Inventory of technology from science fiction movies to reality

  Many scenes, technologies, and products that were originally considered unthinkable in science fiction movies are becoming reality step by step, such as humanoid robots, driverless cars, and hoverboards, which are quietly changing our lives.
  ”The Hitchhiker’s Guide to the Galaxy”: universal translator
  in Garth Jennings directed the sci-fi movie “The Hitchhiker’s Guide to the Galaxy” (adapted from the novel by Douglas Adams), there is a magical little fish called the “Babel Fish.” It is parasitic in the host’s ears and lives on the brain waves of the people around the host. It can automatically convert the brain waves of the surrounding people into the brain waves of the host, so the host can understand any language.
  Although this fish does not currently exist, SIGMO may be able to replace it. SIGMO is a compact interpreter with a built-in microphone and amplifier. It is connected to the mobile phone via Bluetooth, and can call “Google Translate” and other application programming interface (API) for translation, and then synthesize the translated speech with speech synthesis software, and finally transmit the audio to the mobile phone through the mobile phone network.
  At present, this software can automatically recognize 25 languages, translate and pronounce, and completely solve the problem that people cannot communicate with people who do not understand the language. SIGMO is small and portable, it can be clipped on clothes or belt, beautiful and practical.
  ”Star Wars V: The Empire Strikes Back”: A mechanical prosthetic controlled by mind.
  ”Star Wars V: The Empire Strikes Back” was directed by Irving Kershner and was released in May 1980. The protagonist of the film, Luke Skywalker, unfortunately lost his right hand during the battle with his father Darth Vader. Fortunately, in the movie, a high-tech prosthesis was connected in time.
  This technology has now become a reality. In May 2014, the intelligent prosthetic DEKA system arm, comparable to the advanced prosthetic arm of Skywalker in “Star Wars V”, was approved by the US Food and Drug Administration (FDA) for clinical use.
  This prosthetic arm, also called “Luke Arm”, is a tribute to “Star Wars V” and was developed by DEKA at a cost of 40 million US dollars. The U.S. Department of Defense Advanced Research Projects Agency (DARPA) began funding this project in 2005. It was initially used by soldiers who were disabled due to the Iraq War. Later, it also provided technical assistance for people with varying degrees of arm loss.
  The “Luke Arm” is close to the weight of a human arm. It is driven by a complex sensor and motor group. The EMG signal on the muscle is collected first, and then the movement information is interpreted by the built-in microcomputer, and then converted into action. This arm can be unlocked with a key, and it can also pick up coins, fruits, paper and other small things very steadily. It has a higher fit with the human body and greatly improves the comfort of use. Traditional prosthetic limbs are not the same.
  ”Minority Report”: Driverless cars
  In 2002, the sci-fi blockbuster “Minority Report” directed by Spielberg and starring Tom Cruise is a textbook of driverless car technology. In the movie, the cars on the urban transportation line in 2054 are all controlled by a computer network. Drivers only need to inform the cars of the destination they are going to reach. In addition, there are also driverless cars in movies such as “Me, Robot” and “Knight Rider”.
  Currently, there are real-life driverless cars. On December 22, 2014, Google launched its first fully automated driverless car prototype. This car does not have a steering wheel, accelerator, brake pedal or gear shifting device, and is driven entirely by software and sensors. Google believes that computers are less likely to make mistakes than human brains. The popularization of driverless cars is expected to make traffic accidents completely a thing of the past, and it can also protect the environment by reducing car usage.
  On March 22, 2015, an unmanned Audi Q5 utility vehicle left the Golden Gate Bridge in San Francisco on the west coast of the United States and headed to New York on the east coast for a total distance of approximately 5,600 kilometers. This is the driverless car with the longest driving distance so far. Today, companies such as Audi, Toyota, Mercedes-Benz, and Google are all trying to make driverless cars.
  The states of Nevada, Florida and California have passed legislation allowing driverless cars to be legally used on the road. However, experts believe that unmanned vehicles still face many obstacles such as technology and law, and it will take some time before they are truly on the road on a large scale. However, the Institute of Electrical and Electronics Engineers (IEEE) predicted that by 2040, 75% of the cars on the roads around the world will be driverless cars.
  ”Changing Face”: Face Transplant
  In 1997, in the film “Changing Face” directed by Wu Yusen and starring Nicholas Cage and John Travolta, the protagonist and the villain changed faces as simple as changing their masks.
  So can you change your face like this in real life? When the movie was released, face transplantation was not possible. Now more than ten years have passed and the situation has changed. In 2005, the world’s first face transplant operation was performed. The patient was a French lady who was bitten by a dog and had to undergo partial face transplantation. In March 2010, Spanish farmer Oscar received the world’s first full face transplant. In May 2013, Poland performed the first full face transplant for a 33-year-old man whose face was cut off in a stone cutter accident. The operation took 27 hours and the patient’s physical condition was stable after the transplant. In 2014, a man in the United States appeared in a fashion magazine after undergoing a full face transplant. So far, 27 face transplants have been performed globally, of which only 4 have failed. However, face transplantation is not as simple as the one shot in “Face Changing”. In order to prevent the transplanted face from being rejected by the immune system, people undergoing surgery have to take immunosuppressive drugs throughout their lives.
  ”Metropolis”:
  The silent film “Metropolis” directed by Fritz Lang in 1927 sets the background in the sinister 2026. In the movie, the humanoid robot played by Bridget Hulme is crazy Developed by the scientist Luo Hong.
  Such a grotesque humanoid robot is the first monument in the history of sci-fi movies. From the clone in Blade Runner (with the same intelligence and feeling as humans) to the robot boy David in Artificial Intelligence, etc. The image in “Metropolis” is an embryonic form.
  In fact, scientists have developed many humanoid robots. In June 2014, the largest humanoid robot exhibition to date was held at the Museum of the Future of Science in Tokyo, Japan, including female announcer robots, adult female robots and child robots. Their appearance is almost the same as ordinary people, and some can even be Communicate with visitors. They are the result of more than 20 years of hard work by Japanese roboticist Hiroshi Ishiguro. What is the future development of humanoid robots, let us wait and see.
  ”Eternal Sunshine of the Spotless Mind”: memory manipulation
  in 2004, Michel Gondry’s film “Eternal Sunshine of the Spotless Mind”, the Clementine Crowe Chomsky (played by Kate Winslet) and Joel Barris (played by Kim Carey), the couple, because they were tired of quarreling, went to the “forgetfulness clinic” to eliminate each other’s memories of each other.
  In fact, in recent years, the scientific community has been studying the technology that can eliminate memories in the “forgetfulness clinic”. In 2011, scientists at the Human Stress Research Center of the University of Montreal in Canada discovered that by inhibiting the secretion of glucocorticoids, it can help patients eliminate painful memories. According to a British media report in October 2013, scientists from the Massachusetts Institute of Technology in the United States said that they have discovered a gene Tet1 that can erase memories. If they can find a way to improve the activity of this gene, it will give people with “phobias” Bringing the gospel will even change the destiny of mankind.
  In March 2014, Dutch scientists announced that they had successfully used electric shock therapy to delete designated memories in the human brain. Volunteers have forgotten the painful past after conducting the electric shock treatment experiment, but the good memories have not been damaged.
  A report published on the website of the British “Nature” magazine on August 27, 2014 stated that Japanese and American scientists have successfully developed methods to rewrite memories, which is expected to turn painful memories into sweet memories, and vice versa. The project leader of this research, Nobel Prize winner in Physiology or Medicine in 1987, Tonekawa Jin said that this research may provide a basis for psychotherapy, help patients dig out good memories, and eliminate bad emotions. With the development of science and technology, perhaps there will be “Forget Worry Grass” and “Forget Love Water” in the future.
  ”Thunderbolt Five”: fully automatic military robot
  In “Thunderbolt Five” directed by John Bandham in 1986, “Number Five” was originally a military robot with the most sophisticated laser weapons. However, after being struck by lightning, it had a ghostly human consciousness.
  In real life, there are also many real military robots, which are mainly used to find and eliminate bombs and other dangerous tasks, such as the “Dark Soldier” bomb disposal robot developed by the Indian Defense Research and Development Organization (DRDO). The developer said that this robot weighs 380 kg and uses a 6-wheel design. It can use its built-in X-ray to confirm whether a device is an improvised explosive device (IED). If it is, the built-in water spray system of the robot will make it invalid.
  ”Back to the Future 2″: hoverboard
  in Robert Zemeckis directed the 1989 movie “Back to the Future 2”, the protagonist Marty stepping suspension skateboard scene is impressive. At that time, many children saw this scene and wanted to own such a skateboard.
  Fortunately, children today may be able to truly own it. American California architect Greg Henderson has developed a hoverboard called “Hendo”. It has 4 motors that release electromagnetic fields, which can keep it in suspension. Although this skateboard can levitate 2.5 cm, it can only float on a specific metal surface, which is different from the hoverboard in Back to the Future 2. This hoverboard is based on electromagnetic fields, weighs 18 kg, and can last for 7 minutes with a built-in battery.
