Beijing time, September 8, 2013, the International Olympic Committee President José Luis Rodríguez announced in Buenos Aires that the host city of the 32nd Summer Olympic Games in 2020 will be Tokyo, with a period of July 24th to August 9th.
Wei Jizhong, former secretary-general of the Chinese Olympic Committee, said in response: "Two new things appeared at the 1964 Tokyo Olympics: the elevated ring road and the Shinkansen, both of which were pioneered by Tokyo, Japan, at the time in order to host the Olympics, and which had an impact on the world. We can foresee new creations in terms of high technology when Tokyo hosts the Olympics." With the preparations for the 2020 Tokyo Olympics, a number of new products and technologies based on serving overseas tourists, enhancing the experience of athletes and spectators, and advocating environmental protection have emerged one after another in people's eyes. These new products incubated by the Olympics will also be written in the history of science and technology.
Speaker
Panasonic Japan recently launched by the local media as "Japan's secret weapon" of the new product - translation of the megaphone. It looks very similar to the common hand-held megaphone, the role is similar, the special place is that the user speaks Japanese into the speaker, within a few seconds, the speaker can be repeated in English, Korean or Chinese.
This kind of translating megaphone can be used to broadcast to foreign tourists as well as in extreme situations such as disaster relief. Britain's Mirror newspaper commented that Japan hopes to make the 2020 Tokyo Olympics a futuristic Olympics, and by then, there may be a large number of robots involved in the Olympic Games service, and this kind of loudspeaker may make a big difference during the Olympics. 8K TV Programs The Japan Broadcasting Corporation (NHK) began test broadcasting 8K "ultra-high-definition" TV programs on August 1, the first time in the world, and NHK plans to popularize 8K TV programs by 2020, according to a report by the Japan Broadcasting Corporation.
According to a report by the Japanese news agency Jiji Press, 8K programs have a resolution of 7680x4320, which is 16 times higher than that of ordinary high-definition programs, and provide an immersive ultra-high-definition image effect, but 8K TV signals cannot be received by home televisions at the moment. 8K-enabled televisions have been set up at NHK's branches across Japan, and several public **** viewing spots have been set up in Tokyo and Osaka for the public to experience the program. NHK plans to officially start broadcasting 8K TV programs by 2018, and to officially popularize 8K TV programs by the time of the 2020 Tokyo Olympics. Tokyo Olympic Village to focus on hydrogen energy Tokyo City Hall officials said on January 5, 2015, the 2020 Tokyo Olympic Games athletes village will use hydrogen energy as the main source of energy, the end of the Olympic Games, the Olympic Village will be transformed into a clean and non-polluting "hydrogen town". The Olympic Village will be located at Harumi Pier in Tokyo and will host about 17,000 athletes and coaches during the event.
The Tokyo Metropolitan Government intends to build several hydrogen stations and lay pipelines to deliver hydrogen to the Olympic Village's accommodation, dining and sports facilities. The buildings will contain "fuel tanks" in which hydrogen is mixed with oxygen to generate electricity and hot water. Buses transporting athletes will also use hydrogen fuel, which will be loaded at special hydrogen stations. 3D maps Japan hopes to have self-driving cars on the road by the time the 2020 Tokyo Olympics begin. To that end, Japan will begin developing 3D city road maps to aid self-driving cars on the road.
To carry out this project, Mitsubishi Electronics, nine automakers and several map production companies have joined forces to establish the "Dynamic Map Planning" program. In the initial phase of the project, vehicles equipped with special devices will drive on major arteries across the country to collect information and conduct mapping. 3D maps can provide more detailed and accurate road information than GPS navigation, including the status of buildings, road signs, and road grades in the mapped areas. With the help of 3D maps, self-driving cars can react to specific road conditions, such as increasing horsepower on uphill slopes and slowing down in advance of sharp turns, making their driving safer.
According to a report by the Japanese news agency Jiji Press, Hitachi Group conducted a demonstration experiment of the humanoid passenger robot "EMIEW3" on Sept. 2 at Haneda Airport in Japan. This robot has artificial intelligence, but also can use foreign languages to deal with guests. In the experiment, two robots cooperated with each other to navigate a woman playing the role of a foreign tourist.
The Hitachi Group plans to start service in 2018 and put it to use at the 2020 Tokyo Olympics and Paralympics.
The specialty of "EMIEW3" is the cooperative reception of guests at airports or business places by multiple robots. In experiments, staff confirmed that the robot can hear the voices of service recipients in noisy environments such as airports, which are filled with a variety of sounds such as boarding instructions. Hitachi Group Chief Operating Officer (COO) Kan Sato said, "I hope that in 2020, there will be many 'EMIEW3s' 'entertaining' guests."
Cooling roads
Heat is expected to be intense during the 2020 Tokyo Olympics and Paralympics, according to Japanese media reports. Special pavements have been created on some roads in Tokyo to ease the heat.
Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) held a test run on a roughly 250-meter-long section of National Highway 246 in Tokyo's Shibuya Ward. The surface temperature of the road sometimes exceeds 60 degrees in the middle of summer, and to prevent the temperature from rising, the asphalt of the road is mixed with water-retaining materials, and the surface of the road is also coated with infrared-reflecting heat-insulating materials in order to verify the effectiveness of the special road surface. It is reported that the temperature of the road surface with the heat-insulating material is 5 to 6 degrees lower than that of the ordinary road surface.
Former Olympic marathoner Toshihiko Sego and others ran a test run on such roads on the morning of August 31st. After the test run, Segou appealed, "Athletes' lives are in danger when they compete in the summer. I hope that such roads will be used as much as possible so that all participants can run the course." Bio-Jet Fuel The Next Generation Aircraft Fuel Initiative (NGAFI), which includes Japan Airlines, All Nippon Airways, Boeing, and the University of Tokyo, announced in July 2015 a schedule for supplying bio-jet fuel by 2020, when the Tokyo Olympics will be held. By then, biofuels produced from algae and garbage will power airplanes.
The organization will reportedly draw up a detailed plan by the end of March 2017, and in fiscal 2019 it will carry out test runs of the production equipment. Producers of biofuels and the aviation industry will actively work towards this goal.
Shinji Suzuki, a professor at Tohoku University Graduate School, said, "There will be a surge in airplanes flying to Japan in the Tokyo Olympics. It is Japan's duty to provide fuel with lower carbon dioxide emissions." Spectator seating with 360-degree viewing The new National Stadium, the main venue for the 2020 Tokyo Olympics and Paralympics, will introduce cutting-edge technology. This includes equipping each spectator stand with a dedicated monitor, which means it will be possible to watch the games in 360 degrees.
It is reported that seven companies in Japan, respectively, from the promotion of better performance of the players, venue safety, diversity and other five aspects of brainstorming, put forward specific ideas. For example, in the game image to add technical analysis, in addition to the use of the field can also be used in school education; the use of multi-language translation system to provide information; to create a Wi-Fi for 80,000 people to use the network at the same time; in the event of a disaster, it can be used as an evacuation facility, and so on.
