Global meeting through 3D hologram, is it possible now?
When the sun rises and in the morning in earnest, thousands of people begin to flock to subway stations and bus stops. I work through a time period called ‘Rush Hour’ by sitting in an office chair. As we entered the untact era covered by the corona virus, schools were conducting remote classes, and office workers were telecommuting and videoconferences from home. This is virtually unprecedented. During the long time fighting against COVID-19, inevitable technological advances have been made. It was because work had to be done smoothly without any obstacles at home just like working in the office. Through interactive cameras and microphones and networks, we are connecting with others remotely. Isn’t it an era in which global meetings through displays have become possible enough, even for people who are far away abroad?
Occasionally, you will encounter these scenes in movies as well. Eggsy (Taron Agerton) and Kingsman leader Arthur (Michael Caine) are sitting in an empty conference room. Kingsman agents, which were invisible to the naked eye, can be seen at a glance after wearing special glasses. When the meeting is over and they take off their glasses, the appearance of those who disappear as soon as possible can be realized as a 3D hologram. 2015’s work In addition, the Marvel Cinematic Universe is one of the works that dealt with hologram meetings the most. In this case, it is enough to summon Captain Marvel (Brie Larson) beyond the distant universe. It is not only the 3D hologram technology that can communicate without any obstacles, but also the communication infrastructure that far surpasses the 5G network.
Thinking about it Such holograms also appeared frequently in Tony Stark’s studio in Malibu, which appeared in The Movie. Whenever Jarvis, an artificial intelligence assistant, was summoned and looked at complex blueprints or checked maps, everything that appeared in front of him was a real hologram that was almost three-dimensional. A hologram is a ‘image’ that appears three-dimensional even when there is no real thing at all. It is a compound word combining the Greek words ‘Holos’ meaning ‘complete’ and ‘Gramma’ meaning ‘information’. A hologram is a small, flat record made to identify counterfeit items on banknotes or specific cards. The three-dimensional hologram that appears in the movie should be viewed as an ’empty image’ that is only possible in science fiction. In order to realize a hologram that is produced in a movie, it is necessary to be able to handle both the intensity and direction of light even if the same laser beam is emitted. Light emitted into the atmosphere also utilizes the ‘light interference’ effect caused by overlapping two or more rays.
In order to show a realistic hologram as if it appeared in front of me, various infrastructures are needed, from data processing technology to light control technology, communication network, and simulation technology. actually To achieve real-time communication between team members, it requires hologram technology as well as three-dimensional technology called teleportation. Teleportation is said to be ‘teleportation’, but it does not actually exist, so it is only drawn as a ‘image’. so put it together Holoport TechnologyIt is said It is a technology that implements a real-time hologram through a 3D camera. After 3D scanning is preceded, digitally compressed and transmitted over a network. However, everything has to be done in real time, but in some cases it can take several minutes. Taking a recent example, Dr. Josef Schmid, a specialist in NASA, also appeared as a 3D hologram on the International Space Station ISS, which exists outside Earth.
The New York Post saw this and said, ‘It’s like a scene from Star Trek’. You do not need to wear special glasses like Even if it shows a crude appearance without the same sense of reality You don’t even need to wear special glasses. However, with the current communication technology, a communication delay of 20 minutes is inevitable. Nevertheless, what a remarkable development, giving the feeling of being in one space. The mixed reality display mounted on the International Space Station and the Hololens provided by Microsoft are said to be Holoport’s representative technologies. Microsoft also said that it would sign a contract with the US Army and upgrade it as a military HoloLens. Still, he said that the HoloLens headset can be purchased by anyone.
It is difficult to produce a natural result like a scene from a sci-fi movie with existing technology, but you can feel the technology that continues to evolve. As hologram technology evolves further, it is expected that it will be able to be used in various fields, from simple communication to advancement of military strategy, practical non-face-to-face telemedicine, and establishment of cultural contents.
