What black technologies can only be seen in movies before have come into our lives?

Voice control technology

If you have seen early sci-fi movies, it is not difficult to find that the most high-tech in these movies is the voice control system. Compared with fingerprint recognition and iris recognition, voice control technology is more intuitive and does not need any special effects. Actors can control the machine by talking to it in the film. They have a strong sense of high-tech mystery. However, this technology appeared in American movies as early as 1920. In 1990s, IBM, Apple, AT & amp； T, NTT and other technology giants began to study voice control technology.

At the beginning of the 20th century, voice control began to be widely used in business. The most representative is Apple's Siri. When Jobs released the iPhone 4s, he also introduced Siri voice assistant. At that time, the iPhone 4s itself was a subversive mobile phone, and the "black technology" blessing like Siri added a lot of color to this product.

Of course, as the first Siri to push the voice assistant to a climax, when it was first applied to mobile phones, its functions were not perfect, and even many simple daily instructions could not be completed. Many users think Siri is just a gimmick and not practical. However, after several generations of product update iterations, Siri has become smarter and more powerful. Corresponding movies, such as the most classic "True Lies", the agent image starring Schwarzenegger; There is also Jarvis, an AI smart housekeeper who is omnipotent like Iron Man.

Iris recognition

In many sci-fi movies in the past, we can see that some top-secret documents or items are put in a safe, and thieves can open the safe and steal it just by aiming at an identification camera. Iris recognition is used in the movie because the movie itself adds some mysterious backgrounds and sound effects, which makes the whole scene look bursting with technology. Iris recognition technology only appeared in recent years. The related theories of iris recognition first began in 1930' s, but it was not officially commercialized until 90' s.

Iris recognition technology is to scan and image the iris pattern with infrared rays, and judge the similarity by XOR operation of the pixel bits of the pattern. Generally speaking, iris image acquisition, image preprocessing, feature extraction and feature matching are four processes. In the process of iris recognition, the iris will be separated from the eye image, and then analyzed and recognized. Because everyone's iris is unique and difficult to copy, in theory, iris recognition is safer than fingerprint recognition.

In reality, 20 15 Fujitsu of Japan has applied iris recognition technology to some mobile phones, but because of this, it has not formed the same trend as iphone5s fingerprint recognition. So far, the familiar mobile phones with iris recognition technology may still be Samsung Note7 and Samsung S8. In movies, we can often see the emergence of this technology. For example, in the famous movie Mission Impossible starring Tom Cruise, in addition to the exciting spy war, Tom Cruise needs to perform iris recognition and unlock every time he accepts a task in order to get a new task.

Fingerprint identification

The climax of fingerprint recognition appeared in iphone5s. As the benchmark of the mobile phone industry, iphone pushed fingerprint identification to the peak, which made most smartphone users think that iphone was the pioneer of fingerprint identification, but it was not. In fact, the first mobile phone in the world using fingerprint identification is the Motorola MB860 of 20 1 1 year. After 20 13, the iPhone 5s became a trend, and now it has become the standard of smart phones.

The use of fingerprint identification began in the field of criminal investigation. As early as 1960s, the US Federal Bureau of Investigation and the Paris Police began to develop and apply fingerprint identification technology. After a long time, because fingerprints can be carried for a long time, due to the particularity of fingerprints, it can be said that it has made great contributions to solving the case. However, with the continuous maturity and commercialization of this technology, more and more technology products are equipped with fingerprint recognition, such as company employee cards, access control and even notebooks.

Commercial applications have further promoted the popularity of fingerprint identification technology, which has also experienced several generations of evolution and become more and more mature in smart phones. Even though fingerprint identification is not a new technology now, we can still see the application of this technology in many movies. For example, the fingerprint identification technology used by Schwarzenegger in the movie The Sixth Day, and the fingerprint identification effect demonstrated by Nicolas Cage in The Island of Death and National Security.

Virtual Reality/Augmented Reality Technology

When it comes to what is the hottest in the science and technology circle in the last two years, everyone will undoubtedly think of virtual reality VR and augmented reality AR. AR and VR have now entered people's lives and can be seen in many places. The so-called virtual reality technology is to simulate the three-dimensional feeling with a computer, and then convey the information of the virtual world to the experiencer more naturally through the equipment, so that the brave can achieve the immersive feeling. Augmented reality, on the other hand, embeds the virtual world into the real world and interacts with it, thus "enhancing" the reality.

In the mobile phone camp, there have been rumors that the iphone8, which is highly anticipated by fruit powder, will be an AR mobile phone. In the mobile phone industry, there is no VR mobile phone. In the fashion market, there is a VR mobile phone called Bao Li Qian Daling. The VR lens module of this mobile phone has a pixel value of 26 million and uses SonyIMX258 photosensitive element. The thickest part of this lens module is only 23.8mm, which is the thinnest mobile phone VR lens module in the world. Through Bao Liqian, the VR mobile phone can take 360 panoramic shots, generate VR content anytime and anywhere with one click, and preview, edit and share it in real time.

As far as the current products are concerned, even those mobile phones equipped with VR and ar technologies can't be compared with independent devices, and they still have certain disadvantages in experience. However, the outbreak of the mobile Internet is bound to make VR mobile phones become the trend of future industry development. On the other hand, in movies, many scenes are realized by these technologies. For example, "Avatar" is made by VR virtual reality technology to show you the internal operation of the spaceship, while in "Iron Man", after Iron Man wears steel clothes, the interface inside the helmet is realized by augmented reality technology.

Artificial intelligence robot

In this movie, there are three particularly powerful robots. In fact, it seems to be an artificial intelligence robot now. The most impressive of the three robots is TARS. Under normal circumstances, the taser is a square box, but compared with the current robot, it can also switch freely between liquid and solid, with efficient cognitive ability and strong deformation ability. Especially when Dr. Brand is hit by waves on the water planet, Tass can quickly deform and move to save lives.

The most famous name of this robot is Alpha Dog. In the process of playing chess with robots, Ke Jie, a master of Go, lost all three games. Of course, South Korean player Li Shishi also played against Alpha Dog last year, and also lost the game. Although Li Shishi pulled back a game in the middle, it didn't help the result. After the game, some netizens joked that the horror of Alpha Dog is not that it can win the game, but that it actually releases water during the game. That's the most terrible thing.

Of course, domestic artificial intelligence robots are also developing, and small robots are on the scene. Since the advent of 20 14, small robots have been unknown until they stepped onto the stage of super brain and let the public know that there are such powerful robots in China. Of course, as far as the current technology is concerned, it is not enough to make a real deformation robot. However, American researchers have discovered the rare metal indium gallium alloy.
