparable to those depicted in anime like Sword Art Online. Significant hardware advancements around display resolution/FOV, motion input, graphics rendering, and haptics would need to be made and integrated affordably at consumer scale.
However, novel innovations sprouting up across various technological domains hint that certain integral components of a "NerveGear" could materialize sooner than one may expect…
Cutting-edge technologies bringing full dive closer to reality
While widespread skepticism exists even among VR pioneers about whether exact NerveGear-style tech will ever emerge, remarkable new solutions demonstrate that certain facets are rapidly crossing over from science fiction to reality:
Direct neural interfaces lead the charge
Elon Musk‘s Neuralink has successfully used a brain implant to enable a monkey to control a computer with its mind alone. Facebook is also developing a wrist wearable capable of interpreting nerve signals from the skin. These early innovations prove that direct brain/neural connection for VR control could become viable within 5-7 years if development momentum continues.
Haptic gloves closing the tactile gap
Haptic gloves like HaptX and the Dexmo Exoskeleton now feature over 50 touch points along the hand and excel at Psi (pressure) feedback – a key sensory input missing from current VR. While still bulky, by approximating realistic physical interaction, these devices represent important steps towards replicating touch in virtual worlds. Applied at scale, they could help manifest the NerveGear‘s promise of feeling objects in-game.
Cloud rendering and 5G enable persistent worlds
Cloud gaming services like Google Stadia can now stream graphically rich games to low-power devices thanks to remote servers handling rendering. And lightning fast 5G data networks will soon eliminate lag and allow persistent VR spaces like NerveGear games to be accessed anywhere, anytime.
Combined with smartphones gaining processing power rivalling gaming PCs, cloud-streamed environments displayed in mobile VR headsets could soon let users stay immersed indefinitely – no logout required!
Expert predictions on full dive viability
Technology luminaries like Michael Abrash of Oculus predict that by the early 2030s, AR/VR devices may match visual capability with the human eye while advanced neural input solutions enable intuitive control.
VRFocus 2022 industry research also notes that "more widespread adoption of BCI (Brain Computer Interfaces) for VR control and feedback seems inevitable in the long term".
Does this mean true full-dive VR is coming? Not so fast. Serious hardware constraints and simulated world limitations will still take many years to sufficiently address. But innovators forecast that by 2040-2050, headsets providing 70% of the mainstream full-dive VR experience depicted in futuristic anime may hit the consumer market, with VR possibly rivaling physical reality decades beyond that.
The trail towards realizing such an immensely complex endeavor however remains filled with challenges. Only the coming decades will tell just how far our species can transport virtual reality. But from what we‘ve achieved in the last 10 years alone, I have hope that VR developers continue pioneering solutions bringing the dream of the NerveGear inch by inch closer to mankind‘s grasp!
