Unlike ordinary science fiction works, the discussion of technology in this book is basically traceable. Pen ~ fun ~ pavilion www.biquge.info so it's not exactly black technology in the standard sense.

1. Deep immersive VR

Chapters 8 and 69 are described in a concentrated manner. It's not about VR, it's about immersion. The audio-visual sensation can be provided by a VR headset, which is already a relatively mature technology. The discussion here is about the creation of the sensation of touch, force, and gravity.

2. Gaze tracking focus technology

Chapter 10 is explained by the Tianshan Snow Lotus. It is a technology used to solve the dizziness caused by 3D display. However, the implementation of the methods mentioned in this book depends on the speed of feedback from the entire optical system. At least the reaction speed of the existing cameras is not enough.

3.AR glasses

Appears in chapters 97-99. The implementation of this technology is not a problem now. However, whether it is possible to present virtual images in the real plane requires more technological breakthroughs.

4. Intelligent prosthetics

Appears after chapter 120. It is now partially possible to have the prosthesis receive direct control from the nervous system and feedback sensory signals to the body. The main problem is whether the prosthesis can be controlled in a subtle way and make the prosthesis produce a full range of sensations, and whether the artificial skin can achieve the level of realism in appearance.

5. Regeneration of severed limbs

It is expected to be after two hundred and fifty chapters. It is essentially a combination of cloning techniques and amputated limb replantation. The key is to control the regenerative process and whether the fast-growing limb can cause damage to one's immune system. However, it is believed that there will be clinical applications in the near future.

6.AI

This book, like almost all works about artificial intelligence, is written with virtual AI characters as if they were real people. It's like they've all passed the Turing test. As for the extent to which it can be achieved in reality, no more consideration has been given.
