VR (Virtual Reality), virtual reality

First of all, let’s talk about this VR, VR is virtual Reality, virtual reality technology is a computer simulation system that can create and experience a virtual world. It uses computers to generate a simulated environment. It is an interactive three-dimensional dynamic vision and entity behavior system simulation that integrates multi-source information to immerse users. into that environment. The *R technology launched by VR brings humans into a "three-dimensional" information perspective. Through *R technology, we can watch the digital records of the world from all angles, watch news, watch games, watch movies, watch beauties... The digital world and The convenience of the physical world has been blurred by AR technology (augmented reality). We are in a world where bits and atoms are mixed. This will completely subvert the many ways we obtain information, generate information, interact with the world, and produce products, just like computers once changed the world. It sounds exciting. VR consumer devices can now be divided into three categories: Oculus Rift, a head-mounted device that needs to be used with a computer, which is not yet commercially available; VR conversion brackets that project mobile phone content, such as Baofeng Magic Mirror and CardBoard; bring your own host without a computer or mobile phone, etc. Peripheral VR all-in-one machine. There are also professional VR content production equipment such as Nokia OZO.

AR (Augmented Reality), augmented reality

AR is augmented reality, augmented reality technology (Augmented Reality, AR for short) is a real-time calculation of the position and angle of camera images And coupled with the technology of corresponding images, videos, and 3D models, the goal of this technology is to set the virtual world in the real world on the screen and interact with it. This technology was proposed in 1990. With the improvement of CPU computing power of portable electronic products, it is expected that the use of augmented reality will become more and more widespread. The most typical AR device is Google Glass (the Chinese equivalent is BaiduEye). When you stare at a restaurant, it will help you retrieve relevant information and display it. When you stare at a beautiful woman, it will display her measurements, similar to this application. . If we use a mobile phone to take pictures and then perform image search or PS operations, does it count as AR?

The difference between VR and AR:

To put it simply, in virtual reality (VR), the scenes and characters you see are all fake. It puts your consciousness into a virtual world. world. Augmented reality (AR) brings virtual information into the real world. Some of the scenes and characters you see are real and some are fake.

Interaction differences:

VR equipment: Because VR is a pure virtual scene, VR equipment is more used for the interaction between users and virtual scenes. The more common uses are: Position trackers, data gloves (5DT and the like), motion capture systems, data helmets, etc.

AR equipment: Since AR is a combination of real scenes and virtual scenes, it basically requires a camera. Based on the pictures captured by the camera, it is combined with virtual pictures for display and interaction, such as GOOGLE GLASS (actually strictly Generally speaking, IPAD, mobile phones and other products with cameras can be used for AR, as long as AR software is installed)

MR (Mix Reality)

< p> The definition of MR is: mixing the real world and the virtual world to create a new visual environment. The environment contains both physical entities and virtual information, and must be "real-time". The two representative devices of MR are Hololens and Magic Leap. Mixed reality (MR), including both augmented reality and augmented virtuality, refers to a new visual environment created by merging the real and virtual worlds. Physical and digital objects exist in the new visualization environment and interact with each other in real time.

The system usually adopts three main characteristics:

1. It combines virtual and reality;

2. In virtual three-dimensional (3D registration);< /p>

3. Run in real time.

CR (Cinematic Reality), imaging reality

This is a concept proposed by Magic Leap invested by Google. It is mainly to emphasize the difference from VR and AR technology. Similarly, it believes that it is different from VR and AR technology. MR is also different. In fact, the concept is similar. It is the convenience of blurring the physical world and the virtual world. The tasks completed, the scenarios used, and the content provided are similar to MR products. The core of CR is that through the design of light wave conduction prisms, Magic Leap projects images directly onto the user's retina from multiple angles, thereby achieving the purpose of "cheating" the brain. That is to say, unlike screen projection display technology, this technology can achieve a more realistic impact and directly interact with the retina, solving the problems of Hololens' narrow field of view or dizziness.

AI is artificial intelligence, not a wearable device. Artificial Intelligence (Artificial Intelligence), the English abbreviation is AI. It is a new technical science that studies and develops theories, methods, technologies and application systems for simulating, extending and expanding human intelligence.

Artificial intelligence is a branch of computer science that attempts to understand the nature of intelligence and produce a new intelligent machine that can respond in a manner similar to human intelligence. Research in this field includes robotics , language recognition, image recognition, natural language processing and expert systems, etc. Since the birth of artificial intelligence, the theory and technology have become increasingly mature, and the application fields have also continued to expand. It can be imagined that the technological products brought by artificial intelligence in the future will be the "containers" of human wisdom.

Artificial intelligence is the simulation of the information process of human consciousness and thinking. Artificial intelligence is not human intelligence, but it can think like humans and may even exceed human intelligence.

Artificial intelligence is a very challenging science, and people engaged in this work must understand computer knowledge, psychology and philosophy. Artificial intelligence is a very broad science, which consists of different fields, such as machine learning, computer vision, etc. Generally speaking, a main goal of artificial intelligence research is to make machines capable of tasks that usually require human intelligence. Complex work. But different times and different people have different understandings of this "complex work".
